Comparison of clinical effect of functional end-to-end anastomosis and Overlap in radical resection of left heminoses colon cancer.

Clinical data of 78 patients who undergo radical NOSES left half colon cancer from January 2016 to January 2021 are retrospectively analyzed，and divided into two groups according to different ways of intraoperative digestive tract reconstruction. 38 cases of Overlap are included in Overlap group，and 40 cases of FEEA are included in FEEA group. SPSS 22.0 software was used to analyze clinical data. Postoperative complications and other statistical data were represented by［n（%）］. χ² test was used for comparison between groups. Measurement data such as perioperative indexes and postoperative serum nutritional indexes were represented by（

All patients in both groups successfully completed radical NOSES left colon cancer. Operation time and anastomosis time in Overlap group were significantly longer than those in FEEA group；first postoperative exhaust time，hospital stay and hospital cost were significantly better than those in FEEA group（P<0.05）. There was no significant difference in serum nutritional indexes between 2 groups before and 7 days after surgery（P>0.05）. Serum albumin（ALB），hemoglobin（Hb）and total serum protein（TP）in 3 months after operation of Overlap group were significantly higher than those in FEEA group（P<0.05）. There was no significant difference in the total incidence of postoperative complications between 2 groups（P>0.05）.

NOSES left hemipelagic colon cancer Overlap can promote postoperative intestinal function recovery，improve long-term nutritional status，and is of great significance for promoting postoperative rehabilitation and reducing hospitalization costs.
