Abstract
The colonic tissue content of immunoreactive vasoactive intestinal peptide was measured in four children with histologically proven Hirschsprung's disease. The concentration of vasoactive intestinal peptide was lower in the aganglionic bowel than in nearby normal bowel. Similar results have been described for another gastrointestinal peptide: substance P. Abnormalities of peptidergic control may contribute to the motility disorder of congenital aganglionic colon.
