RESUMO
BACKGROUND: Approximately half the patients with ulcerative colitis who undergo restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) will subsequently have pouchitis, and among those patients, one fifth will have chronic pouchitis. METHODS: We conducted a phase 4, double-blind, randomized trial to evaluate vedolizumab in adult patients in whom chronic pouchitis had developed after undergoing IPAA for ulcerative colitis. Patients were assigned (in a 1:1 ratio) to receive vedolizumab intravenously at a dose of 300 mg or placebo on day 1 and at weeks 2, 6, 14, 22, and 30. All the patients received concomitant ciprofloxacin from weeks 1 to 4. The primary end point was modified Pouchitis Disease Activity Index (mPDAI)-defined remission (an mPDAI score of ≤4 and a reduction from baseline of ≥2 points in the mPDAI total score; scores range from 0 to 12, with higher scores indicating more severe pouchitis) at week 14. The mPDAI is based on clinical symptoms and endoscopic findings. Other efficacy end points included mPDAI-defined remission at week 34, mPDAI-defined response (a reduction from baseline of ≥2 points in the mPDAI score) at weeks 14 and 34, and PDAI-defined remission (a PDAI score of ≤6 and a reduction from baseline of ≥3 points; scores range from 0 to 18, with higher scores indicating more severe pouchitis) at weeks 14 and 34. The PDAI is based on clinical symptoms, endoscopic findings, and histologic findings. RESULTS: Among the 102 patients who underwent randomization, the incidence of mPDAI-defined remission at week 14 was 31% (16 of 51 patients) with vedolizumab and 10% (5 of 51 patients) with placebo (difference, 21 percentage points; 95% confidence interval [CI], 5 to 38; P = 0.01). Differences in favor of vedolizumab over placebo were also seen with respect to mPDAI-defined remission at week 34 (difference, 17 percentage points; 95% CI, 0 to 35), mPDAI-defined response at week 14 (difference, 30 percentage points; 95% CI, 8 to 48) and at week 34 (difference, 22 percentage points; 95% CI, 2 to 40), and PDAI-defined remission at week 14 (difference, 25 percentage points; 95% CI, 8 to 41) and at week 34 (difference, 19 percentage points; 95% CI, 2 to 37). Serious adverse events occurred in 3 of 51 patients (6%) in the vedolizumab group and in 4 of 51 patients (8%) in the placebo group. CONCLUSIONS: Treatment with vedolizumab was more effective than placebo in inducing remission in patients who had chronic pouchitis after undergoing IPAA for ulcerative colitis.

BACKGROUND & AIMS: Pouchitis is the most common complication after restorative proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis. This American Gastroenterological Association (AGA) guideline is intended to support practitioners in the management of pouchitis and inflammatory pouch disorders. METHODS: A multidisciplinary panel of content experts and guideline methodologists used the Grading of Recommendations Assessment, Development and Evaluation framework to prioritize clinical questions, identify patient-centered outcomes, conduct an evidence synthesis, and develop recommendations for the prevention and treatment of pouchitis, Crohn's-like disease of the pouch, and cuffitis. RESULTS: The AGA guideline panel made 9 conditional recommendations. In patients with ulcerative colitis who have undergone ileal pouch-anal anastomosis and experience intermittent symptoms of pouchitis, the AGA suggests using antibiotics for the treatment of pouchitis. In patients who experience recurrent episodes of pouchitis that respond to antibiotics, the AGA suggests using probiotics for the prevention of recurrent pouchitis. In patients who experience recurrent pouchitis that responds to antibiotics but relapses shortly after stopping antibiotics (also known as "chronic antibiotic-dependent pouchitis"), the AGA suggests using chronic antibiotic therapy to prevent recurrent pouchitis; however, in patients who are intolerant to antibiotics or who are concerned about the risks of long-term antibiotic therapy, the AGA suggests using advanced immunosuppressive therapies (eg, biologics and/or oral small molecule drugs) approved for treatment of inflammatory bowel disease. In patients who experience recurrent pouchitis with inadequate response to antibiotics (also known as "chronic antibiotic-refractory pouchitis"), the AGA suggests using advanced immunosuppressive therapies; corticosteroids can also be considered in these patients. In patients who develop symptoms due to Crohn's-like disease of the pouch, the AGA suggests using corticosteroids and advanced immunosuppressive therapies. In patients who experience symptoms due to cuffitis, the AGA suggests using therapies that have been approved for the treatment of ulcerative colitis, starting with topical mesalamine or topical corticosteroids. The panel also proposed key implementation considerations for optimal management of pouchitis and Crohn's-like disease of the pouch and identified several knowledge gaps and areas for future research. CONCLUSIONS: This guideline provides a comprehensive, patient-centered approach to the management of patients with pouchitis and other inflammatory conditions of the pouch.

BACKGROUND: Restorative proctocolectomy with IPAA improves the quality of life in patients with ulcerative colitis by the removal of diseased large bowel and preservation of the natural route of defecation. Although the surgery may improve preexisting extraintestinal manifestations in the joints, skin, and eyes, extraintestinal manifestations, particularly primary sclerosing cholangitis, can persist after colectomy. OBJECTIVES: A systematic review of diagnosis and treatment of liver, joint, skin, and eye manifestations in patients with restorative proctocolectomy and IPAA for ulcerative colitis. DATA SOURCES: PubMed, Google Scholar, and Cochrane database. STUDY SELECTION: Relevant articles on primary sclerosing cholangitis and extraintestinal manifestations in ileal pouches published between January 2001 and July 2023 in English were included on the basis of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION: Diagnosis and treatment of primary sclerosing cholangitis and extraintestinal manifestations in patients with restorative proctocolectomy and IPAA were included. MAIN OUTCOME MEASURES: Association between primary sclerosing cholangitis, extraintestinal manifestations, and inflammatory disorders of the pouch and their management. RESULTS: Primary sclerosing cholangitis and extraintestinal manifestations are associated with pouchitis, particularly chronic pouchitis. Primary sclerosing cholangitis is associated with chronic pouchitis, enteritis, and possible pouch neoplasia. However, the disease severity and course of primary sclerosing cholangitis and pouchitis do not appear to be parallel. Despite the fact that oral vancomycin or budesonide have been used to treat primary sclerosing cholangitis-associated pouchitis, their impact on the disease course of primary sclerosing cholangitis is not known. Biological therapy for chronic inflammatory disorders of the pouch may also be beneficial for the concurrent extraintestinal manifestations of the joints, skin, and eyes. However, studies on the correlation between the severity of inflammatory pouch disorders and the severity of joint, skin, and eye diseases are lacking. LIMITATIONS: This is a qualitative, not quantitative, review of case series and case reports. CONCLUSIONS: Primary sclerosing cholangitis and extraintestinal manifestations of the joints, skin, and eyes appear to be associated with inflammatory disorders of the ileal pouch. Although the treatment of pouchitis does not seem to affect the disease course of primary sclerosing cholangitis, effective therapy of inflammatory pouch disorders, particularly with biologics, likely benefits concurrent disorders of the joints, skin, and eyes.

BACKGROUND: Structural and inflammatory adverse sequelae are common after restorative proctocolectomy and IPAA. On rare occasions, neoplasia can occur in patients with ileal pouches. Pouchoscopy plays a key role in the diagnosis, differential diagnosis, disease monitoring, assessment of treatment response, surveillance, and delivery of therapy. OBJECTIVE: A systematic review of the literature was performed, and principles and techniques of pouchoscopy were described. DATA SOURCES: PubMed, Google Scholar, and Cochrane databases. STUDY SELECTION: Relevant articles on endoscopy in ileal pouches published between January 2000 and May 2023 were included based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION: Diagnostic, surveillance, and therapeutic endoscopy in ileal pouch disorders were included. MAIN OUTCOME MEASURES: Accurate characterization of the ileal pouch in healthy or diseased states. RESULTS: The main anatomic structures of a J- or S-pouch are the stoma closure site, prepouch ileum, inlet, tip of the "J," pouch body, anastomosis, cuff, and anal transition zone. Each anatomic location can be prone to the development of structural, inflammatory, or neoplastic disorders. For example, ulcers and strictures are common at the stoma closure site, inlet, and anastomosis. Leaks are commonly detected at the tip of the "J" and anastomosis. Characterization of the anastomotic distribution of inflammation is critical for the differential diagnosis of subtypes of pouchitis and other inflammatory disorders of the pouch. Neoplastic lesions, albeit rare, mainly occur at the cuff, anal transition zone, or anastomosis. LIMITATIONS: This is a qualitative, not quantitative, review of mainly case series. CONCLUSIONS: Most structural, inflammatory, and neoplastic disorders can be reliably diagnosed with a careful pouchoscopy. The endoscopist and other clinicians taking care of pouch patients should be familiar with the anatomy of the ileal pouch and be able to recognize common abnormalities. See video from symposium.

BACKGROUND: Clinical, nonspecific pouchitis is common after restorative proctocolectomy for ulcerative colitis, but its cause is unknown. A possible lack of protection for the ileal mucosa in its role as a reservoir for colonic-type bacteria may be the missing piece in defining the causes of pouchitis. OBJECTIVE: The study aimed to review the causes of pouchitis and introduce the hypothesis that inadequate mucus protection in the pouch, combined with a predisposition to abnormal inflammation, is the most common cause of nonspecific pouchitis. DATA SOURCES: Review of PubMed and MEDLINE for articles discussing pouchitis and intestinal mucus. STUDY SELECTION: Studies published from 1960 to 2023. The main search terms were "pouchitis," and "intestinal mucus," whereas Boolean operators were used with multiple other terms to refine the search. Duplicates and case reports were excluded. MAIN OUTCOME MEASURES: Current theories about the cause of pouchitis, descriptions of the role of mucus in the physiology of intestinal protection, and evidence of the effects of lack of mucus on mucosal inflammation. RESULTS: The crossreference of "intestinal mucus" with "pouchitis" produced 9 references, none of which discussed the role of mucus in the development of pouchitis. Crossing "intestinal mucus" with "pouch" resulted in 32 articles, combining "pouchitis" with "barrier function" yielded 37 articles, and "pouchitis" with "permeability" yielded only 8 articles. No article discussed the mucus coat as a barrier to bacterial invasion of the epithelium or mentioned inadequate mucus as a factor in pouchitis. However, an ileal pouch produces a colonic environment in the small bowel, and the ileum lacks the mucus protection needed for this sort of environment. This predisposes pouch mucosa to bacterial invasion and chronic microscopic inflammation that may promote clinical pouchitis in patients prone to an autoimmune response. LIMITATIONS: No prior studies address inadequate mucus protection and the origin of proctitis. There is no objective way of measuring the autoimmune tendency in patients with ulcerative colitis. CONCLUSIONS: Studies of intestinal mucus in the ileal pouch and its association with pouchitis are warranted.

BACKGROUND: IPAA is often required for patients with ulcerative colitis or familial adenomatous polyposis after colectomy. This procedure reduces but does not completely eliminate the risk of neoplasia. OBJECTIVE: This study focuses on the histopathology of neoplasia in the ileal pouch, rectal cuff, and anal transition zone. DATA SOURCES: We performed a MEDLINE search for English-language studies published between 1981 and 2022 using the PubMed search engine. The terms "ileal pouch-anal anastomosis," "pouchitis," "pouch dysplasia," "pouch lymphoma," "pouch squamous cell carcinoma," "pouch adenocarcinoma," "pouch neoplasia," "dysplasia of rectal cuff," and "colitis-associated dysplasia" were used. STUDY SELECTION: Human studies of neoplasia occurring in the pouch and para-pouch were selected, and the full text was reviewed. Comparisons were made within and across studies, with key concepts selected for inclusion in this article. CONCLUSIONS: Neoplasia in the pouch is a rare complication in patients with IPAA. Annual endoscopic surveillance is recommended for familial adenomatous polyposis patients and ulcerative colitis patients with a history of prior dysplasia or carcinoma. In familial adenomatous polyposis, dysplastic polyps of the pouch are visible and readily amenable to endoscopic removal; however, glandular dysplasia in the setting of ulcerative colitis may be invisible on endoscopy. Therefore, random biopsies and adequate tissue sampling of the pouch and rectal cuff are recommended in this setting. The histological diagnosis of IBD-associated dysplasia can be challenging and should be confirmed by at least 1 expert GI pathologist. See video from the symposium.

BACKGROUND: Restorative proctocolectomy and IPAA have become the surgical procedure of choice in pediatric patients with medically refractory colitis or familial adenomatous polyposis. OBJECTIVE: This systematic review aims to assess the diagnosis and treatment of pouch disorders in pediatric patients who undergo IPAA. DATA SOURCES: A literature search was performed using MEDLINE, Google Scholar, and Embase for all publications describing outcomes of pediatric IPAA. STUDY SELECTION: Studies between January 1, 2000, and September 7, 2022, published in English were included. Studies were excluded on the basis of title, abstract, and full-length review. INTERVENTIONS: IPAA. MAIN OUTCOME MEASURES: Pouch disorders described include anastomotic leaks, pouch strictures, pouch failure, pouchitis, cuffitis, and de novo Crohn's disease of the pouch. RESULTS: Thirty-three studies were included in this review, all of which were retrospective in nature. The outcomes of 2643 pediatric patients were included in the 33 studies. LIMITATIONS: Management is largely informed by clinical practices in adult patients with scant data on treatment efficacy in children. CONCLUSIONS: The reported incidence of disorders of the pouch in children varies widely and is likely attributable to differences in definitions and follow-up periods across studies. Pouchitis was the most frequently described outcome. The overall rate of pouch failure in children is relatively low, with de novo Crohn's disease of the pouch being the most significant risk factor. Multicenter prospective studies are needed in the pediatric population to accurately identify risk factors, standardize the assessment of pouch complications, and determine effective treatment strategies.

BACKGROUND: Radiographic imaging of the abdomen and pelvis plays an important role in the diagnosis and management of ileal pouch disorders with modalities including CT, MRI, contrasted pouchography, and defecography. OBJECTIVES: To perform a systematic review of the literature and describe applications of cross-sectional imaging, pouchography, defecography, and ultrasonography. DATA SOURCES: PubMed, Google Scholar, and Cochrane database. STUDY SELECTION: Relevant articles on endoscopy in ileal pouches published between January 2003 and June 2023 in English were included on the basis of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. INTERVENTION: Main abdominal and pelvic imaging modalities and their applications in the diagnosis of ileal pouch disorders were included. MAIN OUTCOME MEASURES: Accuracy in characterization of ileal pouch disorders. RESULTS: CT is the test of choice for the evaluation of acute anastomotic leaks, perforation, and abscess(es). MRI of the pelvis is suitable for the assessment of chronic anastomotic leaks and their associated fistulas and sinus tracts, as well as for the penetrating phenotype of Crohn's disease of the pouch. CT enterography and magnetic resonance enterography are useful in assessing intraluminal, intramural, and extraluminal disease processes of the pouch and prepouch ileum. Water-soluble contrast pouchography is particularly useful for evaluating acute or chronic anastomotic leaks and outlines the shape and configuration of the pouch. Defecography is the key modality to evaluate structural and functional pouch inlet and outlet obstructions. Ultrasonography can be performed to assess the pouch in experienced IBD centers. LIMITATIONS: This is a qualitative, not quantitative, review of mainly case series and case reports. CONCLUSIONS: Abdominopelvic imaging, along with clinical and endoscopic evaluation, is imperative for accurately assessing structural, inflammatory, functional, and neoplastic disorders.

Despite the decreased rates in inflammatory bowel disease (IBD) colectomies due to high advances in therapeutic options, a significant number of patients still require proctocolectomy with ileal pouch-anal anastomosis (IPPA) for ulcerative colitis (UC). Pouchitis is the most common complication in these patients, where up to 60% develop one episode of pouchitis in the first two years after UC surgery with IPAA with severe negative impact on their quality of life. Acute cases usually respond well to antibiotics, but 15% of patients will still develop a refractory disease that requires the initiation of advanced immunosuppressive therapies. For chronic idiopathic pouchitis, current recommendations suggest using the same therapeutic options as for IBD in terms of biologics and small molecules. However, the available data are limited regarding the effectiveness of different biologics or small molecules for the management of this condition, and all evidences arise from case series and small studies. Vedolizumab is the only biologic agent that has received approval for the treatment of adult patients with moderately to severely active chronic refractory pouchitis. Despite the fact that IBD treatment is rapidly evolving with the development of novel molecules, the presence of pouchitis represents an exclusion criterion in these trials. Recommendations for the approach of these conditions range from low to very low certainty of evidence, resulting from small randomized controlled trials and case series studies. The current review focuses on the therapeutic management of idiopathic pouchitis.

Pouchitis is the most common long-term complication following ileal pouch-anal anastomosis (IPAA) in patients with ulcerative colitis. Although several agents, including probiotics, steroids, and immunomodulators, have been used, the treatment of pouchitis remains challenging. Owing to the proven efficacy of biological therapy in inflammatory bowel disease, there is now growing evidence suggesting the potential benefits of biological therapy in refractory pouchitis. Here, we report the case of a 64-year-old woman with pouchitis due to ulcerative colitis who was successfully treated with ustekinumab (UST). The patient developed ulcerative pancolitis at the age of 35. Total colectomy and IPAA with J-pouch anastomosis were performed when the patient was 47 years old. Ileotomy closure was performed 6 months later. Postoperatively, the patient developed steroid-dependent pouchitis. Three years later, she developed steroid-induced diabetes. The patient has been taking 3mg of steroid for 20 years;therefore, her lifetime total steroid dose was 21g. The patient had over 20 episodes of bloody diarrhea a day. The last pouchoscopy in 20XX-9 revealed inflammatory stenosis with deep ulcerations of the afferent limb just before the ileoanal pouch junction. In July 20XX, when we took over her treatment, the policy of treatment was to withdraw her from steroids. Pouchoscopy revealed a widened but still tight afferent limb through which the scope could easily pass, and the ileoanal pouch still showed erosive ileitis without ulcers. Thiopurine administration and steroid tapering were initiated. Steroid tapering increased the erythrocyte sedimentation rate (ESR). As ESR increased, her arthritis exacerbated. Six months after the end of steroid administration, the patient consented to UST treatment. On April 20XX+1, the patient received her first 260-mg UST infusion. At this point, she experienced 14-15 episodes of muddy bloody stools. She had no abdominal pain;however, she experienced shoulder pain. Gradually, UST affected both pouchitis and arthritis. UST treatment was continued at 90mg subcutaneously every 12 weeks without abdominal pain recurrence. Eight months after the first UST infusion, nonsteroidal anti-inflammatory drugs were no longer necessary for shoulder pain. Follow-up pouchoscopy performed 14 months after UST optimization revealed a normal afferent limb without ulcerations in either segment. Pouchitis remission was maintained for over 2 years.

OBJECTIVE: To compare the effect of liver transplantation (LT) on ileal pouch-anal anastomosis (IPAA) outcomes in patients with primary sclerosing cholangitis and inflammatory bowel disease (PSC-IBD). BACKGROUND: Patients with PSC-IBD may require both IPAA for colitis and LT for PSC. METHODS: Patients with PSC-IBD from out institutional pouch registry (1985-2022) were divided according to LT status and timing of LT (before and after IPAA) and their outcomes analyzed. RESULTS: A total of 160 patients were included: 112 (70%) nontransplanted at last follow-up; 48 (30%) transplanted, of which 23 (14%) before IPAA and 25 (16%) after. Nontransplanted patients at IPAA had more laparoscopic procedures [37 (46%) vs 8 (18%), P =0.002] and less blood loss (median 250 vs 400 mL, P =0.006). Morbidity and mortality at 90 days were similar. Chronic pouchitis was higher in transplanted compared with nontransplanted patients [32 (67%) vs 51 (45.5%), P =0.03], but nontransplanted patients had a higher rate of chronic antibiotic refractory pouchitis. Overall survival was similar, but nontransplanted patients had more PSC-related deaths (12.5% vs 2%, P =0.002). Pouch survival at 10 years was 90% for nontransplanted patients and 100% for transplanted patients (log-rank P =0.052). Timing of LT had no impact on chronic pouchitis, pouch failure, or overall survival. PSC recurrence was 6% at 10 years. For transplanted patients, graft survival was similar regardless of IPAA timing. CONCLUSIONS: In patients with PSC-IBD and IPAA, LT is linked to an increased pouchitis rate but does not affect overall and pouch survival. Timing of LT does not influence short-term and long-term pouch outcomes.

BACKGROUND & AIMS: Current knowledge regarding the epidemiology of pouchitis is based on highly selected, mostly single-center, patient cohorts. Our objective was to prospectively determine the population-based incidence of pouchitis in patients with ulcerative colitis in the first 2 years after ileal pouch-anal anastomosis and analyze time trends of the incidence of pouchitis. METHODS: Using national registries, we established a population-based cohort of all Danish patients undergoing proctocolectomy with ileal pouch-anal anastomosis for ulcerative colitis between 1996 and 2018. The primary outcome was the development of pouchitis within the first 2 years after surgery, evaluated by time period. We used Kaplan-Meier and Cox proportional hazard modeling to evaluate the time to development of pouchitis. RESULTS: Overall, 1664 patients underwent an ileal pouch-anal anastomosis. The cumulative incidence of pouchitis in the 2 years after ileal pouch-anal anastomosis increased throughout the study period, from 40% in the period from 1996 to 2000 (95% CI, 35%-46%) to 55% in the period from 2015 to 2018 (95% CI, 48%-63%). Patients undergoing surgery between 2015 and 2018 also showed an increased risk of pouchitis compared with the earliest study period (1996-2000) after adjusting for sex, age, and socioeconomic status (hazard ratio, 1.57; 95% CI, 1.20-2.05). CONCLUSIONS: This population-based study showed a 15% absolute and 38% relative increase in the incidence of pouchitis among patients undergoing surgery between 1996 and 2018, with the greatest cumulative incidence of pouchitis shown in the most recent era (2015-2018). The striking increase in the incidence of pouchitis highlights the need for further research into causes and prevention of pouchitis.

INTRODUCTION: The impact of histologic inflammation on subsequent risk of acute pouchitis in patients with ulcerative colitis (UC) has not been robustly examined. METHODS: We examined the association between histologic inflammation in endoscopically normal-appearing ileal pouches in patients with UC with subsequent risk of antibiotic-responsive acute pouchitis. RESULTS: Among 163 study patients, 53% had histologic inflammation in an endoscopically normal-appearing ileal pouch. Histologic inflammation in the pouch was associated with an increased risk of pouchitis (24.1% vs 6.8%, adjusted odds ratio 4.41, 95% confidence interval 1.48-13.20). DISCUSSION: Histologic inflammation in an endoscopically normal pouch was associated with an increased risk of acute pouchitis.

INTRODUCTION: There is minimal evidence regarding the comparative effectiveness of individual antibiotics in the treatment of pouchitis. We sought to evaluate the comparative effectiveness of ciprofloxacin monotherapy, metronidazole monotherapy, and combination therapy (ciprofloxacin and metronidazole) in the treatment of an initial episode of pouchitis after ileal pouch-anal anastomosis for ulcerative colitis (UC). METHODS: We performed a retrospective cohort study in TriNetX, a global federated research network of electronic health records. Primary outcomes were failure of initial antibiotic therapy and the development of recurrent pouchitis in the first 12 months after an initial episode of pouchitis. One-to-one propensity score matching was performed for age, sex, race, primary sclerosing cholangitis, nicotine dependence, obesity, and previous exposure to tumor necrosis factor inhibitors between the cohorts. RESULTS: Among 271 patients who developed pouchitis (mean age at ileal pouch-anal anastomosis 35.8 years, male sex 57%) and were treated with ciprofloxacin, metronidazole, or combination therapy, 190 (70%) developed recurrent pouchitis. After propensity score matching, there was no significant difference in the odds of early relapse or nonresponse with ciprofloxacin compared with metronidazole monotherapy (adjusted odds ratio 0.56, 95% confidence interval 0.23-1.34) or when either monotherapy was compared with combination therapy. There was also no significant difference in odds of recurrent pouchitis when comparing patients treated with ciprofloxacin with metronidazole monotherapy (adjusted odds ratio 0.86, 95% confidence interval 0.40-1.84) or either monotherapy with combination therapy. DISCUSSION: In this retrospective cohort study, we demonstrated no significant difference in the real-world effectiveness of ciprofloxacin, metronidazole, or combination therapy for the initial episode of pouchitis.

Total abdominal proctocolectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC) is associated with substantial complications despite the benefits of managing refractory and/or neoplasia-associated disease. For the purpose of this review, we focused on the diagnosis of some of the most common inflammatory and structural pouch disorders and their respective management. Pouchitis is the most common complication, and it is typically responsive to antibiotics. However, chronic antibiotic refractory pouchitis (CARP) has been increasingly recognized, and biologic therapies have emerged as the mainstay of therapy. Crohn's-like disease of the pouch (CLDP) can affect up to 10% of patients with UC after IPAA. Medical options are similar to CARP therapies, including biologics with immunomodulators. Studies have shown higher efficacy rates of biologics for CLDP when compared with those for CARP. In addition, managing stricturing and fistulizing CLDP is challenging and often requires interventional endoscopy (balloon dilation and/or stricturotomy) and/or surgery. The implementation of standardized diagnostic criteria for inflammatory pouch disorders will help in advancing future therapeutic options. Structural pouch disorders are commonly related to surgical complications after IPAA. We focused on the diagnosis and management of anastomotic leaks, strictures, and floppy pouch complex. Anastomotic leaks and anastomotic strictures occur in approximately 15% and 11% of patients with UC after IPAA, respectively. Further complications from pouch leaks include the development of sinuses, fistulas, and pouch sepsis requiring excision. Novel endoscopic interventions and less invasive surgical procedures have emerged as options for the management of these disorders.

AIM: We aimed to determine whether ulcerative colitis patients with preoperative negative computed tomography or magnetic resonance enterography (CTE/MRE) were less likely to develop Crohn's disease-like pouch complications (CDLPC) and establish risk factors and predictors for developing CDLPC. METHODS: This was a single centre retrospective analysis of patients with ulcerative colitis (UC) and inflammatory bowel disease unclassified (IBDU) who underwent total proctocolectomy with ileal J-pouch between January 2010 and December 2020. The study group comprised patients with negative preoperative CTE/MRE and the control group included patients operated without preoperative CTE/MRE. RESULTS: A total of 131 patients were divided into the negative CTE/MRE study group (76 [58%] patients) and control group (55 [42%] patients). There were no significant differences in incidence rates (21% vs. 23.6%, p = 0.83), time to developing CDLPC from ileostomy closure (22.3 vs. 23.8 months; p = 0.81), pouchitis rates (23.6% vs. 27.2%; p = 0.68), or pouch failure rates (5.2 vs. 7.2; p = 0.71). Multivariate Cox regression analysis showed backwash ileitis (HR 4.1; p = 0.03, CI: 1.1-15.1), severe pouchitis (HR 3.4; p = 0.039, CI: 1.0-10.9), and history of perianal disease (HR 3.4; p = 0.017, CI: 1.4-39.6) were independent predictors for CDLPC. CONCLUSIONS: Negative findings on MRE/CTE prior to J-pouch surgery in ulcerative colitis should be interpreted with caution as it is does not reliably exclude or predict development of CDLPC. These patients should be preoperatively counselled concerning the possibility of developing CDLPC regardless of lack of positive findings on preoperative CTE/MRE. Patients with backwash ileitis with a previous history of perianal disease should be informed of the potentially increased risk of developing such complications.

BACKGROUND: Pouchitis is the most frequent complication following restorative proctocolectomy and ileal pouch anal anastomosis (RP-IPAA) in patients with Ulcerative colitis (UC). Pediatric data on nutritional status during RP-IPAA and in patients with pouchitis are limited. AIMS: We aimed to delineate nutritional changes in children undergoing 2-stage and 3-stage surgeries and to evaluate the association between nutrition and the development of recurrent or chronic pouchitis. METHODS: This single-center retrospective study involved 46 children with UC who underwent a RP-IPAA. Data were collected at each surgical stage and for up to 2-year post-ileostomy takedown. We used Wilcoxon matched-pairs signed-rank test to evaluate the differences in nutritional markers across surgical stages and logistic regression to identify the factors associated with recurrent or chronic pouchitis. RESULTS: Twenty patients (43.5%) developed recurrent or chronic pouchitis. Children who underwent a 3-stage procedure had improvements in albumin, hematocrit, and body mass index (BMI)-for-age Z-scores (p < 0.01) between the first two stages. A positive trend in BMI-for-age Z-scores (p = 0.08) was identified in children with 2-stage procedures. All patients showed sustained nutritional improvement during the follow-up period. Among patients who underwent 3-stage surgeries, BMI worsened by 0.8 standard deviations (SDs) (p = 0.24) between the initial stages in those who developed recurrent or chronic pouchitis and improved by 1.1 SDs (p = 0.04) in those who did not. CONCLUSIONS: Early improvement in BMI-for-age Z-scores following the initial stage was associated with lower rates of recurrent or chronic pouchitis. Larger prospective studies are needed to validate these findings.

INTRODUCTION: Chronic inflammatory conditions of the pouch are common after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC). AIMS: We aimed to investigate the relationship between acute pouchitis within 180 days of the final stage of IPAA surgery (very early pouchitis) and the future development of chronic antibiotic dependent pouchitis (CADP) and Crohn's-like disease of the pouch (CLDP). METHODS: We performed a retrospective cohort study, evaluating patients who underwent proctocolectomy with IPAA between January 1, 2004 and December 31, 2016. Multivariable logistic regression was used to evaluate the relationship between very early pouchitis and the development of CADP and CLDP. RESULTS: Among 626 patients undergoing IPAA for UC, 137 (22%) developed very early pouchitis, 75 (12%) developed CADP, and 59 (9%) developed CLDP in a median follow-up of 5.18 years (interquartile range 0.94-10.8 years). Very early pouchitis was associated with a significant increase in the odds of developing CADP (adjusted odds ratio [aOR3.65, 95% CI 2.19-6.10) as was primary sclerosing cholangitis (aOR 3.97, 95% CI 1.44-11.0). Very early pouchitis was associated with increased odds for developing CLDP (aOR 2.77, 95% CI 1.54-4.98) along with a family history of inflammatory bowel disease (aOR 2.10, 95% CI 1.11-3.96). CONCLUSION: In this cohort, very early pouchitis was associated with an increased risk of developing CADP and CLDP. These findings highlight very early pouchitis as a unique risk factor for chronic inflammatory conditions of the pouch and the need for future studies evaluating potential strategies for secondary prophylaxis strategies in this population.

Pouchitis, the most common long-term complication after colectomy with ileal pouch-anal anastomosis (IPAA) for ulcerative colitis (UC), can lead to increased health care costs and diminished quality of life.1 In this study, we aimed to compare the total costs among patients diagnosed with pouchitis in the first 2 years after an IPAA with those among patients who were not diagnosed with pouchitis, using a large administrative claims database. Additionally, we aimed to investigate the specific drivers of cost among patients with an IPAA during the 2-year study period, including inpatient hospitalizations, emergency department visits, and pharmacy-related costs.
