Liver Biopsy
The consultant will always take a medical history and perform a
physical exam. Blood studies, known as liver function tests (LFT),
give an overview of the health of the liver. If LFT results are
persistently abnormal, the consultnat will then perform additional
medical tests to determine the exact cause of the problem sometimes
a liver biopsy helps answer this question.
A biopsy is a tiny sample of body tissue - in this case, liver tissue.
The tissue is prepared and stained in a laboratory to be viewed
under a microscope.
Sometimes, an ultrasound or echo machine is used to identify the
best location to make the biopsy. The patient lies on their back
or slightly to the left side. That area of the skin where the biopsy
will be done is carefully sterilised. Then, a local anesthetic agent
is used to numb the skin and tissue below. A specially designed
thin needle is inserted through the skin. At this point, the patient
is told how to breathe. The needle is advanced into and out of the
liver. This takes only 1 or 2 seconds. A slender core of tissue
is removed with the needle, and is then processed through the laboratory.
The entire procedure from start to finish lasts only 15 to 20 minutes.
The patient is kept at rest for several hours following the exam.
Medical personnel check the heart rate and blood pressure during
this time. There may be some discomfort in the chest or shoulder,
however, this is usually temporary. Medication is available for
this discomfort, if needed. Before being discharged, the patient
is given instructions about returning to normal activities and about
eating. Activity is usually restricted for a day or so after the
biopsy. However, the procedure does not require a long recovery
period.
In most instances, a liver biopsy is obtained quickly with no problems.
Occasionally, some discomfort in the right side or shoulder is experienced
and internal bleeding can sometimes occur as well as a leak of bile
from the liver or gallbladder. These problems are rare and can usually
be handled without the need for surgery.
A liver biopsy is a simple, rapid method of obtaining a sample of
liver for analysis. It provides important information for evaluating
and treating liver disorders. While some complications can occur,
they are unusual. The benefits of the exam always outweigh the risk.
