in the following circumstances:
1, Mary Mulqueen was born on 9 May 1952 and was 57 years of age at the time of her death.
She is survived by her husband John and children Jodi Sissons and Alanagh Mulqueen, with
whom she maintained close and loving relationships.
MEDICAL BACKGROUND
- On 23 June 2008 Mrs Mulqueen attended upon general practitioner Dr Oi Chan presenting
with a history of two days of vomiting following two weeks of nausea, feeling bloated in the
abdomen and experiencing upper abdominal discomfort. Dr Chan ordered multiple tests
including blood tests, a full blood examination, liver function test, C-reactive protein test,
urea and electrolytes test, thyroid function test and carcinoembryonic antigen tests. He also
ordered renal tract and abdominal ultrasounds, and prescribed Nexium 40mg daily for
symptomatic relief of her gastric symptoms.'! Mrs Mulqueen was monitored by Dr Chan and
on 4 July 2008 she reported that she had put on 2kg of weight but was still experiencing
spasmodic vomiting, nausea and lower abdominal pain.” Up until July 2008 Mrs Mulqueen
continued to work at Myer three days a week.’

3, Mrs Mulqueen was diagnosed with chronic gastric duodenal ulcer with scarring and distal gastric outlet obstruction, as a complication of her duodenal ulceration. As these diagnoses were unable to be resolved with conservative treatment, she underwent a distal gastrectomy and vagotomy at Frankston Community Hospital on 20 August 2008.* During the procedure, there were no unexpected findings or problems associated with the surgery reported. There was also no record of vascular injury or abnormal bleeding during surgery. The surgery was performed by A/Prof Colin Russell, with the assistance of surgical registrar Dr Yihua Xie.
A/Prof Russell reported that the postoperative course was complicated. with initial gastric emptying problems, which is not uncommon with the type of surgery performed. Mrs Mulqueen developed lobar pneumonia after surgery and was discharged from hospital on 2
September 2008. At that time she was consuming a normal diet.
- Mrs Mulqueen was reviewed post-operatively on a number of occasions, and was reported to be improving as expected. On 11 and 25 September 2008 she was reviewed as an outpatient by Dr Xie, who stated that on 25 September 2008 Mrs Mulqueen complained of continuing left lower quadrant pain. A/Prof Russell attended, reviewed Mrs Mulqueen and suggested no acute issues arising post-operatively. They arranged for Mrs Mulqueen to be further reviewed in four weeks, and in October 2008 she saw a dietician. In November 2008 Mrs Mulqueen was again seen by Dr Xie and reported diarrhoea and weight loss. Dr Xie’s plan was for monthly medical reviews and ongoing support with the dietician, who reviewed her that day and introduced Codeine and Imodium into her diet. Dr Xie did not see Mrs
Mulqueen after this review.°

On 15 December 2008 Mrs Mulqueen attended upon general practitioner Dr Peter Shea and complained of failure to gain weight and diarrhoea following her surgery on 20 August
-
She was referred to a physician specialising in nutrition, but due to continuing problems was referred to general practitioner Dr Malcolm Scott, who admitted her to The Bays Hospital for total parenteral nutrition (“TPN’), which took place on 30 December

That day she was seen by surgeon Mr Tilan Beneregama, who felt that there was no feasible surgical intervention. Mrs Mulqueen was also scen by gastroenterologist Dr Thuy
Dinh on 2 January 2009, who performed a gastroscopy and colonoscopy, which showed

severe gastroparesis. A gastrografin was performed on 8 January 2009 showing that the contrast flow was slow, consistent with denervation of the stomach, as was to be expected given the nature of surgery performed.’ Three upper GI endoscopies were also performed on 6, 9 and 13 January 2009 to determine whether there was any mechanical obstruction at the anastomosis and to insert a fecding tube into the small bowel. The views of the stomach were severely limited because of residual undigested food. Consequently, the site at the
alien 8 antrectomy was not visualised.
Mrs Mulqueen’s diarrhoea eventually settled and although her weight gain was minimal the TPN was ceased on 16 January 2009, nasojejunal (‘NJ’) feeding was started and she was discharged on 20 January 2009 fully mobile and feeling well, with no diarrhoea and minimal weight gain.” On 3 February 2009 Dr Dinh reported that Mrs Mulqueen had been tolerating the NJ tube feeding very well, was feeling a lot better, had been eating small amounts orally and scemed to be keeping it down quite well. Her cnergy levels had returned and she had been quite active at home and around the gardens. Dr Dinh advised that she continue with
NI tube feeding for the next four weeks and return to see him.'°
On 18 February 2009 and 17 March 2009 HepatoPancreatoBiliary surgeon Mr Peter Evans saw Mrs Mulqueen, On 18 February 2009 she reported that with NJ feeding her weight had stabilised, her general health was improving, she was allowed to have more solid foods over the last two weeks and her diarrhoea had settled so that she was having one or two formed stools per day. Mrs Mulqueen informed Mr Evans that Dr Dinh identified a gastric outlet obstruction that was balloon dilated. Mr Evans reported to Dr Dinh that this information raised the possibility that her gastric symptoms may be ‘more due to persistent outflow obstruction rather than a gastroparesis.’'' Mr Evans was of the view that there may have been.a mechanical obstruction at the site of the gastrojejunostomy. He discussed this with Dr Dinh who stated that he felt there was no mechanical obstruction at the gastrojejunostomy and that the best test was a gastroscopy which he had already performed.
Dr Evans stated that an aberrant reconstruction after the surgery on 20 August 2008 was

definitely a differential diagnosis for her symptoms but that Mrs Mulqueen’s symptoms at her second consultation on 17 March 2009 including her diarrhoea settling, maintaining a stable weight and tolerating a reasonable diet made the diagnosis less likely and far more
likely to be related to gastroparesis.”
In mid-June 2009 Mrs Mulqueen’s liver function tests deteriorated, She was referred to gastroenterologist Dr Michael Merrett for a second opinion and ongoing management. On 22 July 2009 Mrs Mulqueen saw Dr Merrett and complained of being extremely unwell with fatigue, weakness, abdominal bloating and pain. She was also experiencing diarrhoea with 10 stools daily with urgency and had a history of progressive loss of weight. She reported being 50kg prior to her surgery on 20 August 2008 and had dropped to 35kg in the following seven months,!? Dr Merrett performed an upper GI endoscopy on 31 July 2009, which revealed a large amount of food debris within the stomach, despite 24 hour fasting, and a narrow gastroenterostomy with associated firm stomal ulcer occupying half the circumference. Attempts were made to place a percutaneous endoscopic jejunostomy (‘PEJ’) however there was overlying sigmoid colon. Consequently, a percutaneous endoscopic gastrostomy (‘PEG’) was placed adjacent to the gastroenterostomy.!* As Mrs Mulqueen required a prolonged in-patient stay with close supervision of a feeding program, particularly to prevent refeeding syndrome, she was transferred to Jessie McPherson Private
Hospital on 4 August 2009.
Upon admission, Mrs Mulqueen had significant weight loss, protein-calorie malnutrition and profound markers of malabsorption with an Albumin of 12g/L, hypokalemia, hypomagnisemia and low vitamin D. On 5 August 2009 Dr Devonshire underwent a gastroscopy which revealed ‘a good sized gastric remnant with food residue of poor gastric emptying and healthy PEG site’. The gastro-enterostomy bypass in the stomach was ocdematous but not stenotic, although mildly ulcerated. This appeared benign and was nonmalignant on biopsy. The distal small bowel appeared healthy. Enteral nutrition was commenced through the PEG tube to help support Mrs Mulqueen’s nutrition and improve
her clinical state. As she was fed through the PEG there was discharge and irritation at the

tube site for which a CT scan was planned to exclude any other intra-abdominal malignancy
. 15 or obstruction.
By 8 August 2009 Mrs Mulqueen had become quite unwell with profound weakness and was bed bound with crampy pain and a distended abdomen. There were ascites leaking at the PEG site. It was noted her serum Albumin was only 12g/L,'° which can be caused by several different problems, including poor nutrition or inflammation of sepsis.'’ In the early hours of 9 August 2009 Mrs Mulqueen was noted to have systolic blood pressure of 70, sepsis and abdominal pain, and was consequently transferred to the Intensive Care Unit.
Her condition deteriorated rapidly and Dr Devonshire assessed her as being critically unwell with the possibility of progressive malignancy, intestinal failure and severe malnutrition. A CT scan of her abdomen suggested the possibility of free gas and bowel leak. Mrs Mulqueen was assessed by the surgical team, including Mr Graham Starkey. On review she had a distended tense abdomen and was acidotic, anuric and requiring noradrenaline to maintain her blood pressure. The surgical team discussed Mrs Mulqueen’s critical condition
with her family and procecded with laparotomy.”
At laparotomy Mr Statkey found ischaemic’? bowel from proximal jejunum to rectum, a previous distal gastrectomy, a distended gastric remnant anastomosed to distal ileum with the ileal limb anti-peristaltic, and ileo-ileostomy with only a short segment of bowel between the stomach and caecum and the remaining small bowel bypassed. Mr Starkey noted in his hospital progress notes that the reconstruction seemed to have been incorrectly performed.”° He spent some time in theatre examining the anatomy duc to its unusual nature, including unscrubbing midway through the procedure to speak with a senior colleague, Mr Stephen Blamey, due to the significance of what he had found and arranging for photos to be taken. He determined that there was no chance of survival. Mrs Mulqueen’s abdomen was closed, she was returncd to ICU for palliation and passed away at 2.45pm _ that

Due to his findings Mr Starkey referred this matter to the Coroners Court of Victoria”!
POST-MORTEM EXAMINATION
A post-mortem examination and report was conducted by Dr Michael Burke, Senior Forensic Pathologist at the Victorian Institute of Forensic Medicine. Dr Burke reported that at post-mortem examination the bowel did not have as florid an appearance as suggested by the medical records, however there certainly was microscopic evidence of ischaemic change within the submucosa and muscle coat of the bowel. There was no evidence of frank gangrene or peritonitis. He further reported that the surgical anastomoses appeared intact but that the issue of ‘anti-peristaltic’ position of ileo-gastric anastomosis was beyond his field of
expertise.
Dr Burke determined that the cause of death is 1(a) small bowel ischaemia; and (2) distal
gastrectomy.
PURPOSE OF THE CORONIAL INVESTIGATION
1S.
The primary purpose of the coronial investigation of a reportable death” is to ascertain, if possible, the identity of the deceascd person, the cause of death (interpreted as the medical cause of death) and the circumstances in which the death occurred.” An investigation is conducted pursuant to the Coroners Act 2008 (Vic) and the outcome of this part of my
investigation is included in this finding.
Coroners are also empowered to report to the Attorney-General on a death they have investigated; the power to comment on any matter connected with the death, including matters relating to public health and safety or the administration of justice; and the power to make recommendations to any Minister, public statutory or entity on any matter connected.
with the death, including recommendations relating to public health and safety or the
administration of justice.” This is referred to as the ‘prevention role’ of the coroner.
4 Thid 110.
22 Section 4 of the Coroners Act 2008 (Vic) requires certain deaths to be reported to the coroner for investigation. Apart from a jurisdictional nexus with the State of Victoria, the definition of a reportable death includes all deaths that appear ‘to have been unexpected, unnatural or violent or to have resulted, directly or indirectly, from accident or injury. Mrs Mulqueen’s death falls within this definition.

THE EVIDENCE
2l.
This finding is based on all the investigation material comprising the coronial brief of evidence, all material obtained after the provision of the brief, the statements and evidence of those witnesses who appeared at the inquest and any documents tendered through them,
other documents tendered through counsel, as well as written submissions made by counsel.
The following witnesses gave evidence at the inquest:
e = Dr Thuy Dinh
. Mr Graham Starkey
e Dr Michael Burke
e Dr Matthew Andrews
e A/Prof Ronnie Ptasznik
e A/Prof Wendy Brown
e A/Prof Colin Russell
L also received written submissions from Mr James Fitzpatrick of counsel for the Mulqueen
family and Mr Ben Ihle of counsel for A/Prof Russell.
At the commencement of the inquest, it was evident that most of the facts about Mrs Mulqueen’s death are known including her identity, the medical cause of her death and aspects of the circumstances, including the place and time of her death. The primary focus of the inquest into Mrs Mulqueen’s death related to circumstances surrounding her death; in particular, whether an inadvertently aberrant surgical reconstruction was performed by A/Prof Colin Russell and/or his assistant, surgical registrar Dr Yihua Xie, during the course of the distal gastrectomy and vagotomy procedures undertaken at Frankston Community Hospital on 20 August 2008. I note that Mr Xie was not an interested party to these
proceedings and that the Court has accepted his statement as untested.
It is important that I make clear that it is not part of a coroners role to lay or apportion blame. As Calloway JA espoused in Keown v Kahn (1999) VR 69: Tn determining whether an act or omission is a cause or merely one of the background circumstances, that is to say a non-causal condition, it will sometimes be necessary to consider
whether the act departed from a norm or standard or the omission was a breach of a recognised
duty, but that is the only sense in which para. (e) mandates an inquiry into culpability. Adopting
8 of 50
22,
the principal recommendation of the Norris Report, Parliament expressly prohibited any statement that a person is or may be guilty of an offence. The reasons for that prohibition apply, with even greater force, to a finding of moral responsibility or some other form of blame: the proceeding is inquisitorial.?* Callaway JA observed that it is the coroners role to seek to establish the facts, set them out and for others, if they wish, to draw legal conclusions. The amendment to Coroners Act 1985 (Vic) repeals the requirement to make a finding as to persons/other entities who “contributed” to the death, due to the connotation that had attached to that concept; a connotation of fault, blame or culpability. T have assiduously sought to follow His Honour’s
direction.
The Briginshaw’’ standard of proof is applicable to findings of fact in this Court. As Dixon J
espoused:
The seriousness of an allegation made, the inherent unlikelihood of an occurrence of a given description, or the gravity of the consequences flowing from a particular finding are considerations which must affect the answer to the question whether the issue has been proved to the reasonable satisfaction of the tribunal. In such matters ‘reasonable satisfaction’ should not be produced by inexact proof, indefinite
testimony ot indirect inferences.”
Evidence at Inquest
24,
At inquest gastroenterologist Dr Dinh gave evidence that when he performed the three endoscopies in January 2009 he was aware that a distal gastrectomy had been performed previously, but did not know the reconstructive configuration of the small bowel, nor would he be able to determine the configuration via endoscopy.” He’ stated that his primary purpose was to look for a gastric outlet obstruction into the small intestine, but that it was difficult to visualise clearly due to the large amount of undigested food remaining in the stomach, Dr Dinh stated that the food remains may have been due to an obstruction or due to
denervation of the stomach muscles as a result of the vagotomy performed on Mrs

Mulgueen.” Dr Dinh stated that on 3 March 2009 he removed the nasojejunal tube because Mrs Mulqueen was gaining weight, was able to eat normally and was quite happy to have the tube removed.! She was not using it at the time, was eating and tolerating her diet, her energy levels had returned and she had been quite active at home and around the gardens, indicating that while she was receiving nutrition via a nasojejunal tube as at 3 February 2009
it is likely that her bowel was uptaking nutrients.”
During cross-examination by Mr Fitzpatrick, Dr Dinh stated that while performing the endoscopy the small bowel was not completely blocked, because he was able to enter into it? He further stated that, assuming Mr Starkey’s diagram of what he saw during the laparotomy performed on 9 August 2009 is correct,** such a structure, with a length of 20cm into the anastomosis, is in his view too short to see the major clinical improvement from the time the nasojejunal tube was inserted to two months later when Mrs Mulqueen saw him, because if it was that short the contents of the feeding fluid would not be absorbed a lot, or
at all.>°
He agreed that if what Mr Starkey found is correct that it would be an unusual occurrence and that it would be fair to say that he would have been surprised that Mrs Mulqueen would have done as well as she did. Dr Dinh stated that he had not come across many cases of this type of surgery at the time that he saw her in 2009 and that he would not have ever seen a patient that he could be confident had what Mr Starkey described. He stated that there is a critical length in which a patient would need lifelong nutrition from other forms rather than orally, but that it depended on many factors and varied from person to person,® but that the critical length for absorption is ‘usually about 60-to about 80cm or so’,” and that patients who have a length of small bowel less than 60 to 80cm run into major issues with malabsorption and requiring intravenous nutritional supplements. In normal
circumstances, with those patients he would not expect to see the improvements he saw in

Mrs Mulqucen, by way of nasojejunal tube insertion or something similar. 38 He stated that if it was the ileum used for the gastro anastomosis, given the length described it is highly likely there would be consequences for Mrs Mulqueen, such as malnutrition and poor
absorption.””
During cross-examination by Mr thle, Mr Dinh stated that Mrs Mulqueen responded quite well to nutrition by the nasojejunal tube and the fact that she received intravenous nutrition while she was in hospital. He explained that gastroparcsis is certainly very frequent in people who have undergone a vagotomy, and that in the period between 3 February 2009 and 3 March 2009 Mrs Mulqueen was on upwards trajectory; she was eating and feeling better and her bowel movements were starting to look more consistent with someone receiving nutrients. He stated that in mid-February 2009 the issue was working out whether there was a mechanical obstruction or gastroparesis, and that he thought it was more likely to be gastroparesis than a mechanical obstruction, as by that stage he had performed three endoscopies and saw no mechanical obstruction.”” He conceded that gastroparesis is not necessarily a static condition and that the natural course of gastroparesis is often periods of problems and wellbeing in between. Dr Dinh stated that he still sees the fundamental problem as gastroparesis that may fluctuate, which is something he would expect to see in
patient after they had received a vagotomy. *!
Mr Starkey gave evidence at the inquest. He stated that at the time he performed the laparotomy on Mrs Mulqueen he had been a Hepato-Biliary & General Surgeon for 3 years and had performed laparotomies fairly frequently. He stated that at the time he would not have seen a huge number of distal gastrectomies but had used the Roux-en-Y procedure a lot, as its configuration is quite common in transplantation and liver surgery, and that there is only one standard way to do it. Prior to performing the laparotomy on Mrs Mulqueen he was aware of what the configuration should be like anatomically with the gastrectomy. He was also aware that Mrs Mulqueen’s pre-laparotomy weight was approximately 34
kilograms.**

Mr Starkey said the purpose of performing a roux-en-Y procedure was to create a distance between the stomach and where the bile is coming down, so that the bile doesn’t go up into the stomach and cause bile reflux.“ In Court, he drew a diagram of a standard Roux-en-Y procedure.” He explained that the antrum is effectively removed after the resection of the stomach and that the first part of the duodenum, just past the pyloris, is the other part of the resected specimen. The jejunum is divided a short distance from the DJ flexure, the distal part of the bowel is joined to the stomach and the proximal jejunum is attached to the side of the duodenum.** Mr Starkey stated that the length from the gastroenterostomy”” to the enteroenterostomy“*® vaties between surgeons from 20 to 50 centimetres, but that 30 to 40 centimetres would be typical, and that the length of the duodenum which had a blind end typically has 30 centimetres of duodenum and 20 centimetres of proximal jejunum.” He stated that a typical adult female would have ‘something like three and a half metres’ of small intestine and that the remaining length from the enteroenterostomy until the ileocecal junction is approximately 2.1 metres, but that the length of the small bowel is quite
variable.*°
Mr Starkey gave evidence that the configuration of the small bowel was unusual, and that a portion of the limb of the small intestine was antiperistaltic,®' The first thing that struck him was the short distance between the gastroenterostomy, enteroenterostomy and ileocecal junction. The second was that the distal ileum was connected to the side of the ileum so that the bowel was joined on the side and you could see it coming into the side, creating a pronounced intersection, whereas he described that usually in a normal situation the part of
the bowel going up to the stomach is in continuity with the ileocecal junction.”
He conceded that he did not use a tape measure and that his measurements were rough, but
that the distance between the entcroentcrostomy and ileocecal junction was approximately

20 centimetres® and that the distance between the gastroenterostomy and enteroenterostomy also measured approximately 20 ccntimctres. When asked if the length between the gastroenterostomy and enterocntcrostomy presented as an issue for him, he replied ‘I don’t think that was a big issue. But it’s the direction, it’s not the length’.“’ Mr Starkey conceded that he did not measure the length of the duodenum which had a blind end, but believed that this was the great majority of the small bowel, ‘probably two or three metres in length,’ and comprised of the duodenum, jejunum and a large part of the ileum,° with exception to approximately 20 centimetres of ileum. He stated that it was working in a direction so that bile and pancreatic juices were coming down the long lip of bowel, but not coming into contact with food and that it is only at the point where food can manage to make its way down the antiperistaltic limb that it can mix with the bile and pancreatic juice. He said that the bulk of the small intestine is antiperistaltic but that from the enteroentcrostomy it is peristaltic, including the colon.” If it is accepted that Mr Starkey’s configuration is correct, he would expect three things. First, he would cxpect it to cause malabsorption; an inability to absorb sufficient nutricnts, because of the short length of peristaltic bowel. Second, if undigested food enters the cecum and colon it tends to cause diarrhoea, therefore he would expect that if there was not a long piece of small bowcl the paticnt would get bad diarrhoea that would be difficult to control. Third, the stomach was “effectively working against a loop of bowel in terms of emptying”. Consequently, he expected that would make it difficult for the stomach to empty and may enlarge the stomach, however he commented that this can be a problem regardless after a distal gastrectomy.”® He said that Mrs Mulqueen already had these symptoms prior to the distal gastrectomy and vagotomy on 20 August 2008, but said the reconstruction may have exacerbated those problems. He stated that it was important to note that nobody has really seen cases like this and consequently it is hard for him to give
any experience of that.*°

In relation to what portions of the small intestine would have been able to properly absorb nutrients, Mr Starkey stated that the 20 centimetres of ileum would be acting normally but that it depends to what degree food would reflux up the limb and mix with bile and pancreatic juices, which he could not determine. The food certainly would not have gone all the way to the blind end/stump, but that peristalsis is not a complete 100% phenomenon, so food could have gone a little way up there. If Mrs Mulqueen had ‘just 20 centimetres of gut, full stop’ he would find it very surprising that she was able to sustain herself, but he ~ does not think anyone has the experience regarding to what degree the other bowel might have been contributing to some absorption, even though it was ‘sort of out of circuit’, and she was receiving at least two months of parenteral nutrition, or nutrition into her veins, which was not dependent on the bowel.®! He agreed that if Dr Dinh’s evidence was correct that the food was released, via a nasojejunal tube 5 centimetres beyond the anastomosis, that
it would have been placing food in the antiperistaltic portion of the intestine.
Mr Starkey conceded that prior to Mrs Mulqueen’s case he had never come across an antiperistaltic Roux-en-Y configuration, that he did not think it would be on any doctor’s radar post this type of surgery and that it would be fair to say that other explanations are often sought in terms of explaining poor stomach emptying and poor absorption. He explained that a lot of questions were about gastroparesis and a stricture as well as thinking about other diseases, like cocliac disease, and that tests had becn done that cast a wide net,
because nobody was sure.
During the procedure, Mr Starkey recalled spending approximately 20 to 25 minutes looking at the configuration, following the bowel along™ and dissecting out the adhesions to make sure that he appreciated the anatomy correctly. He was trying to exclude ischaemic bowel and stated that he ‘certainly never imagined finding something like this’. Approximately 20 minutes into the operation he initially noticed the gut had ischaemic changes.
Consequently he made sure that he very carefully examined the whole gut from the DJ

flexure down to the terminal ileum and ileocecal function to make sure there wasn’t a significant part of it that was still viable. When doing so he noticed the close proximity of the joins from the previous surgery, which ‘rang alarm bells because that was clearly not normal’. He noted that a proximal part of the small intestine had been joined wp to the stomach and the distal end became the enteroenteric anastomosis, which meant that the pathway of anything lcaving the stomach through the gastric anastomosis will travel a reasonably short distance due to the short length of bowel.®” This reconstruction would see the stomach drain directly into part of the ileum, then through another anastomosis into another part of the ileum. Mr Starkey informed the court that he was very confident of
what he saw.
Mr Starkey then traced the bowel up and down a couple of times with the theatre camera. He unscrubbed and spoke to the head of the unit on the telephone, to get a second opinion about his observations regarding Mrs Mulqueen’s bowel configuration and clinical situation. He stated that the second opinion was not a question of second-guessing himself and that the potential gravity of the situation for another surgeon was not at all lost on him at any stage,” He then rescrubbed, took some photos and closed the abdomen. He estimates that this whole process took approximately one hour.”! He stated that from a clinical point of view, which was critical, he looked for if there was a segment of bowel that was abnormal and the rest okay, in which case he would have resected that part. However, the changes were global, in that there was no real difference between all of the bowel; it was all ischemic other than a very small part near the DJ flexure. Consequently, no operation he could sensibly do would potentially help Mrs Mulqueen.” Prior to the operation, he felt the chances of survival were low and that the operation would probably not change the outcome, but he wanted to demonstrate to the family that they were doing everything they could.” Mr Starkey gave
evidence that ischaemic gut causes are multifactorial and that he does not know what the

final cause for her ischaemic gut was,” and confirmed that whatever factors caused Mrs Mulqueen’s dramatic demise occurred over the last couple of days, rather than weeks or
months.”
Mr Starkey gave evidence about Mrs Mulqueen’s condition on the morning of 9 August
2009, based on Jessie McPherson Private Hospital medical notes.”° He explained that Mrs
Mulqueen had quite low systolic blood pressure of 70, decreased albumin, which could be caused by a range of factors including poor nutrition or inflammation of sepsis, raised C reactor for protein (CRP) of 250, a blood marker showing that there is some degree of inflammation, increased heart rate of 125, which is one of the body’s responses to severe inflammation, and drowsiness.” He stated that now knowing his findings on the laparotomy, and reflecting back on these symptoms, certainly having ischaemic bowel causes a lot of inflammation and sepsis and a high heart rate, although he commented that it would be unusual to have acute inflammation from ischaemic bowel to cause a CRP to be that high as early as that.”’ The medical notes recorded that Mrs Mulqueen was scverely malnourished.
and Mr Starkey gave evidence that this would cause a degree of immuno-compromise which makes it harder for the body to fight infection. He could not say why or what made Mrs Mulqueen so unwell on that night, or why her blood pressure was so low.” He did not know what event made her gut ischaemic,” and agreed that the autopsy photographs did not show frank necrosis of the bowel, and that the bowel did not have as florid an appearance as suggested by the medical records.*' He further stated that he is not suggesting that Mrs Mulqueen’s death was caused by an aberrant procedure performed a year or so earlier, but rather that she developed ischaemia, or profound sepsis and abdominal pain, which caused him to perform the operation whereby he found the evidence of the previous surgery, but
that the cause of her death was, he believes, a gut ischaemia.”

Dr Michael Burke, Senior Forensic Pathologist at the Victorian Institute of Forensic Medicine, gave evidence that he performed an autopsy on the body of Mrs Mulqueen on 14 August 2009. He acknowledged that in his 18 years as a pathologist he does not believe he has seen an improperly performed Roux-en-Y reconstruction at autopsy, but that it is not uncommon for him to see Roux-en-Y reconstructions at autopsy. During the autopsy on the body of Mrs Mulqueen, Mr Burke measured that the length from the gastro-intestinal junction down to an anastomosis was 29 centimetres. He did not measure the length from
the blind end to the end of the small intestine.™
Dr Burke noted that some parts of Mrs Mulqueen’s bowel showed changes of ischaemia under the microscope but that, to his eye, it wasn’t global ischaemia of the small bowel.
The details that informed his view that there was ischaemia to the bowel were really upon histological examination rather than macroscopic; he took a numbers of sections. He stated that the bowel, as he observed it, would be the same or worse than on the day it was operated on by Mr Starkey.®* He conceded that in his autopsy report he referred to a gastroileal anastomosis,” but that ‘from the strict anatomy it may well be jejunal”®’ and he
would now say ‘ gastroenteric’.**
When revicwing photograph one taken by Mr Starkey in surgery” Dr Burke stated that he would absolutely take Mr Starkey’s word that there is nothing on the fact of that which does not look right; that it looks to be the correct anatomy.” He gave evidence that Mrs Mulqueen also had chronic ischacmia changes, and that it is hard to understand regarding someone who had normal blood vessels. He said that it is certainly unusual why Mrs Mulqueen suddenly became acutely unwell atid dropped her blood pressure,” and agreed that it did not help that she lost a lot of weight, from 50 kilograms to approximately 34
kilograms in 12 months, and was in quite a malnourished state, but does not know whether

that necessarily caused her to drop her blood pressure.” ? He agreed that her malnourishment, weighing 34 kilograms, meant that she would not tolerate surgery as well as if she was fit
and well.”?
During cross-examination, Dr Burke commented, when looking at photograph one taken by Mr Starkey in surgery, that ‘the bowel looks sick, it looks dilated. It’s not frankly gangrenous but it looks unwell’.* He could observe three defined anatomical points which he said were unmistakable: the gastro anastomosis, enteroenteric anastomosis and the terminal ileum.” He stated that generally, with respect to mapping the DJ flexure it is pretty obvious in routine practice of someone who has died of a heart attack. He agreed. that in his autopsy report he noted that something that he originally considered was an anastomosis was actually an adhesion upon dissection, and that this is a complicating factor because adhesions make mapping the small bowel that much more difficult,” but gave evidence that
the autopsy photographs show that there are not a lot of adhesions.”
Dr Burke conceded that his gastroesophageal junction measurement in his autopsy report is not of great relevance or assistance, and that he did not measure the area of the bowel as Mr
Starkey had done:
Rather than - if I had have measured, rather, from the oesophagus to the gastroenteric anastomosis — which is a pretty silly thing to do in retrospect — If T had it the other way around this would be resolved very quickly. Unfortunately, I’ve gone straight to there and I haven’t done as Dr Starkey has done. And I’ve looked at the bowel and I
don’t think I’ve appreciated the enteric anastomosis, which | apologise for.
Dr Burke gave evidence that as an experienced pathologist, he would have thought it highly
unusual for a qualified surgeon such as Mr Starkey, specialising in surgery of that nature, to

that you take photographs is an important thing’.”
He said that it is uncommon for pathologists to see surgery notes with comments like that

There was nothing in the autopsy examination, or in the documents by reason of Mr Starkey or his own. photographs, which says that the anatomical configuration was the same as that shown in diagram ‘B’, not diagram «A? 102
Dr Burke stated that 40 centimetres of bowel that would be in circuit is not necessarily something he would note, unless he was specifically looking for it, and that when looking from a point of juncture at the bowel to another fixed point, he was certainly aware of the anastomosis at the exit point to the stomach, but was not aware of the anastomosis distal to
that and believes that he missed it,!°
He conceded that he may well have accepted Mr Starkey’s view of what the internal anatomy was, and inter-relayed that into what he was trying to convey, but that based on the photos and on his own independent examination, he cannot say that that is in fact the case, and cannot say whether it is the configuration as
depicted by diagram ‘A’ or diagram «pr 04
Concurrent evidence was given by radiologists A/Prof Ronnie Ptasznik and Dr Matthew Andrews. Both radiologists gave evidence that they have interpreted a large number of gastrografin flowcharts/studies throughout their careers and would have been doing
approximately 10 to 15 a day when they were first cutting their teeth in radiology. 105
In relation to the gastrografin flowcharts/studies tendered as evidence,'® both radiologists
agreed on seven points:

a) The technique is sub-optimal, especially given the clinical indication of malabsorption.
They would have done far more images between 90 minutes and 4 hours to assess the
state of the mucosal lining. Compression/distension views were not available; b) They are somewhat critical of the choice of gastrografin rather than barium;
c) The stomach is distended, the gastrocntcral anastomosis and jejunal loops fill carly?” in the examination and there is a lack of small bowel gas in the right upper quadrant of the
abdomen;
d) There is delayed gastric emptying with food and debris present. There is contrast still present in the stomach at four hours which means that the contents of the stomach had
difficulty in emptying; e) The large bowel is opacified at 90 minutes; f) At the time the large bowel is opacified large amounts of small bowel are not opacified;
g) The four hour film shows large and small bowel but differentiation between what is small and large bowel in the pelvis is impossible, because they are superimposed one upon the other, and there is still residual contrast within the stomach. No small bowel
was seen in the upper abdomen.’
A/Prof Ptasznik and Dr Andrews held differing views on a number of points, including determining the length of small bowel. Dr Andrews, who said that Mrs Mulgqueen should have approximately six to seven metres, or approximately 25 feet of small intestine,’ gave evidence that interpretation of length of small bowel is difficult, particularly when loops are superimposed and that his degree of confidence of the length of small bowel is difficult to

Mulqueen’s images are not of a normal patient due to her past medical history and

procedures, '” and distended stomach.'"* In relation to an explanation for the early filling of the colon, Mr Andrews said that a fistula is one possibility and the other is that there is not much small bowel-due to it being either bypassed or removed,'’ and that it has gone
through to the colon very quickly.” He thought it to be very, very unlikely for a surgeon
performing the procedure performed by Mr Starkey to miss six or seven metres of small
bowel if he was specifically looking for it.''%
A/Prof Ptasznik did not think that six or seven metres of small bowel opacified in Mrs Mulqueen’s study; he believed it was less than half.''’ He agreed that the study is suboptimal, but ‘made allowances for this in his brain’ and said that there is far less small bowel opacified than he would expect. He could not say whether it is absent or just non-opacitied,

proximal small bowel, gas or mass effect in the upper abdomen and he did not think the stomach was distended enough to displace all of it in the pelvis. He did not think the matted loops of small bowel would obscure seven metres. Due to these factors, he thought the most likely explanation is that the small bowel in question is not there, rather than there being a fistula.'!° He thought it unlikely there was a fistula, but could not exclude it completely. The lack of small bowel gas in the studies and total absence of jejunum opacified at four hours,
and in the upper abdomen at all stages of the study, might be because the stomach was so
distended that it pushed all the bowel down. 120
A/Prof Ptasznik believed the most likely explanation for the findings is that a large amount of small bowel, which he said could be four to five metres, is absent/not visualised, and that the study demonstrates a loop of jejunum blind ending and probably represents the afferent loop of the Roux-en-Y.’”’ The 10,19 film shows ‘pretty much all the small bowel that was
opacified’ and no large bowel, and the 10.28 film has ‘unquestionably large bowel present’

on the film, meaning the transit from small to large bowel took place in that nine minutes.
He stated that if that is all the small bowel then that is a substantial difference from the volume of small bowel he would expect to be present in a normal study film.’ Even allowing for clumping and displacement following surgery, the amount of small bowel loops, approximately 2 metres, opacified at the beginning of the nine minutes is not seven metres and he did not think there was enough time for the contrast to have passed through
the remaining five metres.'°
Looking at films 9:52 and 10:19,'”* he was confident the featureless toothpaste tyre loops is almost certainly ileum, based on the fact that very soon after the large bowel is seen the ileum anastomosis joins with large bowel. Dr Andrews did not have the same degree of confidence on the bases that the images are not as optimal as he would have liked and
because he does not believe the loops are as fully opacified as he would like.'*
Dr Andrews was not prepared to say that there is the presence of a blind loop on the images, due to the limited visualisation the images being two dimensional/one projection’** and the position of the ‘blind loop’ at the 9:52 and 10:19 images which shows the ‘blind loop’ to be too far down into the pelvis from where it would be in a normal patient who underwent a Roux-en-Y procedure,!?” because the blind loop is a fixed object that he had never heard of
being moved surgically or by pressure from other organs or masses within the abdomen. 28
Upper Gastrointestinal and General Surgeon, A/Prof Wendy Brown, gave evidence at the inquest. She performs Roux-en-Y reconstructions on many occasions and her sub-specialty
and post fellowship training was on surgeries involving the stomach and oesophagus.
When looking at the photographs tendered as exhibit 5, A/Prof Brown stated that there are
limitations in making asscssments of the bowel with photographs, and that the colour and
' sheen are difficult to assess. She gave evidence that for persons in the same position as Mr
Starkey it can be difficult to identify the condition of the bowel, particularly if the patient is
on inotropes to support their blood pressure, becausc the drugs can constrict the blood

supply which can compromise the blood flow to the bowel. Consequently, distinguishing the difference between bowel that is not getting enough blood because of drugs administered and bowel that is dying or compromised can be very difficult." After reviewing Mr Starkey’s photos she believed there was global compromise to the bowel and probably patchy areas of ischaemia, but did not think the bowel was universally ischaemic. Albeit with limitations around sheen and contracting of the bowel as viable, she gave evidence that a lot of the bowel looked to be viable in the photographs, and that there was no evidence of gangrenous necrotic bowel in the photographs that she had seen, but that the bowel looked ‘unhappy’ and ‘sick’,
Gl within Mr
A/Prof Brown stated that if the visual landmarks in the labelled photographs Starkey’s statement are as he suggests, there is only approximately 20 centimetres to the enteroenterostomy and approximately 20 to 30 centimetres of bowel where the ileum joins the cecum.’** If she accepted that the evidence of Mr Starkey is accurately described, she said there is a very distended stomach remnant and an aberrant reconstruction where the bowel is. There is ileum going into the stomach and there has been an antiperistaltic limb.
The bowel has been divided too low and they have brought the proximal end of bowel up to the stomach and the distal end down to anastomose as an enteroenterostomy.'* She conceded that there is a problem relying on photographs because she has to rely on Mr Starkey’s description as being correct to arrive at a conclusion that his description is coirect.'°* She could not determine whether the bowel in photograph 1 was ileum or jejunum and stated that in surgery she typically identifies parts of the bowel relative to landmarks. She thought she could be confident that what is in the person’s left hand in photograph | is ileum heading down towards the ileocecal valve because she could see the cecum and teniae coli, but otherwise could only say there was an enteroenterostomy and
could not confidently say whether it was ileum or jejunum."

A/Prof Brown said that during surgery there is potential for confusion as to what is ileum and jejunum when attempting to make a transverse cut. The primary landmark is the duodenal flexure and there is a ligament of Treitz which is also an important landmark.
Upon locating these landmarks, she typically runs the jejunum up between 10 and 30 centimetres until she finds a part where she can comfortably divide the bowel, but stated that if people have scar tissue, previous surgery or previous trauma in the abdomen, the bowel can be a bit stuck which can cause confusion. Something that a surgeon thinks could be the ligament of Treitz could be incorrect and they could confuse scar tissue for that. She stated that that wouldn’t be difficult to have happened and that in surgery there are metres of bowel, your hands can slip and you think you are at a certain point but somehow have found
yourself along the bowel a little further than you thought. 136
When making a transverse cut, she measures out the amount she wants to do and brings that loop up to the part of the stomach where she wants to fashion the join between the jejunum and anastomosis. She checks the blood supply and at all times, keeps it in her hands. She then divides it and puts a marking suture on the proximal end, drops that end, over-sews and fashions the anastomosis. The proximal end is then attached to the enteroenterostomy, which should be 40 to 50 centimetres away from the anastomosis between the stomach and distal end of the bowel. She usually double checks for the ligament of Treitz before dividing, because it is a critical landmark and wants to be 100% sure that she hasn’t become distracted, dropped bowel or that her assistant has not inadvertently picked up another bit of bowel. At the conclusion of the procedure she double checks the lengths, the DJ flexure to make sure she hasn’t reversed it, and that the anastomosis is water tight.’°’ She puts a marking suture on the proximal end because it can be easy to get it around the wrong way,
as both ends look the same, but knows of many surgeons that do not have that practice. 138
If the transverse cut was made lower, much closer towards the ileocecal valve on the ileum, A/Prof Brown believed the surgeon would be aware of a bulk of bowel on both sides of the field and would be more aware of the cecum, which is normally well out of field, but may be
pulled into play a little more if the transverse cut was much lower.

She said three to three and a half metres was the typical length of small intestine in a female 155 centimetres tall and that six to seven metres seems excessive, that she has never seen anyone with seven metres of small bowel, that she measures small bowel quite regularly and.
that the longest small bowel she has measured was approximately five metres,°?
A/Prof Brown stated the reconstruction as described by Mr Starkey would be more rapidly incompatible with life. The classic teaching is that you need at least a metre of gut to live and that patients with only 20 centimetres of functional gut don’t leave hospital and never have periods of time where they are able to be nourished enterally, using either food by mouth or a tube into the bowel.'*° If the reconstruction is as Mr Starkey described there are still metres of viable bowel and there could be some food reflux back in to that bowel that would allow for some absorption of nutrients, because if the food was coming from the stomach and the bowel was antiperistaltic it is hard for the stomach to empty due to the bowel pushing the wrong way. If food did get in presumably there would be some absorption in the bowel that was out of circuit, which differentiates Mrs Mulqueen from
short gut patients. '*!
The reason she questioned the reconstruction described by Mr Starkey was because someone who had that construction would be dependent on TPN and wouldn’t be able to feed themselves enterally. She formed the opinion that there was an aberrant reconstruction and did not think it was a correctly constructed roux limb, but questioned if, in the alternative, the error was just too short a common channel from the enteroenterostomy to the ileocecal valve, where the surgeon inadvertently reconnected the enterocntcrostomy too far down stream, which was why Mrs Mulqueen was able to have periods of feeding herself enterally.
She accepted that if the construction was as Mr Starkey described that some retrograde flow to the excluded piece of bowel may allow for absorption, which may be why Mts Mulqueen was not completely dependent on TPN, but found it hard to understand how one could sustain life on essentially 20 centimetres of bowel without constant TPN. She was very confident that at laparotomy she would be able to determine whether it was an aberrant
reconstruction or shortened common channel. When asked why, A/Prof Brown stated:
'3° Tnquest transcript 376-8.

‘41 Inquest transcript 385.

61,
Because I think if you’re actually at the operation you can very confidently say what’s a gastrojejunal or ileal anastomosis. You can see the anastomosis at the stomach very easily; you can confirm it’s the stomach because there’s usually a tube going from the nose down in to the stomach so you can feel that, also the stomach remnant is where its supposed to be. So you can see an anastomosis, then you can follow that bowel and you can find the next join
and then you can follow the bowel in both directions.”
On this basis, A/Prof Brown accepted that Mr Starkey is ‘probably correct’ as he was there, took photographs and assessed it,’ however she gave a caveat that this occurred during an emergency operation with a very unwell patient and that sometimes in a hurry ones measurements may not be as accurate, and that a shortened common channel would be very
easy to mistake at laparotomy in an emergency situation. Ms
With the benefit of knowing and seeing that he had taken photographs and that he had been able to document as carefully as he has, information which she was not provided in her first report, that tended to suggest to her that he had taken the time to undertake those activities
1.9 She said it does not matter exactly how
and the assessment of the bowel was very carefu the bowel was reconfigured; the net result was that it led to Mrs Mulqueen becoming very malnourished which she believed ultimately contributed to her demise. There was something wrong that nobody was able to pick up over a year prior to Mrs Mulqueen’s demise and that by the time Mr Starkey was operating there was very little he could do to reverse the situation.’ She did not think that Mrs Mulqueen’s weight is a good measure of how well she was nourished over the year, and that it was a poor measure of nutrition.'"’ She said that
a fistula was unlikely.’
A/Prof Brown said that she would expect a surgeon such as herself or Mr Starkey to have very little difficulty locating the gastric anastomosis and that it is quite possible that if Mrs Mulqueen had a distended stomach that photograph one depicts a gastric anastomosis, and
that it is not in the wrong place. She said that Mr Starkey’s evidence of following or

‘walling’ the small bowel until he finds the next anastomosis are fundamentally basic skills for a surgeon of some experience.'” The enteroenterostomy can be more difficult to identify, but from the pictures Mr Starkey provided it is clear that he did identify the enteroenterostomy and ilcocecal valve, and on that basis she accepts there is an aberrant reconstruction.'°° Although she could not see the gastroenterostomy in the photographs, as it is the anastomosis ‘that Mr Starkey would have been readily able to identify at the time of surgery, she said that she has to trust that his labelling is correct.!*! In relation to Mr Starkey’s decision to close the abdomen and send Mrs Mulqueen to ICU for palliation,
A/Prof Brown said that she was of the view that Mr Starkey’s decision was appropriate,’*
A/Prof Brown could see metres of small bowel in the 1:04 gastrografin film and stated that a healthy Mrs Mulqueen would have three to three and a half metres of small bowel and that allowing for parts of the bowel being out of circuit due to the construction of a blind limb on an appropriate roux, the metres of small bowel that she observed on the film is not inconsistent with that," She would expect there to be some peristalsis of the stomach four
or five months post distal gastrectomy and would consider it abnormal if there was not. 134
With the reconstruction as Mr Starkey described, A/Prof Brown would not have expected Mrs Mulqueen to be tolerating the NJ tube feedings, feeling a lot better and keeping small amounts of food, eaten orally, down quite well in February 2009, as described in Dr Dinh’s letter to Dr Shea.’ She would only allow for improvement whilst the NJ tube was being used for nutrition, but would expect improvement when stopping the NJ tube and eating orally if the aberrant reconstruction was a shorter common channel.’ She believes there was an element of malabsorption as well as reduced intake from the poor gastric emptying and that Mrs Mulqucen was definitely eating less than she would have because of that. She conceded that pre-August 2008 Mrs Mulqueen was malnourished and that in a very short
period of time she had experienced. a rapid decline in weight, and that a 30 year history of

issues to do with vomiting and nausea would contribute to malnutrition,!*” She agreed with the comment made by Mr Evans in his report dated 10 September 20128 that ‘there remains some contradictory evidence in relation to the initial operation report and Dr Starkey’s subsequent findings, however the. whole clinical course and subsequent malnutrition would suggest that there may well have been an aberrant reconstruction at the
first operation highly likely’.'?
A/Prof Colin Russell was the final witness to give evidence at inquest. At the time of the operation on Mrs Mulqueen on 20 August’ 2008, he was a General Surgeon at Peninsula Health, a position held since 1992, He has since retired, in 2010. He had performed approximately 50 Roux-en-Y reconstructions, 20 to 30 of which were the same gastric procedure as that performed on Mrs Mulqueen.! He performed the gastric procedure due to there being no gastric outlet from the stomach into the duodenum, which was confirmed during an endoscopy he performed,'“!
His recollection of the gastric procedure on Mrs Mulqueen was fairly general. He did not
® and used his operation notes to
have a specific recollection of the actual operation, confirm that he used his usual technique when performing the operation. Even if he remembered the surgery he would go to the notes, as he considered it to be entirely appropriate.! His evidence was drawn, from his memory and working memory of what these types of surgeries involve, including his experience and reference to the specific medical notes, documents and diagrams.!4 He was the lead surgeon and Dr Yihua Xie assisted him by holding tissues of the way, retracting organs and performing checks and balances. A/Prof Russell believed that he would have done the sutures because he was listed
as the surgeon in the operation report, but cannot remember. He performed the mobilisation
of the bowel and gastrojejunal anastomosis, but may have supervised Dr Xie with the other

anastomosis, although does not have a firm recollection.“ He was ‘pretty certain’ he did the raising of the vascular pedicle and transection between the distal and proximal small bowel and had a very strong recollection that he did the majority of the operation, but conceded that it is possible that Dr Xie did the enteroanastomosis at the end.!©° He said that it could have been the first time he and Dr Xie worked together. He and Dr Xie would have performed approximately 500 or 600 operations, not all big necessarily, over the two years during the time they operated on Mrs Mulqueen.'®’ He could not remember specifically if checks and balances did occur during the operation, but said he established a technique with various checks and balances in it, and has no reason to believe it was different to that! His initial focus was the structure at the gastric outlet. Prior to the operation he was aware that there was an obstruction and there did not seem to be any lumen continuing into the duodenum. He conceded that the Roux-en-Y operation was not as common as it was in the 70s and 80s and that he may not have performed Roux-en-Y procedures commonly since the
early to mid 90s.!°
During the procedure he could feel fibrosis, build-wp of scar tissue and narrowing, compatible with vomiting and problems with gastric emptying. He determined that the most likely cause of the fibrosis was due to the ulceration and he had no reason to suspect anything else. Her small bowel on external inspection looked normal. If there was significant or severe disease in the small bowel it would have been visible with usually some external manifestation. The surgery was an orthodox treatment for Mrs Mulqueen’s diagnosis and all things going well, it should have, in time, led to a resolution of the signs and symptoms of that diagnosis.'”° On a continuum of least to most complex procedure, Mrs Mulqueen was at the lower end because there weren’t adhesions and there was not a lot of

A/Prof Russell drew two diagrams explaining his normal practice when performing a Rouxen-Y gastrectomy.!” First he has a general look to check for anything unexpected, which he notes in the operation report. There is no record of any abnormality in Mrs Mulqueen’s operation report. He then checks the small bowel is clear and normal, and assesses the blood supply to the small bowel, making sure the vascular arcade looks adequate. He then divides the stomach and duodenum, and removes this portion of stomach, ties all the blood vessels so there is no bleeding, and oversews both the duodenal stump and stomach with sutures so they do not leak.!”? He then looks for the DJ flexure, because it is the end of the duodenum and the fixed landmark for the start of the jejunum. He finds a suitable part of the jejunum and picks a spot which provides mobility and has blood supply, transects the jejunum and takes the distal part of the transected jejunum to the new gastric outlet. The appropriate spot to make the transection is based on the bowel’s mobility and being relatively close, usually approximately one to two feet maximum from the DJ flexure, where it is under no tension. The distal and proximal end are distinguishable due to the mesentry being divided to create a mobile piece of bowel, resulting in the distal end still having veins and arteries, and normal vessel all the way up to the end, creating a vascular pedicle, and the proximal end only having a narrow strip of mesentry, which make them look quite different.'”* The proximal end of the transected jejunum is then joined as an antacidum

A/Prof Russell can identify the proximal and distal parts of the transected bowel as they look quite different, due to the vascular pedicle, which is fashioned like a tongue and up to one foot long and three inches wide.’ He uses the vascular pedicle as a check and also reaffirms the parts by finding the DJ flexure.'” He completes two spot checks of the DJ
flexure, the first to ascertain that there was no small bowel problem and the second upon

running through it himself,'*!
Although in previous surgeries he has marked the distal portion of the transected bowel, due to bleeding issues he has not used it as a conventional way of identification. Instead, he refers back to the DJ flexure, which he described as ‘sort of tortuous’, but the other method.'® He stated that in a slim patient you can sce the DJ flexure, but that he also runs his hand along the bowel to identify it. Then, as a form of checks and balances, he always goes back and checks where all the anastomoses are, in collaboration with his assistant. He described it as a procedure that has to be done carefully which requires him to take note of
the steps and do them in order.

positioning it is difficult to tell ileum and jejunum apart, but that it was not critical for the purpose of his operation on Mrs Mulqueen because he was aiming to do the operation in the
upper part of the small bowel. !®8
In relation to whether he could have become confused and made a transection very close to the ileocecal valve, as described by Mr Starkey, A/Prof Russell said he would find it very hard to believe he could do that, especially with the presence of a knowledgeable assistant and using his technique of always referring back to the DJ flexure,'®? In relation to whether it was possible to pet confused and bring the wrong end up to the gastric outlet, he said that it is always possible to make a mistake, which is why he has checks and balances and why the DJ flexure is the reference point. Before he does anything with the ends, he checks back on each bit of bowel to see where it goes and what its origin is, when he checked at the end of Mrs Mulqueen’s operation it would have been visible. It would be relatively simple to correct and would just require taking down that anastomosis and redoing it in the proper place.’ Referring to the documentation and. operation report, A/Prof Russell stated that adhesions were not a feature of Mrs Mulqueen’s procedure, as they would be mentioned if they were significant. Further, no fistulas were mentioned in the operation notes and he did
not recall a fistula”!

He also could not be certain that he could identify the ileocecal valve in the photograph. !4 He agreed that there are not metres of small bowel in the photograph, but stated that it could be a metre because it is doubled back on itself at two points.

difficult to distinguish what is ileum and jejunum, that it will vary in people who have had operations and are suffering malnutrition and that you would have to go by the position of the small bowel. If it’s right beside the cecum it’s obviously going to be ileum. If it’s up near the DJ flexure it is going to be jejunum and somewhere in between there will be a change.!?> There was nothing inconsistent in the operation report of Dr Xie with the way
A/Prof Russell would generally perform the procedure. 196
A/Prof Russell supervised and made the decisions regarding Mrs Mulqueen’s post-operative management. He stated that being on TPN until 31 August 2008 was not typical, and that not every patient would be on TPN, but that she had commenced it prior to surgery because she had lost so much weight and had been unable to eat and drink for some time. The TPN was continued after surgery to take her over the period before she could start to eat again. !°” During the 25 September 2008 review Mrs Mulqueen had a complaint of left lower quadrant pain which he focused on. He also recalled her having diarrhoea, as reported by Dr Xie when he reviewed her in November 2008. Up to approximately three months after the reconstruction diarrhoea, especially initially, is not uncommon, as sometimes the gastrojejunal anastomosis takes time to function. He stated that usually it would keep the patient in hospital, so it wasn’t a major problem for Mrs Mulqueen.’*8 He would also expect reasonably consistent diarrhoea if the reconstruction was as A/Prof Brown suggested, with a short common channel, but felt that diarrhoea might not be the predominant symptom with Mr Starkey’s version of reconstruction; rather, nausea, loss of appetite and vomiting due to the antiperistaltic limb.’ The magnitude of the diarrhoea was not described at either
follow-up with Dr Xie.
Other than if there were adhesions, which would require the surgeon to look at every bit of bowel, where it goes, what joins with it and where it comes from, A/Prof Russell stated that he would hope that a surgeon would be able to map out the reconstruction and accurately describe it. He agreed with A/Prof Brown that he did not think Mrs Mulqueen would have left hospital if Mr Starkey’s version had occurred. He had given some thought to A/Prof
Brown’s alternative reconstruction and conceded that we have to accept that we can make

mistakes. However, going over his notes and recollection of what he normally did, he could not see how he would have brought the anastomosis in so low.?”° He finds it hard to believe that the anatomy would have allowed Mrs Mulqueen to go home at all, due to intractable vomiting, but agreed that if there was a short common channel that it could cause more severe diarrhoea than one would expect after the vagotomy.””' His reasons for believing that Mrs Mulqueen would have had intractable vomiting is because although something would go up the antiperistaltic limb, it does not go up very far because it is continuously
being pushed down.?”
He agreed that by 4 August 2009, Mrs Mulqueen was severely malnourished and that postoperatively from August 2008 she suffered bad problems with diarrhoea, as part of malabsorption, and that poorly digested food was entering the cecum which could cause diarrhoea. He agreed that if the reconstruction was as Mr Starkey suggested that he would expect that there would be an antiperistaltic effect from the blind limb.”™ He said there is no reason why nutrients shouldn’t be absorbed if material from the stomach is going into the blind limb, as Mr Starkey described, because it is not completely a blind end and there are
other secretions coming down?"
In relation to the diagram drawn by Dr Xie in the operation report,” A/Prof Russell stated that it is a diagrammatic representation and that the ‘upside-down V’ formation refers to the fact that a T-junction was made there. He disagreed that it is a representation of a transection with stitching, but conceded the diagram is confusing and clumsily drawn. The right side of the inverted ‘V’ is not a representation of stitching and could be looking at the portion which is a the blind end coming down and being sutured onto the main limb which goes down to
the ileocecal junction.”
A/Prof Russell felt that there were no problems during the operation and was happy at the end of it. There was nothing unusual that occurred during surgery to make it more
memorable than any other surgery he had conducted. Post-operatively, Mrs Mulqueen was

attending with a number symptoms. Although it did not cross his mind that the surgery was wrong, he felt that the side-effects of the surgery were worse than he had seen before. He did not relate that back to the possibility of aberrant surgery at the time, duc to her having a pre-operative history of 30 years with a lot of problems, including a long history of intermittent duodenal/peptic ulcer,” and because although he hoped the symptoms improve by three months it could go longer. He gave her medication to control her diarrhoea and referred her to a dietician to see if this could improve things. At no stage did he consider that there might have been a mistake in the way the surgery was performed, and expected that eventually she would get better.“ The only explanation he could offer for Mrs Mulqueen’s post-operative progress was the effect, or response, of the vagotomy.””” He said that if there was incontrovertible evidence that he made an error during surgery, he would have to accept
it and would have no difficulty doing so,71
He stated that gastroparesis is a symptom that may manifest as a result of post-vagotomy complications. There is denervation. The pyloris and gastric antrum is removed, which creates a spectrum of loss and change in motility in relation to two major functions, mixing and sorting of the food. This can cause symptoms including weight loss/not being able to
maintain weight, frequent and fluid diarrhoea and bloating”?
In relation to the seven matters A/Prof Brown identifies to reach her conclusion that there is an aberrant reconstruction, if Mrs Mulqueen had a significant response to the vagotomy diarrhoea could certainly be the result of a vagotomy and partial gastrectomy, and also indicative of A/Prof Brown’s alternative version of reconstruction. Hypoalbuminaemia is a sign of malabsorption not specific to any one cause. Iron deficiency is a fairly frequent problem after gastrectomy, and anaemia is related to iron deficiency. Profound loss of weight is not expected post-vagotomy but could occur with severe symptoms. The need for TPN to maintain nutrition is a further indication of malabsorption, and the liver function tests are in keeping with people who have malabsorptive procedures. Besides the diarrhoea, which is a symptom, all six are signs of malabsorption, which is unexpected in a post-
vagotomy patient. In relation to whether the signs and symptoms are more indicative of an

aberrant reconstruction or post-vagotomy symptomology, A/Prof Russcll stated that the symptoms that Mrs Mulqueen developed were obviously beyond what he expected. He thinks both are a possibility and cannot say equivocally 100 per cent that he did not make a
mistake in the reconstruction.”””
He agreed that during his operation, the bowel looked normal and in August 2009 it looked abnormal, but stated that his understanding is that they are acute rather than chronic changes, and the question was whether it was the drugs used to treat it that affected it, but the supposition was that maybe there was a leak or something like ischemic bowel, and the appearances were more acute.” Her ‘dramatic weight loss’ over the six weeks leading up to 6 August 2008 appeared to be acute, and progress notes from 6 August 2008 documented that she had ‘normal bowel movements’, which A/Prof Russell said suggested that diarrhoea was not one of the symptoms at that stage and that it did not seem that she had a presenting history of chronic diarrhoea. He agreed with A/Prof Brown that a vagotomy could cause poor gastric emptying and diarrhoea.” He conceded that Mrs Mulqueen’s weight loss from 40 kilograms pre-operation, gradually decreasing to never above 35,5 kilograms from April 2009, a pattern of her being unable to gain weight, was certainly the most profound he has seen post vagotomy and gastrectomy. It was his hope and intention that she would have been gaining weight by July 2009, as he expected and achieved in almost every case where he had done similar surgery, and he said that this is an abnormal case.’'* He said that the subjective evidence of Drs Ding and Evans seems to suggest that if there is some improvement ftom the insertion of a nasojejunal tube, that a problem has somehow becn bypassed, but noted that there are no weight measurements to substantiate this.”'® He agreed that on 25 September 2008 Dr Xie did have a real concern about ongoing symptoms and raised his concern as to what the cause of the problems may be, in which he indicated that it could possibly be a normal process from surgery. When questioned whether it is not rather strange that there doesn’t appear to be an arrangement for continued outpatient surgical review, A/Prof Russell said that he would have been surprised if further outpatient
appointments hadn’t been made, but that Mrs Mulqueen did not attend and may have chosen

to go elsewhere. She attended with Dr Xie on 20 November 2008 for surgical follow-up, a dietician on 24 November 2008 and was scheduled to appear on 8 December 2008 but did
not attend?!”
A/Prof Russell stated that if he was in the same position as Mr Starkey and observed what he thought was an abcrrant or unusual surgery, there is nothing technically difficult for him to check and re-check it, apart from the presence of adhesions which can come from operations. He agreed that as Mr Starkey is a qualified surgeon, he presumes there is no reason why he would not able to locate the anastomoses, and that interpreting the T-
intersection would be bread and butter material for a surgeon, if done properly.” 18
A/Prof Russell was aware that Dr Xie was involved in over 100 gastrectomy procedures and personally performed more than 50 gastrectomics and reconstructions in China prior to coming to Australia, which was fairly wide experience compared to another registrar that might be assisting him. For somebody with Dr Xie’s experience, the complexity of his role as a surgical assistant was below his education level and was something that A/Prof Russell was comfortable he could do as well as, if not better than, any surgical registrar.?'? He agreed with Dr Xie’s statements that had he noticed anything Dr Xie would have told him during the operation, and that is consistent with what he knows of Dr Xie and his working relationship with him. He also agreed with Dr Xie’s statement that he would have noticed excess redundant small bowel or excessive loops of small bowel if the reconstruction was performed with a short common channel.” If he was fixing an anastomosis within 20 cm of the ileocecal valve, there would be movement of the valve when the bowel is lifted for the purpose of the anastomosis and it would be obvious to the surgeon and anyone else
watching, and it should be obvious to the surgical assistant?!
Prior to this occasion, A/Prof Russell has never received a complaint and had only been in the Coroners Court on one other occasion, which resulted in a finding that was not adverse to his interests, He could not give the most likely cause or contributor to Mrs Mulqueen’s
death. He does not think Mr Starkey’s version is compatible, opined that A/Prof Brown’s is

more understandable given the circumstances, does not think there is really any evidence that Mrs Mulqueen had a fistula, and his hypothesis is that it was the effect of the gastrectomy and vagotomy. He placed the likelihood of a fistula causing or contributing to the death possibly lower than Mr Starkey’s reconstruction, but could not come down either way in relation to the effects of the gastrectomy and vagotomy and the alternative reconstruction as suggested by A/Prof Brown. He stated that he thinks he has to consider it as a possibility that both A/Prof Brown’s alternative reconstruction and his hypothesis are equal possibilities. In relation to whether he was in a position to say whether either of them takes it over into the realms of more likely than not, he answered “only... based on what I feel occurred at the operation was within my normal practice and also having the expertise
of Dr Xie”?
. A/Prof Russell acknowledged that regardless of how the surgery was performed, the
outcome for Mrs Mulqueen is not what he, or anyone else, would have wished for. He was very much aware of how Mrs Mulqueen and her family suffered over that time, and only wished the outcome had been very different. He commented that the Victorian Surgical Council needs to stress that surgeons keep checking their anatomical landmarks throughout
the operation and at the end.”
Written submissions

Mr James Fitzpatrick of counsel for the Mulqueen family submitted that the circumstances surrounding Mrs Mulqueen’s death included an inadvertently aberrant surgical reconstruction by A/Prof Russell and/or Mr Xie during the performance of Roux-en-Y surgery on 20 August 2008, which played a key role in a chain of events that lead to Mrs
Mulqueen’s death.”
Mr Fitzpatrick submitted that the key evidence supporting this conclusion was: a) The direct observations and careful investigation by Mr Starkey on 9 August 2009; b) The photographic evidence of Mr Starkey;
c) The opinion of A/Prof Brown that what Mr Starkey said he saw is most likely to
reflect what happened (after she saw his photos and during her evidence),

89, Mr Ben thle of counsel for A/Prof Russell made the following submissions:
a)
b)
That the diagnosis in 2008 of gastric outlet obstruction was straightforward. The surgical treatment, if correctly performed should have allowed an alleviation of Mrs Mulqucen’s symptoms, but it did not. No other known medical problem can explain
her failure to recover and put on weight apart from the prospect of aberrant surgery;
That a small intestine that they submit was subject to the aberrant surgery is so closely connected to the area found to be showing signs of ischemia at laparotomy
that it is wholly unlikely to be pure coincidence;
The fact that misconstructions of Roux-en-Y whilst rare, occur and are reported in
the scientific literature;
The radiological opinion evidence of Prof Ptasznik that a large amount of small
bowel was not opacified on the gastrografin studies; and
The opinions of A/Prof Brown, Mr Starkey and Mr Peter Evans that the post-surgical course of severe malnourishment, diarrhoea and trouble with gastric emptying and stomach distension are consistent with some of form of aberrant reconstruction.””°
The reconfiguration as contemplated by the Roux-en-Y and distal gastrectomy is as described by A/Prof Russell and Mr Xie, and that evidence tending toward any contrary view is not supported by the objective clinical evidence, nor is it of such a
quality so as to satisfy the Briginshaw”*’ standard;
The allegations regarding an aberrant reconstruction are grave, and the evidence must stand up to the most careful and rigorous scrutiny before it can be accepted as
proof of such allegations;
The Court has not benefited from a complete longitudinal examination of Mrs Mulqueen’s medical notes, and results of other clinical examinations which were performed prior to her surgery in August 2008, and only in light of such a complete examination could the Court be fully satisfied as to the precise reconstruction of her
anatomy;

The combined professional experience of A/Prof Russel and Mr Xie must be
compared to that of other witnesses;
The evidence is not of a sufficient nature to permit the finding that A/Prof Russell’s operation was performed incorrectly. The vast majority of available evidence, including the objective clinical evidence suggests it was performed correctly. This is suggestive that Mrs Mulqueen’s ultimate demise was brought about by some other undiagnosed and unrecognised pathology, or idiosyncratic post-vagotomy symptoms;
It is impossible to reconcile the observations and opinions of A/Prof Brown, Dr Ptasznik and Dr Andrews in relation to the length of small bowel ‘in circuit’ in the
gastrografin study, with Mr Starkey’s hypothesis of it being 40 centimetres in length;
It is impossible to reconcile the observations and opinions of A/Prof Brown, Dr Ptasznik and Dr Andrews with Mr Starkey’s hypothesis in relation to the section of bowel immediately distal to the site of gastric anastomosis being jejunal rather than ileum;
The absence of any anti-peristaltic movement being noted by the radiologist who
performed the gastrografin tends against establishing an aberrant reconstruction;
There is no way to test Mr Starkey’s theory. The photos he took are inadequate, in the absence of his narrating what they depict, to assess his interpretation of how Mrs Mulqueen’s anatomy was configured. Furthermore, the forensic pathologist was not equipped with sufficient skill or experience to conduct a thorough and accurate
examination of Mrs Mulqueen’s smal] intestine.
Mr Starkey’s refusal to accept that he could, in any significantly material way, be in error is significant in assessing the weight that should attach to his evidence, and the caution with which it ought to be approached. This is especially so when there is an irreconcilable description in his post-operative note and subsequent statement to the
Court, which described Mrs Mulqueen’s bowel as necrotic;
The evidence would not support a finding that the anatomical reconstruction (even if as opined by Mr Starkey) would have caused Mrs Mulqueen’s death. At worst, such would be a background factor which was, on all the evidence available reversible and not the cause of her sudden deterioration in August 2009. The cause of her death
is, and will remain, relatively unknown.

- Mr Ihle submitted that the Court consider making a recommendation to the responsible body to consider implementing a process of documenting, by way of photographs or video, and/or independent secondary corroboration, by a relevantly qualified professional, of any alleged observations of evidence of aberrant surgical reconstructions. He also submitted that the Court consider making a comment or recommendation to the Victorian Institute of Forensic Medicine to investigate and implement procedures for the involvement of suitably qualified
specialist surgeons in cases involving alleged aberrant performance of surgery.?7®
FINDINGS
91.‘ [have been greatly assisted by written submissions from Mr Fitzpatrick of counsel for the Mulqueen family and Mr Ihle of counsel for A/Prof Russell. Not all submissions are specifically referred to in my Finding, however all submissions have received my careful consideration. Submissions which have a causal or temporal link to circumstances surrounding Mrs Mulqueen’s death, notably, whether an inadvertently aberrant surgical reconstruction was performed during the course of the distal gastrectomy and vagotomy
procedures undertaken at Frankston Community Hospital on 20 August 2008, were of
particular assistance.
Mr Starkey
- Mr Starkey was an impressive witness whose evidence was compelling. The manner in
which he detailed his observations, combined with the diagrams contemporaneously drafted
by him in addition to surgical photographs and communication with a senior colleague lead me to believe that it is more likely than not that his observations were carefully made,
accurately recorded and reflective of the aberrant reconstruction as detailed by him.
- A/Prof Brown, Dr Burke and A/Prof Russell acknowledge a surgeon in the position of Mr Starkey was perfectly placed to make the observations; in particular identifying the anastomoses, which A/Prof Brown described as a fundamentally basic skill for a surgeon of
some expertise.
- Mr Starkey had no preconceived consideration of an aberrant reconstruction. He was observing a procedure, performed by a surgeon, not previously known to him. He was
alarmed initially by the short length of bowel which led him to undertake a careful,

deliberate and thorough investigation. He fully understood the gravity of his findings; they
were not lost on him.
The impressive manner in which he gave evidence was reflective and indeed highlighted his professionalism, and attention to detail. He meticulously drew a contemporaneous diagram of his observations, took surgical photographs and telephoned a senior colleague to convey
his findings.
A/Prof Brown was equally impressed by Mr Starkey’s evidence, confidently identifying the anastomoses by reference to his surgical photographs. She could offer no basis to challenge his findings, albeit she conceded that there is a problem relying on the photographs ‘because she has to rely on Mr Starkey’s description as being correct to arrive at a conclusion that his description is correct’.””’ She gave evidence that she was very confident that at laparotomy she would be able to determine whether it was an aberrant reconstruction or shortened common channel, and on this basis, A/Prof Brown accepted that Mr Starkey is ‘probably
correct’ as he was there, took photographs and assessed it.
It became apparent to Mr Starkey that sadly, Mrs Mulqueen could not be saved and he devoted a significant amount of time to ensure that these observations and measurements were accurate, in particular following the bowel along and dissecting out the adhesions to
make sure he appreciated the anatomy correetly.”*"
Mr Starkey is a highly qualified and skilled surgeon. When he performed his laparotomy he discovered that ‘the distance between the enteroenterostomy and ileocecal junction was approximately 20 centimetres’. Mr Starkey stated that the first thing that struck him was the short distance between the gastroenterostomy, enteroenterostomy and ileocecal junction.
The second was that the distal ileum was connected to the side of the ileum so that the bowel was joined on the side and you could see it coming into the side, creating a pronounced intersection, whereas he described that usually in a normal situation the part of the bowel going up to the stomach is in continuity with the ileocecal junction.?” He described
following the bowel.along carefully with his hands. He gave the following evidence:

Linvestigated, so T moved — and that just means holding the bowel between your hands and following it along ... carefully and so you can — starting at this end and finding this anatomy, and then starting at the DJ flexure and moving distally. If you start at the DJ flexure you expect to find the roux-en-Y quite close to the DJ flexure. Whereas in this case there were multiple loops of
bowel, most of the small bowel, prior to finding the anastomosis.
He indicated that he started at the DJ flexure which was easily identifiable and moved down from there.’ On that same day Mr Starkey drew a picture of Mrs Mulquecn’s small intestine", He drew this diagram on the back of his operation report. He also made note in the clinical notes and drew a further similar diagram. Mr Starkey came to the view that the clinical health of Mrs Mulqueen’s bowel was irretricvable and he determined that there was no chance of survival. The purpose of the laparotomy was a last effort, to determine if Mrs Mulqueen’s medical situation could be salvaged. Unfortunately it could not be.”> During this process Mr Starkey took the photographs that are exhibited before the Court. He also indicated that he unscrubbed and spoke on the telephone to the Head of the Unit, Mr Blamey.
Mr Starkey was very clear that he did not rush anything during the examination and that it was a very careful examination.*® He is an entirely independent witness and the consequence of
what he saw was not lost on him at the time.
Possibility And Impact Of An Aberrant Reconstruction
Whilst the focus of the inquest has not been on the intervening medical management over the 12 months prior to Mrs Mulqueen’s death, there has been significant commentary on it.
In her statement, Mrs Mulqueen’s daughter highlighted the courage displayed and suffering endured by her mother in the 12 months prior to her death, Whilst various medical practitioners expressed surprise that Mrs Mulqueen could have survived, if Mr Starkey’s observations were correct none could refute the possibility. [ accept Mr Starkey’s evidence that no one knows the answer, having never previously seen a surgical procedure identified
by him.

The point needs to be made that no witness in the case had seen surgery like that which Mr Starkey says he found. It may be that it is surprising to them that when they extrapolated mentally and hypothesized as to how Mrs Mulqueen lived on, if she did, that she didn’t

whole clinical course and subsequent malnutrition would suggest that there may well have been an aberrant reconstruction at the first operation highly likely.’ A/Prof Brown shared
Mr Evans views.
I further endorse the following submission of counsel for the family of Mrs Mulqueen:
Like all witnesses Mr Starkey had never seen an aberrant piece of surgery like he found.
Therefore it is very difficult for any witness to estimate how Mrs Mulqueen would have fared
nutritionally in that circumstance.”
When asked however, as to the likely consequences for an individual experiencing that aberrant
surgery Mr Starkey said:
I think the first issue would be malabsorption, so in other words, the inability to absorb sufficient nutrients from ... her diet. And that’s because of the short part of the bowel, which is so called in circuit;
The second thing is that if you get food that’s poorly digested that enters the caecum and enters the large bowel, that tends to cause diarrhoea, so you would expect diarrhoea that would be difficult to
treat.
And the third thing, again we’ ve spoken a bit about this, is that the bowel that’s antiperisteltic going up to the stomach would in effect be working against the stomach in terms of its emptying and that would make it more difficult for the stomach to empty, so you would expect the stomach to become enlarged and have, you know, poor gastric .., But I think, as you point out, it’s important to say that, you know, no one has really seen cases like this so it’s hard for me to...give any experience of
that, 24°

Further, in respect to the effect of the aberrant surgery, the evidence referred to Mrs Mulqueen on 6 August 2009 having a weight of 33 kilos and being approximately 155 to 158 om tall.4!

thought there was no doubt that if you are severely malnourished, ‘getting a subsequent illness is a significant, you know it’s a significant risk for poor healing and ... would hasten demise — sorry — progression? Possibly. As I said before T think malnutrition is associated with a large
degree of immune-compromise.””
Mr Starkey stated:
I’m saying she developed. ischemia which was the reason — or developed profound sepsis and abdominal pain, and that’s what made me do the operation, And I found evidence of the
previous surgery, but the cause of her death, was I think a gut ischemia?
A/Prof Wendy Brown was a surgical expert called on behalf of the Court to assist the inquest.
She gave evidence that in terms of the task for Mr Starkey, of locating the anastomoses visually and then with his hands, that’s something that she would expect a surgeon such as herself and/or Mr Starkey to have very little difficulty in doing. 244 T endorse this evidence, The importance of this point is that for the surgical reconstruction to be significantly different from what Mr Starkey says he carefully observed, it would involve him making fundamental errors
in his following of the bowel and his visual observations.
Mr Starkey was acutely aware, once he discovered the aberrant reconstruction, of the importance of reporting what he found. The gravity of the situation was not lost on him. He used his fundamental surgical skills and experience to conduct a slow, careful and thorough examination following the bowel along and dissecting out the adhesions to make sure that he appreciated the anatomy correctly. Landmarks that he searched for were basic for a surgeon of his experience.
Mr Starkey’s evidence and method of investigating the small bowel was described in detail

Starkey would be capable of following the bowel,” The recognition of the opportunity for a skilled surgeon such as Mr Starkey to actually do the manual and visual inspection that he went through found A/Prof Brown in agreement that it was an unusual opportunity to visualise this in another person rather than relying on investigations and other surrounding signs and symptoms.” A/Prof Brown agreed that it was likely to be a strong indication as to how the anatomy actually was on the day that Mr Starkey saw it. She did however apply the natural caveat that sometimes in an emergency situation “with a very unwell patient we do things in a hurry and the measurements may not be as accurate.’”“* She was not suggesting Mr Starkey did
this and his evidence appears to be to the contrary,”
A/Prof Russell was a general surgeon who performed the procedure on Mrs Mulqueen on the 20 August 2008. At that time he was general surgeon at Peninsula Health. In my view A/Prof Russell endeavoured to assist the court however was, not surprisingly in light of the length of intervening time, unable to recall the specific procedure. His evidence was drawn from his memory and working notes. He was the lead surgeon assisted by Dr Xie.”*° It was possibly the first occasion he worked with Dr Xie. Dr Xie assisted him by holding tissues away, retracting organs and performing checks and balances. A/Prof Russell conceded that the Roux-en-Y operation was not as common as it was in the 70s and 80s and that he may not have performed Roux-en-Y procedures commonly since the early to mid 90s.’ He believed he would have performed the suturing, because he was listed as the surgeon in the operation report, but could not remember. He believed he performed the mobilisation of the bowel and gastrojejunal anastomosis, but may have supervised Dr Xie with the other

A/Prof Russell was ‘pretty certain’ he did the raising of the vascular pedicle and transection between the distal and proximal small bowel, and had a very strong recollection he
performed the majority of the operation, however conceded the possibility that Dr Xie

had marked the distal portion of the transacted bowel, due to bleeding issues he has not used
it as a conventional way of identification.
- A/Prof Russell acknowledged that by.4 August 2009 Mrs Mulqueen was severely malnourished and, post gastrectomy and vagotomy, suffered bad problems with diarrhoea due to malabsorption. If the reconstruction was as Mr Starkey suggested A/Prof Russell would expect that it would be an anti-peristaltic effect on the blind limb. He stated “there is no reason why nutrients shouldn’t be absorbed if material from the stomach is going into the blind limb, as Mr Starkey described, because it is not completely a blind end and there are other secretions coming down.” He felt there were no problems during the operation and was happy at the end of it. Although it never crossed his mind that the surgery was wrong, he acknowledged that the side effects suffered by Mrs Mulqueen following the surgery were the worst that he has ever seen. At no stage did he consider the possibility of an error in his surgical procedure, and expected that Mrs Mulqueen would eventually improve. His only explanation for Mrs Mulqueen’s post operative progress was the effect or response of the vagotomy. However he acknowledged that if there was incontrovertible evidence that he made an error during surgery he would have to accept it, and would have no difficulty doing
SO.
- In light of A/Prof Brown’s alternative version of reconstruction, and noting that the symptoms suffered by Mrs Mulqucen were obviously beyond his expectation A/Prof Russell could not equivocally refute having made a mistake in the reconstruction. He gave evidence that he thinks he has to consider it as a possibility that both A/Prof Brown’s alternative reconstruction and his hypothesis are equal possibilities. In relation to whether he was in a position to say whether either of them takes it over into the realms of more likely than not, he answered “only... based on what I feel occurred at the operation was within my normal
practice and also having the expertise of Dr Xie”.”*°

Tt was A/Prof Russell’s expectation that Mrs Mulqueen would have being gaining weight by July 2009, as was expected and achieved in almost every case where he had done similar surgery, and he acknowledged that this was an abnormal case. He agreed that on the 25 September 2008 Dr Xie had a real concern about ongoing symptoms and raised his concern as to what the cause of the problems may be in which he indicated that it could possibly be a
normal process from the surgery.
To his credit, A/Prof Russell acknowledged that were he in the same position as Mr Starkey, having observed what he believed was aberrant and unusual surgery, there was nothing technically difficult for him to check and re-check it, apart from the presence of adhesions which can come from operations. A/Prof Russell conceded that as Mr Starkey is a qualified surgeon, he presumes there is no reason why he would not be able to locate the anastomoses, and that interpreting the T-intersection would be “bread and butter” material for a surgeon,
if done properly.
The Cause Of Mrs Mulqueen’s Deterioration Shortly Prior To Mr Starkey’s Procedure In August 2009
I am satisfied that the observations of Mr Starkey are correct, in respect of the aberrant reconstruction performed by A/Prof Russell as head surgeon during the distal gastrectomy and vagotomy procedure performed on 20 August 2008. The malabsorption and clinical deterioration in Mrs Mulqueen’s health in the 12 months post gastrectomy and vagotomy would appear to be directly related to the aberrant reconstruction. However, the ultimate cause of Mrs Mulqueen’s bowel ischaemia cannot be ascertained. I endorse the evidence of
Mr Starkey:
I’m saying she developed ischaemia which was the reason — or developed profound sepsis and abdominal pain, and that’s what made me do the operation. And I found evidence of the previous surgery, but the cause of her death was, | think, a gut ischaemia... I can’t see what
the final trigger or the final factor was. It’s not clear to me.756
T endorse the evidence of Mr Starkey, concurring with the evidence of Dr Burke, that:
256 Trquest transcript 184.

121,
although you can think of a range of possibilities, there is nothing specific which you can put your finger on as being the trigger or a cause, or the significant onset of her deterioration in
the days before death or the development of ischaemia of the gut.’ -
Accordingly, I endorse the submission of counsel for A/Prof Russell that the evidence does not support a finding that the anatomical reconstruction, even if as opined by Mr Starkey, would have caused Mrs Mulqueen’s death. Unfortunately and tragically, the cause of Mrs Mulqueen’s rapid and significant onset of deterioration and subsequent death is, and will remain, relatively unknown. It will also unfortunately remain unknown if identification of the aberrant reconstruction, and subsequent reversal, prior to Mrs Mulqueens rapid and
significant onset of deterioration, would have ultimately prevented her death.
Lam satisfied, having considered all of the evidence before me, that no further investigation is required.
The evidence satisfics me that the medical management and care provided by Jessie McPherson Private Hospital was reasonable and appropriate in the circumstances, having regard to the complexities involved. The evidence does not support a conclusion that the
medical care or management caused or contributed to Mrs Mulqueen’s decline or death.
T find that Mrs Mary Mulqueen died on 9 August 2009 and that the cause of her death is I(a)
small bowel ischaemia; and (2) distal gastrectomy.
RECOMMENDATIONS
Pursuant to section 72(2) of the Coroners Act 2008, I make the following recommendation(s)
connected with the death:
That the Royal Australasian College of Surgeons consider implementing a process of documenting, by way of photographs or video, and/or independent secondary corroboration (by a relevantly qualified professional) of any alleged observations of evidence of aberrant
surgical reconstructions.
That the Victorian Surgical Consultative Council educate Surgical Registrars and Surgeons on the importance of checking anatomical landmarks throughout and during the final stage
of a Roux-en-Y procedure.
