To explore the clinical features and endosonographic (EUS) features of gastric submucosal tumors, the connection of submucosal tumor features and pathological features are analyzed to increase the awareness of submucosal tumors. This study is based on 237 cases of gastric mucosal lesions
from March 2015 to March 2019. Endoscopic ultrasonography was performed to record the size and origin of the lesions and to make the preliminary qualitative diagnosis of the lesions, where endoscopic resections have 186 cases. According to the actual lesion resection in endoscopic ultrasonography,
the origin level of SMTs and the coincidence rate of endoscopic ultrasonography diagnoses are judged. Therefore, endoscopic ultrasonography has high localization, characterization, and differential diagnosis value for gastric mucosal lesions. Diagnosis of gastric mucosal lesions under endoscopic
ultrasonography is helpful for the choice of endoscopic resection surgical method.
