The majority of patients with periampullary malignancies currently undergo biliary drainage before pancreaticoduodenectomy. Placement of an endoprosthesis reliably ameliorates jaundice and pruritus. However, preoperative biliary drainage leads to bile colonization and increases the risk of postoperative wound infection after pancreatic resection. Preoperative biliary drainage does not appear to lower postoperative morbidity or mortality following pancreatic resection and does not lower but probably increases costs associated with pancreatic resection. Preoperative biliary drainage is frequently used with little clinical benefit and its utilization should be limited to specific clinical indications, i.e. patients receiving neoadjuvant therapy, patients waiting several weeks or more for surgical evaluation and resection, patients with cholangitis. |
