Bronchoscopy is a specialized procedure that allows doctors to look directly inside the airways of the lungs. It is done using a thin, flexible or rigid tube called a bronchoscope, which has a light and camera at the tip. This tube is passed through the nose or mouth, down the throat, and into the windpipe and bronchial tubes. Through the bronchoscope, doctors can see the lining of the airways, take samples, remove foreign bodies, place stents, or perform other treatments.
Bronchoscopy is an important tool in diagnosing and treating many lung and airway conditions. It is used when chest X-rays or CT scans are not enough to explain symptoms such as persistent cough, blood in sputum, recurrent infections, or unexplained lung shadows. It is also used to treat conditions like airway blockages, bleeding, or collapsed lung segments.
What is Bronchoscopy?
Bronchoscopy is a procedure in which a doctor examines the inside of the airways using a bronchoscope. The bronchoscope is a long, thin tube with a light and camera. It allows the doctor to see the trachea, bronchi, and smaller airways on a screen.
This can be done as a diagnostic procedure to find the cause of symptoms, or as a therapeutic procedure to treat a problem in the airway.
During bronchoscopy, the doctor can:
- Inspect the airway lining for inflammation, tumors, or narrowing.
- Take small tissue samples or biopsies from suspicious areas.
- Collect fluid or mucus samples for testing.
- Remove foreign objects stuck in the airway.
- Clear mucus plugs causing blockage.
- Place stents to keep narrowed airways open.
- Control bleeding in the airway.
- Perform laser treatment or other interventions in selected cases.
Types of Bronchoscopy
There are two main types of bronchoscopy, each with specific uses.
Flexible Bronchoscopy
- Uses a thin, flexible tube that can bend easily.
- Passed through the nose or mouth.
- Usually done with local anesthesia and mild sedation.
- Most common type used for diagnosis and many treatments.
- Allows examination of smaller airways.
- Suitable for biopsy, brushing, washing, and some therapeutic procedures.
Rigid Bronchoscopy
- Uses a straight, rigid metal tube.
- Passed through the mouth under general anesthesia.
- Allows better control of the airway and breathing during complex procedures.
- Used for removing large foreign bodies.
- Used for controlling severe bleeding in the airway.
- Used for placing larger stents or performing laser treatments.
- Often used in emergency situations or complex airway interventions.
The choice between flexible and rigid bronchoscopy depends on the reason for the procedure, the patient’s condition, and the expertise of the medical team.
Indications for Bronchoscopy
This is recommended when there is a need to directly visualize the airways or obtain samples from the lungs.
Common reasons for diagnostic bronchoscopy
- Persistent cough that does not improve with treatment.
- Blood in sputum or coughing up blood.
- Recurrent chest infections in the same area of the lung.
- Unexplained lung shadow or mass on X-ray or CT scan.
- Suspected lung cancer or airway tumor.
- Evaluation of airway narrowing or stricture.
- Collection of samples for infection, including tuberculosis or fungal infection.
- Assessment of interstitial lung disease.
- Evaluation of unexplained wheezing or stridor.
Common reasons for therapeutic bronchoscopy
- Removal of foreign body from the airway.
- Clearance of mucus plugs causing lung collapse.
- Control of bleeding in the airway.
- Placement of airway stents to keep narrowed airways open.
- Laser treatment or cautery for tumors blocking the airway.
- Drainage of lung abscess or infected fluid in selected cases.
- Assistance in difficult intubation or airway management.

Frequently Asked Questions (FAQs)
Is bronchoscopy painful?
Most patients do not find bronchoscopy very painful. Local anesthesia and sedation are used to reduce discomfort. You may feel pressure, coughing, or a gagging sensation, but the team will adjust sedation to keep you comfortable.
How long does bronchoscopy take?
Flexible bronchoscopy usually takes 15 to 45 minutes, depending on the reason for the procedure. Rigid bronchoscopy or complex therapeutic procedures may take longer. Total time in the hospital may be several hours including preparation and recovery.
Will I be awake during bronchoscopy?
For flexible bronchoscopy, most patients are awake but sedated and relaxed. For rigid bronchoscopy, general anesthesia is used and you will be asleep. The type of anesthesia depends on the procedure and your condition.
Can I eat before bronchoscopy?
No, you must fast before bronchoscopy to reduce the risk of choking or aspiration. Usually, no solid food is allowed for at least 6 hours before the procedure. Follow the exact instructions given by your doctor.
Is bronchoscopy safe?
Bronchoscopy is generally safe when done by experienced doctors in a proper setting. Mild side effects like sore throat are common. Serious complications are rare but can include bleeding, infection, or lung collapse. Your doctor will explain your individual risk.
When will I get the results?
Some findings can be discussed immediately after the procedure. Biopsy and lab test results may take a few days to a week, depending on the tests done. Your doctor will schedule a follow-up to explain the results and next steps.
Can I go home the same day?
Most patients can go home the same day after flexible bronchoscopy once the sedation wears off. Some patients may need overnight observation, especially after rigid bronchoscopy or complex procedures. You should have someone to accompany you home.
