title: Rectovaginal fistulography: a technique for the identification of recurrent elusive fistulas.
abstract: OBJECTIVE
  The purpose of this study is to review our experience with a technique for diagnosing small rectovaginal fistulas that occasionally permit passage of air or mucus.
  
  
  METHODS
  During an in-office visit suspicious areas of the vagina were probed with a cone-tip catheter and injected with a contrast dye to visualize the suspected fistula tract communicating to the rectum under fluoroscopic guidance. The fistulous tracts were further isolated using a flexi-tip glide wire.
  
  
  RESULTS
  Five out of nine patients were found to have fistulas not diagnosed by other means. Three patients had recurrent rectovaginal fistula after a vaginal delivery, one patient was identified with a high rectovaginal fistula due to diverticular disease, and one patient had a rectovaginal fistula due to prior hemorrhoidectomy. One patient had a negative test, and the fistula that was diagnosed intraoperatively was due to underlying Crohn's disease.
  
  
  CONCLUSIONS
  Direct fistulography is a useful technique to visualize otherwise elusive symptomatic rectovaginal fistula tracts.
