General Surgery - Hernias
What is an abdominal wall hernia?
Your internal organs and tissues are held in place by a tough outer wall of tissue called the “abdominal wall.” An abdominal hernia is an area in that wall that is weak or torn. Often when there is a hernia, organs or tissues that are normally held in place by the abdominal wall bulge or stick out through the weak or torn spot.
Abdominal hernias may be present from birth (and slowly enlarge to the point when they are visible) or develop over time.
Where do they commonly occur?
- Groin ( Inguinal Hernia or Femoral Hernia)
- Through any previous surgical scar (Incisional Hernia)
- Bellybutton (Umbilical Hernia)
- Above the bellybutton
What are the symptoms of abdominal wall hernias?
Abdominal wall hernias do not always cause symptoms. When they do, they can cause some or all these symptoms:
- A bulge somewhere on the trunk of the body
- Pain, especially when coughing, straining, or using nearby muscles
- A pulling sensation around the bulge
Abdominal wall hernias can balloon out and form a sac. That sac can end up holding a loop of intestine or a piece of fat that should normally be tucked inside the belly. This can be painful and even dangerous if the tissue in the hernia gets trapped and unable to slide back into the belly.
Should I see a doctor?
You should see a doctor if you have a hernia which is causing you any of the symptoms listed above. In most cases, doctors can diagnose a hernia just by doing an exam. During the exam, the doctor might ask you to cough or bear down while pressing on your hernia. This might be uncomfortable, but it is necessary to find the source of the problem.
If you develop pain around a hernia bulge or feel sick, call your doctor or surgeon right away.
How are abdominal wall hernias treated?
Not all hernias need treatment right away. But many do need to be repaired with surgery. Surgeons can repair most hernias in 1 of 2 ways. The right surgery for you will depend on your size, the size of your hernia, where on the abdominal wall it is, whether this is the first time it is getting repaired. The types of surgery are:
- Open Surgery – During an open surgery, the surgeon makes an incision near the hernia (the size of the incision depends on the size of the hernia and the patient). The tissue that is stuck in the hernia is replaced or removed, and the hernia defect is closed with sutures. If the hernia is large the repair is reinforced with a mesh.
- Laparoscopic Surgery – During laparoscopic surgery, three small incisions that are smaller than those used in open surgery, are placed on the flank. A camera (called a “laparoscope”) is used to visualise the hernia and allow repair. The surgeon can look at the picture on the screen to guide his or her movements. The hernia is reduced into the abdomen and then repaired using specially designed mesh.
- Emergency Hernia Surgery – If the bowel or other abdominal contents are caught in the hernia emergency hernia surgery may be required. If the bowel is blocked or has lost its blood supply, removal of that portion may be required.
