Intussusception

Abstract

Intussusception is a common cause of small bowel obstruction in infants and children. It is usually seen in children between 6 and 10 months of age, with idiopathic ileocolic intussusception being the most common type. In older children, pathologic lead points as the cause of intussusception are more common. Diagnosis is made by abdominal ultrasound. Air or contrast enema is the standard initial treatment option for intussusception and in high-volume centers has a high success rate and favorable safety profile. It may be repeated multiple times prior to resorting to operative reduction. Laparoscopy has gained favor as the initial operative strategy for reduction if repeated enemas fail. Laparotomy remains an option for cases in which laparoscopy is unsuccessful.
