Background: We developed the "Thin silicone loop band (TSLB) ", an endoscopic submucosal dissection (ESD) traction device made of thin elastic silicone molded into a 10-mm-diameter ring. The TSLB can be attached to an EZ clip and passed through the working channel of an endoscope. Aim: To examine the efficacy of TSLB. Methods: Two endoscopists performed ESD with a needle knife for a 20-mm-diameter virtual lesion with an ESD training model. Twelve lesions treated by conventional ESD (group C, n=6) and ESD with TSLB (group T, n=6) were evaluated for submucosal dissection speed. Results: Mean submucosal dissection speed was 50.1±23.3 mm2/min in group C and 82.2±43.1 mm2/min in group T. TSLB traction was successful in all lesions. Discussion: TSLB may be a simple and useful ESD traction device that improves submucosal dissection speed.
