Full-thickness Laparo-endoscopic Excision vs Laparoscopic Colectomy for Colonic Tumors

Adenoma - carcinoma is a classic pathway of carcinogenesis. On this basis, timely removal of colon adenomas is a prophylactic measure to prevent colon cancer. The standard treatment of colorectal adenomas is endoscopic mucosal resection or submucosal dissection (ESD). In 10 - 15% of cases the ESD is impossible, due to the size of the tumor, inconvenient localisation in the area of the diverticulum or appendix, the presence of fibrosis in the submucosal layer (Currie AC framework IDEAL // Colorectal Disease. 2019. No. 9 (21). P. 1004-1016.), (Suzuki S. Short-term results of laparoscopic endoscopic cooperative surgery of colorectal tumors (LECS-CR) in cases of endoscopically inoperable colorectal tumors // Surgery today . 2019. No. 12 (49). S. 1051-1057.). In that cases the segmental colectomy is justified. An alternative to colectomy is a hybrid laparo-endoscopic surgery, which reduce postoperative hospital stay, incidence of complications and provide a comparable level of radicality (Lee SW, Garrett KA, Milsom JW Combined endoscopic and laparoscopic surgery (CELS) // Seminars on surgery of the colon and rectum. 2017. No. 1 (28). S. 24-29). Thus, the planned study will contribute to the introduction into practice of an alternative method of management with tumors of the colon without signs of invasive growth when the endoscopically removal is impossible.
