Pediatric liver retransplantation from living donors can be considered as a therapeutic option for patients with irreversible living donor graft failure

Abstract

Liver retransplantation (re-LT) is required in patients with irreversible graft failure, but it is a significant issue that remains medically, ethically, and economically controversial, especially in living donor liver transplantation (LDLT). The aim of this study was to evaluate the outcome, morbidity, mortality, safety and prognostic factors to improve the outcome of pediatric living donor liver retransplantation (re-LDLT). Six of 172 children that underwent LDLT between January 2001 and March 2010 received a re-LDLT and one received a second re-LDLT. The overall re-LDLT rate was 3.5%. All candidates had re-LDLT after the initial LDLT. The overall actuarial survival of these patients was 83.3% and 83.3% at one and five yr, respectively. These rates are significantly worse than the rates of pediatric first LDLT. Vascular complications occurred in four patients and were successfully treated by interventional radiologic therapy. There were no post-operative biliary complications. One case expired because of hemophagocytic syndrome after re-LDLT. Although pediatric re-LDLT is medically, ethically, and economically controversial, it is a feasible option and should be offered to children with irreversible graft failure. Further investigations, including multicenter studies, are therefore essential to identify any prognostic factors that may improve the present poor outcome after re-LDLT.
