Two-time perforation of the ileal J-pouch 6 and 18 years after restorative proctocolectomy and ileal pouch-anal anastomosis for familial adenomatous polyposis: a case report.

The blind end of the J-pouch repeatedly perforated over the years due to recurrent anastomotic stricture. Regular surveillance is, therefore, considered necessary for the release of stricture, maintenance of anastomotic patency, and prevention of ileal J-pouch perforation.
