Management of faecal incontinence and results of surgical treatment

Ninety-five patients have been referred for the assessment and treatment of faecal incontinence. Incontinence was associated with previous anal trauma in 49 cases: 13 occurred after vaginal delivery, 32 were associated with anal operations and in 4 severe perineal trauma occurred after road accidents. Other causes were: idiopathic incontinence in 18, persistent incontinence despite successful rectopexy for prolapse in 10, diabetic neuropathy in 5 and in 13 the cause was not identified. Conservative treatment by control of diarrhoea, physiotherapy or electrical therapy was often successful in patients with minor incontinence. Fifty-six patients have been treated surgically. Complete continence was achieved in 67 per cent of patients treated by postanal repair and in 61 per cent by sphincter reconstruction. We believe that postanal repair is the treatment of choice for idiopathic incontinence and incontinence after rectopexy or anal dilatation. Sphincter repair should only be performed with a covering colostomy and is the treatment of choice for recent or long standing division of the external sphincter ring.
