Total Internal Biliary Diversion for Post-Liver Transplant PFIC-1-Related Allograft Injury.

Steatohepatitis and diarrhea are well-known complications in children undergoing liver transplantation (LT) for progressive familial intrahepatic cholestasis (PFIC) type 1. Despite medical management with bile acid binders, the condition is progressive and can be associated with allograft loss. We report the case of a seven-year-old boy who underwent LT at the age of 2 years for PFIC type 1. Over the next five years, he developed refractory diarrhea, emaciation, worsening liver function, and steatohepatitis. Aiming to interrupt the enterohepatic circulation, at the age of 7 years, he underwent a total internal biliary diversion. The patient's postprocedure period was uneventful. His diarrhea settled and the transaminases normalized his follow-up liver biopsy after a year showed a complete resolution of steatohepatitis. At 18 months' follow-up, he has gained weight and remains asymptomatic. In this report, we show post-LT complications especially allograft injury related to the pathology of PFIC-1 can be safely and effectively managed by performing a total internal biliary diversion.
