Liver retransplantation in children.
Between January 1988 and December 1993, 132 children received 154 orthotopic liver transplantation (OLT) at Bicêtre Hospital (France). Among them, 18 children underwent two and 2 children underwent three transplants (retransplant rate; 15.2%). Retransplantations were classified into three groups according to the interval between both OLTs: 1 (< 7 days, n = 8), 2 (8 days to 6 months, n = 10) and 3 (> 6 months, n = 4). Each group was compared with a control group whose grafts survived more than 1 week. There were no significant differences regarding age (35 +/- 49, 23 +/- 13, and 33 +/- 15 versus 49 +/- 41 months), cold ischemic time (566 +/- 105, 470 +/- 144, and 476 +/- 58 versus 455 +/- 110 minutes) and reduced size graft ratio (62.5%, 60%, and 75%, versus 58.3%). The causes of graft failure included primary nonfunctioning liver (PNF, n = 8) all in group 1 cases, biliary complications associated with hepatic artery thrombosis (HAT, n = 10; group 2, 6; group 3, 4), chronic rejection (n = 3; group 2, 1; group 3, 2) and three others (uncontrollable acute rejection, fulminant hepatitis, and secondary dysfunction, all in the group 2). The authors were unable to detect the cause of PNF. The overall survival rate after retransplantation was 62.5%, 60.0% and 75%, respectively. To reduce the rate of retransplants and improve the prognosis after OLT, further investigation into the cause of PNF, refinements in the anastomotic technique of the hepatic artery, and also early treatment of HAT are some of the goals to be achieved.
