Mediastinoscopy: Before Your Procedure

What is mediastinoscopy?

Mediastinoscopy (say "mee-dee-yass-tuh-NAW-skuh-pee") is a procedure that looks at the space behind your breastbone and between your lungs. This area is called the mediastinum (say "mee-dee-ya-STY-num").

During the procedure, a small cut (incision) is made in the neck just above the breastbone or on the left side of the chest next to the breastbone. Then a thin lighted scope (mediastinoscope) is inserted through the incision. The scope lets the doctor look around inside that space. This procedure is done to look for problems such as infection, inflammation, or cancer. A tissue sample (biopsy) can be collected through the scope. The sample can be examined under a microscope for problems.

This procedure usually takes about an hour.

How do you prepare for the procedure?

Procedures can be stressful. This information will help you understand what you can expect. And it will help you safely prepare for your procedure.

Preparing for the procedure

• Your doctor may order certain blood tests, such as a complete blood count or clotting factors, before your procedure.
• Understand exactly what procedure is planned, along with the risks, benefits, and other options. Be sure to ask what may be done, such as lymph nodes being biopsied or removed, for each possible biopsy result.
• Tell your doctor ALL the medicines, vitamins, supplements, and herbal remedies you take. Some may increase the risk of problems during your procedure. Your doctor will tell you if you should stop taking any of them before the procedure and how soon to do it.
• If you take aspirin or some other blood thinner, ask your doctor if you should stop taking it before your procedure. Make sure that you understand exactly what your doctor wants you to do. These medicines increase the risk of bleeding.
• Make sure your doctor and the hospital have a copy of your advance directive. If you don’t have one, you may want to prepare one. It lets others know your health care wishes. It’s a good thing to have before any type of surgery or procedure.
• Be sure you have someone to take you home. Anesthesia and pain medicine will make it unsafe for you to drive or get home on your own.

What happens on the day of the procedure?
