Endoscopic treatment of suture line bleeding ulcer caused by nonabsorbable suture material in postvagotomy patients.

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.
