AIM: to assess the early results in patients with benign epithelial colorectal neoplasms which underwent endoscopic mucosal resection with a circumferential incision (C-EMR).PATIENTS AND METHODS: a prospective randomized trial included 50 patients who underwent endoscopic removal of benign epithelial colorectal neoplasms sized 20–30 mm (November 2020 — January 2022). The main group included 26 patients which underwent C-EMR. The control group included 24 patients which underwent endoscopic submucosal dissection (ESD).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 than in the ESD group — 30 vs 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%) procedures in the control group were converted to the C-EMR procedure.CONCLUSION: endoscopic mucosal resection with a circumferential incision is an effective and safe method for removing benign epithelial neoplasms sized 20–30 mm, as well as submucosal dissection. The removal of the tumor by the C-EMR method reduces operative time by half compared with ESD method.
Aim: to evaluate the early results of endoscopic submucosal tunnel dissection (ESTD for large benign colon neo-plasms. Patients and methods: a prospective non-randomized comparative study included 100 patients with large benignepithelial colon neoplasms (more than 3 cm in diameter). The main group included 50 patients who underwentendoscopic submucosal tunnel dissection. The control group included 50 patients who underwent traditional endo-scopic submucosal dissection (ESD). Results: Four (4 %) patients (1 in the main and 3 in the control group) were excluded from the study due to theconversion of endoscopic procedure. The incidence en bloc removal of neoplasms and the negative resection margins were significantly higher in the main group than in the control one — 98 % and 87.2 % (p = 0.04) and 89.8 % and 70.2 %, respectively (p = 0.01). Conclusion: ESTD for large benign epithelial colon neoplasms shows better radicalness in comparison with endo-scopic submucosal dissection.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
