Bricker-Johnston sigmoid colon graft for repair of postradiation rectovaginal fistula and stricture performed with mechanical sutures.

In patients with postradiation rectovaginal fistula who are otherwise healthy and cured of their cancer, repair of the fistula with return to a normal lifestyle is indicated if this repair can be achieved with minimal morbidity, no mortality, and a good prospect for a functionally satisfactory result. The Bricker-Johnston vascular sigmoid colon graft fulfills these conditions by respecting the tissular equilibrium of the radiated rectum and supplying the area with a sound, vascular sigmoid pedicle graft. While this improves tissue vitality locally, it restores rectal function to a near-normal preradiation level and preserves the previously intact sphincter muscles. The concept of this repair is very sound, and its implementation is greatly facilitated technically by the use of mechanical suture instruments. In this presentation, we describe and show the use of stapling instruments in achieving a three-stage repair of a rectovaginal fistula with Bricker and Johnston's technique.
