    ABSTRACT: Purpose of review: In the past few years, there have been exciting developments in bronchoscopic efforts at attaining lung volume reduction (LVR), given real and perceived risks of surgical LVR. The purpose of this review is to discuss these techniques, with special emphasis on what we have learnt in the past 1-2 years. Recent findings: Bronchoscopic techniques can be broadly classified as one-way valves, which allow air to exit but not enter, thus reducing air trapping; airway bypass stents, which create an extra-anatomical pathway for air to exit; biologic and polymeric substances, which seal the emphysematous lung, eventually collapsing it; bronchial thermal vapor ablation, which causes thermal damage and thus achieves LVR; and endobronchial elastic coils, which mechanically cause LVR. The specific role of these is being defined by recent publications. The central role of collateral ventilation in choosing amongst these procedures is now established, as it has become clear that in the presence of collateral ventilation, valves provide only modest benefit, if any at all. Thus it is of interest that the other modalities which are independent of collateral ventilation are being studied further. Summary: Though the preliminary results are quite encouraging, further trials need to be done before these procedures can be adopted in daily practice.

    ABSTRACT: Air leaks are observed after lung surgery, but can also occur spontaneously even in a previously normal lung. There are several available methods of management including, among others, chest drainage, Heimlich valves, surgical repair or pleural decortication. However, in some of these patients, surgery may be contraindicated. In this article, the authors report the use of one-way endobronchial valves in the treatment of a compromised patient with bullous emphysema who had previously undergone bullectomy. This approach resulted in improvement of dyspnea and exercise capacity. Use of endobronchial valves is an effective, nonsurgical, minimally invasive intervention for patients with prolonged pulmonary air leaks not suitable for surgical procedures.

    ABSTRACT: The term "interventional pulmonology" (IP) supersedes the previously used term "thoracic endoscopy," a change that reflects the evolution of a specialty devoted to performing highly sophisticated and technologically advanced procedures in the lungs and chest. Continuing advances in technology promise to further expand IP's diagnostic and therapeutic frontiers. However, standardized educational programs to train and test IP physicians will be essential to maintain a high standard of practice in the field.
