INTRODUCTION: The aim of this study is to accomplish a systematic review on the surgical techniques available for male-to-female gender assignment surgery (MtoF GAS) published in the last 15 years, from January 2002 to May 2017, assessing advantages and disadvantages.
EVIDENCE ACQUISITION: A specific search on MEDLINE, Scopus and Web of Science databases included vaginoplasty for gender exchange. Preoperative (age, gender, body mass index, prior surgery), intraoperative (mean operating time, intraoperative complications, transfusion rate, conversion rate), postoperative (hospital stays, readmission rate, early and late complication rate), postoperative sexual activity, subjective satisfaction, vaginal depth, and long-term outcomes (vaginal stenosis, prolapse, dyspareunia and labial abscess) data of vaginoplasty for sexual exchange were collected. 29 articles were included (2.402 patients).
EVIDENCE SYNTHESIS: Out of the 29 papers, 19 studies assessed penile skin inversion and 10 evaluated intestinal vaginoplasty. No comparative studies were found. Penile skin inversion vaginoplasty reported slightly shorter operative time compared to intestinal vaginoplasty (109-420 vs 145-420 minutes). Intraoperative complications for penile skin inversion vaginoplasty not exceeded an incidence of 10%. No significant differences in terms of postoperative complications or hospitalization time were reported. Intestinal vaginoplasty provides a deeper neovagina. Female Sexual Function Index score was significantly higher in patients undergoing intestinal vaginoplasty.
CONCLUSIONS: A standardized data collection may allow a better understanding of effectiveness and outcomes of different techniques.
