Abstract:Objective To explore the effects of Billroth I, Billroth II and Roux-en-Y anastomosis on perioperative indexes, gastrointestinal function recovery and complications at 1 year after operation in patients with distal radical gastrectomy.Methods 80 cases of patients with distal radical gastrectomy from February 2015 to February 2018 in Mianyang Central Hospital were divided into group A (n=22, Billroth I anastomosis), group B (n=30, Billroth II anastomosis) AND group C (n=28, Roux-en-Y anastomosis). The perioperative indexes and gastrointestinal recovery were recorded and compared between the two groups. After 1 years of follow-up, Chew-wun Wu special symptom scale was used to evaluate the nutritional status of patients at 6 months after operation, and the incidence rate of complications at 1 years after operation was compared between the two groups.Results The operative time and intraoperative blood loss were positively correlated with the complexity of surgical operations in the three groups. In group A, the operation was the simplest with the shortest operative time and the least intraoperative blood loss. In group C, the operation was the most complicated with the longest operative time and the most intraoperative blood loss (P<0.05). There was no significant difference in postoperative exhaust time, postoperative extubation time, oral intake time and hospital stay between group A and group B (P>0.05). The postoperative exhaust time, postoperative extubation time and oral intake time in group C were all later than those in groups A and B, and the hospital stay was longer than those in group A and group B (P<0.05). The backflow heartburn symptom score in group C were significantly higher than those in group A and group B (P<0.05). The incidence rate of complications such as anastomosis inflammation, anastomotic ulcer, residual gastritis, bile reflux, reflux esophagitis and dumping syndrome was significantly higher in group B (P<0.05). The incidence rates of complications of anastomotic inflammation, anastomotic ulcer, residual gastritis, bile reflux, reflux esophagitis and dumping syndrome in group B were significantly higher than those in group A (P<0.05).Conclusions Billroth I anastomosis after distal radical gastrectomy has simple operations, good recovery of postoperative gastrointestinal function and few complications, and it is more in line with normal human physiological pathways. Billroth II anastomosis has simpler operations but more complications compared with Roux-en-Y anastomosis. Roux-en-Y anastomosis has complicated operations and slow recovery of postoperative gastrointestinal function, but it has good anti-reflux effects and safety, and few complications.
