Use of angioplasty balloons in the percutaneous management of biliary calculi: tandem-balloon method.

摘要: Interventional radiologic techniques are important in the nonsurgical management of calculous biliary disease. Stones may be removed by using baskets or forceps, they crushed and allowed to pass down common bile duct (with without dilatation sphincter Oddi), pushed with balloons through into duodenum.

This was successful four cases which conventional methods had failed. The following is description representative case.
