BACKGROUND: Anorectal malformations (ARMs) affect 1 in 4000 to 5000 births. The Krickenbeck conference developed a classification based on anatomical and functional criteria to better compare treatment outcome. AIM: The aim of this study is to evaluate the functional outcome in patients 10 years following standardized surgical treatment of ARM related to the Krickenbeck classification. . METHODS: Anatomical anomalies were classified as above. Children and carers were followed closely in a multidisciplinary clinic. Data were collected using a functional outcome questionnaire for a minimum of 10 years after surgical reconstruction. Outcome measurements were related to the Krickenbeck classification. RESULTS: There were 53 children in the study group (29 male, 24 female). Krickenbeck anatomy: perineal fistula, 36%; vestibular fistula, 26%; rectourethral fistula, 36%; rectovesical fistula, 2%. All children were treated by posterior sagittal anorectoplasty. In children with perineal fistula, continence was achieved in 90%. Grade 2 constipation was noted in 21%. One child had a Malone antegrade continence enema (MACE) procedure. In children with vestibular fistula, continence was achieved in 57%. Grade 3 constipation was noted in 28%. One child had grade 1, and one child had grade 2 soiling. Two children had a MACE procedure. In children with rectourethral fistula, continence was achieved in 58%. One child had grade 3 soiling. Grade 3 constipation was found in 42% of children and grade 2 constipation in 1 child. A MACE procedure was performed in 36%. The only child with a bladder neck fistula had a MACE procedure for intractable soiling. CONCLUSIONS: The outcome for patients with ARM is related to the severity of the anomaly. The uniform application of the Krickenbeck classification should allow rational comparison of treatment outcome.
