Transvaginal repair of pouch-vaginal fistula

Abstract

Background: The results of surgery for ileoanal pouch-vaginal fistula have been disappointing. Intraanal procedures result in fistula healing in, at best, approximately 50 per cent of patients. A transvaginal approach was developed to achieve direct access to the internal opening, enabling closure without damage to the anal sphincter. Methods: Fourteen patients were treated between January 1992 and December 1998. All had had restorative proctocolectomy for ulcerative colitis and all were defunctioned. Histological review confirmed the diagnosis in all patients. Results: Median age was 40 (range 25-52) years. Median follow-up was 18 (range 6-60) months. The operation was successful in 11 of the 14 patients, after one attempt in six patients, after two attempts in four, and after three attempts in one patient. The operation failed in three patients, who had a permanent ileostomy. The number of bowel actions in the patients who had successful closure ranged from 2 to 10 (median 6) in 24h, with no faecal incontinence reported. Conclusion: This simple technique achieved healing in 11 of 14 patients. This compares favourably with the poor results in 28 patients treated by other procedures in the same hospital, with certain healing in five and definite failure in 20.
