<b><i>Background:</i></b> Creation of a J pouch is the gold standard surgical intervention in the treatment of chronic ulcerative colitis (UC). Pouchoscopy prior to ileostomy takedown is commonly performed. We describe the frequency, indication, and findings on pouchoscopy, and determine if pouchoscopy affects rates of complications after takedown. <b><i>Methods:</i></b> All UC or indeterminate inflammatory bowel disease patients with a J pouch were retrospectively evaluated from January 1994 to December 2014. Cases were defined as having routine (asymptomatic) pouchoscopy after pouch creation but before ileostomy takedown. Controls were defined as having no pouchoscopy or pouchoscopy on the same day as that of takedown. <b><i>Results:</i></b> The study included 178 patients (81.5% cases, 18.5% controls). Fifty two percent of pouchoscopies were reported as normal. Common abnormal endoscopy findings included stricture (35%), pouchitis (7%), and cuffitis (0.7%). Length of stay during takedown hospitalization was shorter for cases than controls (3 vs. 5 days; <i>p</i> = 0.001), but neither short- nor long-term complications were statistically different between cases and controls. Abnormalities on pouchoscopy were not predictive for short-term complications (<i>p</i> = 0.73) or long-term complications (<i>p</i> = 0.55). Routine pouchoscopy did not delay takedown surgery in any of the included patients. <b><i>Conclusions:</i></b> Routine pouchoscopy may not be necessary prior to ileostomy takedown; its greatest utility is in patients with suspected pouch complications.
