Anterior sagittal anorectoplasty for rectovestibular and anovestibular fistula

Abstract

Rectovestibular (or anovestibular) fistula is the most common form of anorectal anomaly in female infants. In the surgical repair of these malformations, anal transplantation has been in widespread conventional use. Based on the idea of posterior sagittal anorectoplasty, we devised a new approach, anterior sagittal anorectoplasty, in which, in the lithotomy position, the anterior portion of sphincter muscles are cut through a median perineal skin incision and then the rectum is pulled through the center of these muscles to make its opening at the normal position. The operation has been performed in 12 patients with satisfactory results.
