Comparison of Billroth I, Billroth II, and Roux-en-Y Reconstruction After Totally Laparoscopic Distal Gastrectomy: A Randomized Controlled Study

This study aimed to explore the efficacy of delta-shaped Billroth I anastomosis in totally laparoscopic distal gastrectomy for digestive tract reconstruction, and provide clinical data for determining the most appropriate digestive tract reconstruction method after distal gastrectomy. This was a prospective randomized controlled study. A total of 180 patients were randomly and prospectively selected from Renmin Hospital of Wuhan University by random number table. These patients were randomly divided into three groups: Billroth I group, Billroth II group, and Roux-en-Y (RY) group. There were significant differences in resection margin, blood nutrition, and the number of postoperative complications among these three groups (P < 0.05). Furthermore, the resection margin, blood nutrition status, and immunization of patients in these three groups were determined. Compared to the other groups, the RY group was better in terms of hematologic status, immunological index, and postoperative complications. Delta-shaped Billroth I anastomosis in totally laparoscopic distal gastrectomy for digestive tract reconstruction is simple and easy to perform, and has an advantage in postoperative gastrointestinal function recovery. RY reconstruction is superior to Billroth I and Billroth II in terms of postoperative complications.
