BackgroundArguments against biliary drainage before pancreatoduodenectomy have been gaining momentum recently. The benefits of biliary drainage before hepatobiliary resection, ie, combined liver and extrahepatic bile duct resection, however, are still debatable.ObjectiveTo review the outcomes of patients who underwent hepatobiliary resection, with special attention to preoperative biliary drainage, to investigate whether biliary drainage increases the risk of postoperative infectious complications.MethodsThis study involved 587 patients who underwent hepatobiliary resection with cholangiojejunostomy, including 475 patients who underwent preoperative biliary drainage and 112 patients who did not. Before each operation, surveillance bile cultures were performed at least once a week. Postoperatively, the bile and drainage fluid were cultured on days 1, 4, and 7. The hospital records of consecutive patients who underwent hepatobiliary resection were reviewed retrospectively.ResultsOf the 475 patients with biliary drainage, 356 (74.9%) had a positive bile culture during the preoperative period. The incidence of postoperative infectious complications, including surgical-site infection and bacteremia, was similar between patients with biliary drainage and those without (28.2% vs 28.6%, P = .939). A positive bile culture during the perioperative period was highly associated with infectious complications and was one of the independent predictive factors related to infectious complications in a multivariate analysis.ConclusionPreoperative biliary drainage is unlikely to increase the incidence of infectious complications after hepatobiliary resection. Perioperative surveillance bile culture is useful for the perioperative selection of appropriate antibiotics because of the high likelihood that micro-organisms isolated from infected sites are identical to those isolated from bile.Copyright © 2013 Mosby, Inc.
