For example, a small laser put on the end of a bronchoscope can be used to burn away part of a tumor that is blocking an airway. (This is known as transbronchial needle aspiration, or TBNA.) To treat certain lung problemsīronchoscopy can be used to treat blocked airways or some other types of problems in the lung. If suspicious areas such as enlarged lymph nodes are seen, a hollow needle can be passed through the bronchoscope and guided into these areas to obtain a biopsy. The transducer gives off sound waves and picks up the echoes as they bounce off these structures, and the echoes are converted into an image on a computer screen. It is passed down into the airways and can be pointed in different directions to look at nearby lymph nodes and other structures. For this test, a bronchoscope is fitted with a microphone-like instrument called a transducer on its tip. To look at lymph nodes near your lungsīronchoscopy can be done as part of an endobronchial ultrasound (EBUS) to look at the lymph nodes and other structures in the area between the lungs. (This is known as a bronchial washing.) The biopsy samples are then looked at in the lab. The doctor can also sample cells from the lining of the airways by passing sterile saltwater down the bronchoscope to rinse the airways, and then suctioning up the fluid. This is done by passing long, thin instruments down the bronchoscope, such as small forceps (tweezers), hollow needles, or brushes to collect the samples. You have a suspicious area that might be cancerīronchoscopy can be used to look at an abnormal area seen on an imaging test (such as a chest x-ray or CT scan).Īny abnormal areas in the airways that are seen with the bronchoscope can be biopsied to find out if they are cancer. This test can be used to look for the causes of problems in the airways of the lungs (such as trouble breathing or coughing up blood). There are a few reasons you might need a bronchoscopy: To find out why you are having lung problems
