Introduction

Endoscopic submucosal dissection (ESD) is established as the standard en bloc resection method for superficial esophageal tumor, including leiomyoma [1] [2]. However, it comes with the drawback of significant technical requirements, long procedure times, and potential adverse complications [3]. Because of this, we established a novel double snare resection (DSR) technique to effectively accomplish en bloc resection of a small esophageal leiomyoma ([Video 1]).

Video 1 Double snare resection (DSR) technique for complete removal of an esophageal leiomyoma. The in vitro demonstration of sequential assembly of two snares outer and inner the endoscope respectively. A snare was inserted through single-channel endoscope to precisely capture the tumor and shape it into a “pedicle poly” in the esophagus. Another snare being pre-anchored over the transparent cap’s head was promptly released from the scope to firmly curbed the tumor from its root. As the outer snare being energized, the tumor was fully resected by electrotomy in several seconds. After the specimen inside the inner snare was easily retracted, a clean surgical wound with smooth submucosal layer was displayed.
