Bronchoscopy, rigid or flexible, including fluoroscopic guidance, when performed; with balloon occlusion, with assessment of air leak, with administration of occlusive substance (eg, fibrin glue), if performed

A bronchoscopy, whether performed using a rigid or flexible instrument, is a medical procedure that allows for direct visualization of the airways, including the trachea and bronchi. During this procedure, a bronchoscope is inserted through the patient's nose or mouth and advanced into the oropharynx, which is the part of the throat located behind the mouth. Fluoroscopic guidance may be utilized to enhance the visualization of the airways as the bronchoscope is maneuvered. This guidance is particularly useful in assessing the anatomy and identifying any abnormalities within the airways. The examination typically includes the oropharynx, vocal cords, and trachea, with a focus on the mainstem bronchus, which branches into the lungs. In cases where a rigid bronchoscope is employed, a telescope or flexible bronchoscope can be introduced through the rigid device to provide a clearer view of the distal segments of the mainstem bronchus. This is crucial for identifying the precise location of any air leaks, which can occur due to various medical conditions. Once the site of the air leak is identified, a balloon catheter is introduced and inflated at the leak site to occlude it. Following this, closure of the air leak may be attempted using various occlusive substances, such as fibrin glue, gelfoam, silicone plugs, or other adhesives. After the procedure, the bronchoscope is carefully withdrawn, allowing for a more thorough examination of the bronchus, trachea, vocal cords, and oropharynx during the withdrawal process. This comprehensive approach ensures that any potential issues within the airways are adequately assessed and addressed.
