Complete vaginal prolapse: an unusual presentation of anovestibular fistula.
An adolescent girl with an anovestibular fistula presenting as a complete vaginal prolapse and large-bowel obstruction is reported. The prolapse was reduced manually after repeated bowel washouts and a divided high sigmoid colostomy. The patient is awaiting posterior sagittal anorectoplasty. Possible etiopathologic factors of the prolapse are discussed. A vaginal prolapse in a patient with an anorectal malformation has not been reported previously in the English literature.
