Creation of an anal sphincter mechanism by bilateral proximally based gluteal muscle transposition

A case report is given of a girl who, at the age of 17 years, lost her total posterior part of her perineum in a traffic accident. She was left with out an anal sphincter mechanism and a diverting sigmoidostomy was performed. Two years after the accident a new anal sphincter was constructed using bilateral transposition flaps of the gluteus maximus muscles. After 6 months of active training of this new "reanastomosed". The patient thereafter regained complete fecal continence by the natural route.
