Fecal incontinence and obstipation are common problems in follow-up of anorectal malformations (ARMs). 17 patients, divided into 3 groups according to Wingspread Classification, underwent follow-up with anorectal manometry and questionnaires. Anal resting pressure was higher in low ARMs than in intermediate and high ARMs. No crucial difference was found in anal squeeze pressure between the 3 groups. A positive Rectoanal Inhibition Reflex (RAIR) was significantly more frequent in low ARMs than in high. Fecal incontinence was found in 60% oft the patients, especially in cases with negative RAIR and high ARMs. 40% of the patients were obstipated, but had voluntary defecation by adapted therapy. Different types of ARMs have a various outcome of fecal continence. Anorectal manometry enables objective evaluation and can show functional deficits in anal sphincter muscles.
