Abstract
The nutritional status of hospitalised patients is often at risk or compromised and predisposed to further deterioration after discharge, leading to poor clinical outcomes, high healthcare costs, and poor quality of life. This paper aims to provide evidence-based best-practice recommendations to address this, supported by a national survey of healthcare professionals in Singapore and reviewed by a multidisciplinary expert panel under the Sarcopenia Interest Group of Society of Parenteral and Enteral Nutrition Singapore (SingSPEN). We advocate screening all patients with a validated tool which includes a disease activity/burden component, an easily accessible dietitian referral pathway for patients at risk of malnutrition, and an individualised nutrition care plan formulated and delivered using a multidisciplinary team approach for patients at risk or with malnutrition. A comprehensive team would include not only dietitians but also physicians, nurses, physiotherapists, speech therapists, and medical social workers working together towards a common goal. Information on why nutrition is important for good health and how it can be achieved should also be provided to all patients and their caregivers before and after hospital discharge. With the above recommendations, we seek to improve upon the current nutrition care processes at discharge for healthcare institutions in Singapore.

Abstract
A 62-year-old male was diagnosed to the Emergency Department with 5-cm posterior neck carbuncle, and was subsequently discovered to have severe necrotising fasciitis intraoperatively during saucerization of the carbuncle. Subsequently, the patient was admitted to the intensive care unit and underwent combined debridement by the General Surgery, Neurosurgery and Plastic Surgery team. The large defect necessitated a trapezius flap reconstruction for coverage. Three months post-surgery, the patient had recovered well with the full range of movement of his neck.

Abstract
BACKGROUND For patients undergoing abdominal surgery, multimodal prehabilitation, including nutrition and exercise interventions, aims to optimize their preoperative physical and physiological capacity. This meta-analysis aims to explore the impact of multimodal prehabilitation on surgical and functional outcomes of abdominal surgery. METHODS Medline, Embase and CENTRAL were searched for articles about multimodal prehabilitation in major abdominal surgery. Primary outcomes were postoperative complications with a Clavien-Dindo score ≥3, and functional outcomes, measured by the 6-Minute Walking Test (6MWT). Secondary outcome measures included the quality-of-life measures. Pooled risk ratio (RR) and 95% confidence interval (CI) were estimated, with DerSimonian and Laird random effects used to account for heterogeneity. RESULTS Twenty-five studies were included, analysing 4,210 patients across 13 trials and 12 observational studies. Patients undergoing prehabilitation had significantly fewer overall complications (RR = 0.879, 95% CI 0.781-0.989, p = 0.034). There were no significant differences in the rates of wound infection, anastomotic leak and duration of hospitalization. The 6MWT improved preoperatively in patients undergoing prehabilitation (SMD = 33.174, 95% CI 12.674-53.673, p = 0.005), but there were no significant differences in the 6MWT at 4 weeks (SMD = 30.342, 95% CI - 2.707-63.391, p = 0.066) and 8 weeks (SMD = 24.563, 95% CI - 6.77-55.900, p = 0.104) postoperatively. CONCLUSIONS As preoperative patient optimization shifts towards an interdisciplinary approach, evidence from this meta-analysis shows that multimodal prehabilitation improves the preoperative functional capacity and reduces postoperative complication rates, suggesting its potential in effectively optimizing the abdominal surgery patient. However, there is a large degree of heterogenicity between the prehabilitation interventions between included articles; hence results should be interpreted with caution.

Abstract
BACKGROUND Reconstruction with transverse colon-rectal anastomosis after an extended left hemicolectomy can be challenging. The Deloyers procedure, first described in 1964,1 comprises complete mobilization and rotation of the right colon, while maintaining the ileocolic artery, to achieve a well vascularized, tension-free colorectal anastomosis. We present a video of a laparoscopic Deloyers procedure with Indocyanin green (ICG) fluorescence as a useful adjunct. METHODS A middle-aged female underwent a laparoscopic anterior resection with anastomosis of mid-transverse to distal rectum with Deloyers procedure for synchronous splenic flexure adenocarcinoma and mid-rectal malignant polyp. Proximal transection was performed at mid-transverse colon while distal transection was performed at lower rectum. Tension-free mid-transverse colon-low rectal anastomosis was performed with Deloyers procedure. ICG fluorescence was performed for the colonic conduit, proximal, and distal transection margins to confirm perfusion just prior to anastomosis. Defunctioning loop ileostomy was then created 40 cm from the ileocecal valve. RESULTS Patient recovered uneventfully with functioning stoma on postoperative Day 1. Intraoperative use of ICG fluorescence has been proven to be an accurate tool assess anastomotic perfusion and has been associated with a lower anastomotic leak rate after colorectal resection.2 To our knowledge, this is the first report in which laparoscopic Deloyers procedure was performed under ICG guidance. Open Deloyers procedure with ICG was first reported by Okamoto et al.3 in April 2021 and remains the only other case report of Deloyers with ICG to date. CONCLUSIONS The Deloyers procedure can be safely performed laparoscopically and ICG fluorescence is a recommended adjunct to assess such unorthodox colorectal anastomosis.

Abstract
BACKGROUND AND AIMS Small bowel adenocarcinoma (SBA) is a rare neoplasm that is associated with Crohn's disease (CD). This study aims to quantify the prevalence of CD-SBA, review the current evidence of histopathology and molecular analysis findings, and identify the clinical presentation and outcomes of CD-SBA. METHODS Electronic databases Medline and Embase were searched for articles describing SBA in inflammatory bowel disease patients. The histopathology, molecular analysis findings, clinical presentation, prevalence, and outcomes of CD-SBA were extracted, and results were pooled with random effects. RESULTS In total, 33 articles were included in the analysis. Prevalence of SBA was 1.15 (CI: 0.31-2.33) per 1000 CD patients. Only 11% (CI: 0.04-0.21) of CD-SBA patients had observable radiological features. CD-SBA was most commonly found in the ileum (84%), diagnosed at stage 2 (36%), with main presenting complaints including obstruction, weight loss, and abdominal pain. Significant histopathological findings included adjacent epithelial dysplasia, and an equal distribution of well-differentiated (49%) and poorly differentiated subtypes (46%). Most prevalent genetic mutation was KRAS mutation (18%), followed by mismatch repair deficiency (9.7%). The 5-year overall survival for CD-SBA patients was 29% (CI: 0.18-0.41), and 33% (CI: 0.26-0.41) for de novo SBA. No statistically significant increase in risk for CD-SBA was noted for treatment with thiopurines, steroids, and 5-ASA. CONCLUSION Our meta-analysis found the prevalence of CD-SBA to be 1.15 per 1000 CD patients. The 5-year overall survival for CD-SBA was poor. The presenting symptoms were non-specific, and therefore the diagnosis requires a high index of suspicion.

Abstract
AIMS Upper gastrointestinal Crohn's disease (UGI-CD) is an important subclassification of Crohn's Disease (CD). We performed a systematic review and meta-analysis to evaluate the prevalence, risk factors, and clinical outcomes associated with UGI-CD. METHODS We searched Embase and Medline for articles reporting the clinical information of UGI-CD in CD patients, through 27 October 2020. Disease location and phenotype were coded according to the Montreal classification, and results were pooled with random effects by DerSimonian and Laird model. RESULTS 26 articles were included. The prevalence of UGI-CD was 13%. UGI-CD was most commonly found in the stomach (56%) and was associated with concurrent ileocolonic involvement (54%). Non-stricturing, non-penetrating UGI-CD was the most common behavioral phenotype (61%). L4-jejunal disease was associated with the highest rates of surgery. Region of origin did not significantly influence the location and phenotype of UGI-CD. Young, male patients presenting with erythema nodosum, aphthous ulcers and stricturing-phenotype are more likely to have UGI-CD, which in turn is linked to increased risk of hospitalization and surgery. CONCLUSION UGI-CD is present in 13% of patients with CD, and patients with L4-jejunal disease are more likely to require surgery. Further studies examining the effect of ethnicity and region on UGI-CD are needed.

Abstract
BACKGROUND AND AIMS The role of laparoscopic rectal cancer resection remains controversial. Thus, we aimed to conduct a one-stage meta-analysis with reconstructed patient-level data using randomized trial data to compare long-term oncologic efficacy of laparoscopic and open surgical resection for rectal cancer. METHODS Medline, EMBASE and Scopus were searched for articles comparing laparoscopic with open surgery for rectal cancer. Primary outcome was disease free survival (DFS) while secondary outcome was overall survival (OS). One-stage meta-analysis was conducted using patient-level survival data reconstructed from Kaplan-Meier curves with Web Plot Digitizer. Shared-frailty and stratified Cox models were fitted to compare survival endpoints. RESULTS Seven randomized trials involving 1767 laparoscopic and 1293 open resections for rectal cancer were included. There were no significant differences between both groups for DFS and OS with respective hazard ratio estimates of 0.91 (95% CI: 0.78-1.06, p = 0.241) and 0.86 (95% CI:0.73-1.02, p = 0.090). Sensitivity analysis for non-metastatic patients and patients with mid and lower rectal cancer showed no significant differences in OS and DFS between both surgical approaches. In the laparoscopic arm, improved DFS was noted for stage II (HR: 0.73, 95% CI:0.54-0.98, p = 0.036) and stage III rectal cancers (HR: 0.74, 95% CI:0.55-0.99, p = 0.041). CONCLUSIONS This meta-analysis concludes that laparoscopic rectal cancer resection does not compromise long-term oncologic outcomes compared with open surgery with potential survival benefits for a minimal access approach in patients with stage II and III rectal cancer.

Abstract
Bowel perforation as the first presentation of inflammatory bowel disease is rare and unusual in young patients. A previously asymptomatic 21-year-old Asian male presented with perforated small bowel secondary to previously undiagnosed Crohn’s disease. He underwent an exploratory laparotomy and subsequent small bowel resection and was commenced on mesalazine post-operation. He recovered well with subsequent regular follow-up with gastroenterology. The main management of Crohn’s disease is multidisciplinary in nature, and collaboration between different disciplines is inherent with the aim of reducing symptoms and maximizing patient quality of life.

Abstract
Purpose The COVID-19 pandemic has put tremendous strain on healthcare systems. Surgical societies worldwide have advised minimizing non-essential surgeries in order to preserve hospital resources. Given the medical resources and COVID-19 incidence between countries across the world differ, so should colorectal practices. No formal guidelines have emerged from Asia. We wanted to find out what the current practice was in Asian colorectal centres outside China. Introduction The COVID-19 pandemic has significantly impacted surgical practice worldwide. At the time of the writing of this paper, there are over 4.2 million cases reported with deaths exceeding 290 000 patients.1 With an abrupt disruption to worldwide supply chains, societal lockdowns and surge of cases into many hospitals, resource allocation was diverted and prioritised for all COVID-19 related services. Methods A questionnaire survey of current colorectal practice was carried out involving 3 major colorectal cancer centres, one each from 3 major cities: Singapore, Taichung and Daegu. Components of the survey include infrastructure and manpower, case selection, surgical approach, operating room management and endoscopy practice. Results All 3 centres continued to provide standard-of-care colorectal cancer surgery despite the COVID-19 pandemic. Two centres deferred surgery for benign colorectal conditions. Minimally Invasive Surgery (MIS) was still the preferred approach when indicated but with protocolized precautions undertaken. Other services such as pelvic exenteration, TATME and pelvic lymph node dissection were still offered if oncologically indicated. Elective diagnostic endoscopy services have also continued in two centres. Conclusion Elective colorectal services continue to take place in the 3 surveyed Asian hospitals with heightened precautions. Provided there is adequate resource, colorectal cancer services should still continue to prevent consequences of neglecting or delaying cancer treatment. Practice should hence be tailored to the local resource of individual centres accordingly.

Abstract
BACKGROUND Survival of patients with metastatic colorectal cancer (mCRC) varies. We aim to develop a prognostic score for mCRC after emergency surgery to guide treatment decisions. METHODS Newly diagnosed mCRC patients who presented with primary tumor-related complications and underwent emergency surgery between January 1999 and December 2013 were included. Univariate and multivariate Cox regression analyses were performed to identify covariates significantly associated with the time to death following surgery. A survival score was derived using the Cox regression equation. RESULTS The study cohort comprised 248 patients. Median patient age was 66 ± 13 years. Primary tumor was located in the left colon and rectum in 211 patients (85.1%) while 37 patients (14.9%) had primaries in the right colon. Liver, lung, and peritoneal metastases occurred in 161 patients (64.9%), 59 patients (23.8%), and 96 patients (38.7%), respectively. Majority of patients presented with either obstruction (174 patients, 70.1%) or perforation (52 patients, 21%). On multivariate analysis, age of 60 years or older (p = 0.007), carcinoembryonic antigen levels greater than 45 ng/ml (p = 0.022), presence of liver metastases (p = 0.024), and peritoneal carcinomatosis (p < 0.001) were found to be significantly associated with overall survival. A simplified score was derived with good survivors (score 0-2), moderate survivors (score 3-4), and poor survivors (score 5 and above) experiencing median survival of 7, 14, and 23 months, respectively (p < 0.001). CONCLUSION The management of mCRC presenting with an emergency is challenging. A prognostic score that estimates survival after emergency surgery may aid clinical decision-making.

Abstract
Abstract
Introduction
Post-operative recurrence after Crohn’s surgery poses a significant challenge to clinicians with an estimated of 70-90% recurrence rate. However, with the advent of biologics, reduction of recurrence after surgery has been observed in various landmark trials. Hence, we aim to quantify the rate of recurrence with post-operative biologics.
Method
Searches were done on Embase and Medline database for articles using biologics for post-operative management. A single arm meta-analysis with generalized linear mixed model and Clopper-Pearson method confidence interval was applied in the synthesis of the data on six months, one year, two year and five year.
Results
A total of 1,864 abstracts were identified, with a final total of 24 articles and 1042 patients were included in the meta-analysis. The one-year rate of recurrence for surgical, endoscopic and clinical was 3.08% (CI: 0.74% - 11.95%), 19.93% (15.81% - 24.81%) and 13.06% (CI: 8.18% - 18.92%) respectively. Correspondingly, the five-year recurrence 16.90% (CI: 9.57% - 28.11%), 84.21% (CI: 72.35% - 91.57%), 5.60% (CI: 9.92% -23.66%) respectively.
Conclusions
An observed reduction in surgical rates was reduced at five years with post-operative Crohn’s disease with biologics. Biologics therapy thus can be considered as a suitable alternative for reducing post-operative recurrence in individuals with higher risk.

Abstract
BACKGROUND The use of intra-operative colonic lavage (IOCL) with primary anastomosis remains controversial in the emergency left-sided large bowel pathologies, with alternatives including Hartmann’s procedure, manual decompression and subtotal colectomy.
AIM To compare the peri-operative outcomes of IOCL to other procedures.
METHODS Electronic databases were searched for articles employing IOCL from inception till July 13, 2020. Odds ratio and weighted mean differences (WMD) were estimated for dichotomous and continuous outcomes respectively. Single-arm meta-analysis was conducted using DerSimonian and Laird random effects.
RESULTS Of 28 studies were included in this meta-analysis, involving 1142 undergoing IOCL, and 634 other interventions. IOCL leads to comparable rates of wound infection when compared to Hartmann’s procedure, and anastomotic leak and wound infection when compared to manual decompression. There was a decreased length of hospital stay (WMD = -7.750; 95%CI: -13.504 to -1.996; P = 0.008) compared to manual decompression and an increased operating time. Single-arm meta-analysis found that overall mortality rates with IOCL was 4% (CI: 0.03-0.05). Rates of anastomotic leak and wound infection were 3% (CI: 0.02-0.04) and 12% (CI: 0.09-0.16) respectively.
CONCLUSION IOCL leads to similar rates of post-operative complications compared to other procedures. More extensive studies are needed to assess the outcomes of IOCL for emergency left-sided colonic surgeries.

Abstract
BACKGROUND Haemorrhoids result in a variety of symptoms that cause significant patient anxiety. Treatment has long been associated with post-operative complications, which cause significant symptoms and may result in readmissions. The open conventional haemorrhoidectomy (COH) is still regarded as the gold standard treatment for non-circumferential grade II-IV haemorrhoids. Laser haemorrhoidoplasty (LAH) has recently been studied and the initial results appear promising. This study aims to compare these 2 techniques in the treatment of symptomatic haemorrhoids. We hypothesize that LAH has significantly less pain and bleeding and better quality of life (QoL) scores 1, 3 and 12 months post-operatively. METHODS A prospective, randomized, double-blind, single-centre clinical trial will be conducted. All patients aged between 21 and 90 years who present with symptomatic grade II-IV haemorrhoids will be recruited. Exclusion criteria include those who have had previous operations for haemorrhoids and those with an increased risk of bleeding. Data collected will include patient demographics, pre- and intra-operative characteristics of the haemorrhoids, operative details and post-operative pain Visual Analogue Scale (VAS) score, complications, readmissions, and haemorrhoid-specific QoL surveys. Primary outcome will be median post-operative pain VAS score on post-operative days (POD) 1-10. Secondary outcomes include operative duration, bleeding on the first 10 days post-operatively, readmissions, procedure-related complications (fistulation, incontinence, stenosis), QoL scores, and recurrence of symptoms up to 12 months. DISCUSSION Results from this trial may demonstrate the superiority of LAH over COH in terms of post-operative pain and recovery. This would likely increase the adoption of LAH for the treatment of symptomatic haemorrhoids. TRIAL REGISTRATION This trial was registered on 1/4/2020 at ClinicalTrials.gov.

Abstract
Conventional colectomy, and the Japanese Society for Cancer of the Colon and Rectum (JSCCR) D2 Lymphadenectomy (LND2), are currently considered standard of care for surgical management of colon cancer. Colectomy with complete mesocolic excision (CME) and JSCCR D3 Lymphadenectomy (LND3) are more radical alternative approaches and provide a greater degree of lymph nodal clearance. However, controversy exists over the long-term benefits of CME/LND3 over non-CME colectomies (NCME)/LND2. In this study, we performed a systematic review and meta-analysis to compare the surgical, pathological, and oncological outcomes of CME/LND3 with NCME/LND2. Embase, Medline and CENTRAL databases were searched from inception until May 15, 2020, in accordance with PRISMA guidelines. Studies were included if they compared curative intent CME/LND3 with NCME/LND2. Weighted mean differences (WMD) and odds ratios (OR) were estimated for continuous and dichotomous outcomes respectively. Out of 1310 unique citations, 106 underwent full-text review, and 30 were included for analysis. In total, 21,695 patients underwent resection for colon cancer. 11,625 received CME/LND3, and 10,070 underwent NCME/LND2. No significant differences were found in post-operative morbidity and mortality. Both overall and disease-free survival favored CME/LND3 (5-year OS: OR = 1.29; 95% CI 1.02 to 1.64, p = 0.03; 5-year DFS: OR = 1.61; 95% CI 1.14 to 2.28; p = 0.007). This is the first systematic review and meta-analysis to demonstrate that CME/LND3 has superior long-term survival outcomes compared to NCME/LND2.

Abstract
The Kono-S anastomosis was introduced in 2011 as an alternative anastomosis in Crohn's disease (CD) surgery. Since then, prevailing evidence of the favorable results of the Kono-S anastomosis has been published from around the world. We conducted this study to analyze the effectiveness of the Kono-S anastomosis, by searching Medline, Embase, CNKI, and google scholar. Binominal data were analyzed after Freeman-Tukey double-arcsine transformation. Comparative data were analyzed using the Mantel-Haenszel model for dichotomous outcomes and the mean difference for continuous outcomes. We identified 676 patients who underwent surgery with a Kono-S anastomosis. Surgical recurrence was pooled at an average of 0% (CI: 0.00-0.01) and a reduced mean Rutgeerts score of 1.375 (CI: 0.727-2.023) after Kono-S anastomosis. Endoscopic recurrence after sensitivity analysis was 5% (CI: 0.00-0.15). Complications were rare, with a 3% incidence of ileus (CI: 0.01-0.05), a 4% incidence of small bowel obstruction (CI: 0.01-0.10), a 1% incidence of an anastomotic leak incidence (CI: 0.00-0.03), and a 10% incidence of postoperative infection (CI: 0.03-0.20). Evidence from this meta-analysis favors the Kono-S anastomosis for CD patients, especially for ileocolic anastomosis. Thus, clinicians should consider the applicability of Kono-S anastomosis in respective institutions.

Abstract
Background/Aims Sigmoidoscopy is performed in most medical centers to evaluate the distal colons of young adults presenting with hematochezia who are at risk of developing proximal lesions. Colonoscopies offer more complete evaluations but are associated with a higher incidence of complications and possible low yield.
Methods An analysis was conducted on colonoscopies performed in our center on patients 40 years of age or younger. The study population was sub-divided into 2 age groups for analysis: <30 years of age and 30–39 years of age.
Results We recruited 453 patients for the study. Patients were 115 and 338 individuals that were <30 and 30–39 years of age, respectively. Hemorrhoids was identified as the cause of bleeding in the majority of cases. The overall incidence of polyps was 6.5%; this was significantly higher in the 30–39 age group (7.4% vs. 1.7%, p=0.026). There were two cases of advanced/malignant polyps. While the majority of the polyps were in the distal colon, 28% of the polyps in the older age group were found in the proximal colon. There was one case of colonic perforation.
Conclusions Colonic polyps are more prevalent in patients aged 30–39. Colonoscopies should be considered for patients over the age of 30 with rectal bleeding.

Abstract
BACKGROUND An objective algorithm for the management of suspected appendicitis guided by the Alvarado Score had previously been proposed. This algorithm was expected to reduce computed tomography (CT) utilization without compromising the negative appendectomy rate. This study attempts to validate the proposed algorithm in a randomized control trial. METHODS A randomized control trial comparing the management of suspected acute appendicitis using the proposed algorithm compared to current best practice, with the rate of CT utilization as the primary outcome of interest. Secondary outcomes included the percentage of missed diagnosis, negative appendectomies, length of stay in days, and overall cost of stay in dollars. RESULTS One hundred sixty patients were randomized. Characteristics such as age, ethnic group, American Society of Anesthesiologist score, white cell count, and symptom duration were similar between the two groups. The overall CT utilization rate of the intervention arm and the usual care arm were similar (93.7% vs 92.5%, p = 0.999). There were no differences in terms of negative appendectomy rate, length of stay, and cost of stay between the intervention arm as compared to the usual care arm (p = 0.926, p = 0.705, and p = 0.886, respectively). Among patients evaluated with CT, 75% (112 out of 149) revealed diagnoses for the presenting symptoms. CONCLUSION The proposed AS-based management algorithm did not reduce the CT utilization rate. Outcomes such as missed diagnoses, negative appendectomy rates, length of stay, and cost of stay were also largely similar. CT utilization was prevalent as 93% of the study cohort was evaluated by CT scan. TRIAL REGISTRATION The study has been registered at ClinicalTrials.gov (NCT03324165, Registered October 27 2017).

Abstract
PURPOSE Microsatellite instability in colorectal cancer (CRC) and its long-term outcomes remains poorly studied in Asians. We investigate the prognostic significance of microsatellite instability in an Asian population and assess its clinical impact in patients who undergo adjuvant chemotherapy. METHODS Six hundred fifty-four consecutive CRC patients who underwent surgical resection between January 2010 and December 2012 were recruited. Survival was estimated using the Kaplan-Meier approach. Univariate Cox proportional hazard models were used to estimate the hazard ratios for variables associated with survival. A subgroup analyses was performed for stage III patients who underwent chemotherapy to evaluate the prognostic significance of microsatellite instability in this group. RESULTS Five hundred ninety-one (90.4%) patients were microsatellite stable (MSS) while 63 (9.6%) were microsatellite instable (MSI). Three years recurrence-free survival (RFS) and disease-specific survival (DSS) were 83.7 versus 73.7% (p = 0.295) and 87.1 versus 91.2% (p = 0.307) in MSS and MSI tumors, respectively. Among stage III patients who received adjuvant therapy, MSI status was found to be an adverse prognostic factor for RFS (HR 2.74 (95% CI 1.43-5.26), p = 0.002). This remained significant on multivariate analysis (HR 2.38 (95% CI 1.15-4.93), p = 0.018). Adjuvant chemotherapy was associated with survival benefit for patients with MSS tumors (HR 0.35, 95% CI 0.17-0.69, p = 0.002) but not MSI tumors (HR 0.67, 95% CI 0.08-8.15, p = 0.750). CONCLUSIONS MSI status is not a prognostic indicator in the general CRC population but appears to be an adverse prognostic indicator for RFS in stage III CRC patients who received adjuvant chemotherapy.

Abstract
Jejunal lipomata are an unusual cause of adult intussusception. We report a case of a 44-year-old Chinese woman who presented with a 3-day history of abdominal pain and nausea; she had a 5-year history of similar episodic symptoms after meals. Contrast-enhanced CT revealed a fat-density lead point in the jejunum resulting in intussusception. Single port laparoscopic surgery was performed with reduction of the intussusception, bowel resection and primary anastamosis. Histology confirmed a benign submucosal lipoma. We discuss the recent published literature on this rare entity and show CT images and intraoperative pictures.

Abstract
Gastrointestinal stromal tumour (GIST are the most common mesenchymal tumours; however, rectal GISTs account for <5%. In the pelvis they represent a diagnostic challenge with giant GISTs likely to be malignant. They may present with urological, gynaecological or rectal symptoms. Sphincter-preserving surgery can be aided by neoadjuvant therapy. We present an uncommon case of giant rectal GIST masquerading as acute urinary retention.

Abstract
INTRODUCTION Conventional practice of parathyroidectomy has been collar incision with bilateral neck exploration and a four-gland evaluation. Our local practice involves simplified parathyroidectomy via mini-incision without routine use of intraoperative adjuncts. The aim of this study is to demonstrate that a good success rate can be achieved, which will hopefully encourage more to undertake minimally invasive parathyroid surgery. MATERIALS AND METHODS A prospective case series of the first 100 patients undergoing minimally invasive parathyroidectomy (MIP) by a single surgeon at a single institution were included. Preoperatively, patients underwent ultrasonography (US) and/or a sestamibi (MIBI) scan for localisation. Parathyroidectomy was performed following an algorithm of intraoperative decisions. Serum calcium and/or parathyroid hormone levels were checked at follow-up. Postoperative normocalcaemia was considered success independent of serum parathyroid hormone levels RESULTS The patients had a median age of 63 years. Of the 100 patients, 83 were female and 17 male. Seven patients had a conversion to bilateral exploration. The mean operative time for unilateral and bilateral exploration was 42.38 minutes and 76.43 minutes respectively. Separately, a MIBI scan and US lateralised the side of the lesion in 82.8% and 79.5% of cases respectively. When US and the MIBI scan agreed, the predictive accuracy of the side of the lesion was 87.5%. The majority of patients (96%) had a successful return to normocalcaemia. No complications were encountered. CONCLUSIONS Excellent results are achievable with simplified MIP even without intraoperative adjuncts. Preoperative localisation is helpful in determining the side of incision. Our technique demonstrates a key principle of surgery: to keep things simple.

Abstract
OBJECTIVES The United Kingdom abdominal aortic aneurysm (AAA) screening programme refers aneurysms with ultrasound (US) diameters of ≥5.5 cm to vascular services for consideration of computed tomography (CT) and intervention. We investigated the discrepancy between US and CT, implications on clinical decisions and question at which stage CT be used. DESIGN/METHODS AAA USs over 5 years were retrospectively analysed. Patients included had aneurysms measuring ≥5 cm on US with subsequent CT within 2 months (n = 123). Based on maximum US diameters, 44 patients had aneurysms between 5 and 5.4 cm (group I) and 79 patients ≥5.5 cm (group II). Results were cross-referenced. Correlation and limits of agreement were calculated. Two radiologists re-measured 44 pairs of CT/US scans and the inter-observer bias in determining discrepancies between imaging modalities calculated. RESULTS Mean difference between imaging modalities was 0.21 cm (±0.39 cm, p < 0.001). Limits of agreement were -0.55 to 0.96 cm, exceeding clinical acceptability. Mean difference was higher and significant in group I (0.39 cm, p < 0.001) compared to group II (0.10 cm, p > 0.05). Seventy-percent of group I patients had CT scans revealing diameters of ≥5.5 cm. Inter-observer bias was not significant. CONCLUSION Significant differences between imaging modalities, more in US diameters of below 5.5 cm, exist. We recommend AAAs measuring ≥5 cm on US should undergo earlier referral to a vascular service and CT.

Abstract
An 80-year-old woman with a history of bilateral breast cancer was referred for investigation of hypercalcaemia, initially suspected to be bone metastasis. Sestamibi scan revealed the cause to be a large parathyroid adenoma which was then removed. Hypercalcaemia is the most frequent metabolic complication of breast cancer. Primary hyperparathyroidism is one of the most frequent causes of benign hypercalcaemia, but is often not considered in oncology patients. This case illustrates the importance of considering two primary pathologies.

Abstract
INTRODUCTION Antibiotics gained a place in the management of acute appendicitis when the bacterial aetiology was demonstrated. Culture swabs were obtained routinely during appendicectomies to guide antibiotic use. Although current antimicrobial therapy use has become prophylactic, empirical and broad spectrum, this age-old practice still remains. Our study questions the value of this traditional practice. MATERIALS AND METHODS All adult and paediatric patients undergoing emergency appendicectomy over three years were retrospectively reviewed. Microbiology and appendix histology reports were retrieved. Occurrence of infective post-operative morbidity was recorded via hospital notes. RESULTS A total of 652 appendectomies (age 1 month to 81 years, median 20 years) were performed in a 36 month period. Four hundred and thirty-five/six hundred and fifty-two (66.7%) had intra-operative swabs taken. One hundred and forty/four hundred and thirty-five (32%) revealed presence ofa pathogens. One hundred and twenty-two/four hundred and thirty-five (28%) were sensitive to broad spectrum empirical antibiotics and only 18/435 (4.1%) cultured resistant strains. Forty-two/six-hundred and fifty-two (6.4%) patients had postoperative infective complications. Twenty-nine/forty-two (68%) had a different organism responsible for this complication. The highest proportion of positive cultures and post-operative infective complications was observed in the extremes of ages (< 10 and > 50 years) and in gangrenous appendicitis. CONCLUSION A majority of intra-operative swabs were negative or isolated commensal flora. Pathogens causing postoperative morbidity were frequently different from those isolated intra-operatively. None of the patients had a change of management based on the swab results. Hence routine intra-peritoneal swabs remains of little clinical value.

Abstract
Bochdalek hernias on the right side of the diaphragm are very rarely diagnosed in adults. We review a case of a 35-year-old female who presented acutely with intestinal obstruction. Plain and cross-sectional imaging identified a large right-sided Bochdalek hernia, containing colon, causing a mechanical obstruction and, surprisingly, concurrent appendicitis. The patient underwent an emergency laparotomy. At surgery the colon was reduced and was viable. The diaphragmatic defect was repaired using non-absorbable sutures and an appendicectomy was then performed for purulent appendicitis. She made an uneventful recovery and remains well at 9-month follow-up. We discuss what we believe to be the first reported case of an obstructed right-sided Bochdalek's hernia associated with appendicitis in an adult and review the published literature on this rare condition.
