How It Is Done
A liver biopsy is done by a
gastroenterologist,
hepatologist, or
radiologist in a clinic or a hospital. A liver biopsy
is often done by a radiologist using ultrasound, a CT scan, or
magnetic resonance imaging (MRI) to help guide the
biopsy needle. When cirrhosis of the liver or a cancer is suspected, a liver
biopsy may be done during a
laparoscopy.
You will need to take off all or most of your clothes. You
will be given a cloth or paper gown to use during the test.
Before the test, you may be given a sedative through a vein
(IV) in your arm. The
sedative will help you relax and remain still. During the test, you will lie on
your back with your right arm resting under or above your head and your head
turned to your left. Your doctor may tap on your chest and belly to find your liver or he or she may use ultrasound.
Your doctor will mark a spot between two of your right lower
ribs where the biopsy needle will be inserted. The site will be cleaned with a special soap and draped with sterile towels. The doctor will give
you a
medicine (local anesthetic) to numb the area where the biopsy
needle will be inserted.
You may be asked to take a deep breath, blow all the air out, and
then hold your breath while the biopsy needle is being inserted and withdrawn.
This will take only a few seconds. Holding your breath lowers the chance that
the needle will go in your lung since the lungs are very close to the liver. It is important to
remain still during the few seconds it takes for the doctor to collect the
tissue sample. The doctor may take another tissue sample from the same spot,
but from a different angle.

placement
of the liver biopsy needle

As soon as the doctor removes the needle, you can breathe normally.
A bandage will be put on the puncture site. The test generally takes
15 to 30 minutes.
You will rest in bed and lie on your right side for
2 to 6 hours after the test. Your pulse, blood pressure, and temperature will
be checked often after the biopsy.
You can go home if you have no problems after the test. You
may eat your regular diet, but do not take ASA or
anti-inflammatory medicines for a week after the biopsy. You may do
your regular activities, but do not do strenuous activities or heavy
lifting until your doctor says it is safe.
