Hernia Repair

Hernia repair is a surgical procedure that closes an abnormal opening in the muscle or tissue wall through which an internal organ or fatty tissue has pushed through.

A hernia forms when a weak spot develops in the muscular wall of the abdomen or groin, allowing soft tissue — usually part of the intestine or a pad of fat — to bulge through. This bulge can cause pain, discomfort, or dangerous complications if the trapped tissue loses its blood supply. During hernia repair, the surgeon pushes the bulging tissue back into its correct position and then reinforces the weakened wall, either by stitching the muscle edges together or by placing a small mesh patch (a thin, flexible net) over the weak spot to give it lasting support.

Hernia repair is recommended when a hernia causes symptoms, grows larger, or poses a risk of serious complications. The most common reason is pain or a noticeable bulge that interferes with daily life, but doctors also operate to prevent an emergency known as strangulation (when blood supply to the trapped tissue is cut off).

• Inguinal hernia (groin hernia) — the most common type, where tissue pushes through the lower abdominal wall into the groin or scrotum
• Femoral hernia — similar to inguinal but slightly lower, more common in women
• Umbilical hernia — tissue bulges through or near the belly button
• Incisional hernia — tissue pushes through the scar of a previous abdominal surgery
• Hiatal hernia — the upper part of the stomach slides up through the diaphragm (the breathing muscle) into the chest cavity
• Epigastric hernia — a bulge in the upper-middle area of the abdomen, between the belly button and the breastbone
• A hernia that is incarcerated (stuck and cannot be pushed back) or strangulated (blood supply cut off) — these are surgical emergencies

Surgery may not be immediately recommended in every case. Doctors sometimes take a watch-and-wait approach for hernias that are very small, cause no symptoms, and appear in patients whose overall health makes surgery risky. The decision is always made individually.

Like all surgical procedures, hernia repair carries some risks, though serious complications are uncommon. The risks listed below are recognised and discussed with patients before surgery.

• Pain or discomfort at the repair site, especially in the first days after surgery
• Bruising and swelling around the incision or in the groin and scrotum
• Wound infection (the area becoming red, warm, or producing discharge)
• Seroma (a pocket of clear fluid that collects under the skin near the repair site)
• Haematoma (a collection of blood under the skin that causes bruising and swelling)
• Temporary difficulty urinating, particularly after groin hernia repair
• Numbness or changed sensation in the skin near the incision due to nearby nerve irritation
• Hernia recurrence (the hernia returning at the same site, more common without mesh)
• Mesh-related complications such as migration (the mesh shifting from its original position) or chronic pain in a small number of patients
• Injury to nearby structures — including the bladder, blood vessels, or the vas deferens (the tube that carries sperm) — which is rare
• Risks related to general anaesthesia (the medicine that keeps you deeply asleep), including allergic reaction or breathing difficulties

Good preparation helps the surgery go safely and smoothly. Your surgical team will give you specific instructions, but the following covers what is typically expected.

In the days before surgery, patients are usually asked to stop smoking and avoid alcohol, as both slow healing and increase anaesthesia risks. Anyone taking blood thinners, anti-inflammatory painkillers, or certain supplements will usually be advised to pause them for a set period beforehand — the surgical team will specify which ones. Fasting (no food or drink, including water) is required for a period before general anaesthesia; your team will tell you the exact cut-off time.

Pre-operative tests are commonly ordered to make sure the patient is fit for surgery. These may include:

• Blood tests to check overall health and clotting ability
• An ECG (electrocardiogram, a recording of the heart's electrical activity) to assess heart function
• A chest X-ray in some patients
• An ultrasound (USG) or CT scan to confirm the hernia's size and exact location if the diagnosis is unclear

On the day of surgery, the procedure generally follows these steps:

• 1. The patient is admitted and identity, allergy, and consent details are confirmed.
• 2. An intravenous (IV) line is placed in the arm to deliver fluids and medications.
• 3. Anaesthesia is given — this is usually general anaesthesia, though some groin repairs are done under regional (spinal) anaesthesia (numbing from the waist down).
• 4. The surgeon makes one or more incisions. In open surgery, a single larger cut is made directly over the hernia. In laparoscopic (keyhole) surgery, several small cuts are made and a thin camera is inserted to guide the repair.
• 5. The bulging tissue is gently moved back into the abdomen.
• 6. The weakened area is repaired — stitched closed and/or reinforced with a mesh patch.
• 7. The incisions are closed with stitches, staples, or adhesive strips.
• 8. The patient is moved to a recovery area where vital signs are monitored until the anaesthesia wears off.

Recovery from hernia repair varies depending on the surgical approach (open or laparoscopic), the hernia's location and size, and the patient's general health. Most patients who have laparoscopic repair go home the same day or the day after; open repair may require a slightly longer stay. Your medical team will decide when it is safe to discharge you.

• Pain management: Some pain and soreness around the repair site is normal for the first week or two. The team will advise on appropriate pain relief.
• Activity restrictions: Heavy lifting and strenuous exercise are usually avoided for several weeks. Walking is encouraged early to reduce the risk of blood clots (clots that form in the veins).
• Wound care: The incision area should be kept clean and dry. Stitches may dissolve on their own or need to be removed at a follow-up visit — the team will clarify which type was used.
• Swelling and bruising: Swelling in the groin or around the belly button is common and usually settles within a few weeks. Scrotal swelling after groin repair can take longer to resolve.
• Driving: Most patients are advised not to drive until they can perform an emergency stop comfortably without pain — usually at least a week after surgery, but this varies.
• Return to work: Office-based or desk work may be possible within one to two weeks for laparoscopic repair; physically demanding jobs may require a longer absence.
• Follow-up appointments: A follow-up visit is usually scheduled within the first few weeks to check the wound and confirm recovery is on track.
• Warning signs to report: Increasing pain, redness, warmth or discharge from the wound, fever, inability to urinate, or a new bulge at the repair site should be reported to the medical team promptly.
• Long-term lifestyle: Maintaining a healthy weight, avoiding chronic straining (such as from constipation or heavy lifting), and managing any chronic cough can help reduce the chance of recurrence.
