Use of an endorectal mucosal advancement flap to treat H-type rectovestibular fistula in patients with a normal anus.

Abstract: The combination of an H-type rectovestibular fistula (RVF) and a normal anus is a rare type of anorectal malformation, resulting in abnormal communication between the normal rectum and vestibule in girls. Among the surgical methods used to treat this condition are simple fistula resection and extensive perineal dissection, but postoperative fistula recurrence is frequent. We utilized the endorectal mucosal advancement flap technique on three patients with H-type RVFs and a normal anus, all of whom had favorable outcomes. [Copyright &y& Elsevier]
