The Risk Factors Analysis And Retrospective Study Of PGS After The Distal Radical Subtotal Gastrectomy

Objective:To explore and analyze the risk factors of postsurgical gastroparesis syndrome(PGS)after radical distal gastric resection,and in order to reduce the incidence of PGS after radical gastrectomy.Methods:The medical records of patients with distal radical subtotal gastrectomy in general surgery department of Shanxi Provincial People’s Hospital were collected from January2007 to December 2016,and data were collected and analyzed from 335 patients who met the standard.Observation group and control group were categorized according to whether the occurrence of PGS.First of all,the relationship between perioperative related factors and PGS is analyzed by univariate analysis,and then the possible correlation risk factors were analyzed by multivariate logistic regression analysis.Results:A total of 335 cases who underwent the distal radical subtotal gastrectomy were collected and analyzed.Among them,23(6.87%)were diagnosed with PGS.The univariate analysis shows that low body fat index,preoperative hypoproteinemia,perioperative hyperglycemia,preoperative pyloric obstruction,way of anastomosis(Billroth II or Roux-en-Y)and postoperative celiac complications are the risk factors of PGS(P<0.05).Multivariate logistic regression analysis shows that preoperative hypoproteinemia(P=0.012),perioperative hyperglycemia(P=0.009),preoperative pyloricobstruction(P=0.030),way of anastomosis(Billroth II or Roux-en-Y)(P=0.045)and postoperative celiac complications(P=0.036)are the independent risk factors of PGS.Conclusion:PGS is associated with multiple factors,preoperative correction of hypoproteinemia,perioperative control of blood glucose,preoperative pyloric obstruction in patients with complete gastrointestinal decompression and gastric lavage,Billroth I type anastomosis and prevention of abdominal complications,may reduce the incidence of PGS.
