Introduction

A hernia occurs when an internal part of the body pushes through a weakness in the muscle or surrounding tissue wall.

Your muscles are usually strong and tight enough to keep your intestines and organs in place, but a hernia can develop if there are any weak spots.

What is a femoral hernia?

A femoral hernia is an uncommon type of hernia. It's estimated that only about 1 in every 20 groin hernias are femoral hernias, and the rest are inguinal hernias .

Femoral hernias sometimes appear as a painful lump in the inner upper part ofthe thigh or groin. The lump can often be pushed back in ordisappears when you lie down. Coughing or straining may make the lump appear.

  • inguinal hernia
  • hiatus hernia
  • umbilical hernia

What causes a femoral hernia?

A femoral hernia usually occurs when fatty tissue or a part of your bowel pokes through into your groin at the top of your inner thigh.

It pushes through a weak spot in the surrounding muscle wall (abdominal wall) into an area called the femoral canal.

Unlike inguinal hernias, femoral hernias occur far more frequently in women, particularly older women. This is because of the wider shape of the female pelvis. Femoral hernias are rare in children.

Femoralhernias can sometimes appear suddenly because of strain on the abdomen, such as:

  • straining on the toilet if you have constipation
  • carrying and pushing heavy loads

They've also been linked to obesity and having a persistent, heavy cough.

Whenis surgery needed?

Femoral hernias can be repaired using surgery to push the bulge back into place and strengthen the weakness in the abdominal wall.

Unlike some other types of hernia, treatment of femoral hernias is almost always recommended straight away because there's a higher risk of complications developing in these cases.

Complications that can develop as a result of a femoral hernia include:

  • obstruction where a section of the bowel becomes stuck in the femoral canal, causing nausea, vomiting and stomach pain, as well as a painful lump in the groin
  • strangulation where a section of bowel becomes trapped and its blood supply is cut off; this requires emergency surgery within hours to release the trapped tissue and restore its blood supply, so it doesn't die

Surgery gets rid of the hernia and prevents any serious complications, although there's a chance of it returning after the operation.

What happensduringsurgery?

There are two ways a femoral hernia repair can be performed:

  • open surgery where one cut is made to allow the surgeon to push the lump back into the abdomen
  • laparoscopy (keyhole) surgery a less invasive, but more difficult, technique where several smaller cuts are made, allowing the surgeon to use various special instruments to repair the hernia

There are advantages and disadvantages to both methods. The type of surgery you have depends on which method suits you and your surgeons experience.

You should be able to go home the same day or the day after surgery. It's important to follow the hospital's instructions on how to look after yourself. This includes eating a good diet to avoid constipation, caring for the wound and not straining yourself too soon.

Most people make a full recovery from femoral hernia repair within six weeks, although many people can return to driving, work and light activities within two weeks.

Are there any risks from the operation?

Femoral hernia repair is a routine operation with very few risks, although around 1% ofhernias return after the operation.

Other uncommon complications of femoral hernia repair include:

  • developing a lump under the wound
  • difficulty passing urine
  • injury or narrowing of the femoral vein (which passes through the femoral canal)
  • injury to the bowel
  • temporary weakness of the leg
  • injury to the nerves, causing pain or numbness in the groin area

Complications are more likely if you're over 50 or have another illness, such as heart disease or breathing problems.
