Endoscopic treatment for pill bezoars after continent ileostomy.

Difficulty intubation is the most common long-term complication after continent ileostomy, which can be associated with nipple valve slippage, parastomal hernia, stenosis. Diagnosis and management of a patient with nipple valve stricture and partial bowel obstruction associated with dietary supplement retention in the pouch reservoir is described. A 50-year-old female patient with ulcerative colitis and a 15-year history of continent ileostomy after total proctocolectomy reported 5-week symptoms of abdominal pain and difficulty in intubating the pouch. Pill bezoar composed of dietary supplement was found in diagnostic pouch endoscopy. Therapeutic pouch endoscopy was performed with balloon dilation of a nipple valve stenosis and retrieval of 224 dietary supplement tablets. Pill bezoar in the pouch is rare. However, patients with continent ileostomy should be advised to avoid taking hard-to-dissolve foods and medications.
