What is intussusception?

Intussusception is the most common cause of intestinal obstruction in children between ages 3 months and 3 years old. Intussusception occurs when a portion of the intestine folds like a telescope, with one segment slipping inside another segment. It can occur in the colon, the small bowel, or between the small bowel and colon. The result can be a blocked small bowel or colon. This causes an obstruction, preventing the passage of food that is being digested through the intestine.

The walls of the 2 "telescoped" sections of intestine press on each other, causing irritation and swelling. Eventually, the blood supply to that area is cut off, which can cause damage to the intestine.

What causes intussusception?

The cause of intussusception is not known. It may occur more frequently in people who have relatives who also had intussusception.

Though rare, an increased incidence of developing intussusception may be seen in children:

  • Who have abdominal or intestinal tumors or masses

  • Who have appendicitis

How often does intussusception occur?

Intussusception is rarely seen in newborn infants. Although most of the children who develop the condition are less than 3 years old, intussusception can also occur in older children, teenagers, and adults.

  • Intussusception occurs more often in boys than girls.

Why is intussusception of concern?

Intussusception is a life-threatening illness. If left untreated, it can cause serious damage to the intestines, since their blood supply is cut off. Intestinal infection can occur, and the intestinal tissue can also die. Untreated intussusception can also cause internal bleeding and a severe abdominal infection called peritonitis.

What are the symptoms of intussusception?

The most common symptom of intussusception is sudden, loud crying caused by an onset of intermittent abdominal pain in a previously well child. However, each child may experience symptoms differently. The pain may be mistaken for colic at first, and occurs at frequent intervals. Infants and children may strain, draw their knees up, act very irritable, and cry loudly. Your child may recover and become playful in-between bouts of pain, or may become tired and weak from crying.

Vomiting may also occur with intussusception, and it usually starts soon after the pain begins.

Your child may pass a normal stool, but the next stool may look bloody. Further, a red mucus or jelly-like stool is usually seen with intussusception.

Symptoms of intussusception, such as fever, lethargy, vomiting bile, diarrhea, sweating, dehydration, and an abdominal distention or lump, may resemble other conditions or medical problems. Please consult your child's doctor for a diagnosis.

How is intussusception diagnosed?

A doctor will obtain a medical history and perform a physical examination of your child. Imaging studies are also done to examine the abdominal organs, and may include:

  • Abdominal X-ray. A diagnostic test that may show intestinal obstruction.

  • Ultrasound. A diagnostic imaging technique that uses high frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view organs as they function and to assess blood flow through various vessels.  

  • Upper GI (gastrointestinal) series. A diagnostic test that examines the organs of the upper part of the digestive system: the esophagus, stomach, and duodenum (the first section of the small intestine). A fluid called barium (a metallic, chemical, chalky liquid used to coat the inside of organs so that they will show up on an X-ray) is swallowed. X-rays are then taken to evaluate the digestive organs.

  • Barium enema (also called a lower GI series). A procedure performed to examine the large intestine for abnormalities. A fluid called barium (a metallic, chemical, chalky, liquid used to coat the inside of organs so that they will show up on an X-ray) is given into the rectum as an enema. An x-ray of the abdomen shows strictures (narrowed areas), obstructions (blockages), and other problems. On some occasions, the pressure exerted on the intestine while inserting barium will help the intestine to unfold, correcting the intussusception.

What is the treatment for intussusception?

Specific treatment for intussusception will be determined by your child's doctor based on the following:

  • The extent of the problem

  • The health of the child

  • The opinion of the health care providers involved in the child's care

  • Your opinion and preference

In some instances, intussusception will fix itself while being diagnosed with a barium enema. Or, in many cases, the doctor can correct the problem by giving an air enema. This is done by placing a small tube in your child's rectum and inserting air through the tube. The air may help move the intestine back into its normal position. However, if your child is very ill with an abdominal infection or other complications, your doctor may not choose to perform this procedure.

Treatment may include:

What is the long-term outlook for a child with intussusception?

If not treated, intussusception is a life-threatening disorder. If treated within 24 hours, most babies recover completely.

The long-term outlook depends on the extent of intestinal damage (if any). Children with intestinal injury who had the damaged part removed may have long-term problems. When a large portion of the intestine is removed, the digestive process can be affected.

Consult your doctor regarding the prognosis for your child.
