Between 1974 and 1992, at the Department of Diagnostic and Surgical Endoscopy of Istituto Nazionale Tumori, in Milan, 27 patients with resected stomach and suffering from epithelial polyps of the gastric stump (10 lesions) and/or anastomosis (25 lesions), were endoscopically treated using electroresection (13 cases), electrocoagulation (2 cases), combined methods (electroresection plus Nd:YAG photocoagulation) (1 case) and biopsy forceps (19 cases). Complications occurred in 4 cases and consisted of hemorrhage. Seven patients developed 15 recurrences. Endoscopic treatment of polyps in patients with resected stomach is a safe and effective treatment, considering the low rate of complication.
