General
Stats:
- Description: Infection,
inflammation, and tumors can affect any organ within the abdomen. Sometimes
an abnormality is identified to involve the liver, pancreas, lymph nodes,
or kidneys and the exact cause may not be apparent. In these situations
a biopsy of the affected organ can be helpful in leading to the cause and
treatment of the disease process. A Radiologist or Gastroenterologist performs
the test in a hospital. Sometimes CT scan or ultrasound guides the biopsy
needle. A Pathologist interprets the results. The test takes 15-60 minutes
to perform.
- Discomfort - Moderately
discomfort during needle insertion.
- Results - 2-3 days.
- Risks of Procedure
- Main risk of test is bleeding. Other risk include injury to the organs
of the abdomen and infection.
- Average Cost - $$-$$$
- Other names
Liver biopsy, pancreatic biopsy, or fine needle biopsy.

- To identify cirrhosis
or hepatitis in the liver.

Procedure
- You are placed on
a table or x-ray table.
- After the site to
be biopsied is sterilized, a local anesthetic is injected.
- You may be asked
to exhale completely and hold your breath to reduce the risk of a puncturing
the lung.
- A needle is inserted
into the organ to be biopsied. A CT scan or ultrasound may be used to guide
placement of the needle.
- The needle is inserted
quickly and then withdrawn. The tissue inside the needle is removed for
analysis.
- Sometimes several
insertions of the needle are performed to insure that adequate tissue is
obtained or to sample different areas

After the Procedure
- A pressure dressing
is applied to the puncture site to control bleeding.

in a recovery area until it is certain you have no complications. You may
be monitored for up to 4 hours if a liver biopsy was performed.

to have limited activity for 1 day.
- Pain is to be expected

Factors affecting results
- Small areas of abnormality
can be difficult to sample adequately.

Advantages
- Tissue is obtained
for analysis when the cause of an abnormality is not apparent from other
tests.
- The test can sometimes
avoid the need for surgery.

Disadvantages
- The test is painful
and invasive.
- Only small tissue
samples are obtained.
