Hirschsprung's disease and congenital megacolon.

Hirschsprung's disease and congenital megacolon are recognized as separate entities. They differ one from another in clinical, roentgenographic and histologic features. Conservative treatment of patients with Hirschsprung's disease is ineffective; surgical therapy with a new technique is beneficial. In congenital megacolon, operation is futile and may be harmful, whereas patients may be benefited by conservative measures, and improvement may occur spontaneously after adolescence.
