[Biliary stents for reconstruction in bile duct injuries. The role of bile acids].

Unlabelled: Biliary stents, placed either surgically, endoscopically or radiologically are a frequent palliative and/or curative option for treatment of obstructive jaundice. Stones or sludge formation above or inside the stent are of major concern in that they cause dysfunction of the stent that needs prompt replacement. To evaluate the efficacy of ursodeoxycholic acid (UDCA) for long-term management of surgically placed biliary stents after iatrogenic injury, a prospective, controlled, randomized trial was conducted.
