Fecal incontinence: a simple pneumatic device for home biofeedback training.

A simple pneumatic biofeedback device has been designed for patients who have failed to develop social fecal continence following sacroabdominoperineal pull-through operations for anorectal anomalies. The components that make up the device are easily and cheaply available. This device was designed to be used by the patient at home and needs only the assistance of an adult.
