Endoscopic submucosal tunnel dissection with an elastic traction device for a circumferential superficial esophageal neoplasm.

Abstract

Endoscopic submucosal dissection (ESD) is an established treatment for superficial esophageal squamous cell neoplasms (SESCNs) [1] [2]. However, it is time-consuming and challenging for large SESCNs, especially circumferential lesions. Endoscopic submucosal tunnel dissection (ESTD) has been reported as an effective technique for circumferential SESCNs [3] [4]. Herein, we report a case of traction-assisted ESTD using a novel elastic traction device (Micro-Tech, Nanjing, China), consisting of a rotatable soft-tissue clip and an elastic double ring attached to the clip arm ([Fig. 1]).
