The Endoscopic resection of gastric tumors following local injections of hypertonic saline‐epinephrine solution (ERHSE) was performed on 72 lesions (69 patients) of gastric tumors at Yoyogi Hospital etc. from March, 1983, to December, 1989. These included 40 cases of adenoma, 31 cases of carcinoma, and one carcinoid tumor. The average length of the major axis of the endoscopically resected tumors was 12 ± 9 mm. The curative rate at the first attempt was 94% (64 of 68 lesions). The curative rate of the final procedure was 99% (67 of 68 lesions). This excluded 4 lesions in 3 patients in whom a follow‐up examination was not possible. There was no relationship found between the final cure rate and the form and location of the lesions. Fifty four lesions were resected with one session of snare cautery; the average length of their major axis was 9 ± 6mm. The resection of 18 lesions was done piecemeal, and the average length of their major axis was 20 ± 10mm. A statistical significance was noted between the size of the lesions which could be resected with one session of snare cautery and those treated by the piecemeal method, but no difference was noted in the location of lesions for the two groups. The indication for ERHSE was assessed in accordance with the cases that resulted in piecemeal resection, those in which the first ERHSE left residual tumor tissues, and those with perforation. ERHSE could be performed with difficulty on lesions which were (1) on the sharply bending gasric wall, (2) observed only tangentially, (3) inadequately observed. These lesions were situated on the gastric fornix, cardia, and their vicinities, the gastric angulus, posterior wall and greater curvature of the gastric body, and anterior wall and lesser curvature of the middle to the upper gastric body.
