Percutaneous transhepatic biliary drainage for biliary obstruction in perihilar cholangiocarcinoma: a 10-year analysis of safety and outcomes using the CCI index.

PTBD is safe and effective in the management of biliary obstruction caused by PCCA. Bismuth classification, locally advanced tumors, and failure to achieve clinical success in the first PTBD are factors related to major complications. Our sample reported a high major postoperative complication rate, although with an acceptable median CCI.
