What is Intussusception?
Intussusception is the sliding of one part of the intestine into another.
What are the symptoms of Intussusception?
The first sign of intussusception is usually sudden, loud crying caused by abdominal pain. The pain is colicky and not continuous (intermittent), but it comes back often, increasing in both intensity and duration.
An infant with severe abdominal pain may draw the knees to the chest while crying.
Other symptoms include:
- Bloody, mucus-like bowel movement, sometimes called a "currant jelly" stool
- Fever
- Shock (pale color, lethargy, sweating)
- Stool mixed with blood and mucus
- Vomiting
What are the causes of Intussusception?
Intussusception is caused by part of the intestine being pulled inward into itself. This can block the passage of food through the intestine. If the blood supply is cut off, the segment of intestine pulled inside can die.
The pressure created by the walls of the intestine pressing together causes:
- Decreased blood flow
- Irritation
- Swelling
The intestine can die, and the patient can have significant bleeding. If a hole occurs, infection, shock, and dehydration can take place very rapidly.
The cause of intussusception is not known, although viral infections may be responsible in some cases. Sometimes a lymph node, polyp, or tumor can trigger the problem. The older the child, the more likely such a trigger will be found.
Who is at risk for Intussusception?
Risk Factors:
- Age: Intussusception can affect both children and adults, although most cases occur in children ages 6 months - 2 years
- Gender: It affects boys four times as often as girls
How to know you have Intussusception (Diagnosis)?
Your doctor will perform a thorough examination, which may reveal a mass in the abdomen. There may also be signs of dehydration or shock.
Tests may include:
- Abdominal x-ray
- Air or contrast enema
