Laparascopically assisted vaginal resection of rectovaginal endometriosis.

Abstract

We wanted to establish a technique of laparoscopically assisted radical vaginal surgery for deep endometriosis of the rectovaginal septum with extensive rectal involvement. The procedure is started by vaginally excising the involved area which is left on the rectum, followed by bilateral dissection of the pararectal and retrorectal spaces. Para- and retrosigmoido-rectal spaces are developed laparoscopically along the coccygeosacral bone and medially to the pelvic splanchnic nerves toward the para- and retrorectal openings that were made transvaginally. Rectal transection is done with a laparoscopic stapling device caudal to the endometriotic lesion. Using a suprapubic minilaparotomy, the bowel is transected cranial to the lesion and reintroduced into the abdomen, and a transanal circular stapler anastomosis is done. Thirty-four women had this procedure. The mean distance of the anastomosis was 4 cm above the anus. None required ileostomy or colostomy and no major complications were noted. The combination of laparoscopic and vaginal approaches is useful for removing extensive endometriotic infiltration of the rectosigmoid; bladder and rectal function and fertility can be preserved.
