Abstract
BACKGROUND An increasing number of older patients are undergoing emergency laparotomy (EL). Frailty is thought to contribute to adverse outcomes in this group. The best method to assess frailty and impacts on long-term mortality and other important functional outcomes for older EL patients have not been fully explored. METHODS A prospective multicenter study of older EL patients was conducted across four hospital sites in New Zealand from August 2017 to September 2022. The Clinical Frailty Scale (CFS) was used to measure frailty-defined as a CFS of ≥5. Primary outcomes were 30-day and one-year mortality. Secondary outcomes were postoperative morbidity, admission for rehabilitation, and increased care level on discharge. A multivariate logistic regression analysis was conducted, adjusting for age, sex, and ethnicity. RESULTS A total of 629 participants were included. Frailty prevalence was 14.6%. Frail participants demonstrated higher 30-day and 1-year mortality-20.7% and 39.1%. Following adjustment, frailty was directly associated with a significantly increased risk of short- and long-term mortality (30-day aRR 2.6, 95% CI 1.5, 4.3, p = <0.001, 1-year aRR 2.0, 95% CI 1.5, 2.8, p < 0.001). Frailty was correlated with a 2-fold increased risk of admission for rehabilitation and propensity of being discharged to an increased level of care, complications, and readmission within 30 days. CONCLUSION Frailty was associated with increased risk of postoperative mortality up to 1-year and other functional outcomes for older patients undergoing EL. Identification of frailty in older EL patients aids in patient-centered decision-making, which may lead to improvement in outcomes.

Abstract
BACKGROUND Sarcopenia refers to the progressive age- or pathology-associated loss of skeletal muscle. When measured radiologically as reduced muscle mass, sarcopenia has been shown to independently predict morbidity and mortality after elective abdominal surgery. However, the European Working Group on Sarcopenia in Older People (EWGSOP) recently updated their sarcopenia definition, emphasizing both low muscle 'strength' and 'mass'. The aim of this systematic review and meta-analysis was to determine the prognostic impact of this updated consensus definition of sarcopenia after elective abdominal surgery. METHODS MEDLINE, Embase, Scopus, and Cochrane Central Register of Controlled Trials (CENTRAL) databases were systematically searched for studies comparing prognostic outcomes between sarcopenic versus non-sarcopenic adults after elective abdominal surgery from inception to 15 June 2022. The primary outcomes were postoperative morbidity and mortality. Sensitivity analyses adjusting for confounding patient factors were also performed. Methodological quality assessment of studies was performed independently by two authors using the QUality in Prognosis Studies (QUIPS) tool. RESULTS Twenty articles with 5421 patients (1059 sarcopenic and 4362 non-sarcopenic) were included. Sarcopenic patients were at significantly greater risk of incurring postoperative complications, despite adjusted multivariate analysis (adjusted OR 1.56, 95 per cent c.i. 1.39 to 1.76). Sarcopenic patients also had significantly higher rates of in-hospital (OR 7.62, 95 per cent c.i. 2.86 to 20.34), 30-day (OR 3.84, 95 per cent c.i. 1.27 to 11.64), and 90-day (OR 3.73, 95 per cent c.i. 1.19 to 11.70) mortality. Sarcopenia was an independent risk factor for poorer overall survival in multivariate Cox regression analysis (adjusted HR 1.28, 95 per cent c.i. 1.13 to 1.44). CONCLUSION Consensus-defined sarcopenia provides important prognostic information after elective abdominal surgery and can be appropriately measured in the preoperative setting. Development of targeted exercise-based interventions that minimize sarcopenia may improve outcomes for patients who are undergoing elective abdominal surgery.

Abstract
Revisional surgery may be required in a subset of patients who remain symptomatic despite undergoing laparoscopic fundoplication (LF) for gastroesophageal reflux disease (GERD). While revisional LF (RLF) is feasible in these patients, laparoscopic Roux-en-Y gastric bypass (LRYGB) may serve as an alternative, although its efficacy and safety remains unknown. This study aimed to determine the outcomes of LRYGB in symptomatic patients following failed LF for GERD. MEDLINE, EMBASE, and PubMed databases were systematically searched for studies reporting LRYGB outcomes in symptomatic adults despite undergoing LF for GERD. Postoperative symptom resolution, recurrence of heartburn and dysphagia, proton pump inhibitor (PPI) use, and body mass index (BMI) reduction were assessed to determine LRYGB efficacy. Postoperative morbidity and mortality were used to evaluate LRYGB safety. Twenty-two studies with 1523 patients were included. Pooled rates of symptom resolution, recurrence of heartburn and dysphagia, PPI use, morbidity, and mortality were 71.6% (95% CI 59.4-86.4), 15.6% (8.9-27.3), 20.7% (12.5-34.3), 29.6% (18.8-46.5), 39.5% (29.9-52.3), and 2.2% (1.2-4.0), respectively, following LRYGB. Similar rates were observed after RLF. However, BMI reduction was significantly greater after LRYGB compared with RLF (mean difference 6.1 kg/m2, 4.8-7.4; p < 0.0001). LRYGB resulted in symptom relief in a majority of patients, and proved comparable to RLF regarding symptom recurrence and PPI use. Morbidity and mortality following LRYGB also did not differ from RLF. However, LRYGB was associated with considerably greater weight loss relative to RLF. Therefore, LRYGB is efficacious and an acceptable revisional procedure in symptomatic GERD patients who have previously undergone LF.

Abstract
BACKGROUND Cholecystectomy is one of the most commonly performed abdominal operations. Rising demands on acute operating theater availability and resource utilization in the daytime have led to acute cholecystectomy being performed out-of-hours (in the evenings, at night, or on weekends), although it remains unknown whether outcomes differ between out-of-hours and in-hours (during the daytime on weekdays) acute cholecystectomy. This systematic review and meta-analysis aimed to compare outcomes following out-of-hours versus in-hours acute cholecystectomy. METHODS The study protocol was prospectively registered on PROSPERO (ID: CRD42021226127). MEDLINE, EMBASE, and Scopus databases were systematically searched for studies comparing outcomes following out-of-hours and in-hours acute cholecystectomy in adults with any acute benign gallbladder disease. The outcomes of interest were rates of bile leakage, bile duct injury, overall postoperative complications, conversion to open cholecystectomy, specific intraoperative and postoperative complications, length of stay, readmission, and mortality. Subgroup (evening/night-time vs. daytime, weekend vs. weekday, acute surgical unit [ASU]-only, non-ASU, and laparoscopic-only) and sensitivity analyses of adjusted multivariate regression analysis results was also performed. RESULTS Eleven studies were included. There were no differences between out-of-hours and in-hours acute cholecystectomy for rates of bile leakage, bile duct injury, overall postoperative complications, conversion to open cholecystectomy, operative duration, readmission, mortality, and postoperative length of stay. Higher rates of postoperative sepsis (odds ratio, 1.58; 95% confidence interval, 1.04-2.41; p = 0.03) and pneumonia (odds ratio, 1.55; 95% confidence interval, 1.06-2.26; p = 0.02) were observed following out-of-hours acute cholecystectomy on univariate meta-analysis, but not after the adjusted multivariate meta-analysis. Higher conversion rates were observed when out-of-hours cholecystectomy was performed in centers without an ASU. CONCLUSION This systematic review and meta-analysis has not shown an increased risk in overall or specific complications associated with out-of-hours compared with in-hours acute cholecystectomy. However, future studies should assess the potential impact of structural hospital factors, such as an ASU, on outcomes following out-of-hours acute cholecystectomy. LEVEL OF EVIDENCE Systematic Review and Meta-Analysis Study, Level IV.

Abstract
AIM Haemorrhoids are frequently encountered by the general or colorectal surgeon. Although a benign disease, those with symptomatic, advanced grades frequently require excisional haemorrhoidectomy for definitive management. Despite their widespread nature, the epidemiological burden of haemorrhoids and haemorrhoidectomies on populations is not well described. This study seeks to establish the incidence of both haemorrhoids diagnosed and haemorrhoidectomies performed in New Zealand. METHOD This is a population-based cross-sectional study examining the incidence of all patients who were newly diagnosed with haemorrhoids in New Zealand public hospital outpatient clinics and those who received excisional haemorrhoidectomy in New Zealand public hospitals from 2007 to 2016. Data were extracted and linked using the New Zealand National Minimum Dataset and the National Non-Admitted Patient Collection. Variables collected included age group, sex, ethnicity and geographical location. RESULTS A total of 46 095 recorded diagnoses of haemorrhoids were made, with a total of 18 739 haemorrhoidectomies in the 10-year period recorded. The incidence rate of diagnosis increased from 84.6 to 120.5 per 100 000 and the incidence rate of haemorrhoidectomies performed from 30.4 to 51.1 per 100 000, a significantly increased annual incidence. There was a unimodal peak prevalence in the fifth decade of life with women more affected. Europeans formed the largest group affected, with Asians showing the highest rate of increased incidence. CONCLUSION There is an increasing incidence of patients with symptomatic haemorrhoids presenting to the New Zealand public healthcare system, with a preponderance in working age adults, especially women.

Abstract
BACKGROUND Emergency laparotomy (EL) is a common procedure with high mortality leading to several efforts to record and reduce mortality. Risk scores currently used by quality improvement programmes either require intraoperative data or are not specific to EL. To be of utility to clinicians/patients, estimation of preoperative risk of mortality is important. We aimed to explore individual preoperative risk factors that might be of use in developing a preoperative mortality risk score. METHODS Two independent reviewers identified relevant articles from searches of MEDLINE, EMBASE and Cochrane databases from January 1980 to January 2018. We selected studies that evaluated only preoperative predictive factors for mortality in EL patients. RESULTS The search yielded 6648 articles screened, with 22 studies included examining 157 728 patients. The combined post-operative 30-day mortality was 13%. All, but one small study, were at low risk of bias. A meta-analysis of results was not possible due to the heterogeneity of populations and outcomes. Age, American Society of Anesthesiologists, preoperative sepsis, dependency status, current cancer and comorbidities were associated with increased mortality. Acute physiological derangements seen in renal, albumin and complete blood count assays were strongly associated with mortality. Delay to surgery and diabetes did not influence mortality. Higher body mass index was protective. CONCLUSION Preoperatively, risk factors identified can be used to develop and update risk scores specific for EL mortality. This scoping review focused on the preoperative setting which helps tailor treatment decisions. It highlights the need for further research to test the relevance of newer risk factors such as frailty and nutrition.

Abstract
BACKGROUND Excisional haemorrhoidectomy has been traditionally performed under general or regional anaesthesia. However, these modes are associated with complications such as nausea, urinary retention and motor blockade. Local anaesthesia (LA) alone has been proposed to reduce side effects as well as to expedite ambulatory surgery. This systematic review aims to assess LA versus regional or general anaesthesia for excisional haemorrhoidectomy. METHODS A systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. MEDLINE, EMBASE and CENTRAL databases were searched to 13 January 2020. All randomised controlled trials comparing LA only versus regional or general anaesthesia in patients who received excisional haemorrhoidectomy were included. The main outcomes included pain, adverse effects and length of stay. RESULTS Nine trials, consisting of six studies comparing local versus regional anaesthesia and three comparing LA versus general anaesthesia, were included. Meta-analysis showed a significantly lower relative risk for need of rescue analgesia (RR 0.32 [95% CI 0.16-0.62]), intra-operative hypotension (RR 0.17 [95% CI 0.04-0.76]), headache (RR 0.13 [0.02-0.67]) and urinary retention (RR 0.17 [95% CI 0.09-0.29]) for LA when compared with regional anaesthesia. There was mixed evidence for both regional and general anaesthesia in regard to post-operative pain. CONCLUSIONS LA alone may be considered as an alternative to regional anaesthesia for excisional haemorrhoidectomy with reduced complications and reduction in the amount of post-operative analgesia required. The evidence for LA compared to general anaesthesia for haemorrhoidectomy is low grade and mixed.

Abstract
BACKGROUND High concentrations of local anaesthetic have an anti-proliferative effect on colonic cancer in vitro. Intraperitoneal local anaesthetic (IPLA) has shown analgesic benefit and improved recovery in the perioperative setting. The long-term effects of IPLA in colon cancer resection have not been examined. This study aims to review the survival and oncological outcomes of a previously conducted trial that compared perioperative IPLA with placebo. METHODS Sixty patients underwent colonic resection for benign and malignant disease as part of a double-blinded, randomized, placebo-controlled study between September 2008 and November 2009. The IPLA group received instillation of intraperitoneal ropivacaine before dissection followed by a 3-day infusion. The placebo group was treated identically but with 0.9% saline solution. A follow-up analysis was conducted to evaluate overall survival, disease-free survival and recurrence specifically for patients undergoing resection for stages I-III colon cancer. Kaplan-Meier analysis was performed, and the log-rank test was used to evaluate difference in survival between groups. RESULTS Thirty-seven of the 60 patients had stages I-III colon cancer and were included in this analysis. Nineteen patients were in the placebo group. There was no significant difference in overall survival or all-cause mortality. There was a higher incidence of cancer-specific mortality in the local anaesthetic group (P < 0.046). CONCLUSION It does not appear that IPLA is associated with a significant survival benefit in patients with colonic malignancy undergoing colectomy. Other studies are needed to analyse the long-term outcomes.

Abstract
AIM Excisional haemorrhoidectomy is the gold standard for management of advanced symptomatic haemorrhoids. Although an effective treatment, it is associated with significant postoperative morbidity with pain, bleeding and a high readmission rate. This study seeks to investigate potential risk factors that may predict unplanned 30-day readmissions following excisional haemorrhoidectomy. METHOD A retrospective cohort review of all haemorrhoidectomies performed at Counties Manukau District Health Board, Auckland, New Zealand, between January 2012 and December 2017 was performed. Baseline demographic data, readmission data and potential variables for readmission were recorded. Univariate and multivariate logistic regression analyses were performed to determine significant variables for readmission within 30 days. RESULTS In total, 485 cases of excisional haemorrhoidectomy were included in the final analysis with 62 (12.8%) unplanned readmissions. The demographics between the no readmission and unplanned readmission groups were similar. Multivariate logistic regression analysis demonstrated that male gender (P = 0.018) and the use of non-diathermy devices (P = 0.017) were significant risk factors for readmission. Initial dispensing of opioid analgesia did not decrease the risk of readmission. CONCLUSION This study suggests that male gender and surgical technique are associated with increased risk of readmission.

Abstract
BACKGROUND Multimodal analgesic regimes are required to treat pain. Intraperitoneal (IP) agents, such as local anesthetics (LAs), have been shown to reduce pain after abdominal surgery. Other IP analgesics have been tested in several randomized control trials (RCTs), but no reviews or guidelines have evaluated their use. Tramadol is an effective oral and intravenous analgesia with recent evidence supporting the use of IP tramadol (IPT). We aimed to review the efficacy of IPT as an adjunct to intraperitoneal local anesthetics (IPLAs) for pain relief after abdominal surgery. MATERIALS AND METHODS Relevant articles were identified by two independent reviewers from MEDLINE, EMBASE and PubMed using Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines up to January 2019. Only RCT comparing IPT + IPLA with IPLA alone were included. Outcomes recorded were the postoperative analgesic requirement, pain scores at 4 h and 24 h and adverse events. Data were analyzed with Review Manager, version 5.3. RESULTS A total of five RCTs (4× laparoscopic cholecystectomy and 1× abdominal hysterectomy) were included in this review from 419 studies screened. All doses were given as a single bolus. Pain relief requirements over the first 24 h weres less in the IPT + IPLA groups when compared with those in IPLA alone. Pain scores were less for IPT + IPLA groups at 4 h and 24 h. There were no significant differences in adverse events between groups. CONCLUSIONS In summary, IPT, in combination with IPLA, is effective in the management of acute postoperative pain and reduces the total amount of pain relief consumed in the first 24 h after surgery. Studies reporting the use of IPT + IPLA reported no toxicity or systemic adverse events. Further research into standardizing the dosing of IPT to optimize its effectiveness and further reduce the additional analgesic requirement is indicated.

Abstract
INTRODUCTION Sarcopenia is the progressive loss of skeletal muscle mass, strength and general decline in function associated with age, and has previously been shown to be a predictor of poor outcomes following surgery. Computed tomography (CT)-assessed sarcopenia has been proposed to be an independent predictor of outcomes for trauma patients. This systematic review aims to determine the impact of CT-assessed sarcopenia on patient mortality following trauma. MATERIALS AND METHODS A systematic review and meta-analysis of the literature was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. EMBASE, MEDLINE and CENTRAL databases were searched from database inception to 26 November 2018. Bibliographies of included articles were hand searched for potential articles. All observational studies which included trauma patients who had skeletal muscle mass or density assessed by CT were included in the review. Two authors independently performed the search with decisions reached by consensus. Meta-analysis was performed using Review Manager v5.3 using a random effects model. The primary outcome was all cause mortality, as established a priori. RESULTS Following an initial search of 1984 records, a total of 20 retrospective observational studies were included for qualitative analysis. Ten of these studies consisting of a pooled, partly-overlapping, 2867 patients were included in the meta-analysis. There was a wide variation in the reported prevalence of sarcopenia (25.0-71.1%). Sarcopenia patients were at a significantly increased risk of mortality during inpatient stay (RR 1.96 [95%CI 1.30-2.94], p = 0.001), at 30 days (RR 1.60 [95%CI 1.21-2.13], p = 0.001) and at 1-year (RR 3.11 [95%CI 1.94-4.96], p < 0.00001). There was no significant difference in total complications encountered, ICU duration or total inpatient stay. CONCLUSION Sarcopenia identified by CT is associated with increased risk of inpatient, 30-day, and 1-year mortality in trauma patients.

Abstract
BACKGROUND Post-operative pain is a major issue following excisional haemorrhoidectomy. Although metronidazole by both oral and topical administration routes has been shown to reduce pain after haemorrhoidectomy, its use remains a contentious issue. This systematic review and meta-analysis aims to investigate the effect of metronidazole on post-operative pain after excisional haemorrhoidectomy. METHODS A systematic review of the literature was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs) published in PubMed/MEDLINE, EMBASE, CENTRAL and CINAHL, from inception to December 2016 were retrieved. The primary outcome investigated was post-operative pain reported as visual analogue score (VAS). Secondary outcomes were analgesia use, complications and time to return to normal activity. Meta-analysis was performed using Review Manager version 5.3 software. RESULTS Nine randomized controlled trials including 523 patients were included in the final analysis. Five studies used oral administration and four used topical. Meta-analysis showed that post-operative VAS of patients receiving metronidazole by either route was significantly less than those in comparison groups. VAS means decreased at all the time points for both oral and topical metronidazole. Topical and oral routes of administration were not compared in any study. There was no increase in complication rates and return to normal activity was significantly earlier for patients receiving metronidazole (-4.49 days; 95% confidence interval [-7.70, -1.28]; P = 0.006). CONCLUSIONS Both topical and oral metronidazole reduce post-operative pain without an increase in complication rates and result in an earlier return to normal activity. Further work is required to determine which the optimum route of administration is.

Abstract
BACKGROUND Diverticulitis is a common condition with a broad spectrum of disease severity. A scoring system has been proposed for diagnosing diverticulitis, and a number of scoring systems exist for predicting prognosis associated with severe complications of diverticulitis such as peritonitis. However, predicting disease severity has not received as much attention. Therefore, the aim of this review was to identify the factors that are predictive of severe acute diverticulitis. METHODS A systematic literature search was performed using Medline, PubMed, EMBASE, and the Cochrane Library to identify papers that evaluated factors predictive of severe diverticulitis. Severe diverticulitis was defined as complicated diverticulitis (associated with haemorrhage, abscess, phlegmon, perforation, purulent/faecal peritonitis, stricture, fistula, or small-bowel obstruction) or diverticulitis that resulted in prolonged hospital admission, surgical intervention or death. RESULTS Twenty one articles were included. Studies were categorised into those that identified patient characteristics (n = 12), medications (n = 5), biochemical markers (n = 8) or imaging (n = 3) as predictors. Predictors for severe diverticulitis included first episode of diverticulitis, co-morbidities (Charlson score ≥ 3), non-steroidal anti-inflammatory drug use, steroid use, a high CRP on admission and severe disease on radiological imaging. Age and gender were not associated with disease severity. CONCLUSION A number of predictors exist for identifying severe diverticulitis, and CT remains the gold standard for diagnosing complicated disease. Patients who present with identified risk factors for severe disease warrant early imaging, closer in-patient observation and a lower threshold for early surgical intervention. Patients without these factors may be suitable for outpatient-based treatment.
