Traitement chirurgical de l’incontinence anale

Abstract

Surgery is mandatory for fecal incontinence when medical treatments and reeducation by biofeedback are ineffective. Sphincter disruption is the most frequent cause. Sphincter repair with or without overlapping is indicated in the large majority of cases. Short-term results are good but result is not ever mentained with time. In case of failure, or when the defect concerns more than 180°, it is necessary to use a substitutive technique. Artificial anal sphincter is often first proposed because of its apparent technical simplicity and because it is cheeper than dynamic graciloplasty. Results are excellent. Failures are due to local infection or devic edisfunction. Dynamic graciloplastie may be proposed in patients with severe perineal lesions, or failure of the other methods. Its results are also excellent, except for the patients having disordered rectal perception. Sacral nerve stimulation is limited to patients with idiopathic or neurologic incontinence. Because definitive implantation is done only following positive preoperative stimulation test, short-term results are very good.
