Pocket Creation and Ring-thread Traction Facilitates Colorectal Endoscopic Submucosal Dissection for Non-experts

submucosal dissection (ESD) is a difficult technique. Counter-traction may facilitate the procedure but its efficacy in non-experts remains unclear. We determined the safety and efficacy of pocket creation and ring-thread traction (PRM) for non-expert colorectal ESD. Patients and Methods: We retrospectively compared patients who underwent conventional colorectal ESD (C-group, n=50) or PRM (pocket creation, whole-circumferential cutting, ring-thread traction, submucosal dissection; PRM-group, n=48). All procedures were performed by four non-experts, each with <= 40 experiences of colorectal ESD. Results: Procedural time was significantly shorter in the PRM-group compared with the C-group (p=0.007), with less additional device usage (p<0.001). There also tended to be fewer perforation

Our study compared the safety and efficacy of pocket creation and ring-thread traction (PRM) with conventional colorectal ESD in non-experts. The results showed that PRM group had significantly shorter procedural time and less additional device usage compared to the C-group.
