Incidence and Risk Factors of Cancer in the Anal Transitional Zone and Ileal Pouch following Surgery for Ulcerative Colitis and Familial Adenomatous Polyposis.

[PMID: 35158797 PMCID: PMC8833833 DOI: 10.3390/cancers14030530] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2021] [Revised: 01/17/2022] [Accepted: 01/18/2022] [Indexed: 12/29/2022] Open
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
Pouchitis is a common complication in ulcerative colitis patients after total proctocolectomy. This is an unspecific inflammation of the ileo-anal pouch, the aetiology of which is not fully known. This inflammation induces the onset of symptoms such as urgency, diarrhoea, rectal bleeding and abdominal pain. Many patients suffering from pouchitis have a lower quality of life. In addition to symptoms, an endoscopy with biopsies is mandatory in order to establish a definite diagnosis. The recommended index to assess its activity is the Pouchitis Disease Activity Index (PDAI), but its modified version (PDAIm) can be used in clinical practice. In accordance with the duration of symptoms, pouchitis can be classified as acute (<4 weeks) or chronic (>4 weeks), and, regarding its course, pouchitis can be infrequent (<4 episodes per year), recurrent (>4 episodes per year) or continuous.

Abstract
Quality of life after ileal pouch-anal anastomosis (IPAA) surgery is generally good. However, patients can be troubled by pouch-related symptoms and pouch disorders that can be inflammatory, mechanical/surgical, and functional. Management of patients with IPAA begins with measures to maintain a healthy pouch such as optimizing pouch function, providing tailored advice on a healthy diet and lifestyle, screening for and addressing metabolic complications of IPAA, pouch surveillance, and risk stratification for risk of pouchitis and pouch failure. Pouchitis is the most common inflammatory disorder. Primary pouchitis is a spectrum currently classified into three progressive phases-an antibiotic-responsive, an antibiotic-dependent, and an antibiotic-refractory phase. It is predominately microbially mediated in acute antibiotic-responsive pouchitis and predominately immune mediated in chronic antibiotic-refractory pouchitis (CARP). Secondary prophylaxis is recommended for recurrent antibiotic-responsive and for antibiotic-dependent pouchitis. Secondary causes of antibiotic-refractory pouchitis should be ruled out before a diagnosis of CARP is made. CARP is best classified as primary sclerosing cholangitis associated, immunoglobulin G4-associated, and autoimmune. Primary sclerosing cholangitis-associated CARP can be treated with budesonide or oral vancomycin. Early recognition of immunoglobulin G4-associated pouchitis minimizes ineffective antibiotic use. Autoimmune CARP can be managed in a manner similar to UC. The current place of immunosuppressives in the treatment algorithm depends on availability and early access to biological agents. Vedolizumab and ustekinumab are the preferred first- and second-line biologics for autoimmune CARP owing to their efficacy, better side effect profile, and low immunogenicity and need for concomitant immunomodulatory therapy. Antitumor necrosis factor should be reserved for autoimmune CARP failing the above and for CD of the pouch. There are no guidelines for the surveillance of pouches for dysplasia. Incidence varies based on a patient's risk. Since incidence is low, a risk-stratified approach is recommended.

Abstract
The accepted current standard for treatment of medically refractory ulcerative colitis is total proctocolectomy with an ileal pouch-anal anastomosis for restoration of continence. There are 2 techniques by which the anastomosis can be performed, including handsewn and stapled. Handsewn anastomosis with mucosectomy was the first method described; however, it has been associated with significant incontinence. The double-stapled anastomosis was developed in response to improve postoperative function. Controversy remains as to which technique is superior as both have disadvantages. This review article addresses differences between the 2 methodologies in relation to postoperative complications, anorectal physiology, functional outcomes, and oncological safety.

Abstract
Objective: There is no consensus on whether, when and how to surveil an ileal pouch. The aims of this study were to evaluate experts’ opinions and practice patterns on pouch surveillance and to determine if they were associated with detection of neoplasia. Methods: Eligible physicians were identified by searching the literature in MEDLINE and the physician list of the Crohn’s and Colitis Foundation of America and surveying by questionnaire. Results: Fifty-two eligible participants from 32 tertiary institutions were identified. Forty-one physicians (79%) felt that surveillance pouchoscopy was necessary, and 36 (69%) believed that pouchoscopy with biopsy was effective for the detection of neoplasia. Great variation exists with regard to the frequency of surveillance pouchoscopy. Eighteen physicians (35%) reported the detection of a total of 4 pouch dysplasias and 15 pouch cancers within the previous 5 years. The follow-up number of ileal pouches per year was significantly higher in the neoplasia detection group (50 vs 25, P = 0.041). Those who reported detecting neoplasia took even fewer biopsies from the ileal pouch body during the pouchoscopy examination (>3 biopsies per location, 44% vs 82%, P = 0.005). Multivariable analysis showed that the number of patients with ileal pouches followed up per year was the only independent factor associated with the detection of pouch neoplasia (odds ratio [OR]: 1.5; 95% confidence interval [CI]: 1.1–2.1; P = 0.005). Conclusion: Most experts agree with performing pouchoscopy and biopsy for surveillance of ileal pouch neoplasia, although the optimal interval varies greatly. The detection of pouch neoplasia appears to be related to patient volume and physician experience.

Abstract
PURPOSE Cancers developing near the site of the ileoanal pouch anastomosis (IPAA) have been reported, but uncommonly in the ileal pouch mucosa itself. We present a recently encountered case of ileal pouch cancer and review the literature to examine the prevalence, risk factors, and natural history of ileal pouch adenocarcinoma as well as pouch surveillance. METHODS A chart review of the case from our institution was conducted, and a PubMed search was undertaken for articles describing adenocarcinoma arising from the ileal pouch mucosa. RESULTS Twenty articles containing 26 cases were reviewed in addition to our described case. More than half were reported in the last decade. Only three cases were definitively stage 1. All seven patients who underwent regular surveillance were diagnosed with stage 1 or 2 disease. Seventeen patients had neoplasia in their original proctocolectomy specimen and six did not. The mean time from pouch creation to adenocarcinoma was 8.9 years. CONCLUSIONS The risk of developing ileal pouch mucosa adenocarcinoma appears low. However, increasing reports of these cancers are concerning as most patients present with advanced disease after many years. Patients with a previous history of dysplasia/cancer may be at increased risk. We believe surveillance after IPAA should include the anal transition zone and the ileal pouch mucosa. The establishment of expert consensus guidelines on pouch surveillance should be considered in the near future.

Abstract
BACKGROUND There is no consensus on the need for and the interval of surveillance pouchoscopy in asymptomatic ileal pouch patients with underlying ulcerative colitis (UC). The purpose of this study was to evaluate the likelihood of finding dysplasia or incidental ileal pouch disorders in asymptomatic patients undergoing surveillance pouchoscopy. METHODS This study included all eligible consecutive asymptomatic UC patients undergoing surveillance pouchoscopy to our subspecialty Pouchitis Clinic from 2002 to 2011. Univariable and multivariable analyses were performed. RESULTS A total of 138 patients met the inclusion criteria, with 72 (52.2 %) being male. The mean age at pouch construction was 45.4 ± 15.0 years, and the mean interval from ileostomy closure to the inception of first surveillance pouchoscopy was 89.4 ± 78.8 months. One patient was found to have indefinite for dysplasia on pouch body mucosal biopsy (0.7 %), and two patients had non-caseating granulomas, suggesting Crohn's disease (CD) of the pouch. Of the 138 patients, 69 (50 %) had abnormal endoscopic findings, 102 (73.9 %) had acute and/or chronic inflammation on histology, and 62 (44.9 %) had both abnormal endoscopy and histology. The abnormal endoscopic findings included isolated pouch ulcer (n = 29, 21 %), active pouchitis (n = 31, 22.5 %), inflammatory polyps (n = 10, 7.2 %), strictures at the anastomosis (n = 5, 3.6 %), inlet (n = 10, 7.2 %) or outlet (n = 2, 1.4 %). Thirteen patients (13/17, 76.5 %) with pouch strictures underwent endoscopic balloon dilatation therapy and nine had (9/10, 90 %) endoscopic polypectomy. Multivariable analysis showed that patients with a preoperative diagnosis of CD and concomitant extraintestinal manifestations had a higher risk for abnormal pouch endoscopic findings with odds ratios of 2.552 (95 % confidence interval [CI] 1.108-16.545, p = 0.035) and 4.281 (95 % CI 1.204-5.409, p = 0.014), respectively. CONCLUSIONS Dysplasia was rare in asymptomatic patients with restorative proctocolectomy who underwent surveillance pouchoscopy in this cross-sectional study. However, "incidental" abnormal endoscopic and/or histologic findings were common, which often needed endoscopic therapeutic intervention.

Abstract
OBJECTIVE Many changes in mucosal morphology are observed following ileal pouch construction, including colonic metaplasia and dysplasia. Additionally, one rare but potential complication is the development of adenocarcinoma of the reservoir. The aim of this study was to evaluate the most frequently observed histopathological changes in ileal pouches and to correlate these changes with potential risk factors for complications. METHODS A total of 41 patients were enrolled in the study and divided into the following three groups: a non-pouchitis group (group 1) (n = 20; 8 males; mean age: 47.5 years) demonstrating optimal outcome; a pouchitis without antibiotics group (group 2) (n = 14; 4 males; mean age: 47 years), containing individuals with pouchitis who did not receive treatment with antibiotics; and a pouchitis plus antibiotics group (group 3) (n = 7; 3 males; mean age: 41 years), containing those patients with pouchitis who were administered antibiotics. Ileal pouch endoscopy was performed, and tissue biopsy samples were collected for histopathological analysis. RESULTS Colonic metaplasia was found in 15 (36.6%) of the 41 patients evaluated; of these, five (25%) were from group 1, eight (57.1%) were from group 2, and two (28.6%) were from group 3. However, no correlation was established between the presence of metaplasia and pouchitis (p = 0.17). and no differences in mucosal atrophy or the degree of chronic or acute inflammation were observed between groups 1, 2, and 3 (p>0.45). Moreover, no dysplasia or neoplastic changes were detected. However, the degree of mucosal atrophy correlated well with the time of postoperative follow-up (p = 0.05). CONCLUSIONS The degree of mucosal atrophy, the presence of colonic metaplasia, and the degree of acute or chronic inflammation do not appear to constitute risk factors for the development of pouchitis. Moreover, we observed that longer postoperative follow-up times were associated with greater degrees of mucosal atrophy.

Abstract
AIM Dysplasia of the pouch mucosa after restorative proctocolectomy is rare. The aim of this study was to establish whether there is a correlation between pouchitis and dysplasia. METHOD A group of 276 patients treated for ulcerative colitis by restorative proctocolectomy between 1984 and 2009 was analysed. The presence or absence of pouchitis and dysplasia within the pouch was evaluated. RESULTS Inflammation was diagnosed in 66 (23.9%) patients, low-grade dysplasia in five (1.8%), high-grade dysplasia in three (1.1%), and cancer in one patient (0.4%). The prevalence of low-grade dysplasia was significantly higher in patients with inflammation than in those without (P < 0.04). High-grade dysplasia was significantly more frequent in pouchitis than in non-inflamed pouches (P < 0.01). Logistic regression analysis suggested that the occurrence of mucosal inflammation increased the risk of low grade dysplasia. CONCLUSION Patients with chronic pouchitis are at risk of dysplasia and require surveillance of the pouch.

Abstract
UNLABELLED Restorative proctocolectomy is considered a surgical treatment of choice in ulcerative colitis (UC) and familial adenomatous polyposis (FAP).The aim of the study was to evaluate postoperative complications in patients who underwent surgery for familial adenomatous polyposis and ulcerative colitis, on the basis of a retrospective data analysis. MATERIAL AND METHODS Data of 138 patients after restorative proctocolectomy performed between 1985 and 2008 were collected at routine follow-up visits in 2004-2008. We evaluated the presence of pouchitis, the degree of ileal pouch mucosa atrophy, the presence of ileal pouch mucosal metaplasia, the presence of ileal pouch malignancies, the necessity for diverting ileostomy, the necessity for pouch resection, and severe faecal incontinence. RESULTS Complications were observed in 45 (32.4%) patients. Thirty-seven patients developed pouchitis (26.6%). Low-degree dysplasia, severe dysplasia or malignancies were observed in total in 20 patients (14.4%). Six (4.3%) operated patients developed other analysed complications. CONCLUSIONS The most common complications of restorative proctocolectomy were dysplasia and pouchitis. The most common complication in patients operated for UC was pouchitis. The low observed incidence of intestinal pouchitis may be attributed to the implemented prophylaxis of inflammation. Dysplasia was the most common complication in patients undergoing proctocolectomy for FAP. Due to an increased risk of dysplastic lesions as compared with UC patients, careful endoscopic follow-up examinations are obligatory in this patient group. Other analysed complications were uncommon and were mostly a consequence of chronic pouchitis. Clinical symptoms of pouch-related problems were similar in both analysed groups.

Abstract
Objective. Study the functional results and mucosal changes in the ileal pouch after restorative proctocolectomy with J-reservoir for ulcerative colitis. Material and Methods. Followup study of 125 patients with J-reservoir with one disease-specific- and one general (SF-36) quality of life-questionnaire, rectoscopy with biopsies, and stool samples to evaluate inflammation, dysplasia, presence of Helicobacter pylori and calprotectin level. Results. Fourteen J-reservoirs were removed or deactivated, leaving 111 patients for followup. The followup time was 6.8 (1-15) years. 87.4% of the patients were satisfied. 93.1% had some kind of functional restriction: food- (75.5%), social- (28.9%), physical- (37%) or sexual restriction (15.3%). 18.6% had often or sometimes faecal incontinence. Low daytime faecal frequency was associated with good quality of life. 13 patients (12.6%) had a less favourable result. There was no pouch-dysplasia. Calprotectin levels were increased in patients with visible pouch inflammation or history of pouchitis. HP was diagnosed by RUT in 42.3%, but was not associated with inflammation or pouchitis. Conclusions. Most patients were satisfied with the J-reservoir in spite of a high frequency of various restrictions. 12.6% (13 patients) had a less favourable functional result, partly due to a high frequency of defecations, pain, pouchitis and inflammation.

Abstract
BACKGROUND Colorectal cancer (CRC), the most lethal long-term complication of inflammatory bowel disease (IBD), is the culmination of a complex sequence of molecular and histologic derangements of the colon epithelium that are initiated and at least partially sustained by prolonged chronic inflammation. Dysplasia, the earliest histologic manifestation of this process, plays an important role in cancer prevention by providing the first clinical alert that this sequence is under way and by serving as an endpoint in colonoscopic surveillance of patients at high risk for CRC. Restorative proctocolectomy (RPC) is indicated for patients with IBD, specifically for ulcerative colitis that is refractory to medical treatment, emergency conditions, and/or in case of neoplastic transformation. Even after RPC with mucosectomy, pouch-related carcinomas have recently been reported with increasing frequency since the first report in 1984. We review IBD-associated CRC and pouch-related neoplasia prevalence, adverse events, risk factors, and surveillances. METHODS Literature of IBD-associated CRC patients and those undergoing RPC surgeries through 2010 were prospectively reviewed. RESULTS We found 12 studies from retrospective series and 15 case reports. To date, there are 43 reported cases of pouch-related cancers. Thirty-two patients had cancer in the anal transit zone (ATZ); of these, 28 patients had mucosectomy. Eleven patients had cancer found in the pouch body. CONCLUSION RPC with mucosectomy does not necessarily eliminate risks. There is little evidence to support routine surveillance of pouch mucosa and the ATZ except for patients associated with histological type C changes, sclerosing cholangitis, and unremitting pouchitis.

Abstract
BACKGROUND Restorative proctocolectomy (RPC) is the criterion standard surgical treatment for ulcerative colitis (UC). Restorative proctocolectomy is indicated for UC that is refractory to medical treatment, for emergency conditions, and in case of neoplastic transformation. The procedure substantially reduces the risk of UC-associated dysplasia/neoplasia. However, after RPC surgery, even with mucosectomy, cancers of the pouch and/or the anal-transitional zone (ATZ) have been reported with increasing frequency since the first report in 1984. This review highlights pouch-related dysplastic and neoplastic transformation, prevalence and adverse events, risk factors and surveillance following surgery for UC. METHODS Reports in the literature about patients undergoing pouch surgery from different institutions reported through May 2010 were reviewed to identify patients who developed these complications, and an attempt was made to develop a rational follow-up policy based on the data available. RESULTS To date, there are 43 reported cancers of the pouch or inlet after RPC for UC: 16 from retrospective series, 1 from a prospective study, and 26 in case reports. Thirty patients underwent mucosectomy and 13 had stapled anastomoses. To date, the number of 28 patients has been diagnosed with dysplasia after RPC for UC. Mucosectomy was performed in 27 of them and in 1 a stapled anastomosis was constructed without mucosectomy. In all cases reviewed, the time interval from the onset of UC to dysplasia/neoplasia was over 10 years. CONCLUSION Neoplastic lesions occurring in UC patients after RPC have been shown to be absolutely inevitable. Even mucosectomy does not completely eliminate the risk. There is little evidence to support routine biopsy of the ileal mucosa or the anal-transition zone except in patients with histological type C changes, sclerosing cholangitis, and unremitting pouchitis in the ileal mucosa. Such patients should be selected for endoscopic surveillance to detect dysplasia preceding pouch adenocarcinoma.

Abstract
Approximately 30% of the patients with ulcerative colitis (UC) would ultimately require colectomy for medically refractory UC or UC-associated neoplasia. Restorative proctocolectomy with ileal pouch-anal anastomosis has become the surgical treatment of choice for these patients. However, this procedure does not completely abolish the risk for neoplasia of the pouch. The main risk factor for pouch neoplasia is a preoperative diagnosis of UC-associated dysplasia or cancer. Although the natural history and prognosis of pouch dysplasia are not clear, mortality associated with pouch cancer, once diagnosed, appears to be high. Conversely, not all pouch neoplasia follows the chronic inflammation-dysplasia-cancer sequence, which makes pouch endoscopy with biopsy, the current gold standard for surveillance, challenging. In addition, the findings that pouch neoplasia is not common and that pouch endoscopy still misses dysplasia lead to controversy on the need and time interval of routine endoscopic surveillance. However, based on reports in the literature and their own experience, the authors recommend surveillance endoscopy to be performed in patients at risk, such as those with a precolectomy diagnosis of UC-associated neoplasia. This review appraises issues in the prevalence and incidence, risk factors, technical aspects of pouch construction, clinical and pathological features, natural history, surveillance examination, diagnosis, and management of pouch neoplasia.

Abstract
BACKGROUND & AIMS Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has substantially reduced the risk for ulcerative colitis (UC)-associated dysplasia or cancer (neoplasia). We characterized features, risk factors, and outcomes of pouch neoplasia in patients with inflammatory bowel disease in a historical cohort study. METHODS A total of 3203 patients with a preoperative diagnosis of inflammatory bowel disease underwent restorative proctocolectomy with IPAA from 1984 to 2009 at the Cleveland Clinic. Demographic, clinical, and endoscopic data were reviewed and samples were examined by histological analyses. Univariable and Cox regression analyses were performed. RESULTS Cumulative incidences for pouch neoplasia at 5, 10, 15, 20, and 25 years were 0.9%, 1.3%, 1.9%, 4.2%, and 5.1%, respectively. Thirty-eight patients (1.19%) had pouch neoplasia, including 11 (0.36%) with adenocarcinoma of the pouch and/or the anal-transitional zone (ATZ), 1 (0.03%) with pouch lymphoma, 3 with squamous cell cancer of the ATZ, and 23 with dysplasia (0.72%). In the Cox model, the risk factor associated with pouch neoplasia was a preoperative diagnosis of UC-associated cancer or dysplasia, with adjusted hazard ratios of 13.43 (95% confidence interval: 3.96-45.53; P < .001) and 3.62 (95% confidence interval: 1.59-8.23; P = .002), respectively. Mucosectomy did not protect against pouch neoplasia. CONCLUSIONS Risk for neoplasia in patients with UC and IPAA is small and not eliminated by colectomy or mucosectomy. A preoperative diagnosis of dysplasia or cancer of colon or rectum is a risk factor for pouch dysplasia or adenocarcinoma.

Abstract
Background Small bowel adenocarcinomas (SBAs) are rare carcinomas. They are asymptomatic and usually neither endoscopy nor contrast studies are performed for screening Case presentation A 72-year-old Japanese male had a positive fecal occult blood test at a regular check-up in 2006. He suffered appendicitis and received an ileosigmoidostomy in 1966. A colonoscopy revealed an irregular mucosal lesion with an unclear margin at the ileum side of the anastomosis. A mucosal biopsy specimen showed adenocarcinoma histopathologically. Excision of the anastomosis was performed for this patient. The resected specimen showed a flat mucosal lesion with a slight depression at the ileum adjacent to the anastomosis. Histological examination revealed a well differentiated intramucosal adenocarcinoma (adenocarcinoma in situ). Immunohistological staining demonstrated the overexpression of p53 protein in the adenocarcinoma. Conclusion Adenocarcinoma of the ileum at such an early stage is a very rare event. In this case, there is a possibility that the ileosigmoidostomy resulted in a back flow of colonic stool to the ileum that caused the carcinogenesis of the small intestine.

Abstract
The occurrence of adenocarcinoma following ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) is an infrequent and but potentially lethal complication. We have seen 1 such case among 520 IPAAs performed in our group practice between 1978 and February 2008. We have added this case to a review of 25 previously reported cases of adenocarcinoma of the pouch or outflow tract following IPAA for UC. Our conclusions are 1) that post-IPAA cancer can occur following either mucosectomy or stapled anastomosis; 2) that this malignancy can occur after IPAA performed for UC either with or without neoplasia; and 3) that this complication is seen whether or not the initial cancer or dysplasia had involved the rectum.

Abstract
While the overall incidence of pouchitis is low, extensive research continues at clinical and experimental levels in attempts to unravel its etiology. The ileal pouch and pouchitis together represent a unique in vivo opportunity to study mucosal adaptation and inflammation in depth. In the recent past, molecular data relating to pouchitis has significantly expanded. These data provide invaluable insight into intracellular and extracellular events that underpin mucosal adaptation and inflammation. Advances in classification, risk factor evaluation, and prevention have meant that a review of this data, as well as its relationship to our current understanding of pouchitis, is both timely and warranted. Therefore, the aim of this review is to summarize recent data in the context of the established literature.

Abstract
Adenocarcinomas in relation to the ileal J-pouch after restorative proctocolectomy for ulcerative colitis have been recently reported with increasing frequency. All previously reported cases have occurred in patients with their ileal pouch in situ. We report a case of adenocarcinoma in the anal canal 11 years after removal of a failed ileal J-pouch. Mucosectomy had been performed at the restorative proctocolectomy. The anus had been left in place at the pouch excision because of severe fibrosis in the pelvis. If it is decided to remove an ileal pouch permanently, a total abdominoperineal excision should be performed, particularly in patients with risk factors for cancer development.

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
This report describes an adenocarcinoma arising in the perineum 30 years after two-stage total proctocolectomy for ulcerative colitis. This is one of the longest intervals reported between resection and presentation with cancer and also the only case in which the tumor is clearly free of association with existing bowel. The mass originally presented as a perineal mucocele, an unusual complication of proctocolectomy for ulcerative colitis, and this is the first such mucocele to demonstrate malignant transformation.

Abstract
The development of intestinal carcinoma in the setting of inflammatory bowel disease (IBD) has been recognized as an unsavory outcome of chronic inflammation of the bowel. Numerous studies have recently documented the clinical and morphologic features of malignant transformation in this closely-followed group of patients. This article highlights the recent findings of these population-based studies with specific attention to surgical concepts and frames these data in the context of surgical approaches to cancer arising in inflammatory disease. Specifically, the authors address the pathobiology of malignant transformation, the management of colorectal cancer in inflammatory bowel disease, the development of dysplasia in ulcerative colitis, surveillance of patients who have IBD, chemoprevention of cancer, and special features of surgical oncologic management.

Abstract
Abstract
Background
The aim of this systematic review was to assess the prevalence and site of dysplasia after restorative proctocolectomy (RPC) for ulcerative colitis (UC), and to identify risk factors that could be used in a surveillance programme.
Methods
Medical databases were searched for potentially relevant publications between 1978 and 2006. Studies that dealt with RPC for UC and postoperative surveillance were included. Two researchers independently performed study selection, quality assessment, data extraction and analysis.
Results
Twenty-three observational studies and case series were included, with a total of 2040 patients. The pooled prevalence of confirmed dysplasia in the pouch, anal transitional zone or rectal cuff was 1·13 (range 0–18·75) per cent. The prevalence of high-grade dysplasia, low-grade dysplasia and indefinite for dysplasia was 0·15 (range 0–4·49), 0·98 (range 0–15·62) and 1·23 (range 0–25·28 per cent) respectively. Dysplasia was equally frequent in the pouch and rectal cuff or anal transitional zone. Dysplasia and cancer identified before or at operation seemed to be significant predictors of the development of dysplasia. Pouchitis and duration of follow-up were not of predictive value.
Conclusion
Although based on low-level evidence from uncontrolled studies, the prevalence of dysplasia observed after RPC was remarkable. A surveillance programme that takes into account the risk factors found is therefore advocated.

Abstract
OBJECTIVE Restorative proctocolectomy (RPC) with or without mucosectomy is the treatment of choice for most patients with ulcerative colitis (UC) requiring surgery. The ileal mucosa in the reservoir and the anorectal columnar epithelium below the ileo-anal anastomosis are at risk of neoplastic transformation. METHOD The literature has been reviewed to identify patients developing this complication and an attempt has been made to develop a rational follow-up policy based on the data available. RESULTS Dysplasia in the ileal reservoir is rare. It is associated with histological type C changes, sclerosing cholangitis and unremitting pouchitis in the ileal mucosa and to the presence of sclerosing cholangitis. Nine patients who have developed adenocarcinoma in the residual anorectal mucosa and seven in the reservoir have been reported in the literature. A further hitherto unreported patient treated by the authors brings the total to 17 patients. Twelve of these had histopathological data on either dysplasia or carcinoma in the original operative specimen. The time intervals from the onset of UC and from the RPC to the development of cancer were 120-528 (median 246) and 16-216 (median 60) months respectively. Cancer appeared to be related to the duration of disease rather than to the interval from RPC. In all the reported patients the interval from the onset of UC was 10 years. CONCLUSION Based on these data a surveillance programme should begin at 10 years from the onset of disease. Patients with dysplasia or carcinoma in the original specimen, those with type C ileal mucosal changes and patients with sclerosing cholangitis should be selected for surveillance. This will involve multiple biopsies of the ileal reservoir and the anorectal mucosa below the ileo-anal anastomosis.
