Success rate of implanting prosthesis into the bile duct is 90%, leading to improvement of jaundice in 80% of the cases. The endoprosthesis occlude on the average after 3 months by incrustation and then have to be replaced. The clinical relevance of draining the pancreas by this procedure cannot yet be evaluated because of lack of sufficient experience.
