Quick answer. A bronchoscopy is a test in which a respiratory physician passes a thin camera through the nose or mouth to look inside your airways, take samples and sometimes treat problems. It is usually done with sedation as a day procedure and is generally very safe.
A bronchoscopy is a procedure that lets a respiratory physician look directly inside your windpipe and the airways of your lungs using a thin, flexible tube with a camera and light at the tip. In Singapore it is commonly used to investigate a persistent cough, an abnormal chest X-ray or CT scan, coughing up blood, or to take a biopsy. It is one of the most useful tools a lung specialist has for diagnosing problems that scans alone cannot explain.
If your doctor has recommended a bronchoscopy, it is natural to feel anxious. This guide explains why a bronchoscopy is ordered, how the procedure is done, what sedation and aftercare involve, the small risks, and a typical market cost range in Singapore. It is a guide only – your own care should always follow your specialist’s advice.
At a glance
| Aspect | What to expect | Notes |
|---|---|---|
| Why it's done | Persistent cough, abnormal scan, coughing blood, biopsy | To diagnose or sometimes treat airway problems |
| Sedation | Usually light or moderate sedation; local anaesthetic spray | You are relaxed and drowsy, often not fully asleep |
| Duration | The scope itself often takes around 20-40 minutes | Plan for a few hours including recovery |
| Setting | Usually a day procedure | You go home the same day in most cases |
| Recovery | Sore throat and mild hoarseness for a day or so | No driving on the day if sedated |
What is a bronchoscopy?
A bronchoscopy is an examination of the airways – the windpipe (trachea) and the branching tubes (bronchi) that carry air into the lungs. A respiratory physician passes a flexible bronchoscope, a thin tube with a camera, through the nose or mouth, down the throat and into the airways. Images are displayed on a screen so the doctor can inspect the lining of the airways in detail.
Most bronchoscopies in Singapore use a flexible scope under sedation and are done as a day procedure. A bronchoscopy is both a diagnostic test (to find the cause of a problem and take samples) and, in some situations, a treatment (for example, to remove mucus plugs or a foreign object). It is a common, well-established procedure performed by lung specialists.
Why a bronchoscopy is ordered
Your respiratory physician may recommend a bronchoscopy to investigate or treat a range of airway and lung problems. Common reasons include:
- A persistent cough that has not settled with usual treatment
- An abnormal area on a chest X-ray or CT scan that needs closer assessment
- Coughing up blood (haemoptysis)
- Taking a biopsy or sampling cells and fluid to look for infection, inflammation or cancer
- Investigating an unexplained lung infection
- Removing mucus plugs, secretions or an inhaled foreign object
The aim is to get information that scans and blood tests alone cannot provide, so your doctor can make an accurate diagnosis and plan treatment.
The procedure & sedation, step by step
Knowing what happens can make the test feel less daunting. A typical flexible bronchoscopy follows these steps:
- Before: you will usually be asked to fast (no food or drink) for several hours beforehand. Tell your doctor about your medicines, especially blood thinners.
- Numbing: a local anaesthetic is sprayed into the nose and throat to numb them, and oxygen and monitoring are set up.
- Sedation: most patients are given light or moderate sedation through a vein so they feel relaxed and drowsy. You are usually breathing on your own throughout.
- The scope: the thin bronchoscope is passed gently through the nose or mouth into the airways. The doctor inspects the lining and may take samples, washings or biopsies.
- Duration: the procedure itself often takes around 20 to 40 minutes, though the exact time varies.
You may cough a little as the scope passes, but the numbing and sedation make it tolerable for most people.
Aftercare & recovery
After a bronchoscopy you will be monitored in a recovery area until the sedation wears off. Most people go home the same day. What to expect afterwards:
- A sore throat, mild hoarseness or a slight cough for a day or two
- You must not eat or drink until the throat numbness has fully worn off (to avoid choking), usually a couple of hours
- If you were sedated, do not drive, operate machinery or sign important documents for the rest of the day, and arrange for someone to take you home
- Biopsy results typically take several days; your doctor will arrange follow-up
Most people are back to normal activities the next day. Follow the specific instructions your clinic gives you.
Risks & typical cost in Singapore
Bronchoscopy is generally very safe, but as with any procedure there are small risks, which your doctor will explain. These can include a mild sore throat, a temporary drop in oxygen, minor bleeding (especially after a biopsy), and rarely a small air leak around the lung (pneumothorax) or infection.
Cost in Singapore varies widely depending on whether it is done in a public (restructured) or private hospital, the type of sedation, and whether biopsies or extra procedures are performed. As a rough guide, the typical market range for a diagnostic bronchoscopy in Singapore is often in the region of about S$1,500 to S$5,000 or more, with biopsies, laboratory tests and hospital charges adding to the total. This is a general range only, not a quote. For an accurate figure, ask your hospital or specialist for an itemised estimate, and check whether MediSave or insurance may apply to part of the cost.
When a respiratory physician orders it & which specialist to see
A bronchoscopy is ordered and performed by a respiratory physician (lung specialist), usually after a consultation and imaging. If you have been advised to have one, it is because your specialist needs a direct look at your airways or a tissue sample to make the right diagnosis.
Some symptoms should never wait for an elective test. Seek urgent care or call 995 if you have severe breathlessness, are coughing up large amounts of blood, or have chest pain with difficulty breathing. These need emergency assessment rather than a planned procedure.
If you have a persistent cough, an abnormal scan or are coughing up blood, see a respiratory physician. You can find one through our directory of the best respiratory physicians in Singapore.
