Options for non-surgical tissue diagnosis of the peripheral nodule include CT scan-guided TTNA, fluoroscopy-guided bronchoscopy, radial endobronchial ultrasound (EBUS), electromagnetic navigation bronchoscopy (ENB), and virtual bronchoscopy navigation (VBN). For physicians who choose to pursue non-surgical biopsy, the decision to perform CT scan-guided or ultrasound-guided TTNA, conventional bronchoscopy or bronchoscopy guided by EBUS, ENB, or VBN will depend on a number of factors. CT scan-guided TTNA is preferable for nodules located near the chest wall or for deeper lesions, provided that there is no need to go through the fissures and there is no surrounding emphysema. ⋯ Trainees must possess a perfect knowledge of anatomy and be fully competent in the interpretation of imaging (CT with contrast medium and PET) and have a thorough knowledge of navigation technology in all its complexities. Practical training can be performed on animal, cadaver or plastic models. In the last years, to improve diagnostic yield, navigational bronchoscopy has attracted significant attention.

Bronchial thermoplasty (BT) is an innovative non-pharmacological endoscopic treatment for patients with severe persistent asthma based on controlled heat release with a device called Alair™ Catheter (Boston Scientific, Natick, MA, USA). The Alair™ system is the first device that works by delivering radiofrequency or thermal energy to selectively reduce the amount of airway smooth muscle (ASM) in bronchi. Literature showed significant improvement in clinical outcomes such as symptom control, severe exacerbation rate, hospitalization, quality of life, and number of working or school days lost for asthma. ⋯ Furthermore, right selection of severe asthma patient is crucial in order to have best response after BT. This article reviews BT device description and how to perform the procedure. Criteria for right selection and management of patient before and after BT will be discussed.
