Obstruction of the Roux limb after portoenterostomy for biliary atresia: a delayed complication.

We report the case of a 5-year-old girl who underwent a Kasai portoenterostomy for extrahepatic biliary atresia. The conduit was exteriorized until 11 months of age. She was doing well, with stable portal hypertension until she suddenly developed jaundice, acholic stools, and bacteremia not responsive to a course of steroids and intravenous antibiotics. Suspecting obstruction at the site of the previously exteriorized anastomosis, a percutaneous cannulation of the conduit was performed. Catheterization of the conduit obstruction unkinked it and reestablished bile flow. She has remained anicteric with stable liver function.
