Transhepatic Placement of Metallic Biliary Stent for Internal Drainage of Persistent Liver Abscesses

Transhepatic placement of a metallic biliary stent for internal drainage of persistent liver abscesses was performed in 9 patients (males; median age, 65 years; range, 57-82 years) with refractory liver abscess. The median follow-up period was 2.8 months (range, 0.4-50.3 months). Technical success was achieved in all cases without any major complications. Clinical success, defined as the removal of the drainage tube without recurrent symptoms of infection, was achieved in 8 cases. Median duration until removal of the drainage tube from stent placement was 7 days (range, 0-36).
