[Prospective study of gracilis muscle repair of complex rectovaginal fistula and rectourethral fistula].
OBJECTIVE
To assess the efficacy and experience of gracilis muscle transposition for complex rectovaginal fistula (RVF) and rectourethral fistula (RUF).


METHODS
Nineteen patients underwent gracilis muscle transposition for complex RVF and RUF from May 2009 to November 2011 in the Beijing Shijitan Hospital and the clinical data were prospectively collected. The success rate and complications were recorded. SF-36 quality of life score, Wexner fecal incontinence score, and female sexual function score before surgery and 6 months after surgery were recorded.


RESULTS
In 19 patients, there were 8 males (RUF) and 11 females (RUF). The times of failed attempt repair preoperatively ranged from 0-3 (mean, 1.0). The diameter of the fistula ranged from 0.5-3.0 cm (mean, 1.6), and all fistulas located above the sphincter. The operative time ranged from 145-400 minutes (median, 240). The postoperative hospital stay ranged from 10-39 days (median 21). Early postoperative complications included thigh pain and numbness in 2 cases, leg numbness in 2 cases. No long-term complications were noticed. The follow-up period ranged from 6-35 months (median, 18). The gracilis muscle transposition had a healing rate of 94.7% (18/19). As compared with the preoperative level, Wexner score decreased from 10.0±8.8 to 2.9±5.8, and the continence function improved significantly (P=0.002). Sexual function score of 11 female patients increased from 1.0±1.8 to 4.0±4.0, and the sexual function had a significant improvement after surgery (P=0.022). SF-36 quality of life scores improved significantly (P<0.001).


CONCLUSIONS
Gracilis muscle transposition for complex rectovaginal fistula and rectourethral fistula has high success rate with mild and rare complications.
