Endoscopic ultrasonography in the diagnosis of gastric submucosal tumor

Endoscopic ultrasonography contributed to a correct diagnosis in 24 of 25 patients with gastric submucosal tumor, including 10 extrinsic compressions and 14 intraparietal growths. Leiomyoma and lipoma were easily recognized. In one case, an unusual group of gastric varices was clearly differentiated from a pedunculated polyp prior to polypectomy. In gastric submucosal tumors, endoscopic ultrasonography can greatly reduce the need for aggressive and risky biopsy techniques or exploratory laparotomy.
