Bronchoscopy

Overview

In a bronchoscopy, a thin flexible tube with a camera (bronchoscope) is passed through the nose or mouth into the windpipe and the airways of the lungs. The doctor can look for problems and take samples such as fluid washings or small biopsies.

Why it is done

• To investigate a persistent cough, coughing up blood, or an abnormal chest X-ray or CT scan
• To take samples for infections such as tuberculosis or pneumonia
• To assess a possible lung tumour
• To remove mucus plugs or objects blocking an airway

Before the procedure

You will be asked not to eat or drink for several hours. Tell your doctor about blood-thinning medicines, and arrange for someone to take you home.

During the procedure

A local anaesthetic spray numbs the nose and throat, and sedation is usually given. The procedure usually takes 20 to 40 minutes.

After the procedure

Do not eat or drink until the numbness wears off. A sore throat, cough or slight fever for a day is common.

Risks

Bronchoscopy is generally safe. Rare risks include bleeding after a biopsy, low oxygen levels during the procedure and a collapsed lung.

At KIH

KIH's pulmonology service examines the airways using a flexible bronchoscope and also offers image-guided sampling of lung masses and ultrasound-guided drainage of pleural fluid.
