Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula.

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventional radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment of biliary strictures are discussed.
