Has a doctor ever told you about a surgery to remove lymph nodes in the groin area? It's normal to feel a little scared and curious when they say that. So today, we'll talk about this surgery called `(Inguinal Lymph Node Dissection)`, that is, the removal of lymph nodes in the groin, in a simple way that you can understand. This will help you gain a better understanding of this.
First, let's see, what is Inguinal Lymph Node Dissection?
Simply put, a groin lymph node dissection is a surgical procedure to remove the lymph nodes (also known as the axilla) in your groin area, where your legs meet your lower abdomen. A doctor may decide to perform this type of surgery to see if cancer has spread to these lymph nodes from a nearby area of your body, or to stop cancer from spreading.
This surgery is called by other names, some call it ``Groin Dissection'', others call it ``Lymphadenectomy.'' No matter what the name, the procedure is the same.
So what are these inguinal lymph nodes?
Think about it, we have little checkpoints all over our bodies. These are what we call lymph nodes . Some people also call them ``lymph nodes.'' These are small, bean-shaped structures. Their main function is to produce cells that fight disease.
These lymph nodes are spread throughout our bodies, connected to each other by a system of small tubes (the lymphatic system). These tubes filter the fluids (saliva) in our bodies, clean them, and return them to the blood.
The lymph nodes in your groin are also part of this system. There are about 10 lymph nodes located close to the skin (`(superficial)`) on the upper, inner side of your thigh. The lymph fluid that collects from these nodes travels to 3 to 5 lymph nodes that are located a little deeper (`(deep)`). From there, this lymph fluid travels to other lymph nodes in the pelvis and then to other parts of the body.
Why do you want to have surgery to remove these lymph nodes in your groin?
Now you may be wondering, "Why are these little guys being removed?" Well, cancer cells are like nasty, sneaky thieves. These thieves can sneak from one part of the body to another through our lymphatic system, which is what we call the lymph nodes, and spread to other parts of the body.
Our lymphatic system has a pattern of fluid flow. That is, lymph fluid from a certain part of the body first goes to specific lymph nodes. These lymph nodes, where cancer cells are likely to go first, are called sentinel lymph nodes . Think of it like a sentinel.
In particular, cancers that develop in the skin of the penis, vulva, anus, and legs or trunk tend to spread to the lymph nodes in the groin first, and from there, they try to spread to other parts of the body.
Doctors first do a sentinel lymph node biopsy (SLNB). This means they take a lymph node closest to the cancer site, where cancer cells are most likely to go first. If this "sentinel" node is free of cancer cells, it is likely that the other lymph nodes around it are also free of cancer cells.
So, in this way, a lymph node in the groin is taken and examined (biopsy) to see if a nearby cancer has spread to it, or if it has the potential to spread (metastasize) to other parts of the body.
The most important thing is that if this biopsy confirms that there are cancer cells in the lymph nodes in the groin, removing those lymph nodes will greatly help stop the cancer from spreading further throughout the body.
Also, knowing whether or not there are cancer cells in your lymph nodes makes it easier for your doctor to choose the treatment plan that best suits you.
What is this surgery mainly used for?
This groin lymph node dissection (`(Inguinal Lymph Node Dissection)`) is mainly done for the following reasons:
- Find out exactly if the cancer has spread: Especially if the cancer is in the areas we talked about earlier, such as the penis, the external genitalia, the rectum, the legs, or the skin of the trunk.
- Remove lymph nodes that may contain cancer cells or are at high risk of becoming cancerous: Sometimes, even after other treatments, there may still be cancer cells in the lymph nodes. This surgery is also done to remove them.
- Reduce the risk of cancer recurring in the future.
- Help your doctors understand what options are available to treat your cancer and help you know what hope you have for the future.
How is this groin lymph node removal surgery performed?
During this procedure, a surgeon removes lymph nodes and some tissue from your groin area. The removed lymph nodes are then sent to a specialist called a pathologist , who looks at them under a microscope to check for abnormal cells, such as cancer cells.
How should you prepare before surgery?
Your doctor will give you instructions on how to prepare for this surgery. You may need to stop taking certain medications or stop eating and drinking for a few hours before the surgery. They will also tell you how long you will need to stay in the hospital and how to recover after you go home. It is very important that you follow these instructions exactly.
What are the general steps involved in performing the surgery?
These are the steps that typically occur during surgery to remove lymph nodes in the groin:
1. Anesthesia: First, a doctor will inject a drug into a vein in your arm and put you under general anesthesia. This means that you won't feel anything during the surgery, you'll be completely asleep. You won't remember anything about the surgery.
2. Incision: Next, the surgeon makes a small cut (`(incision)`) in the skin of your groin area and removes the lymph nodes that need to be examined. This may be just the lymph nodes that are close to the skin (`(superficial)`), or it may be both the ones that are close to the skin and the ones that are deep (`(deep)`). They will also remove some of the surrounding fatty tissue.
3. Drainage tubes: Small tubes are inserted to drain excess fluid that accumulates at the site of surgery.
4. Stitching the incision: The incision is then closed with stitches.
5. Fluid collection bag: A small bag (`(bag)`) is attached to the end of the tube that drains the fluid to collect it. This can be left in place for a few days to a few weeks.
6. Sending to the laboratory: All removed tissue is sent to the laboratory, to be examined by the pathologist we mentioned earlier.
Some doctors are now performing this surgery using robotic technology, which they say can reduce the risk of complications after surgery.
What can you expect after surgery?
You will stay in the hospital for about two to four days after surgery. Some people may need to stay longer. As soon as you are able to walk safely, your doctors will encourage you to take small walks.
The drainage bag attached to your drainage tube should only be left in place until the amount of fluid draining from it has decreased to the level your doctor expects, or until your doctor decides it is safe to remove it.
How long does it take to heal after having lymph nodes removed from the groin?
It can take several weeks to fully recover from this surgery. You will need to limit physical activities, such as driving, for about four to six weeks. Your doctor will tell you exactly what you can and cannot do. Following those instructions is very important for a speedy recovery.
What are the possible risks and side effects of this surgery?
As with any surgery, there are some risks. The most common complications and side effects after inguinal lymph node removal are:
- Infection of the surgical incision: The incision site may become red, swollen, and painful.
- Fluid accumulation and swelling at the incision site.
- Swelling in the lower legs (lymphedema): This can occur due to obstruction of the flow of lymph fluid due to the removal of lymph nodes.
- Blood clots (DVT - Deep Vein Thrombosis): Blood clots can form, especially in the deep veins of the legs.
- Delayed wound healing.
- Numbness in the upper thigh: This is often a long-term side effect because some nerves may be removed during the surgery.
If you suspect any of these, it is important to inform your doctor immediately.
What are the results after surgery? What do those results mean?
As we mentioned earlier, the pathologist is the one who checks the removed lymph nodes for cancer cells.
- Lymph nodes that contain cancer cells are considered "positive."
- Lymph nodes that do not contain cancer cells are considered "negative."
The pathologist will also note in his report (`(report)`) how many lymph nodes were found to contain cancer cells, out of the total number of lymph nodes removed.
Also, he can note a few other things:
- Type of cancer: What type of cancer is it?
- The grade of cancer (`(grade)`): This refers to how similar or different the cancer cells are from normal healthy cells.
- Mitotic rate: How fast cancer cells divide.
- Margins: If a piece of tissue is removed without lymph nodes, the edges of the tissue are checked for cancer cells. A "positive margin" means that there are cancer cells at the edges. A "negative or clear margin" means that there are no cancer cells at the edges.
All of this information is very important for the doctor to plan your future treatment.
How long does it take to see the results of the surgery?
It can take anywhere from a few days to a week or more to get your biopsy results. Ask your doctor how long it will take to get your results.
If the results are abnormal, what do you do next?
If your results show any abnormalities, such as cancer cells, your doctor will tell you what to do next. You may need additional treatment or surgery. Don't panic, talk to your doctor and make your decisions.
When should I call my doctor?
Call your doctor right away if your surgical incision is not healing or if you have signs of infection. Such signs include:
- Fever (`(Fever)`)
- Severe pain (`(Pain)`)
- Redness, pus or discharge at the incision site
If you see things like this, it is very important to seek medical advice without delay.
Finally, things you need to remember (Take-Home Message)
So, an inguinal lymph node dissection is an important surgery to see if cancer has spread. It gives you and your doctor a lot of important information about your health. You can use that information to make decisions about your future treatment together.
Give yourself plenty of time to recover after this surgery. Get plenty of rest. Don't rush things. Follow the doctors' instructions exactly.
If you have any questions or concerns about the surgery, the results, or the recovery time, don't be afraid to ask your doctor for clarification. It's very important to talk to them about what's on your mind. We wish you a speedy recovery!
