Comparison of different endoscopic resection techniques for submucosal tumors originating from muscularis propria at the esophagogastric junction

Abstract

Abstract Background To compare the outcomes of submucosal tunneling endoscopic resection (STER) and submucosal excavation (ESE) for the treatment of submucosal tumors (SMTs) arising from the muscularis propria (MP) at the esophagogastric junction (EGJ). Methods A retrospective analysis of patients with SMTs at EGJ who underwent STER and ESE from October 2011 to October 2017 was performed. The outcomes evaluated were operation time, complete resection rate, adverse events, and tumor recurrence. Results Ninety patients were included in this study. Complete resection rates in the STER group were higher than those of the ESE group (100 vs. 92%, p 15 mm, complete resection rate was higher in the STER group than the ESE group (100% vs. 77.8%, p 15 mm, STER is the preferred choice due to its higher complete resection rate.
