Rectal neovagina: Simonsen's technique for large rectovaginal fistula repair.

Rectovaginal fistulas are difficult to manage and cause significant morbidity. A new technique for large rectovaginal fistula repair is presented; it is based on the creation of a neovagina associated with an established abdominal pull-through operation. This technique has been used since 1970 in selected cases, with very little morbidity and no operative mortality.
