Impact of biliary drainage method before pancreaticoduodenectomy on short- and long-term outcomes in patients with periampullary carcinoma and obstructive jaundice: A multicenter retrospective analysis.

In biliary tract cancer, percutaneous transhepatic biliary drainage may carry the risk of increasing the incidence of disseminative recurrence. In pancreatic cancer, percutaneous transhepatic biliary drainage is preferable owing to fewer complications without influencing recurrence. However, if patients cannot undergo surgery immediately, endoscopic retrograde biliary drainage will be applicable to help the preservation of nutritional status, which can have an impact on survival.
