Six patients incapacitating faecal incontinence, in whom conventional treatment had either failed or was contraindicated, were treated by a new technique. A neonanal sphincter was constructed by transposing the gracilis muscle around the anal canal. Chronic neuromuscular stimulation via an implanted electrical stimulator was then used in an attempt to convert the muscle to a slow twitch fatigue resistant muscle. Physiological measurements suggested that this conversion had begun, enabling the neosphincter to mount a sustained contraction. Five patients had their covering stomas closed, and continence was improved in all of them. However, one patient could not cope psychologically with the stimulator, and another patient was continent for long periods only when the neosphincter was used in conjunction with a silastic plug. This new technique may benefit selected patients with incontinence whose only alternative would be a permanent stoma.
