- W3126202455 abstract "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. Since the first case of DCT-ESD in March 2017, all cases of colonic ESD have been performed using the DCT-ESD strategy in the 3 centers involved in the study. Results Five hundred ninety-nine lesions with a mean size of 53 mm were included in this study, resected by 5 operators in 3 centers. The en bloc, R0, and curative resection rates were 95.7%, 83.5%, and 81.1%, respectively. The adverse event rates were 4.9% for perforation and 4.2% for postprocedure bleeding. Between 2017 and 2019, the rates of R0 and curative resections increased significantly from 74.7% in 2017 to 88.4% in 2019 (P = .003) and from 72.6% in 2017 to 86.3% in 2019 (P = .004), respectively. Procedure duration and speed of resection were 62.4 minutes and 39.4 mm2/minute, respectively. No differences were noted between operators. Conclusion DCT-ESD is a safe and reproducible technique, with results comparable with those of the large Japanese teams with speed of resection twice as high as previously reported studies. The DCT strategy is promising, cheap, and seems to be reproducible. Physicians performing colonic ESD should be aware of this promising tool to improve their results in ESD.
