Hernia

What is a hernia?

A hernia occurs when an internal organ or other body part protrudes through the wall of muscle or tissue that normally contains it. Most hernias occur within the abdominal cavity, between the chest and the hips.

The most common forms of hernia are:

• Inguinal hernia: In men, the inguinal canal is a passageway for the spermatic cord and blood vessels leading to the testicles. In women the inguinal canal contains the round ligament that gives support for the womb. In an inguinal hernia, fatty tissue or a part of the intestine pokes into the groin at the top of the inner thigh. This is the most common type of hernia and affects men more often than women.
• Femoral hernia: Fatty tissue or part of the intestine protrudes into the groin at the top of the inner thigh. Femoral hernias are much less common than inguinal hernias and affect mainly older women.
• Umbilical hernia: Fatty tissue or part of the intestine pushes through the abdomen near the navel (belly button).
• Hiatal (hiatus) hernia: Part of the stomach pushes up into the chest cavity through an opening in the diaphragm (the horizontal sheet of muscle that separates the chest from the abdomen).

Other types of hernias include:

• Incisional hernia: Tissue protrudes through the site of an abdominal scar from a remote abdominal or pelvic operation.
• Epigastric hernia: Fatty tissue protrudes through the abdominal area between the navel and lower part of the sternum (breastbone).
• Spigelian hernia: The intestine pushes through the abdomen at the side of the abdominal muscle, below the navel.
• Diaphragmatic hernia: Organs in the abdomen move into the chest through an opening in the diaphragm.

What are the symptoms of a hernia?

A hernia in the abdomen or groin can produce a noticeable lump or bulge that can be pushed back in, or that can disappear when lying down. Laughing, crying, coughing, straining during a bowel movement, or physical activity may make the lump reappear after it has been pushed in. More symptoms of a hernia include:

• Swelling or bulge in the groin or scrotum (the pouch that contains the testicles)
• Increased pain at the site of the bulge
• Pain while lifting
• Increase in the bulge size over time
• A dull aching sensation
• A sense of feeling full or signs of bowel obstruction.

In the case of hiatal hernias there are no bulges on the outside of the body. Instead, symptoms may include heartburn, indigestion, difficulty swallowing, frequent regurgitation, and chest pain.

How is a hernia diagnosed?

It is usually possible to see or feel a bulge in the area where a hernia has occurred by physical exam. Part of a male's typical physical exam for inguinal hernias includes the doctor feeling the area around the testicles and groin while the patient is asked to cough. In some cases, soft-tissue imaging like a CT scan will accurately diagnose the condition.

What causes a hernia?

Inguinal and femoral hernias are due to weakened muscles that may have been present since birth or are associated with aging and repeated strains on the abdominal and groin areas. Such strain may come from physical exertion, obesity, pregnancy, frequent coughing, or straining on the toilet due to constipation.

Umbilical hernias may be caused by straining the abdominal area, being overweight, having a long-lasting heavy cough, or after giving birth.

The cause of hiatal hernias is not fully understood but a weakening of the diaphragm with age or pressure on the abdomen could play a part.How is a hernia treated?

Hernias typically do not resolve on their own and surgery may be the only way to repair them.

In the case of an umbilical hernia in a child, surgery may be recommended if the hernia is large or if it has not healed by the age of 4 - 5 years old. By this age, a child can usually avoid surgical complications.

If an adult has an umbilical hernia, surgery is usually recommended because the condition will not likely improve on its own and the risk of complications is higher.

Cleveland Clinic Abu Dhabi’s comprehensive Hernia Surgery Program offers the following interventions for hernia repair:

• Laparoscopic surgical hernia repair: A minimally invasive surgery that uses a few tiny incisions (one to two centimeters long) and special instruments attached to the end of a thin flexible tube.
• Open surgical hernia repair: A traditional open surgical technique that uses one long incision (three to six inches long) to access the hernia. Though more invasive, this approach may be the best option for some patients.
• Robotic hernia repairs: A minimally invasive approach that uses robotic technologies to control instruments. This technology allows for greater dexterity and precision.
• Complex abdominal wall reconstruction: This surgery often requires repairing damage and defects acquired from previously failed surgeries. This type of surgery can be performed using open, laparoscopic, or robotic techniques.

Each type of surgery has its advantages and disadvantages. Our surgeons take a tailored approach to ensure the best possible outcome and assess each patient to select the most appropriate surgical technique.

What can happen if a hernia is not treated?

Other than umbilical hernias in babies, hernias will not disappear on their own. Over time, a hernia can grow larger and more painful or can develop complications.

Complications of an untreated inguinal or femoral hernia may include:

Obstruction (incarceration): Part of the intestine becomes stuck in the inguinal canal, causing nausea, vomiting, stomach pain, and a painful lump in the groin.

Strangulation: Part of the intestine is trapped in a way that cuts off its blood supply. In such cases, emergency surgery (within hours of occurring) is called for to prevent tissue death.

What can be expected following surgical treatment or a hernia?

After surgery, you will be given instructions. These include what diet to follow, how to care for the incision site, and how to take care to avoid physical strain. Hernias may recur regardless of the repair operations, sometimes this can be due to inherent tissue weakness or protracted healing. Smoking and obesity are also major risk factors for hernia recurrence.

How can a hernia be prevented?

• Maintain ideal body weight by eating a healthy diet and exercising.
• Eat enough fruits, vegetables, and whole grains to avoid constipation.
• Use correct form when lifting weights or heavy objects. Avoid lifting anything that is beyond your ability.
• See a doctor when you are ill with persistent coughs or sneezing.
• Don't smoke, as the habit can lead to coughing that triggers a hernia.

Our Hernia Surgery Program is comprised of experienced surgeons specialized in advanced laparoscopic and robotic procedures, as well as traditional open surgery and complex reconstructive surgery, for the treatment of abdominal wall and hernia conditions.
