Clinical characteristics affecting the outcome of liver retransplantation

Background. The outcome of retransplantation remains unsatisfactory when compared with primary transplantation of the liver, The aim of the present study tvas to determine which preoperative clinical and laboratory risk variables are implicated in the poorer outcome. Methods. The preoperative status of 70 retransplanted patients was compared with a group of 303 time-matched recipients receiving their first graft. Results. Survival. at 1 year was reduced in the retransplant versus the primary transplant group (50% vs, 80%, P<0.001). Preoperatively older age, high United Network of Organ Sharing score, inpatient status, elevated bilirubin, and creatinine levels were associated with increased mortality after a second transplant. Preoperatively, the retransplant group had higher encephalopathy grades, were more likely to he inpatients, and had higher serum creatinine, bilirubin, and white cell levels than the primary recipients (P<0.05 in all cases). The median length of inpatient stay was longer after the second transplant (25 vs. 19 days, P<0.001). Conclusions. These factors assist in the stratification of patients awaiting retransplantation; however, the outcome of this procedure is only likely to be improved with an earlier identification of the patients whet require it, along with an increased priority in organ allocation.
