Overview

Hirschsprung's disease is a blockage of the large intestine due to improper muscle movement in the bowel. It is a congenital condition, which means it is present from birth.

What are the symptoms of Hirschsprung's disease?

What are the causes of Hirschsprung's disease?

Muscle contractions in the gut help digested materials move through the intestine. This is called peristalsis. Nerves in between the muscle layers trigger the contractions.

In Hirschsprung's disease, the nerves are missing from a short or long part of the bowel. Areas without such nerves can not push material through. This causes a blockage. Intestinal contents build up behind the blockage, causing the bowel and abdomen to become swollen. If the condition is severe, the newborn may fail to pass meconium or stool, and the newborn may vomit.

Milder cases may not be diagnosed until a later age. In older children, the disease may be cause chronic constipation, abdominal swelling, and decreased growth.

Hirschsprung's disease causes about 25% of all newborn intestinal obstruction. It occurs five times more frequently in males than in females. Hirschsprung's disease is sometimes associated with other inherited or congenital conditions such as Down syndrome.

Who is at risk for Hirschsprung's disease?

Risk Factors include:

  • Gender - males have a higher risk than females
  • Having a congenital condition such as Down Syndrome

Diagnosis

During a physical examination, the doctor may be able to feel loops of bowel in the swollen belly. A rectal examination may reveal a loss of muscle tone in the rectal muscles.

  • Tests used to help diagnose Hirschsprung's disease may include:
    • Abdominal x-ray
    • Anal manometry (a balloon is inflated in the rectum to measure pressure in the area)
    • Barium enema
    • Rectal biopsy

When to seek urgent medical care?

Call your child's health care provider if symptoms of Hirschsprung's disease develop.

Call your child's health care provider if your child has abdominal pain or other new symptoms after being treated for this condition.

Treatment options

The abnormal section of colon must be surgically removed. Sometimes this can be done in one operation. However, it is frequently done in two parts with a colostomy being performed first, and another procedure being performed later in the first year of life.

What to expect (Outlook/Prognosis)?

Symptoms improve or are eliminated in most children after surgical treatment. A better outcome is associated with early treatment and shorter bowel segment involvement.
