Approche chirurgicale de l'incontinence anale de l'adulte

Surgical treatment of anal incontinence is indicated only for patients who have failed medical treatment. Sphincterorraphy is suitable in case of external sphincter rupture. In the last decade, sacral nerve stimulation has proven to be a scientifically validated solution when no sphincter lesion has been identified and more recently has also been proposed as an alternative in cases of limited sphincter defect. Anal reconstruction using artificial sphincters is still under evaluation while indications for dynamic graciloplasty are decreasing due to its complexity and high morbidity. Less risky techniques involving intrasphincteric injections are being developed, with encouraging preliminary results that need to be confirmed especially in the medium and long-term. Antegrade colonic enemas instilled via cecostomy (Malone) can be an alternative to permanent stoma in patients who are well instructed in the techniques of colonic lavage. Stomal diversion is a solution of last resort.
