Hernia surgical mesh has quickly become the medical standard for repairing hernias. Studies have shown it to be more reliable at preventing recurrences, but, as with any surgery, hernia repairs pose the risk of complications.
Hernias occur when the intestines or other internal organs break through weakened or damaged muscle tissue which normally holds them in place.
Hernias are one of the most common anatomical conditions people may suffer. The overall chance of a person developing a hernia at some point in their lifetime is about 10 percent. The likelihood is higher for men — 27 percent — than for women — 3 percent.
Surgery is the only way to permanently correct a hernia. More than 5 million hernia surgeries are performed every year in the U.S.
Two types of hernias — inguinal (inner groin) and umbilical (around the navel) — account for most hernia surgeries in the U.S. About 75 percent of hernias are inguinal — occurring between the abdomen and the thigh. Umbilical hernias are most common in infants and usually heal themselves by the time the child is 4 years old. Only about 10 percent of abdominal hernias in adults are umbilical hernias.
Other types of hernias include femoral (outer groin), hiatal (upper stomach) and incisional (resulting from an incision).
According to the U.S. Food and Drug Administration (FDA), the use of surgical mesh may improve a patient’s outcome by decreasing the time the surgery takes and minimizing the recovery time. However, recovery time can vary depending on the type of hernia, the patient’s condition both before and after surgery, and the surgical approach.
Hernias can be extremely painful and limit mobility or physical activity. Pressure on the damaged tissue can cause the hernia to worsen, expanding the tear. Surgery is usually recommended as soon as possible to prevent the condition from worsening.

Doctors may perform hernia repair surgery with or without surgical mesh. Hernia repair surgery with mesh is called hernioplasty and without mesh it is called herniorrhaphy.
Done without mesh, the torn tissue is sutured back together, but this has a much higher likelihood of rupturing again in the future.
Surgical mesh acts as flexible scaffolding to repair muscle walls and prevent organs from coming through. After placing the mesh over the hernia defect, doctors use sutures, tacks or surgical glue to hold the mesh in place. Over time, the patient’s tissue should grow into the small pores in the mesh and strengthen the muscle wall. Most mesh repairs are permanent, meaning the implant remains in the body for the rest of the patient’s life.
Advances in materials and surgical techniques have allowed rapid growth of hernia mesh in repair surgeries.

There are two types of surgery to repair hernias: laparoscopic repair and open repair.
This is a minimally invasive form of surgery. The surgeon makes several small incisions and inserts surgical tools through the openings to repair the hernia. This procedure typically involves a shorter healing time and less blood loss, but it is more challenging to perform and costs more. Surgeons use laparoscopic repair to fix a hernia recurrence because it avoids old scar tissue. Recovery time is one to two weeks, and strenuous exercise is generally allowed after about four weeks.
The surgeon makes an incision near the hernia to repair the weak muscle area. This procedure can be done with or without surgical mesh. Recovery time is about three weeks, and strenuous exercise is generally allowed after six weeks. Open repair that uses sutures without mesh is referred to as primary closure and is used to repair inguinal (of the groin) hernias in infants, small hernias, or strangulated or infected hernias.
Surgeons may use three main techniques to repair hernias with mesh: transabdominal preperitoneal (TAPP) repair, totally extraperitoneal (TEP) repair and intraperitoneal onlay mesh technique (IPOM). Most surgeons use the TAPP or TEP techniques.
The FDA cautions that the use of surgical mesh for hernia repair may not be the best treatment option for every patient.
“Despite reduced rates of recurrence; there are situations where the use of surgical mesh for hernia repair may not be recommended. Patients should talk to their surgeons about their specific circumstances and their best options and alternatives for hernia repair,” according to the agency.
The FDA recommends patients requiring hernia surgery discuss the pros and cons of surgical mesh with their doctors.
The FDA also recommends patients request a copy of any patient information included with the hernia mesh used in the procedure.
There have been only a few, early studies that have compared the outcomes of open mesh, laparoscopic mesh and non-mesh hernia repair surgeries. A 2016 Danish study of 3,400 patients published in JAMA (Journal of the American Medical Association) found mixed results. Researchers found that while the rate of long-term complications was higher for surgeries using mesh, mesh prevailed at preventing recurrences of hernias — one of the most common problems hernia patients faced prior to the introduction of surgical mesh.
A comparison of the pros and cons of hernia surgery using surgical mesh to non-mesh hernia repair shows benefits and shortcomings for both options.
|Condition||Hernia Mesh Repair||Non-Mesh Repair|
|Surgery time||1 – 2 hours||45 minutes|
|Hospital stay||Less than one day||Less than one day|
|Early complications||About the same rate for both||About the same rate for both|
|Later complications (including organ damage and infections)||3% - 6%||1% or less|
|Revision surgery rate||10% - 12%||17%|
|Hernia recurrence rate||Less than 3%||1% to 8%|
|Time to resume light activities||1 – 2 Weeks||5 – 6 Weeks|
|Time to resume full activities||4 – 6 Weeks||15 – 16 Weeks|
There are also differences between open hernia repair surgery and laparoscopic surgeries. Researchers in the Danish study found recurrence rates and complication rates were lower for laparoscopic hernia repairs.
Hernia surgery is usually an outpatient procedure, meaning it does not require an overnight stay in the hospital. The typical surgery lasts about two hours and is performed by either a general surgeon or an urologist.
Patients undergoing hernia surgery should arrange for someone to take them to and from the hospital on the day of the surgery, and to stay with them for at least a few days after the surgery.
Laparoscopic hernia repair, a minimally invasive form of hernia surgery, is always done under general anesthesia while more open hernia repairs may be done under general, spinal or local anesthesia accompanied by sedation.
Patients may be told to stop aspirin or blood thinners a week before surgery since these can slow clotting and cause excess bleeding during surgery and may slow the healing process.
A 2017 survey of insurance claims databases estimates the cost of all types of hernia surgery is between $5,800 and $7,800. The survey estimated that only about $850 of that is for the doctor’s charge for the procedure itself, while the rest is for other hospital charges, such as operating and recovery rooms and anesthesia.
The incidence of a person acquiring a hernia rises from 10 percent to 50 percent by the time a person is 75. Most of these patients will be covered in part by Medicare.
Medicare Part B covers 80 percent of outpatient procedures including hernia surgeries. Based on the estimates above, a Medicare deductible patient would be responsible for about $1,160 to $1,560 of the cost of an inguinal hernia type surgery.
The average cost of umbilical hernia surgery ranges from $4,000 to $11,000. Medicare patients would have out-of-pocket expenses ranging from $800 to $2,200.
It can take several days to recover from laparoscopic surgery and even longer from open hernia surgery. The doctor will prescribe pain medication, and it is important the patient not exceed the recommended dosage.

Patients should take frequent, short walks to improve circulation and prevent dangerous blood clots from forming in the legs. An ice pack placed on the incision for no more than 20 minutes three to five times a day can help decrease swelling.
A healthy diet and plenty of water are necessary to promote proper recovery.
It may be a week or more before the patient should lift heavy objects. The doctor will advise when it is safe to lift or carry things.
Patients should also seek their doctor’s advice on when it is safe for them to return to work. The doctor will likely recommend the patient not shower for at least a day after the procedure.
The doctor will likely schedule follow-up appointments one or two weeks after the surgery to make sure the patient’s recovery is progressing without complications.
Patients experiencing certain symptoms following hernia repair surgery should contact their doctor immediately.
People who smoke and/or who are obese may require extra considerations. A University of Michigan report notes that smoking may lead to an infection of the mesh. This may require treatment by intravenous antibiotics, drainage and additional surgery to remove the mesh. The report also cautions against undergoing weight-loss surgery and hernia repair at the same time as it greatly increases the risks for infection of the mesh.
Some of the most serious complications following hernia repair surgery with mesh can require a revision surgery to remove, replace and again repair the hernia.
In the worst of these situations, a surgeon may have to remove portions of healthy tissue to repair damage or remove part of the intestines if it adheres to the mesh.
Revision surgery has a similar recovery time as the initial surgery and may involve the same techniques. It can be more complex due to scar tissue from the first surgery and the particular complication requiring a revision in the first place.
