To explore the effect of Uncut Roux-en-Y anastomosis, Roux-en-Y anastomosis and Billroth-II anastomosis in the reconstruction of digestive tract in laparoscopic radical distal gastrectomy.

94 patients treated with complete laparoscopic radical gastrectomy from January 2016 to January 2019 were retrospectively analyzed, according to different digestive tract reconstruction methods they were divided into three groups. Among them, 28 patients in group A treated with Uncut Roux-en-Y anastomosis, 36 patients in group B treated with Roux-en-Y anastomosis, and 30 patients in group C treated with Billroth-II anastomosis. SPSS20.0 statistical software was used for data analysis. Perioperative indicators and other measurements were expressed by (±s). One-way ANOVA was used to compare the two groups by t test. Postoperative complications and other counting data were compared by χ² test.

The reduction of surgical anastomosis time and Roux-en-Y stasis syndrome (RSS) in group A was significantly better than those in group B (P<0.05). The intraoperative blood loss and anal recovery time were significantly lower than those in group B and Group C (P<0.05); the reducing reflux gastritis and bile reflux in group A and group B were significantly better than group C (P<0.05); There were no significant differences in the three groups in operative time, recovery time, postoperative hospital stay, anastomotic leakage. ulcer, stenosis, hemorrhage and reflux esophagitis (P>0.05).

Uncut Roux-en-Y anastomosis is simple, safe and feasible, and reduces postoperative complications in gastric cancer radical surgery. It is effective in improving postoperative quality of life and is worthy of clinical promotion.
