Anorectal Malformation with Rectovestibular Fistula and Vaginal Agenesis: Usage of Rectovestibular Fistula as a Neovagina Followed by PSARP with Preservation of the Anal Sphincter.

Anorectal malformation with rectovestibular fistula associated with vaginal agenesis is rare. We report on a child in whom this combination was diagnosed at the age of 1 year. After creation of a divided descending colostomy, we chose to leave the rectum-rectovestibular fistula to function as a neovagina, while the sigmoid colon was relocated via modified posterior sagittal anorectoplasty.
