Note (General): Background/aim: Colorectal endoscopic 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 incidents and muscle injuries in the PRM-group. There were no significant differences in en bloc or R0 resection rates between the groups.
Conclusion: PRM may be a safe, useful, and cost-effective technique for non-experts learning to perform colorectal ESD.
