Objective: To describe a case of perineal ectopic anus (cutaneous fistula) in the adult and its surgical treatment.
Design: Case description.
Setting: Third level health care hospital.
Case description: Female patient, 48 eight years old, with anorectal malformation and a history of total anal incontinence since childhood, coursing the last eight months with recurrent vaginal infections refractory to treatment. We found lack of perineal body, rectal opening (fistula) behind the vaginal fourchette, flat anal pit posterior to the fistula and inadequate muscular contraction to cutaneous perineal stimulation. Lack of tone and contraction of the anal sphincter. Studies consisted of endoanal ultrasound, MRI of the pelvic floor, neurophysiological assessments (electromyography of the anal sphincter, motor latency of pudendum nerves), and proctogram. Anorectal malformation, classified as Perineal Ectopic Anus (cutaneous fistula) was diagnosed. Treatment consisted in surgical correction of the congenital anomaly through an anorectoplasty (rectal reimplantation), achieving anatomical correction of the defect and anal continence.
Conclusions: Anorectal malformations in the adult are rare. This case reports reveals the possibility of finding anorectal anomalies in adult women as the cause of anal incontinence and recurrent vaginal infections. It is necessary to choose the adequate surgical treatment.
