We present an unusual case of a 35-year-old male patient whom a patency capsule stayed in his gut without breaking. He has a history of Peutz-Jeghers syndrome and multiple abdominal surgeries. Prestudy was performed for abdominal searching, but a patency capsule remained in the colon over 9 days. He displayed neither abdominal nor obstructive symptoms in that period. We collected the patency capsule using colonoscopy after dilating a postoperative stricture at an anastomotic site of the rectum. Clinicians should bear in mind that patency capsules may become retained as distally as the colon in patients with a surgical history of the large intestine.
