Objective  To systematically evaluate the efficacy and safety of single lung transplantation (SLT) and bilateral lung transplantation (BLT) in the treatment of end-stage chronic obstructive pulmonary disease (COPD). Methods  Chinese and English databases were searched by computer, including PubMed, Web of Science, The Cochrane Library, EMbase, CNKI, Wanfang database, VIP database and CBM. Case-control studies on single lung transplantation or bilateral lung transplantation for COPD were collected from the inception to July 31, 2022. We evaluated the quality of the literature via Newcastle-Ottawa Scale. All results were analyzed using Review Manager V5.3 and STATA 17. Results  A total of 14076 patients were included in 8 literatures, including 8326 patients in the single lung transplantation group and 5750 patients in the bilateral lung transplantation group. The results of meta-analysis showed that there was no significant difference in the 1-year postoperative survival between the two groups (P=0.070). The 2-year survival rate (P=0.002), 3-year survival rate (P<0.001), 5-year survival rate (P<0.001), overall survival rate (P<0.001), postoperative forced expiratory volume in one second/predicted value (P<0.001), postoperative forced vital capacity (P<0.001), postoperative 6-minute walking distance (P=0.002) were lower or shorter than those in the bilateral lung transplantation group, the postoperative intubation time (P=0.030) was longer than that in the bilateral lung transplantation group. Bilateral lung transplantation group showed better surgical results. There were no statistical differences in the mortality, obliterative bronchiolitis, length of hospitalization, primary graft dysfunction, or postoperative adverse events (P>0.05). Conclusion  Bilateral lung transplantation is associated with better long-term survival and postoperative lung function compared with single lung transplantation. In-hospital mortality and postoperative complications were similar between them.
