Background: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) has become the standard surgical treatment for the majority of patients with inflammatory bowel disease (IBD) who require colectomy. We evaluated the prevalence of pouch-related symptoms among the Crohn's and Colitis Foundation of America Partners cohort and the effect of pouch-related symptoms on Patient-Reported Outcome Measurement Information System measures. Methods: We performed analyses nested in the Crohn's and Colitis Foundation of America Partners cohort. We used bivariate analyses to compare demographics and medication use among patients with ulcerative colitis or indeterminate colitis and pouch-related symptoms and those with IPAA without symptoms. We also compared Patient-Reported Outcome Measurement Information System domains (measured in T-scores) and short IBD questionnaire quality of life scales between symptomatic pouch patients (over the past 6 mo) and those without symptoms. Results: Among 243 patients reporting a history of IPAA, 199 (82%) reported a history of pouch symptoms. Patients with recent pouch symptoms demonstrated higher mean T-scores in pain interference (53.0 versus 45.3; P < 0.001), depression (51.0 versus 46.4; P = 0.002), and fatigue (56.3 versus 47.0; P < 0.001). Symptomatic pouch patients reported lower mean scores in social role satisfaction (47.4 versus 54.6) and short IBD questionnaire (4.8 versus 5.8) (both P < 0.001). These differences were all clinically meaningful. Conclusions: In a large sample of patients with IBD, nearly all patients with IPAA reported a history of pouch symptoms. Patients experiencing symptoms within the 6 months before the survey assessment demonstrated clinically meaningful decrements in patient-reported outcomes in multiple domains of physical and psychosocial functioning
