The fifty gastrointestinal polyps, which were removed endoscopically frorn 47 patients at the Seoul National Univeraity. Hospital from January, 1978 to September, 1983, were reviewed with regard to the clinical and pathological features. The observed data are as follows; 1) Fifty polyps were reoved from 10 patients with gastric polyps and 37 patients with colonic polyps. Out of 37 patients 26 were male and 21 female, the sex ratio being 1.2: 1. 2) The gastric polyps were located in the body and antrum and 90 per cent of the colonic polyps were found in the left colon, especially in the rectosigmoid colon. 3) Out of the 10 gastric ployps snared, 8 could be retrivevd, 2 being lost. The histological examination showed that 3 were hyperplastic polyps, 2 gastritis verrucosa, 1 inflammatory polyp and the remaining 1 revealed intramucosel carcinoma with borderline epithelium. 4) Fourty polypectomies were performed in 37 patients with colonic polyps. Histological examination revealed that 24(60%) were adenomatous polyps, 9(22.5%) retention polyp, 4 (10.0%) inflammatory polyp and 3(7. 5%) Peutz-Jegher´s poIyps. Among the adenomatous polys, 4 cases were complicated with focal adenocarcinoma. 5) Except the 2 cases of post-polypectomy bleeding, no other complication was encountered. The one case of hemorrhage after gastric polypectomy was treated with transfusion of 2 pints of whole blood, and the other case after colonic polypectomy required exploratory laparotomy because of inability of bleeding control by electrocoagulation.
