[Biofeedback training and functional electrostimulation for improving incontinence in children with anal atresia].

Eleven children with anal incontinence following a pull-through operation for anorectal agenesis (4 low, 7 high anomalies) were treated with a conservative continence training program (optic/acoustic biofeedback, transcutaneous electrical stimulation, physical therapy, contraction exercises and sensibility training). All patients with one exception showed subjective and objective improvement of continence. Sphincter contraction increased by 80% in high and by 40% in low anomalies. For a short time electrostimulation provided an improvement of up to 20% in sphincter pressure. One additional success was improved coordination. Beside surgical therapy and other methods continence training is always indicated.
