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.

Incidence and Risk Factors of Cancer in the Anal Transitional Zone and Ileal Pouch following Surgery for Ulcerative Colitis and Familial Adenomatous Polyposis. Cancers (Basel) 2022; 14:cancers14030530. [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
BACKGROUND The predictive factors for chronic pouchitis after ileal pouch-anal anastomosis (IPAA) in pediatric-onset ulcerative colitis (UC) remain unclear. This study evaluated the predictive factors for chronic pouchitis after IPAA in patients with pediatric UC. METHODS The data from 52 patients with pediatric-onset UC who underwent IPAA in Mie University Hospital were retrospectively reviewed. The endoscopy surveillance was performed yearly or at the timing of the symptom. Chronic pouchitis was defined as antibiotic-dependent/-refractory and relapsing cases. Potential predictors of chronic pouchitis were analyzed. RESULTS During the first 5 years after IPAA, pouchitis was identified in 32.7%. Of these patients, 12 (70.6%) developed chronic pouchitis. The predictor of chronic pouchitis was a preoperative history of immunomodulator use before IPAA (p = 0.04). Life table analysis revealed that patients with chronic pouchitis tended to develop pouchitis earlier after IPAA than did patients without chronic pouchitis (p = 0.012). Receiver operating characteristic curve analysis showed that the occurrence of pouchitis within 15 months after IPAA surgery predicted the development of chronic pouchitis (sensitivity, 92%; specificity, 80%). CONCLUSION In pediatric patients with UC, the predictive factors for chronic pouchitis are immunomodulator use and early occurrence of the first episode of pouchitis within 15 months after IPAA.

Abstract
BACKGROUND The predictive factors for the development of pouchitis after ileal pouch-anal anastomosis (IPAA) in pediatric-onset ulcerative colitis (UC) have not been well investigated. The present study aimed to determine the predictive factors for the development of pouchitis after IPAA in the pediatric UC population. METHODS The data from 54 patients with pediatric-onset UC who underwent IPAA in Mie University Hospital between 2000 and 2017 were retrospectively reviewed. A modified pouchitis disease activity index of ≥5 was defined as pouchitis. Potential preoperative, intraoperative, and postoperative predictors for pouchitis including various demographic and clinical variables were analyzed using Cox regression analysis, Students' t-tests, Mann-Whitney U tests, and Kaplan-Meier curves. The optimal cutoff value for continuous variables was determined using the receiver operating characteristic curve analysis. RESULTS Pouchitis was identified in 17 (31.5%) patients within 5 y of follow-up. In multivariable analysis, the independent predictors for pouchitis were preoperative cumulative steroid dose of >10,000 mg (P = 0.0056) and >65% neutrophils just before IPAA (P = 0.032). Multivariate analysis revealed that the independent predictors of pouchitis were a total steroid dose of >10,000 mg (P = 0.0002) and a neutrophil percentage of >65% (P = 0.0078). No patient for whom both of these independent predictors were negative developed pouchitis, whereas >40% of patients who had one or both predictors developed pouchitis. CONCLUSIONS In pediatric patients with UC, the predictive factors for pouchitis development are a greater cumulative total dose of steroids and a greater percentage of neutrophils before IPAA.

Abstract
Colitis-associated cancer is a relatively rare form of cancer with an unclear pathogenesis. Colitis-associated cancer serves as a prototype of inflammation-associated cancers. Advanced colonoscopic techniques are considered standard of care for surveillance in patients with long-standing colitis, especially those with other risk factors, including sclerosing cholangitis and a family history of colorectal cancer. When colitis-associated cancer is diagnosed, the standard operation involves total proctocolectomy. Restorative procedures and surveillance after colectomy require special considerations. In these contexts, new 3-dimensional human models may be used to usher in personalized medicine.

Abstract
OBJECTIVES Predictive factors for the development of pouchitis after ileal pouch-anal anastomosis (IPAA) in children have not been well studied. In this retrospective study, the incidence and risk factors that predict pouchitis in children with IPAA will be identified. METHODS The records of patients who underwent IPAA surgery at Children's Hospital of Wisconsin between January 2000 and December 2013 were reviewed retrospectively. Patients with clinical, endoscopic, and histological findings consistent with pouchitis were identified. The groups of patients with and without pouchitis or chronic pouchitis were compared to determine which demographic, pathological, or disease characteristics may serve as predictive factors for the development of pouchitis or chronic pouchitis. RESULTS Out of a total of 60 patients who underwent IPAA, preoperative diagnosis was ulcerative colitis (UC) in 43 and familial adenomatous polyposis (FAP) in 17. Pouchitis was identified in 24 (56%) patients with UC and 2 (12%) patients with FAP. Subgroup analysis of patients with UC revealed that chronic pouchitis occurred in 15 (35%) patients. The median follow-up period from construction of the IPAA was 35 months (range 4.59-104.26 months). The study analysis revealed that a higher Pediatric Ulcerative Colitis Activity Index score at the time of diagnosis was a significant predictive factor for both pouchitis (P = 0.001) and chronic pouchitis (P = 0.02). CONCLUSIONS Patients with UC and a higher PUCAI score at the time of diagnosis have a higher risk for developing pouchitis.

Abstract
AIM The study's aim is to determine long-term outcomes in a large cohort of pediatric and young adult patients who underwent proctocolectomy with ileal pouch anal anastomsis (IPAA) for ulcerative colitis (UC). METHODS Patients diagnosed with UC in childhood or adolescence (age≤21years) who underwent IPAA in childhood, adolescence, or young adulthood between 1982 and 1997 were contacted to determine pouch history, complications, and quality of life. RESULTS Data were obtained from 74 patients out of a previously reported cohort. Median age at diagnosis of UC was 15years and at surgery was 18years. Median follow-up was 20years. Complications during follow-up were pouchitis (45%), strictures (16%), fistulae (30%), obstruction (20%), and change of diagnosis to Crohn's (28%). Twenty-three percent reported no complications. Fourteen percent had pouch failure, with Crohn's and fistulae reported to be the most frequent complications. Seventy-nine percent reported being very satisfied at 20years follow-up. CONCLUSION To our knowledge, this study represents the largest cohort with the longest follow-up of pediatric and young adult patients undergoing IPAA for UC. Change in diagnosis to Crohn's and development of fistulae are risk factors for pouch failure. Despite reported complications, IPAA remains an excellent option for pediatric patients with UC.

Abstract
The number of ileostomies created for benign diseases such as familial adenomatous polyposis and ulcerative colitis is increasing. Long-term ileostomies are prone to develop various complications over time. Ileostomy site carcinoma is a well-established complication in ulcerative colitis and familial adenomatous polyposis that have undergone total colectomy. However, no case of ileostomy site carcinoma has been described in a patient with Hirschprung's disease. We present the first case of adenocarcinoma at an ileostomy site in a patient with Hirschprung's disease with retroviral disease.

Abstract
Pediatric severe ulcerative colitis that is resistant to current medical treatment can successfully be managed surgically with a colectomy, ileal pouch creation and pouch-anal anastomosis. Key issues that should be considered and discussed before the pouch option can be offered include alternative surgical procedures, pouch function expectations, risk of surgical leak, pelvic sepsis, anastomotic strictures, acute and chronic pouch inflammation, Crohn's disease of the pouch and risk of reduced fertility for females. A long-term risk is malignancy of the residual colonic tissue. The decision to proceed with a pouch or not poses a substantial emotional burden to the child and family. Despite the risk of surgical complications and pouch inflammatory and functional challenges, the overwhelming majority of children and their families are satisfied with their pouch surgery outcomes. Further study is needed to assess preoperative risk predictors, prevention and treatment of complications.

Abstract
Although restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the surgical treatment of choice for patients with refractory ulcerative colitis (UC) or UC with dysplasia, surgical, inflammatory, and noninflammatory adverse sequelae are common. Pouchitis, representing a spectrum of disease phenotypes, is the most common long-term complication of IPAA. De novo Crohn disease (CD) of the pouch can occur in patients with a preoperative diagnosis of UC. Differential diagnosis between fibrostenotic or fistulizing CD and surgery-associated strictures, sinuses, and fistulas often requires a combined assessment of symptom, endoscopy, histology, radiography, and examination under anesthesia. There is a role for endoscopic therapy for stricturing complications of IPAA. Chronic antibiotic-refractory pouchitis, refractory cuffitis, as well as fibrostenotic or fistulizing CD of the pouch are the leading late-onset causes for pouch failure.

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
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.

Um JW, M'Koma AE. Pouch-related dysplasia and adenocarcinoma following restorative proctocolectomy for ulcerative colitis. Tech Coloproctol 2011; 15:7-16. [PMID: 21287223 DOI: 10.1007/s10151-010-0664-2] [Citation(s) in RCA: 26] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/09/2010] [Accepted: 12/04/2010] [Indexed: 02/05/2023]
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 The risk of developing cancer in the ileal pouch of patients with surgery for ulcerative colitis has not been defined. Dysplasia in the pouch is quite rare. Although some suggest pouch surveillance based on previous histological assessments, there are no guidelines for surveillance of these patients. The aim of our study was to investigate that risk and identify time intervals for ileoanal pouch surveillance. METHODS Endoscopy and biopsies of the ileal pouch were performed at 3, 6, and/or 12 months after ileal pouch-anal anastomosis (IPAA) became functional. Biopsies were evaluated by two pathologists using Riddel's criteria. Interim data analysis using descriptive statistics is reported. RESULTS Thirty-eight patients have entered the study. Average patient age at 3, 6, and 12 months of surveillance was 39.1, 36.8, and 39.1 years, respectively. Average disease duration was 8.2 years. Ten of 38 cases (26%) had colonic dysplasia prior to surgery. Dysplasia within the pouch was reported in one patient 6 months after IPAA became functional. This patient demonstrated no dysplasia at 12 months or statistical divergence by age, duration of disease or history of colonic dysplasia prior to IPAA. No subgroup of patients with dysplasia was identified to calculate cumulative risk or perform comparative statistical analysis. CONCLUSION A study with longer follow-up after IPAA should precede any attempt to recommend routine surveillance. However, the finding of dysplasia early after surgery underscores the importance of early pouch surveillance in our population, at least until definite predisposing variables are identified.

Abstract
Guidelines for clinical practice are aimed to indicate preferred approaches to medical problems as established by scientifically valid research. Double-blind placebo controlled studies are preferable, but compassionate-use reports and expert review articles are used in a thorough review of the literature conducted through Medline with the National Library of Medicine. When only data that will not withstand objective scrutiny are available, a recommendation is identified as a consensus of experts. Guidelines are applicable to all physicians who address the subject regardless of specialty training or interests and are aimed to indicate the preferable but not necessarily the only acceptable approach to a specific problem. Guidelines are intended to be flexible and must be distinguished from standards of care, which are inflexible and rarely violated. Given the wide range of specifics in any health-care problem, the physician must always choose the course best suited to the individual patient and the variables in existence at the moment of decision. Guidelines are developed under the auspices of the American College of Gastroenterology and its Practice Parameters Committee and approved by the board of trustees. Each has been intensely reviewed and revised by the Committee, other experts in the field, physicians who will use them, and specialists in the science of decision analysis. The recommendations of each guideline are therefore considered valid at the time of composition based on the data available. New developments in medical research and practice pertinent to each guideline will be reviewed at a time established and indicated at publication to assure continued validity. The recommendations made are based on the level of evidence found. Grade A recommendations imply that there is consistent level 1 evidence (randomized controlled trials), grade B indicates that the evidence would be level 2 or 3, which are cohort studies or case-control studies. Grade C recommendations are based on level 4 studies, meaning case series or poor-quality cohort studies, and grade D recommendations are based on level 5 evidence, meaning expert opinion.

Abstract
OBJECTIVE Long-term outcomes of restorative proctocolectomy for pediatric-onset ulcerative colitis are unclear. METHODS Questionnaires on health outcomes and quality of life were mailed to patients with childhood-onset ulcerative colitis who had undergone proctocolectomy with ileoanal anastomosis in 2 university hospitals between 1985 and 2005. Investigators not involved in the surgical management of the patients approached participants. Matched control children were randomly chosen from the Population Register Centre of Finland. RESULTS Fifty-two (66%) patients and 117 (37%) controls responded. After a mean follow-up of 10 years, at least 1 surgical complication had occurred in 39 (75%) patients, and 28 (54%) had undergone reoperation. Only 1 failure of ileoanal anastomosis occurred. Ulcerative colitis had been reclassified as Crohn disease in 6 (12%) patients. Pouchitis occurred in 37 (73%) patients. The median stool frequency was 5 for day and 1 for night, but 46% used medication to control stool frequency. Nighttime soiling was reported by 56% of the patients. The mean overall quality-of-life score, the mean BMI (22 kg/m(2) for both), and the number of subjects (aged >20 years) with offspring (14% vs 15%) was similar to the population-based controls. CONCLUSIONS Stool frequency after restorative proctocolectomy in children with ulcerative colitis is stable and comparable to those of adult patients. Although nighttime incontinence is common, general health status and overall quality of life are comparable to the normal population.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis with or without mucosectomy has become the procedure of choice in patients with long-standing ulcerative colitis complicated by malignancy or medically refractory disease and for familial polyposis syndrome. Some reports have demonstrated the development of malignancy at the ileoanal anastomosis. We present a recent series of five patients who developed adenocarcinoma in the middle of their ileal pouch including the first case of pouch carcinoma in a patient who underwent pouch formation for ulcerative colitis. We discuss their presentation and management. Development of ileal pouch cancers, while rare, has been seen with increasing frequency in our practice. Patients with long-standing ileal pouches may benefit from routine surveillance of the pouch as often as every six months, which can be performed quickly and easily in the office using flexible endoscopy.

Abstract
Restorative procto-colectomy with ileal pouch anal anastomosis has become the most common elective surgical procedure for patients with ulcerative colitis and is becoming popular in those with familial adenomatous polyposis coli. The procedure itself is primarily carried out in specialist surgical centres but an increasing number are being performed and followed up in district general hospitals. These patients are now filtering through general surgical and gastroenterology clinics and are frequently seen in primary care. Pouchitis, an inflammatory condition of the ileal pouch, has become the third most important form of inflammatory bowel disease. As research develops in this area, other complications are being found. The aim of this review is to provide an up-to-date, evidence-based approach to the clinical management of these patients.

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
Cancer in children may be mistakenly diagnosed as inflammatory bowel disease (IBD), and specific cancers may develop in patients who truly have IBD. Ulcerative colitis patients historically carry an increased risk of colorectal adenocarcinoma, but current practices of surveillance and early surgery may have an impact on this. Crohn's disease patients require surveillance for colon cancer, but are also likely to be at increased risk for small bowel tumors and lymphoma. Some malignancies affecting IBD patients are sequelae of immunomanipulation, performed in the interest of IBD therapy itself. Knowing the cancer risks associated with IBD and those associated with agents used for IBD treatment, and practicing long-term surveillance for these tumors, are central components of caring for patients with IBD. Lessons learned from the fields of oncology and bone marrow transplantation may provide future directions and potential cures in IBD.

Abstract
PURPOSE Inflammation, villous atrophy, colonic metaplasia, and dysplasia have been observed within the mucosa of ileal pelvic pouches after restorative proctocolectomy. This study was designed to determine the prevalence of mucosal dysplasia in ileal pouch and any associated risk factors. METHODS Prospectively registered patients having restorative proctocolectomy were recruited. A cross-sectional study was performed using a questionnaire focusing on disease history, functional results, and pouchitis after surgery. Participants underwent screening endoscopic pouch examination using sigmoidoscopy. Mucosal biopsies were taken from six specific locations in the pouch from proximal ileal-pouch (inflow) to ileoanal anastomosis. All biopsies were performed under strict surveillance protocol regardless of patients' symptoms. Biopsies were interpreted by two pathologists unaware of each other's report. RESULTS A total of 138 patients completed the protocol. Colectomy specimens from restorative proctocolectomy showed chronic ulcerative colitis in 118 (85.6 percent), familial adenomatous polyposis in 10 (7.2 percent), Crohn's colitis in 2 (1.4 percent), and indeterminate colitis in 8 (5.8 percent) patients. Twenty-two patients (18.3 percent) had dysplasia and eight (6.7 percent) had invasive cancer found in colectomy specimens after restorative proctocolectomy. Median interval between proctocolectomy and pouch biopsy was 5.4 years. Inflammatory changes were present in a majority of specimens, but these did not correlate with clinical history of pouchitis. No villous atrophy was identified. Pouch biopsies from only one patient were indefinite for dysplasia. Subsequent biopsies were negative. CONCLUSIONS Clinical and microscopic evidence of ileal-pouch inflammation is common. Ileal-pouch mucosal dysplasia is uncommon, occurring in only 1 of 138 patients. Villous atrophy and colonic metaplasia were not observed in this series. Routine pouch surveillance with biopsies may not be warranted.

Abstract
PURPOSE Polypoid lesions rarely occur in the ileal pouch in ulcerative colitis patients after restorative proctocolectomy. Clinical features, malignant potential, and management of pouch polyps have not been characterized. METHODS We identified 23 ulcerative colitis patients with large polyps (size> or =1 cm) of the ileal pouch from our 2,512-case ulcerative colitis pouch database. Demographic, clinical, endoscopic, and histologic data were reviewed. The Pouchitis Disease Activity Index symptom score (range, 0-6) was used to quantify patients' symptoms before and after polypectomy. RESULTS Of the 23 patients, 95.7 percent (22 patients) had pouch endoscopy indicated for the evaluation of symptoms when polyps were detected, and 60.9 percent of patients had the polyps in the pouch, 26.1 percent in the anal transitional zone, and 21.7 percent in the afferent limb. The mean size of pouch polyps was 1.9 cm +/- 1 cm. Twenty-one patients (91.3 percent) had concomitant pouchitis, cuffitis, or Crohn's disease. On histology, 21 patients (91.3 percent) had inflammatory-type polyps, and 2 (8.7 percent) had dysplastic or malignant polyps. In 18 patients who had endoscopic polypectomy with concurrent medical therapy, the prepolypectomy and postpolypectomy mean symptom scores were 3.4 +/- 1.7 and 1.1 +/- 1.2 points, respectively (P = 0.015). Two patients (8.7 percent) had pouch excision for malignancy or for concomitant chronic refractory pouchitis. CONCLUSIONS The majority of patients with large ileal pouch polyps were symptomatic. These polyps were typically detected on the background of pouchitis, cuffitis, or Crohn's disease. Although the majority of polyps were inflammatory type, polyps in two patients were dysplastic or malignant. Endoscopic polypectomy with concomitant medical therapy seemed to improve patients' symptom scores.

Abstract
BACKGROUND Studies of pediatric inflammatory bowel disease (IBD) have varied in the criteria used to classify patients as having Crohn disease (CD), ulcerative colitis (UC), or indeterminate colitis (IC). Patients undergoing an initial evaluation for IBD will often undergo a series of diagnostic tests, including barium upper gastrointestinal series with small bowel follow-through, abdominal CT, upper endoscopy, and colonoscopy with biopsies. Other tests performed less frequently include magnetic resonance imaging scans, serological testing, and capsule endoscopy. The large amount of clinical information obtained may make a physician uncertain as to whether to label a patient as having CD or UC. Nevertheless, to facilitate the conduct of epidemiological studies in children, to allow the entry of children into clinical trials, and to allow physicians to more clearly discuss diagnosis with their patients, it is important that clinicians be able to differentiate between CD and UC. METHODS A consensus conference regarding the diagnosis and classification of pediatric IBD was organized by the Crohn's and Colitis Foundation of America. The meeting included 10 pediatric gastroenterologists and 4 pediatric pathologists. The primary aim was to determine the utility of endoscopy and histology in establishing the diagnosis of CD and UC. Each member of the group was assigned a topic for review. Topics evaluated included differentiating inflammatory bowel disease from acute self-limited colitis, endoscopic and histological features that allow differentiation between CD and UC, upper endoscopic features seen in both CD and UC, ileal inflammation and "backwash ileitis" in UC, patchiness and rectal sparing in pediatric IBD, periappendiceal inflammation in CD and UC, and definitions of IC. RESULTS Patients with UC may have histological features such as microscopic inflammation of the ileum, histological gastritis, periappendiceal inflammation, patchiness, and relative rectal sparing at the time of diagnosis. These findings should not prompt the clinician to change the diagnosis from UC to CD. Other endoscopic findings, such as macroscopic cobblestoning, segmental colitis, ileal stenosis and ulceration, perianal disease, and multiple granulomas in the small bowel or colon more strongly suggest a diagnosis of CD. An algorithm is provided to enable the clinician to differentiate more reliably between these 2 entities. CONCLUSIONS The recommendations and algorithm presented here aim to assist the clinician in differentiating childhood UC from CD. We hope the recommendations in this report will reduce variability among practitioners in how they use the terms "ulcerative colitis," "Crohn disease," and "indeterminate colitis." The authors hope that progress being made in genetic, serological, and imaging studies leads to more reliable phenotyping.

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.

Abstract
OBJECTIVE The aim of this study was to review the results after stapled restorative proctocolectomy among children with refractory ulcerative colitis. PATIENTS AND METHODS Clinical records of 16 consecutive children with refractory ulcerative pancolitis undergoing colectomy and stapled straight ileoanal anastomosis at a median age of 8.3 years (range, 3.1-14.9 years) were reviewed. Periodical clinical examinations and endoscopies with biopsies above (terminal ileum) and below (columnar cuff) the anastomosis were carried out during follow-up. Median follow-up after bowel restoration lasted 5.3 years (range, 1.2-9.6 years). RESULTS Two major complications occurred (12.5%), 1 episode of sepsis treated conservatively and 1 bowel perforation proximal to the anastomosis treated with a temporary diverting ileostomy. All the anastomoses were functional at the end of the study. The columnar cuff averaged 2.6 cm in length and presented signs of persistent inflammation (cuffitis) in 94% of children. Inflammation responded poorly to any medical treatment but was symptomatic in 1 case only. Ileal inflammation was detected endoscopically in 31% of patients and histologically in 62.5%. No case of dysplasia or cancer was recorded. At final follow-up, children had an average of 7.1 +/- 3.1 bowel movements per day; full daytime and nighttime continence were achieved in 87.5% and 62.5% of cases, respectively. A severe inflammation of the columnar cuff was associated with an increased risk of nighttime incontinence. CONCLUSIONS Stapled ileoanal anastomosis in children with pancolitis is associated with low morbidity. Refractory cuffitis persists in almost all patients but is mostly asymptomatic, although it could be associated with nighttime incontinence.

Abstract
AIM Some of the rare complications reported in patients with an ileopouch anal anastomosis (IPAA) after coloectomy for chronic ulcerative colitis are dysplasia and carcinoma. The supposed pathway is for the ileal pouch mucosa to go through adaptational changes then is to progress through the phases of chronic pouchitis, dysplasia and subsequently to adenocarcinoma. In many of these studies however, the dysplasia-cancer sequence is inconclusive since the carcinoma might have developed from the ileal mucosa itself or from residual viable rectal mucosa left behind. The purpose of this study was therefore to study the long-term ileal mucosal adaptation patterns and the incidence and grading of dysplasia in the ileal pouch mucosa in patients previously operated on for ulcerative proctocolitis. PATIENTS AND METHODS Forty-five patients who had been operated on with an IPAA (25 males/20 females), with a median age of 54 years (range 34-76), were invited for clinical examination and pouch endoscopy including mucosal biopsies. The duration of their colitis until surgery was median 6 years (range 1-28) and the time median interval from start of disease until time of follow up 24.8 years (range 17-46). Three independent pathologists from two different centres reviewed sequential mucosal biopsies taken from separate sites of the pouch for dysplasia and mucosal adaptation patterns. RESULTS The type C pattern with a severe inflammation in lamina propria together with severe atrophy of villi, sometimes with ulceration and granulation tissue, was observed by the two pathologists from one centre in 15 of 45 (33.3%) patients and in 11 (24.4%) of 45 by the third pathologist, respectively. As regards dysplasia one pathologist group evaluated 2/45 (4.4%) cases as low-grade dysplasia while the third pathologist considered one of these cases as indefinite for dysplasia and one as reactive. There was in this respect full agreement between the two centres in 43 (95.6%) of 45 cases. Neither high-grade dysplasia nor invasive carcinoma was diagnosed. CONCLUSION Dysplastic transformation within the ileal pouch mucosa in patients operated for ulcerative proctocolitis is rare even after a long follow-up. These results are reassuring for both patients and surgeons. There seem to be no solid grounds to support routine surveillance for dysplasia in the ileal pouch mucosa in these patients. The surveillance for neoplastic changes in the remaining muscular/epithelial cuff is a separate issue however.

Abstract
The two major inflammatory bowel diseases, Crohn's disease (CD) and ulcerative colitis (UC), represent clinicopathologic entities that traditionally have been diagnosed on the basis of a combination of clinical, radiologic, endoscopic, and histologic features. Serum perinuclear antineutrophil cytoplasmic antibodies (pANCA) and anti-Saccharomyces cerevisiae antibodies (ASCA) have recently been added to our diagnostic armamentarium. Several studies have demonstrated that UC-associated pANCAs recognize nuclear antigens. Additional studies have demonstrated that the pANCA human monoclonal antibody (mAb) Fab 5-3 reacts with histone H1 and with bacterial and mycobacterial antigens. Several reports have suggested that, in CD, pANCA and ASCA are correlated with colonic and small bowel disease respectively. One study found that higher ASCA levels were correlated with more aggressive CD. Serology may prove to be useful in predicting the evolution of indeterminate colitis. Magnetic resonance imaging (MRI) and leukocyte scintigraphy hold promise in identifying inflammatory CD. MRI enteroclysis is useful in identifying both luminal small bowel disease and extraluminal complications. A recent study of surveillance colonoscopy in extensive Crohn's colitis showed a high risk of dysplasia and cancer.

Abstract
Pouchitis is an inflammation of unknown origin occurring in the ileal pouch after IPAA. It is considered by many to be a form of ulcerative colitis that recurs in the pouch and rarely, if ever, occurs in patients with FAP. Most patients respond to a short course of antibiotics. When remission cannot be maintained or the disease is nonresponsive to prolonged treatment with antibiotics, anti-inflammatory agents or steroids may be useful. A variety of alternative drugs have been tried with mixed success and should be considered as experimental. Rarely, when pouchitis is refractory to medical management, excision of the pouch may be required.

Abstract
OBJECTIVE To evaluate continued experience with a one-stage stapled ileoanal pouch procedure without temporary ileostomy diversion. SUMMARY BACKGROUND DATA Most centers perform colectomy, proctectomy, and ileal pouch anal anastomoses (IPAA) with a protective ileostomy. Following a previous report, the authors performed 126 additional stapled IPAA procedures for ulcerative colitis and familial adenomatous polyposis, of which all but 2 were without an ileostomy. Outcomes in these patients question the need for temporary ileal diversion, with its complications and need for subsequent surgical closure. METHODS Two hundred one patients underwent a stapled IPAA since May 1989, 192 as a one-stage procedure without ileostomy, and 1 with a concurrent Whipple procedure for duodenal adenocarcinoma. Patient charts were reviewed or patients were contacted by phone to evaluate their clinical status at least 1 year after their surgery. RESULTS Among the patients who underwent the one-stage procedure, 178 had ulcerative colitis (38 fulminant), 5 had Crohn's disease (diagnosed after IPAA), 1 had indeterminate colitis, and 8 had familial adenomatous polyposis. The mean age was 38 +/- 7 (range 7--70) years; there were 98 male patients and 94 female patients. The average amount of diseased tissue between the dentate line and the anastomosis was 0.9 +/- 0.1 cm, with 35% of the anastomoses at the dentate line. With 89% follow-up at 1 year or more (mean 5.1 +/- 2.4 years) after surgery, the average 24-hour stool frequency was 7.1 +/- 3.3, of which 0.9 +/- 1.4 were at night. Daytime stool control was 95% and night-time control was 90%. Only 2.3% needed to wear a perineal pad. Average length of hospital stay was 10 +/- 0.3 days, with 1.5 +/- 0.5 days readmission for complications. Abscesses or enteric leaks occurred in 23 patients; IPAA function was excellent in 19 of these patients (2 have permanent ileostomies). In patients taking steroids, there was no significant difference in leak rate with duration of use (29 +/- 8 with vs. 22 +/- 2 months without leak) or dose (32 +/- 13 mg with vs. 35 +/- 3 mg without leak). Two (1%) patients died (myocardial infarction, mesenteric infarction). CONCLUSIONS The triple-stapled IPAA without temporary ileal diversion has a relatively low complication rate and a low rate of small bowel obstruction, provides excellent fecal control, permits an early return to a functional life, and can be performed in morbidly obese and older patients.

Abstract
Three atypical colitides (and enterides) are collagenous colitis, lymphocytic colitis, and ileal pouchitis. Collagenous and lymphocytic colitis are similar inflammatory bowel disorders of unknown cause with symptoms including chronic watery diarrhea, occurring in middle age. Pouchitis is the most significant long-term complication in patients with ileoanal pouch anastomosis. The clinical and histologic features and management of these entities are discussed.
