A bronchoscopy is an examination done with a thin, flexible fiberoptic tube called a bronchoscope. The tube is inserted through the nose or mouth into the lung.
This test is performed when lung disease, infections, tumors, or an obstruction are suspected.
With the person relaxed and lying down on a table or bed, a local anesthetic is sprayed into the throat and a mild sedative is given. When the throat is numb, the bronchoscope is inserted through the nose or mouth into the bronchi, or large airways in the lungs. Once the tube is in the lung, a small amount of fluid is sprayed into the lung. The fluid is then removed and sent to the laboratory for analysis. Respiratory tissues can then be observed and biopsied.
Specific instructions will be provided by the healthcare professional.
Results are normal when the air passages and the lavage show no abnormalities. Results are abnormal when the bronchoscope reveals diseases of the lungs, or the washings show the presence of infectious or cancer cells.
