Abstract
A group of 176 patients aged 2-15 yr was investigated for idiopathic disorders of bowel function other than Hirschsprung''s disease. Anorectal motility, as well as colorectal transit of radiopaque markers, were investigated. Before the end of the 1st mo. of life, 70 of the patients were constipated. Resting pressure was more unstable (P < 0.001) and higher than normal in the rectal ampulla and upper anal canal (P < 0.01). Retardation of markers occurred in the proximal and/or distal large bowel of 61% of the patients. The existence of functional abnormalities was demonstrated in the majority of children with idiopathic disorders of fecal continence.
