RESUMO
Robot-assisted general surgery, an advanced technology in minimally invasive procedures, is increasingly employed in elective general surgery, showing benefits over laparoscopy in specific cases. Although laparoscopy remains a standard approach for common acute abdominal conditions, the role of robotic surgery in emergency general surgery remains uncertain. This systematic review aims to compare outcomes in acute general surgery settings for robotic versus laparoscopic surgeries. A PRISMA-compliant systematic search across MEDLINE, EMBASE, Science Citation Index Expanded, and the Cochrane Library was conducted. The literature review focused on articles comparing perioperative outcomes of emergency general surgery managed laparoscopically versus robot-assisted. A descriptive analysis was performed, and outcome measures were recorded. Six articles, involving 1,063 patients, compared outcomes of robotic and laparoscopic procedures. Two articles covered cholecystectomies, while the others addressed ileocaecal resection, subtotal colectomy, hiatal hernia and repair of perforated gastrojejunal ulcers. The level of evidence was low. Laparoscopic bowel resection in patients with inflammatory bowel disease (IBD) had higher complications; no significant differences were found in complications for other operations. Operative time showed no differences for cholecystectomies, but robotic approaches took longer for other procedures. Robotic cases had shorter hospital length of stay, although the associated costs were significantly higher. Perioperative outcomes for emergency robotic surgery in selected general surgery conditions are comparable to laparoscopic surgery. However, recommending robotic surgery in the acute setting necessitates a well-powered large population study for stronger evidence.

INTRODUCTION: Sleeve gastrectomy (SG) is currently the most frequently performed procedure for obesity worldwide. Staple line reinforcement (SLR) has been suggested as a strategy to reduce the risk of staple line leak or bleeding; however, its use for SG in the United Kingdom (UK) is unknown. This study examined the effect of SLR on the development of postoperative complications from SG using a large national dataset from the UK. METHODS: Patients undergoing either primary or revision SG over 10 years from Jan 2012 to Dec 2021 were identified by the National Bariatric Surgery Registry. Comparative and logistic regression analyses were undertaken to determine the effect of SLR on staple line leak and bleeding. RESULTS: During this time, 14,231 patients underwent SG for whom there were complete data. Of these, 76.5% were female and the median age was 46 years (IQR: 36-53). The rate of surgical complications was 2.3% (n = 219/14,231). The incidence of bleeding was 1.3% (n = 179/14,231) and leak was 1.0% (n = 140/14,231). Over time, the use of SLR of any variety declined significantly from 99.7% in 2012 to 57.3% in 2021 (p < 0.001). Multivariable (adjusted) regression analysis demonstrated that neither the use of nor the type of reinforcement had any effect on the rate of bleeding or leaking. CONCLUSION: SLR for SG has declined in the UK since 2012. There were no differences in staple line leak or bleed with or without reinforcement.

BACKGROUND: No robust data are available on the safety of primary bariatric and metabolic surgery (BMS) alone compared to primary BMS combined with other procedures. OBJECTIVES: The objective of this study is to collect a 30-day mortality and morbidity of primary BMS combined with cholecystectomy, ventral hernia repair, or hiatal hernia repair. SETTING: This is as an international, multicenter, prospective, and observational audit of patients undergoing primary BMS combined with one or more additional procedures. METHODS: The audit took place from January 1 to June 30, 2022. A descriptive analysis was conducted. A propensity score matching analysis compared the BLEND study patients with those from the GENEVA cohort to obtain objective evaluation between combined procedures and primary BMS alone. RESULTS: A total of 75 centers submitted data on 1036 patients. Sleeve gastrectomy was the most commonly primary BMS (N = 653, 63%), and hiatal hernia repair was the most commonly concomitant procedure (N = 447, 43.1%). RYGB accounted for the highest percentage (20.6%) of a 30-day morbidity, followed by SG (10.5%). More than one combined procedures had the highest morbidities among all combinations (17.1%). Out of overall 134 complications, 129 (96.2%) were Clavien-Dindo I-III, and 4 were CD V. Patients who underwent a primary bariatric surgery combined with another procedure had a pronounced increase in a 30-day complication rate compared with patients who underwent only BMS (12.7% vs. 7.1%). CONCLUSION: Combining BMS with another procedure increases the risk of complications, but most are minor and require no further treatment. Combined procedures with primary BMS is a viable option to consider in selected patients following multi-disciplinary discussion.
RESUMO
Laparoscopic Roux-en-Y gastric bypass (RYGB) is crucial for significant weight reduction and treating obesity-related issues. However, the impact of gastrojejunostomy (GJ) anastomosis diameter on weight loss remains unclear. We investigate this influence on post-RYGB weight loss outcomes. A systematic search was conducted. Six studies met the inclusion criteria, showing varied GJ diameters and follow-up durations (1-5 years). Smaller GJ diameters generally correlated with greater short-to-medium-term weight loss, with a threshold beyond which complications like stenosis increased. Studies had moderate-to-low bias risk, emphasizing the need for precise GJ area quantification post-operation. This review highlights a negative association between smaller GJ diameters and post-RYGB weight loss, advocating for standardized measurement techniques. Future research should explore intra-operative and AI-driven methods for optimizing GJ diameter determination.

BACKGROUND: Emergency general surgery (EGS) is a major part of the provision of healthcare, and patients undergoing EGS are at elevated risk of morbidity and mortality. This study aimed to determine factors contributing to patients losing their independence and being discharged to residential and nursing homes having previously lived in their own residences. METHODS: Our local data uploaded to the National Emergency Laparotomy Audit (NELA) (2014-2022) were analyzed. This national database encompasses all major EGS cases undertaken in the United Kingdom. The variables considered were patient demographics, American Society of Anesthesiologists score, admission and discharge dates, presenting pathology, operation type, and discharge destination. Comparative analyses segmented patients based on postdischarge EGS destinations. Multivariable logistic regression identified factors linked to residential/nursing home placement after discharge. Significance was set at P < .05. RESULTS: Data from all patients in the NELA database (n = 1611) were analyzed. Approximately 1 in 10 patients older than 70 years never returned home. Patients requiring additional support were on average 8.6 years older (P = .008). At older than 80 years, the need for extra social support increased substantially with each increasing year in age, and those older than 85 years were more than twice as likely to require extra support than 80-year-olds (P < .001). Patients who died were 11.4 years older than those discharged without additional support (P < .001). CONCLUSION: A significant proportion of patients, particularly the elderly, do not return to their usual place of residence and require a higher level of care postemergency surgery. These important social factors need to be considered before operating given that they may have significant quality of life and economic implications.

BACKGROUND: Metabolic bariatric surgery tourism continues to rise and has become a growing concern for bariatric surgeons globally. With varying degrees of regulation, counselling and success, those that develop complications may have to deal with a multitude of challenges often distant from their country of operation. The aim of this study was to characterize the barriers and facilitators influencing individuals to undergo metabolic bariatric surgery tourism, in order to better understand the implications to the National Health Service and other healthcare systems. METHODS: A systematic literature search, restricted to the English language, was performed to identify relevant studies. All studies were included until December 2022, the last search date. Study quality was assessed with the validated mixed-methods appraisal tool. A Braun and Clarke thematic analysis was undertaken to identify themes and subthemes. RESULTS: A total of five studies met the inclusion criteria. Identified themes included: availability, accessibility, cost, eligibility, reputation, and stigma; the available evidence was of varying quality. CONCLUSION: This work identifies a series of subthemes influencing the decision to undertake metabolic bariatric surgery tourism. The results highlight the limited literature available in understanding the complex motivational insights; the scale of the problem in the current healthcare system; cost and long-term outcomes. A National Emergency Bariatric Surgery audit would allow generation of more robust data to explore further the issues of clinical relationships and networks and to guide policy making.

Robotic liver resections (RLR) are increasingly being performed and has previously been considered more costly. The aim is to explore the cost of RLR compared with laparoscopic and open liver resection in a single National Health Service (NHS) hospital. A retrospective review of patients who underwent RLR, LLR, and OLR from April 2014 to December 2022 was conducted. The primary outcomes were the cost of consumables and median income, and the secondary outcomes were the overall length of stay and mortality at 90 days. Overall, 332 patients underwent liver resections. There were 204 males (61.4%) and 128 females (38.6%), with a median age of 62 years (IQR: 51-77 years). Of these, 60 patients (18.1%) underwent RLR, 21 patients (6.3%) underwent LLR, and 251 patients (75.6%) underwent OLR. Median consumables cost per case was £3863 (IQR: £3458-£5061) for RLR, £4326 (IQR: £4273-£4473) for LLR, and £4,084 (IQR: £3799-£5549) for the OLR cohort (p = 0.140). Median income per case was £7999 (IQR: £4509-£10,777) for RLR, £7497 (IQR: £2407-£14,576) for LLR, and £7493 (IQR: £2542-£14,121) for OLR. The median length of stay (LOS) for RLR was 3 days (IQR: 2-4.7 days) compared to 5 days for LLR (IQR: 4.5-7 days) and 6 days for OLR (IQR: 5-8 days, p < 0.001). Within the NHS, RLR has consumable costs comparable to OLR and LLR. It is also linked with a shorter LOS and generates similar income for patients undergoing OLR and LLR.

The aim of this meta-analysis was to compare the effects of LRYGB and LSG on dyslipidemia. Studies comparing the effects of LRYGB and LSG on dyslipidemia with follow-up of 12 months or more were included. Twenty-four studies comprising seven RCTs and 17 comparative observational studies were included. Meta-analysis of RCTs (n=487) showed that improvement/resolution of dyslipidemia was better after LRYGB (68.5%, n=161/235) compared to LSG (48.4%, n=122/252). Patients undergoing LRYGB were more than twice as likely to experience improvement/resolution in dyslipidemia compared to those undergoing LSG (OR 2.28, 95% CI 1.21-4.29, p=0.010). Both LRGYB and LSG appears effective in improving dyslipidemia at >12 months after surgery; however, this improvement is more than twice higher after LRYGB compared to LSG.

Obesity has reached pandemic levels globally. Surgical management of obesity aims to establish metabolic control, weight loss and resolution of multiple health conditions and to improve quality of life. Here, we examine the role of surgery in the management of obesity within the context of a multidisciplinary team involving a variety of healthcare professionals. We highlight the importance of patient selection, perioperative care, the various types of bariatric surgery currently available as well as emerging procedures. In addition to clarifying the different types of procedure, we also examine the potential complications and issues of weight regain and failure to lose weight. Ultimately, bariatric surgery remains comparatively safe and with generally excellent results in terms of control of existing obesity-related conditions; with the ever-increasing number of patients living with obesity, the scope of bariatric surgery is thus likely to increase.

Background: Haemorrhoids are a very common disease and many professional societies have produced guidelines for their treatment. The aim of this study is to appraise the quality of the existing guidelines in the management of haemorrhoids. Methods: A systematic search of the literature was conducted in the EMBASE, Google Scholar, Cochrane library, and PubMed databases. The quality of guidelines was independently appraised using the Appraisal of Guidelines Research and Evaluation II (AGREE II) instrument by five of the authors. Results: Six guidelines of varying quality were identified and included in this study. The highest scoring guidelines were the SICCR (Società Italiana di Chirurgia Colorectale, which is Italian Society of Colorectal Surgery), ESCP (European Society of Coloproctology) and ASCRS (American Society of Colon and Rectal Surgeons) guidelines, scoring 86% each overall. There was considerable variability across not just the studies but across the different domains. The highest scoring domains were domain VI: editorial independence (median =95% across all studies) and domain I: Scope & Purpose (85%). The lowest scores were observed in domain V: Applicability (48%) and domain II: Stakeholder Involvement (41%). Only three of the six gained unanimous support for their use, whilst two of the guidelines were unanimously declared not suitable for clinical use. Conclusions: With the notable exception of three guidelines (SICCR, ESCP and ASCRS), the general quality of haemorrhoid guidelines is poor. Stakeholder (especially patient) involvement and instructions on how to implement recommendations is lacking from the majority of guidelines. This is an area that requires urgent attention if we are to improve guidelines in haemorrhoid management.
RESUMO
Baseline demographic characteristics and operations undertaken for patients having bariatric surgery in the United Kingdom are largely unknown. This study aimed to describe the profile of patients having primary bariatric surgery in the National Health Service (NHS) or by self-pay, and associated operations performed for both pathways. The National Bariatric Surgery Registry dataset for 5 years between January 2015 and December 2019 was used. 34 580 patients underwent primary bariatric surgery, of which 75.9% were NHS patients. Mean patient age and initial body mass index were significantly higher for NHS compared to self-pay patients (mean age 45.8 ± 11.3 [SD] vs. 43.0 ± 12.0 years and initial body mass index 48.0 ± 7.9 vs. 42.9 ± 7.3 kg/m2 , p < .001). NHS patients were more likely to have obesity-related complications compared to self-pay patients: prevalence of Type 2 diabetes mellitus 27.7% versus 8.3%, hypertension 37.1% versus 20.1%, obstructive sleep apnoea 27.4% versus 8.9%, severely impaired functional status 19.3% versus 13.9%, musculoskeletal pain 32.5% versus 20.1% and being on medication for depression 31.0% versus 25.9%, respectively (all p < .001). Gastric bypass was the most commonly performed primary NHS bariatric operation 57.2%, but sleeve gastrectomy predominated in self-pay patients 48.7% (both p < .001). In contrast to self-pay patients, NHS patients are receiving bariatric surgery only once they are older and at a much more advanced stage of obesity-related disease complications.

BACKGROUND AND STUDY AIMS: Ileorectal anastomosis (IRA) is one option for restoring bowel continuity in patients who have undergone subtotal colectomy for ulcerative colitis (UC). This systematic review aims to assess short- and long-term outcomes after IRA for UC, including anastomotic leak rates, IRA failure (as defined by conversion to pouch or end stoma), cancer risk in the rectal remnant, and quality of life (QoL) post-IRA surgery. MATERIALS & METHODS: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis checklist was used to demonstrate the search strategy. A systematic review of PubMed, Embase, Cochrane library, and Google Scholar from 1946 to August 2022 was undertaken. RESULTS: This systematic review included 20 studies, representing 2538 patients who underwent IRA for UC. The mean age ranged from 25 to 36 years and the mean postoperative follow-up ranged between 7 and 22 years. The overall leak rate reported across 15 studies was 3.9 % (n = 35/907) ranging from 0 % to 16.7 %. The failure of IRA (requiring conversion to pouch or end stoma) as reported across 18 of the studies was 20.4 % (n = 498/2447). The risk of developing cancer in the remaining rectal stump following IRA was reported by 14 studies and was accumulatively 2.4 % (n = 30/1245). Five studies reported on patient QoL using a variety of different instruments and 66.0 % of patients (n = 235/356) reported a "high" QoL score. CONCLUSION: IRA was associated with a relatively low leak rate and a low risk of colorectal cancer in the rectal remnant. However, it does carry a significant failure rate which invariably requires conversion to an end stoma or the formation of an ileoanal pouch. IRA provided a QoL to most of the patients.

AIM: Bariatric-metabolic surgery is approved by the National Institute of Health and Care Excellence (NICE) for people with severe obesity and type 2 diabetes (T2DM) (including class 1 obesity after 2014). This study analysed baseline characteristics, disease severity and operations undertaken in people with obesity and T2DM undergoing bariatric-metabolic surgery in the UK National Health Service (NHS) compared to those without T2DM. METHODS: Baseline characteristics, trends over time and operations undertaken were analysed for people undergoing primary bariatric-metabolic surgery in the NHS using the National Bariatric Surgical Registry (NBSR) for 11 years from 2009 to 2019. Clinical practice before and after the publication of the NICE guidance (2014) was examined. Multivariate logistic regression was used to determine associations with T2DM status and the procedure undertaken. RESULTS: 14,948/51,715 (28.9%) participants had T2DM, with 10,626 (71.1%) on oral hypoglycaemics, 4322 (28.9%) on insulin/other injectables, and with T2DM diagnosed 10+ years before surgery in 3876 (25.9%). Participants with T2DM, compared to those without T2DM, were associated with older age (p < 0.001), male sex (p < 0.001), poorer functional status (p < 0.001), dyslipidaemia (OR: 3.58 (CI: 3.39-3.79); p < 0.001), hypertension (OR: 2.32 (2.19-2.45); p < 0.001) and liver disease (OR: 1.73 (1.58-1.90); p < 0.001), but no difference in body mass index was noted. Fewer people receiving bariatric-metabolic surgery after 2015 had T2DM (p < 0.001), although a very small percentage increase of those with class I obesity and T2DM was noted. Gastric bypass was the commonest operation overall. T2DM status was associated with selection for gastric bypass compared to sleeve gastrectomy (p < 0.001). CONCLUSION: NHS bariatric-metabolic surgery is used for people with T2DM much later in the disease process when it is less effective. National guidance on bariatric-metabolic surgery and data from multiple RCTs have had little impact on clinical practice.

BACKGROUND: Recent evidence has emerged reporting atypical clinical symptoms of the novel coronavirus (COVID-19). There is a sparsity of existing studies examining COVID-19-related abdominal pain and the role of investigative imaging for the virus in these patients. Study aims were to determine COVID-19 incidence in those with acute abdominal pain in the absence of respiratory symptoms and to assess the diagnostic performance of CT thoracic imaging in such patients. METHODS: Retrospective analysis of all consecutive patients admitted to our emergency general surgical unit between 1st March 2020 and 31st May 2020 was performed. In adherence with national guidelines, all patients underwent nasal and oro-pharyngeal COVID-19 RT-PCR swabs as well as thoracic and abdominal computed tomography (CT) on admission. RESULTS: From 112 patients admitted with acute abdominal pain in the absence of respiratory symptoms, 16 (14.3%) tested positive for COVID-19 on RT-PCR swab testing. Overall, 50% (8/16) of these patients had no intra-abdominal pathology on CT. The sensitivity and specificity of CT thoracic imaging for diagnosing COVID-19 was 43.8% and 91.7%, respectively. Patients with positive COVID-19 swabs had higher C-reactive protein levels, lower potassium levels and a higher proportion of those with a low lymphocyte count. DISCUSSION: One in seven patients with abdominal pain without any respiratory symptoms tested positive for COVID-19. Half of these patients represented COVID-19 manifesting primarily as acute abdominal pain. Combined swab testing and CT imaging should be performed in all abdominal pain presentations due to the varying diagnostic performance of thoracic CT in diagnosing COVID-19.

Purpose: To elucidate the indication, presentation, demographics, Stanford classification, technical efficacy, morbidity, mortality and long term patency of Wallstent for superior vena cava (SVC) syndrome. Materials and Methods: A systematic review of literature in Pubmed and Embase, CINAHL and Cochrane Library in accordance to PRIMSA was conducted. Retrieval and extraction was performed by two independent reviewers with inter-rater reliability test. The hierarchy of the evidence was assessed through the National Institute for Health and Care Excellence Checklist. Data was subjected to pooled prevalence analysis, Cox regression, Kaplan-Meir survival and test of probability using log rank analytics. This review is registered with International prospective register of systematic review: CRD42021271009. Results: A total of n=701 individuals with n=930 stents with median age of 60 (interquartile range (IQR): 26-89) years and male predominance 3.5 : 1 were identified in n=30 articles. The most common venographic classification was Stanford type II (n=344, 50%) and complete symptomatic resolution was achieved in 48 h. The 30-day morbidity was (n=62, 8%) and mortality was (n=21, 3%). Female gender was associated with higher 30-day morbidity (p<0.03). The cumulative median patency of Wallstent for non-malignant aetiology was [550 days (IQR: 14-1080) vs. 120 days (IQR: 0-925)] for malignancy (p<0.03). Conclusion: The use of Wallstent for resolution of malignancy induced SVC syndrome as a first line therapy is feasible and associated with low mortality. Their use for non-malignant aetiology demands a more in depth review and advocates further investigation.
RESUMO
BACKGROUND: Access to community rectoscopy might help to ease the burden on hospital services and reduce costs for the NHS. To assess this, a prospective multicentre observational phase I feasibility study of a novel digital rectoscope and telestration software for the triage of lower gastrointestinal (GI) symptoms was undertaken. AIM: To determine if digital rectoscopy is feasible, acceptable, and clinically safe. DESIGN & SETTING: Evaluation of clinician case reports and patient questionnaires from patients recruited from five primary care centres. METHOD: Adults meeting 2-week wait (2WW) criteria for suspected lower GI cancer, suspected new diagnosis, or flare-up of inflammatory bowel disease (IBD) were enrolled. Examinations were performed by primary care practitioners using the LumenEye rectoscope. The CHiP platform allowed immediate remote review by secondary care. A prospective analysis was performed of patient and clinician experiences, diagnostic accuracy, and cost. RESULTS: A total of 114 patients were recruited and 110 underwent the procedure (46 [42%] females and 64 [58%] males). No serious adverse events were reported. Eighty-two (74.5%) patients reported that examination was more comfortable than expected, while 104 (94.5%) felt the intervention was most convenient if delivered in the community. Clinicians were confident of their assessment in 100 (87.7%) examinations. Forty-eight (42.1%) patients subsequently underwent colonoscopy, flexible sigmoidoscopy, or computed tomography virtual colonoscopy (CTVC). The overall sensitivity and specificity of LumenEye in identifying rectal pathology was 90.0% and 88.9%. It was 100% and 100% for cancer, and 83.3% and 97.8% for polyps. Following LumenEye examination, 19 (17.3%) patients were discharged, with projected savings of 11 305 GBP. CONCLUSION: Digital rectoscopy in primary care is safe, acceptable, and can reduce referrals. A phase III randomised controlled trial is indicated to define its utility in reducing the burden on hospital diagnostic services.
RESUMO
BACKGROUND: Limited robust evidence exists comparing outcomes following completely minimally invasive oesophagectomy (CMIO) to hybrid oesophagectomy (HO) in the treatment of resectable oesophageal and gastro-oesophageal junctional (GOJ) cancer. This multi-centre study aims to assess postoperative morbidity between HO and CMIO according to the full Esophagectomy Complications Consensus Group (ECCG) complication platform. METHODS: All consecutive patients undergoing an Ivor-Lewis HO or Ivor-Lewis CMIO for cancer between 2016 and 2018 in three UK tertiary centres were included. The primary study outcome was 30-day overall complications, evaluated by the ECCG complication subgroups. Secondary outcomes included survival outcomes and perioperative parameters between the two approaches. RESULTS: Of the 382 patients included, 228 (59.7%) patients had HOs and 154 (40.3%) patients had CMIOs with no inter-group baseline differences. Patients undergoing CMIO experienced less 30-day postoperative complications compared to those under undergoing HO (43.5% vs 57.0%, p = 0.010). ECCG defined pulmonary and infective complications were less frequent in the CMIO group. Anastomotic leak rates and oncological outcomes were similar between the two groups. Independent predictors of 30-day postoperative complications include surgical approach with HO and high ASA grade on multivariable analysis. CONCLUSIONS: Ivor-Lewis CMIO demonstrates superior short-term surgical outcomes when compared to Ivor-Lewis HO with no compromise in oncological feasibility. Anastomotic leak rates were equivalent between both groups. A robust randomised controlled trial is required to validate the findings of this study.

MATERIAL AND METHODS: A systematic review of literature from the database inception to January 2021 in PubMed and Embase, CINAHL and Cochrane Library in accordance to PRISMA was conducted. Retrieval and extraction was performed by two independent reviewers. The hierarchy of the evidence was assessed through the National Institute for Health and Care Excellence Checklist. Data were subjected to pooled prevalence analysis, Kaplan-Meier survival and test of probability using log-rank analysis. This review is registered with International Prospective Register of Systematic Reviews: RD42021231314. RESULTS: 82 studies with n = 123 cases met the inclusion criterion. Abdominal (45%) aorta was the commonest anatomical site with female predominance in ascending aorta (4:1) and aortic arch (2:1). The longest survival was in the ascending aorta and the shortest in the abdominal aorta [540 (interquartile range [IQR], 7-1560 days vs. 180 (IQR, 1-5730 days)], respectively. The overall median survival was 210 days (IQR, 1-5730 days) or 7 months. Lack of metastasis (47%) was a marker of longer survival (p < 0.03) irrespective of other attributes. CONCLUSION: The pathophysiology appears to be a trend of increasing fatigue, fever and weight loss associated with segmental dysfunction of the aorta projecting occlusive or destructive phenotypes. Computed tomography angiography features of volume-occupying, bulky, polypoid (intraluminal), protrusive vegetation, hyper vascular without atherosclerotic lesions are extremely suggestive of PA of the aorta at 5th and 6th decades of life.

INTRODUCTION: Colorectal anastomotic leaks (AL) are associated with high morbidity and mortality. Management of AL and its intra-operative decision making is often difficult. The aim of this multi-centre study is to explore different management strategies, including different surgical options, and analyse rates and patterns of failure of initial management. METHODS: All consecutive patients who had a confirmed AL after elective colorectal resections from 1st January 2014 to 31st December 2019 were included at seven hospitals across the East of England Region. Morbidity (length of stay, and failures) and mortality were compared across the different management strategies, and survival analyses were performed (Clinicaltrials.gov ID: NCT05000580). RESULTS: Across all seven hospitals, a total of 3391 elective resection were done during the study period. 201 (5.9%) consecutive patients with confirmed AL were included. The initial treatment was conservative in 102(50.7%). 19 patients (9.5%) had a radiological procedure, 80 (39.8%) of patients required surgery as an initial treatment post AL. Of those who initially did not have a surgical intervention (n = 121), 10% (n = 12/121) eventually required laparotomy, 2 additional patients required transanal drainage. Ultimately 45.8% (n = 92/201) of the whole population eventually required a laparotomy. Patients managed conservatively had a shorter LOS when compared to either radiological drainage or surgical patients. Patients with a defunctioning stoma are more likely to have a successful conservative management and shorter LOS. 90-day mortality across the entire population was 8.1%. There were no significant differences in mortality or long-terms survival between the different initial treatment modalities or whether the leak was right or left sided. CONCLUSION: Despite initial conservative, antibiotic and radiological intervention being successful in the majority of patients, two out of five patients will still require a laparotomy and over a quarter of patients will have an end stoma.
