Motility of the anorectum after "rectoplasty with posterior triangular colonic flap" in Hirschsprung's disease.

Clinical assessment of fecal continence and anorectal manometry were carried out in 22 patients with Hirschsprung's disease who had undergone "Rectoplasty with posterior triangular colonic flap". Satisfactory postoperative continence was achieved in 18 out of these 22 patients. The result of anorectal manometry disclosed that normal rectal compliance (reservoir function of the rectum), together with normal resting pressure of the anorectum and rectoanal reflex, is indispensable for an adequate postoperative continence.
