[Functional colon sonography in neuronal intestinal dysplasia. Report of 3 cases].

For the first time morphology and function of the colon were analysed by sonography in three children with M. Hirschsprung and neuronal-intestinal dysplasia. After one year two children attained almost normalisation of colon-peristalsis in the nonaganglionic segments. A resection of the neuronal-dysplastic segments was not necessary. In one child there was seen no change of the distal colon motility. The limit of resection at operation was determined by sonographic diagnosis following observation of stimulated motility. Sonographic long-time examination in connection with medicamental stimulation of the colon allows determination on timing and kind of therapy in neuronal-intestinal dysplasia.
