Abstract
Obesity can increase the risk of postoperative complications. Despite increased demand for patients living with obesity to lose weight prior to common surgical procedures, the impact of intentional weight loss on surgical outcomes is largely unknown. We aimed to conduct a pilot study to assess the feasibility of a full-scale randomised controlled trial (RCT) to examine the effect of preoperative dietitian-led Very Low Calorie Diet (VLCD) Clinic on surgical outcomes in gynaecology and general surgeries. Between August 2021 and January 2023, a convenience sample of adults living with obesity (BMI ≥ 30 kg/m2) awaiting gynaecology, laparoscopic cholecystectomy and ventral hernia repair procedures were randomised to dietitian-led VLCD (800-1000 kcal using meal replacements and allowed foods), or control (no dietary intervention), 2-12 weeks preoperatively. Primary outcome was feasibility (recruitment, adherence, safety, attendance, acceptability and quality of life (QoL)). Secondary outcomes were anthropometry and 30-d postoperative outcomes. Outcomes were analysed as intention-to-treat. Fifty-one participants were recruited (n 23 VLCD, n 28 control), mean 48 (sd 13) years, 86 % female, and mean BMI 35·8 (sd 4·6) kg/m2. Recruitment was disrupted by COVID-19, but other thresholds for feasibility were met for VLCD group: high adherence without unfavourable body composition change, high acceptability, improved pre/post QoL (22·1 ± 15 points, < 0·001), with greater reductions in weight (-5·5 kg VLCD v. -0·9 kg control, P < 0·05) waist circumference (-6·6 cm VLCD v. +0·6 control, P < 0·05) and fewer 30-d complications (n 4/21) than controls (n 8/22) (P > 0·05). The RCT study design was deemed feasible in a public hospital setting. The dietitian-led VLCD resulted in significant weight loss and waist circumference reduction compared with a control group, without unfavourable body composition change and improved QoL.

Abstract
BACKGROUND Despite a lack of evidence that intentional weight loss reduces the risk of postoperative complications, adults with obesity are commonly asked to lose weight before elective surgery. We hypothesized that patients undertaking dietitian-led preoperative, very low calorie diet treatment could reduce perioperative surgery risks, as per validated risk scoring systems. The purpose of this study was to measure the impact of a dietitian-led preoperative very low calorie diet clinic on the American Society of Anesthesiologists physical status scores and National Surgical Quality Improvement Program Surgical Risk Calculator scores for patients with obesity awaiting non-bariatric elective surgery. METHODS This retrospective cohort study included patients referred to the preoperative dietitian-led very low calorie diet clinic before elective surgical procedures over a 2-year-9-month period. The dietitian prescribed individualized, very low calorie diet-based treatment. Primary outcomes were changes in the American Society of Anesthesiologists and Surgical Risk Calculator scores from pretreatment until surgery. RESULTS A total of 141 eligible participants (48 ± 13.4 years, 76% women, body mass index 41.7 ± 6.3 kg/m2) demonstrated clinically significant weight loss (mean 7.1 ± 6.1kg, 5.2% body weight, P < .001). Median treatment duration was 13 weeks (interquartile range 6.2-19.2 weeks). Five participants (3.5%) avoided surgery due to weight loss-related improvements in their condition. American Society of Anesthesiologists scores improved for 16% (n = 22/141) of participants. Overall, the median surgical risk calculator estimated risk of 'serious' and 'any' postoperative complication reduced from 4.8% to 3.9% (P < .001) and 6% to 5.1% (P < .001), respectively. Reduction in all Surgical Risk Calculator scores occurred, including surgical site infection, re-admission, and cardiac events (P < .05). CONCLUSION The dietitian-led preoperative, very low calorie diet clinic improved American Society of Anesthesiologists and Surgical Risk Calculator scores for non-bariatric elective surgery patients with obesity. Randomized controlled trials comparing this approach with a control group are warranted.

Abstract
Emphysematous gastritis is a rare surgical condition. Although there is a lack of a common definition, the key features of its presentation include gastric emphysema on imaging and the presence of gas-forming organisms in the gastric mucosa. In this study, we report the case of an 80-year-old Caucasian male who presented with abdominal pain; a computed tomography scan demonstrated gastric emphysema (intra-mural air within the stomach). After upper gastrointestinal endoscopy excluded gross perforation, ulcer, and malignancy, the patient recovered to baseline with conservative management consisting of gastric rest (nil by mouth and nasogastric tube decompression), intravenous antibiotics, and intravenous proton pump inhibitor. Given the wide pathogenic mechanisms for gastric emphysema, we recommend a conservative but cautious approach if the patient does not demonstrate clinical features of hemodynamic instability, sepsis, and peritonitis.

Abstract
BACKGROUND Emergency colorectal surgery tends to be associated with poorer outcomes compared to elective colorectal surgery. This study assessed the morbidity and mortality in patients undergoing emergency and elective colorectal resection in two metropolitan hospitals. METHODS Patients were identified retrospectively from two institutions between April 2018 and July 2020. Baseline, operative and postoperative parameters were collected for comparative analysis between emergency and elective surgery groups. A binary logistic regression was performed to identify independent predictors of postoperative complications. RESULTS During the study period, 454 patients underwent colorectal resection, 135 were emergency cases (29.74%) and 319 were elective cases (70.26%). Compared with elective resections, patients undergoing emergency resections were observed to have a higher American Society of Anesthesiologists (ASA) score of III to IV (53.33% vs. 38.56%) (P = 0.004). The mortality rate was similar between the emergency and elective group (1.48% vs. 0.63%, P = 0.369). The overall complication rate was higher in patients undergoing emergency resections (64.44% vs. 36.68%, P < 0.001), but the major complication rate was similar between groups (12.59% vs. 10.34%, P = 0.484). Independent predictors for postoperative complications included emergency surgery (Odds Ratio (OR) 2.77, 95% Confidence Interval (CI): 1.66 to 4.61) and an ASA Score of III to IV (OR 2.87, 95% CI: 1.84 to 4.47). CONCLUSION The overall complication rate was higher in patients undergoing emergency colorectal resection, however, rates of major complications and mortality were similar between groups. Higher complication rates reflect advanced disease pathology in patients who are more comorbid.

Abstract
Background: The implementation of the acute surgical unit (ASU) model has been demonstrated to improve care outcomes for the emergency general surgery patient in comparison to the traditional "on call" model. Currently, only few studies have evaluated surgical outcomes of the ASU model in patients with acute biliary pathologies. This is the first comparative study of two different emergency surgery structures in the acute management of patients with acute cholecystitis and biliary colic. Methods: A retrospective review of patients who underwent emergency cholecystectomy for acute cholecystitis and biliary colic at two tertiary hospitals between April 2018 and March 2019 was conducted. Primary outcomes included length of hospital stay, time from admission to definitive surgery, and postoperative complications. Secondary outcomes include proportion of cases performed during daylight hours, length of operating time, rate of conversion to open cholecystectomy, and consultant surgeon involvement. Results: A total of 339 patients presented with acute biliary symptoms and were managed operatively. Univariate analysis identified a shorter mean time to surgery in the traditional group compared to the ASU group (29.2 hours versus 43.1 hours; P < .001). There was no difference in mean length of stay, operation duration between models, and postoperative complication rates between groups, with the majority of surgeries performed during daylight hours. The ASU group had a greater proportion of consultant-led cases (48.2% versus 2.5%, P < .001) compared to the traditional group. Conclusion: Patients with acute biliary pathology requiring laparoscopic cholecystectomy achieve equivalent surgical outcomes irrespective of the model of acute surgical care.

Abstract
This systematic review summarises the literature regarding the impact of preoperative dietary interventions on non-bariatric surgery outcomes for patients with excess weight/obesity, a known risk factor for poor surgical outcomes. Four electronic databases were searched for non-bariatric surgery studies that evaluated the surgical outcomes of a preoperative diet that focused on weight/fat loss or improvement of liver steatosis. Meta-analysis was unfeasible due to the extreme heterogeneity of variables. Fourteen studies, including five randomised controlled trials, were selected. Laparoscopic cholecystectomy, hernia repair, and liver resection were most studied. Diet-induced weight loss ranged from 1.4 kg to 25 kg. Preoperative very low calorie diet (≤800 kcal) or low calorie diet (≤900 kcal) for one to three weeks resulted in: reduction in blood loss for two liver resection and one gastrectomy study (-27 to -411 mL, p < 0.05), and for laparoscopic cholecystectomy, reduction of six minutes in operating time (p < 0.05) and reduced difficulty of aspects of procedure (p < 0.05). There was no difference in length of stay (n = 7 studies). Preoperative ≤ 900 kcal diets for one to three weeks could improve surgical outcomes for laparoscopic cholecystectomy, liver resection, and gastrectomy. Multiple randomised controlled trials with common surgical outcomes are required to establish impact on other surgeries.

Abstract
A primiparous female developed acute large bowel obstruction Day 1 post lower segment Caesarean section. Initially presumed to be post-operative ileus, increasing abdominal pain and distension over the next 24 h prompted a surgical consult. Computed tomography imaging demonstrated an abrupt transition point of the large bowel behind a polymyomatous uterus. Although this case resolved with vigorous patient mobilization, literature review reveals previous cases resolving only after intraoperative mobilization of the uterus. It is distinct from ileus as bowel sounds are present, onset is abrupt, progression is rapid and mobilization of the uterus causes immediate resolution. This condition is likely to be more common than the literature would suggest, its scarcity partially due to the reluctance to image young females especially during pregnancy.

Abstract
BACKGROUND In Australia, there has been a shift from the traditional 'on-call' surgical model to the 'acute surgical unit' (ASU) model to improve outcomes in acute general surgery. Using emergency appendicectomy as a standardized procedure, we aimed to identify the different patterns of care between these on-call structures by comparing two metropolitan district hospitals; one that employs a traditional on-call model and the other, which employ the ASU model. METHODS Data on consecutive patients undergoing emergency appendectomies at the two hospitals (traditional and ASU model) between July 2018 and December 2018 were retrieved for retrospective review. Patient factors, preoperative factors, operative factors and post-operative outcomes were collected and tabulated for comparative analysis between the traditional versus ASU model of care. RESULTS Univariate analysis demonstrated that there were a greater proportion of consultant-led cases (P < 0.001), a shorter time to theatre (P = 0.047) and a greater number of out-of-hours operations (P < 0.001) in the ASU model compared to the traditional model. A larger proportion of patients from the traditional model underwent a computed tomography scan as part of their diagnostic workup compared to the ASU model (P < 0.001). There was no difference in negative appendicectomy rates, intraoperative conversion rates, post-operative complication rates or mean lengths of hospital stay between the two on-call models. CONCLUSION The ASU and traditional on-call model appears to achieve equivalent care outcomes for patients with acute appendicitis.

Abstract
BACKGROUND Acute Appendicitis is the most common surgical presentation within Australia. Despite the increasing use of radiological investigations to aid clinical diagnosis, many appendectomies result in a histologically normal appendix. This study examines the histological negative appendicectomy rate (NAR) in a metropolitan hospital and determine factors associated with a negative appendicectomy (NA). METHODS Patients who underwent emergency appendicectomy for suspected acute appendicitis at Logan Hospital, Australia, between February 2016 and March 2019 inclusive were included. Clinicopathologic and imaging variables were analysed for associations with NA. RESULTS A total of 1241 patients underwent emergency appendicectomy of which 121 patients (9.8%) had a NA. The NAR for clinical diagnosis alone (no imaging) was 9.9%, 14.5% for ultrasonography alone and computed tomography scan alone was 4.9%. Univariate analysis revealed age <27 years (P < 0.001), absence of hypertension (P = 0.008), symptoms >48 hours (P < 0.001), absence of leucocytosis (P < 0.001), undergoing ultrasonography only (P < 0.001), undergoing computed tomography scan only (P < 0.001), macroscopically normal appendix (P < 0.001) and time to operation >24 hours (P < 0.001) were associated with NA. Multivariate analysis identified symptoms >48 h at presentation (odds ratio (OR) 1.98, 95% confidence interval (CI) 1.20-3.24; P = 0.007), absence of leucocytosis (OR 2.41, 95% CI 1.52-3.81; P < 0.001) and macroscopically normal appendix (OR 5.70, 95% CI 3.49-9.33; P < 0.001) to be associated with a NA. CONCLUSION The NAR reported is lowest in an Australian institution. The identified predictors of NA will be useful in identifying patients who would truly benefit from an appendicectomy versus those would have a higher rate of NA who may be suitable to be treated non-operatively to be spared the unnecessary morbidity of surgery.

Abstract
BACKGROUND Strangulated and obstructed ventral hernias require emergent repair to mitigate the risk of life-threatening complications. Emergency ventral hernia repairs are associated with a higher rate of surgical complications and recurrence compared to elective repairs. The purpose of this study was to explore the impact of patient factors, hernia and operative characteristics on post-operative outcomes in patients requiring emergency ventral hernia repairs. METHODS Data were collected from a prospectively held database on 86 consecutive patients undergoing emergency ventral hernia repairs between January 2016 and January 2019 at Logan Hospital. Patient, hernia and operative characteristics were collected for reporting and analysis. RESULTS Of the 86 patients, 29 (34%) developed a surgical complication, of which 17 patients (59%) had surgical site infections. We identified obesity (P = 0.017), history of smoking (P = 0.008), American Society of Anesthesiologists class of III-IV (P = 0.008), hernia defect size ≥3 cm (P = 0.048) and concomitant small bowel resection (P = 0.028) to be associated with post-operative surgical complication. Multivariate analysis identified smoking (P = 0.005) and concomitant small bowel resection (P = 0.026) as independent predictors for developing surgical complications. Seven patients (8%) recurred at a median of 221 days. Incisional hernias (P = 0.001), recurrent hernias (P < 0.001), greater than one defect (P < 0.001) and bowel involvement (P = 0.049) were associated with higher rates of hernia recurrence. CONCLUSION Patient factors significantly influence outcomes in the emergency setting. Given that this is not modifiable at the time of surgery, greater emphasis needs to be placed on optimizing the physical and behavioural factors of patients with early symptomatic hernias for an elective repair.

Abstract
Acute diverticulitis is an emergency surgical condition that is commonly managed via an acute surgical unit model. Operative surgery is indicated in selected situations including generalized peritonitis or fistulous disease; however, limited data exist on how borderline patients potentially needing surgery may be salvaged by close clinical management with modern interventional techniques. The aims of the study were to identify the operative surgery rates in acute diverticulitis and predictors for identifying patients with complicated diverticulitis. Retrospective data collection was performed on a prospectively held database at a high-volume acute surgical unit at Logan Hospital, Queensland. Patient demographic data, disease-related factors, and treatment-related factors were collected for reporting and analysis. Over three years (2016-2018), 201 patients (64%) were admitted with uncomplicated diverticulitis and 113 patients (36%) with complicated diverticulitis. An observable downward trend was noted in the number of yearly admissions for uncomplicated diverticulitis. Complicated diverticulitis was associated with male gender (P = 0.039), increased length of hospital stay (P < 0.001), temperature ≥37.5 (P = 0.025), increased white cell count (P < 0.001), and elevated C-reactive protein (P < 0.001). Twelve patients (11%) with complicated diverticulitis initially failed conservative management. Seven patients (6%) underwent a definitive Hartmann's procedure, and 5 patients (4%) underwent percutaneous drainage of abscesses. Acute diverticulitis can be safely managed nonoperatively by medical therapy and percutaneous drainage of abscesses, with surgery reserved for patients with complicated diverticulitis with sepsis or peritonitis.

Abstract
BACKGROUND Pancreatitis secondary to hypertriglyceridaemia is rare, accounting for less than 5% of pancreatitis presentations. We reviewed our institutional experience with triglyceridaemia induced acute pancreatitis to report the clinical presentation, patient demographics and clinical management. METHODS The Acute Surgical Unit database at a high-volume general surgical referral centre was queried to identify cases of acute pancreatitis secondary to hypertriglyceridaemia between 2016 and 2019. Patient demographics, clinical manifestations, biochemical derangements and treatment regimens were analysed. Current related literature was reviewed. RESULTS There were 496 presentations for acute pancreatitis of which 14 presentations (2.8%), amongst 12 patients were due to hypertriglyceridaemia. The mean triglyceride level at presentation was 92.46 (standard deviation 46.9) mmol/L. Ten patients (83%) had poorly controlled type 2 diabetes. All patients were managed using conservative therapy combined with a restricted fat diet and commenced on long-term anti-lipid therapy to manage associated risk factors. In addition, 10 patients received an insulin infusion and one patient received insulin infusion, plasmapheresis and heparin infusion in combination. The median length of hospital stay was 5.5 (range 3-13) days. Two patients (16%) developed a recurrent episode related to non-compliance to medical therapy. CONCLUSION Hypertriglyceridaemia is a rare cause of acute pancreatitis. Successful management involves the treatment of acute pancreatitis in conjunction with long-term anti-lipid therapy and optimisation of associated risk factors.

Abstract
OBJECTIVE Acute perforated diverticulitis is frequently observed and spans a spectrum in the severity of its presentation. Emergency surgery is required in patients with generalized peritonitis; however, a large proportion of patients are clinically stable with localized peritonitis. This article aimed to examine this specific group of patients by reviewing the outcomes of their conservative management. METHODS A systematic literature search was performed on the MEDLINE and PubMed databases. The management outcomes of patients undergoing non-operative treatment for acute perforated diverticulitis were synthesized and tabulated. RESULTS Of 479 patients, 407 (85%) were successfully managed non-operatively. In total 70 (14.6%) patients failed non-operative treatment and underwent operative surgical management, and two (0.4%) died. Emergency surgery includes a Hartmann's operation (40%) and resection with anastomosis with or without stoma (24%), laparoscopic lavage (16%) and surgical drainage (20%). The success rate of conservative management was 94.0% and 71.4% for patients with pericolic and distant free air, respectively. Treatment failure was associated with a high volume of free air, distant free air and the presence of abscess. CONCLUSIONS Conservative management is safe and successful in patients with acute perforated diverticulitis without generalized peritonitis. The early recognition of patients who show clinical signs of persistent perforation is important to ensure the success of this strategy.
