Did you say you want to look inside your chest? Let's talk about mediastinoscopy!

Sometimes, when doctors suspect that there is something wrong with your chest, that is, the area between your lungs, they will order a special test to find out exactly what it is. That is the test called a mediastinoscopy. The name may sound a little strange, but today we will talk clearly about many things, such as what happens with this, why it is done, how it is done, and whether you should be afraid of it. If you too have been told by a doctor that you need to have such a test, I am sure that this story will be very important to you.

What is this mediastinoscopy?

Simply put, a mediastinoscopy is a surgical procedure that allows your doctor to get a better look at the middle of your chest, the space between your lungs (which we medically call the mediastinum) . This area is home to important organs like your heart, your esophagus , and your trachea .

So how do you look at this? Doctors use a special instrument called a mediastinoscope . It's like a thin tube. It has a small light and a camera at one end. The doctor can see what the camera sees on a monitor. Another special feature of this instrument is that it can take a tissue sample , a lymph node (these are parts of the system that fights disease in our body), or anything else that's unusual, like a lump, and send it to the lab.

What is the difference between Mediastinotomy and Mediastinoscopy?

You may have heard of another term, mediastinotomy. Both of these procedures involve looking into the area in the middle of the chest called the mediastinum and taking samples from there. Both of these procedures are also used to find out if a disease like cancer has spread.

But there is a slight difference. In a mediastinotomy, a small opening is made directly in the chest, which means a cut is made in the skin to create a passageway. In a mediastinoscopy, a very small incision is made and the tube called the mediastinoscope is inserted. Although a mediastinotomy allows the surgeon to see a little more space, the incision is a little larger and the healing time is a little longer. In a mediastinoscopy, the incision is smaller, so healing occurs more quickly.

Why is a mediastinoscopy performed?

There may be several reasons why a doctor might ask you to have this test.

• The main reason is to check carefully to see if there is any problem in the space between the two lungs (mediastinum).
• Lymph nodes are taken and checked for cancer. Sometimes this is also done to see if cancer from elsewhere has spread to these lymph nodes.
• If you have cancer in your lungs, thymus gland (also a small gland in the upper chest), or esophagus, this test can help determine the severity, or stage, of the cancer .
• Although not often, this can sometimes be done if you suspect you have an infection in the lungs .
• It can also detect diseases such as lymphoma, sarcoidosis (a disease that causes small swellings in various parts of the body), or mesothelioma (a type of lung cancer) .

Are there people who don't want to take this test?

Yes, not everyone can have a mediastinoscopy. Some people may not be suitable for this procedure. For example:

• People who have an inoperable tumor that is too large to be removed with surgery.
• People who have had a mediastinoscopy before (as it can be a bit more complicated the second time around).
• People who have had radiation therapy to the chest area (because the tissue in that area may have changed).

For reasons like these, it is up to the doctor to decide whether this test is right for you or not.

Who performs this mediastinoscopy?

This is done by a cardiothoracic surgeon or a general surgeon . It is also done in an operating room . Because, if something happens suddenly, such as more bleeding than expected, you need to be prepared to go to a major surgery to control it (that is, a surgery that cuts the middle bone of the chest - sternotomy , or a surgery that cuts between the ribs - thoracotomy) . Therefore, this is done in a place with such facilities.

How do you prepare for this?

Once you have been scheduled for a mediastinoscopy, there are a few things you need to prepare for a few days in advance.

• You will need to have the tests your doctor orders, which may include a chest X-ray, a CT scan, and a pulmonary function test .
• If you are taking blood thinners, your doctor will probably tell you to stop taking them a few days before the test . Ask your doctor for specific instructions.
• You will be asked to stop eating and drinking for a few hours before the test. This means you need to have an empty stomach.

Your doctor or nurse will explain all of this to you. It is very important to follow those instructions exactly.

Is this a same-day test?

Yes, most of the time you can go home the same day as your mediastinoscopy (outpatient procedure) . But before you go home, your doctor will check to see if you can do these things:

• Can you walk without help?
• Can you drink liquids like water ?
• Can you pee normally?
• Can you control your pain ? (That is, has the pain been reduced by the medication you are taking?)

If these things are okay, I'll let you go home.

How exactly is this mediastinoscopy performed?

Now let's see how to do this test step by step.

1. First, you will be given general anesthesia . This means that you will be completely asleep and will not feel anything during the entire procedure. This medication is given through a cannula placed in a vein in your arm.

2. Then a breathing tube is placed through your throat . This means that a machine will do your breathing during the test.

3. Next, the surgeon will make a very small incision, about an inch long, just above your chest, just below your neck.

4. Through that incision , the instrument called the mediastinoscope that I mentioned earlier is inserted.

5. Then slowly take it to the place you want to see.

6. Using the small tools on the device, samples can be taken from lymph nodes or other areas that seem abnormal, or even a small lump can be completely removed.

7. When the work is finished, the mediastinoscope is removed.

8. Cover that small cut with either dissolvable thread or an adhesive plaster.

9. Then you will be woken up from the anesthesia and the breathing tube will be removed.

Imagine, all this happens while you're sound asleep. So you don't feel anything.

How long will this take?

A mediastinoscopy usually takes about an hour to perform. However, sometimes it can take longer if the doctor needs to look a little deeper, take more samples, or if a sudden complication (such as bleeding) occurs and requires major surgery, such as the aforementioned sternotomy or thoracotomy, to control it.

What is the recovery time like after the test?

You will still feel a little sleepy for a few hours after you wake up from the anesthesia. This is normal. If you are not in too much pain after the test, a family member or friend can drive you home. You will not be able to drive that day because you have been given anesthesia.

Your mouth and throat will feel a little numb for a few hours. This is because of the breathing tube. For your safety, the doctors will not let you eat or drink until the numbness subsides. The next day, you may have a cough, hoarseness, a sore throat, and some pain at the incision site . These will subside in a few days.

Sometimes, after the test, you may also have a chest X-ray to make sure there are no problems with your lungs.

Is this painful?

Yes, there may be some pain where the test was done. So you will need to take pain medicine for a few days. The doctor will prescribe the necessary medicine for you. If you take the medicine at the right time, the pain can be controlled to a great extent.

What are the risks?

Most of the time, a mediastinoscopy does not cause any major complications. However, very rarely, some people may experience the following:

• Pneumonia (infection of the lungs).
• Pneumothorax (a lung that fills with air and becomes smaller than normal. This may require a small tube to be inserted to remove the air.)
• Bleeding. (Most of the time this is minor, but rarely it can be severe enough to require surgery.)
• Infected wound.

If we talk about the risk of death in this case, it is a very small amount, about 0.09 percent. That means that less than one in ten thousand people who undergo this test (about nine in ten thousand) has such a serious risk. So there is nothing to worry about. However, since there is a small risk with any surgical procedure, it is good to be aware of that as well.

What is the most common complication?

Bleeding is a slightly more common complication than other complications, but it is usually manageable.

What are the results like? What do they tell us?

The information obtained after the biopsy sample taken during your mediastinoscopy is sent to the laboratory for testing will help your doctor determine the stage of your cancer. The stage of your cancer is how large the tumor is and whether it has spread to nearby areas or to distant areas. This information will help your doctor decide what treatment is best for you.

How long does it take to know the results?

It can take a few days for the tissue samples to be analyzed in the lab. Then, if it is confirmed that you have cancer, the doctor will need some more time to develop a treatment plan that best suits you based on the results. So you will need to be patient until you get the results.

When do you need to call the doctor?

If you experience any of the following symptoms after you return home, call your doctor immediately or go to the nearest hospital.

• If chest pain increases, or if new chest pain occurs.
• If you get a bad fever.
• If it's hard to breathe, if it's like a fever.
• If the incision site is very red, swollen, and pus is coming out.

Don't ignore things like this.

So, what are the most important things we need to remember from this?

Okay, so I think you now have a better understanding of the mediastinoscopy we talked about today.

Remember, this is a safe test in most cases. A doctor will order this to get a clear understanding of your condition and give you the best treatment you need.

If you have any questions or concerns about this, don't be afraid to talk to your doctor. They will explain everything to you. The most important thing is to follow the doctor's instructions exactly. Then everything will go well. I wish you a speedy recovery!
