The basic pathophysiologic disturbance in Hirschsprung's disease is a functional obstruction caused by defective intramural nerve supply and by internal anal sphincter achalasia. Therapy consists in resecting the dysganglionic bowel segment. In each case however an aganglionic segment of different length and an internal analsphincter with a different degree of achalasia remain in situ. Therefore the postoperative results are dependant on an equilibrium between the proximal normal innervated colon and the length and function of the remaining aganglionic and achalic parts of the rectum and anal canal. In about one third of all patients with Hirschsprung's disease disturbances of this equilibrium postoperatively lead to enterocolitis, encopresis, or chronic constipation. Five years later however the authors could observe enterocolitis in only 7.3% chronic constipation in 9.5% and encopresis in 13.9% of their operated patients. With increasing time after operation there is a growing tendency towards the spontaneous regeneration. Therefore, the prognosis of Hirschsprung's disease is very good: about 90% of all cases can be cured.

D006627 Hirschsprung Disease Congenital MEGACOLON resulting from the absence of ganglion cells (aganglionosis) in a distal segment of the LARGE INTESTINE. The aganglionic segment is permanently contracted thus causing dilatation proximal to it. In most cases, the aganglionic segment is within the RECTUM and SIGMOID COLON.
