Operative Genitalangleichung bei Mann-zu-Frau-Transsexualität: Gibt es Leitlinien oder Standards?

Abstract

In 2011 the WPATH (World Professional Association for Transgender Health) published the 7th version of their "Standards of Care" for diagnosis and treatment of transsexual people. In face of further recent peer-reviewed reports of experienced centres on surgical sex reassignment it should be examined whether or not genital sex reassignment in male-to-female transsexuals actually can be based on evidence-based guidelines or standards. The indication for surgery is widely standardised and evidence-based. Most critical steps of the operation are also founded on grade B recommendations. Most experienced authors rely on penoscrotal pedicled flaps for neovaginal lining. The topic of ideal reconstruction of the vulva, especially the clitoro-labial complex is still a field of debate. Due to the high frequency of further corrective surgeries which exceeds 50% in most experienced centres, some authors prefer a primary 2-step procedure for genital reassignment. The indication and principal operative steps in surgical genital reassignment in male-to-female patients rely on evidence-based recommendations. By respecting these recommendations subjective success rates of over 80% can be expected.
