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