Abstract
In a study of esophageal and gastric abnormalities in six children with dysautonomia, absent or decreased lower esophageal peristalsis was noted in all. A dilated atonic esophagus was noted in those with more severely decreased peristalsis, and emptying occurred only in the erect position in those with marked impairment. Varied degrees of pylorospasm and impaired gastric motility were present. Motility in the small intestine appeared to be normal. Difficulty in swallowing was especially marked in two patients. The radiologic demonstration of absent or decreased lower esophageal peristalsis may be of value as a diagnostic aid in dysautonomia.
