Objective:To explore the risk factors of postsurgical gastroparalysis syndrome(PGS) after subtotal gastrectomy.Methods:310 cases of subtotal gastrectomy were retrospectively analyzed,the cases of PGS were observational group,and the non-PGS were control group,mono-factor analysis and Logistic regression analysis were performed toward the personal factors,surgical factors and postsurgical factors.Results:15 out of 310 cases were PGS(4.84%),the age, preoperative pyloric obstruction,postoperative hyperglycemia,perioperative hypoproteinemia,Bil roth I gastrectomy,long operation time,the amount of intraoperative bleeding,unhealthy psychology,using patient control analgesia,abdominal infection,postoperatively intestinal nutrition late were associated with the PGS by the mono-factor analysis(p<0.05).the results derived from the logistic regression analysis toward the independent risk factor pointed that the top four factors were arranged in according to the value of OR,preoperative pyloric obstruction,perioperative hypoproteinemia,Bil roth I gastrectomy,unhealthy psychology.Conclusions:the incidence of PGS were derived from many factors,treat pyloric obstruction properly,Bil roth I gastrectomy,shorten the operation time,control glycemia,improve the serum albumin,and strong the psychological support can prevent and reduce PGS.
