Complications

By Mayo Clinic staff

Intussusception can cut off the blood supply to the affected portion of the intestine. If left untreated, lack of blood causes tissue of the intestinal wall to die. Tissue death can result in a tear (perforation) in the intestinal wall, which can lead to peritonitis, an infection of the lining of the abdominal cavity.

Peritonitis is a life-threatening condition that requires immediate medical attention. Signs and symptoms of peritonitis include:

  • Abdominal pain
  • Abdominal swelling
  • Fever
  • Thirst
  • Low urine output

Peritonitis may cause your child to go into shock. Signs and symptoms of shock include:

  • Cool, clammy skin that may be pale or gray
  • A weak and rapid pulse
  • Abnormal breathing that may be either slow and shallow or very rapid
  • Dilated pupils in the eyes
  • Lackluster eyes that seem to stare

A child who is in shock may be conscious or unconscious. If you suspect your child is in shock, seek emergency medical care right away.
