Liver Biopsy Overview

Written by FoundHealth.


This is a procedure to obtain a sample of your liver tissue.

What to Expect

Prior to Procedure

Your doctor may do the following:

  • Physical exam
  • Blood tests
  • Ultrasound—a test that uses sound waves to examine the liver

Before your biopsy:

  • Avoid eating or drinking for 8-12 hours.
  • Talk to your doctor about your medicines. You may be asked to stop taking some medicines up to one week before the procedure, like:
  • Anti-inflammatory drugs (eg, aspirin )
  • Blood thinners, such as clopidogrel (Plavix) or warfarin (Coumadin)
  • Arrange for someone to drive you home after the biopsy.


Local anesthesia—just the area that is being operated on is numbed; given as an injection and may also be given with a sedative

Description of the Procedure

There are different techniques to do a liver biopsy, including:

  • Conventional liver biopsy
  • Laparoscopic liver biopsy (done when the biopsy needs to be taken from a very specific area of the liver)
  • Transvenous liver biopsy (done if your blood clots poorly or you have a lot of fluid in your abdomen)

Conventional Liver Biopsy

You will lie on your back with your right hand behind your head. The doctor might use an ultrasound or CT scan to help guide the placement of the needle. The skin will be cleaned. Next, the doctor will inject medicine to numb the area. The doctor will make a small incision. You will need to exhale and hold your breath while the needle is inserted. Sometimes, the needle will need to be inserted several times. After the procedure, your doctor will bandage the area. You will lie on your right side for at least two hours.

Laparoscopic Liver Biopsy

Your doctor will make a tiny incision. She will pass a long tool with a camera on the end into your abdomen in the area of the liver. The scope will send images of the liver to a TV screen. Your doctor will make other incisions to pass other tools. With these tools, she will remove samples of the liver.

Transvenous Liver Biopsy

Your doctor will thread a tiny flexible tube into a vein in your neck or groin. This tube will be threaded all the way into the veins in your liver. Your doctor will pass a biopsy needle through the tube to get a biopsy sample.

Immediately After Procedure

You will lie on your right side for at least two hours.

How Long Will It Take?

About 15-20 minutes

Will It Hurt?

You will have mild pain or cramping at the biopsy site. You may also have pain in the right shoulder. The pain should last for less than 30 minutes.

Postoperative Care

When you return home after the procedure, do the following to help ensure a smooth recovery:

  • If a sedative was given, do not drive for at least 24 hours.
  • Rest the remainder of the day.
  • Do not exercise or lift heavy objects for at least a week. Ask your doctor when you can resume normal activities.
  • Eat your normal diet.
  • Ask your doctor when you can resume taking your medicines.
  • Be sure to follow your doctor's instructions .

The results will take 1-4 weeks. You and your doctor will discuss the results.
