title: [Comparative study of reduced-size and whole liver transplantation in children].
abstract: It is difficult to find adequate donors for many children with low weight. In order to increase the pool size of donors and decrease mortality on the waiting list, several reduction techniques have been developed in the last years (reduced, segmental and split liver). The aim of this study is to compare morbility and mortality in our serie between children who received a full-size liver and those who received a partial one. We retrospectively compared 27 cases of reduced-size liver transplants (RLTx) with 102 cases of full-size liver transplants (FLTx) performed between june of 1985 and february of 2000. Mean age in RLTx was 38.1 months (range 6-144) vs 70.8 months (range 5-192) in FLTx. Mean weight was 11.9 k (range 5.8-30) in RLTx vs 20.48 k (range 4.4-68) in FLTx. Mean donor/recipient body ratio was 4.88 in RLTx and 2.03 in FLTx. The indication of transplantation was urgent in 14 patients (51.8%) from the RLTx group and in 12 (11.7%) from the FLTx one. The requirements of transfusions during surgery was greater in the RLTx (177 cc/kg of RBC transfusions vs 124 cc in FLTx). There was no differences between both groups regarding other postoperative complications (portal thrombosis, need of reintervention and biliary complications). Arterial thrombosis was observed only in FLTx (12 cases). Graft survival at 3 months was 49% for the RLTx and 73% for the FLTx. It was 43% and 67%, respectively, at 1 year, and 43% and 53% at 5 years after liver transplantation (p = 0.06). If we consider only elective transplants, survival was 72% for RLTx and 75% for the FLTx at 3 months. Although survival is lower in the RLTx group, the difference is not significant. If we consider only the elective transplants, survival is almost the same in both groups. The reduction techniques are a good method to decrease mortality in the waiting list without increasing post-transplant morbidity and mortality.
