Biliary obstruction due to hepatic echinococcus alveolaris: Palliative treatment by transhepatic placement of an expandable biliary endoprosthesis
A case report is presented of a 60-year-old patient with a 10-year history of Echinococcus alveolaris infection involving the right hepatic lobe during mebendazole therapy. A proximal biliary obstruction involving the common hepatic and left hepatic ducts was treated by transhepatic placement of a self-expanding metal endoprosthesis. The jaundice has been relieved, and stent occlusion has not occurred during a 2-year follow-up with continued mebendazole treatment. The patient is currently asymptomatic. The results of this method of treatment for biliary obstruction due to unresectable Echinococcus infection are encouraging. The metal endoprostheses seem to have advantages for extraductal biliary compression. © 1991.
