    Abstract:
    Patients post liver transplant (LT) with progressive familial intrahepatic cholestasis type 1 (PFIC-1) often develop progressive graft steatohepatitis, intractable diarrhea, and growth failure. A total internal biliary diversion (TIBD) during an LT may prevent or reverse these adverse events. Children with PFIC-1 who underwent an LT at our institute were divided into 2 groups, A and B based on the timeline where we started offering a TIBD in association with LT. Pre-LT parameters, intraoperative details, and posttransplant complications like graft steatosis and diarrhea were also analyzed between the 2 groups, and their growth velocity was measured in the follow-up period. Of 550 pediatric LT performed between 2011 and 2022, 13 children underwent LT for PFIC-1. Group A had 7 patients (A1-A7) and group B had 6 (B1-B6). Patients A1, A4, B4, and B5 had a failed partial internal biliary diversion before offering them an LT. Patients A1, A2, and A6 in group A died in the post-LT period (2 early allograft dysfunction and 1 posttransplant lymphoproliferative disorder) whereas A3, A4, and A5 had graft steatosis in the follow-up period. A4 was offered a TIBD 4 years after LT following which the graft steatosis fully resolved. In group B, B1, B2, B5, and B6 underwent TIBD during LT, and B3 and B4 had it 24 and 5 months subsequently for intractable diarrhea and graft steatosis. None of the patients in group B demonstrated graft steatosis or diarrhea and had good growth catch-up during follow-up. We demonstrate that simultaneous TIBD in patients undergoing LT should be a standard practice as it helps dramatically improve outcomes in PFIC-1 as it prevents graft steatosis and/or fibrosis, diarrhea, and improves growth catch-up.
