Negative prognostic outcomes of percutaneous transhepatic biliary drainage in distal cholangiocarcinoma: a retrospective analysis using propensity score matching

The efficacy of different types of preoperative biliary drainage for cholangiocarcinoma has been debated over the past two decades. Controversy concerning the use of percutaneous transhepatic biliary drainage (PTBD) versus endoscopic biliary drainage (EBD) still exists. This study aimed to compare the long-term outcomes between PTBD and EBD in patients with distal cholangiocarcinoma. Data of patients diagnosed with distal cholangiocarcinoma who...
