title: [Metallic endoprostheses in the treatment of benign strictures of the biliary tract].
abstract: Nine original nitinol self-smoothing-out stents and 3 Gianturco stents were implanted to treat benign strictures of biliary ducts and biliodigestive anastomosis after ineffective repeated attempts to make balloon dilatation. There were no complications associated with the implantation procedure. The follow-up of patients varied from 3 to 26 months. After 4 months, reobturation was revealed at the site of repair in one case, which required implantation of an additional stent coated with polytetrafluoroethylene. The patency of the biliary tract was preserved in the remaining patients in the above period.
