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.
