Risk factors of liver abscess and biloma formation after drug-eluting bead transarterial chemoembolization for unresectable intrahepatic cholangiocarcinoma.

Background And Study Aims: Drug-eluting bead transarterial chemoembolization (DEB-TACE) causes serious complications, including liver abscess and biloma formation. This study aimed to investigate the frequency and risk factors of liver abscess and biloma formation after dug-eluting bead transarterial chemoembolization for unresectable intrahepatic cholangiocarcinoma (ICC).

Patients And Methods: 152 unresectable ICC patients received 241 DEB-TACE procedures from February 2018 to November 2022 were studied retrospectively.
