Lessons to be learned: a case study approach. Chronic intussusception in childhood.

Chronic intussusception as a cause of persistent abdominal pain in children is often an overlooked diagnosis. Here we present an eight-year-old boy, who at the age of three years had an acute intussusception reduced hydrostatically with barium and who subsequently had been extensively investigated both in Wales and in Switzerland, for persistent colicky abdominal pain. He was found to have chronic intussusception, with a Meckel's diverticulum being the cause of his symptoms.
