Have you ever noticed a small bulge coming out of some part of your stomach? Maybe you see it when you lift something heavy, when you cough, or maybe it just goes back in after a while. This is what we simply call a hernia. Today we are going to talk about a type of hernia that occurs in the front of the stomach, which is medically known as a ventral hernia . There is nothing to be afraid of, we will talk about this in detail, in a way that you can understand.
What is a ventral hernia?
Simply put, a ventral hernia is a protrusion of an internal organ or tissue through the front of your abdomen, that is, through the muscles of the abdominal wall. The word "ventral" means "front" or "belly side." A "hernia" is when an organ or tissue that is normally inside a body cavity pushes through a weak spot, a hole, in the wall of that cavity. It's like a small hole in an old bag, and some of the stuff inside is trying to come out. Most hernias (not all) come through the abdominal wall.
What are the types of ventral hernia?
Ventral hernias can occur in various places on the front wall of your abdomen. There are several main types depending on where they occur:
- Epigastric hernias: These occur in the upper part of your stomach, between your breastbone (sternum) and your navel. Some people may feel like a small bulge in this area.
- Umbilical hernias: These are hernias that occur around the navel. The navel is a naturally weak spot. This type of hernia is sometimes present at birth (congenital). However, it can also occur in adults.
- Incisional hernias: These are a bit special. They occur where you have had previous surgery on your abdomen, meaning where there was a surgical incision. This is a common side effect that can occur after abdominal surgery. This is because the muscles in that area are weakened after surgery.
What are the symptoms of a ventral hernia?
Often the first sign of a ventral hernia is a visible bulge somewhere in the front of the abdomen . This may not always be visible. It may appear when you do certain things or when your abdominal muscles tighten due to a position. For example:
- When laughing
- When crying
- When coughing
- When you sneeze
- Straining to defecate while going to the toilet
- When bending forward
- When lifting a weight
- When exercising
Some people can feel the hernia. It may feel like it is pulling, pushing, or pinching when it comes out, or when they move. It may just feel like a pulling, or it may feel like a dull ache, or it may feel like a sharp stabbing pain . This pain means that the hernia is a bit large, and it is more likely to become ``incarcerated`` when it comes out.
A more complex hernia may have other symptoms:
- Nausea and vomiting
- Redness or a rash like eczema at the hernia site
What are the main causes of Ventral Hernia?
A hernia protrudes through a weakness in the muscle or tissue wall that covers it. This weakness can occur for a number of reasons:
- This weakness may be a congenital weak spot / birth defect. That is, there may be a weakness in the abdominal wall at birth.
- Some connective tissue diseases can also cause muscle weakness.
- One reason is that muscles naturally weaken with age .
- Chronic obesity causes continuous pressure on the abdominal wall.
- Muscle weakness can occur due to an injury or surgery to the abdomen .
- Pregnancy and childbirth are times when the abdominal muscles are under great strain.
- Persistent cough (e.g. due to conditions such as asthma and bronchitis in some people).
- Chronic breathing problems (e.g., COPD or emphysema).
- Chronic constipation or frequent straining to defecate.
- This risk is also higher for those who work in jobs that involve frequent lifting or pushing . For example, someone working in the construction industry has to lift heavy objects all the time. This puts constant pressure on the abdominal muscles. Over time, a hernia can develop from a weak spot.
Often, a hernia develops due to a combination of more than one of these causes.
What are the possible complications of a ventral hernia?
Many hernias initially come out and then go back in. But as they go in and out like this, the tissue around the hole becomes weaker. Over time , the hole can get bigger, and the hernia can get bigger too . That means more organs come out. That's when complications start to occur.
The hernia is more likely to become large and become ``incarcerated'' within that hole.
When it gets stuck, the hernia pushes, pain occurs, and the organ in question can become blocked. Imagine a blocked intestine, which means that the passage of stool can stop. What's even more dangerous is that if the blood supply to that stuck part is cut off (strangulation) , that organ can die (tissue death). This is a very serious situation and can be life-threatening.
How to diagnose a ventral hernia?
A doctor will usually find a ventral hernia during a physical exam. If it's not immediately obvious, your doctor will ask you to hold yourself in different positions or do certain things (like coughing or squeezing your stomach) to see if the hernia comes out.
Sometimes imaging tests may be done to see the hernia clearly. This may include an abdominal ultrasound, a CT scan, or an MRI.
If the doctor sees a hernia, he or she will feel it and see if the hernia can be pushed back in. This will help determine how serious it is and how quickly treatment is needed. The doctor will also ask you about your symptoms, your medical history, and any other factors that may have caused the hernia:
- When did you first see this?
- Has this changed over time? (Did it get bigger, did the pain increase?)
- What kind of difficulties are you having because of this?
- What other chronic diseases do you have?
- What is your job?
- How is your diet, exercise, and lifestyle?
Does a ventral hernia need to be repaired?
Most ventral hernias will need to be repaired at some point , but not all of them need to be repaired immediately. If you don't have any major symptoms and can push the hernia back in, there's probably no immediate risk.
But remember, hernias are more likely to get worse and larger over time . When that happens, they can become more dangerous and more difficult to repair.
Most importantly: A hernia that cannot be pushed back in (an incarcerated hernia) is an emergency and should be reported immediately to a hospital emergency department (ETU) .
When does a ventral hernia require surgery?
Surgeons recommend ventral hernia repair in the following cases:
- If the hernia cannot be put back in (irreducible).
- If you have symptoms like constant pain because of that.
- If it is large enough to become stuck or cause other complications .
- If your general health condition allows you to undergo surgery .
If a young child has an umbilical hernia and it doesn't heal on its own within a few years, the doctor will recommend surgical repair to prevent it from getting bigger and causing problems.
How to repair a ventral hernia?
The main goal of ventral hernia surgery is to close the hole in your abdominal wall and prevent the hernia from coming back out . The surgery restores the shape and strength of the abdominal wall, closes the hole, and puts the muscles back in place. Often, surgeons use surgical mesh to strengthen the wall.
Is Ventral Hernia Surgery a Major Surgery?
Ventral hernia surgery is a very common, usually simple, procedure . In the United States alone, about 350,000 such surgeries are performed each year. In most cases, surgeons can use minimally invasive methods . This means that it can be done through small incisions, which means less recovery time. However, some people, especially if the hernia is very large or complex, may need to have major surgery called open abdominal surgery .
Your surgeon will determine the surgical procedure that is best suited for your hernia. There are several main methods:
- Open ventral hernia repair: This is the traditional method. The surgeon cuts the skin over the hernia, opens the area, and repairs the hernia directly. This method may be necessary if the hernia is more complex.
- Laparoscopic ventral hernia repair: This is a minimally invasive procedure. The surgeon makes several small "keyhole" incisions in your abdomen, about half an inch long. A small camera called a laparoscope is inserted through one incision. The images are shown on a screen. Long, thin instruments are inserted through other incisions and the surgery is performed while looking at the screen.
- Robotic ventral hernia repair: This is another minimally invasive procedure. It also uses small incisions, long instruments, and a laparoscope. The difference is that the surgeon controls the instruments through a computer system using a robotic arm.
Does every ventral hernia require mesh?
No, not all ventral hernias require mesh . Especially if they are small epigastric or umbilical hernias. However, many incisional hernias require mesh . This is because they are formed through tissue that has been cut from a previous surgery. After surgery, the muscle tissue is never as strong as it was before. The hernia repair surgery also weakens it again. Therefore, mesh provides additional strength.
Surgeons have different types of surgical mesh to choose from:
- Synthetic mesh: These are made from man-made, permanent materials. These are the most durable type of mesh used to make implants. As new tissue grows around the mesh, the mesh becomes embedded within the tissue, creating a strong, permanent layer that does not break down over time like tissue.
- Biological mesh: These are made from human or animal tissue (e.g., animal skin). They don't last as long as synthetic mesh, but they have a lower risk of infection. Although the overall risk of infection is low, some people are more at risk of infection than others. So a biological mesh may be safer for those people.
- Bioabsorbable synthetic mesh: This is a temporary mesh. It provides short-term support while the surgery heals. After it is absorbed by the body, scar tissue forms and strengthens the wall.
Are there any non-surgical options for ventral hernia?
In fact, surgery is the only way to completely repair a ventral hernia. However, some people may not be able to have surgery due to other health conditions. If you have a large hernia that cannot be repaired with surgery, your doctor may suggest using a special support (such as a corset, binder, or truss) to hold the hernia in place. This will not heal the hernia, but it can help reduce discomfort and prevent it from becoming trapped.
How serious is a ventral hernia?
Most ventral hernias are not serious at first, but they can become more serious over time. That's why doctors recommend getting them repaired before they get to that point.
The results of elective surgery, performed before complications arise, are always better than emergency surgery, performed after complications arise.
What happens after ventral hernia surgery?
Most hernia surgeries are simple, and the recovery time is quick. More complex hernias may require a larger operation and may take longer to heal. The most important thing is to be careful not to put pressure or strain on the hernia during the healing process. It is important to follow your doctor's instructions to prevent a hernia from recurring. Between 10% and 20% of ventral hernias can recur after surgery.
There are many reasons why you might develop a ventral hernia. Most often, it develops gradually, over years. If you know that something you do every day (e.g., lifting weights, frequent squatting) is putting pressure on your abdominal muscles, you may be able to change that habit or get treatment for a chronic condition that could help control the development of this condition.
But not all hernias can be prevented. If you get one, remember that you are not alone. They are very common, and so is the surgery to repair them. Your doctor will advise you when to have your hernia repaired. You may not need it right away, but it is best to have it repaired before it gets too big.
Important things to know (Take-Home Message)
Well, I hope that from what we have discussed, you have gained a good understanding of Ventral Hernia. Here are some things to keep in mind:
- A ventral hernia is a protrusion of internal organs through a weak spot in the front wall of the abdomen. This can occur in the navel, below the chest, in the upper abdomen, or at a site of previous surgery.
- Symptoms may include abdominal swelling, especially when coughing or lifting heavy objects. There may also be pain.
- Even if a problem doesn't seem like a big deal at first, it can grow bigger, become more complicated, and become dangerous over time. So it's not a good idea to ignore it.
- If you have these symptoms and feel like your hernia is getting bigger, it's best to see a doctor for advice.
- In most cases, this can be completely cured with surgery. So don't be afraid, get treatment at the right time.
If you have any further questions about this, be sure to talk to your family doctor or a surgeon. Stay healthy!
