A hernia occurs when tissue bulges out through an opening in the muscles. Any part of the abdominal wall can weaken and develop a hernia, but the most common sites are the groin (inguinal), the navel (umbilical) and a previous surgical incision site. An inguinal hernia in the groin is more common in men. A femoral hernia may be at the upper leg, vaginal area or groin, and is more common in women.
Open Hernia Repair
An incision is made near the site and the hernia is repaired with mesh or by suturing (sewing) the muscle closed.
Laparoscopic Hernia Repair
The hernia is repaired by mesh or sutures inserted through instruments placed into small incisions in the abdomen.
Nonsurgical Procedure
About 1/3 of groin hernia patients have no symptoms. Watchful waiting may be a safe option for adults who are not uncomfortable. Most men with an inguinal hernia need surgery due to increased pain with exercise, chronic constipation or urinary symptoms. 23% crossed over to surgery after 2 years and 50% after 5 years.2
An operation is the only way to repair a hernia. You can return to your normal activities and in most cases will not have further discomfort. Possible risks include—Return of the hernia; infection; injury to the bladder, blood vessels, intestines or nerves, difficulty passing urine, continued pain, and swelling of the testes or groin area.
Your hernia may cause pain and increase in size. If your intestine becomes trapped in the hernia pouch you will have sudden pain, vomiting, and need an immediate operation.
Before your operation—A physical examination is usually all that is needed to diagnose groin hernias.2 Evaluation may include blood work and urinalysis. Your surgeon and anesthesia provider will discuss your health history, home medications, and pain control options.
The day of your operation—You will not eat or drink for 4 hours before the operation. Most often you will take your normal medication with a sip of water. You will need someone to drive you home.
Your recovery—If you do not have complications you usually will go home the same day. You may return
to work after 1 to 2 weeks after laparoscopic or open repair, as long as you don’t do any heavy lifting.
Call your surgeon if you have:
There may be no cause for a hernia. The risk of developing an inguinal hernia is 3% for women and 27% for men.3 Inguinal hernias are 8-10 times more common in men.2 Some risk factors are:
Other medical disorders that have symptoms similar to hernias include enlarged lymph nodes, cysts, and testicular problems such as scrotal hydrocele.
A groin hernia occurs when the intestine bulges through the opening in the muscle in the groin area. A reducible hernia can be pushed back into the opening. When intestine or abdominal tissue fills the hernia sac and cannot be pushed back, it is called irreducible or incarcerated. A hernia is strangulated if the intestine is trapped in the hernia pouch and the blood supply to the intestine is decreased. This is a surgical emergency.6
There are two types of groin hernias:
An inguinal hernia (IH) appears as a bulge in the groin or scrotum. Inguinal hernias account for 75% of all hernias and are most common in men.2 A femoral hernia (FH) appears as a bulge in the groin, upper thigh, or labia (skin folds surrounding the vaginal opening). Femoral hernias are four times more common in women.7 They are always repaired because of a high risk of strangulation.2 Herniorraphy is the surgical repair of a hernia. Hernioplasty is the surgical repair of a hernia with mesh.
The type of operation depends on hernia size and location, and if it is a repeat hernia. Your health, age, anesthesia risk, and the surgeon’s expertise are also important. An operation is the only treatment for incarcerated/strangulated and femoral hernias.
Your hernia can be repaired either as an open or laparoscopic approach. The repair can be done by using sutures only or adding a piece of mesh.
Open Hernia Repair
The surgeon makes an incision near the hernia site and the bulging tissue is pushed back into the abdomen. Most inguinal hernia repairs use mesh to close the muscle and to decrease recurrence.2 An open repair can be done with local anesthesia.
For an open mesh repair: The hernia sac is removed. Mesh is placed over the hernia site. The placement of of mesh is the most agreed upon approach in IH repair.2 Mesh is often used for large hernia repairs and may reduce the risk that the hernia will come back. The site is closed using sutures, staples, or surgical glue.
For a suture-only repair: The hernia sac is removed. Then the tissue along the muscle edge is sewn together. This procedure is often used for strangulated or infected hernias or small defects (less than 3 cm).
Laparoscopic Hernia Repair
The surgeon will make several small punctures or incisions in the abdomen. Ports (hollow tubes) are inserted into the openings. The abdomen is inflated with carbon dioxide gas to make it easier to see the internal organs. Surgical tools and a laparoscopic light are placed into the ports. The hernia is repaired with mesh and sutured or stapled in place. The repair is done as a TransAbdominal PrePeritoneal (TAPP) procedure, which means the peritoneum (the sac that contains all of the abdominal organs) is entered, or the repair is done as a Totally ExtraPeritoneal (TEP) procedure.8
Watchful waiting is an option if you have an inguinal hernia with no symptoms.2 Hernia incarceration occurred in less than 1% of men who waited longer than 2 years to have a repair.9 Femoral hernias should always be repaired due to an increased risk of incarceration or strangulation and the risk is increased if the hernia is right-sided.10 Trusses or belts attempt to manage symptoms by applying pressure at the site however they are not recommended as they may cause complications like testicular nerve damage and incarceration.9
The site is checked for a bulge. Other tests may include (see glossary):
A laparoscopic repair of inguinal hernia may result in less pain and numbness, lower infection rate, and faster return to normal activity than open repair. When surgeons have experience with laparascopic repair, operation times, and complication rates compare to open suture repair. In follow-up after 48 months there was no difference in severe chronic pain and long-term recurrence between the types of repair.11
Repairing both sides of the hernia at the same time (bilateral repair) when done by an experienced laparoscopic surgeon has faster recovery, lower reports of chronic pain and is cost effective.12
Risks |
Percent for Average Patient |
Keeping You Informed |
Wound Infection: Infection at the area of the incision or near the organ where the surgery was performed |
Open 0.4% Laparoscopic 0.3% |
Antibiotics and drainage of the wound may be needed. Smoking can increase the risk of infection. |
Complications: Including surgical infections, breathing difficulties, blood clots, renal (kidney) complications, cardiac complications, and return to the operating room |
Open 1.6% Laparoscopic 1.5% |
Complications related to general anesthesia and surgery may be higher in smokers, elderly and/or obese patients, and those with high blood pressure and breathing problems. Wound healing may also be decreased in smokers and those with diabetes and immune system disorders. |
Pneumonia: Infection in the lungs |
Open 0.1% Laparoscopic 0.1% |
Movement, deep breathing, and stopping smoking can help prevent respiratory infections. |
Urinary tract infection: Infection of the bladder or kidneys |
Open 0.2% Laparoscopic 0.2% |
Drinking fluids and catheter care decrease the risk of bladder infection. |
Venous thrombosis: A blood clot in the legs that can travel to the lungs |
Open 0.1% Laparoscopic 0.1% |
Longer surgery and bed rest increase the risk. Getting up, walking 5 to 6 times per day, and wearing support stockings reduce the risk. |
Death |
Less than 1% |
Your surgical team is prepared for all emergency situations. |
Risks from Outcomes Reported in the Last 10 years of Literature |
Percent for Average Patient |
Keeping You Informed |
Chronic (long-term) pain |
10% to 12% may have pain one year after surgery; possibly less with lapraoscopic 13 |
Factors contributing to chronic pain include emergency hernia repair, scrotal hernia, recurrent hernia repair, young age, female gender, perioperative pain, open hernia repair, perioperative complications, and penetrating mesh fixation.1 Pain caused by compression or tension may gradually decrease with time as a result of tissue rearrangement.14 |
Recurrence: A hernia can recur after the repair |
All patients 1% to 17% 15 Open 4.9% Laparoscopic 10.1% |
Recurrence occurs less often when mesh is used versus non-mesh repair.16 Laparoscopic repair is recommended for recurrent hernias because the surgeon avoids previous scar tissue. There is a higher rate of recurrence in older men with laparoscopic repair. |
Neuralgia: Nerve pain causing tingling or numbness |
Open 10.7% Laparoscopic 7.4% |
Pressure, staples, stitches, or a trapped nerve in the surgical area can cause nerve pain. Tell your doctor if you feel severe, sharp, or tingling pain in the groin and leg immediately after your procedure; an operation may be required if the nerve is trapped.16 |
Seroma: A collection of clear/yellow fluid |
5-25% 17 |
Seromas can form around the former hernia site. Removal of fluid with a sterile needle may be required. |
Hematoma: a collection of blood in the wound site or scrotum |
3.4% 18 |
Hematomas are treated with anti-inflammatory medications, elevation, and rest. Rarely blood replacement or further testing for a blood vessel injury is needed. |
The ACS Surgical Risk Calculator estimates the risk of an unfavorable outcome. Data is from a large number of patients who had a surgical procedure similar to this one. If you are healthy with no health problems, your risks may be below average. If you smoke, are obese, or have other health conditions, then your risk may be higher.

Advance directives: Documents signed by a competent person giving direction to health care providers about treatment choices.
Computerized tomography (CT) scan: A diagnostic test X ray and a computer to create a detailed, three-dimensional picture of your abdomen. A CT scan is commonly used to detect abnormalities or disease inside the abdomen. It is sometimes used to find a hernia not obvious during the physical exam.
Digital exam: The examiner will place their gloved index finger gently into the scrotal sac and feel up to the inguinal ring in the groin. Then the patient is asked to strain.
Electrocardiogram (ECG): Measures the rate and regularity of heartbeats and any damage to the heart.
General anesthesia: A treatment with certain medicines that puts you into a deep sleep so you do not feel pain during surgery.
Hematoma: A collection of blood that has leaked into the tissues of the skin or in an organ, resulting from cutting in surgery or the blood’s inability to form a clot.
Incarceration: The protrusion or constriction of an organ through the wall of the cavity that normally contains it.
Local anesthesia: The loss of sensation only in the area of the body where an anesthetic drug is applied or injected.
Nasogastric tube: A soft plastic tube inserted in the nose and down to the stomach which is used to empty the stomach of contents and gases to rest the bowel.
Seroma: A collection of serous (clear/yellow) fluid.
Strangulation: Part of the intestine or fat is squeezed in the hernia sac and blood supply to the tissue is cut off.
Ultrasound: Sound waves are used to determine the location of deep structures in the body. A hand roller is placed on top of clear gel and rolled across the abdomen. An ultrasound may be used to find a hernia that is not obvious during the physical exam.
Urinalysis: A visual and chemical examination of the urine, most often used to screen for urinary tract infections and kidney disease.
