A study of traction endoscopic submucosal dissection using a unique traction device with a ring and a clip with an obtuse tip.

Appropriate use of traction devices is important in Endoscopic Submucosal Dissection (ESD). The Sure-Clip Traction Band (Microtec: "traction band") is a disposable clip with a series of three small silicone rings, which can be used as a traction device by inserting the clip through two holes. The SB clip long with a 125-degree tip claw angle (SB Kawasumi: hereafter referred to as SB clip) has an obtuse angle tip, can be re-gripped and is considered to cause less damage to the digestive tract wall when withdrawn after clipping. We performed traction ESD using a traction band and SB clip. These were used for gastric ESD in 4 cases and colorectal ESD in 3 cases.
