Information for Patients


Also called: Enterocele

A hernia happens when part of an internal organ or tissue bulges through a weak area of muscle. Most hernias are in the abdomen.

There are several types of hernias, including

  • Inguinal, in the groin. This is the the most common type.
  • Umbilical, around the belly button
  • Incisional, through a scar
  • Hiatal, a small opening in the diaphragm that allows the upper part of the stomach to move up into the chest.
  • Congenital diaphragmatic, a birth defect that needs surgery

Hernias are common. They can affect men, women, and children. A combination of muscle weakness and straining, such as with heavy lifting, might contribute. Some people are born with weak abdominal muscles and may be more likely to get a hernia.

Treatment is usually surgery to repair the opening in the muscle wall. Untreated hernias can cause pain and health problems.

Intestinal Obstruction

Also called: Bowel obstruction, Intestinal volvulus, Paralytic ileus

An intestinal obstruction occurs when food or stool cannot move through the intestines. The obstruction can be complete or partial. There are many causes. The most common are adhesions, hernias, cancers, and certain medicines.

Symptoms include

  • Severe abdominal pain or cramping
  • Vomiting
  • Bloating
  • Loud bowel sounds
  • Swelling of the abdomen
  • Inability to pass gas
  • Constipation

A complete intestinal obstruction is a medical emergency. It often requires surgery.
