Late presentation of a patient with an anorectal malformation (ARM)

Abstract

Vestibular fistula represents the most common type of anorectal defect seen in girls with anorectal malformation. Adult presentation of this malformation is rare. The following is a case of adult presentation of anorectal malformation with a vestibular fistula in a 23 years old female, who came because of cosmetic and fertility concerns before her marriage. The patient complained of having an anorectal malformation since birth and passage of fecal matter through the fistula. The patient was continent for feces, but had leakage of flatus. She had no other associated anomaly. The patient subsequently underwent a surgical procedure where anal transposition was done with an intact skin bridge. Post-operatively, these developed an anal stenosis which was successfully treated through anoplasty, and the patient is now continent both for feces and flatus for the last 6 months.
