Hirschsprung's disease

Hirschsprung's disease (HD) is a disorder of the abdomen that occurs when part or all of the large intestine or antecedent parts of the gastrointestinal tract have no nerves and therefore cannot function. During normal fetal development, cells from the neural crest migrate into the large intestine (colon) to form the networks of nerves called Auerbach's plexus and Meissner's plexus.

In Hirschsprung's disease, the migration is not complete and part of the colon lacks these nerve bodies that regulate the activity of the colon. The affected segment of the colon cannot relax and pass stool through the colon, creating an obstruction.
