A Tale of 2 Techniques: Preoperative Biliary Drainage and Routine Surgical Drainage with Pancreaticoduodenectomy

Preoperative drainage of an obstructed biliary tree before pancreaticoduodenal resection (PDR) and placement of intraabdominal drains following pancreatic resection have been suggested to be both unnecessary and associated with a higher complication rate. The evidence for and against that practice is presented and analyzed to highlight its risks and benefits. A selective approach on an individual basis for preoperative biliary decompression is advocated, based on multiple factors. Additionally, the evidence for routine use of surgical drains after PDR is critically reviewed and the rationale for routine drainage is made.
