Abstract:

Objective

To evaluate the effect and risk factors of donation after circulatory death (DCD) liver donor treated with retrograde perfusion on recovery of liver function in early stage after liver transplantation (LT).

Methods

Clinical data of 136 patients who underwent LT with DCD donors in Dongfang Hospital of Xiamen University from January 2015 to January 2020 were retrospectively analyzed. Among them, 115 patients were male and 21 female, aged from 20 to 70 years, with a median age of51 years. The informed consents of all patients were obtained and the local ethical committee approval was received. All patients were divided into the retrograde perfusion (n=86) and anterograde perfusion groups (n=28) according to different perfusion methods. After 1∶1 propensity score matching (PSM), 23 cases were assigned in each group. Postoperative recovery of liver function was compared between two groups. According to postoperative incidence of early allograft dysfunction (EAD), patients in the retrograde perfusion group were further divided into the EAD (n=5) and non-EAD groups (n=18). The effects of donor factors and donor liver perfusion method on EAD after LT were assessed by Logistic regression analysis. The predictive values of influencing factors were evaluated by the ROC curve.

Results

In the retrograde perfusion group, the median ALT levels at postoperative 3 and 7 d were 329(211, 548) and 176(98, 282) U/L,significantly lower than 451(288, 918) and 251(147, 430) U/L in the anterograde perfusion group (Z=-1.979, -2.299; P<0.05). In the retrograde perfusion group, the AST levels at postoperative 3, 5 and 7 d were 252(193, 522), 105(79, 163) and 93(41, 135) U/L, significantly lower than 328(251, 724), 179(129, 306) and 150(91, 200) U/L in the anterograde perfusion group (Z=-2.212, -3.221, -2.979; P<0.05). In the retrograde perfusion group, the TB levels at postoperative 5 d was 37(20, 106) μmol/L, significantly lower than 185(93, 193) μmol/L in the anterograde perfusion group (Z=-3.871, P<0.05). Logistic regression analysis suggested that Model for End stage Liver Disease (MELD) score was an independent risk factor for predicting EAD after LT. The area under the ROC curve of MELD score for predicting postoperative EAD was 0.678, and the optimal cut-off value was 25.5.

Conclusions

DCD liver donor treated with retrograde perfusion is more beneficial to the recovery of liver function in early stage after LT. Preoperative MELD score >25.5 is an independent risk factor for EAD after LT.
