Bronchoscopy is an examination of your windpipe and air passages by means of a flexible telescope.
Like an endoscopy to look at the stomach, bronchoscopy is a test that your doctor will suggest when there is a need to have a look in the air passages, or take samples from the lung when testing for certain diseases.
Unlike x-rays which take photographs of the lung, a bronchoscopy lets the doctor see inside the windpipes, an area not clearly shown on x-rays. Bronchoscopy can also help in making the diagnosis and in planning the right treatment for people with lung disease.
The procedure takes about 15 to 30 minutes. If you were given a sedative, you will usually recover and go home after about 2 hours. A friend or relative is needed to accompany the patient on discharge.
