Role of Bronchoscopy in the Diagnosis and Treatment of Severe Asthma

Severe asthma can be difficult to manage. While not always indicated, bronchoscopy has a role in the diagnosis and management of asthma, particularly in ruling out other differential diagnoses. Additionally, the emergence of biologic therapies has changed the landscape for treating severe asthma, but bronchoscopic techniques such as bronchial thermoplasty (BT) may also play a role. More data has emerged regarding the longevity and efficacy of BT as well as in identifying ideal candidates. Other bronchoscopic techniques may also be useful in treating patients with severe asthma but more studies are needed. This review focuses on the use of bronchoscopy to aid in diagnosis and treatment of asthma with a focus on bronchial thermoplasty.
