Gracilis muscle transposition for fistulas between the rectum and urethra or vagina.
OBJECTIVE
This study was designed to assess the efficacy of gracilis muscle transposition in repairing rectovaginal and rectourethral fistulas.


METHODS
Data were retrieved from a retrospective chart review of patients who underwent gracilis muscle transposition for fistulas between the rectum and urethra/vagina. All patients had fecal diversion as a preliminary or concurrent step to fistula repair. Follow-up data were gathered from outpatient clinic visits. Success was defined as a healed fistula after stoma closure.


RESULTS
Six females and three males, aged 30 to 64 years, underwent gracilis muscle transpositions from 1999 to 2005. One pouch-vaginal, three rectourethral, and five rectovaginal fistulas were repaired. The etiologies were Crohn's disease (n = 2), iatrogenic injury to the rectum during radical prostatectomy (n = 2), previous pelvic irradiation for rectal cancer (n = 2) or for cervical cancer (n = 1), recurrent perianal abscesses with fistulas (n = 1), and obstetric tear (n = 1). Seven patients underwent previous medical and surgical repair attempts. There were no intraoperative complications. Postoperative complications included perineal wound infection (n = 1) and at the colostomy closure (n = 2). There were no long-term sequelae. At a median follow-up period of 14 (range, 1-66) months since stoma closure, the fistula healed in seven patients. One patient refused ileostomy closure. One patient with severe Crohn's proctitis has a persistent rectovaginal fistula.


CONCLUSIONS
Gracilis muscle transposition is a viable option for repairing fistulas between the urethra, vagina, and the rectum, especially after failed perineal or transanal repairs. It is associated with low morbidity and a good success rate. Underlying Crohn's disease and previous radiation are associated with poor prognosis.
