Combined Thoracoscopic Surgical Stapling and Endobronchial Valve Placement For Lung Volume Reduction With Incomplete Lobar Fissures: An Experimental Pilot Animal Study.

Background: In patients with severe emphysema and complete fissures, bronchoscopic lung volume reduction with valves reduces target lobe volume providing improvement in respiratory symptoms, lung function, quality of life, and exercise capacity. It is estimated that up to 88% of patients with emphysema have at least 1 incomplete interlobar fissure. The aim of this study was to evaluate the feasibility of creating a complete fissure with stapling via minimally invasive video-assisted thoracoscopic surgery (VATS) followed by bronchoscopic valve placement to induce lobar collapse in a swine model.
