title: Intestinal motility disorders of infants and children: classification, clinical manifestations and roentgenology.
abstract: Diseases affecting intestinal motility in the pediatric age group are reviewed as to pathophysiology, clinical manifestations, and imaging investigation. Acute disease includes classical paralytic ileus (which has unique causes and manifestations in the infant) and acute regional bowel paralysis. Perinatal motility disorders consist of a group of related clinical syndromes which have in common functional intestinal obstruction. Chronic motility disorders are divided into those diseases in which the principal abnormality is in the bowel or those entities where the gut is affected as part of a generalized disease. Regional muscle disease includes Hirschsprung's disease and allied disorders. Some recognized causes of chronic functional obstruction of bowel include megacystis-microcolon-intestinal hypoperistalsis syndrome, rare enzymatic disorders, several discrete forms of chronic intestinal pseudoobstruction, as well as some less well-defined entities. Clinical and pathologic nature and methods of imaging investigation of these entities are considered.
