Endoscopic submucosal dissection of appendiceal lesions by using a novel adjustable traction device: A-TRACT-2

Post written by Louis-Jean Masgnaux, MR, from the Gastroenterology and Endoscopy Unit, Edouard Herriot Hospital, Hospices Civils de Lyon, Lyon, France.


We describe the use of an adjustable endoscopic traction system, the A-TRACT-2, a handmade device that can be tightened during the procedure to increase the traction tension and greatly assist the operator in difficult cases such as the 2 appendiceal lesions described in this video article.

Appendiceal lesions are a great technical challenge, even for experienced operators. Endoscopic submucosal dissection (ESD) is constantly evolving to provide easier and safer ways to conduct the procedure. We believe that adaptive traction can be a part of the solution to treat even the toughest lesions.

We think that, ultimately, every large superficial lesion with a risk of neoplasia could and should be treated with ESD. Adaptive traction devices, which provide easier access to the dissection plane and thus safer and faster ESD, could be a part of the solution to reach this objective.

The device in its industrialized form will be available for use in the United States in late 2023. Feel free to contact me for more information about the case or the device.
