Left: Intraoperative picture, showing the opened vagina (A) and rectum (B). The Mayo anterior retractor is pulling up the bladder. Agraphes are clearly identified, both in vagina and rectum (white arrows). Right: The drawing schematizes the wrong procedure performed at the time of the first colorectal anastomosis. The staple-gun is passed through the posterior wall of the vagina and rectal pursue string, then it is connected to the colonic stump: firing causes the formation of a vaginal-colonic cloaca.
