A Case of Megacolon
نویسنده
چکیده
Megacolon is a relatively rare condition appearing in childhood and characterised by obstinate constipation, dilatation of the colon and hypomotility of its wall. It was Yon Ammon who first described megacolon in 1842, fortyfive years before Hirschsprung, though the disease carries the name of the latter. Since then many {etiological factors have been considered, ranging from malnutrition to neurological disorder but for the last decade or so it is the neurogenic theory which has come to the forefront and now there remains little doubt that Hirschsprung's disease is due to dysfunction of the autonomic nervous system.
