title: Endoscopic treatment of suture line bleeding ulcer caused by nonabsorbable suture material in postvagotomy patients.
abstract: Two postvagotomy patients with upper gastrointestinal bleeding, which appeared several months after operation, are reported. Endoscopy showed the pyloroplasty suture line to be ulcerated and bleeding, with a few strands of silk protruding from edematous mucosa. The history of suture line ulceration and the contribution of endoscopy to its diagnosis and treatment are reviewed.
