Incidental obstruction, pelvic sepsis, and local problems around the ileostomy are occasional complications after the operation. Before closure, the integrity of the pouch and the anal anastomosis is evaluated by radiographic procedures with water-soluble contrast. Direct evaluation of the anastomosis for patency is also necessary. Frequently it strictures or develops a web across it requiring examination with sedation in the GI lab. Pouchoscopy can also be performed at this time. If no problems exist, the ileostomy is closed within 4 months.
