The Surgical Management of H-Type Rectovestibular Fistula: A Novel Modification

Abstract

Introduction H-type rectovestibular fistulas could be rare anorectal malformations or acquired diseases secondary to perianal infection. Various surgical procedures have been described in the literature, however the problem of recurrence still remains to be solved. We describe a novel modified surgical procedure and outcome in the management of these patients. Methods From 1999 to 2014, 14 patients who had an H-type rectovestibular fistula underwent the same surgical procedure performed by the same surgical team. Rectal-vestibular pull-through inside-out and endorectal mucosal advancement flap was used, including circumferential incision of the fistula from the opening on the rectal side, pulling the fistula inside-out, ligating the fistula, and mobilizing a rectal mucosal flap to cover the internal opening. Results All the patients have been followed-up for 12 months to 15 years with no recurrences and no incontinence. Conclusion Our surgical management is a simple, safe, and probable choice for the treatment of H-type rectovestibular fistula with favorable outcomes.
