Abstract: Objective To evaluate the clinical effect of non-dissected Roux-en-Y anastomosis on laparoscopic radical gastrectomy for distal gastric cancer and digestive tract reconstruction. Methods A total of 80 patients with gastric cancer who underwent laparoscopic radical gastrectomy from January 2014 to December 2018 were divided into non-dissected Roux-en-Y anastomosis group (observation group, 40 cases) and Billroth II anastomosis group (control group, 40 cases) according to digestive tract reconstruction methods. The surgical indicators, postoperative exsufflation time, complication rate, and hospitalization stay were compared between the two groups. Results The intraoperative bleeding amount and operation duration of the observation group were more than those of the control group (P<0.01), but no significant differences in complication rate and hospitalization time were observed between the two groups. Conclusion Non-dissected Roux-en-Y anastomosis is effective and safe in laparoscopic radical gastrectomy for distal gastric cancer and digestive tract reconstruction.
