Biofeedback treatment of fecal incontinence in patients with myelomeningocele.
Approximately six hours of biofeedback training was given to eight fecally incontinent children with myelomeningocele in order to establish bowel control. Their ages ranged from five to 15 years. The patients were shown a polygraph tracing of the external anal sphincter while they were being encouraged voluntarily to contract the sphincter when the rectum was distended with progressively larger volumes of air in a balloon. Seven of the eight patients showed normal sensation for rectal distension. Following this training period, five of the children had no incontinent periods, and two of these had discontinued enemas or suppositories. A sixth patient had an 80 per cent reduction in the frequency of incontinence. The remaining two did not benefit. At follow-up between 13 and 24 months later, four children were incontinent once a month or less often; two others were incontinent once per day, a considerable decrease from the pretraining period. The two children who failed to learn were still incontinent at follow-up. These results show that fecally incontinent patients with myelomeningocele can learn to evacuate normally or to reduce soiling after a relatively short period of biofeedback training.
