Paraumbilical and Umbilical Hernia Repair

CQC Good RatedConsultant-Led CareAll-Inclusive PricingNo GP Referral0% Finance Available

A hernia in the belly button area is one of the most common types of abdominal wall hernia. An umbilical hernia occurs when tissue pushes through the umbilicus (the belly button itself), while a paraumbilical hernia occurs through a weakness in the tissue immediately next to it. You may notice a soft bulge that appears when you stand up, cough, or strain.

These hernias are common in women, particularly after pregnancy, and in people who are overweight. While some are small and cause few problems, they can gradually enlarge and may become painful or at risk of incarceration. At Kinvara Private Hospital, we offer expert surgical repair as a day case procedure.

The navel is a natural weak point in the abdominal wall, being the site where the umbilical cord was attached before birth. In adults, this area can weaken due to increased abdominal pressure from factors like obesity, pregnancy, heavy lifting, or persistent coughing.

Surgical repair is a straightforward and highly effective procedure. For small hernias, the defect can be closed with strong sutures. For larger hernias, a synthetic mesh is used to reinforce the repair and significantly reduce the risk of recurrence. Most patients go home on the same day as their surgery and can return to normal activities within a few weeks.

Diagnosis and Assessment

Diagnosing an umbilical or paraumbilical hernia is usually straightforward. Your surgeon will examine your abdomen while you are standing and lying down, and will ask you to cough or strain to make the bulge more prominent. They will feel the size of the defect in the abdominal wall and whether the hernia contents can be pushed back in (reducible).

For most patients, a clinical examination is all that is needed. If there is any uncertainty, or if your surgeon wants to assess the hernia contents, an ultrasound scan may be arranged. Before your surgery, you will have a pre-operative assessment to ensure you are fit for anaesthesia.

Understanding Umbilical and Paraumbilical Hernias

The umbilicus (belly button) is the scar left after the umbilical cord detaches at birth. It represents a natural weak spot in the abdominal wall. In some cases, this area fails to close completely, or it weakens over time, allowing the underlying fatty tissue or intestine to bulge through. A true umbilical hernia occurs directly through the umbilical ring, while a paraumbilical hernia occurs through a weakness in the linea alba (the midline fibrous tissue) just above or below the navel. In practice, the two are often treated similarly.

These hernias are common, affecting around 2% of adults. They are more prevalent in women (especially after pregnancy) and in individuals who are overweight. While small hernias may remain stable for many years, they can slowly enlarge and are at risk of incarceration, where the contents become trapped and painful. Strangulation, where the blood supply is cut off, is a surgical emergency.

Benefits of Surgery at Kinvara

  • Rapid access to experienced consultant surgeons
  • Day case surgery – go home the same day
  • Cosmetically concealed incision at the navel
  • Low recurrence rates with mesh repair for larger hernias
  • Quick return to normal daily activities

Why Do These Hernias Develop?

The primary cause is increased pressure within the abdomen acting on a weakened area of the abdominal wall. Factors that increase this pressure include:

- Pregnancy: Multiple pregnancies stretch the abdominal wall and can weaken the tissue around the navel.
- Obesity: Excess body weight places constant strain on the abdominal wall.
- Heavy lifting: Repetitive strain can push tissue through a weak point.
- Chronic cough: Persistent coughing (e.g., from smoking or lung conditions) increases abdominal pressure.
- Ascites: Fluid accumulation in the abdomen (e.g., from liver disease) stretches the abdominal wall.
- Constipation: Straining during bowel movements.

Some people may also have a congenital predisposition to a weaker umbilical area.

Surgical Repair Options

Conservative Management

Unlike umbilical hernias in infants (which often close spontaneously), adult umbilical and paraumbilical hernias will not resolve on their own. A supportive abdominal binder may provide temporary symptom relief but is not a treatment. Surgical repair is recommended for all symptomatic hernias and for asymptomatic hernias that are enlarging or have a narrow neck (which increases the risk of incarceration).

Surgical Options

The surgery is performed under general anaesthesia, usually as a day case. An incision is made at the navel (often concealed within the skin folds for a better cosmetic result). The hernia sac is opened, its contents reduced back into the abdomen, and the sac is removed. The defect in the abdominal wall is then repaired.

- Suture repair: For small defects (typically less than 2cm), the edges of the muscle and fascia can be stitched together directly.
- Mesh repair: For larger defects, a piece of synthetic mesh is placed to bridge the gap and reinforce the repair. This significantly reduces the risk of recurrence. The mesh is typically placed behind the muscle (retromuscular or underlay position) or in front of it (onlay position).

The operation typically takes 30-60 minutes.
