The first experience of use of endoscopic mucosal resection with a circumferential incision in the removal of colon neoplasms
Abstract
OBJECTIVE: to study the immediate results of the treatment of patients with benign epithelial neoplasms of the colon by endoscopic mucosal resection with a circular incision (C-EMR).
PATIENTS AND METHODS: from November 2020 to January 2022, a prospective randomized comparative study was recruted 50 patients who underwent endoscopic removal of benign epithelial neoplasms of the colon with sizes from 20 to 30 mm. In the main group the endoscopic resection of the mucous with a circular incision technique was used (26 patients). The neoplasms of the colon in the control group were removed by endoscopic dissection in the submucosal layer (ESD) – 24 patients.
RESULTS: postoperative complications developed in the C-EMR group in 5 (19.2%), and in the ESD group - in 7 (29.2%) cases (p=0.51). The operative time in the C-EMR group was significantly less comparative with the ESD group – 30 and 60 min., respectively (p<0.001). In all cases in both groups, tumors were removed en bloc. There R0 resection were performed in 22 (84.6%) and in 23 (95.8%) cases in the main and control groups, respectively (p=0.3). Two (8.3%) operation in the control group were converted to the C-EMR procedure.
CONCLUSION: endoscopic resection of the mucosa with a circular incision is an effective and safe method for removing benign epithelial neoplasms ranging in size from 20 to 30 mm, as well as submucosal dissection. The removal of the tumor by the C-EMR method requires two times less time than the ESD method.
