TAMIS-Flap Technique: Full-thickness Advancement Rectal Flap for High Perianal Fistulae Performed Through Transanal Minimally Invasive Surgery.

The formation of an advancement rectal flap could be technically demanding in the presence of high perianal of rectovaginal fistula, and the outcomes could be frustrated by the inadequate view, bleeding and a poor exposure through the standard transanal approach. The application of the transanal minimally invasive surgery (TAMIS) to the advancement rectal flap procedure could overcome these difficulties. In the lithotomy position, a partial fistulectomy was performed and the internal opening was closed. A full-thickness flap was mobilized initially through the classic transanal approach. Subsequently, the TAMIS port was inserted and the mobilization of the flap was carried on proximally for as long as required. The laparoscopic visualization allowed a perfect view, a proper orientation of the flap and accurate hemostasis. The TAMIS-flap procedure seems a promising technique to perform a long advancement rectal flap to treat high perianal or rectovaginal fistulae (Video, Supplemental Digital Content 1, http://links.lww.com/SLE/A208).
