In order to cure early gastric cancer and gastric adenoma, Endoscopic Mucosal Resection (E. M. R.) was performed, and the indication of E. M. R to them was examined. In thirty-five out of sixty-nine lesions (50.7%), negative focal residuum was observed, and in thirty out of thirty-five lesions there have no remnants and recurrence observed up to the present. The progress of these lesions is still now being observed. It is significant that the rate of negative focal residuum in antrum and prepylorus was much higher than that in other portions of the stomach. In every portion of the stomach which is more than 10mm in size, a lot of remnant lesions were observed. E. M. R. for early gastric cancer is best indicated for the lesion which is located in the antrum including prepylorus, well-differentiated in histological type, localized in the mucosal layer, no ulcer formining, and size less than 10mm.
