Anus perinei ventralis in adulthood - case report.

Anorectal malformations present a type of the most serious congenital malformations, either in terms of treatment or treatment outcomes. Anorectal atresia can be subdivided into three categories: the supralevator form, the intermediate type of atresia and the low translevator type. One of the clinical forms of low translevator type in girls is a perineal fistula opening just behind the vaginal entrance on the perineum, with a fully developed sphincter complex dorsally from the fistula (so called anus perinei ventralis). The golden standard of surgical treatment of anus perinei ventralis in children is Peñas procedure, which was used as a guideline for anorectal reconstruction in our adult patient, as well.
