ReviewBronchoscopic Lung Volume Reduction for Emphysema: Review and Update.
In carefully selected patients with severe chronic obstructive pulmonary disease, characterized by emphysema and hyperinflation, lung volume reduction is an option to reduce lung hyperinflation, improve lung function, quality of life, and exercise capacity. Currently, there are several bronchoscopic and surgical treatment options to achieve lung volume reduction. ⋯ Other bronchoscopic lung volume reduction options include treatment with coils, thermal vapor ablation, and sclerosant agents. In this review, we aim to summarize the current clinical evidence on the bronchoscopic lung volume reduction therapies and important aspects regarding optimal patient selection.

Interventional Pulmonology and Esophagus: Combined Endobronchial Ultrasound and Endoscopic Ultrasound for Mediastinal Staging.
Endoscopic ultrasound (EUS) techniques in addition to endobronchial ultrasound (EBUS) can lead to diagnosis and complete accurate staging of the mediastinum in a single session. This allows for decreased health care costs, less delay in diagnosis and treatment, reduced patient discomfort, and decreased morbidity compared with invasive surgical staging techniques. ⋯ Moreover, compared with EBUS alone, combined EUS and EBUS has significantly increased yield, as well as diagnostic sensitivity making a combined approach preferable as the emerging gold-standard technique for initial minimally invasive mediastinal staging. We discuss the advantage of using EUS in combination with EBUS and highlight techniques, lymph node landmarks, utility in staging and restaging of the mediastinum, roles in diagnosing mediastinal infections and granulomatous lesions, and future directions in endosonography.

Nodules, Navigation, Robotic Bronchoscopy, and Real-Time Imaging.
The process of detection, diagnosis, and management of lung nodules is complex due to the heterogeneity of lung pathology and a relatively low malignancy rate. Technological advances in bronchoscopy have led to less-invasive diagnostic procedures and advances in imaging technology have helped to improve nodule localization and biopsy confirmation. Future research is required to determine which modality or combination of complimentary modalities is best suited for safe, accurate, and cost-effective management of lung nodules.

ReviewTransbronchial Lung Cryobiopsy for Diffuse Parenchymal Lung Disease.
Transbronchial lung cryobiopsy (TBLC) offers a minimally invasive option for the diagnosis of diffuse parenchymal lung diseases, of which interstitial lung diseases comprise the most common diagnoses. It has a high diagnostic yield with prognostic and therapeutic implications. ⋯ However, TBLC techniques remain variable. Here we review the latest techniques described to maximize diagnostic yield and mitigate complications of TBLC as well as how this modality has been incorporated into guidelines.
