 We have treated 100 patients with 104 lesions of early gastric cancer by endoscopic resection during the past 6 years.

 The indication for endoscopic resection is limited by the nature of the lesion. That is, (1) macroscopical type and size; type Ⅱa not more than 2 cm in size, or nonulcerative type Ⅱc not more than 1 cm in size, (2) histological type; a differentiated adenocarcinoma, (3) depth; without large amounts of submucosal infiltration.

 Statistically, in these early gastric cancers, the incidence of lymph node metastasis is very rare (less than 1%).

 The resection procedure is as follows: Put pin-point marks around the lesion and pull it up with grasping forceps. After strangling it with a snare wire, apply local injection (about 5 ml of 50% glucose) to prevent bleeding. Then cut it off with high frequency current.

 No complications are experienced when using this method.

 Remnant rate was 11%. Residual cancerous lesions were found on the gastric angle, on the lesser curvature of the body and the antrum. These remnant cancers were treated by microwave coagulation and, upon biopsy, showed negative for cancer. Gastrectomy was performed on 3 patients with massive submucosal invasion in the resected specimens. There were no deaths caused by gastric cancer.
