[Segmental dilatation of the small intestine in a 10-year-old child].

Segmental dilatation of the small bowel is a rare disease. Formed during the first year of life, it could be due to a malformation or a subacute intestinal ischemia sometimes accompanying a deterioration of the myenteric plexus. The discovery of a dilated ileum in a 10 year old healthy child suggests that the anterior pathogenic hypothesis are invalid, especially because the anatomical study does not find any muscular or neurological deterioration.
