Thirty-three adolescents (aged 12 to 20 years; median, 15) with a corrected low (n = 17) or high (n = 16) anorectal anomaly were assessed using anorectal physiological examination, semistructured interviews [Child Assessment Schedule [CAS]), and questionnaires (Child Behavior Checklist [CBCL], Youth Self-Report [YSR]). Seven patients, all of whom had low malformations, were totally continent. Twenty-three (70%) had persistent dysfunction with staining (n = 12) or intermittent/constant soiling (n = 11). Twenty-four (73%) had flatus incontinence. Fecal incontinence correlated negatively with anal canal resting pressure (r = - .58, P = <.001) and squeeze pressure (r = -.54, P < .01). Three adolescents had a permanent colostomy. Nineteen patients (58%) met the criteria for a psychiatric diagnosis, and impairment of psychosocial function was found in 24 (73%). The degree of psychosocial impairment correlated significantly with fecal incontinence (F = -.37, P < .05) and flatus incontinence (r = -.49, P < .01). Continence of flatus correlated significantly with mental health symptom scores (YSR: r = .52, P < .01; CAS:r = .53, P < .01). The findings indicated that, in addition to soiling, staining as well as fear of flatus are associated with psychiatric and psychosocial dysfunction among patients with anorectal malformations. Optimal treatment of patients with low and high anorectal anomalies requires somatic and psychological care and follow-up into adulthood.
