Novel effective and repeatedly available ring-thread counter traction for safer colorectal endoscopic submucosal dissection

Background Although several methods to create an effective counter traction for safer endoscopic submucosal dissection (ESD) have been reported, these methods do not overcome problems regarding delivery and ease of use. This randomized prospective study assessed the usefulness of ring-shaped thread counter traction, which not only allowed the safer colorectal ESD but also the easiest and lower cost counter traction without any special devices.
