Endobronchial Ultrasound

Endobronchial ultrasound (EBUS) has emerged as a routinely performed procedure in diagnostic bronchoscopy. Extending theview beyond the airway wall, EBUS provides evaluation of tumor involvement of tracheobronchial wall and mediastinum and playsan essential role as a guidance technique for peripheral pulmonary diseases. The latest development is the EBUS-transbronchialneedle aspiration (TBNA) scope that allows performing real-time EBUS-TBNA of enlargerd hilar and mediastinal lymph nodes.
