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.
The word 'prevalence' of Intussusception usually means the estimated population of people who are managing Intussusception at any given time (i.e. people with Intussusception). The term 'incidence' of Intussusception means the annual diagnosis rate, or the number of new cases of Intussusception diagnosed each year (i.e. getting Intussusception). Hence, these two statistics types can differ: a short disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence Incidence (annual) of Intussusception: about 2 per 1000 cases in infants Incidence Rate for Intussusception: approx 1 in 500 or 0.20% or 544,000 people in USA
An enema is the first step in treatment. In fact, an enema that is used to diagnose intussusception may also help to treat it. Pressure from the air or fluid may cause the intestine to correct itself. The result of an enema treatment might not last, so patients usually stay in the hospital overnight for observation. Surgery is another treatment option. Intussusception surgery involves either a large incision or a small incision and a camera. This is called laparoscopic surgery. The type of surgery depends on the location and severity of the obstruction. Intussusception surgery may include removal of the affected section of intestine.
