Neovagina con sigma: A propósito de dos casos*

made a neovagina, using a segment of sigma and preserving the walls of the former vagina. The surgical technique we used, consisted in the abdominoperineal descent of the segment of sigmoid colon and anastomosis with the back wall of the former vagina and the perineum; after that, we split the intervaginal septum, linking these two structures and reaching a lonely introitus vaginae. The hormonal treatment for the girl with mixed gonadal dysgenesis with estrogen and progestogen induces normal menstruations; we only use estrogen for the patient with Morri’s Syndrome. The histology showed that there were dysgenetic gonadals in one of the patients and testicular tissue without gonadal elements. Both girls have had a good evolution, with no problems and an excellent aesthetic and functional result.
