Mediastinoscopy with biopsy
A biopsy is a procedure that extracts cells or tissues in your body. A doctor called a pathologist examines the cells or tissues under a microscope to check for damage or disease. The pathologist can also do other tests to these cells.
Biopsies can be taken from any part of the body. In the majority of cases, a biopsy is the only test that can indicate safely if a suspicious area has cancer. But biopsies are performed by many other reasons also.
There are different types of biopsies. A needle biopsy with a needle tissue removed from the involved area. Other biopsies that require surgery.
The mediastinoscopy with biopsy is a procedure in which a lighted instrument (mediastinoscope) is inserted into the space in the chest between the lungs (mediastinum). Removed tissue (biopsy) of any abnormal growth or lymph node.
How the test is performed
This procedure is done in the hospital. Be charged general anesthesia so that you are asleep and feel no pain. It is placed a tube (endotracheal tube) into the nose or mouth to help him breathe.
A small surgical incision above the breastbone is. A device called a mediastinoscope through this cut is inserted and is gently passed into the middle part of the thorax.
Take tissue samples from the lymph nodes around the Airways. The mediastinoscope is removed and the surgical incision is closed with stitches.
Frequently will take an x-ray of the chest at the end of the procedure.
The procedure takes about 60 to 90 minutes.
You must sign an authorization. You can not consume any food or drink for 8 hours before the test.
What the test will feel
You will be asleep during the procedure. Then you will have some sensitivity at the biopsy site. You may have sore throat.
The majority of persons can leave the hospital the next morning.
In the majority of cases, the result of the biopsy is ready in 5–7 days.
Reasons why the test is performed
This procedure is done to examine and then take a biopsy of the lymph nodes or any abnormal growth in the front part of the mediastinum, near the chest wall.
The most common reason is to see if lung cancer (or other cancer) has spread to the lymph nodes. This is called staging.
This procedure is also done for certain infections (tuberculosis, sarcoidosis), and autoimmune disorders.
Biopsies of the lymph tissues are normal and do not show signs of cancer or infection.
What abnormal results mean
Abnormal findings may indicate:
Lymphoma or other tumors
Disease spread from one part of the body to another
There is a risk of perforating the esophagus, trachea, or blood vessels. In some cases, this can lead to bleeding which can be life–threatening. To correct the injury, the sternum should be divided and open chest.
