RESUMO
AIM: The impact of surgeon volume on 18-month unclosed ileostomy rates after rectal cancer surgery has not been fully explored. The aim of this study was to describe the effect of surgeon volume and evaluate factors predictive of an unclosed ileostomy. METHOD: Patients undergoing anterior resection with a diverting ileostomy for rectal cancer from March 2004 to October 2018 were identified from a prospectively maintained database. The unclosed ileostomy rate was determined by those with an unclosed ileostomy at 18 months. High- and low-volume surgeons (HVS and LVS, respectively) were classed as those performing five or more or fewer than five rectal cancer resections per year, respectively. Data on sex, age, American Society of Anesthesiologists grade, neoadjuvant chemoradiotherapy (CRT), tumour height, T-stage, anastomotic leak, surgical approach and adjuvant chemotherapy were also collected. Factors predictive of an unclosed ileostomy at 18 months were explored using a multivariate binary logistic regression analysis. RESULTS: A total of 415 patients (62.4% male) with a median age of 67 were eligible for analysis. Of these, 115 (27.7%) had an unclosed ileostomy at 18 months. HVS had an unclosed ileostomy rate of 24.6% (72/292) compared with 34.9% (43/123) for LVS. Volume was associated with an unclosed ileostomy in univariable analysis (p = 0.032) but not in multivariate analysis (OR 1.75, 95% CI 0.92-3.32, p = 0.08). Independent factors predictive of an unclosed ileostomy were anastomotic leak (OR 10.41, 3.95-27.0, p < 0.01), adjuvant chemotherapy (OR 2.23, 1.24-3.96, p < 0.01) and neoadjuvant CRT (OR 2.16, 1.15-5.75, p = 0.01). CONCLUSION: LVS were associated with a higher unclosed ileostomy at 18 months compared with HVS. This study adds further weight to the call for adoption of a minimum annual case threshold in rectal cancer surgery.

BACKGROUND: Diverticular disease accounts for significant morbidity and mortality and may take the form of recurrent episodes of acute diverticulitis. The role of elective surgery is not clearly defined. OBJECTIVE: This study aimed to define the rate of hospital admission for recurrent acute diverticulitis and risk factors associated with recurrence and surgery. DESIGN: This is a retrospective population-based cohort study. SETTINGS: National Health Service hospital admissions for acute diverticulitis in England between April 2006 and March 2011 were reviewed. PATIENTS: Hospital Episode Statistics data identified adult patients with the first episode of acute diverticulitis (index admission), and then identified recurrent admissions and elective or emergency surgery for acute diverticulitis during a minimum follow-up period of 4 years. Exclusion criteria included previous diagnoses of acute diverticulitis, colorectal cancer, or GI bleeding, and prior colectomy or surgery or death during the index admission. INTERVENTIONS: There were no interventions. MAIN OUTCOME MEASURES: The primary outcomes measured were recurrent admissions for acute diverticulitis and patients requiring either elective or emergency surgery during the study period. RESULTS: Some 65,162 patients were identified with the first episode of acute diverticulitis. The rate of hospital admission for recurrent acute diverticulitis was 11.2%. A logistic regression model examined factors associated with recurrent acute diverticulitis and surgery: patient age, female sex, smoking, obesity, comorbidity score >20, dyslipidemia, and complicated acute diverticulitis increased the risk of recurrent acute diverticulitis. There was an inverse relationship between patient age and recurrence. Similar factors were associated with elective and emergency surgery. LIMITATIONS: The cases of acute diverticulitis required inpatient management and the use of Hospital Episode Statistics, relying on the accuracy of diagnostic coding. CONCLUSIONS: This is the largest study assessing the rates of hospital admission for recurrent acute diverticulitis. Knowledge of the rate and risk factors for recurrent acute diverticulitis is required to aid discussion and decision making with patients regarding the need and timing of elective surgery. Some factors associated with recurrence are modifiable; therefore, weight reduction and smoking cessation can be championed. See Video Abstract at http://links.lww.com/DCR/A449.

BACKGROUND: Colon cancer is one of the most common cancers and the second most common cause of cancer mortality in Western societies. Population screening has been introduced as a means to reducing its impact; however, there are little or no data on the incidence of this disorder in the different populations that comprise the Canadian population. OBJECTIVE: To retrospectively determine the incidence of colorectal cancer in selected racial populations of British Columbia. METHODS: The British Columbia Cancer Agency database was used to retrieve information on the incidence of cancers occurring during the years 1994 to 1998, with the British Columbia and national population censuses used to derive the age-specific and age-standardized incidence rates of colorectal cancers. Surnames were used to identify the origin of individuals from South Asian and Chinese backgrounds. RESULTS: For the Caucasian Canadian (C) population, the weighted age-standardized incidence rate ranged from 51.99 per 100,000 in 1995, to 57.68 per 100,000 in 1998. For Chinese Canadians (CC), the range was 39.2 per 100,000 in 1996, to 31.2 per 100,000 in 1998. For South Asian Canadians (SAC), the range was 7.40 per 100,000 in 1994, to 24.85 per 100,000 in 1998. The RR for the development of cancer were significantly different when comparing C versus CC (RR 1.9; 95% CI 1.58 to 2.31; P<0.001), C versus SAC (RR 7.1; 95% CI 4.20 to 12.0; P<0.0001) and CC versus SAC (RR 3.7; 95% CI 2.14 to 6.5; P<0.0001). CONCLUSIONS: Significant differences in the incidence of colorectal cancers have been defined for the first time in various racial subgroups in British Columbia. This finding may have important implications for both screening and understanding of the environmental factors influencing the biology of these lesions. Because SAC have among the highest incidence of atherosclerotic heart disease and diabetes, it suggests that unidentified genetic and/or environmental protective factors are capable of countering the traditionally recognized risk of high saturated fat intake for the development of colorectal cancer.

OBJECTIVE: To compare one-year outcomes of primary overlap versus end-to-end repair of the external anal sphincter after acute obstetric anal sphincter injury. METHODS: Women who sustained third-degree (3b = greater than 50% external anal sphincter thickness, 3c = internal sphincter injury) or fourth-degree (including anorectal epithelium) perineal tears were randomly allocated to either immediate primary overlap or end-to-end repair. They were prospectively followed up for 12 months postrepair with serial questionnaires. The primary outcome was fecal incontinence at 12 months. Secondary outcomes were fecal urgency, flatus incontinence, perineal pain, dyspareunia, quality of life, and improvement of anal incontinence symptoms. RESULTS: Thirty-two women were randomized to each group. At 12 months, 24% (6/25) in the end-to-end and none in the overlap group reported fecal incontinence (P = .009, relative risk [RR] 0.07, 95% confidence interval [CI] 0.00-1.21, number needed to treat 4.2). Fecal urgency at 12 months was reported by 32% (8/25) in the end-to-end and 3.7% (1/27) in the overlap group (P = .02, RR 0.12, 95% CI 0.02-0.86, number needed to treat 3.6). There were no significant differences in dyspareunia and quality of life between the groups. At 12 months, 20% (5/25) reported perineal pain in the end-to-end and none in the overlap group (P = .04, RR 0.08, 95% CI 0.00-1.45, number needed to treat 5). During 12 months, 16% (4/25) in the end-to-end and none in the overlap group reported deterioration of defecatory symptoms (P = .01). CONCLUSION: Primary overlap repair of the external anal sphincter is associated with a significantly lower incidence of fecal incontinence, urgency, and perineal pain. When symptoms do develop, they appear to remain unchanged or deteriorate in the end-to-end group but improve in the overlap group. LEVEL OF EVIDENCE: I.

OBJECTIVE: To quantify the proportion of requests for colonoscopy that are performed as flexible sigmoidoscopy and documented reasons for this in ordinary UK hospital practice. To determine the effect these requests have on colonoscopy completion rate if they are included in the denominator of the calculated rate by individual endoscopist. DESIGN: Retrospective study of 22â months flexible sigmoidoscopy practice at a major UK teaching hospital. All flexible sigmoidoscopies performed had their associated request form examined. SETTING: UK NHS University Hospital. PATIENTS: All patients receiving outpatient flexible sigmoidoscopy from January 2013 to October 2014 with no exclusions. INTERVENTION: Conversion of colonoscopy to flexible sigmoidoscopy. MAIN OUTCOME MEASURES: Conversion of colonoscopy to flexible sigmoidoscopy, reason for conversion and adjusted colonoscopy completion rate. RESULTS: 71 of the 3526 flexible sigmoidoscopies performed (2.0%), representing 71 of 5905 colonoscopy requests (1.2%). Conversion reason was noted only in 26 (37%) of converted cases. Adjustment of colonoscopy completion rate to include conversions pushed four of our unit's 22 endoscopists below the UK national 90% standard. CONCLUSIONS: Conversion to flexible sigmoidoscopy occurs in 1.2% of patients originally booked for colonoscopy. The reason for this conversion is often unqualified and may be inappropriate. Conversion can affect the colonoscopy completion rate, and therefore, should be included in endoscopists' overall performance statistics.
RESUMO
BACKGROUND: Optimal surgical intervention for low-grade haemorrhoids is unknown. Rubber band ligation (RBL) is probably the most common intervention. Haemorrhoidal artery ligation (HAL) is a novel alternative that may be more efficacious. OBJECTIVE: The comparison of HAL with RBL for the treatment of grade II/III haemorrhoids. DESIGN: A multicentre, parallel-group randomised controlled trial. PERSPECTIVE: UK NHS and Personal Social Services. SETTING: 17 NHS Trusts. PARTICIPANTS: Patients aged ≥ 18 years presenting with grade II/III (second- and third-degree) haemorrhoids, including those who have undergone previous RBL. INTERVENTIONS: HAL with Doppler probe compared with RBL. OUTCOMES: Primary outcome - recurrence at 1 year post procedure; secondary outcomes - recurrence at 6 weeks; haemorrhoid severity score; European Quality of Life-5 Dimensions, 5-level version (EQ-5D-5L); Vaizey incontinence score; pain assessment; complications; and cost-effectiveness. RESULTS: A total of 370 participants entered the trial. At 1 year post procedure, 30% of the HAL group had evidence of recurrence compared with 49% after RBL [adjusted odds ratio (OR) = 2.23, 95% confidence interval (CI) 1.42 to 3.51; p = 0.0005]. The main reason for the difference was the number of extra procedures required to achieve improvement/cure. If a single HAL is compared with multiple RBLs then only 37.5% recurred in the RBL arm (adjusted OR 1.35, 95% CI 0.85 to 2.15; p = 0.20). Persistence of significant symptoms at 6 weeks was lower in both arms than at 1 year (9% HAL and 29% RBL), suggesting significant deterioration in both groups over the year. Symptom score, EQ-5D-5L and Vaizey score improved in both groups compared with baseline, but there was no difference between interventions. Pain was less severe and of shorter duration in the RBL group; most of the HAL group who had pain had mild to moderate pain, resolving by 3 weeks. Complications were low frequency and not significantly different between groups. It appeared that HAL was not cost-effective compared with RBL. In the base-case analysis, the difference in mean total costs was £1027 higher for HAL. Quality-adjusted life-years (QALYs) were higher for HAL; however, the difference was very small (0.01) resulting in an incremental cost-effectiveness ratio of £104,427 per additional QALY. CONCLUSIONS: At 1 year, although HAL resulted in fewer recurrences, recurrence was similar to repeat RBL. Symptom scores, complications, EQ-5D-5L and continence score were no different, and patients had more pain in the early postoperative period after HAL. HAL is more expensive and unlikely to be cost-effective in terms of incremental cost per QALY. LIMITATIONS: Blinding of participants and site staff was not possible. FUTURE WORK: The incidence of recurrence may continue to increase with time. Further follow-up would add to the evidence regarding long-term clinical effectiveness and cost-effectiveness. The polysymptomatic nature of haemorrhoidal disease requires a validated scoring system, and the data from this trial will allow further assessment of validity of such a system. These data add to the literature regarding treatment of grade II/III haemorrhoids. The results dovetail with results from the eTHoS study [Watson AJM, Hudson J, Wood J, Kilonzo M, Brown SR, McDonald A, et al. Comparison of stapled haemorrhoidopexy with traditional excisional surgery for haemorrhoidal disease (eTHoS): a pragmatic, multicentre, randomised controlled trial. Lancet 2016, in press.] comparing stapled haemorrhoidectomy with excisional haemorrhoidectomy. Combined results will allow expansion of analysis, allowing surgeons to tailor their treatment options to individual patients. TRIAL REGISTRATION: Current Controlled Trials ISRCTN41394716.

BACKGROUND: Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) may have an increased risk of developing colorectal cancer (CRC) after liver transplantation (LT). We evaluated our patients with PSC after LT to identify risk factors for CRC and its impact on survival. PATIENTS AND METHODS: A total of 152 patients (108 men, 100 with IBD) with PSC who underwent 173 LTs between 1986 and May 2000 were analyzed in three groups: (1) PSC without IBD (n=52); (2) PSC with colectomy (pre-LT and at LT) (n=17, colectomy pre-LT in 13 and simultaneous colectomy at LT in four); and (3) PSC with IBD and an intact colon (n=83). The following factors were studied: age, gender, liver, and renal biochemistry, international normalized ratio, Child-Pugh stage, operative time, blood use, hospital stay, immunosuppression, risk of CRC, retransplantation rate, and mortality. RESULTS: The incidence of CRC after LT was 5.3% (8/152) compared with 0.6% (7/1,184) in non-PSC cases (P<0.001). All CRCs in the PSC group were in patients with IBD and an intact colon. The cumulative risk of developing CRC in the 83 patients with an intact colon and IBD was 14% and 17% after 5 and 10 years, respectively (PSC non-IBD group 0% risk after 10 years, P<0.06). The multivariate analysis showed three significant variables related to the risk of developing CRC: colonic dysplasia after LT (P<0.0003), duration of colitis more than 10 years (P<0.002), and pancolitis (P<0.004). The cause of death in patients with CRC was cancer related in 75% of cases with a reduced 5-year survival of 55% versus 75% without CRC (not significant). CONCLUSION: Patients with PSC undergoing LT with a long history of ulcerative colitis and pancolitis have an increased risk of developing CRC with reduced survival. We advocate long-term aggressive colonic surveillance and colectomy in selected high-risk patients with longstanding severe colitis.

OBJECTIVE: To compare the incidence and severity of anal incontinence in primiparas after cesarean delivery versus spontaneous vaginal delivery. METHODS: A total of 184 primiparas who delivered by cesarean (104 emergency, 80 elective) and 100 who delivered vaginally were interviewed 10 +/- 2 months postpartum. A comprehensive bowel function questionnaire was completed. Bowel-specific questions included bowel habits, laxative use, urgency, flatus, urge and passive incontinence, soiling, and pad use, before and during pregnancy and postpartum. Obstetric details were confirmed from obstetric records. RESULTS: Anal incontinence was first present in nine (5%) mothers after cesarean delivery and eight (8%) after vaginal delivery (relative risk 0.611, 95% confidence interval 0.25, 1.53). Severe symptoms necessitating pad use affected two (3%) mothers after elective cesarean and one (1%) after vaginal delivery. Two (3%) mothers after elective cesarean, one (1%) after emergency cesarean, and two (2%) after vaginal delivery had at least two symptoms. Anal incontinence followed prelabor emergency cesarean in two mothers. Of the 22 mothers who sustained a second-degree tear, five (23%) had new anal incontinence compared with only one (3%) of 40 mothers with an intact perineum (Fisher exact test value = 9.697, P =.014). CONCLUSION: Because severe anal incontinence followed elective and prelabor emergency cesarean, it seems that pregnancy itself can lead to pelvic floor disorders. A high incidence of anal incontinence is associated with a second-degree tear. Measures to detect and reduce postpartum anal incontinence should target all pregnant women and mothers, even after prelabor cesarean delivery.

BACKGROUND: We aim to establish the evidence base for the recognition and management of obstetric anal sphincter injury (OASI) and to compare this with current practice amongst UK obstetricians and coloproctologists. METHODS: A systematic review of the literature and a postal questionnaire survey of consultant obstetricians, trainee obstetricians and consultant coloproctologists was carried out. RESULTS: We found a wide variation in experience of repairing acute anal sphincter injury. The group with largest experience were consultant obstetricians (46.5% undertaking > or = 5 repairs/year), whilst only 10% of responding colorectal surgeons had similar levels of experience (p < 0.001). There was extensive misunderstanding in terms of the definition of obstetric anal sphincter injuries. Overall, trainees had a greater knowledge of the correct classification (p < 0.01). Observational studies suggest that a new 'overlap' repair using PDS sutures with antibiotic cover gives better functional results. However, our literature search found only one randomised controlled trial (RCT) on the technique of repair of OASI, which showed no difference in incidence of anal incontinence at three months. Despite this, there was a wide variation in practice, with 337(50%) consultants, 82 (55%) trainees and 80 (89%) coloproctologists already using the 'overlap' method for repair of a torn EAS (p < 0.001). Although over 50% of colorectal surgeons would undertake long-term follow-up of their patients, this was the practice of less than 10% of obstetricians (p < 0.001). Whilst over 70% of coloproctologists would recommend an elective caesarean section in a subsequent pregnancy, only 22% of obstetric consultants and 14% of trainees (p < 0.001). CONCLUSION: An agreed classification of OASI, development of national guidelines, formalised training, multidisciplinary management and further definitive research is strongly recommended.

INTRODUCTION: The unplanned re-admission rate is a national key performance indicator employed by the UK Department of Health. An adjusted figure, based on admission information data on the hospital electronic Patient Administration System (PAS), but adjusted to take account of case mix is compared with a calculated 'expected'. While previous studies have investigated unplanned re-admission rates in age-, procedure- or process-specific conditions, 'all-cause' general surgical re-admission rate is yet to be studied. The aim of this study was to assess the accuracy of hospital unplanned re-admission data, and identify patterns or possible causes of unplanned general surgical re-admissions. PATIENTS AND METHODS: Retrospective audit of case note records of all patients identified from the hospital electronic PAS as unplanned, general surgical re-admissions over a period of 4 consecutive months. RESULTS: Of all 161 re-admissions in this study, 46 (29%) were unrelated to the index admission, planned or involved patient self-discharge during the index admission. Of the 'genuine', unplanned re-admissions, 80 (78%) followed an emergency index admission, 58 (56%) had chronic or recurrent symptoms, for which 26 (25%) were on waiting lists. Fourteen (14%) were multiple admissions of 4 patients, while 8 (8%) re-admissions required further surgery for significant postoperative complications. CONCLUSIONS: Unplanned. general surgical re-admission rates collated from hospital PAS systems may be inaccurate. Nearly half of 'genuine', unplanned re-admissions involved patients with chronic and/or recurrent symptoms, which are predictable and may be preventable. Significant postoperative complications accounted for few re-admissions in this study.

This is a report of the first case of adenocarcinoma arising in an ileal pouch after proctocolectomy for ulcerative colitis in a patient who had also undergone orthotopic liver transplantation for primary sclerosing cholangitis. Previously reported cases of adenocarcinoma developing after formation of an ileoanal pouch are reviewed as is the evidence for neoplastic transformation of the ileal mucosa. The risk factors for the development of colorectal cancer in patients with ulcerative colitis and the possibility that these may be risk factors for the development of pouch malignancy are discussed. We conclude that this patient exemplifies a small group of patients who may be at increased risk of developing pouch malignancy and need endoscopic follow-up. There is also the need for longer-term follow-up data to determine the risk of this rare and potentially devastating complication of restorative proctocolectomy.
