Abstract
Endoscopic polypectomy using high frequency current was performed for 281 of 345 [human] gastric polyps (230 cases) while the remaining 64 small polyps were cauterized. Histopathologic examinations carried out in 274 of the 281 polypectomized polyps confirmed gastritis polyposa in 41 lesions, hyperplastic polyps in 216 including 3 cases of neoplasm, atypical epithelium in 4, submucosal tumor in 2 and polypoid cancer in 1. This procedure of endoscopic polypectomy enables histologic examination of a polyp as a whole and allows a highly risk-free endoscopic treatment of polyps. In the currently observed 216 hyperplastic polyps three (1.4%) were found to have neoplastic changes.
