The perineal dissection and creation of the neovaginal canal is the most challenging aspect of the penile inversion vaginoplasty (PiV) and poor visualization can lead to surgical complications. An incomplete dissection also results in a foreshortened neovagina, increased risk for vaginal stenosis and need for excessive postoperative dilations. Here we present the results of our first 15 patients performed at our intuition utilizing our robot assisted PiV (RAPiV). METHODS 15 transgender patients who were already living as females presented to our institution from 1/2016 to 10/2016, and underwent our previously defined RAPiV. Briefly, the RAPiv is performed in the low lithotomy position and the penis is degloved through a circumcision incision. An additional perineal incision is made to the bulbar urethra. The dissected penis, urethra, neurovascular bundle, glans and corpora are delivered through the perineal incision (Figure 1a). We spare the dorsal aspect of the tunica of the corpora cavernosa to reduce risk of glans necrosis. Four robotic ports were placed and the abdomen was insufflated (1b) and robot docked. Denonviller's fascia is opened (1c) and the abdominal dissection is continued to the peritoneal one (1d), the neovagina is passed into robotic field (1e) and pexed to the anterior reflection of the posterior peritoneum (1f). The peritoneal reflection is then closed (1g). We then complete the labioplasty and clitoroplasty. RESULTS The average operative time for RAPiV was 5.8 hours (5-7), 8/15 (53%) required mobilization of additional tissue flaps (4/15, 27%) or underwent concomitant abdominoplasty and skin graft harvest (4/15 27%) to supplement penile skin. EBL was 386cc (100-600) and LOS was 3.7 (2-6). Average postoperative vaginal depth was 11.3cm (10.2-12.7). Two patients had complications, 1 dehiscence of labioplasty treated with conservative therapy and 1 had loss of neovagina depth and distal urethral stenosis secondary to wound infection requiring debridement. CONCLUSIONS We have performed 15 cases utilizing our novel method for robot assisted penile inversion vaginoplasty. Under direct visualization the neovaginal canal is created. This technique achieves maximal vaginal length in a reproducible manner. © 2017FiguresReferencesRelatedDetails Volume 197Issue 4SApril 2017Page: e1075-e1076 Advertisement Copyright & Permissions© 2017MetricsAuthor Information Brenton Armstrong More articles by this author Aaron Weinberg More articles by this author Kiranpreet Khurana More articles by this author Jamie Levine More articles by this author Lee Zhao More articles by this author Expand All Advertisement Advertisement PDF downloadLoading ...
