Defination Intussusception is a serious disorder in which part of the intestine slides into an adjacent part of the intestine. This "telescoping" often blocks food or fluid from passing through. Intussusception also cuts off the blood supply to the part of the intestine that's affected. Intussusception can lead to a tear in the bowel (perforation), infection and death of bowel tissue. Intussusception is the most common cause of intestinal obstruction in children younger than 3.
Symptoms Babies and children with intussusception have intense abdominal pain, which often begins suddenly and causes the child to draw the knees up toward the chest. The pain often makes the child cry very loudly. As it eases, the child may stop crying for a while and may seem to feel better. Symptoms also can include abdominal swelling, vomiting, lethargy, nausea, constipation, abdominal mass and stools with blood or mucus.
