Single vs. bilateral lung transplantation

Purpose of review Lung transplantation is a life-saving treatment for several end stage lung diseases. Over the last two decades, the number of lung transplantation performed worldwide has steadily increased but several thousand people still die every year waiting for lung transplantation. However, the optimal procedure for lung transplantation in non-septic lung conditions remains debatable. Recent findings In pulmonary fibrosis and COPD, many recent studies suggest superiority of bilateral lung transplantation over single lung transplantation when long-term survival is evaluated; consequently, bilateral lung transplantation has been favored by many lung transplantation centers. However, the quality of evidence to support the superiority of bilateral lung transplantation remains low in the absence of prospective studies, and other available studies do not show differences in outcomes between the two types of procedure. Summary In the absence of good high quality evidence, it is difficult to make strong general recommendations for the type of lung transplant, and the decision often has to be individualized. However, the number of recipients on the wait list continues to surpass the amount of available organs and due consideration needs to be given to single lung transplantation as an option whenever possible.
