Abstract
Recently conservative treatment of gastric submucosal tumors is increasing in spite of the absence of definite criteria for histological diagnosis. A new method of endoscopical treatment of gastric submucosal tumors that have submucosographically intraluminal pattern I or II or partly intramural pattern III was developed. For tumors with a maximum diameter less than 5 cm, partial resection was carried out with the use of high-frequency electric currents and for the residual tumor tissue, in vivo tissue solidification was undertaken by local injection of absolute ethanol to induce necrotic exfoliation of the tumor tissue and to prevent hemorrhage.
