[Prospective study of the transit time in intestinal neuronal abnormalities].

In a prospective study 106 children with intestinal neuronal malformations underwent intestinal transit-time studies. In only 50% of the children with intestinal neuronal dysplasia type B or immature ganglia was the transit time prolonged. On the contrary, hypoganglionosis and heterotopia of the submucous plexus led to severe transport disorders with subsequent bowel resection.
