RESUMO
BACKGROUND: Rectovaginal fistula, although infrequent, produces considerable discomfort to the patients and disables them in their social life. OBJECTIVES: To review and report the experience in the management of rectovaginal fistula in the Colon and Rectal Unit of the General Hospital of Mexico City, from January 1997 to December 2001. MATERIAL AND METHODS: A retrospective, observational and descriptive study was designed including all patients diagnosed with rectovaginal fistula, who had not been previously operated for this condition in the Colon and Rectal Unit of the General Hospital of Mexico City from January 1977 to December 2001. RESULTS: Thirty-eight patients were included, aged between 17 and 70 years with a mean age of 24. The etiology of the rectovaginal fistulas was: obstetric trauma in 21 patients (55.2%), post-surgical in 5 (13.1%), traumatic in 5 (13.1%), after radiotherapy in 5 (13.1%) and malignant in 2 (5.2%). DISCUSSION: Rectovaginal fistula treatment relies on fistula classification (simple or complex), its location, and damage or not to the sphincter mechanisms and prior surgical repair. CONCLUSIONS: The most frequent surgical approach was the creation of a fourth degree perineum laceration and reconstruction (45.7%), followed by the advancement flap (25.7%). Complex fistulas were handled with a stoma. The surgical approach of rectovaginal fistula must rely on etiologic, anatomic and physiologic basis.
