5. Conclusion
colorectal ESD, colorectal epithelial neoplasia
This prospective randomized clinical trial at 4 medical institutions has been designed to compare the efficacy and safety of colorectal ESD using the S-O clip with conventional ESD for colorectal epithelial neoplasia. ESD using the S-O clip may shorten procedure time, reduce the incidence of AEs, and standardize procedure. This study should resolve the clinical questions of whether ESD using the S-O clip is safer and more effective than conventional ESD for colorectal epithelial neoplasia.
