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.
Centers for Disease Control and Prevention (CDC) report that in the world annually RV cause close to 111 million episodes of gastrointestinal infections treated at home, 25 million outpatient visits, 2 million hospitalizations (mainly due to the rapid course of diarrhea and dehydration) and from 352 thousand to 592 thousand deaths in children under 5 years old, wherein the deaths occur primarily in developing countries (440 thousand of deaths per year, while in the European Union about 230) . Children under 5 years of age are more likely to be infected (particularly between 6 months and 2 year of age). The heaviest course of acute diarrhea is observed in the neonatal and infancy period, where it is easy to disturb homeostasis due to the functional immaturity of the organism. RV infection is also one of the most common etiological factors of nosocomial infections. In Poland in 2009 20 689 cases of RV infections were registered in pediatric departments. Results of numerous studies show large-scale problem of RV infection in the pediatric population.
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.
