A novel strategy facilitating endoscopic submucosal dissection of proximal colonic lesions: the rubber band and sheath method.

Abstract

A 70-year-old woman was referred to our hospital for the treatment of a laterally spreading tumor in the ascending colon ([Fig. 1]). Endoscopic submucosal dissection (ESD) was performed using a novel strategy with an orthodontic elastic rubber band (Latex Elastics Light 8 mm; Tomy International, Osaka, Japan) and EndoTrac (EndoTrac T type; Top, Tokyo, Japan) ([Fig. 2], [Video 1]) [1]. The latter is a traction device composed of a plastic sheath and a line with an adjustable loop at its tip.
