Hernia Repair
A hernia occurs when an internal part of the body pushes through a weak spot in the surrounding muscle or tissue wall. Abdominal hernias occur when a weakness in the wall of the tummy (abdominal wall) results in some of the contents in the abdominal cavity bulging through. Most hernias need treating by performing an operation. There are now various different types of operation, which are usually very successful.
What are the symptoms of a Hernia?
Sometimes a hernia is noticed after a strain - for example, after lifting a heavy object. Sometimes one may develop for no good reason and you may simply notice a small lump, usually in the groin area. Usually, at first, the lump can be pushed back but may pop out after straining again. Coughing is a common strain that brings them out. The swelling often disappears when you lie down. Hernias are not usually painful but many people feel an ache over a hernia, which worsens after doing any activity. In time, they might become bigger as the gap in their muscle or ligament tissue becomes larger. Sometimes, in men, they track down into the scrotum.
What are the types of hernia?
The most common types are shown here:Inguinal hernia
This is the most common type. They are more likely in males, as they have a small tunnel in the tissues of their groins which occurred when they were developing as a baby. This tunnel allowed the testicles (testes) to come down from the tummy (abdomen) into the scrotum. Tissue from the intestines can also pass into this tunnel, forming an inguinal hernia. There are two main types:Femoral hernia
This also occurs when some tissue pushes through in the groin. It occurs a little lower down than where an inguinal hernia occurs, and it tends to be smaller. It occurs more commonly in women.Incisional hernia
This occurs when tissue pushes through a previous scar or wound. It is more common if you have had a scar in the past that has not healed well. For example, if the wound had an infection after the operation. It usually occurs within two years of having an operation.Umbilical and paraumbilical hernias
These occur when some tissue pushes through the abdomen near to the belly button (umbilicus). Umbilical hernias can be present from birth and in most cases the hernia goes back in and the muscles re-seal on their own before the baby is 1 year old. They will generally be repaired if they persist beyond 5 years of age or if they are very large. Umbilical hernias may develop in adults with being overweight (obesity) and excessive accumulation of fluid within the peritoneum of the abdomen. The peritoneum is a lining of the abdomen and consists of two layers, one which lines the abdominal wall and the other which covers the organs in the abdomen. Paraumbilical hernias occur in adults and appear above the umbilicus. Although they are generally small, they usually need repairing because there is a risk of intestines contained within them becoming strangulated.How are hernias repaired with surgery?
A small operation is recommended. Wearing a support (truss) was a method used in the past but is now not recommended.
The operation is one of the most common operations performed by surgeons. The repair can usually be performed as a day case so that there is no need to stay overnight in hospital. A hernia can either be repaired under a local or a general anaesthetic. This will depend on the actual type of operation needed. There are now various different ways of repairing a hernia, which will depend on many factors. For example, the type of hernia, the size of the hernia, and your general health. Your surgeon will be able to discuss the type of operation with you in more detail.
