title: Anorectal motility in children with complete rectal prolapse.
abstract: Anorectal manometry, defecography, and ultrasonographic study were performed in 36 children with complete rectal prolapse and 45 age- and sex-matched controls. Anorectal manometry disclosed that there was no significant difference in Pr, Pac, or length of HPZ between patients and controls. The rate of BRC of the smooth muscle of the anal canal and RC were significantly lower in patients. Rectoanal reflex was present in all patients and controls. Defecography and ultrasonographic examination confirmed the hypothesis that rectal prolapse starts initially as an intussusception of the rectum, then fully develops. In 29 cases patients were cured by conservative treatment, but seven patients required surgical treatment. Results of modified Sudeck's operation were, in general, satisfactory.
