Endoscopic gastric polypectomy using high frequency current: its significance for total biopsy of gastric polyp.
Endoscopic polypectomy using high frequency current was performed for 281 out of 345 gastric polyps (230 cases), while the remaining 64 small polyps were cauterized. Histopathologic examinations carried out in 274 out 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 has proved to enable histologic examination of a polyp as a whole, and to allow a highly risk-free endoscopic treatment of polyps. In the currently observed 216 hyperplastic polyps, 3(1.4%) were found to have neoplastic changes.
