[Invagination in children. New diagnostic and therapeutic aspects].

Based on the literature and our own experience, we recommend ultrasound examination as a routine in infants and small children with acute abdominal pain. If a pseudotumour is diagnosed, with suspicion of an intussusception, we verify the diagnosis by an air enema, and also use this for treatment under the surveillance of fluoroscopy and a conventional blood pressure manometer. The results are encouraging.
