Transbronchial lung biopsy: procedure, safety, side effects, and benefits

Definition

What is a transbronchial biopsy?

Transbronchial biopsy involves removing a small piece of tissue from the lung. Transbronchial biopsy is an effective way to find out problems with the lungs.

When do I need to have a transbronchial biopsy?

You will be asked by your doctor to do a lung biopsy if needed to diagnose your disease. A lung biopsy is usually done to:

diagnose certain lung conditions, such as sarcoidosis or pulmonary fibrosis. In certain cases, a lung biopsy is performed for severe pneumonia, especially if the diagnosis is unclear

diagnose lung cancer

evaluate for abnormalities that show up on the results of other tests, such as X-rays or CT scans.

A lung biopsy is usually done if other tests have not identified the cause of the lung problem.

Precautions & warnings

What do I need to know before undergoing a transbronchial biopsy?

A lung biopsy is generally a safe procedure. The risk depends on whether you have lung disease and how severe it is. If you have breathing problems, your breathing may get worse shortly after the biopsy.

In addition to a transbronchial biopsy, X-rays or scans can show lung problems.

Process

What should I do before undergoing a transbronchial biopsy?

You will be given preoperative instructions, such as whether you are allowed to eat before the operation.

What is the transbronchial biopsy process?

The doctor will provide sedatives to help you relax. Transbronchial biopsy generally lasts less than 30 minutes. The doctor will insert a flexible telescope (bronchoscope) through your nose and into your lungs. The doctor will use a bronchoscope to check the bronchi. Then the forceps will be inserted into the lungs to take a sample of lung tissue.

What should I do after having a transbronchial biopsy?

You are allowed to go home after you have recovered from the effects of sedatives. The medical team will explain the results of the transbronchial biopsy and discuss with you about any further treatment and actions you need. You can return to work the next day unless advised otherwise. Usually you are prohibited from traveling by plane for 1 month.

Complications

What complications can occur?

Transbronchial lung biopsy is performed under light sedatives or local anesthesia. Complications can include, but are not limited to:

pneumothorax or air trapped in the pleural cavity that causes the lungs to collapse

bleeding in the lungs

infection

If you are pregnant, make sure you inform your doctor.
