“…Классическая эндоскопическая резекция слизистой оболочки (endoscopic mucosal resection, EMR) -это простой и эффективный метод, широко используемый во всем мире при лечении больных с эпителиальными новообразованиями толстой кишки [1]. Однако при удалении опухолей размером более 20 мм методом EMR частота резекции единым блоком прогрессивно снижается, нередко по причине фрагментации опухоли, которая, в конечном счете, негативно отражается на частоте локальных рецидивов [2,3].…”

OBJECTIVE: to compare the immediate and long-term results of endoscopic mucosal resection with a circular incision (C-EMR) and endoscopic submucosal dissection (ESD) in the treatment of patients with large benign epithelial neoplasms of the colon.PATIENTS AND METHODS: a prospective randomized comparative study was conducted from November 2020 to July 2022, included 103 patients with benign epithelial neoplasms of the colon ranging in size from 20 to 30 mm. The C-EMR method was used in 52, ESD - 51 patients.RESULTS: the removal of the tumor by the C-EMR method required statistically significantly less time, compared with the ESD method – 30 and 60 minutes, respectively (p<0.001). Intra- and postoperative complications occurred in 13(23.7%) patients in the C-EMR group and in 12(23.5%) patients in the ESD group. The most frequently reported complication was postcoagulation syndrome in the main and control groups – in 9(17.3%) and 11(21.6%) cases, respectively. It was found that the difficult location of the tumor (OR=18.3; p=0.01) and intraoperative complications (OR =37.5; p=0.04) are independent conversion factors of endoscopic intervention. The frequency of tumor removal in a en bloc and achievement of negative resection margins (R0) in the main and control groups did not significantly differ – 47(90.4%) and 49(96.1%) (p=0.4) and 40(76.9%) and 45(88.2%) (p=0.2), respectively.CONCLUSION: endoscopic mucosal resection with a circumferential incision is an effective and safe operation comparable to endoscopic submucosal dissection, and can be the method of choice for benign epithelial neoplasms of the colon with sizes from 20 to 30 mm. In addition, the duration of the operation using the C-EMR method is two times less than using ESD.

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.

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.
