Abstract

Abstract: Background : For submucosal tumors (SMTs) originating from the muscularis propria (MP) layer of the esophagogastric junction (EGJ), submucosal tunneling endoscopic resection (STER) is now widely used, and it shows promise in overcoming the limitations of endoscopic submucosal dissection.Aims : This study aimed to evaluate the efficacy and safety of the STER technique for treating SMTs of the EGJ originating from the MP layer.Material and methods : From October 2011 to February 2014, 20 patients were enrolled for STER surgery.Results : The patients were categorized into three groups according to the tumor location. The esophagocardiac group had a lower complication rate (0/7) compared with the cardiac group (3/6) and the gastrocardiac group (3/7). The mean operation time in the esophagocardiac (83 ± 24 min) and cardiac (83 ± 55 min) groups was significantly shorter than that of the gastrocardiac group (145 ± 44 min) ( P < 0.05). The en bloc resection rate was 100%, with no severe complications and no recurrence during the follow-up period.Conclusions: The STER technique appears to be a feasible and safe minimally invasive approach for SMTs originating from the MP layer of the EGJ, with satisfying en bloc resection, a short operation time, and low rates of severe complications.
