Anal endosonography and electromyography in the evaluation of anorectal functions after correction of anorectal malformations

ABSTRACT

The anorectal function was assessed in 22 patients with corrected anorectal malformation [ARM] using anal endosonography [ES] and electromyography [EMC], 14 cases had high ARM and eight cases had intermediate ARM with ages ranged between 4-16 years. The anal ES findings of the external anal sphincter [EAS] and the internal anal sphincter [IAS] were compared with those of the EMG of [EAS] and were further correlated with the clinical assessment of continence based on Kelly score. The results of the anal ES corresponded significantly with the results of the EMG and the continence scoring system of Kelly where 10 cases were clinically continent, nine cases had clinical staining and three cases had soiling
