Intussusception occurs when one segment of bowel is pulled into itself (or a neighboring loop of bowel) by peristalsis.
It is an important cause of an acute abdomen in children and merits timely ultrasound examination and reduction to preclude significant sequelae including bowel necrosis.
Intussusception may also occur in the adult population where it is usually caused by a focal lesion acting as a lead point.
