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.\n\nThe study will enroll approximately 20 patients at BIDMC, and outcomes will focus on procedure-related complications, physiological measurements (ex., FEV1 by pulmonary function testing) and clinical symptoms (i.e., questionnaires). Patient will be followed for 3-month period, receiving usual standard of care during the 3 months of follow-up. The goal of this protocol is to determine if elimination of significant collateral lung ventilation between lung lobes is possible, and whether such strategy to eliminate collateral lung ventilation between lobes improves outcomes following subsequent EBV placement (i.e. promotes atelectasis of diseased lung segments) in the management of severe COPD\u002Femphysema in appropriate candidates.
