[Preliminary Results of Transperineal Ligation of Fistula Tract for Rectovaginal Fistulas].

BACKGROUND

Despite a variety of surgical procedures for rectovaginal fistulas, surgical therapy remains a considerable challenge. Therefore, it was the aim of this prospective study to evaluate preliminary results of an innovative technique.

METHODS

Surgical transperineal ligation of the fistula tract was performed without any fistulectomy or sphincter reconstruction. Only lower rectovaginal fistulas were selected for this technique. Standardised inclusion and exclusion criteria were defined.

RESULTS

Within a 16-month period, 7 female patients with lower rectovaginal fistulas were treated by transperineal ligation of the fistula tract in two centres. Rectovaginal fistulas were associated with iatrogenic obstetric trauma, following Bartholin infection, and with Crohn's disease. In all cases, rectovaginal fistulas could be identified and treated by ligation of the fistula tract. Neither intra- nor postoperative complications were documented. Only one operation was performed under fecal diversion. After a mean follow-up of 9 months, fistula healing was observed in 4 of 7 patients (success rate 57%).

CONCLUSION

Preliminary results of transperineal ligation of the fistula tract for rectovaginal fistulas seem to be promising. However, further experience, larger series and long-term follow-up have to be provided to objectively assess this innovative technique.
