How the Test is Performed
This procedure is done in the hospital. You will be given
A small surgical cut is made just above the breastbone. A device called a mediastinoscope is inserted through this cut and gently passed into the mid-part of the chest.
Tissue samples are taken of the lymph nodes around the airways. The scope is then removed and the surgical cut is closed with stitches.
A chest x-ray will often be taken at the end of the procedure.
The procedure takes about 60 to 90 minutes.
How to Prepare for the Test
You must sign an informed consent form. You will not be able to have food or fluid for 8 hours before the test.
How the Test will Feel
You will be asleep during the procedure. There will be some tenderness at the site of the procedure afterward. You may have a sore throat.
Most people can leave the hospital the next morning.
In most cases, the result of the 活组织检查 is ready in 5 to 7 days.
Why the Test is Performed
This procedure is done to look at and then 活组织检查 lymph nodes or any other abnormal growths in the front part of the mediastinum, near your chest wall.
- The most common reason is to see if lung cancer (or another cancer) has spread to these lymph nodes. This is called staging.
- This procedure is also done for certain infections (tuberculosis, sarcoidosis) and
autoimmune disorders .
正常的结果
Biopsies of lymph node tissues are normal and do not show signs of cancer or infection.
What Abnormal Results Mean
Abnormal findings may indicate:
霍奇金病 肺癌 淋巴瘤 或者其他肿瘤结节病 - The spread of disease from one body part to another
肺结核
风险
There is a risk of puncturing the esophagus, trachea, or blood vessels. In some cases, this can lead to bleeding that can be life threatening. To fix the injury, the breastbone would need to be split and the chest opened.
