Tu1987 THE RETROSPECTIVE COMPARISON BETWEEN SUBMUCOSAL TUNNELING ENDOSCOPIC RESECTION AND ENDOSCOPIC SUBMUCOSAL EXCAVATION FOR MANAGING ESOPHAGEAL SUBMUCOSAL TUMORS

Esophageal submucosal tumors (SMTs) are tissue protuberances covered with normal mucosa, usually without clinical symptoms. In esophagus, leiomyomas and gastrointestinal stromal tumors (GISTs) are two common SMTs and originate from the muscularis propria (MP) layer. The most are benign, but 10.8% leiomyomas might turn into leiomyosarcomas. GISTs are reported to be potentially malignant, especially with the large size or irregular boundary. Submucosal tunneling endoscopic resection (STER) and endoscopic submucosal excavation (ESE) are recently introduced to remove submucosal tumors (SMTs) originating from the muscularis propria (MP) layer.
