Abstract
BACKGROUND Ileal pouch-anal anastomosis (IPAA) is the standard of care after total proctocolectomy for ulcerative colitis (UC). However, inflammation often develops in the pouch, leading to acute or recurrent/chronic pouchitis (R/CP). MicroRNAs (miRNA) are used as accurate diagnostic and predictive biomarkers in many human diseases, including inflammatory bowel diseases. Therefore, we aimed to identify an miRNA-based biomarker to predict the occurrence of R/CP in patients with UC after colectomy and IPAA. METHODS We conducted a retrospective study in 3 tertiary centers in France. We included patients with UC who had undergone IPAA with or without subsequent R/CP. Paraffin-embedded biopsies collected from the terminal ileum during the proctocolectomy procedure were used for microarray analysis of miRNA expression profiles. Deep neural network-based classifiers were used to identify biomarkers predicting R/CP using miRNA expression and relevant biological and clinical factors in a discovery cohort of 29 patients. The classification algorithm was tested in an independent validation cohort of 28 patients. RESULTS A combination of 11 miRNA expression profiles and 3 biological/clinical factors predicted the outcome of R/CP with 88% accuracy (area under the curve = 0.94) in the discovery cohort. The performance of the classification algorithm was confirmed in the validation cohort with 88% accuracy (area under the curve = 0.90). Apoptosis, cytoskeletal regulation by Rho GTPase, and fibroblast growth factor signaling were the most dysregulated targets of the 11 selected miRNAs. CONCLUSIONS We developed and validated a computational miRNA-based algorithm for accurately predicting R/CP in patients with UC after IPAA.

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
BACKGROUND Clostridium difficile infection (CDI) in patients with the ileal pouch after proctocolectomy has been increasingly recognized. We sought to evaluate the frequency and risk factors of CDI in patients with the primary or secondary discharge diagnosis of pouchitis in the United States. METHODS We reviewed the National Inpatient Sample of the Healthcare Cost and Utilization Project and identified patients admitted for pouchitis with underlying inflammatory bowel disease (IBD) or familial adenomatous polyposis (FAP), between 2010 and 2012. Cases with CDI were identified based on a concomitant primary or secondary discharge diagnosis for CDI. The frequency of CDI was estimated in patients with underlying IBD and FAP. Multivariable analysis was conducted to study the risk factors associated with CDI in those with pouchitis with underlying IBD. RESULTS A total of 3566 eligible patients with pouchitis were identified during the study period. Eighty-nine patients (2.5%) had CDI as a concomitant primary or secondary discharge diagnosis. CDI was identified in 2.6% (99.9% confidence interval [CI], 1.3-3.8) of pouchitis patients with underling IBD. None of the patients with pouchitis with underlying FAP were found to have CDI during the study period. Among pouchitis patients with underlying IBD, the presence of nonalcoholic fatty liver disease (odds ratio = 5.4; 95% CI, 1.5-19.9), obesity (odds ratio = 5.5; 95% CI, 1.4-21.4), or obstructive sleep apnea (odds ratio = 10.3; CI, 2.0-53.7) was associated with an increased risk of CDI. CONCLUSIONS It seems that CDI was limited to pouchitis with underlying IBD and rare in those with underlying FAP. Patients with nonalcoholic fatty liver disease, obesity, and obstructive sleep apnea are at an increased risk of C. difficile pouchitis among patients with IBD.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis has been the surgical treatment of choice for patients with ulcerative colitis who require surgery. Quality of life after this procedure is satisfactory in most cases; however, pouchitis is a troublesome condition involving inflammation of the ileal pouch. When a patient presents with symptoms of pouchitis, such as increased bowel movements, mucous and/or bloody exudates, abdominal cramps, and fever, endoscopy is essential for a precise diagnosis. The proximal ileum and rectal cuff, as well as the ileal pouch, should be endoscopically observed. The reported incidence of pouchitis ranges from 14% to 59%, and antibiotic therapy is the primary treatment for acute pouchitis. Chronic pouchitis includes antibiotic-dependent and refractory pouchitis. Intensive therapy including antitumor necrosis factor antibodies and steroids may be necessary for antibiotic-refractory pouchitis, and pouch failure may occur despite such intensive treatment. Reported risk factors for the development of pouchitis include presence of extraintestinal manifestations, primary sclerosing cholangitis, non-smoking, and postoperative non-steroidal anti-inflammatory drug usage. In the present review, we focus on the diagnosis, endoscopic features, management, incidence, and risk factors of pouchitis in patients with ulcerative colitis who underwent ileal pouch-anal anastomosis.

Abstract
BACKGROUND Colectomy for ulcerative colitis is associated with short- and long-term complications. Estimates of the frequency of such complications are variable and may have changed since the introduction of biological therapy. Understanding the true burden of surgical complications is important to clinicians in assessing risks and benefits of colectomy vs. continued medical therapy. AIM To ascertain the outcomes of colectomy and ileal pouch surgery in patients with ulcerative colitis in the biologics era. METHODS Embase, MEDLINE and The Cochrane Library were searched for studies (2002-2015) reporting the outcomes of colorectal procedures (total and subtotal colectomy, IPAA with J-, S-, W-pouch) in adults with ulcerative colitis. Conferences proceedings (2011-2015) were hand-searched. RESULTS We identified 28 studies (20,801 patients) reporting outcomes from procedures conducted from 2002-2015. Early complications (≤30 days post-operatively), reported in 10 studies, occurred in 9-65% of patients with ulcerative colitis; late complications (>30 days post-operatively) occurred in 17-55% of patients. Most frequent short-term complications: infectious complications and ileus (mean incidence 20% and 18%). Most frequent long-term complications: pouchitis, faecal incontinence and small bowel obstruction (mean incidence 29%, 21% and 17%). Rates of early infection and late pouch failure decreased from 22% and 13% in 2002-2009 to 11% and 2% in 2010-2015. The mean incidence of post-operative mortality was 1.0% across 11 studies. CONCLUSIONS Early and late complications arise in about one-third of patients undergoing surgery for ulcerative colitis. While colorectal surgical procedures are recommended for a specific group of patients, the post-operative complications associated with these procedures should not be underestimated.

Serology of Patients with Ulcerative Colitis After Pouch Surgery Is More Comparable with that of Patients with Crohn's Disease. Inflamm Bowel Dis 2015.

Abstract
BACKGROUND The serologic status of patients with ulcerative colitis (UC) who develop postoperative pouchitis was compared with that of patients with Crohn's disease (CD) and unoperated patients with UC. METHODS Pouch patients were stratified into normal pouch, acute/recurrent acute pouchitis, and chronic pouchitis/Crohn's-like disease of the pouch groups. Antibodies against glycans associated with CD (anti-Saccharomyces cerevisiae, anti-laminaribioside, anti-chitobioside, and anti-mannobioside carbohydrate antibodies [ASCA, ALCA, ACCA, and AMCA, respectively]) were detected and correlated with type of inflammatory bowel disease and pouch behavior. RESULTS A total of 501 patients with inflammatory bowel diseases were recruited: 250 (50%) CD, 124 (24.7%) unoperated UC, and 127 (25.3%) UC-pouch. At least 1 positive antibody was detected in 77.6% CD, 52.0% UC-pouch and 33.1% unoperated UC (P < 0.0001 for all). ACCA and AMCA prevalence in CD, UC-pouch and unoperated patients with UC were 33.2%, 24.4%, and 16.9% (P = 0.003 for all) and 35.2%, 26.8%, and 7.3%, respectively (P < 0.0001 for all). ALCA and ASCA were more prevalent in patients with CD than unoperated UC and UC-pouch patients. A longer interval since pouch surgery was associated with inflammatory pouch behavior: 12.45, 11.39, and 8.5 years for acute/recurrent acute pouchitis, chronic pouchitis/Crohn's-like disease of the pouch, and normal pouch, respectively, P = 0.01 for all. CONCLUSIONS The prevalence of the CD-associated anti-glycan antibodies ACCA and AMCA is significantly increased in UC-pouch patients, suggesting that pouch surgery may trigger differential immune responses to glycans. The finding that the serology of UC-pouch patients shares similarities with that of patients with CD supports the notion that those 2 inflammatory bowel diseases share a common pathogenic pathway.

Abstract
: Restorative proctocolectomy with ileal pouch-anal anastomosis is the standard surgical treatment modality for patients with ulcerative colitis who require colectomy. There are special issues related to male gender. We performed systemic literature review on the topic, incorporating the experience in our specialized Center for Ileal Pouch Disorders, and provide recommendations for the identification and management for the gender-specific issues in male patients with ileal pouches. Chronic pouchitis, particularly ischemic pouchitis, anastomotic leak, and presacral sinus are more common in male patients than their female counterparts. Sexual dysfunction can occur after pouch surgery, particularly in those with pouch failure. Diagnosis and management of benign and malignant prostate diseases can be challenging due to the altered pelvic anatomy from the surgery. Digital rectal examination for prostate cancer screening is not reliable. Transpouch biopsy of prostate may lead to pouch fistula or abscess. Pelvic radiation therapy may have an adverse impact on the pouch function. In conclusion, sexual dysfunction and enlarged prostate can occur in patients with the ileal pouch. The measurement of serum prostate-specific antigen is a preferred method for the screening of prostate cancer. If biopsy of the prostate is needed, the perineal route is recommended. The risk for pouch dysfunction and the benefit for oncologic survival of pelvic radiation for prostate cancer should be carefully balanced.

Abstract
BACKGROUND There are no published studies comparing pouch configurations and long-term adverse outcomes. AIM To evaluate outcomes of ulcerative colitis (UC) patients undergoing restorative proctocolectomy with S-, J- pouches or continent ileostomy (CI). METHODS We conducted a historical cohort study from the prospectively maintained Pouch Registry. Demographic and clinical variables were evaluated with univariate and multivariable analyses. RESULTS Fourty-five patients with S pouches and 36 with CI (33 K pouches and 3 Barnett continent ileal reservoirs) were compared with 215 J pouches serving as controls (ratio 1:2.5). In multivariable analysis, patients with S pouches were 93% less likely to develop chronic antibiotic-refractory pouchitis (CARP) than subjects with J pouches (odds ratio [OR]=0.07; 95% confidence interval: <0.001, 0.54; p<0.001). However, no significant difference in the frequency of CARP was found between the CI and J pouch groups (OR=0.68; 95% confidence interval: 0.17, 2.00, p=0.40). Patients with S pouches were 8 times more likely (95% confidence interval: 3.7, 17.5; p<0.001) and patients with CI 5.6 had times more likely (95% confidence interval: 2.4, 13.3; p<0.001) to have pouch surgery-related complications than those with J pouches. There was no difference in the rate of CD of the pouch, pouch-associated hospitalization and pouch failure between the S- pouch, CI and J- pouch groups. CONCLUSIONS Patients with J pouches appeared to have a greater risk for chronic pouchitis than those with S-pouches and but had a lower risk for developing pouch surgery-related complications than those with S pouches or CI.

Abstract
Pouchitis is the most common complication among patients with ulcerative colitis who have undergone restorative proctocolectomy with ileal pouch-anal anastomosis. Pouchitis is actually a spectrum of diseases that vary in etiology, pathogenesis, phenotype, and clinical course. Although initial acute episodes typically respond to antibiotic therapy, patients can become dependent on antibiotics or develop refractory disease. Many factors contribute to the course of refractory pouchitis, such as the use of nonsteroidal anti-inflammatory drugs, infection with Clostridium difficile, pouch ischemia, or concurrent immune-mediated disorders. Identification of these secondary factors can help direct therapy.

Abstract
OBJECTIVE This study aims to evaluate the clinical characteristics of patients with postoperative ulcerative colitis developing extremely early-onset pouchitis within 4 weeks of restoration of gastrointestinal continuity. MATERIAL AND METHODS This retrospective study involved 225 consecutive patients from January 2000 to May 2011 who underwent ileal pouch-anal anastomosis for ulcerative colitis with a minimum follow-up of 12 months. Extremely early-onset pouchitis was defined as pouchitis developing within 4 weeks of restoration of gastrointestinal continuity. Patients with pouchitis were divided into extremely early-onset pouchitis and non-extremely early-onset pouchitis groups for comparison. RESULTS Of 212 patients who met the inclusion criteria, 62 had pouchitis (29.2 %). Eight (3.8 %) patients developed extremely early-onset pouchitis. There was a significant difference in the dosage of steroid per month just before colectomy between the two groups (P = 0.039). The modified Pouchitis Disease Activity Index score for patients with extremely early-onset pouchitis was higher than in patients with non-extremely early-onset pouchitis (P = 0.0009). The occurrence of extremely early-onset pouchitis was associated with the development of chronic pouchitis (P = 0.0056). CONCLUSION Extremely early-onset pouchitis may be related to high steroid dosages before colectomy and may be more severe than pouchitis that occurs >4 weeks after restoration of gastrointestinal continuity.

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
Restorative proctocolectomy with ileal-pouch anal anastomosis (RPC) is the operation of choice for ulcerative colitis (UC) patients requiring surgery. It is also used for patients with familial adenomatous polyposis (FAP). Pouchitis accounts for 10% of pouch failures. It is an idiopathic inflammatory condition that may occur in up to 50% of patients after RPC for UC. It is rarely seen in FAP patients after RPC. The etiology of pouchitis remains unclear. An overlap with UC is suggested by the frequency with which pouchitis affects patients with UC compared with FAP patients. There is significant clinical evidence implicating bacteria in the pathogenesis of pouchitis. Studies using culture and molecular methods demonstrate a dysbiosis of the pouch microbiota in pouchitis. Risk factors, genetic associations, and serological markers of pouchitis suggest that the interactions between the host immune responses and the pouch microbiota underlie the etiology of this idiopathic inflammatory condition. Here we present a detailed review of the data focusing on the pouch microbiota and the immune responses that support this hypothesis. We also discuss the contribution of luminal metabolic factors and the epithelial membrane in the etiology of this inflammatory process. The ileoanal pouch offers a unique opportunity to study the inter-relationships between the gut microbiota and host immune responses from before the onset of disease. For this reason the study of pouchitis could serve as a human model that significantly enhances our understanding of inflammatory bowel diseases in general.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis has become the procedure of choice for the majority of patients with ulcerative colitis who require surgical treatment. Pouchitis, the most common long-term complication of the procedure, involves a spectrum of disease processes with heterogeneous risk factors, clinical features, disease courses and prognoses. In addition, clinical symptoms of pouchitis are not specific and often overlap with those of other inflammatory and functional pouch disorders, such as Crohn's disease of the pouch and irritable pouch syndrome. Pouchoscopy and biopsy, along with laboratory and radiographic evaluations, are often required for accurate diagnosis in patients with symptoms indicative of pouchitis. Dysbiosis has been implicated as a triggering factor for pouchitis, and concurrent infection with pathogens, such as Clostridium difficile, might contribute to disease relapse and exacerbation. Antibiotic therapy is the main treatment modality. However, the management of antibiotic-dependent and antibiotic-refractory pouchitis remains challenging. Secondary causes of pouchitis, such as ischaemia, NSAID use, the presence of concurrent primary sclerosing cholangitis and other systemic immune-mediated disorders, should be evaluated and properly managed.

Abstract
Background and Aims Secondary thrombocytosis is a clinical feature of unknown significance. In inflammatory bowel disease (IBD), thrombocytosis is considered a marker of active disease; however, iron deficiency itself may trigger platelet generation. In this study we tested the effect of iron therapy on platelet counts in patients with IBD-associated anemia. Methods Platelet counts were analyzed before and after iron therapy from four prospective clinical trials. Further, changes in hemoglobin, transferrin saturation, ferritin, C-reactive protein, and leukocyte counts, before and after iron therapy were compared. In a subgroup the effect of erythropoietin treatment was tested. The results were confirmed in a large independent cohort (FERGIcor). Results A total of 308 patient records were available for the initial analysis. A dose-depended drop in platelet counts (mean 425 G/L to 320 G/L; p<0.001) was found regardless of the type of iron preparation (iron sulphate, iron sucrose, or ferric carboxymaltose). Concomitant erythropoietin therapy as well as parameters of inflammation (leukocyte counts, C-reactive protein) had no effect on the change in platelet counts. This effect of iron therapy on platelets was confirmed in the FERGIcor study cohort (n=448, mean platelet counts before iron therapy: 383 G/L, after: 310 G/L, p<0.001). Conclusion Iron therapy normalizes elevated platelet counts in patients with IBD-associated anemia. Thus, iron deficiency is an important pathogenetic mechanism of secondary thrombocytosis in IBD.

Abstract
BACKGROUND Inflammatory complications of ileal pouch-anal anastomosis (IPAA), including pouchitis and Crohn's disease (CD) of the pouch, are common in patients with restorative proctocolectomy for ulcerative colitis. It is not clear whether these inflammatory conditions can affect upper GI tract. The aim of the study was to evaluate correlation between duodenal and pouch histology in patients with healthy and diseased pouches. METHODS All IPAA patients who had esophagogastroduodenoscopy with biopsy after colectomy (N = 96) were included. H&E slides of gastric, duodenal, neo-terminal ileum, and pouch body biopsies were blindly re-reviewed by an expert GI pathologist for acute and chronic inflammation. Demographic and clinical variables and pouch outcome were analyzed. RESULTS There was a significant correlation between acute inflammation in the duodenum as measured by neutrophil infiltration score and the presence of chronic pouchitis (kappa coefficient = 0.21, P < 0.05). Intraepithelial lymphocytosis of the duodenum, though uncommon, only occurred in patients with irritable pouch syndrome, chronic pouchitis, or CD of the pouch. Crypt distortion of duodenal epithelium was only seen in patients with inflammatory or structural diseases of the pouch, including acute (18.2%) and chronic (5%) pouchitis, CD of the pouch (14.3%), and surgical complications of the pouch (14.4%). CONCLUSION Histologic evaluation of duodenal biopsy may provide additional information in patients with ileal pouches, as patients with normal histology of the pouch may have an abnormal duodenal histology.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for the majority of patients with medically refractory ulcerative colitis (UC) or UC with dysplasia, or familial adenomatous polyposis. Various forms of pouchitis frequently occur after surgery. In fact, pouchitis is the most frequent long-term complication of IPAA in patients with UC, with a cumulative prevalence of up to 50%. The etiology and pathogenesis of pouchitis are not entirely clear. It is generally believed that the initiation and development of the disease process of pouchitis is associated with dysbiosis of pouch reservoir, as evidenced by a favorable response to antibiotic therapy. However, the majority of the patients do not show identifiable etiopathogenetic or triggering factors, therefore being labeled to have idiopathic pouchitis. In contrast, a subgroup of patients, particularly those with antibiotic-refractory pouchitis, may have obvious triggering factors for disease flare-up and progression and may be considered to have secondary pouchitis. Therefore, pouchitis can be classified on the basis of etiology into idiopathic and secondary causes. Approximately 20-30% of patients who present with chronic pouchitis have secondary identifiable and triggering factors, including cytomegalovirus or Clostridium difficile infection, ischemia, concurrent immune-mediated disorders, radiation, collagen deposition, and use of nonsteroidal anti-inflammatory drugs. Careful evaluation of these secondary causes of pouchitis that may contribute to resistance to antibiotics should be performed before the introduction of next-line medical therapy.

Abstract
BACKGROUND There are inconsistencies regarding the risk factors associated with pouchitis and Crohn's disease of the pouch after ileal pouch-anal anastomosis. The aim of this study was to evaluate the associations between precolectomy routine laboratory tests, including platelet counts, and occurrences of inflammatory pouch disorders. METHODS All eligible patients were included from The Pouchitis Clinic. All patients undergoing ileal pouch-anal anastomosis for ulcerative colitis were included if their preoperative laboratory tests were available. Demographic, clinical, endoscopic, and laboratory tests were evaluated with univariate and multivariate analyses. RESULTS A total of 251 patients were included. Fifty-five patients had acute pouchitis and 29 had chronic pouchitis. Forty-two patients were diagnosed with Crohn's disease of the pouch. In multivariate analysis, elevated platelet count was not associated with chronic pouchitis (odds ratio, 0.91; 95% confidence interval, 0.32-2.59; P = 0.86) or Crohn's disease of the pouch (odds ratio, 0.87; 95% confidence interval, 0.38-1.97, P = 0.73) after adjusting for gender, smoking, extraintestinal manifestations, and pouch duration. Active smoking was associated with Crohn's disease of the pouch (odds ratio, 5.64; 95% confidence interval, 1.98-16.1; P = 0.001). No other laboratory tests, including white blood cell counts, albumin levels, and hemoglobin levels, were associated with the pouch outcomes. The presence of extraintestinal manifestations was associated with acute pouchitis (odds ratio, 1.89; 95% confidence interval, 0.95-1.14; P = 0.05) and chronic pouchitis (odds ratio, 2.6; 95% confidence interval, 1.13-5.87; P = 0.03). CONCLUSION Precolectomy laboratory tests, including platelet counts, did not appear to impact the occurrence of inflammatory pouch disorders after ileal pouch-anal anastomosis.

Abstract
Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with medically refractory ulcerative colitis (UC) or UC-associated dysplasia, and for the majority of patients with familial adenomatous polyposis. Pouchitis and other complications of IPAA are common. There are scant data on laboratory markers for the evaluation and diagnosis of pouch disorders. The presence of immunogenotypic markers such as genetic polymorphisms of interleukin-1 (IL-1) receptor antagonist, NOD2/CARD15, Toll-like receptor, and tumor necrosis factor-alpha has been reported to be associated with pouchitis. Immunophenotypic/serologic markers such as perinuclear antineutrophil cytoplasmic antibody and anti-CBir1 have been investigated as possible markers for predicting and diagnosing pouchitis. Fecal markers including lactoferrin and calprotectin seem to be useful in distinguishing inflammatory from noninflammatory pouch disorders. In our practice, we have encountered a large number of pouch patients with Clostridium difficile infection. Laboratory evaluation provides information on the etiology and pathogenesis of pouchitis, and it also helps practicing clinicians with accurate diagnosis, differential diagnosis, disease stratification, and management of ileal pouch disorders.

Abstract
PURPOSE OF REVIEW One of the significant limitations to the investigation of inflammatory bowel disease (IBD) in humans is the impossibility of studying this condition from the beginning of the disease process to understand the individual contribution of the various microbiological and immunological components to its pathogenesis. Pouchitis can serve as a human model for IBD, as the time of the pouch creation is known, which allows to prospectively study the events that might eventually lead to the development of a form of intestinal inflammation (i.e., pouchitis) that mimics IBD. RECENT FINDINGS A considerable amount of progress has been made in the last few years on the mechanisms underlying the pathogenesis of pouchitis. Recent literature suggests that pouchitis may present a spectrum of disease processes, with a wide range of causes, risk factors, clinical phenotypes, disease courses, and prognoses. Genetic, microbiological, and immunological profiles in pouchitis were evaluated. SUMMARY Ileal pouch and pouchitis represent a valuable human model to study the evolution of bacterial communities and host-bacteria interactions in IBD by sequentially monitoring microbiological and immunological profile before, during, and after pouch construction and before and after development and treatment of pouchitis.

Abstract
OBJECTIVES Autoimmune disorders (ADs) frequently coexist with inflammatory bowel disease. The aim of the study was to determine whether coexisting AD in patients with ileal pouches increases the risk for chronic antibiotic-refractory pouchitis (CARP) and other inflammatory conditions of the pouch. METHODS A total of 622 patients seen in our Pouchitis Clinic were enrolled. We compared the prevalence of adverse outcomes of the pouch (including CARP, Crohn's disease of the pouch, and pouch failure) in patients with or without concurrent AD and assessed the factors for these adverse outcomes. RESULTS There were seven pouch disease categories: normal (N=60), irritable pouch syndrome (N=112), active pouchitis (N=131), CARP (N=67), Crohn's disease (N=131), cuffitis (N=83), surgical complications (N=36), and anismus (N=2). The prevalence of AD in these pouch disease categories was 4.5%, 12.5%, 9.2%, 13.4%, 10.7%, 3.8%, 1.5%, and 0%, respectively. The presence of at least one AD at time of pouch surgery was shown to be associated with a twofold increase in the risk for CARP (hazard ratio=2.29; 95% CI: 1.52, 3.46; P<0.001) and for pouch-associated hospitalization (hazard ratio=2.39; 95% CI: 1.59, 3.58; P<0.001). The presence of AD was not associated with increased risk for irritable pouch syndrome, active pouchitis, Crohn's disease, cuffitis, surgical complications, or pouch failure. Patients with Crohn's disease of the pouch had a 2.42 times higher risk for pouch failure (P=0.042) than these without. Active smoking or a history of smoking was shown to be associated with an increased risk for pouch-associated hospitalization and pouch failure. CONCLUSIONS AD appears to be associated with an increased risk for CARP, and the presence of the association between these AD and pouch disorders may stimulate further research on the link of these organ systems on an immunological basis.

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
BACKGROUND & AIMS The effect of orthotopic liver transplantation (OLT) for primary sclerosing cholangitis (PSC) and post-OLT immunosuppression on the disease course of pouchitis is not clear. The aims of this study were to compare the frequency of chronic antibiotic-refractory pouchitis (CARP) in PSC patients with or without OLT and to assess potential risk factors for CARP in these patients. METHODS Ulcerative colitis patients with PSC and ileal pouch-anal anastomosis (IPAA) with or without OLT identified from our prospectively maintained pouch database were analyzed. CARP was diagnosed based on persistent symptomatic pouchitis after a 4-week single- or dual-antibiotic therapy. RESULTS A total of 63 PSC/IPAA patients were studied, including 19 patients with OLT and 44 patients without OLT. Fifty patients (79.4%) had CARP. In both univariable and multivariable analyses (adjusting for OLT status), none of the variables studied was associated significantly with CARP (P > .20). All 7 patients (100%) with IPAA-then-OLT were diagnosed as having CARP, of whom 4 developed CARP before OLT, which persisted after OLT, and 3 had CARP after OLT. Of 12 patients with OLT-then-IPAA, 7 (58.3%) developed CARP. The frequency of CARP in OLT-then-IPAA was statistically significantly lower than that in IPAA-then-OLT (58.3% vs 100%; P = .047). CONCLUSIONS CARP is common in patients with ulcerative colitis and PSC. OLT in these patients may not affect the frequency of CARP in general and appears not to alter the disease course of pre-existing CARP. However, in a subset of patients, OLT might reduce the risk for the development of de novo CARP.

Abstract
NSAID use has been shown to exacerbate disease activity of inflammatory bowel disease. The detrimental effect of NSAIDs on the ileal pouch has not been characterized. To study the effect of withdrawal of NSAID use on ileal pouch disorders. The study consisted of a cohort of 17 symptomatic patients seen in the Pouchitis Clinic who had ulcerative colitis and ileal pouch-anal anastomosis with chronic (>6 months) daily use of NSAIDs. The patients were treated by withdrawing NSAID use. The Pouchitis Disease Activity Index (PDAI) consisting of symptom, endoscopy and histology scores, and Cleveland Global Quality of Life, Irritable Bowel Disease Quality of Life, and Short Inflammatory Bowel Disease Questionnaire scores were measured before and after a 4-week intervention. The cohort consisted of 11 patients with chronic refractory pouchitis (65%), 2 with acute pouchitis (12%), 1 with cuffitis (6%), 1 with cuffitis and chronic refractory pouchitis (6%), and 2 with irritable pouch syndrome (12%). The withdrawal of NSAID use alone resulted in a significant reduction in the mean PDAI scores of -3.6 +/- -3.0 (p<0.02) and a significant improvement in mean quality-of-life scores (p<0.05). Patients with pouch disorders who regularly used NSAIDs appeared to benefit from the complete cessation of such agents, suggesting an association between NSAID use and pouch disorders.

Abstract
BACKGROUND & AIMS Although acute pouchitis (AP) after ileal pouch-anal anastomosis (IPAA) for UC is common and easily treated, chronic pouchitis (CP) remains a difficult management issue. The aim of this study was to identify important clinical risk factors associated with AP or CP. METHODS AP and CP were prospectively assessed, and demographic, disease, and treatment characteristics were tabulated. Univariate and multivariate analyses were performed to evaluate associations between AP or CP and potential risk factors. RESULTS Two hundred IPAA patients were followed for a median of 24 months (range, 3-117 months). Thirty-six patients (18%) developed AP, and 23 patients (12%) developed CP. On univariate analysis, the use of steroids before colectomy and smoking were associated with the development of AP. CP was associated with male gender, smoking, length of follow-up, extraintestinal manifestations, backwash ileitis, and elevated (450x10(9)/L) platelet count. On multivariate analysis, the following risk factors were found to be independently associated with AP: use of steroids before colectomy (odds ratio [OR], 3.7; 95% confidence interval [CI], 1.5-8.9; P = .004) and smoking (OR, 2.3; 95% CI, 1.1-5.3; P = .04). CP was directly associated with extraintestinal manifestations (OR, 3.5; 95% CI, 1.1-11.1; P = .03), elevated platelet count (OR, 3.1; 95% CI, 1.1-8.9; P = .03), and increased length of follow-up (OR, 1.3; 95% CI, 1.1-1.6; P = .002). Smoking reduced the incidence of CP (OR, 0.2; 95% CI, 0.05-0.74; P = .04). CONCLUSIONS Clinical factors associated with AP included use of steroids before colectomy and smoking. Factors directly related to CP were extraintestinal manifestations, elevated platelet count, and length of follow-up after IPAA. Smoking appears to protect against the development of CP.
