title: A case of bilioduodenal fistula treated with a self-expandable metallic stent.
abstract: We report the case of a 72 year-old female patient who suffered from biliary fistulae. The biliobiliary and bilioduodenal fistulae appeared after an operation for biliary bleeding. Conventional therapy for biliary fistula would be the disconnection of the fistula by either conservative or operative treatment. In the present case, however, it was preferable to enlarge the fistula to drain bile juice into the duodenum, rather than to close the fistula because it would have been difficult to achieve a tight adhesion with this operation. The enlargement by a plastic tube stent failed to drain the bile juice into the duodenum, because the sludge made the tube stenotic. Therefore, a self-expandable metallic stent was applied in this case. An expandable stent was used because a large final caliber is necessary to prevent stenosis of the fistula by sludge and mucosal hyperplasia. After insertion of a self-expandable metallic stent by the percutaneous transhepatic biliary drainage route, the patient has not suffered from cholestasis and cholangitis for the last 30 months. It can therefore be concluded that enlargement of the fistula by a self-expandable metallic stent is a convenient therapy for such biliointestinal fistulae.
