Endoscopic Diagnosis of Chest, Lung Problems
You’ve been told you need an endoscopic procedure to diagnose a problem in your chest or lung. This procedure allows your doctor to view the airway of your lungs and take a tissue sample (biopsy) if needed.
A bronchoscopy allows the doctor to look directly into the airways in your lungs. This is done using a bronchoscope. A bronchoscope is a thin, flexible, hollow, lighted tube that lets the doctor see inside the lung. Tools can be passed down the middle of the scope.
Transbronchial biopsy (TBB) is a procedure used mainly to take samples of tissue near the airway. This is done using a bronchoscope and tiny forceps. The forceps are passed through the scope into the airway, and a sample is taken.
Endobronchial ultrasound (EBUS) is a type of bronchoscopy. With EBUS, the lungs and the space between the lungs (mediastinum) are looked at using a flexible bronchoscope and ultrasound (images created using sound waves). Ultrasound guides the doctor and allows him or her to see through the airway walls.
Preparing for the Procedure
Before your procedure, do the following:
Follow your doctor’s instructions about eating and drinking.
Tell your doctor about the medications you take. You may need to stop taking some of them before the procedure, especially aspirin, Coumadin, or other blood thinners.
Talk with your doctor about any allergies and health problems you have.
Tell your doctor if you are pregnant.
During the Procedure
You will get medication to help you relax (sedation) through an intravenous (IV) line. You may also receive local anesthesia (numbing medication) with a needle. Then a special spray is used to numb your throat and nose or mouth. This is to help keep you comfortable and prevent coughing during the procedure.
After the Procedure
You are sent to the recovery room until the sedation wears off. This takes about
Risks and Complications
