You too may have been told by a doctor that a "mesh" needs to be inserted for a hernia or to strengthen a weak spot in your abdomen. It's normal to feel a little nervous when you hear that. But when you know exactly what this "mesh" or, as doctors call it, surgical mesh is and what it does, your fears and doubts will be greatly reduced. So, today, let's talk about this surgical mesh in simple terms.
What is this surgical mesh?
Simply put, surgical mesh is a mesh that is used to strengthen weakened or damaged body tissue. It is similar to using a new piece of fabric to reinforce an old piece of fabric. It is often used to repair weak areas in your abdomen (belly) or groin area.
This mesh is often made from man-made synthetic materials, but sometimes it is made from animal tissue. A surgeon makes an incision in your body and inserts the mesh. Then, as your body heals, new tissue grows around the mesh. Think of it like a tree growing along a wire fence, or like cement filling around the rebar when pouring concrete. This is how the mesh strengthens the area.
Some people also call this "abdominal mesh", and because it is used for hernias, it is also called "hernia mesh".
What is surgical mesh used for?
Doctors often recommend a surgical mesh if you have a hernia . A hernia is simply a protrusion of an organ or tissue inside your body through a weak spot in the muscles or other tissue. Think of it like a tube popping out of a weak spot in a tire.
Surgeons can close these weakened areas with stitches. However, sometimes, over time, with the stress of daily activities, the stitches can become loose again. That's when surgical mesh comes to the rescue. It provides extra strength to the closed area, helping to keep the weakened muscle from becoming loose again.
What is this surgical mesh made of?
Surgical mesh is made from a variety of materials. These can be synthetic polymers or biopolymers . Synthetic polymers are things that people make in factories, often from petroleum. Biopolymers are things that come from living cells.
Materials used may include:
- Absorbable synthetic polymers - for example , polyglycolic acid or polycaprolactone .
- Biologic - acellular collagen obtained from cows or pigs.
- Composite - A combination of any three of these materials.
- Non-absorbable synthetic polymers - an example is polypropylene . This is the most commonly used.
This mesh comes in different shapes. Some are knitted , some are woven .
Knitted surgical mesh is made from a single length of thread that is looped together. It looks like a knitted sweater. This type of mesh is flexible and porous, allowing tissue to grow into the mesh.
Woven surgical mesh has threads woven over, under, and across each other in a checkerboard pattern. It works like the wire mesh used to reinforce concrete in roads and buildings. The mechanical properties of a woven mesh are the same everywhere . This means that every square in the mesh can withstand the same amount of tension and pressure.
How long does a surgical mesh last?
This varies depending on the type of mesh used.
If you put a non-absorbable mesh on your body , it will permanently strengthen and attach to your muscle or tissue.
Absorbable mesh is not permanent. Over time, your body will slowly absorb it and grow new tissue or muscle in its place.
Each type of mesh has its advantages and disadvantages. Your surgeon will choose the type that is right for you and explain the pros and cons of each to you. You can ask any questions you have at that time.
How does a surgeon insert a surgical mesh?
This will vary depending on the type of hernia surgery you are having. But in general, a surgeon will:
1. If you are having open surgery , a single incision will be made, a few inches long. Otherwise, if you are having laparoscopic surgery or robotic surgery , several smaller incisions will be made.
2. Next, the herniated tissue is put back in place and the weakened area of the muscle is closed with sutures .
3. Then, to further strengthen the created area , surgical mesh is placed under, between, or above the muscle and fixed.
4. Finally, the incisions are closed again with stitches.
Where is the surgical mesh placed?
This depends on the location and severity of your hernia. A surgeon may place the mesh in the following places:
- Between your intestines and the abdominal wall.
- Between the muscle layers of your abdominal wall.
- On the outside of your abdominal wall.
Your doctor will explain this to you during the pre-surgery consultation.
What are the benefits and risks of surgical mesh?
The main advantage is that surgical mesh is generally a safe, effective, and widely used hernia treatment. Also, the risk of a hernia coming back after a mesh is placed is much lower.
However, like any medical procedure, there are some risks involved. Here are the risks associated with surgical mesh :
- Infection .
- Non-absorbable synthetic surgical mesh can sometimes rupture and cause the muscle to re-invade (hernia recurrence) .
- Very rarely, mesh placed close to organs can erode other organs, such as the intestines or urinary bladder.
- The mesh is not properly attached to your muscle tissue.
These risks are very low . However, before having any surgery, you and your doctor should discuss the pros and cons of having surgery and not using mesh. In most cases, a surgeon will decide to repair a hernia and insert mesh if the risks to you are greater than the risks of not repairing the hernia and not using mesh. For example, if you have a hernia, it can lead to serious conditions such as bowel obstruction or bowel strangulation , which may require emergency surgery. However, many people have a hernia repaired because of the pain and impact on their quality of life.
Some common risks of surgery are:
- Anesthesia problems .
- Excessive bleeding .
- Chronic numbness or pain in the surgical area, possibly due to nerve damage.
How long will it take for me to recover?
This will also vary depending on the type of hernia, its severity, and the type of surgery you had. But usually, you can go back to work or school in about a week. However, if you have a physically demanding job or if your hernia is large, you may need to rest for a little longer. Your surgeon will discuss this with you.
Starting the day after surgery, you can do light exercises, such as walking, as much as you can. You should wait at least two weeks before doing things like running, cycling, or swimming. You may need to wait several months before doing high-impact exercises, such as sprinting, playing sports, or lifting weights.
What can I do to make the recovery time with surgical mesh easier?
After having a surgical mesh, you can do the following to make your recovery easier:
- Avoid straining when going to the toilet.
- Drink plenty of fluids, including water.
- Take pain medications as prescribed by your doctor.
- Take a short walk every day. It will improve your blood circulation and make it easier to defecate and urinate.
When should I see a doctor?
After having a surgical mesh inserted, see a doctor immediately if you have any of these symptoms:
- Severe pain .
- Signs of infection : discoloration of the incision site (red, purple, brown, or black), fever, or yellow pus-like fluid draining from the incision.
- Symptoms of Irritable Bowel Syndrome : Constipation, diarrhea, gas and bloating.
Finally, the most important thing
It's normal to feel a little nervous and scared when you're going to have hernia surgery. However, remember that surgical mesh is a widely used, effective medical device that reduces the chance of a hernia coming back. Your surgeon will explain the best options to you and recommend the best one based on your condition and preferences. They will also tell you what to expect during your recovery and what to do if any complications arise. If you have any questions or concerns, don't hesitate to ask your doctor.
