A liver biopsy can be performed a few different ways: a needle can be inserted through the skin, and take a sample of the liver; during abdominal surgery, a piece of the liver may be removed; through blood vessels, a sample of the liver may be taken. the live sample would then be taken to be studied under a microscope.
There are three kinds of lymph node biopsy. Sentinel lymph node mapping and biopsy is a promising new technique that is discussed in its own entry. Fine needle aspiration (FNA) biopsy, often just called needle biopsy, is done when.
No particular preparation is necessary for a needle biopsy. For an open biopsy, patients need standard pre-operative blood tests and other tests to evaluate general health. The doctor should be informed about any medications.
A Doctor Who specializes in nuclear medicine first numbs the area around the tumor with a local anesthetic and then injects the radioactive technetium. He or she usually injects a blue dye as well.
Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope.
The lymphatic system is made up of lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell, produce more white blood cells, and attempt to trap the organisms that are causing the infection. The lymph nodes also try to trap cancercells.
Alternative NamesBiopsy - lymph nodes
How the test is performedThe test is done in an operating room in a hospital, or at an outpatient surgical facility. There are two ways the sample may be obtained:
A needle biopsy involves inserting a needle into a lymph node. You will lie on the examination table. The biopsy site will be cleansed, and the health care provider will inject a local anesthetic (numbing medication) into the area. The biopsy needle is then inserted into the node, and a sample is removed. Pressure is applied to the site to stop the bleeding, and a bandage is applied.
An open biopsy is surgery to remove all or part of the lymph node. You will lie on the examination table. You may be given a medicine to calm you and make you sleepy, if you prefer. The biopsy site will be cleansed, and the health care provider will inject a local anesthetic (numbing medication) into the area. (Occasionally, general anesthesia is used, which means you are asleep and pain-free.) A small surgical cut is made, and the lymph node or part of the node is removed. The area is closed with stitches and a bandage is applied.
The sample is then sent to the laboratory for examination.
How to prepare for the testTell your health care provider:
You must sign a consent form.
How the test will feelWhen the local anesthetic is injected, there will be a prick and a mild stinging. The biopsy site will be sore for a few days after the test.
Why the test is performedThe test is used to help determine the cause of swollen glands. It may be done to find out if a lymph node tumor is cancerous (malignant) or noncancerous (benign).
Normal ValuesSwollen lymph nodes may be caused by a number of conditions, ranging from very mild infections to cancer.
What abnormal results meanAbnormal results may be due to many different conditions, from very mild infections to cancer.
For example, enlarged lymph nodes may be due to:
What the risks areA lymph node biopsy is the removal of lymph node tissue for examination under a microscope.
The lymph nodes are small glands that make white blood cells (lymphocytes), which fight infection. Lymph nodes may trap the germs that are causing an infection. Cancer can spread to lymph nodes.
Alternative NamesBiopsy - lymph nodes; Open lymph node biopsy; Fine needle aspiration biopsy; Sentinel lymph node biopsy
How the test is performedA lymph node biopsy is done in an operating room in a hospital, or at an outpatient surgical facility. The biopsy may be done in different ways.
A needle biopsyinvolves inserting a needle into a lymph node.
A needle biopsy may also be done during mediastinoscopy or bronchoscopy.
An open biopsy is surgery to remove all or part of the lymph node.
For some cancers, a special way of finding the best lymph node to biopsy is used. This is called sentinal lymph node biopsy, and it involves:
The sample is then sent to the laboratory for examination.
How to prepare for the testTell your health care provider:
Your doctor may ask you to:
You must sign a consent form.
How the test will feelWhen the local anesthetic is injected, you will feel a prick and a mild stinging. The biopsy site will be sore for a few days after the test.
After an open biopsy, the pain is mild and you can easily control it with an over-the-counter pain medication. You may also notice some bruising or fluid leaking for a few days. The wound should heal in 10 - 14 days. During this time, avoid any type of intense exercise or heavy lifting.
Why the test is performedThe test is used to diagnose cancer or an infection:
The results of the biopsy help your doctor decide on further tests and treatments.
Normal ValuesIf a lymph node biopsy does not show any signs of cancer, it is more likely that other lymph nodes nearby are also cancer-free. This information can help the health care provider decide about further tests and treatments.
What abnormal results meanAbnormal results may be due to many different conditions, from very mild infections to cancer.
For example, enlarged lymph nodes may be due to:

A lymph node biopsy is a procedure in which all or part of a lymph node is removed and examined to determine if there is cancer within the node.
During the biopsy, a cylindrical piece of bone and marrow fluid is removed. They are generally taken out of the hipbone.

Women who are pregnant should inform their doctor before a lymph node biopsy, although pregnancy will not affect the results.
This will vary depending upon what the lymph node biopsy is for. Sometimes all or part of just one node is collected; other times several nodes may be sampled.

Use CPT 38505 for superficial needle biopsy of lymph nodes.
The difference between incision and excision of lymph nodes is very simple. The incision of a lymph node is when the biopsy only takes part of the lymph node during surgery. The excision of the lymph node is when the whole lymph node is removed.

A new technique called sentinel lymph node mapping and biopsy often eliminates the need for removing some or all lymph nodes by testing the first lymph node for cancer.
It depends as to which organ drainage the lymph node has. If there is only one lymph node needed say for histological test or biopsy only one incision is fine. But i think, generally it takes only one incision.

the discovery that the human lymphatic system can be mapped with radioactive dyes, and that the lymph node(s) closest to a tumor serve to filter and trap cancer cells.
It all depends on what organ is affected. Ask your doctor.
There are few risks associated with lymph node biopsy. The main risks are excessive bleeding (usually only in people with blood disorders) and allergic reaction to general anesthesia (rare). Occasionally the biopsy site becomes infected.
