Intussusception With Cecal Cyst as Lead Point in a Child.

Intussusception is a pediatric abdominal emergency in early childhood involving telescoping of 1 part of the bowel into another part. In most children, the condition is idiopathic with no identifiable lead point. Meckel diverticulum is the most common lead point, followed by polyps and duplication cysts. We describe a case of a boy with intussusception caused by a duplication cyst that was drawn retrograde through the ileocecal valve. The patient presented after a 3-month period of symptomatology and had been considered to have constipation before signs of intestinal obstruction developed. Only mild bowel ischemia was seen during the surgical reduction and resection of the cyst which may suggest an ongoing partial obstruction that eventually became more significant. In children with recurrent abdominal pain, surgeons should consider the possibility of intermittent intussusceptions caused by a duplication cyst.
