Endoscopic Lung Volume Reduction Prior to Lung Transplantation Does Not Increase Postoperative Pulmonary Complications.

Lung transplantation (LTx) remains the only therapeutic option for selected patients with end-stage lung disease. In comparison to surgical lung volume reduction, few data exist on the risks and benefits of pretransplant endoscopic lung volume reduction (eLVR). Here, we investigate the risk of postoperative pulmonary complications (PPCs) after LTx in patients with emphysematous lung disease bridged with eLVR until transplantation. Eighty-two patients with emphysematous lung disease who underwent double-LTx (DLTx) were included and retrospectively evaluated. Statistical analysis was performed using SPSS and GraphPad Prism software. 28/82 patients underwent eLVR prior to DLTx. eLVR patients spent comparable time on the waitlist; however, they were older at the time of DLTx (median 60 vs. 58 years, p = 0.02). Both groups showed comparable 90-day (92%) and long-term survival (eLVR 1-/5-/10-year survival: 92/88/77%, vs. control: 89/77/67%, p = 0.5). The odds for PPCs were similar in patients with and without eLVR (OR 0.7; 95% CI: 0.3-1.7), as well as major perioperative surgical and cardiovascular complications. In the entire cohort, we found ≥1 PPC to be a risk factor for death within 90 days (OR 9.7, 95% CI: 1.3-110). Among the PPCs, pneumonia (HR 4.6 95% CI: 1.1-14.9, p = 0.02) and ARDS (HR 11.2 95% CI: 1.6-229.2, p = 0.04) were identified as independent risk factors for reduced long-term survival. eLVR does not increase the risk for PPCs, surgical complications, or reduced survival after LTx in patients with emphysematous lung disease and can serve as a bridge to LTx.
