Inguinal Hernia Repair

Introduction

If you have been told you have an inguinal hernia, or you have noticed a bulge in your groin that comes and goes when you stand, cough, or lift something heavy, you are likely now thinking about repair. Inguinal hernia repair is one of the most common operations performed in general surgery worldwide. The techniques are well established, the recovery is usually short, and most people return to their normal lives within a few weeks.

This guide is written for someone who is already planning surgery or weighing up whether and when to have it. It explains what an inguinal hernia is, why repair is offered, the different surgical approaches available, what happens before and during surgery, what recovery looks like, and what life is like after the operation. It also covers inguinal hernia repair in children, where the surgery is different in important ways.

The decisions about whether to repair, when to repair, and which approach to use are clinical ones that you will make together with your surgeon. The aim here is to help you walk into that conversation with a clear understanding of the landscape.

What Is an Inguinal Hernia?

An inguinal hernia is a bulge in the lower abdomen or groin that happens when tissue from inside the abdomen — most often a loop of intestine or a piece of the fatty lining called the omentum — pushes through a weak area in the abdominal wall. The weak area is in or near a natural passage called the inguinal canal.

The inguinal canal exists in everyone. In men, it carries the spermatic cord, which connects the testicle to structures inside the abdomen. In women, it carries a ligament that supports the uterus. Because this canal is a natural opening in the abdominal wall, it is also a natural site of weakness, which is why inguinal hernias are so common.

An inguinal hernia does not heal on its own. The weakness in the abdominal wall does not close again, and the bulge tends to slowly enlarge over months or years. Repair requires surgery.

Types of Inguinal Hernia

Doctors describe two main types based on exactly where the tissue pushes through:

Indirect inguinal hernia. This is the more common type. It happens when tissue pushes through the inguinal canal along the same path the testicle travelled during fetal development. Indirect hernias are often related to a small opening that was present from birth, even if the bulge only appears decades later. They can extend down into the scrotum in men.

Direct inguinal hernia. This type happens when tissue pushes directly through a weakened area of the abdominal wall, rather than along the canal. Direct hernias are more common in older adults and develop because the muscle and connective tissue have weakened over time.

Hernias can also be described as:

• Reducible — the bulge can be pushed back into the abdomen, often when you lie down
• Irreducible or incarcerated — the bulge is stuck and cannot be pushed back
• Strangulated — the trapped tissue has lost its blood supply, which is a surgical emergency
• Bilateral — hernias on both sides
• Recurrent — a hernia that has come back after previous repair

Why Is Inguinal Hernia Repair Performed?

Repair is offered to relieve symptoms, restore normal activity, and prevent serious complications.

The most pressing reason to repair a hernia is the small but real risk of incarceration (the hernia getting stuck) and strangulation (the trapped tissue losing its blood supply). Strangulation is a surgical emergency and can lead to death of the trapped intestine, requiring more complex surgery and a longer recovery. While the yearly risk of this happening is low for any individual hernia, the risk is lifelong and tends to be higher for certain hernia types, including femoral hernias and hernias that have become difficult to push back.

Other reasons your surgeon may recommend repair include:

• Pain or discomfort that affects daily activities, work, or exercise
• A bulge that is enlarging
• A hernia that affects the scrotum or causes a dragging sensation
• A hernia in someone who does heavy lifting at work
• A hernia in someone who plans to start an exercise programme

For a small, soft, easily reducible hernia that causes few or no symptoms in an adult, some surgeons may discuss watchful waiting — monitoring the hernia rather than operating immediately. Studies have shown that for men with minimal symptoms, watchful waiting is reasonably safe in the short term, although most men eventually have surgery because symptoms develop over time. The European Hernia Society and other major hernia societies suggest that the decision between early repair and watchful waiting depends on symptoms, hernia features, the patient’s general health, and personal preference.

Who Is a Candidate for Repair?

Most adults with a symptomatic inguinal hernia are candidates for surgery. The questions your surgeon will consider include:

• How much the hernia is bothering you and limiting your activities
• Whether the hernia can be pushed back in, or whether it sometimes gets stuck
• Whether the hernia is on one side or both sides
• Whether this is a first-time repair or a recurrence after previous surgery
• Your overall health and any other medical conditions
• Whether you can safely have general anaesthesia, or whether spinal or local anaesthesia would be better
• Your weight, fitness, and any habits such as smoking that affect healing

People with significant heart or lung disease, uncontrolled diabetes, bleeding disorders, or active infections may need their condition optimised before elective surgery. Your surgeon and anaesthetist will work with you on this before scheduling the operation.

Alternatives to Surgery

Inguinal hernia is a mechanical problem — a hole or weakness in the abdominal wall — and surgery is the only treatment that closes the defect. There is no medication or exercise that repairs a hernia. However, the following non-surgical options may have a role in specific situations:

Watchful waiting. As described above, this is an option for adult men with small, soft, minimally symptomatic hernias who understand the risks and accept ongoing follow-up. It is not appropriate for women (who have a higher rate of femoral hernia, which carries a greater risk of strangulation), for hernias that have become difficult to reduce, or for symptomatic hernias.

Trusses or supportive garments. A truss is a belt-like device that puts pressure on the hernia to keep it inside. It does not heal the hernia and is not a long-term solution. It may be used temporarily for someone who cannot have surgery, but it can be uncomfortable and does not reduce the risk of incarceration or strangulation in any meaningful way.

Lifestyle measures. Avoiding heavy lifting, treating chronic cough, managing constipation, and losing weight if needed can reduce strain on the abdominal wall and may slow worsening. They do not repair the hernia.

For a hernia that is causing symptoms, surgery remains the only treatment that addresses the underlying problem.

Surgical Approaches

Inguinal hernia repair can be performed through several different approaches. The choice depends on the type of hernia, whether it is on one or both sides, whether it is a first-time or recurrent hernia, the patient’s general health, the surgeon’s expertise, and the facilities available. Major hernia societies, including the international HerniaSurge group, describe both open and minimally invasive approaches as acceptable, and emphasise that surgeon experience with the chosen technique strongly influences outcomes.

Open Repair

In an open repair, the surgeon makes a single incision (usually 5 to 10 cm) in the groin over the hernia. The hernia sac and its contents are gently pushed back into the abdomen, and the weakened abdominal wall is reinforced.

The most widely used open technique uses a piece of synthetic mesh to reinforce the abdominal wall, often referred to as the Lichtenstein repair. The mesh is stitched into place over the weakened area. Over time, the body grows tissue into the mesh, creating a strong, durable repair.

Open repair without mesh, called tissue repair or suture repair, uses the patient’s own tissue, stitched together to close the defect. The Shouldice technique is the best-known tissue repair. Tissue repair has higher recurrence rates than mesh repair in most settings and is now used selectively — for example, when mesh is contraindicated or when a surgeon with specific expertise in tissue repair offers it.

Open repair can be performed under general anaesthesia, spinal anaesthesia, or sometimes local anaesthesia with sedation. This flexibility makes it suitable for patients who cannot safely have general anaesthesia.

Laparoscopic Repair

Laparoscopic repair is a minimally invasive approach. The surgeon makes three small incisions (each around 5 to 10 mm) in the lower abdomen and uses a thin camera and long instruments to perform the repair from inside. The mesh is placed behind the abdominal wall, where the body’s own pressure helps hold it in position.

There are two main laparoscopic techniques:

• Totally extraperitoneal (TEP) repair, in which the surgeon works in the space between the abdominal wall and the lining of the abdomen, without entering the abdominal cavity itself
• Transabdominal preperitoneal (TAPP) repair, in which the surgeon enters the abdominal cavity, identifies the hernia from the inside, and places the mesh in the same plane behind the abdominal wall

Laparoscopic repair is often favoured by surgeons for hernias on both sides at the same time (because both can be repaired through the same small incisions), for recurrent hernias after previous open repair (because the surgeon works through fresh tissue planes rather than scar), and for patients who want a quicker return to activity. It requires general anaesthesia and a surgeon trained specifically in laparoscopic hernia techniques.

Robotic Repair

Robotic inguinal hernia repair is a form of minimally invasive surgery in which the surgeon controls robotic instruments from a console. The mesh placement and repair principles are similar to laparoscopic TAPP repair, but the robotic platform offers magnified three-dimensional vision and wristed instruments that can move with greater precision. The patient experience — small incisions, mesh repair, similar recovery — is similar to laparoscopic surgery.

Robotic repair is most often used for complex, recurrent, or bilateral hernias, or in centres where the platform is routinely available. Current evidence suggests that for straightforward primary inguinal hernias, robotic and laparoscopic repair produce broadly similar outcomes; robotic surgery tends to take longer in the operating room.

Mesh vs No Mesh

The use of mesh has changed inguinal hernia repair over the past few decades. Major hernia societies describe mesh repair as the standard approach for adult inguinal hernias because recurrence rates are lower than with tissue-only repair. Modern meshes are made from synthetic materials (usually polypropylene) that are well tolerated by the body. A small number of patients develop mesh-related issues such as chronic pain or, very rarely, infection; your surgeon will discuss these risks.

Tissue repair without mesh remains an option in specific situations and is the standard approach for inguinal hernia repair in children, where mesh is not used.

Preparing for Inguinal Hernia Repair

Once you and your surgeon decide to proceed with repair, you will be guided through a series of preparation steps over the days or weeks before surgery.

Medical Evaluation

You will have a pre-operative assessment, which usually includes:

• A review of your medical history, current medications, allergies, and any previous surgeries
• A physical examination
• Routine blood tests
• An electrocardiogram (ECG) if you are over a certain age or have heart concerns
• A chest X-ray in some cases
• A meeting with an anaesthetist to discuss the type of anaesthesia and any specific concerns

If you have other medical conditions — diabetes, high blood pressure, heart or lung disease — these will be optimised before surgery.

Lifestyle Preparation

In the weeks leading up to surgery, your surgical team may advise:

• Stopping smoking. Smoking impairs wound healing and increases the risk of chest complications and hernia recurrence. Even a few weeks of cessation before surgery helps.
• Weight management. If your weight is high, losing some weight reduces strain on the abdominal wall and improves the technical conditions for surgery.
• Treating constipation and chronic cough. Both increase abdominal pressure. Your doctor may recommend laxatives, stool softeners, or treatment for your cough before surgery.
• Optimising blood sugar if you have diabetes.

Medications

Your surgeon will review your medications and tell you which to continue, pause, or adjust. Blood thinners (such as warfarin, clopidogrel, or apixaban) usually need to be stopped or bridged before surgery under your doctor’s guidance. Some diabetes medications and herbal supplements may also need to be paused.

The Day Before and Day of Surgery

• You will be told when to stop eating and drinking, usually from midnight before surgery
• You may be asked to shower with a special antiseptic soap
• Hair removal in the surgical area, if needed, is usually done in the hospital with clippers, not razors
• Bring a list of your medications, any imaging or test reports, and comfortable loose clothing for going home
• Arrange for someone to drive you home and stay with you for the first night

What Happens During Surgery

The exact steps depend on whether you have open or minimally invasive surgery, but the overall flow is similar.

Anaesthesia

You will meet the anaesthetist before going into the operating room. Depending on the planned approach and your health, you will have:

• General anaesthesia — you are completely asleep, with a breathing tube in place. Required for laparoscopic and robotic surgery.
• Spinal anaesthesia — an injection in the lower back numbs you from the waist down; you can be awake or lightly sedated. An option for some open repairs.
• Local anaesthesia with sedation — the surgeon injects numbing medicine around the surgical area; you are awake but relaxed. An option for selected open repairs.

The Operation

1. The surgical area is cleaned and draped
2. The surgeon makes either a single groin incision (open) or several small incisions (laparoscopic or robotic)
3. The hernia sac is identified and separated from surrounding structures, including the spermatic cord in men
4. The contents of the hernia (intestine, fat, or other tissue) are gently pushed back inside the abdomen
5. A piece of mesh is positioned to cover the weakened area
6. The mesh is fixed in place with stitches, tacks, or surgical glue, or is held in place by the surrounding tissue
7. The incisions are closed with stitches that usually dissolve, and a dressing is applied

Most inguinal hernia repairs take between 45 minutes and 90 minutes. Bilateral repairs and complex or recurrent cases take longer.

After the Operation

You will wake up in a recovery area where nurses monitor your vital signs and pain. Most people are awake and reasonably alert within an hour. Many inguinal hernia repairs are performed as day surgery, with discharge later the same day. Some patients stay one night, particularly if surgery is in the evening, if there were complicating factors, or if pain control needs more time.

Recovery and Healing

The First Few Days

Expect some pain, swelling, and bruising in the groin and sometimes in the scrotum in men. Pain is usually mild to moderate and well controlled with paracetamol and a short course of stronger pain medication. Most people:

• Walk on the day of surgery, even if slowly
• Eat a normal diet within 24 hours, starting with light foods
• Shower after 24 to 48 hours, depending on the dressing used
• Manage pain with a combination of regular paracetamol and an anti-inflammatory medication if not contraindicated

You may notice a firm lump under the incision; this is normal scar tissue and settles over weeks.

The First Two Weeks

Pain typically improves day by day. Bruising fades. People with desk-based work often return after one to two weeks. Driving can usually be resumed once you can comfortably perform an emergency stop without pain — often after one to two weeks.

Weeks Two to Six

Activity is gradually built back up. Most surgeons advise avoiding heavy lifting (typically more than 5 to 10 kg, or whatever your surgeon specifies) for around four to six weeks to give the repair time to integrate with the surrounding tissue. Walking, gentle stretching, and light cardiovascular exercise are usually encouraged earlier.

Return to Specific Activities

• Desk-based work: often 7 to 14 days
• Light manual work: 2 to 4 weeks
• Heavy manual work or contact sports: 4 to 6 weeks, sometimes longer, depending on the job and the surgeon’s advice
• Sexual activity: when comfortable, usually after 1 to 2 weeks
• Air travel: short flights after about a week; longer flights after two weeks, with attention to blood clot prevention

These are general patterns. Your own timeline depends on the type of surgery, the type of hernia, your job, and how you heal. Your surgeon will give you personalised advice.

Wound Care and Follow-up

Keep the dressing dry until your surgeon says otherwise. Most stitches dissolve and do not need removal. You will have a follow-up visit at one to four weeks to check the wound and confirm healing. Contact your surgical team if you develop fever, increasing redness or pain at the incision, pus discharge, a sudden new bulge, severe abdominal pain, vomiting, or difficulty passing urine.

Risks and Complications

Inguinal hernia repair is a very safe operation, but, like any surgery, it carries some risk. Most people experience few or no complications. The possibilities include:

Common, usually minor:

• Bruising and swelling of the groin and scrotum, which can look dramatic but usually settle in 2 to 4 weeks
• Seroma — a collection of clear fluid under the skin that usually reabsorbs over weeks
• Temporary numbness or altered sensation around the incision or in the upper thigh
• Constipation in the first days after surgery, often linked to pain medication

Less common:

• Wound infection — uncommon and usually treated with antibiotics
• Bleeding or haematoma that needs drainage
• Urinary retention — difficulty passing urine, usually short-lived
• Injury to nerves in the groin, leading to chronic discomfort or numbness

Uncommon but important:

• Chronic groin pain — persistent pain lasting beyond three months. Most patients have no chronic pain, but a minority experience some degree, ranging from mild to disabling. This is one of the most studied complications of hernia repair, and it can occur after any approach.
• Recurrence — the hernia coming back. With mesh repair by an experienced surgeon, recurrence rates are low.
• Injury to the spermatic cord, blood supply to the testicle, or vas deferens in men, which can rarely affect fertility or testicular size
• Mesh-related complications, including infection of the mesh (very rare) or, even more rarely, the mesh migrating or eroding into surrounding structures
• Injury to bowel, bladder, or blood vessels — very rare, more associated with laparoscopic approaches
• Anaesthesia-related complications, including reactions to medications and breathing complications
• Blood clots in the legs or lungs, which are reduced by early walking and, when needed, blood thinning medication

Your surgeon will discuss your individual risk profile based on your age, health, the type of hernia, and the chosen approach.

Life After Inguinal Hernia Repair

Most people make a full recovery and return to their previous level of activity, including sports and physical work, within six to twelve weeks. The repaired area continues to strengthen as scar tissue matures over the following months.

Long-Term Outlook

Mesh-based inguinal hernia repair is a durable operation. The large majority of patients have no recurrence and no significant ongoing symptoms. Some practical points to keep in mind:

• You may continue to feel a firm or slightly tender area in the groin for several months. This is normal as the body integrates the mesh.
• Air travel security scanners are not affected by surgical mesh.
• The repair does not affect normal sexual function in the long term.
• In men, the operation does not affect testosterone or fertility for the vast majority, although rare complications can.

Reducing the Risk of Another Hernia

Once you have had an inguinal hernia, you have a somewhat higher chance of developing a hernia on the other side or another hernia elsewhere in the abdominal wall in the future. Reasonable habits include:

• Maintaining a healthy weight
• Not smoking
• Treating chronic cough and constipation
• Using safe lifting techniques — lifting with the legs, not the back, and avoiding holding your breath while straining
• Building general core strength gradually

If you notice a new bulge, new groin discomfort, or recurrence of the original symptoms, see your surgeon for evaluation.

Inguinal Hernia Repair in Children

Inguinal hernias in children are managed differently from those in adults.

In babies and young children, inguinal hernias are almost always indirect and result from a small passage that did not close during fetal development. They are particularly common in premature babies. Unlike adults, children’s hernias are repaired soon after diagnosis because the risk of incarceration is higher in this age group, particularly in infants.

Paediatric inguinal hernia repair is usually a short operation in which the surgeon ties off the small sac through which tissue is protruding (called high ligation of the hernia sac). Mesh is not used in children because the abdominal wall is still growing. The operation can be performed open or laparoscopically; both produce excellent results in experienced hands. Surgery is performed under general anaesthesia, and most children go home the same day. Recovery is typically quick, with most children back to normal activity within a week.

Parents should look out for signs of incarceration in a child with a known or suspected hernia: a bulge that does not go away when lying down, a hard or red lump in the groin or scrotum, vomiting, severe distress, or refusal to feed. These need urgent medical assessment.

Frequently Asked Questions

Can an inguinal hernia heal on its own?

No. An inguinal hernia is a mechanical defect in the abdominal wall. It does not heal without surgery. Lifestyle measures may reduce symptoms but do not close the hole.

Is mesh safe?

Synthetic mesh has been used in inguinal hernia repair for decades and is considered safe by major hernia societies. It substantially reduces recurrence compared with tissue-only repair. Mesh-related complications such as chronic pain or mesh infection can occur but are uncommon. Your surgeon will discuss the specific mesh planned and its track record.

Open or laparoscopic — which is better?

For a first-time, one-sided inguinal hernia, both open and laparoscopic repair give good results when performed by experienced surgeons. Laparoscopic repair often has less pain in the first days and a faster return to activity, while open repair can be done under spinal or local anaesthesia and may be preferred for patients who cannot have general anaesthesia. For hernias on both sides at the same time, or for hernias that have come back after open repair, surgeons often favour a laparoscopic approach. The best choice for you depends on your situation and your surgeon’s expertise.

Will I need general anaesthesia?

Laparoscopic and robotic repairs require general anaesthesia. Open repair can sometimes be performed under spinal or local anaesthesia with sedation, which is useful for patients with significant heart or lung conditions. Your anaesthetist will recommend the safest option for you.

How soon can I drive after surgery?

Most people can drive again within one to two weeks, once they can comfortably perform an emergency stop without pain and are no longer taking strong pain medication that could affect alertness.

When can I lift heavy weights again?

Most surgeons advise avoiding heavy lifting for four to six weeks. After that, you can gradually return to your previous level. If your job involves heavy lifting, your surgeon may extend this period. Building up gradually is generally safer than returning to maximum loads at once.

Will the hernia come back?

Recurrence is uncommon after modern mesh-based repair, particularly when performed by an experienced surgeon. Following the activity advice in the first weeks, not smoking, treating chronic cough or constipation, and maintaining a healthy weight all reduce the risk.

Will surgery affect my fertility or sexual function?

For the vast majority of men, inguinal hernia repair does not affect fertility, testosterone, or sexual function. Rare complications involving the vas deferens or blood supply to the testicle can occur. Your surgeon will explain the specific risks based on your anatomy and the planned approach.

What if I have hernias on both sides?

Bilateral hernias can be repaired during the same operation. Laparoscopic and robotic approaches are often favoured for bilateral repairs because both sides can be addressed through the same small incisions.

Can I delay surgery?

For a small, soft, easily reducible hernia with minimal symptoms in an adult, your surgeon may discuss watchful waiting. For symptomatic hernias, hernias that are difficult to reduce, hernias in women, and femoral hernias, repair is generally advised because the risk of complications is higher. Delaying surgery does not make it easier later, and emergency surgery for a strangulated hernia carries more risk than planned repair.

Conclusion

Inguinal hernia repair is a well-established operation with predictable outcomes. The modern combination of mesh-based repair, minimally invasive options, and refined anaesthesia means that most people recover quickly, return to normal activities within weeks, and have a durable result that lasts for years.

The decisions in front of you — whether to repair now or wait, open or laparoscopic or robotic, mesh or no mesh — depend on your specific hernia, your health, your work and lifestyle, and your surgeon’s experience. Walking into that conversation understanding the landscape, the options, and the realistic recovery picture makes it easier to plan the operation around the rest of your life.
