Abstract:
In order to evaluate the use of transendoscopic miniature ultrasonic probe (TEMP) in the diagnosis of gastric submucosal tumor, 18 patients were investigated. The results obtained by TEMP were compared with those of gastroscopy, and endoscopical ultrasonography (EVS). The result showed that among those 18 patients, gastric submucosal leiomyomas, were common and accounted for 88.9％. Most of them were intramural. The diagnostic accuracy of TEMP for the size of tumor and gastric submucosal tumor was 88.9％ and 100％ respectively. Which were much higher than those of gastroscopy (33.3％ and 61.1％ respectively). The sonogrophic characteristics of gastric submucosal tumors in TEMP imaging were related to the nature of the tumors, hut the common manifestations were that all the tumors were hypoechoic under the hyperechoic mucosal layer with clear bell shaped origin, and usually appeared as round or nearly round intragastric eminence. It is concluded that the selective use of TEMP has great value in the diagnosis of gastric submucosal turmor, especially for those lesions which were small and difficult to be detected by EUS.
