    Utilization of donation after circulatory death donor (DCD) livers for transplantation has remained cautious in the U.S. The aim of this study was to demonstrate the expansion of DCD liver transplant (LT) program with the use of extended criteria DCD livers. After institutional review board approval, 135 consecutive DCD LTs were retrospectively studied. ECD DCD livers were defined as those with one of the followings: 1) donor age >50 years, 2) donor BMI >35 kg/m2, 3) donor functional warm ischemia time (fWIT) >30 minutes, and 4) donor liver macrosteatosis >30%. An optimization protocol was introduced in July 2011 to improve outcomes of DCD LT, which included thrombolytic donor flush, and efforts to minimize ischemic times. The impact of this protocol on outcomes was evaluated in terms of graft loss, ischemic cholangiopathy (IC) and change in DCD LT volume. Of 135 consecutive DCD LT, 62 were ECD DCDs. 24 ECD DCD LT were performed before (Era I) and 38 after the institution of optimization protocol (Era II), accounting for an increase in the use of ECD DCD livers from 39% to 52%. Overall outcomes of ECD DCD LT improved in Era II, with a significantly lower incidence of IC (5% vs. 17% in Era I; P = 0.03) and better 1‐year graft survival (93% vs. 75% in Era I, P = 0.07). Survival outcomes for ECD DCD LT in Era II were comparable to matched deceased donor (DBD) LT. With the expansion of the DCD donor pool, the number of DCD LT performed at our center gradually increased in Era II to account for > 20% of the center's LT volume. In conclusion, with the optimization of perioperative conditions, ECD DCD livers can be successfully transplanted to expand the donor pool for LT.
