WHAT IS A HERNIA?

A hernia occurs when there is a weakness or defect in the abdominal wall, allowing tissue or abdominal contents to push through and form a visible bulge. Hernias may develop after heavy lifting or straining, although sometimes there is no obvious cause. They often enlarge over time and may cause discomfort or pain, especially with lifting, exercise or coughing.

​

Occasionally, a hernia can become trapped and cannot be pushed back in. If this causes a painful, tense lump, urgent medical attention is required, as this may represent a surgical emergency.

​

Common types of abdominal hernia include inguinal hernia, umbilical hernia and incisional hernia.

​

INGUINAL HERNIA

An inguinal hernia occurs in the groin and is the most common type of abdominal hernia. It may gradually enlarge, occur on one or both sides, and cause discomfort with exercise or exertion.

​

Repair is usually performed under general anaesthetic as a Day-stay procedure. The hernia is reduced and the weakened area is strengthened, usually with a synthetic mesh. Mesh repair is standard modern practice and provides a strong, durable repair.

​

Inguinal hernia repair can be performed using either an open or laparoscopic (keyhole) approach. Both techniques have good long-term results. The Laparoscopic technique uses small incisions and may allow faster recovery, less wound discomfort and a lower risk of chronic groin pain in selected patients. Tauranga hernia repair specialist Peter Chin is trained in both open and laparoscopic inguinal hernia repair and will advise which approach is most suitable for you.

​

After surgery, the wound is usually covered with a waterproof dressing, which can be removed after 7 days. The stitches are dissolvable. Regular pain relief is recommended for the first few days, and gentle walking is encouraged.

 

Heavy lifting and strenuous activity should be avoided initially, with a gradual return to normal activity over the following weeks. Many people return to light work within 1–2 weeks, depending on comfort and the type of work.

​

UMBILICAL HERNIA

An umbilical hernia occurs at the belly button. The defect is often small but may enlarge over time and become uncomfortable.

Repair is usually performed as a day-stay procedure. The hernia is reduced and the defect is usually repaired with a mesh to strengthen the area. You should be able to return to light work within 2 weeks, depending on comfort and the nature of the activities.

​

INCISIONAL HERNIA

An incisional hernia develops through a weakness in the abdominal wall from previous surgery, usually along an old scar. These hernias can range from small defects to larger, more complex hernias.

​

Repair usually involves strengthening the weakened area with mesh. Depending on the size and complexity of the hernia, surgery may be performed as a straightforward day-stay procedure or may require a longer hospital stay. Peter will discuss the most appropriate option for your situation.
