Claim:
1. A method of treating gastroesophageal reflux disease, comprising: a first step of inserting an endoscope to an esophagastric junction; a second step of determining locations of a mucosal layer or a submucosal layer to be dissected on a stomach and the esophogastric junction; and a third step of dissecting one of the mucosal layer and the submucosal layer of a lesser curvature side of the stomach and the esophagogastric junction that is next to the lesser curvature side of the stomach while a mucosal layer and a submucosal layer on a greater curvature side of the stomach is not dissected so that partial stenosis occurs due to cicatrization only in an area in which one of the mucosal layer and the submucosal layer of the lesser curvature side of the stomach and the esophagogastric junction that is next to the lesser curvature side of the stomach is dissected.
