Biliary endoprostheses in tumors at the hepatic duct bifurcation

In 51 patients with tumors at the hepatic duct bifurcation, endoprostheses were transhepatically inserted into the bile ducts. Patients with Bismuth-3-tumors (i.e. bilateral biliary obstruction) were treated by insertion of 2 or more endoprostheses. Long-term success presumed drainage of all obstructed ducts, because cholangitis has been a common problem secondary to undrained segments. Furthermore the debris and the high viscosity of infected bile increased the risk for obstruction of the endoprostheses, which was observed in 6%. The mean time of survival was 7 months with a maximum of 26 months. In our experience endoprostheses can be used successfully in unresectable Klatskin tumours, which increases the comfort for the patients in their last months of life.
