A novel clip-band traction device to facilitate colorectal endoscopic submucosal dissection and defect closure

Abstract

Endoscopic submucosal dissection (ESD) allows for en bloc resection of large superficial lesions throughout the GI tract.1,2 Adequate visualization of the submucosal dissection plane is critically important for both safety and efficacy in ESD. In traditional surgery, an assistant provides effective countertraction. However, this is not feasible with endoscopic resection, wherein countertraction is naturally absent, aside from the effects of gravity acting on the partially resected lesion.
