目的探讨内镜反转黏膜切除术（REMR）治疗超低位直肠侧向发育型肿瘤患者的临床疗效。方法选取60例超低位直肠侧向发育型肿瘤患者作为研究对象，随机将其分成对照组和研究组，每组30例。对照组行内镜下黏膜切除术，研究组行REMR。比较两组患者切除效果、术中出血量、手术时间和住院时间，以及术后1周的并发症发生率和生命质量。结果研究组患者的完全切除率高于对照组，术中出血量、手术时间和住院时间均少/短于对照组；术后1周，研究组患者的并发症发生率和生活质量量表各维度得分均低于对照组（均P＜0.05）。结论 REMR治疗超低位直肠侧向发育型肿瘤患者，效果显著，值得临床推广使用。

Objective To investigate the clinical efficacy of retroflex endoscopic mucosal resection (REMR) in the treatment of patients with ultra-low rectal laterally spreading tumor. Methods A total of 60 patients with ultra-low rectal laterally spreading tumor were selected as research objects and randomly divided into a control group or a study group, with 30 cases in each group. The control group underwent endoscopic mucosal resection, and the study group underwent REMR. The resection effect, intraoperative blood loss, duration of surgery, and length of hospital stay, as well as the incidence of complications and quality of life 1 week after surgery, were compared between the two groups. Results The complete resection rate of patients in the study group was higher than that of the control group, and the intraoperative blood loss, duration of surgery, and length of hospital stay were less/shorter than those in the control group; 1 week after surgery, the incidence of complications and the quality of life scale scores in each dimension in the study group were lower than those in the control group (all P＜0.05). Conclusion REMR has a significant effect in the treatment of patients with ultra-low rectal laterally spreading tumor, which is worthy of clinical promotion and application.
