(1) A procedure that permits the doctor to see the breathing passages through a lighted tube.
(2) A procedure that uses a bronchoscope to examine the inside of the trachea, bronchi (air passages that lead to the lungs), and lungs. A bronchoscope is a thin, tube-like instrument with a light and a lens for viewing. It may also have a tool to remove tissue to be checked under a microscope for signs of disease. The bronchoscope is inserted through the nose or mouth. Bronchoscopy may be used to detect cancer or to perform some treatment procedures.
(3) A diagnostic procedure in which a pulmonologist inserts a bronchoscope into the trachea, main stem bronchi, and some of the small bronchi. This procedure is typically used to take samples (biopsy) of suspicious lesions and for culturing specific areas of the lung.
A bronchoscope is a flexible tube less than 1/2 inch wide and about 2 feet long. It has a tiny camera on the end.
