Abstract
AIM Squamous cell carcinomas of the anus are normally treated with synchronous chemoradiotherapy (CRT). Small, localized anal margin tumours may be adequately treated by local excision (LE) alone. This study aims to investigate the outcomes of patients with anal margin tumours treated with LE alone, reserving the use of CRT for salvage on local recurrence (LR). METHODS Patients with small, localized (stage I/IIA) anal margin tumours treated by LE from October 1999 to September 2018 were identified. The effect of tumour size and resection margin on LR risk was analysed. Outcomes of overall survival and disease-free survival were measured. RESULTS Fifty-five patients with anal margin tumours were identified. Overall 5-year LR, overall survival and disease-free survival rates were 8%, 86% and 82% respectively. Of the seven LRs, five were successfully salvaged with CRT with no further recurrence and two were not fit for CRT. Resection margins in non-fragmented tumours and tumour size did not significantly influence LR risk. CONCLUSIONS Most small, localized anal margin tumours can be adequately treated by LE alone with low LR rates. Most patients who developed LR were salvaged using CRT, with no cancer-related deaths reported.

Abstract
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.

Abstract
Abstract
Background
This paper describes the development and validation of an electronic personal assessment questionnaire for vascular conditions (ePAQ-VAS) that captures the symptomatology, quality of life and clinically relevant data of patients presenting to vascular services.
Methods
A two-stage survey was conducted in patients attending a tertiary vascular department. Patients completed the ePAQ-VAS remotely online, or on site using an electronic tablet. In the first stage of the survey, the responses were used to perform confirmatory factor analysis to assess the construct validity and remove redundant items. The internal reliability of disease-specific scales was investigated. In the second stage of the survey, the acceptability, known-group validity, test–retest reliability, and responsiveness of ePAQ-VAS was assessed.
Results
In total, 721 patients completed ePAQ-VAS. Their mean(s.d.) age was 63·5(15·7) years and 468 (64·9 per cent) were men. Some 553 patients (76·7 per cent) completed the questionnaire in clinic and the remainder completed the questionnaire online. The results of the confirmatory factor analysis confirmed the conceptual model for ePAQ-VAS structure and eliminated six items. Internal reliability was acceptable for all the scales (Cronbach's α greater than 0·7). The test–retest reliability measured by the intraclass correlation coefficient ranged from 0·65 to 0·99. The results showed that the instrument was responsive over time with the standardized response mean ranging from 0·69 to 1·60.
Conclusion
ePAQ-VAS is a holistic data-collection process that is relevant to vascular service users and has potential to contribute to patient-focused care and the collection of aggregate data for service evaluation. A demonstration version of the final version of ePAQ can be viewed at http://demo-questionnaire.epaq.co.uk/home/project?id=VASC_1.7&page=1.

Abstract
BACKGROUND Closure of an abdominal stoma, a common elective operation, is associated with frequent complications; one of the commonest and impactful is incisional hernia formation. We aimed to investigate whether biological mesh (collagen tissue matrix) can safely reduce the incidence of incisional hernias at the stoma closure site. METHODS In this randomised controlled trial (ROCSS) done in 37 hospitals across three European countries (35 UK, one Denmark, one Netherlands), patients aged 18 years or older undergoing elective ileostomy or colostomy closure were randomly assigned using a computer-based algorithm in a 1:1 ratio to either biological mesh reinforcement or closure with sutures alone (control). Training in the novel technique was standardised across hospitals. Patients and outcome assessors were masked to treatment allocation. The primary outcome measure was occurrence of clinically detectable hernia 2 years after randomisation (intention to treat). A sample size of 790 patients was required to identify a 40% reduction (25% to 15%), with 90% power (15% drop-out rate). This study is registered with ClinicalTrials.gov, NCT02238964. FINDINGS Between Nov 28, 2012, and Nov 11, 2015, of 1286 screened patients, 790 were randomly assigned. 394 (50%) patients were randomly assigned to mesh closure and 396 (50%) to standard closure. In the mesh group, 373 (95%) of 394 patients successfully received mesh and in the control group, three patients received mesh. The clinically detectable hernia rate, the primary outcome, at 2 years was 12% (39 of 323) in the mesh group and 20% (64 of 327) in the control group (adjusted relative risk [RR] 0·62, 95% CI 0·43-0·90; p=0·012). In 455 patients for whom 1 year postoperative CT scans were available, there was a lower radiologically defined hernia rate in mesh versus control groups (20 [9%] of 229 vs 47 [21%] of 226, adjusted RR 0·42, 95% CI 0·26-0·69; p<0·001). There was also a reduction in symptomatic hernia (16%, 52 of 329 vs 19%, 64 of 331; adjusted relative risk 0·83, 0·60-1·16; p=0·29) and surgical reintervention (12%, 42 of 344 vs 16%, 54 of 346: adjusted relative risk 0·78, 0·54-1·13; p=0·19) at 2 years, but this result did not reach statistical significance. No significant differences were seen in wound infection rate, seroma rate, quality of life, pain scores, or serious adverse events. INTERPRETATION Reinforcement of the abdominal wall with a biological mesh at the time of stoma closure reduced clinically detectable incisional hernia within 24 months of surgery and with an acceptable safety profile. The results of this study support the use of biological mesh in stoma closure site reinforcement to reduce the early formation of incisional hernias.

Abstract
AIM Previous studies have raised concerns that the use of anti-tumour necrosis factor (anti-TNF) therapy in patients with ulcerative colitis (UC) undergoing surgery may increase the risk of postoperative complications. We have taken a population-based approach to investigate whether there is an association between anti-TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy. METHOD Hospital Episode Statistics (HES) data and procedural coding were used to identify all patients in England between April 2006 and March 2015 undergoing subtotal colectomy for UC. Patients were grouped into those who received anti-TNF therapy within 12 or 4 weeks of surgery and those who did not. The incidence of postoperative complications was evaluated by HES coding and compared between groups. RESULTS In all, 6225 UC patients underwent subtotal colectomy. 753 patients received anti-TNF therapy within 12 weeks prior to surgery (418 within 4 weeks). There was no difference in postoperative complications between groups although groups were not comparable for age and comorbidities. Logistic regression with complications as the outcome variable did not show any significant association between anti-TNF therapy and complications. Colectomy performed during an unplanned admission (vs planned admission) and smoking were associated with complications. CONCLUSION This large population-based study does not demonstrate any association between preoperative anti-TNF therapy and postoperative complications in UC patients undergoing subtotal colectomy. The only variables associated with complications were colectomy performed during an unplanned admission and smoking.

Abstract
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.

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 22 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.

Abstract
This 67-year-old woman, with numerous previous abdominal operations, presented to her general practitioner 3 years ago with generalised abdominal pain and diarrhoea. With unremarkable haematology tests and a CT scan at that time she was given the diagnosis of irritable bowel syndrome. During the next 3 years her symptoms continued intermittently and now associated with vomiting and weight loss. This time both a barium follow-through followed by a CT scan demonstrated a small bowel intussusception. A laparotomy was done but surprisingly no intussusception was found, only a single adhesional band which was divided. She was discharged 5-days postoperative but re-admitted 3 days later with abdominal discomfort, bloating and vomiting. A repeat CT scan again showed the presence of a small bowel intussusception and a second laparotomy was performed, this time demonstrating a jejuno-ileal intussusception which was reduced and resected with primary anastomosis. Her postoperative course was without incidents.

Abstract
Anal incontinence after childbirth is both distressing and disabling. A perineal trauma clinic was set up at the Birmingham Women's Hospital with an obstetrician, a urogynaecologist and a colorectal surgeon to improve the follow-up of women with obstetric anal sphincter injury or childbirth-precipitated anal incontinence. Fifty-five women attended the clinic. Forty-one had sustained a recognised obstetric anal sphincter injury at delivery and of these women, 61% were symptomatic with 22% leaking solid or liquid faeces. Fourteen women attended with anal incontinence who had not been recognised as sustaining an anal sphincter injury at the time of delivery. Eleven women were offered a secondary surgical repair of their anal sphincter defect. Seven accepted surgical treatment and 85% (six) were continent following surgery. A perineal trauma clinic offers an opportunity for early assessment and reduction of morbidity from childbirth-related anal incontinence.

Abstract
A wide range of symptoms are commonly ascribed to pelvic organ prolapse including pain, awareness of lump, bowel, bladder and sexual dysfunction. The aim of this work was to develop and validate an instrument to quantify symptoms related to pelvic organ prolapse. Consultation with symptomatic women and specialists in coloproctology, urology, gynaecology and sexual health resulted in a questionnaire with 25 questions. In total, 203 women participated in a psychometric testing of this instrument, 152 cases with prolapse and 51 controls without. The content validity, criterion validity, reliability and responsiveness of the questionnaire were evaluated. The questionnaire proved a reliable and valid instrument for the assessment of symptoms related to uterovaginal prolapse. It is also sensitive to change.

Abstract
Rectal squamous-cell carcinoma is a rare tumour with an incidence of less than 1 per 1000 cases. We report such a case treated with chemoradiotherapy. The patient developed a metastasis in the spleen and a further squamous tumour in the right colon, both of which were successfully resected. No histological evidence of recurrent rectal tumour has been found. Two years following presentation, the patient remains disease-free although symptomatic from a radiotherapy-induced stricture of the rectum.

Abstract
OBJECTIVE Faecal occult blood testing is being introduced for population screening in the United Kingdom. Flexible sigmoidoscopy may provide a viable alternative. The outcomes of the flexible sigmoidoscopy trial are awaited but the most obvious disadvantage is that only the lower third of the colon is examined and proximal pathology cannot be excluded. The relationship between proximal pathology and distal findings at flexible sigmoidoscopy is uncertain. The aim of this study was to determine the incidence of distal neoplasia in patients with confirmed proximal cancers of the colon. METHOD All confirmed proximal colonic cancers (defined as those proximal to the splenic flexure) were identified from a database of pathology specimens at a single centre between January 1999 and August 2006. A retrospective analysis of preoperative and peri-operative mucosal imaging (contrast enema, colonoscopy and CT colonography) was conducted to identify any distal neoplasia in these patients. RESULTS A total of 348 patients were identified. Pre- or peri-operative mucosal imaging was identified in 231 (66%) and 49 (21%) had distal neoplasia. Nineteen (8%) of these patients would have gone on to have a colonoscopy based on the UK flexible sigmoidoscopy trial protocol and 92% of the cohort would not have had a colonoscopy. CONCLUSION Nearly 80% of confirmed proximal cancers in our series did not have any demonstrable distal neoplasia. Only 8% of our cohort would have proceeded to colonoscopy. A very significant number of proximal cancers would not have been detected.

Abstract
OBJECTIVES To assess if mode of delivery is associated with increased symptoms of anal incontinence following childbirth. DESIGN Systematic review of all relevant studies in English. DATA SOURCES Medline, Embase, Cochrane Library, bibliographies of retrieved primary articles and consultation with experts. STUDY SELECTION AND DATA EXTRACTION Data were extracted on study characteristics, quality and results. Exposure to risk factors was compared between women with and without anal incontinence. Categorical data in 2 x 2 contingency tables were used to generate odds ratios. RESULTS Eighteen studies met the inclusion criteria with 12,237 participants. Women having any type of vaginal delivery compared with a caesarean section have an increased risk of developing symptoms of solid, liquid or flatus anal incontinence. The risk varies with the mode of delivery ranging from a doubled risk with a forceps delivery (OR 2.01, 95% CI 1.47-2.74, P < 0.0001) to a third increased risk for a spontaneous vaginal delivery (OR 1.32, 95% CI 1.04-1.68, P = 0.02). Instrumental deliveries also resulted in more symptoms of anal incontinence when compared with spontaneous vaginal delivery (OR 1.47, 95% CI 1.22-1.78). This was statistically significant for forceps deliveries alone (OR 1.5, 95% CI 1.19-1.89, P = 0.0006) but not for ventouse deliveries (OR 1.31, 95% CI 0.97-1.77, P = 0.08). When symptoms of solid and liquid anal incontinence alone were assessed, these trends persisted but were no longer statistically significant. CONCLUSION Symptoms of anal incontinence in the first year postpartum are associated with mode of delivery.

Abstract
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.

Abstract
OBJECTIVE The outcome of immediate repair of obstetric third-degree tears is poorly documented. Immediate repair may give better functional results than delayed repair because scarring is reduced. This aim of this prospective study was to examine the early outcome of immediate repair of third-degree tears. METHOD A total of 121 women who had immediate repair of obstetric third-degree tears underwent interview, anal ultrasonography and anorectal physiology. RESULTS At review, 79 (65%) were completely asymptomatic (score = 0), 23 (19%), had minor flatus incontinence or mild urgency causing no compromise to their quality of life (score 1-4), and 19 (16%) had clinically embarrassing faecal incontinence (score 5-24). Thirty-nine (32%) had an intact internal anal sphincter (IAS) and external anal sphincter (EAS) (i.e. a successful repair), eight (7%) had a defect in the IAS alone but the EAS was intact (i.e. a successful repair but a residual IAS defect), 43 (35%) had a residual defect in the EAS alone (IAS intact) and 31 (26%) had a persistent defect in the IAS and EAS. Residual defects in either or both of the sphincters were associated with a significantly higher incidence of abnormal resting and squeeze anal pressures. Anal manometry had no correlation with symptoms. The highest proportion of severe incontinence was in those with an IAS defect alone (37%) and when there was a residual IAS and EAS defect (24%). Only 2 of 39 (5%) with an intact IAS and EAS had severe incontinence and only 8 of 43 (18%) with a residual EAS defect alone had severe faecal incontinence. CONCLUSION These results indicate a good outcome following immediate repair of third-degree obstetric tears and emphasize the role of the IAS in providing continence.

Abstract
To evaluate the criterion validity of the Birmingham Bowel and Urinary Symptoms Questionnaire (BBUSQ-22). Forty-four women presenting with urinary or bowel symptoms to a urogynaecology/functional bowel clinic, completed three disease-specific questionnaires (Birmingham Bowel and Urinary Symptoms Questionnaire, Sheffield Prolapse Symptoms Questionnaire and King's Health Questionnaire) and two generic questionnaires (SF-36 and EuroQol). Wilcoxon rank sum tests, Spearman's rank correlations and multiple regression analyses were undertaken. All clinically hypothesised correlations between the questionnaires' domains were found significant, and all domains hypothesised to be predictors of the BBUSQ-22 domains were proven to be prognostic, without explaining too much variability to doubt their uniqueness. The similarity among the measures has been proved without such relationships being too strong to call into question the distinctiveness of the concepts being measured. Overall, criterion validity is demonstrated, and the clinical usefulness of the addition this questionnaire makes to the area is highlighted.

Abstract
BACKGROUND Anal sphincter injury during childbirth - obstetric anal sphincter injuries (OASIS) - is associated with significant maternal morbidity including perineal pain, dyspareunia and anal incontinence. Anal incontinence affects women psychologically and physically. Many do not seek medical attention because of embarrassment. The two recognised methods for the repair of damaged external anal sphincter (EAS): are end-to-end (approximation) repair and overlap repair. OBJECTIVES To compare the effectiveness of overlap repair versus end-to-end repair following OASIS in reducing subsequent anal incontinence, perineal pain, dyspareunia and improving quality of life. SEARCH STRATEGY We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (30 January 2006), MEDLINE (January 1966 to 31 January 2006), EMBASE (January 1974 to 31 January 2006), SciSearch (January 1974 to 31 January 2006) and conference proceedings of obstetrics and gynaecology, surgery and coloproctology. SELECTION CRITERIA Randomised controlled trials comparing different techniques of immediate primary repair of EAS following OASIS. DATA COLLECTION AND ANALYSIS Trial quality was assessed independently by all authors. MAIN RESULTS Three eligible trials, of grade A quality, involving 279 women, were included. There was considerable heterogeneity in the outcome measures, time points and reported results. Meta-analyses showed that there was no statistically significant difference in perineal pain (relative risk (RR) 0.08, 95% confidence interval (CI) 0.00 to 1.45, one trial, 52 women), dyspareunia (RR 0.62, 95% CI 0.11 to 3.39, one trial, 52 women), flatus incontinence (RR 0.93, 95% CI 0.26 to 3.31, one trial, 52 women) and faecal incontinence (RR 0.07, 95% CI 0.00 to 1.21, one trial, 52 women) between the two repair techniques at 12 months but showed a statistically significantly lower incidence in faecal urgency (RR 0.12, 95% CI 0.02 to 0.86, one trial, 52 women) and lower anal incontinence score (weighted mean difference -1.70, 95% CI -3.03 to -0.37) in the overlap group. Overlap technique was also associated with a statistically significant lower risk of deterioration of anal incontinence symptoms over 12 months (RR 0.26, 95% CI 0.09 to 0.79, one trial, 41 women). There was no significant difference in quality of life. AUTHORS' CONCLUSIONS The limited data available show that compared to immediate primary end-to-end repair of OASIS, early primary overlap repair appears to be associated with lower risks for faecal urgency and anal incontinence symptoms. As the experience of the surgeon is not addressed in the three studies reviewed, it woudl be inappropriate to recommend one type of repair in favour of another.

Abstract
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.

Abstract
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.

Abstract
CONTEXT Anal incontinence is increasingly being recognised as a significant cause of physical and psychological morbidity with implications for healthcare provision within the community. There is controversy about which population groups are most disadvantaged by this chronic condition. OBJECTIVES The aim of this study was to evaluate the prevalence of this condition in the community according to age and gender, a systematic review was performed. DATA SOURCES Data were from Embase, Medline, bibliographies of known articles and contact with experts. STUDY SELECTION Studies were selected if data on anal incontinence could be extracted for participants over 15 years of age and living in the community. DATA EXTRACTION Data were extracted using a piloted form on participants' characteristics, study quality and incontinence rates. DATA SYNTHESIS Meta-analysis was used to combine data from multiple studies, and meta-regression evaluated the variation in rates according to age and gender in an analysis adjusted for study quality. RESULTS There were 29 studies (69,152 participants), of which 5 met over half of the high quality criteria. The rate of solid and liquid faecal incontinence among people aged 15-60 years was 0.8% [95% confidence interval (CI) 0.3-1.9] in men and 1.6% (95% CI 0.8-3.1) in women. In those aged over 60, this increased to 5.1% (95% CI 3.4-7.6) in men and 6.2% (95% CI 4.9-8.0) in women. Meta-regression showed that age had a significant influence on rates of solid and liquid faecal incontinence (p = 0.007), but not gender (p = 0.368) or study quality (p = 0.085). CONCLUSIONS The rate of solid and liquid faecal incontinence in older people is significantly higher than their younger counterparts. Gender differences in rates did not reach statistical significance.

OBJECTIVE To correlate anorectal function including rectal evacuation with anorectal physiology and endoanal ultrasound in women with third degree obstetric anal sphincter injury repaired at the time of delivery. PATIENTS AND METHODS Forty-four women with repaired third degree tears underwent anorectal physiology, anal ultrasonography and clinical assessment using the St. Marks incontinence score (0-24). Evacuatory disturbance was assessed by questionnaire. RESULTS There was a significant correlation between disturbed evacuation and incontinence symptoms (P=0.030). There was also a significant correlation between disturbed evacuation and internal anal sphincter (IAS) injury (P=0.026), but there was no correlation with external anal sphincter (EAS) injury. There was a correlation between disturbed evacuation and low resting anal pressure (P=0.013). Although IAS defects were associated with low anal pressure, only the correlation with Maximum Squeeze Pressure reached statistical significance (P=0.018). CONCLUSION Women with evacuatory disturbance after repaired third degree tears have a greater level of incontinence than those whose emptying is normal. This association is related to internal sphincter injury and reduced anal sphincter pressures.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
OBJECTIVE To develop a simple but sensitive instrument to evaluate and document symptoms of both bowel and urinary dysfunction in women. DESIGN A 22-item questionnaire covering a range of bowel and urinary symptoms was developed and underwent rigorous psychometric testing. SETTING The gynaecology departments of three hospitals, a urogynaecology clinic, a functional bowel clinic and a general practice. POPULATION Six hundred and thirty women, comprising four groups: 1. women awaiting hysterectomy (n = 379), 2. women following hysterectomy (n = 45), 3. women referred with functional bowel and/or urinary symptoms (n = 65), 4. asymptomatic controls (n = 141). MAIN OUTCOME MEASURES The content, construct and criterion validity, internal consistency, reliability and responsiveness of the questionnaire were measured. RESULTS Peer and patient reports and missing data patterns supported face and content validity. Factor analysis showed a clinically relevant four-factor structure with low content replication able to distinguish between patient groups, indicating good internal structure. Comparison with clinical, anorectal physiological, videoproctographic, transit time and urodynamic test results provide provisional indication of criterion validity. Key domain question analysis and Cronbach's alphas showed internal consistency. Kappa values demonstrated good test-retest reliability and key question correlation over time proved responsiveness. CONCLUSIONS Our findings support the suitability, clinical validity, reliability and responsiveness of a simple questionnaire, which is sensitive to the constraints of clinical practice. The authors recommend its use in health care evaluation research assessing the effects of pelvic surgery and as a useful tool in comparing treatment efficacy.

Abstract
BACKGROUND/AIMS To determine the long term outcome of cutting seton fistulotomy. MATERIALS AND METHOD An audit of fistula surgery using a cutting seton for cryptoglandular sepsis identified 32 patients treated between 1988-1996. The majority of the patients had a trans-sphincteric (26/32, 81%) fistula. RESULTS Fourteen (44%) had had previous fistula surgery before seton fistulotomy. Follow up was complete in 28 patients: 8 patients had recurrence (29%), 4 at a new site and 4 at the same site after apparent healing. Major incontinence was reported by 3 patients, minor incontinence by 7 and soiling by 5, but only 7 patients worsened after the cutting seton fistulotomy. Major incontinence was reported only by women who had a previous vaginal delivery. CONCLUSIONS Cutting setons do not always preserve continence in high trans-sphincteric and complex fistulas. Patients should be warned about a high recurrence rate after cutting seton fistulotomy. The use of a cutting seton for anterior fistulas in female patients with a history of vaginal delivery should be avoided because of the risk of incontinence.

Abstract
OBJECTIVE To compare the outcome after conventional sutured loop ileostomy closure with stapled ileostomy closure. SUMMARY BACKGROUND DATA A defunctioning loop ileostomy is now widely used in colorectal surgery. Subsequent closure may be associated with early complications, particularly bowel obstruction. The results of a preliminary nonrandomized study suggested that there was no significant difference in the rate of complications between sutured and stapled closure of loop ileostomy. METHODS One hundred forty-one consecutive patients who underwent loop ileostomy between 1993 and 1998 were randomized before surgery to either sutured or stapled loop ileostomy closure. Seventy-one patients had stapled closure and 70 had sutured closure. RESULTS Both groups were comparable in terms of age, sex, original operation, duration after original operation, and level of operating surgeon. Postoperative bowel obstruction occurred in 10/70 (14%) patients after sutured closure compared with 2/71 (3%) patients after stapled closure. Subgroup analysis of ileostomy closure in patients having an ileal pouch showed no significant difference in bowel obstruction between stapled and sutured closure (2/30 vs. 7/29). The incidence of other complications, readmissions, and reoperations did not differ between the two groups. The stapled closure was only 4 minutes quicker than sutured closure. The mean total hospital stay tended to be shorter after the stapled closure than the sutured closure, but this did not reach statistical significance. CONCLUSIONS Bowel obstruction occurred less frequently after stapled closure, but the mean hospital stay and readmission and reoperation rate did not significantly differ between the two groups.

Abstract
PURPOSE To clarify the clinical role of topical glyceryl trinitrate (GTN) in the management of anal fissures. PATIENTS AND METHODS Fifty-six consecutive patients with fissure-in-ano attending a colorectal clinic from April 1997 to May 1998 included 16 acute and 40 chronic anal fissures. Patients were instructed to apply 0.2% 0.5 g of GTN to the painful area of the anus. Patients were followed-up in the clinic at 4, 8 and 12 weeks, and by telephone interviews at a median follow up of 10 months. RESULTS Ten of 16 acute fissures (63%) were healed by 4 weeks and 13 (81%) by 8 weeks. Thirteen of 40 chronic fissures (33%) were healed by 8 weeks and 20 (50%) by 12 weeks. Seventeen patients (30%) underwent lateral sphincterotomy and all healed. There were five recurrences within 3 months of treatment with GTN. Thirty-four (61%) suffered from headaches, eight being severe headaches. None of the patients developed incontinence with GTN or lateral sphincterotomy. CONCLUSIONS Treatment of fissure-in-ano using GTN ointment was effective in up to 50% of patients with chronic anal fissure, and has the benefit of being repeatable if the fissure recurs. Patients should be aware that treatment is likely to take some months to be effective and is associated with significant side effects in up to 15% of patients.

Abstract
Experimental, clinical and epidemiological studies have implicated arachidonic acid and its metabolites as important mediators in colorectal carcinogenesis. Although arachidonic acid levels are increased in tumour membrane lipids, its availability for metabolic processes is not known. The activities of phospholipase A2 (PLA2) and diacylglycerol lipase therefore were assessed in tumour and normal mucosal specimens from 20 patients with colorectal cancer using 14C-radiolabelled substrates. The median (interquartile range) PLA2 activity was increased in tumour tissue (10.5 (6.0, 18.5) pmol arachidonic acid mg-1 h-1) compared with that in normal mucosa (5.6 (2.5, 8.5) pmol arachidonic acid mg-1 h-1) (P < 0.001, Wilcoxon signed rank test). Activity of diacylglycerol lipase was also greater in tumoral tissue (47.4 (21.6, 82.1) pmol arachidonic acid mg-1 h-1) than in mucosa (19.1 (9.4, 42.9) pmol arachidonic acid mg-1 h-1) (P < 0.005). There was no correlation between either PLA2 or diacylglycerol lipase activity and myeloperoxidase activity, suggesting that these increases were not directly attributable to tumour inflammatory cell infiltrate. Augmentation of arachidonic acid release in colorectal tumours may have implications for therapy.

Abstract
Dietary fat, arachidonic acid metabolism and lipid peroxidation have all been implicated in colorectal carcinogenesis. Fatty acids, prostaglandins (PGE2, PGF2 alpha) and malondialdehyde (MDA), the stable end-product of lipid peroxidation of polyunsaturated fatty acids (PUFAs), were studied in paired tumour and normal mucosa of 20 patients with colorectal cancer. Levels of arachidonic acid and total PUFAs were increased in the phospholipid fraction of tumours (P < 0.05). Levels of PGE2 and MDA were also higher in tumours (P < 0.001) and there was a significant correlation between MDA and PGE2 concentrations (rs = 0.69, P < 0.01). In contrast to previously reported in vitro studies, this work suggests that lipid peroxidation may be enhanced in human colorectal tumours. As PGE2 and MDA have been shown to be involved in carcinogenesis, these may be considered potential therapeutic targets for preventing or treating colorectal carcinoma.

Abstract
Previous studies have suggested reduced formation of secondary bile acids in patients with familial adenomatous polyposis (FAP). Developments in the collection, extraction and analysis of faecal bile acids as well as in the accurate diagnosis of FAP by DNA markers prompted reinvestigation of this hypothesis. The median (interquartile range (i.q.r.)) faecal bile acid concentration (3.69 (1.66-5.36) mumol per g dry weight) and daily excretion rate (60.5 (29-149) mumol per g per 24 h) in ten patients with FAP were similar to those of nine control subjects (3.31 (0.65-8.38) mumol per g dry weight and 30.1 (7.9-228) mumol per g per 24 h). Although the median (i.q.r.) concentration of only one bile acid (12-oxo-lithocholic acid) was significantly different between patients with FAP and controls (49 (34-70) versus 0 (0-20) nmol per g dry weight, P = 0.006), the derivatives of chenodeoxycholic acid (3.35 (1.76-5.32) versus 0.51 (0.13-2.37) mumol per g dry weight, P = 0.02) and cholic acid (1.63 (0.42-2.34) versus 0.80 (0.13-3.57) mumol per g dry weight, P = 0.006) were increased in those with polyposis. These results show increased bacterial biotransformation of faecal bile acids in patients with FAP.

Abstract
Each of 12 patients undergoing routine diagnostic upper gastrointestinal endoscopy received a single iv infusion of clindamycin phosphate 300 mg over 10 min. During the endoscopy, mucosal biopsies of the gastric antrum and fundus were obtained at varying times following the infusion. The clindamycin concentrations in the biopsies and in serum samples also taken after the infusion were determined. In addition, six healthy volunteers participated in a cross-over study on two different days. On both days, each subject received a single iv infusion of clindamycin phosphate 300 mg, immediately after which, gastric secretion was stimulated by iv pentagastrin (2 micrograms/kg/h) which was infused continuously over 150 min. On one of the study days, acid secretion by the stomach was inhibited by a slow iv infusion of ranitidine 50 mg. Clindamycin concentrations in gastric aspirates and serum samples collected after the infusion were determined. Concentrations of clindamycin in the fundal mucosa were significantly higher than the simultaneous serum concentrations (median ratio of tissue concentration to serum concentration, 2.0; P < 0.005) while concentrations in the antral mucosa were similar to those in serum (median ratio, 1.2; P = 0.65). Ranitidine significantly inhibited pentagastrin-stimulated acid secretion as demonstrated by a decrease in the volume of gastric aspirate when ranitidine was administered compared with when it was not administered (P < 0.01). Clindamycin concentrations in gastric juice were approximately one and one-half times higher than those in serum samples obtained simultaneously, both during stimulation of gastric acid secretion with pentagastrin and during inhibition of pentagastrin-stimulated acid secretion with ranitidine. Gastric juice concentrations of clindamycin were significantly higher following administration of ranitidine than after stimulation of gastric secretion by pentagastrin alone. Fundal mucosal and gastric juice concentrations of clindamycin exceeded the hypothetical maximum serum concentrations, indicating that accumulation in the stomach occurred against a concentration gradient.

Abstract
The development of colorectal polyps and cancer in patients with familial adenomatous polyposis (FAP) is directly linked to inactivation of the APC gene. Other, epigenetic, mechanisms may be involved in tumorigenesis and a previous study suggested that an intrinsic difference in the biliary bile acid profile of untreated patients with FAP persisted after colectomy. Gas chromatography and gas chromatography-mass spectrometry were used to examine the biliary bile acid profiles of four groups of patients with normal gallbladders: 20 patients with an intact colon comprising 12 with FAP and eight controls; and 26 patients after colectomy comprising 12 with FAP and 14 controls. Comparison of ten different bile acids from both amidate fractions (glycine and taurine) revealed a small increase in the molar percentage of a minor bile acid (12-oxolithocholic acid) in patients with FAP and an intact colon compared with the matching control group. Colectomy was associated with a dramatic reduction in levels of secondary bile acids but with little difference between patients with FAP and controls.

Abstract
There is now considerable evidence linking the severity of gallstone-associated acute pancreatitis with obstruction to both the bile duct and the pancreatic duct by "persisting" stones either because of continuous or repeated impaction, or repeated passage. Two prospective trials have shown endoscopic sphincterotomy to be superior to other forms of treatment, but only in severe cases, and general experience now extends to over 1000 cases so treated. Endoscopic sphincterotomy is also very effective in acute pancreatitis associated with acute cholangitis. Prophylactic endoscopic sphincterotomy may be of benefit in elderly patients in preference to prophylactic cholecystectomy. Yet to be fully explored is the role of this procedure in the early treatment of severe non-gallstone pancreatitis and in established pancreatic necrosis.

Abstract
Previous studies have suggested that patients with familial adenomatous polyposis (FAP) have increased faecal excretion of cholesterol but a reduction in cholesterol metabolites. It was consequently proposed that the degree of faecal cholesterol degradation could be used as a means of diagnosis. Developments in the extraction and analysis of faecal neutral sterols as well as the accurate means of diagnosing FAP by DNA analysis and indirect ophthalmoscopy has necessitated a re-examination of this proposal. Faecal neutral sterols were analysed in 10 patients with untreated FAP following a complete 5-day stool collection and compared with 9 healthy control subjects (including 4 siblings) closely matched for age and sex. The median [25 and 75, percentiles] stool wet weights were similar between the FAP (97.5 [69, 192] g.24 h-1) and the control (116 [61.5, 137] g.24 h-1) groups. Faecal cholesterol concentration was similar in the two groups (FAP = 2.3 [1.4, 4.2]; control = 3.5 [1.0, 6.0] mumol.g-1 dry wt) as was the concentration of total neutral sterols not including plant sterols (FAP = 17.2 [13.4, 21.0]; control = 18.2 [7.4, 21.6] mumol.g-1 dry wt). There were no significant differences in the proportions of cholesterol metabolised between the FAP (82.3 [74.2, 93.5]%) and control (72.1 [5.7, 81.3]%) groups. This study does not support the notion that faecal neutral sterol metabolism is uniquely different in patients with FAP.

Abstract
Alpha 1-antitrypsin was measured in 5-day faecal collections from patients with colorectal cancer or adenomatous polyps and a symptomatic control group. Collections were homogenized and lyophilized prior to measurement of alpha 1-antitrypsin by radial immuno-diffusion. Colorectal cancer dry weight concentrations were significantly higher than the symptomatic control results, with 57% having results greater than 95% normal values of this control group. There was no significant difference between adenomatous polyp dry weight concentrations and symptomatic control results. Wet weight concentrations were calculated from wet/dry ratios. Colorectal cancer wet weight concentrations were significantly higher than symptomatic control results with 48% having results greater than 95% normal values of this control group. Alpha 1-antitrypsin was also measured in non-lyophilized samples from an asymptomatic control group (n = 39). Colorectal cancer wet weight concentrations were significantly higher than asymptomatic control results, with 62% having results greater than 95% normal values of this control group. Faecal alpha 1-antitrypsin measurement deserves further assessment for use in detecting colorectal cancer.
