Best Biliary Drainage Option in Advanced Klatskin Tumor

Best Biliary Drainage Option in Type II、III、IV Klatskin Tumor：ERCP or PTBD

To investigate the biliary drainage-related cholangitis and other complications of percutaneous transhepatic biliary drainage (PTBD) in the management of Klatskin tumor (KT) compared with endoscopic biliary drainage (EBD).

Operative treatment combined with preoperative biliary drainage (PBD) has been established as a safe management strategy for KT. Preoperative cholangitis was an independent risk factor for patients undergoing resection for KT. However, controversy exists regarding the preferred technique for PBD.
