Hernia Surgery

A hernia happens when an organ or fatty tissue pushes through a weak point in the surrounding muscle or connective tissue. The commonest type is the inguinal, or groin, hernia, which appears as a bulge low in the abdomen; umbilical hernias form at the navel, and incisional hernias appear along an old surgical scar where the wall did not fully heal. Other types include femoral, epigastric and hiatal hernias, the last involving the upper stomach sliding through the diaphragm. Hernias do not heal by themselves and usually enlarge with time. Surgery closes the gap and reinforces it, almost always with a soft mesh, so that the weak point is strong again and the contents stay where they belong.

Not every hernia needs immediate surgery, but planned repair is advised when a hernia causes ongoing pain or discomfort, grows steadily, limits activity, or becomes harder to push back in. Repairing a hernia while it is still small is generally simpler with a better result than waiting until it enlarges. Urgent surgery is needed if a hernia becomes trapped and its blood supply is cut off, a situation called strangulation, which causes sudden severe pain, a firm tender bulge that will not go back, redness, fever and vomiting and must be treated without delay. For most adults with a symptomatic groin or abdominal hernia, elective repair is the recommended and definitive solution.

Hernia repair can be done by keyhole (laparoscopic) surgery or by open surgery, both reinforcing the defect with mesh. In the keyhole approach the surgeon makes two or three incisions of about half a centimetre to a centimetre, inserts a camera and slim instruments, and places a mesh over the weak area from the inside of the wall, where it is held in place and gradually grows into the tissue. Both sides can be repaired in one sitting when groin hernias are present on each side. The open approach uses a single small incision directly over the hernia and is a good choice in certain cases. For complex or recurrent hernias, a robotic platform can give the surgeon fine control for precise mesh placement and suturing. Most repairs are done under general anaesthesia and take roughly 45 minutes to 1.5 hours.

A good candidate is anyone with a hernia that warrants repair and who is fit for anaesthesia. The assessment confirms the type, size and position of the hernia by examination and, where helpful, an ultrasound or scan, and checks general health. Routine blood tests and, where appropriate, a heart trace confirm fitness for surgery. Stopping smoking, reaching a stable weight and good control of conditions such as a chronic cough or constipation all help the repair last, since they reduce strain on the wall. Blood-thinning medicines are paused beforehand on medical advice. For international patients, the diagnosis and any imaging can be reviewed remotely before travel, so the plan is agreed in advance and the operation can proceed soon after arrival.

Most patients go home the same day or after one night. The small incisions are closed with dissolving stitches and heal within one to two weeks; mild soreness around them is normal and is managed with simple painkillers. Walking and light activity are encouraged from the day after surgery, and most people return to desk work within about a week. Heavy lifting and strenuous exercise are avoided for four to six weeks while the mesh becomes firmly integrated into the tissue. Planning a trip abroad, it is sensible to stay in the destination city for about 3 to 7 days, so the wounds can be checked and early healing confirmed before flying. Air travel is comfortable once the surgeon gives the go-ahead at that check. Follow-up afterwards continues remotely by message, photo or video, with interpreter support available throughout.

In experienced hands and a proper hospital setting, hernia repair is a safe and highly successful operation, though, like any surgery, it carries some risk. Common, temporary effects include bruising, mild swelling at the site, and a feeling of tightness that eases as healing progresses. Less common risks include wound infection, a collection of fluid that usually settles on its own, temporary numbness near the incision, and, uncommonly, a return of the hernia, which mesh repair makes much less likely than stitch-only methods. The mesh itself becomes part of the body over time and causes no problems in the great majority of patients. With a successful repair, the bulge is gone, comfort is restored, and after a few weeks of healing there is no restriction on normal life.
