[Sphincter-oriented gluteal myoplasty, in the treatment of faecal incontinence in sacral agenesis and surgically treated anorectal malformations (author's transl)].

The treatment of anal incontinence associated with anorectal malformations and sacral agenesis uses, in general, the levator ani. The role of the latter muscle can, however, only be passive, since it provides only suspension and angulation of the anorectal junction. Active control of continence may be obtained by means of an operation which encircles the rectum with a contractile muscular ring made up of the gluteus maximus muscles. It reverses the anorectal angulation and ensures effectice daytime continence by voluntary contraction. This control may be lost during sleep but it is felt that rehabilitation exercises can be successful. The technique is described here, detailing the advantages which may be hoped for and the present results.
