Double-clip traction for colonic endoscopic submucosal dissection: a multicenter study of 599 consecutive cases (with video).

Background And Aims: Colonic endoscopic submucosal dissection (ESD) is particularly challenging and limited to a few expert centers. We recently conducted a pilot study on improvement of colonic ESD with systematic use of a countertraction device (double-clip traction with rubber band [DCT-ESD]).

Methods: A French prospective multicenter study was conducted between March 2017 and September 2019, including all consecutive cases of naive colonic ESD.
