Diagnosis

Your or your child's doctor will start by getting a history of the symptoms of the problem. He or she may be able to feel a sausage-shaped lump in the abdomen. To confirm the diagnosis, your doctor may order:

  • Ultrasound or other abdominal imaging. An ultrasound, X-ray or computerized tomography (CT) scan may reveal intestinal obstruction caused by intussusception. Imaging will typically show a "bull's-eye," representing the intestine coiled within the intestine. Abdominal imaging also can show if the intestine has been torn (perforated).
  • Air or barium enema. An air or barium enema is basically enhanced imaging of the colon. During the procedure, the doctor will insert air or liquid barium into the colon through the rectum.

    In addition, an air or barium enema can actually fix intussusception 90 percent of the time in children, and no further treatment is needed. A barium enema can't be used if the intestine is torn.
