ObjectiveTo analyze the risk factors for delayed gastric emptying (DGE) after pancreaticoduodenec-tomy (PD). MethodsClinical data of 67 patients who underwent PD in our hospital from September 2012 to June 2014 were retrospectively analyzed. ResultsTwenty-two patients were complicated with DGE of the 67 patients (32.8%) after PD operation. Univariate analysis showed that, diabetes mellitus, the anastomosis methods for stomach and jejunum, and diameter of circular stapler were risk factors for postoperative DGE, the patients who complicated with diabetes mellitus, treated with the traditional Child plus Braun anastomosis method, and treated with 25 mm circular stapler had higher incidence of DGE than patients who didn't complicate with diabetes mellitus, treated with Roux-en-Y anastomosis method, and treated with 28 mm circular stapler (P<0.05). Logistic regression identified 2 variables as independent risk factors which were associated with postoperative DGE, namely, anastomosis methods for stomach and jejunum (OR=0.062,95% CI:0.009-0.407,P=0.004) and diameter of circular stapler (OR=0.135,95% CI:0.034-0.538,P=0.005). The patients who treated with traditional Child plus Braun anastomosis method and 25 mm circular stapler had higher incidence of DGE. ConclusionsThe incidence of DGE after PD is still high. The incidence of DGE could be reduced by using Roux-en-Y method to reconstruct digestive tract and 28 mm circular stapler during PD operation.
