Because of the concerns regarding short & long-term outcomes after Liver Transplantation (LTx) using Donation after Circulatory Death (DCD) compared to Donation after Brain Death (DBD) donors, we reviewed the results of DCD-LTx at our center. Between 2003 and 2010, 30 DCD-LTx and 385 DBD-LTx were performed. Demographics, LTx indications, post-LTx peak aspartate amino transaminase (AST peak), delayed graft function (DGF) (Olthoff criteria), biliary non-anastomotic strictures (NAS), early post-LTx kidney dysfunction (RIFLE criteria), re-transplantation rate and patient/graft survival were analyzed. Mean DCD donor warm ischemia (stop ventilation to cold perfusion) was 23+/-11. Median cold ischemia was 6h54 for DCD compared to 8h40 for DBD-LTx; p=0.0001. Mean labMELD was similar for DCD and DBD-LTx (15 vs. 16; p=0.59). Median post-LTx AST peak was higher after DCD vs. DBD-LTx (1178 IU/L vs. 651 IU/L; p=0.005). DGF rate was similar between DCD and DBD-LTx (25 vs. 24%, p=0.8). The rate of NAS was higher after DCD vs. DBD-LTx (33% vs. 12%; p=0.001). Incidence of early post-LTx kidney dysfunction was not statistically different after DCD and DBD-LTx (37% vs. 23%, p=0.08). On the other hand, regardless the donor type, the AST peak – a surrogate of ischemia-reperfusion injury often used as an appropriate criterion for DGF evaluation – was associated with a higher rate of early post-LTX kidney dysfunction if greater than 2000 (28 vs. 10%, p=0.001) but not with NAS (12 vs. 15%, p=0.59). Re-transplantation rate within one year post-LTx was 3% after both DCD and DBD-LTx. The 1, 3, & 5-yr patient/graft survival were similar after DCD and DBD-LTx (93, 85, 85% vs. 88, 78 & 72%; p=0.3, and 90, 82, 82% vs. 85, 74 & 68%; p=0.5, respectively). Despite substantial ischemic injury, short& long-term patient/graft survival after DCD-LTx is comparable to DBD-LTx. Careful donor/recipient selection, rapid donor surgery and short ischemia times are key factors to optimize outcome after DCD-LTx. However, strategies to reduce ischemic injury and biliary complications remain warranted.
