Biliary-Pleural Fistula following Portal Vein Embolization for Perihilar Cholangiocarcinoma

Abstract

Biliary-pleural fistula (BPF), an abnormal communication between the biliary tract and pleural space, is a rare but potentially life-threatening complication following percutaneous biliary intervention. We report a case of BPF following portal vein embolization (PVE) in a 79-year-old woman with obstructive jaundice secondary to perihilar cholangiocarcinoma. The patient successfully underwent right-sided PVE; however, the patient developed a symptomatic right-sided bilious pleural effusion the following day. Despite aggressive drainage of the pleural effusion with a large-bore chest tube and maximal medical management, the patient died from respiratory failure and pneumonia. Although rare, knowledge of this complication is important when performing PVE in patients with biliary obstruction because it can be life-threatening. Early recognition and management of this complication are crucial to avoid a poor outcome.
