Percutaneous transhepatic therapy of bile duct stones and strictures.

Two patients, one with bile duct stones above a strictured biliary-enteric anastomosis, and the second with posttraumatic intra- and extrahepatic bile duct strictures, were treated via the percutaneous transhepatic route. The stones were removed and the strictures dilated. Surgery was unnecessary in the first patient, and in the second, exploratory laparotomy confirmed the efficacy of percutaneous transhepatic dilatation.
