A six-year-old girl with surgically corrected imperforate anus and chronic
faecal soiling was successfully treated by biofeedback. A portable biofeedback
machine using an anorectal balloon was constructed and lent to the patient’s
mother who administered the treatment at home following instruction in the
clinic. Faecal incontinence was replaced by normal bowel evacuation habits
after four weeks of the procedure. The effect was durable at least until
follow-up at three months. Positive spin-offs were observed. The reversal of
the child's encopresis suggested neuromuscular intactness of the anorectalregion despite the congenital malformation. Biofeedback probably compensated
for an earlier learning fault. Domiciliary, parent-mediated biofeedback
therapy is a cost-effective procedure and may be widely applicable to suitable
patients within the population of children with primary expulsive and retentive
bowel control disorders.
