Congenital H-Type Anorectal Fistula: Two Case Reports

The congenital H-type fistula between the anorectum and the urogenital tract without anal atresia is an extremely rare entity in the spectrum of anorectal anomalies. We report about two young girls, who had a congenital fistula between the left labium/vulva and the anus (= H-type fistula). After the management of the local infection and the abscess, the two patients underwent an anterior sagittal anorectovaginoplasty (ASARVP). Up to now there was no relapse of the fistula or the abscess in both cases. Thus ASARVP can be used as a simple method for congenital H-type fistulas with excellent functional and anatomical results.
