An elastic traction device for facilitating endoscopic submucosal dissection of a submucosal tumor at the cardia

A common challenge encountered during endoscopic submucosal dissection (ESD) is the lack of traction required to achieve an adequate submucosal view of the dissection area and to avoid mucosal and muscle layer injury, perforation, and bleeding [1] [2]. It is even more challenging to perform ESD for tumors located at the cardia of the stomach. Herein, we report a case in which an elastic traction device (Micro-tech, Nanjing, China), consisting of a rotatable tissue clip and an elastic band in the shape of a figure 8 attached to the arm of the clip, was used to improve the intraoperative view and facilitate submucosal tumor (SMT) resection at the cardia. We call this device an "8-shaped band" ([Fig. 1]).
