Internal biliary diversion using appendix during liver transplantation for progressive familial intrahepatic...

Progressive familial intrahepatic cholestasis type 1 (PFIC-1) is a genetic cholestatic disease causing end-stage liver disease, which needs liver transplantation (LT). Simultaneous biliary diversion (BD) was recommended to prevent allograft steatosis after transplantation, while increasing the risk of infection. Here, an attempt was made to perform BD using appendix to prevent bacterial translocation after LT.

An 11-month-old boy diagnosed with PFIC-1 received ABO compatible living donor LT due to refractory jaundice and pruritus. His mother donated her left lateral segment with a graft-to-recipient weight ratio of 2.9%. Internal BD was constructed during LT using the appendix by connecting its proximal end with the intrahepatic biliary duct and the distal end with colon. Biliary leakage was suspected on the 5^th day after transplantation and exploratory laparotomy indicated biliary leakage at the cutting surface of liver. The liver function returned to normal on the 9^th day post-operation and maintained normal during the 15-month follow-up. Cholangiography at 10 months after transplantation confirmed the direct secretion of bile into colon. Computerized tomography scan (4 months and 10 months) and liver biopsy (10 months) indicated no steatosis in the allograft. No complaint of recurrent diarrhea, infection or growth retardation was reported during follow-up.

Internal BD using appendix during LT is effective in preventing allograft steatosis and post-transplant infection in PFIC-1 recipients.
