Objective: The objective is to analyze the results of endoscopic submucosal dissections (ESDs) of large intestine tumors performed in one clinic. Methods : Data on 207 ESDs in large intestine for 2007–2019 were analyzed. The duration and speed of surgical operation, the number of en block resections and curable resections, and the level of complications and change of results within gain in experience were assessed. Results : According to locations, tumors are divided as follows: right-sided – 48, left-sided – 71, rectal – 88. The average speed of submucosal dissection was 13.5 mm2/min.; the average time taken for dissection of one square centimeter of a tumor was 12.5 min. The conversion to loop assistance was required in 35 cases, conversion to a laparoscopic resection – in two cases. According to criteria of endoscopic radical operations, 170 (82.1%) cases were considered curable. As experience of operations was gaining, despite the increase in number of tumors of right-sided location, the speed of ESDs was significantly increased, and the number of perforations and conversions to loop assistance was not changed. Conclusions : ESD is an effective method of large intestine tumor removal; however, during the training period, a professional should gain an experience in at least 100 operations.
