💬In plain words
What the trial is, and whether it could suit you
The purpose of this protocol is to perform a pilot prospective randomized controlled clinical trial to evaluate the potential role of lung fissure completion strategy (experimental intervention) in addition to endobronchial valve (EBV) placement (representing "standard-of-care") in select patients with severe COPD/emphysema and with evidence for \<95% fissure completion between adjacent lung lobes. In select patients, lung fissure completion strategy will be performed by either video-assisted thorascopic surgery (VATS)-guided or robotic-guided stapling along the lung fissures in an attempt to reduce collateral ventilation and determine whether or not this experimental strategy will improve outcome following subsequent EBV placement. EBV placement will follow successful VATS-guided or robotic-guided fissure stapling.
The study will enroll approximately 20 patients at BIDMC, and outcomes
