Endoscopic submucosal dissection of a quasi-circumferential lesion of the ileo-cecal valve by using a novel adjustable traction device

The technique of submucosal dissection has been expanding rapidly for several years thanks to numerous technical advances. One of these major advances is the improvement of traction strategies, and in particular the appearance of the multi-traction technique. However, several locations remain challenging because of their anatomical particularities, especially lesions of the ileo-cecal valve, which have been the subject of the development of different strategies in recent years [1] [2].
