Radial probe EBUS can be used to guide biopsy during peripheral bronchoscopy. This technique provides real-time ultrasound-based confirmation of target lesion localization prior to biopsy. Using radial probe EBUS, the vast majority of peripheral pulmonary nodules can be identified. Radial EBUS probe position relative to the target lesion significantly affects the diagnostic yield.

We report the first multicenter study to date confirming the feasibility and utility of EBUS-TBNA in the pediatric population. Due to the low overall procedural risk of EBUS-TBNA, it should be considered as a potential first line diagnostic option for children presenting with mediastinal or hilar abnormalities but further prospective studies are needed.

We present the largest, multicenter study of patients undergoing evaluation for intrabronchial valve use for air leak management. Our data suggest the majority of intrabronchial valve placements are occurring for off-label indications. Although the use of intrabronchial valves are a minimally invasive intervention for air leak management, the lack of rigorously designed studies demonstrating efficacy remains concerning. Prospective randomized controlled studies remain warranted.

Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are important events in the lives of patients with COPD. While several definitions exist for AECOPD, exacerbations that result in a hospitalization would nearly always be considered severe. On average, exacerbation rates are approximately 1 to 2 per patient-year with COPD hospitalizations averaging approximately 0.1 to 0.2 per patient-year. Many risk factors, some of which are modifiable, such as patient adherence to therapy, pulmonary rehabilitation, and type of medication used, influence the rate of AECOPD. Severe AECOPD that result in hospitalization often lead to several adverse affects, including decreased quality of life, diminished lung function, weakness, reexacerbations/rehospitalization, cardiopulmonary complications, and death. Preventing severe AECOPD and their sequelae is a critical component in treating our patients with COPD.

Peripheral pulmonary lesions are an increasingly common finding in clinical practice. While many nodules are followed with radiographic surveillance, some may require biopsy. Conventional bronchoscopy with transbronchial lung biopsy has traditionally performed poorly for small, peripheral lesions, and transthoracic needle aspiration with computed tomographic (CT) guidance has been favored as the diagnostic test of choice. Despite the high diagnostic yield of transthoracic needle aspiration, procedural complications such as pneumothorax continue to be problematic. New technology has been developed to improve the diagnostic yield of bronchoscopy for peripheral lesions over conventional methods, while maintaining the favorable safety profile of a bronchoscopic approach. Virtual bronchoscopy and electromagnetic navigation are CT-based image guidance systems that create virtual bronchoscopic representations of the tracheobronchial tree to assist the bronchoscopist in locating peripheral lesions. Radial probe endobronchial ultrasound utilizes real-time ultrasound to confirm the location of peripheral lesions before biopsy. This article summarizes the technical platforms, procedures, and clinical evidence for these emerging technologies.

Patients with SARS-CoV-2 pneumonia can suffer from pneumothorax and persistent air leak (PAL). The pneumothorax occurs with or without pre-existing lung disease. PAL refers to air leak lasting more than 5–7 days and arises due to bronchopleural or alveolopleural fistula. The management of PAL can be challenging as a standard management guideline is lacking. Here we present the case of a 42-year-old smoker with COVID-19 who presented to the hospital with fever, cough, acute left-sided chest pain and shortness of breath. He suffered from a large left-sided pneumothorax requiring immediate chest tube drainage. Unfortunately, the air leak persisted for 13 days before one-way endobronchial valve (EBV) was used with complete resolution of the air leak. We also review the literature regarding other cases of EBV utilisation for PAL in patients with COVID-19.
