Bronchoscopy

  Back

Bronchoscopy is the technique of placing a flexible endoscope via the mouth down the trachea (windpipe) and into the bronchi (airways of the lungs). This provides direct visualisation of the airways under magnification and allows samples to be taken under endoscope guidance. A technique called bronchoalveolar lavage or BAL. This is useful in the investigation of coughing patients and patients with other respiratory signs.
