Preservation of the Fistula for Reconstruction of the Anal Canal and the Anus in Atresia Ani and Rectovestibular Fistula in 2 Dogs

Abstract

Preservation of the fistula may provide an internal sphincter that contributes to a better functional result during correction of atresia ani. A surgical approach that combines episiotomy and perineal incision for separation of the vagina and rectum, and preserves the fistula may decrease the risk of dehiscence.
