| Popis: | Mortality among patients on a waiting list for orthotopic liver transplantation continues to be 10-15%; this is of particular concern in the pediatric population and may become more problematic in adult patients as longer waiting lists for cadaveric transplantation accrue. The longer cold ischemia times afforded by use of University of Wisconsin (UW) solution and improved hepatic surgery techniques have allowed the development of reduced-size liver transplantation (RSLT), split-liver transplantation (SLT), and living-related liver transplantation (LRLT). These new surgical techniques have been predominantly employed in children, up to 40% of whom may be candidates for one of these modified procedures. With the exception of SLT, these approaches have been associated with comparable rates of biliary tract and vascular complications, rejection episodes and graft and patient survival when compared to whole organ transplantation. Right hepatic lobe graft recipients have approximately 15% decreased graft survival rates, limiting the acceptance of SLT as a standard approach to decrease waiting list times. Application of LRLT to the adult population, where 5-10% of recipients are potential candidates, is expected to increase. Over 100 LRLTs have been performed worldwide and while recipient survival with LRLT is excellent, concerns about donor morbidity and mortality, psychosocial factors and reimbursement issues remain obstacles. Living-unrelated liver transplantation and auxiliary orthotopic partial liver transplantation are developing approaches to be considered only in highly selected cases. |
