Abstract
PURPOSE The long-term prognosis of stapled and hand-sewn ileal pouch-anal anastomoses in familial adenomatous polyposis patients in Japan remains unknown. This study aimed to compare the overall survival in familial adenomatous polyposis patients who underwent stapled or hand-sewn ileal pouch-anal anastomosis. METHODS This multicenter retrospective study was conducted at 12 institutions in Shizuoka Prefecture, Japan. The clinical outcomes of 53 eligible familial adenomatous polyposis patients who underwent stapled (n = 24) and hand-sewn (n = 29) ileal pouch-anal anastomosis were compared. RESULTS The median follow-up duration was 171.5 months. The incidence of adenoma in the remnant rectum or anal transitional zone and metachronous rectal cancer was significantly more common in stapled ileal pouch-anal anastomosis (adenoma: stapled, 45.8%, vs. hand-sewn, 10.3%, p = 0.005; metachronous rectal cancer: 29.2%, vs. none, p = 0.002). The number of deaths was remarkably higher in stapled ileal pouch-anal anastomosis (p = 0.002). Metachronous rectal cancer was the most common cause of death. Overall survival was worse in stapled ileal pouch-anal anastomosis than in hand-sewn ileal pouch-anal anastomosis (120 months, 90.7% vs. 96.6%; 240 months, 63.7% vs. 96.6%; p = 0.044). Cox regression analysis revealed the independent effects of preoperative advanced colorectal cancer and stapled ileal pouch-anal anastomosis on overall survival. CONCLUSION Stapled ileal pouch-anal anastomosis negatively affected the overall survival of familial adenomatous polyposis patients. Therefore, hand-sewn ileal pouch-anal anastomosis is recommended for better prognosis in these patients.

Abstract
INTRODUCTION Restorative proctocolectomy results in the formation of a pouch that adapts to a more colonic phenotype. The incidence of cancer of the pouch is thought to be low with most societal guidelines differing on their recommendations for surveillance. AIMS We conducted a systematic review with meta-analysis to report the incidence of cancer in all pouch patients. METHODS The Embase, Embase classic and PubMed databases were searched between June 1979- June 2021. A random effects model was performed to find the pooled incidence of pouch cancer. In addition, we also looked for risk factors for pouch cancers. RESULTS Forty-six studies were included. In 19,964 patients with Ulcerative Colitis (UC) the pooled incidence of pouch cancer was 0.0030 (95% CI: 0.0016 -0.0055). In 3741 patients with Familial Adenomatous Polyposis (FAP) the pooled incidence of pouch cancer was 0.01 (95% CI: 0.01 - 0.02). In UC most pouch cancers were found to occur in the pouch body (0.59 (95% CI: 0.29-0.84)). CONCLUSIONS The findings suggest that the pooled incidence of pouch cancer in UC is similar to that which was previously published, and this is the first meta-analysis to report a pooled incidence for pouch cancer in FAP.

Cumulative incidence and risk factors for pouch adenomas associated with familial adenomatous polyposis following restorative proctocolectomy. World J Gastroenterol 2022; 28:4152-4162. [PMID: 36157110 PMCID: PMC9403429 DOI: 10.3748/wjg.v28.i30.4152] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/03/2022] [Revised: 04/24/2022] [Accepted: 07/17/2022] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND The emergence of restorative total proctocolectomy has significantly reduced the lifetime colorectal cancer risk associated with familial adenomatous polyposis (FAP). However, adenomas may develop in the ileal pouch over time and may even progress to carcinoma. We evaluated the cumulative incidence, time to development, and risk factors associated with ileal pouch adenoma.
AIM To evaluate the cumulative incidence, time to development, and risk factors associated with pouch adenoma.
METHODS In this retrospective, observational study conducted at a tertiary center, 95 patients with FAP who underwent restorative proctocolectomy at our center between 1989 and 2018 were consecutively included. The mean follow-up period was 88 mo.
RESULTS Pouch adenomas were found in 24 (25.3%) patients, with a median time of 52 mo to their first formation. Tubular adenomas were detected in most patients (95.9%). There were no high-grade dysplasia or malignancies. Of the 24 patients with pouch adenomas, 13 had all detected adenomas removed. Among the 13 patients who underwent complete adenoma removal, four (38.5%) developed recurrence. Among 11 (45.8%) patients with numerous polyps within the pouch, seven (63.6%) exhibited progression of pouch adenoma. The cumulative risks of pouch adenoma development at 5, 10, and 15 years after pouch surgery were 15.2%, 29.6%, and 44.1%, respectively. Severe colorectal polyposis (with more than 1000 polyps) was a significant risk factor for pouch adenoma development (hazard ratio, 2.49; 95% confidence interval: 1.04-5.96; P = 0.041).
CONCLUSION Pouch adenomas occur at a fairly high rate in association with FAP after restorative proctocolectomy, and a high colorectal polyp count is associated with pouch adenoma development.

Abstract
PURPOSE This study primarily aimed to compare the long-term prognosis of patients who underwent total colectomy/proctocolectomy with or without mucosectomy to the dentate line for the diagnosis of familial adenomatous polyposis (FAP). METHODS Patients who underwent total colectomy/proctocolectomy for FAP between January 1979 and December 2020 and were followed up at Hamamatsu University Hospital were included in this study. Those who underwent total proctocolectomy with hand-sewn ileal pouch-anal anastomosis were defined as the mucosectomy group. Those who underwent total colectomy or total proctocolectomy using the stapled ileal pouch-anal anastomosis approach were defined as the no mucosectomy group. RESULTS A total of 61 individuals (37 families) were diagnosed during the surveillance period (median, 191 months). Between the mucosectomy (n = 24) and no mucosectomy groups (n = 34), metachronous rectal cancer was significantly more common in the no mucosectomy group (21% in no mucosectomy vs. 0% in mucosectomy, P = 0.02). Overall survival in the no mucosectomy group was worse than that in the mucosectomy group (84.5% in no mucosectomy vs. 100% in mucosectomy at 120 months, 81.1% vs. 90.0% at 240 months, 50.6% vs. 75.0% at 360 months, P = 0.09). Cox regression analysis revealed an independent effect of not performing mucosectomy on overall survival (P = 0.03). CONCLUSION Long-term surveillance revealed that colectomy or total proctocolectomy without mucosectomy had a negative impact on the overall survival of patients with FAP. Therefore, we recommend total proctocolectomy with mucosectomy, i.e., hand-sewn ileal pouch-anal anastomosis, for FAP.

Abstract
Proctocolectomy with ileal pouch-anal anastomosis is the intervention of choice for ulcerative colitis and familial adenomatous polyposis requiring surgery. One of the long-term complications is pouch cancer, having a poor prognosis. The risk of high-grade dysplasia and cancer in the anal transitional zone and ileal pouch after 20 years is estimated to be 2 to 4.5% and 3 to 10% in ulcerative colitis and familial polyposis, respectively. The risk factors for ulcerative colitis are the presence of pre-operative dysplasia or cancer, disease duration > 10 years and severe villous atrophy. For familial polyposis, the risk factors are the number of pre-operative polyps > 1000, surgery with stapled anastomosis and the duration of follow-up. In the case of ulcerative colitis, a pouchoscopy should be performed annually if one of the following is present: dysplasia and cancer at surgery, primary sclerosing cholangitis, villous atrophy and active pouchitis (every 5 years without any of these factors). In the case of familial polyposis, endoscopy is recommended every year including chromoendoscopy. Even if anal transitional zone and ileal pouch cancers seldom occur following proctectomy for ulcerative colitis and familial adenomatous polyposis, the high mortality rate associated with this complication warrants endoscopic monitoring.

Abstract
BACKGROUND Rectal cuff and anal transitional zone neoplasia is an increasing challenge in patients with familial adenomatous polyposis who have undergone restorative proctocolectomy. Its real incidence, range of severity, and treatment efficacy are poorly documented. OBJECTIVE We sought to document the evolution of rectal cuff and anal transitional zone neoplasia and describe its management. DESIGN This is a retrospective cohort study collecting prospectively recorded data. SETTINGS This study involved a hereditary colorectal cancer group in a large academic medical center. PATIENTS All patients undergoing primary restorative proctocolectomy at this institution were included. INTERVENTIONS Surveillance pouchoscopy and treatment of rectal cuff/anal transitional zone neoplasia were performed. MAIN OUTCOME MEASURES The primary outcomes measured were the presence and the severity of rectal cuff/anal transitional zone neoplasia. Excision by cautery, snare, mucosectomy, or redo pouch was evaluated. RESULTS A total of 165 patients were included: 52% were male (86/165) with a median age at restorative proctocolectomy of 31.0 years (SD 12.8). In 117 of 165, the proctocolectomy was their first operation and, in 48 of 165, it followed a colectomy. Of the patients, 83% (137/165) had stapled anastomosis; 17% had mucosectomy with handsewn anastomosis; and 14% (23/165) were treated with sulindac at some point during their surveillance. Median follow-up was 10.1 years (interquartile range, 4.5-17.2) and the median number of pouchoscopies per patient was 4 (interquartile range, 2-8). Seventy-eight of 165 (47.3%) developed rectal cuff/anal transitional zone adenomas, more in the stapled group (52.3%; 72/137) than in the handsewn group (21.4%; 6/28; p < 0.005). Median time to adenoma was 4.5 years (interquartile range, 2.4-8.9). Three patients developed cancer under surveillance, and, in 3 other patients, cancers developed when screenings lapsed. Five patients developed symptomatic anal stenosis secondary to repeated surgeries (median, 9 procedures; range, 2-10). LIMITATIONS There was no quality-of-life measurement in patients who developed rectal cuff/anal transitional zone neoplasia. CONCLUSIONS Rectal cuff/anal transitional zone adenomas are more common than previously reported. Mild polyposis can be controlled endoscopically, but repeated procedures in a higher stage are associated with risk of anal stenosis. Compliance with surveillance is essential to avoid cancer.

INCIDENCIA Y TRATAMIENTO DE LA NEOPLASIA DEL REMANENTE RECTAL Y DE LA ZONA DE TRANSICIN ANAL EN PACIENTES CON POLIPOSIS ADENOMATOSA FAMILIAR ANTECEDENTES:La neoplasia del remanente rectal y de la zona de transición anal presenta un desafío mayor en pacientes con poliposis adenomatosa familiar tratados con una proctocolectomía restaurativa. Su incidencia real, el espectro de la gravedad y la eficacia del tratamiento están mal documentados.OBJETIVO:Buscamos documentar la evolución de la neoplasia del remanente rectal y de la zona de transición anal y describir su tratamiento.DISEÑO:Estudio de cohorte retrospectivo que recabó datos registrados prospectivamente.AMBITO:Un grupo con cáncer colorrectal hereditario de un importante centro médico académico.PACIENTES:Todos los pacientes operados por primera vez de proctocolectomía restaurativa en nuestra institución.INTERVENCIONES:Endoscopía del pouch para vigilancia y tratamiento de la neoplasia del remanente rectal / zona de transición anal.PRINCIPALES VARIABLES ANALIZADAS:La presencia y la gravedad de la neoplasia del remanente rectal / zona de transición anal. Resección con cauterio, asa, mucosectomía o rehacer el pouch.RESULTADOS:Se incluyeron un total de 165 pacientes: 52% eran hombres (86/165) con una mediana de edad al momento de la proctocolectomía restaurativa de 31,0 años (DE 12,8). En 117/165 la proctocolectomía fue su primera cirugía y en 48/165 fue posterior a una colectomía. En 83% (137/165) tenía una anastomosis con engrapadora, 17% tenía mucosectomía y anastomosis con sutura manual (HS). El 14% de los pacientes (23/165) fueron tratados con sulindac en algún momento durante su vigilancia. La mediana de seguimiento fue de 10,1 años (IQR: 4,5, 17,2) y la mediana del número de endoscopías del pouch por paciente fue de 4. (IQR: 2, 8) 78/165 (47,3%) desarrollaron adenomas en la zona de transición anal /remanente rectal, mayor en el grupo con engrapadaora (52,3%; 72/137) comparado con el grupo con sutura manual (21,4%; 6/28) (p <0,005). La mediana del tiempo hasta el adenoma fue de 4,5 años (IQR: 2,4, 8,9). Tres pacientes que se encontraban en vigilancia desarrollaron cáncer y en 3, otros cánceres se desarrollaron transcurrida la vigilancia. 5 pacientes desarrollaron estenosis anal sintomática secundaria a múltiples cirugías (mediana de 9 procedimientos; rango 2-10).LIMITACIONES:Falta de medición de la calidad de vida en pacientes que desarrollaron neoplasia del remanente rectal / zona de transición anal.CONCLUSIONES:Los adenomas de la zona de transición anal / remanente rectal son más comunes de lo reportado anteriormente. La poliposis leve se puede tratar por endoscopía, pero procedimientos repetidos en estadíos mayores se asocian con el riesgo de estenosis anal. El apego a la vigilancia es fundamental para evitar el cáncer. Consulte Video Resumen en http://links.lww.com/DCR/B594. (Traducción-Dr. Lisbeth Alarcon-Bernes).

Abstract
Heritable factors account for approximately 35% of colorectal cancer (CRC) risk, and almost 30% of the population in the UK have a family history of CRC. The quantification of an individual's lifetime risk of gastrointestinal cancer may incorporate clinical and molecular data, and depends on accurate phenotypic assessment and genetic diagnosis. In turn this may facilitate targeted risk-reducing interventions, including endoscopic surveillance, preventative surgery and chemoprophylaxis, which provide opportunities for cancer prevention. This guideline is an update from the 2010 British Society of Gastroenterology/Association of Coloproctology of Great Britain and Ireland (BSG/ACPGBI) guidelines for colorectal screening and surveillance in moderate and high-risk groups; however, this guideline is concerned specifically with people who have increased lifetime risk of CRC due to hereditary factors, including those with Lynch syndrome, polyposis or a family history of CRC. On this occasion we invited the UK Cancer Genetics Group (UKCGG), a subgroup within the British Society of Genetic Medicine (BSGM), as a partner to BSG and ACPGBI in the multidisciplinary guideline development process. We also invited external review through the Delphi process by members of the public as well as the steering committees of the European Hereditary Tumour Group (EHTG) and the European Society of Gastrointestinal Endoscopy (ESGE). A systematic review of 10 189 publications was undertaken to develop 67 evidence and expert opinion-based recommendations for the management of hereditary CRC risk. Ten research recommendations are also prioritised to inform clinical management of people at hereditary CRC risk.

Abstract
INTRODUCTION Restorative proctocolectomy and ileal pouch-anal reconstruction is the surgical standard for the majority of patients with familial adenomatous polyposis (FAP). The pouch-anal anastomosis may be performed handsewn after primary mucosectomy or by double stapling. Better functional results favour the latter; however, higher rates of remaining rectal mucosa with adenomas often necessitate secondary mucosectomy. Data on functional outcome after secondary mucosectomy is scarce. The aim of the study was to analyse whether patients who undergo secondary mucosectomy maintain their functional benefits compared to patients with primary mucosectomy. PATIENTS AND METHODS Twenty patients after secondary mucosectomy and 31 patients after primary mucosectomy were compared with respect to their functional outcome, using the MSKCC score, the Wexner score and ano-rectal physiology testing. RESULTS The MSKCC global score and the Wexner score showed a non-significant trend towards slightly better results after secondary mucosectomy (63.1 vs. 56.6, p = 0.0188 and 9.5 vs. 11, p = 0.3780). Patients after secondary mucosectomy also showed a tendency towards less bowel movements per 24 h (7 (range 4-11) vs. 8.5 (range 3-20), p = 0.1518). Resting pressures were slightly higher after secondary (44 vs. 39.6 mmHg, p = 0.4545) and squeeze pressures slightly higher after primary mucosectomy (87.6 vs. 81.2 mmHg, p = 0.6126). However, the results did not reach statistical significance. CONCLUSION The results of this study cannot ultimately resolve the controversy concerning handsewn versus stapled ileal pouch-anal anastomosis. Our results suggest a trend towards better functional results after stapled anastomosis with secondary mucosectomy.

Abstract
BACKGROUND There are different approaches for the surgical management of rectal-sparing familial adenomatous polyposis with variable impacts on both quality of life and survival. OBJECTIVE The aim of this study was to quantify the trade-offs between total proctocolectomy with IPAA versus total colectomy with ileorectal anastomosis using decision analysis. DESIGN We created a disease simulation Markov model to simulate the clinical events after IPAA and ileorectal anastomosis for rectal-sparing familial adenomatous polyposis in a cohort of individuals at the age 30 years. We used available literature to obtain different transition probabilities and health-states utilities. The output parameters were quality-adjusted life-years and life-years. Deterministic and probabilistic sensitivity analyses were performed. SETTINGS A decision analysis using a Markov model was conducted at a single center. PATIENTS Patients with rectal-sparing familial adenomatous polyposis at age 30 years were included. Rectal-sparing familial adenomatous polyposis is defined as the presence of 0 to 20 polyps that can be removed endoscopically. MAIN OUTCOME MEASURES Quality-adjusted life-years were measured. RESULTS Our model showed that the mean quality-adjusted life-years for IPAA was 25.12 and for ileorectal anastomosis was 27.12 in base-case analysis. Mean life-years for IPAA were 28.81 and 28.28 for ileorectal anastomosis. A 1-way sensitivity analysis was performed for all of the parameters in the model. None of the deterministic sensitivity analyses changed the model results across the range of plausible values. Probabilistic analysis identified that, in 86.9% of scenarios, ileorectal anastomosis had improved quality-adjusted life-years compared with IPAA. LIMITATIONS The study was limited by characteristics inherent to modeling studies. CONCLUSIONS Ileorectal anastomosis was found to be preferable for patients with rectal-sparing familial adenomatous polyposis when quality of life is taken into consideration. This model was robust based on both deterministic and probabilistic sensitivity analyses. These data should be taken into consideration when counseling patients regarding a surgical approach in rectal-sparing familial adenomatous polyposis.

Abstract
Duodenal cancer is a leading cause of death in patients with familial adenomatous polyposis (FAP). In patients with Spigelman's classification (SC) stage IV duodenal polyposis (DP), careful endoscopic surveillance by specialists or surgical intervention is mandatory. We herein report the surgical and pathological outcomes of FAP patients with SC stage duodenal polyposis undergoing pancreas-sparing total duodenectomy (PSTD), which has been rarely reported but seems optimal in such patients. PSTD and distal gastrectomy with Billroth-I type reconstruction in ten consecutive FAP patients with SC stage IV DP are reported. The median duration of surgery was 396 min (range 314-571 min) and the median estimated blood loss was 480 mL (range 100-975 mL). Significant postoperative complications included wound infection in 1 patient, pancreatic fistula [International Study Group on Pancreatic Fistula definition (ISGPF) grade B] in 4 patients. Histopathologic examinations revealed a well-differentiated carcinoma in situ in 3 patients and others were all adenomas. Over a median follow-up period of 15 months (range 9-29 months), 1 patient developed a stomal ulcer which improved with medical treatment. There were no patients with a body weight loss of ≥10 % relative to the preoperative body weight. No recurrence were experienced during the follow up period. Patients were free from postoperative diabetes mellitus. PSTD is a feasible and acceptable procedure in FAP patients with SC stage IV DP, in terms of surgical, pathological and clinical outcome. However, accumulation of the patients and long-term follow up study is necessary.

Abstract
Ileal pouch‐anal anastomosis (IPAA) after total proctocolectomy (TPC) can be conducted with either hand‐sewn or stapled anastomosis for patients with familial adenomatous polyposis (FAP). Although stapled IPAA without mucosectomy has a higher risk for developing adenomas in the remnant mucosa, it is the simpler procedure with potential benefit in short‐term outcomes. However, it remains controversial as to whether stapled IPAA has any advantages in reducing postoperative complications. The aim of the present study was to compare the postoperative complications and short‐term outcomes of stapled and hand‐sewn IPAA for patients with FAP, using a multicenter cohort sample in Japan. Data of 143 patients with FAP who underwent TPC with stapled IPAA (n=37) and hand‐sewn IPAA (n=106) at 23 institutions between 2000 and 2012 were collected. Postoperative complications, proportion of ostomy, fecal continence and overall survival were compared. Overall rates of the Clavien‐Dindo grade II‐IV complications were not different between the two groups (19% in stapled vs 25% in hand‐sewn, P=.42), with significantly fewer pouch‐related complications including leakage, pelvic abscess, vaginal fistula and anastomotic stricture in stapled IPAA (none in stapled vs 11% in hand‐sewn, P=.036). There was no mortality. Proportion of ostomy at 12 months was similar (2.7% in stapled vs 4.3% in hand‐sewn, P=.26). Mean Wexner score was similar. (0.47 in stapled vs 2.0 in hand‐sewn, P=.12). Five‐year overall survival excluding Stage IV patients was 96% in both groups. Stapled IPAA is a safe option in patients with FAP with a potential benefit in reducing pouch‐related complications.

Abstract
Germline mutations account for 5-10% of colorectal cancer. Most mutations are autosomal dominant with high penetrance and affected patients benefit greatly from appropriate treatment. This review presents the current knowledge regarding familial colorectal cancer and provides practical information based on international guidelines and the best available evidence regarding patient assessment, surveillance and surgical management. Surgeons are often the first point of contact and frequently, the main provider of care for families with cancer syndromes or patients with familial cancer. Patients with a polyposis phenotype should undergo appropriate genetic testing. In non-polyposis patients with a cancer diagnosis, tumor testing for Lynch syndrome can guide the use of genetic testing. In patients without a personal history of cancer or polyposis, a carefully obtained family history with testing of available tumor tissue or of a living relative affected by colorectal cancer informs the need for genetic testing. Surveillance and surgical management should be planned following thorough assessment of familial cancer risk. Evidence exists to provide guidance as to the surveillance strategies required, the specific indications of genetic testing and the appropriate timing of operative intervention. A carefully obtained family history with selective genetic testing should inform surveillance and surgical management in patients who have a genetic predisposition for the development of colorectal cancer.

Abstract
The majority of rectal carcinomas are sporadic in nature, and relevant testing for driver mutations to guide therapy is important. A thorough family history is necessary and helpful in elucidating a potential hereditary predilection for a patient's carcinoma. The adequate diagnosis of a heritable tendency toward colorectal carcinoma alters the management of a patient disease and permits the implementation of various surveillance algorithms as preventive measures.

Abstract
INTRODUCTION Restorative proctocolectomy has become the standard surgical procedure for familial adenomatous polyposis (FAP) patients. The use of stapler devices has initiated a controversial discussion concerning the ileal pouch-anal reconstruction. Some authors advocate a handsewn anastomosis after transanal mucosectomy. A double-stapled anastomosis leads to better functional results but seems to bear a higher risk of residual rectal mucosa with dysplasia and adenomas. The present study systematically analyses the rate of residual rectal mucosa after restorative proctocolectomy and handsewn vs. stapled anastomosis. PATIENTS AND METHODS One hundred FAP patients after restorative proctocolectomy undergoing regular follow-up at our outpatient clinic were included in the study. Proctoscopy with standardised biopsy sampling was performed. RESULTS Of the 100 patients, 50 had undergone a stapled and 50 a handsewn anastomosis. Median follow-up was 146.1 months (handsewn) vs. 44.8 months (stapled) (P < 0.0001). Eighty-seven patients received a proctoscopy with standardised biopsy sampling. Thirteen patients had been diagnosed with residual rectal mucosa before. Sixty-three patients (63 %) showed remaining rectal mucosa (42 (66.6 %) stapler, 21 (33.3 %) handsewn, P < 0.0001). Patients after stapled anastomosis had higher rates of circular rectal mucosa seams, while small mucosa islets predominated in the handsewn group. The rate of rectal adenomas was significantly higher in the stapler group (21 vs. 10, P = 0.02). CONCLUSION Rectal mucosa, especially wide mucosa seams, as well as rectal adenomas are found significantly more often after a stapled than after a handsewn anastomosis. As the follow-up interval in the stapler group was significantly shorter, the impact of these findings may still be underestimated.

Abstract
INTRODUCTION Australian Clinical Practice Guidelines suggest six to twelve-monthly endoscopic pouch surveillance in patients after restorative proctocolectomy for Familial Adenomatous Polyposis (FAP). There are several reports of adenomas and carcinomas forming within the ileum, ileal pouch mucosa or residual rectal mucosa. A retrospective clinical study was performed to audit pouch endoscopic surveillance at a large Sydney tertiary referral Hospital. The aim was to evaluate adenoma development after restorative proctocolectomy for FAP and the adherence rate to published clinical guidelines. METHODS Thirty-nine patients who had restorative proctocolectomy for FAP from 1985 to 2011 were identified. Demographic data, details of surgery, original histopathology and details of follow-up pouch endoscopy and pathology findings were obtained. RESULTS Of the thirty-nine patients, twenty-seven patients were included in this study. Adenomas were found in twelve of 27 (44%) patients. Mean time to first polyp formation was 88 months and median time was 72 months (range 18-249 months). All polyps were either tubular or tubulovillous in histology. One polyp had high grade dysplasia. The remainder had mild or moderate dysplasia. Polyps were excised either endo-anally or during pouchoscopy. None of the five patients who had a hand-sewn ileal pouch-anal anastomosis (IPAA) developed polyps on follow-up, compared with 12 of the 22 (55%) with a double stapled anastomosis (fishers exact test; p=0.047 (two-tailed)). Of those who developed pouch adenomas, eight (67%) developed further pouch adenomas on follow-up. CONCLUSIONS This study supports guidelines recommending lifelong pouch surveillance after restorative proctocolectomy for FAP. Those who develop pouch adenomas may be at greater risk of developing further adenomas. Residual rectal mucosa at the pouch-anal anastomosis should be carefully examined.

Abstract
BACKGROUND Polypoid lesions can develop in ileal pouches. The risk factors associated with the development of pouch polyps have not been studied. AIM To characterize clinical features, risk factors, and disease course of pouch polyp in a cohort of patients with underlying inflammatory bowel disease (IBD) from a subspecialty clinic. METHOD A total of 1094 patients with restorative proctocolectomy and IPAA for IBD presenting to our Pouchitis Clinic from 2002 to 2010 were included. Demographic, clinical, and endoscopic variables were analyzed. RESULTS The median durations from UC diagnosis to colectomy and from pouch creation to the last follow-up for the whole cohort were 6 (interquartile range [IQR]: 3-13) and 9years (IQR: 5-14), respectively. A total of 2472 surveillance and/or diagnostic pouchoscopies were performed for the cohort with a median follow-up of 5 (IQR: 2-6) years in the Pouchitis Clinic. The median number of pouchoscopies per patient was 2 (IQR: 1-3). Of the 1094 patients, 96 (8.8%) were found to have pouch polyps. The median size of the polyps was 1.2 (IQR: 1.0-2.0) cm. On histology, 93 patients (96.9%) had inflammatory-type polyps and 3 (3.1%) had polyps with low-grade dysplasia or indefinite for dysplasia. Multivariate logistic regression analysis demonstrated that chronic pouch inflammatory change was a risk factor for the development of pouch polyp with an odds ratio of 2.26 (95% confidence interval: 1.35-3.79; P=0.002). CONCLUSION The majority of pouch polyps in patients with underlying UC were benign. Patients with concomitant chronic pouch inflammatory changes had an increased risk for developing pouch polyps.

Abstract
AIM Restorative proctocolectomy with ileal pouch-anal anastomosis for patients with familial adenomatous polyposis (FAP) and ulcerative colitis (UC) has been modified from a transanal hand-suture after mucosectomy to a stapled ileal pouch-anal anastomosis (IPAA) without mucosectomy. Better functional results favour stapled anastomosis; however, stapled anastomosis results in higher rates of adenomas in persisting anorectal mucosa. The purpose of this study was to compare the two techniques of pouch-anal anastomosis with respect to early postoperative complications in a collective of FAP patients. METHOD The study was performed as a matched-pair analysis. Data were obtained from a prospectively collected database. RESULTS The overall rate of postoperative complications was higher after stapled IPAA (31% stapled vs 23% handsewn), with anastomotic stricture occurring in 24.3% (stapled) and 16.2% (handsewn) (P = 0.22). Any leakage or pelvic abscess formation after stapled anastomosis occurred within 30 days in almost all patients, whereas these were mainly diagnosed between 30 days and 6 months after handsewn IPAA. A laparoscopic approach was used in 56.7% of patients in the stapled group but in only two patients in the handsewn group. Intra-operative blood loss was significantly higher in the handsewn group (mean ± SD: 699 ± 511 ml vs 369 ± 343 ml; P < 0.0001), as was the volume of blood transfused (mean ± SD: 205 ± 365 ml vs 8 ± 49 ml; P < 0.0001). Function did not differ between the groups. CONCLUSION There was a nonstatistically significant tendency towards a higher rate of early postoperative complications after stapled IPAA.

Abstract
Restorative proctocolectomy is the most common surgical option for patients with familial adenomatous polyposis (FAP). However, adenomas may develop in the ileal pouch mucosa over time, and even carcinoma in the pouch has been reported. We therefore reviewed the prevalence, nature, and treatment of adenomas and carcinoma that develop after proctocolectomy in the ileal pouch mucosa in patients with FAP. In 25 reports that were reviewed, the incidence of adenomas in the ileal pouch varied from 6.7% to 73.9%. Several potential factors that favor the development of pouch polyposis have been investigated, but many remain controversial. Nevertheless, it seems certain that the age of the pouch is important. The risk appears to be 7% to 16% after 5 years, 35% to 42% after 10 years, and 75% after 15 years. On the other hand, only 21 cases of ileal pouch carcinoma have been recorded in the literature to date. The diagnosis of pouch carcinoma was made between 3 to 20 years (median, 10 years) after pouch construction. Although the risk of malignant transformation in ileal pouches is probably low, it is not negligible, and the long-term risk cannot presently be well quantified. Regular endoscopic surveillance, especially using chromoendoscopy, is recommended.

Abstract
INTRODUCTION Neoplastic change in ileal reservoirs after proctocolectomy has been reported in patients with familial adenomatous polyposis. We aim to determine the incidence and progression of neoplastic change in the ileal pouch of familial adenomatous polyposis patients at our institution. METHODS A retrospective review of all patients who underwent proctocolectomy for familial adenomatous polyposis with construction of an ileal pouch from 1972 to 2007 was performed. Data and status at follow-up were retrieved from the Mayo Clinic Colorectal Surgery Pouch database. RESULTS One hundred seventeen patients were identified with a median age of 26, 52 were male. Ileal reservoirs included J-pouch (a = 104), Kock pouch (n = 9), S-pouch (n = 3), and W-pouch (n = 1). Median follow-up was 125 months. Polyps were biopsied in 33 patients: non-dysplastic polyps (n = 2), low-grade dysplasia (n = 30), and adenocarcinoma (n = 1). No patients had high-grade dysplasia. Median time to development of dysplasia was 149 months. Adenocarcinoma developed in one patient after 284 months. Risk of dysplasia at 10, 20, and 25 years was 17, 45, and 69%, respectively. CONCLUSION Though there is a high incidence of low-grade dysplasia in the ileal reservoir in familial adenomatous polyposis patients, high-grade dysplasia and cancer occur rarely. Patients with low-grade dysplasia may still necessitate regular follow-up.

Abstract
BACKGROUND Restorative proctocolectomy and IPAA in patients with familial adenomatous polyposis may leave residual anal transitional zone mucosa that is prone to neoplasia. OBJECTIVE The aim of this study was to evaluate the long-term control of neoplasia at the IPAA, the functional outcomes, and the influence of anastomotic technique on these results. DESIGN : This research is a retrospective cohort study from a prospective database. SETTING The investigation took place in a high-volume specialized colorectal surgery department. PATIENTS Patients with familial adenomatous polyposis who underwent IPAA between 1983 and 2010 were included. MAIN OUTCOME MEASURES The primary outcomes measured were functional outcomes, quality of life, and the incidence of neoplasia in the anal transitional zone. RESULTS Eighty-six patients underwent mucosectomy and 174 underwent stapled anastomosis with mean 155 ± 99 and 95 ± 70 months follow-up. Eighteen patients (20.9%) in the mucosectomy group and 59 patients (33.9%) in the stapled group developed anal transitional zone adenomas (p = 0.03). One of 86 (1.2%) patients undergoing mucosectomy and 3 of 174 (1.7%) patients undergoing stapled anastomosis developed cancer in the anal transitional zone (p > 0.05). Three of these patients underwent an abdominoperineal resection, but one who refused abdominoperineal resection underwent transanal excision with neoileoanal anastomosis. Patients undergoing a mucosectomy had a significantly higher rate of anastomotic stricture, but other complications were similar. Incontinence, seepage, and pad usage were higher in the mucosectomy group. Cleveland global quality-of-life score was 0.8 ± 0.2 in patients with handsewn anastomoses and 0.8 ± 0.3 in patients with a stapled anastomoses (p > 0.05). LIMITATIONS This study was limited by its nonrandomized retrospective design. CONCLUSIONS Risk for the development of adenomas in the anal transitional zone is higher after a stapled IPAA than after a mucosectomy with handsewn anastomosis. However, control of anal transitional zone neoplasia results in a similar risk of cancer development. Because the stapled procedure is associated with better long-term functional outcomes than a mucosectomy, stapled IPAA is the preferable procedure for most patients with familial adenomatous polyposis.

Abstract
AIM The aim of the study was to evaluate intra-operative difficulties, complications and long-term bowel function in polyposis patients undergoing conversion of an ileorectal anastomosis to an ileoanal pouch, compared with patients with a primary ileoanal pouch operation. METHOD A national register-based retrospective study was performed with clinical follow-up and a questionnaire on long-term bowel function. RESULTS There were 84 patients in the study: 59 (70%) had a primary pouch operation and in 25 (30%) a secondary pouch procedure was attempted. This was abandoned, in one case, leaving 24 patients who had a successful secondary restorative proctocolectomy. The median (range) follow-up was 123 (0-359) months. There were no intra-operative difficulties in the 59 primary operations, but intra-operative difficulties were reported in nine of 25 secondary operations (P < 0.001). Complications within 1 month of surgery occurred in six of 59 primary operations and in none of 24 secondary operations (P < 0.001); and late surgical complications occurred in eight of 55 primary operations and in eight of 24 secondary operations (P = 0.13). The only difference in bowel function was a lower frequency of nocturnal defaecation after secondary pouch formation (P = 0.02). CONCLUSION Reoperation with proctectomy after a previous ileorectal anastomosis and conversion to restorative proctocolectomy is feasible in polyposis patients, with morbidity and functional results similar to those seen after a primary pouch operation.

Abstract
BACKGROUND There is controversy concerning whether or not to perform mucosectomy after IPAA in patients with familial adenomatous polyposis. Although more frequent adenoma formation at the anastomotic site in patients without a mucosectomy is documented, the interpretation of the theoretical reflections and empirical findings are ambiguous. OBJECTIVE The aim of this study was to assess the differences in adenoma formation at the anastomotic site and in the ileal pouch among patients with familial adenomatous polyposis after IPAA with or without mucosectomy. DESIGN Data were gathered from The Norwegian Polyposis Registry and The Cancer Registry of Norway. PATIENTS Sixty-one patients with familial adenomatous polyposis who had IPAA were included in the Norwegian Polyposis Registry. MAIN OUTCOME MEASURES The frequency of adenoma development in the pouch or at the anastomotic site was measured. RESULTS Thirty-nine patients had a pelvic pouch performed with mucosectomy and 22 patients without. The observational time was 15.5 and 13.7 years. Adenoma formation at the anastomotic site was 4 in 39 and 14 in 22, and the estimated rate was 17% vs 75% (p = 0.0001). One patient without mucosectomy had a cancer (Dukes A) at the anastomotic site. There was no estimated long-term difference in adenoma formation in the ileal pouches between the 2 surgical procedures (38%) (p = 0.10). LIMITATIONS The study is retrospective, in part, and relies on data from registries. There is a limited number of cases, and selection bias because of surgeon preference may exist. CONCLUSION In patients with familial adenomatous polyposis who undergo IPAA, adenoma formation at the anastomotic site is significantly reduced after mucosectomy. Mucosectomy may be the preferable procedure to prevent adenomas at the anastomotic site.

Abstract
The incidence of familial adenomatous polyposis (FAP) is one in 7,000 to 12,000 live births. Virtually, all surgically untreated patients with FAP inevitably develop colorectal-cancer in their lifetime because they carry the adenomatous polyposis coli gene. Thus prophylactic proctocolectomy is indicated. Surgical treatment of FAP is still controversial. There are however, four surgical options: ileorectal anastomosis, restorative proctocolectomy with ileal pouch-anal anastomosis, proctocolectomy with ileostomy, and proctocolectomy with continent-ileostomy. Conventional proctocolectomy options largely lie between colectomy with ileorectal anastomosis or ileal pouch-anal anastomosis. Detractors of ileal pouch-anal anastomosis prefer ileorectal anastomosis because of better functional results and quality of life. The functional outcome of total colectomy with ileorectal anastomosis is undoubtedly far superior to that of the ileoanal pouch; however, the risk for rectal cancer is increased by 30%. Even after mucosectomy, inadvertent small mucosal residual islands remain. These residual islands carry the potential for the development of subsequent malignancy. We reviewed the literature (1975-2012) on the incidence, nature, and possible etiology of subsequent ileal-pouch and anal transit zone adenocarcinoma after prophylactic surgery procedure for FAP. To date there are 24 studies reporting 92 pouch-related cancers; 15 case reports, 4 prospective and 5 retrospective studies. Twenty three of 92 cancers (25%) developed in the pouch mucosa and 69 (75%) in anal transit zone (ATZ). Current recommendation for pouch surveillance and treatment are presented. Data suggest lifetime surveillance of these patients.

Abstract
IPAA is a technically demanding procedure that requires appropriate skills and expertise. Adverse sequelae of IPAA are common. Accurate diagnosis and classification of pouch disorders and associated complications are important for proper management and prognosis. Based on presenting symptoms, appropriate and combined diagnostic modalities should apply. A multidisciplinary approach involving gastroenterologists, colorectal surgeons, gastrointestinal pathologists, and gastrointestinal radiologists is advocated for diagnosis and treatment of pouch disorders.

Abstract
BACKGROUND Restorative proctocolectomy and IPAA has become the treatment of choice in familial adenomatous polyposis. However, several cases of adenomas and carcinomas arising in the ileal pouch were reported. OBJECTIVE The aim of this study was to evaluate the prevalence and natural history of ileal pouch adenomas and the development of carcinomas in patients with restorative proctocolectomy for familial adenomatous polyposis. DESIGN AND SETTING We prospectively studied patients who underwent IPAA during the past 20 years at the surgical unit of the University of Florence in Italy. MAIN OUTCOME MEASURES We investigated the extent of the risk and the factors that are involved in the development of neoplastic changes of the pouch. Furthermore, because it is not entirely clear when and how polyps should be treated, we have revised our modality of treatment for this unusual pathology. PATIENTS Sixty-nine patients with familial adenomatous polyposis underwent restorative proctocolectomy. In 66 patients, handsewn ileoanal anastomosis with anal canal mucosectomy was performed. After surgery, all patients underwent endoscopic surveillance. RESULTS After 10 years of follow-up, 1 ileal pouch adenoma was found in 64.9% of restorative proctocolectomy patients, and ileal pouch carcinomas occurred in 2 patients (29 and 59 years old), 3 and 11 years after restorative proctocolectomy. The number of colonic adenomatous polyps influenced the occurrence of pouch adenomas. No patients with <200 colonic adenomas experienced pouch adenomas, but 46% of patients with >1000 colonic polyps had pouch adenomas, and 25% of patients with 200 to 1000 colonic polyps had pouch adenomas at follow-up. No relationship was found between ileal pouch adenomas and pouch shape (J, S, or straight ileoanal anastomosis with multiple myotomies) or the APC mutation. Polyps larger than 5 mm were removed by endoscopy or surgery. CONCLUSIONS Ileal pouch adenomas were common after restorative proctocolectomy. Patients >50 years of age and patients with >1000 colonic adenomas at the time of colectomy were more prone to ileal pouch adenomas. The development of malignancy in the terminal ileum can present a fast course and does not seem to follow the classic adenoma-carcinoma sequence.

Abstract
AIM In familial adenomatous polyposis, a restorative proctocolectomy with an ileo-anal pouch may be performed either with a mucosectomy and a hand-sewn anastomosis or as a stapled anastomosis without a mucosectomy. The disadvantage of the former is suboptimal bowel function and the disadvantage of the latter is a high risk of recurrent adenomas in the rectal mucosal remnant. METHOD A procedure is presented that combines the advantages of mucosectomy and stapled ileo-anal anastomosis. RESULTS No severe complications were seen in 14 patients. After a median follow up of 29 (range 7-144) months, 13 (93%) patients were fully continent day and night with a median frequency of defecation of 5 (range 2-8)/24 h. No adenomas were found at the annual endoscopic follow up. CONCLUSION Mucosectomy with a stapled ileo-anal pouch has few complications. Short-term results show good function and a very low risk of recurrent adenoma development.

Abstract
OBJECTIVE The study compared the risk of adenoma or carcinoma formation in the anorectal segment after either mucosectomy with manual anastomosis or stapled ileoanal anastomosis (IAA) following restorative proctocolectomy (RPC) for familial adenomatous polyposis (FAP). BACKGROUND Few data exist on the risk of adenoma formation after either technique in FAP. METHODS All endoscopy and histology reports for patients having RPC for FAP attending for annual pouchoscopy from 1978 to 2007 were reviewed. The incidence, timing, and histological characteristics of adenoma or carcinoma formation were recorded. RESULTS Of the 206 patients, 140 attended for endoscopic follow-up for a median of 10.3 years after RPC. Fifty-two patients developed neoplastic transformation in the anorectal segment, with a cumulative risk at 10 years of 22.6% after mucosectomy with manual anastomosis and 51.1% after stapled IAA (P < 0.001). The median time to first adenoma was longer after mucosectomy with handsewn anastomosis than after stapled IAA (10.1 vs 6.5 years, P < 0.001). On multivariate analysis, stapled IAA (hazard ratio= 3.45, 95% confidence interval = 1.01–4.98) and age at RPC older than 40 years (hazard ratio = 2.20, 95% confidence interval = 1.01–4.89) were significantly associated with increased risk of adenoma formation. Nine patients developed a large (>10 mm) adenoma. One patient (handsewn ileoanal anastomosis) developed adenocarcinoma in the anorectal mucosa at 13 years and required pouch excision. CONCLUSIONS Adenoma formation in the anorectal mucosa after RPC for FAP is common but carcinoma is rare. The risk is lower after mucosectomy with handsewn anastomosis than after stapled IAA. Regular endoscopic surveillance after either technique is mandatory.

Abstract
Abstract
Background
Colectomy and ileorectal anastomosis (IRA) or restorative proctocolectomy are performed for prophylaxis in familial adenomatous polyposis (FAP). After IRA patients may require secondary proctectomy for worsening polyposis or rectal cancer. Outcomes after IRA were evaluated and risk factors predictive of progressive rectal disease identified.
Methods
Parametric survival analysis was used to identify predictors of progressive rectal disease in all patients undergoing an IRA for FAP at a single centre. Hazard ratios (HRs) were calculated for phenotype, genotype, sex, age at surgery and presence of colonic cancer.
Results
Of 427 patients who underwent IRA, 48 (11·2 per cent) developed rectal cancer and 77 (18·0 per cent) required proctectomy for worsening polyposis over a median follow-up of 15 (range 7–25) years. By the age of 60 years half of the patients retained their rectum. Rectal polyp count exceeding 20 (HR 30·99, 95 per cent confidence interval 9·57 to 100·32; P < 0·001), APC mutation codon 1250–1450 (HR 3·91, 1·45 to 10·51; P = 0·007), colonic polyp count 500 or more (HR 2·18, 1·24 to 3·82; P = 0·006) and age less than 25 years at the time of surgery (HR 1·99, 1·17 to 3·37; P = 0·011) were independent predictors of progressive rectal disease.
Conclusion
The risk of proctectomy after IRA for FAP is based on patient genotype, phenotype and age at surgery.

Abstract
Colorectal cancer is one of the major causes of cancer deaths in both men and women. It is estimated that 5 to 10% of patients with colorectal cancer have an inherited germline mutation that predisposes them to cancer. Hereditary colorectal cancer syndromes can be divided into those associated with colonic polyposis - familial adenomatous polyposis (FAP), attenuated familial adenomatous polyposis (aFAP), and MYH associated polyposis (MAP), and those not associated with colonic polyposis - hereditary nonpolyposis colon cancer (HNPCC). The hereditary polyposes are usually easier to diagnose than HNPCC, but their higher penetrance and variable phenotype pose some difficult problems in management and surveillance. The timing and type of surgical intervention, the management of desmoid risk, the treatment of rectal or pouch neoplasia, and the management of duodenal neoplasia are all questions that must be addressed in patients with FAP or MAP.

Abstract
Restorative proctocolectomy (RPC) with ileal pouch-anal anastomosis is the surgical procedure of choice for patients with ulcerative colitis (UC). It is also performed in selected patients with familial adenomatous polyposis (FAP). A significant proportion of patients will develop pouch dysfunction. Flexible pouchoscopy is the most important initial investigation in patients with dysfunction. It is also important in UC and FAP surveillance. The aim is to provide gastroenterologists with a clear understanding of the technique, indications, and diagnostic pitfalls when investigating RPC patients with flexible pouchoscopy. Flexible pouchoscopy for the investigation of RPC patients with pouch dysfunction has a high diagnostic yield, with most causes of pouch dysfunction identifiable during this procedure. The risk of developing dysplasia following RPC is low. Surveillance pouchoscopy is only recommended in those with FAP, those with a previous history of dysplasia or carcinoma, primary sclerosing cholangitis, those with a retained rectal cuff, and those with Type C histological changes. Flexible pouchoscopy is a useful first-line investigation in patients with pouch dysfunction. It can be performed without sedation and has a high diagnostic yield; it is also important as part of surveillance in FAP and selected UC patients.

AIMS To assess the suitability of confocal laser endomicroscopy for the in vivo diagnosis of mucosal changes in ileal pouch for ulcerative colitis and familial adenomatous polyposis. METHODS Standard endoscopy and endomicroscopy were performed in 18 pouches. Confocal images were scored for the presence of villous atrophy, inflammation, ulceration, colonic metaplasia and dysplasia. Targeted biopsies were taken. Endomicroscopic and histological findings were compared. RESULTS At standard endoscopy, the signs of pouchitis were recorded in 7/18 (38.9%) patients. At endomicroscopy, pathological features were found in 16/18 (88.9%), villous atrophy in 15/18 (83.3%), inflammation in 13/18 (72.2%), ulceration in 3/18 (16.7%), and colonic metaplasia in 12/18 (67.7%). No dysplasia was observed. At histology, abnormalities were present in 17/18 (94.4%): villous atrophy in 15/18 (83.3%), inflammation in 17/18 (94.4%), ulceration in 6/18 (33.3%), colonic metaplasia in 15/18 (83.3%). Morphological changes of the ileal pouch could be predicted with an accuracy of 94.4% (95% CI: 74.2-99.0). The k-value for intra- and interobserver agreement was 0.93 and 0.78, respectively. CONCLUSIONS Endomicroscopy may be helpful in the evaluation of morphologic changes in ileal pouch. The small size of the population sample requires further studies for the results to be confirmed.

Abstract
BACKGROUND & AIMS At present, more than half of patients with familial adenomatous polyposis (FAP) are treated with a proctocolectomy and an ileal pouch-anal anastomosis (IPAA). Originally it was thought that this procedure would eliminate the risk of developing rectal cancer. However, an increasing number of studies reported development of adenoma and carcinoma in the pouch. The aim of this study was to evaluate the long-term risk of developing adenomas and carcinomas in the pouch in a large cohort of Dutch FAP patients. METHODS A total of 254 patients with FAP who underwent an IPAA were selected from the Dutch Polyposis Registry. The results of the surveillance examinations and the pathology reports were analyzed. Surveillance with chromoendoscopy was offered to a subgroup of patients. RESULTS Full information on follow-up was available in 212 (84%) patients. These patients (56% male) underwent a total of 761 endoscopies. The mean follow-up was 7.9 years (range, 0.4-20.3 years). The cumulative risk of developing an adenoma in the pouch at 10-year follow-up was 45%. Twenty-five patients (11.8%) developed an adenoma with advanced pathology, and 4 (1.9%) developed a carcinoma. The cumulative risk of developing a pouch carcinoma at 10-year follow-up was 1%. A very high prevalence (75.7%) of adenomas was found in a subgroup of patients who were examined with chromoendoscopy. CONCLUSIONS This study demonstrated that although the risk of developing adenomas in the pouch after an IPAA is high, the risk of malignant degeneration appears to be low. The use of chromoendoscopy improves the detection of small adenomas.

Abstract
OBJECTIVE One surgical option to treat failure after restorative proctocolectomy (RPC) is indefinite diversion (ID) without excision of the pouch. The study aimed to assess the mucosal morphology of the pouch and ileoanal anastomosis (IAA) over time after ID with particular reference to inflammation, dysplasia and carcinoma. METHOD Patients with ID were identified from the hospital's Ileal Pouch Database. Individuals were invited by mail to attend for flexible pouchoscopy and biopsy from the ileal pouch and immediately distal to the IAA. RESULTS Of 1822 patients on the database, 28 had undergone ID. Of these, 20 patients (18 ulcerative colitis, one familial adenomatous polyposis, one pseudo-obstruction) of median age 42 (18-67) years took part. There were eight males. The median (range) intervals from diagnosis of primary disease, pouch surgery and ID to the time of study were 221 (63-410), 146 (31-314) and 44 (10-159) months respectively. One patient had dysplasia in the original resection specimen. Five patients developed type C changes in the pouch. Of these three were identified between RPC and ID, one developed between ID and the present assessment and one was identified for the first time at the present assessment. No case of dysplasia or cancer was found in any of the biopsies. Rectal mucosa was found in biopsies from the IAA in four patients (three stapled; one handsewn); this was inflamed in three patients. CONCLUSION At a median follow-up of 12 years after RPC and 3.6 years after indefinite diversion no instance of dysplasia or carcinoma in the ileal reservoir or distal to the IAA was found in any of the 20 patients having ID. Type C changes occurred at some time in five (25%) patients, indicating the importance of continued follow up.

Abstract
BACKGROUND Restorative proctocolectomy with ileal pouch-anal anastomosis is the procedure of choice for the majority of patients with ulcerative colitis who require surgery. Over 2500 patients in the UK have undergone restorative proctocolectomy. It is now increasingly being performed in district general hospitals as well as in specialist inflammatory bowel disease units. Gastroenterologists are increasingly involved in the management of patients following restorative proctocolectomy. AIM To provide gastroenterologists with a clear understanding of the investigation and evidence-based management of complications and the aftercare required in patients who have undergone restorative proctocolectomy. RESULTS Following restorative proctocolectomy, most patients have an excellent long-term functional outcome. Pouchitis, pelvic sepsis and poor function are the most common causes of failure. The development of cancer is rare; nevertheless, long-term follow-up is required. CONCLUSIONS The investigation and management of patients who develop complications require a multidisciplinary team approach to optimize the outcome. Protocols are suggested for investigation and management of patients with complications and for long-term cancer surveillance.

Abstract
BACKGROUND It is reported that previous colectomy and ileorectal anastomosis (IRA) has no effect on postoperative complications and functional outcomes of secondary proctectomy and ileal pouch-anal anastomosis (IPAA) in patients with familial adenomatous polyposis (FAP). This retrospective study re-examined the question in a single centre. METHODS Some 185 patients were grouped by either IPAA as the initial prophylactic surgical procedure (primary IPAA) or IPAA preceded by IRA (secondary IPAA). Data on functional outcomes were available for 104, 83 and 56 patients at years 1, 5 and 10 respectively. RESULTS The 78 patients who had secondary IPAA were older at the time of operation than the 107 who underwent primary IPAA (35.7 versus 29.2 years; P < 0.001). Six (8 per cent) of the secondary IPAA procedures could not be completed. Otherwise, apart from more wound infections in the secondary IPAA group (9 versus 0.9 per cent in the primary IPAA group; P = 0.012), there were no significant differences in rates of complications, functional outcomes, desmoid disease or pouch failure. CONCLUSION Conversion from IRA to IPAA may not be possible in patients with FAP. Where conversion is successful, pouch outcomes are similar but wound infections are more frequent.

Abstract
Both medical and surgical therapies for ulcerative colitis have inherent advantages and disadvantages that must be balanced for patients with moderate to severe disease. Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical treatment of choice for the majority of patients with ulcerative colitis who require proctocolectomy. However, adverse sequelae of mechanical, inflammatory, functional, neoplastic, and metabolic conditions related to the pouch can occur postoperatively. Recognition and familiarization of the disease conditions related to the ileal pouch can be challenging for practicing gastroenterologists. Accurate diagnosis and classification of the disease conditions are imperative for proper management and prognosis.

Abstract
PURPOSE Children with familial adenomatous polyposis have a greater mortality and morbidity in the first decade of life compared with the general population. Some children with a more severe disease phenotype present early with colorectal adenomata and may require colectomy at an early age. We present our multidisciplinary clinic experience with familial adenomatous polyposis in children younger than age ten years at the time of presentation. METHODS A cross-sectional analysis was performed on all patients with suspected or confirmed familial adenomatous polyposis presenting in the first decade of life and followed by the multidisciplinary Pediatric Hereditary Polyposis Clinic at our institutions. Analysis included demographics, clinical presentation and course, gene mutation testing, endoscopic-histologic findings, and surgical outcome. RESULTS Twenty-two children (11 males) presented with suspected or confirmed familial adenomatous polyposis. Two were discharged from follow-up after negative adenomatous polyposis coli gene mutation testing. The rest underwent annual hepatoblastoma surveillance through age ten years with negative findings. Twelve patients presented with symptoms: six had de novo familial adenomatous polyposis. Seven had gastrointestinal hemorrhage and went on to colonoscopy. Four patients with adenomatous polyposis coli gene mutation at codon 1309 were referred for colectomy before age ten years. Referral to colectomy was earlier in patients with 1309 mutation and with de novo familial adenomatous polyposis. CONCLUSIONS Children with familial adenomatous polyposis younger than age ten years may present presymptomatically for disease surveillance. Familial adenomatous polyposis with adenomatous polyposis coli gene mutation at codon 1309 entails a risk of a more aggressive phenotype; early colectomy may be indicated in children harboring this gene mutation.

Abstract
Here we give an overview of colorectal cancer screening strategies with an emphasis on the diagnosis and management of rectal cancer. We review the published studies on screening in the high-risk population, including patients with a history of colorectal cancer, inflammatory bowel disease and inherited conditions. In the average-risk population, the evidence base for a number of screening strategies is evaluated, including endoscopy, contrast studies and faecal occult blood testing. Screening guidelines in the high-risk population are predominantly based on case-control studies comparing the incidence of colorectal cancer in screened and control groups. Screening the average-risk population for colorectal cancer reduces cancer-specific mortality by 15% after biennial guaiac faecal occult blood testing and 50-80% after flexible sigmoidoscopy. All of the screening strategies outlined have a greater sensitivity for distal lesions than proximal lesions.

Abstract
PURPOSE Restorative proctocolectomy with a double-stapled pouch-anal anastomosis retains a cuff of diseased columnar mucosa (columnar cuff) in the upper anal canal that may require biopsy. Biopsying this can be difficult and colonic phenotypic change in the pouch can lead to errors interpreting the histology. This study was designed to investigate the use of a monoclonal antibody to sucrase-isomaltase for differentiating ileal pouch from columnar cuff mucosa. Then, by using this antibody, the ability to accurately take and report biopsies from the anal canal was examined. METHODS The technique of staining for sucrase-isomaltase was developed. From 113 patients who had a double-stapled pouch-anal anastomosis, 467 formalin-fixed biopsies and 177 fresh-frozen biopsies were taken from the ileal pouch, columnar cuff, or anal transitional zone. Biopsies were stained with a monoclonal antibody to sucrase-isomaltase, and fixed biopsies were routinely reported after staining with hematoxylin and eosin. RESULTS A monoclonal antibody to sucrase-isomaltase reliably discriminated between ileal from rectal mucosa. A biopsy of columnar cuff mucosa as reported by routine histology was obtained during 72 percent of attempted outpatient examinations. Sucrase-isomaltase staining of reported columnar cuff biopsies showed that biopsies were of pouch rather than columnar cuff in 4.4 percent (95 percent confidence interval, 2-8) of outpatient examinations. CONCLUSIONS The monoclonal antibody to sucrase-isomaltase used in this study may have a clinical role when interpreting columnar cuff biopsies from patients being investigated for pouch dysfunction, or in patients having surveillance biopsies to exclude neoplasia in the columnar cuff.
