BACKGROUND The influence of bile contamination on the infectious complications of patients undergoing pancreaticoduodenectomy(PD)has not been thoroughly evaluated.AIM To evaluate the effect of preoperative biliary drainage and bile contamination on the outcomes of patients who undergo PD.METHODS The database of 4101 patients who underwent PD was reviewed.Preoperative biliary drainage was performed in 1964 patients(47.9%),and bile contamination was confirmed in 606 patients(14.8%).RESULTS The incidence of postoperative infectious complications was 37.9%in patients with preoperative biliary drainage and 42.4%in patients with biliary contamination,respectively.Patients with extrahepatic bile duct carcinoma,ampulla of Vater carcinoma,and pancreatic carcinoma had a high frequency of preoperative biliary drainage(82.9%,54.6%,and 50.8%)and bile contamination(34.3%,26.2%,and 20.2%).Bile contamination was associated with postoperative pancreatic fistula(POPF)Grade B/C,wound infection,and catheter infection.A multivariate logistic regression analysis revealed that biliary contamination(odds ratio 1.33,P=0.027)was the independent risk factor for POPF Grade B/C.The three most commonly cultured microorganisms from bile(Enterococcus,Klebsiella,and Enterobacter)were identical to those isolated from organ spaces.CONCLUSION In patients undergoing PD,bile contamination is related to postoperative infectious complication including POPF Grade B/C.The management of biliary contamination should be standardised for patients who require preoperative biliary drainage for PD,as the main microorganisms are identical in both organ spaces and bile.
