Effect of Simplified Robot (FASTER) Assisted Versus Conventional Endoscopic Submucosal Dissection (ESD) for Colorectal Lesions

This study aims to compare the outcomes of Simplified Robot (FASTER) assisted Endoscopic Submucosal Dissection (ESD) with conventional ESD in the treatment of colorectal lesions. Using a prospective, single-center, randomized controlled design, the investigators will systematically evaluate differences between the two approaches in terms of total procedure time, mucosal dissection time and speed, resection quality (R0 resection rate and en bloc resection rate), incidence of complications (bleeding, perforation, muscularis injury), and the flexibility and clinical feasibility of robotic operation. The clinical significance of this study lies in assessing the value of robotic assistance in colorectal ESD, optimizing intraoperative workflow, reducing complication risks, improving patient outcomes and procedural efficiency, and providing evidence to support individualized therapeutic strategies in clinical practice.This study aims to compare the outcomes of Simplified Robot (FASTER) assisted Endoscopic Submucosal Dissection (ESD) with conventional ESD in the treatment of colorectal lesions.
