Bronchoscopy

Bronchoscopy is a technique of visualizing the inside of the airways for diagnostic and therapeutic purposes. An instrument (bronchoscope) is inserted into the airways, usually through the nose or mouth, or occasionally through a tracheostomy.

This allows the practitioner to examine the patient’s airways for abnormalities such as foreign bodies, bleeding, tumors, or inflammation. Specimens may be taken from inside the lungs. The construction of bronchoscopes ranges from rigid metal tubes with attached lighting devices to flexible optical fiber instruments with realtime video equipment.

Once the tube is inserted into the lungs, The doctor may send saline solution through the tube. This washes the lungs and allows the doctor to collect samples of lung cells, fluids, and other materials inside the air sacs. This part of the procedure is called a lavage.Sometimes, tiny brushes, needles, or forceps may be passed through the bronchoscope and used to take tissue samples (biopsies) from your lungs.

The pieces of lung material that are removed are small. The doctor can also place a stent in the airway or view the lungs with ultrasound during a bronchoscopy.
