Evaluation of percutaneous transhepatic balloon dilatation of benign biliary strictures in high-risk patients

During the period from 1979 through 1984, 17 patients with benign biliary strictures underwent percutaneous transhepatic balloon dilatation. All patients presented with either hyperbilirubinemia and acute cholangitis, a history of intermittent chills and fever, or both. Balloon dilatation was most successful in those patients with intrahepatic strictures, sclerosing cholangitis, strictured biliary enteric anastomoses, and distal common bile duct strictures with retained calculi. Two patients with postsurgical common bile duct injury had treatment failure 3 and 18 months after dilatation and subsequently underwent elective hepaticojejunostomy. Although our longest treatment success is now more than 4 1/2 years in an 83 year old woman who is 15 years posthepaticojejunostomy, the mean follow-up of the entire group has only been 2 years. On the basis of our early experience and that of others, we now recommend an initial attempt at balloon dilatation in most patients with postsurgical benign biliary strictures. Further technical advances and longer follow-up in present and future series may certainly broaden the appeal of this nonoperative procedure.
