Lung transplantations (LTx) have become an effective lifesaving treatment for patients with end-stage lung diseases. While the shortage of lung donor pool and severe posttransplantation complications exaggerate the obstacle of LTx. This meta-analysis aimed to evaluate the efficacy of donation after circulatory death (DCD) in LTx for patients with end-stage lung diseases.
PubMed, EmBase, and Web of Science were systematically searched for all relevant studies comparing the efficacy of DCD and conventional donation after brain death (DBD). The relative risk (RR) value as well as the weighted mean difference with a 95% confidence interval (CI) were pooled for dichotomous and continuous outcomes, respectively. The heterogeneity across the included studies was also assessed carefully.
Overall, 17 studies with 995 DCD recipients and 38 579 DBD recipients were included. The pooled analysis showed comparable 1-year overall survival between the 2 cohorts (RR 0.89, 95% CI, 0.74-1.07, P = 0.536, I2 = 0%). The airway anastomotic complications rate in DCD cohort was higher than that in DBD cohorts (RR 2.00; 95% CI, 1.29-3.11, P = 0.002, I2 = 0%). There was no significant difference between DCD and DBD regarding the occurrence of primary graft dysfunction grade 2/3, bronchiolitis obliterans syndrome, acute transplantation rejection, and length of stay. The stability of the included studies was strong.
Evidence of this meta-analysis indicated that the use of lungs from DCD donors could effectively and safely expand the donor pool and therefore alleviate the crisis of organ shortage.
