[The model of piggyback orthotopic liver transplantation in pigs]

To establish the pig model of piggyback orthotopic liver transplantation(PBOLT), twelve cases of pig PBOLT were performed. The result showed that ten pigs were survived after operation, and the operative successful rate was 83%. The mean operation time and mean anhepatic-phase time were 7 hours and 34 minutes, respectively. The mean bleeding amount was 1200 ml. The appearance and tissue structure of liver in every stage under optic microscope were normal. The results indicate that the pig model of PBOLT is feasible and that it is important to decrease the anhepatic-phase time for a successful liver transplantation.
