The clinical application of anorectal manometry was pioneered by pediatric surgeons. Swenson in 1949 reported that the aganglionic bowel of patients with Hirschsprung’s disease did not show any propulsive movements. In 1967 Lawson and Nixon and Schnaufer et al. found that the rectosphincteric reflex, which is observed in both normal individuals and patients with chronic idiopathic constipation, is absent in patients with Hirschsprung’s disease, and suggested anorectal manometry to be useful for the differentiation of Hirschsprung’s disease from chronic idiopathic constipation.
