Excision of an Anovestibular Fistula with a Normal Anus Using a Biopsy Punch

Abstract

Among anorectal malformations (ARM), the isolated H type anovestibular fistula (AVF) with a normal anus is a rarity, affecting only approximately 3% of patients with anorectal malformations. AVFs are abnormal, epithelial-lined connections between the anal canal and vestibulum, and their management is a challenge for surgeons. Complete excision of the entire fistula tract is the goal of treatment, but this can often be difficult. Moreover, recurrences are not so rare. Fistulas can occur as a result of a congenital malformation, but most often have an acquired etiology. Here, we report AVF with a normal anus in a newborn. The fistula repair was performed using a biopsy punch and layered closure without overlapping suture lines, when the patient was 4 months old.
