Utility of image-enhanced magnifying endoscopy and traction wire for a successful endoscopic submucosal dissection in early gastric cancer

Characterizing tumor extent in early gastric cancer (EGC) is difficult and magnifying endoscopy with narrow-band imaging (M-NBI) is often necessary [1] [2]. Submucosal dissection of large lesions via endoscopic submucosal dissection (ESD) is a time-consuming task. Here, we report the benefit of the traction wire (ERD-TW35; Medtronic, Minneapolis, Minnesota, USA) [3] [4] [5] as a unique technique for ESD.
