Abstract

Abstract: Objective To assess the clinical outcomes of 8-like ring-assisted endoscopic submucosal dissection (ESD) for challenging colorectal cases. Methods In this study, we conducted a retrospective data collection of 42 patients with colorectal adenomas or early-stage cancer who underwent 8-like ring-assisted ESD at Beijing Friendship Hospital from November 2018 to September 2021. The baseline data, including age, gender, lesion morphology, and lesion size, were collected. Safety and efficacy were evaluated by analyzing operative time, enbloc resection rate, complete resection rate, and complications. Results The mean procedure time of ESD was （60.26±37.77） min, en bloc resection rate was 98% (41/42) and complete resection rate was 93% (39/42). Histopathologic examinations showed that there were 11 low-grade intraepithelial neoplasia cases, 23 high-grade intraepithelial neoplasia cases, and 8 submucosal （SM)adenocarcinoma cases. For the complication, perforation occurred in 3 cases and delayed bleeding occurred in 0 cases. All complications were successfully resolved under endoscopy management. No recurrences, anal stenosis and defecation difficulties events were observed during the follow-up period in all patients. Conclusion The 8-like ring assisted ESD is safe and feasible as a minimal invasive way for treatment.

Key words: 8-like ring, endoscopic submucosal dissection, safety, feasibility, complete resection
