 A technique for endoscopic submucosal dissection has been developed to cut mucosal cancer with an adequate margin, even when the cancer is larger than that stipulated by conventional indications. It also enable the resection of even depressive lesions with ulcer scar in the submucosal layer. In order to extend the indication for endoscopic mucosetomy, we investigated 1,407 cases of differentiated-type early gastric cancer less than 5 cm in diameter which were resected surgically between 1980 and 2000. The conventional indication was extended in 32.9 % of those lesions. If the 2~5 cm sized lesions without submucosal elements are added to the indication, the ratio increases by 11.5 %. If mucosal depressive lesions less than 3 cm with ulcers restricted to the submucosal layer are added, it increases by 13.2 %. X-ray examination would be useful to exclude superficial-type gastric cancer from the lesions of the patients referred for endoscopic submucosal dissection and to recognize in the lesions the depth of depressive-type early cancer with ulceration.
