Liver Biopsy

What is it?

Removal of a tiny piece of liver tissue for analysis.

What is the purpose?

Many of the medications taken for various types of arthritis can damage the liver. If blood work shows some liver problems a biopsy can be used to determine the condition of the liver and what damage has been done.

Is there any special preparation?

There is no special preparation. You will be asked to sign a consent form and put on a hospital gown. An IV may be inserted to inject a sedative.

How is it done?

You may be sedated before the procedure. The area (lower right side of the chest or upper abdomen) will first be cleansed with an antiseptic such as betadine. The skin may be numbed with a "freeze" spray. A local anesthetic is injected with a needle. A special biopsy needle is then inserted into the liver. The needle sucks up a tiny sliver of liver tissue.

What happens afterwards?

Follow any instructions given by your doctor. Call your doctor if you notice any redness, swelling or bleeding at biopsy site.

What are the risks of this procedure?

There is always the risk of infection and bleeding with any invasive procedure.

Does it hurt?

It may uncomfortable or painful, but it is over very quickly.
