We have been performed endoscopic polypectomy for polypoid lesions of the stomach and the duodenum, as treatment and complete biopsy. Here, we deal with significance of endoscopic polypectomy for the atypical epithe-lium of the stomach and the duodeum. From Jan. 1973 to Jul. 1975, 134 cases and 226 lesions had been polypectom-ied in our hospital. Out of them, atypical epitheliums were 15 lesions and 14 cases. 8 lesions located at the pyloric antrum, 5 at the body and 2 at the duodenum. 8 lesions were sessile type, and 7 were subpedunculated or peduncu hated type. The maximum sizes of all gastric lesions did not exceed over 20mm. and the maximum sizes of 2 duo-denal lesions were 25mm. and 40mm. respectively. Accord-ing to histological study of biopsied specimens from these lesions, 14 lesions were classified as group III of atypism, 2 were as duodenal adenoma and 1 was as group IV. Ac-cording to histological study of polypectomied lesion, that is, complete biopsy, their degrees of the classification were corrected in some cases, as follows: 2 lesions out of 14 lesions as group III with biopsy were corrected to be eos-inophilic granuloma and grade I to II, each, 2 duodenal lesions changed form grade I to II (Westheus) and one lesion of group IV with biopsy was proven to be a papillo-tubular adenocarcimonatous tissue. As conclusions, by endoscopic polypectomy, 5 lesions out of 17 lesions (29.4%) were corrected their histological findings by biopsy. Therefore, endoscopic polypectomy can be evaluated as both complete biopsy and treatment. No accidents nor complications had been experienced, follow ing polypectomy. According to follow-up study after polypectomy, no recurrence had been experienced.
