Gluteal myoplasty for sphincter replacement: principles, results and prospects

The treatment of anal incontinence following anorectal malformations and their treatment can be done even if the colic pull-down has been carried out of the levatori ani muscle sling. The use of the gluteus maximus encircling the neorectum with a contractile muscular ring provides an active control of continence, and reverses the anorectal angulation. The rationale of the myoplasty has been pointed out and our first resulted analyzed. The use of voluntary contraction limits the scope of an operation whose effects can be lost during sleep. But the voluntary daytime control makes it possible for the patient to take part in school, occupational or sportive activities.
