Core Tip

Core tip: This study aimed to evaluate the effect of preoperative biliary drainage and bile contamination on the outcomes of patients who undergo pancreaticoduodenectomy (PD). 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%). In patients undergoing PD, bile contamination is related to postoperative infectious complication including postoperative pancreatic fistula 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.
