Sigma-lead Male-to-Female Gender Affirmation Surgery: Blending Cosmesis with Functionality

Systematic Review of Neovaginal Prolapse After Vaginoplasty in Trans Women

Background and objective

Most trans women are requesting a gender affirming genital surgery by vulvovaginoplasty. However, long-term complications such as genital prolapse are unknown. Through this systematic review, our objective was to provide an overview of the published outcomes related to genital prolapse after vaginoplasty in male-to-female transgender individuals, including prevalence, identified risk factors, and treatment.

Methods

We included all studies reporting genital prolapse rates following vulvovaginoplasty from 1995 to the present. Only studies that focused on the transgender population were included. The primary outcome was the genital prolapse rate. The secondary outcomes included risk factors and treatment of genital prolapse after vulvovaginoplasty. Article selection was performed by two independent reviewers.

Key findings and limitations

Twenty-four studies, involving 3166 patients, that presented sufficient data were analyzed. The mean age at the time of vulvovaginoplasty was 37.7 yr. The mean follow-up time was 22.5 mo. Most of the studies were retrospective case series of low to intermediate quality. The penile skin inversion technique was the most frequently employed method (in 85% of the 3166 patients). The prevalence of prolapse ranged from 0% to 7% with the penile skin inversion technique and from 1.6% to 22.7% with intestinal vaginoplasty. Upon consolidating the results, an overall rate of 2.7% was observed. Specifically, the prolapse rate within the penile inversion technique subgroup was 2.5%, while the rate for the intestinal-derived neovagina subgroup was 3.5%. The only significant risk factor identified was a high body mass index at the time of surgery. The most employed intraoperative technique to prevent neovaginal prolapse involves fixation to the sacrospinous ligament, coupled with systematic vaginal packing. Few case reports addressed the surgical treatment of neovaginal prolapse, predominantly using open abdominal or laparoscopic approaches. None of these considered transvaginal or perineal approaches. No recommendation exists about the use of vaginal prosthesis.

Conclusions and clinical implications

Neovaginal prolapse in male-to-female transgender patients remains a rare complication, but its significance is growing as the transgender population ages. Scarce information is available regarding preventative techniques and treatments, necessitating further exploration, hampered by its infrequent occurrence.

Patient summary

Neovaginal prolapse in male-to-female transgender patients is a rare complication, with the only recognized risk factor being a high body mass index. However, its importance is growing with the aging of the transgender population. Long-term complications, preventive techniques, and management of these prolapses need to be explored through further research.

Gender-Affirming Surgery in Low- and Middle-Income Countries: A Systematic Review

Objectives: Fewer than one-fifth of all studies on gender-affirming care originate from low- and middle-income countries (LMICs). This is the first systematic review to examine surgical demographics and outcomes following gender-affirming surgery (GAS) in LMICs. Methods: Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, five databases were systematically searched for original studies and case series on GAS within LMIC settings. Excluded reports included animal studies, non-English language studies, secondary studies including reviews, individual case reports and conference abstracts. Results: This review includes 34 studies involving n = 5064 TGNB individuals. Most studies (22, 64.7%) were from upper-middle-income countries, followed by lower-middle-income countries (12, 35.3%). A total of 31 studies (91.2%) reported on post-operative outcomes. Of n = 5013 patients who underwent GAS, 71.5% (n = 3584) underwent masculinizing and 29.5% (n = 1480) underwent feminizing procedures. The predominant procedures were metoidioplasty (n = 2270/3584, 63.3%) and vaginoplasty (n = 1103/1480, 74.5%). Mean follow-up was 47.7 months. In patients who underwent metoidioplasty, 6.8% (n = 155) of patients experienced a complication and 6.3% (n = 144) underwent revision surgery. In patients who underwent vaginoplasty, 11.5% (n = 127) of patients experienced a complication and 8.5% (n = 94) underwent revision surgery. Of the studies (25/34, 73.5%) that reported on quality of life and post-operative satisfaction, the majority showed marked improvements in psychosocial and functional outcomes. Notably, no post-surgical regret was reported among the surveyed patients. Conclusions: Existing literature on GAS in LMICs remains scarce and is concentrated in select institutions that drive specific procedures. Our review highlights the low reported volumes of GAS, variability in surgical outcomes and quality of life.

[Vulvoplasty after gender-affirmating genital surgery]

Functional and aesthetic results after vaginoplasty in sexual reassignment surgery have improved in recent years. Improved surgical techniques, well-established expert teams and a growing demand for and interest in this type of surgery are some of the reasons for these results. However, there is a growing demand for genital cosmetic surgery, not only among cis women, but also among trans women. The main shortcomings in results are therefore presented and listed. The aesthetic revision surgery techniques specifically indicated are described. Labiaplasty and clitoridoplasty appear to be the two main requests for secondary surgery following trans vaginoplasty.

Vaginal self-lubrication following peritoneal, penile inversion, and colonic gender-affirming vaginoplasty: a physiologic, anatomic, and histologic review

INTRODUCTION

Vaginal self-lubrication is central to the sexual satisfaction and healthy genitourinary function of patients who have undergone gender-affirming vaginoplasty (GAV). Secretory capacities of different neovaginal lining tissues have been variably described in the literature, with little evidence-based consensus on their success in providing a functionally self-lubricating neovagina. We review the existing neovaginal lubrication data and the anatomy, histology, and physiology of penile and scrotal skin, colon, and peritoneum to better characterize their capacity to be functionally self-lubricating when used as neovaginal lining.

OBJECTIVES

The study sought to review and compare the merits of penile and scrotal skin grafts, spatulated urethra, colon, and peritoneal flaps to produce functional lubrication analogous to that of the natal vagina in the setting of GAV.

METHODS

We conducted a systematic review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Medline, EMBASE, ClinicalTrials.gov, and the Cochrane Library databases were searched for peer-reviewed studies published prior to December 12, 2022, that (1) included data specific to transfeminine individuals; (2) were full-text randomized controlled studies, case reports, case series, retrospective cohort studies, prospective cohort studies, qualitative studies, and cross-sectional studies; and (3) included specific discussion of vaginal lubrication or fluid secretion following GAV utilizing penile skin, colonic tissue, or peritoneum.

RESULTS

We identified 580 studies, of which 28 met our inclusion criteria. Data on neovaginal lubrication were limited to qualitative clinician observations, patient-reported outcomes, and satisfaction measures. No studies quantifying neovaginal secretions were identified for any GAV graft or flap technique. Anatomically, penile and scrotal skin have no self-lubricating potential, though penile inversion vaginoplasty may produce some sexually responsive secretory fluid when urethral tissue is incorporated and lubricating genitourinary accessory glands are retained. Colonic and peritoneal tissues both have secretory capacity, but fluid production by these tissues is continuous, nonresponsive to sexual arousal, and likely inappropriate in volume, and so may not meet the needs or expectations of some patients. The impact of surgical tissue translocation on their innate secretory function has not been documented.

CONCLUSIONS

None of penile/scrotal skin, colon, or peritoneum provides functional neovaginal lubrication comparable to that of the adult natal vagina. Each tissue has limitations, particularly with respect to inappropriate volume and/or chronicity of secretions. The existing evidence does not support recommending one GAV technique over others based on lubrication outcomes. Finally, difficulty distinguishing between physiologic and pathologic neovaginal fluid secretion may confound the assessment of neovaginal self-lubrication, as many pathologies of the neovagina present with symptomatic discharge.

Cosmetic Revision Surgeries after Transfeminine Vaginoplasty

BACKGROUND

Vaginoplasty is the most frequent genital gender-affirming surgery. Although both functional and aesthetic outcomes after transfeminine vaginoplasty have improved over the years, cosmetic revision surgeries demand after transfeminine vaginoplasty appears to be increasing and requires updated knowledge.

METHODS

All patients who underwent vulvar cosmetic revision surgeries at our institution following transfeminine vaginoplasty from January 2014 to April  2022 were studied. The prevalence, topography and surgical techniques of cosmetic revision surgeries after transfeminine genital gender-affirming surgery were examined using clinical charts review and statistical analysis.

RESULTS

During the study period, 354 patients underwent gender-affirming vaginoplasty at our single institution (212 penile inversion vaginoplasty, 122 colovaginoplasty and 20 penile inversion vaginoplasty with scrotal skin graft patients). Forty out of these 354 patients (11.29%) required cosmetic revision surgery after transfeminine vaginoplasty; additionally, 44 patients with vaginoplasty performed at other centres also underwent vulvar cosmetic revision surgery at our clinic during the study period. From all performed cosmetic revision surgeries, most of them (31.42%) were labia corrections, followed by clitoris (23.26%) repair surgeries. Mons Venus (10.20%), urethral meatus (9.38%), spongiosus tissue remnants (8.57%) and introitus (6.53%) revisions followed in frequency. Corrections of peri-inguinal scars (5.30%), anterior commissure (2.84%) and inferior fourchette (2.42%) were less prevalent. No differences were found among the different studied vaginoplasty techniques regarding cosmetic revision surgery prevalence or topography following transfeminine vaginoplasty (p < 0.05).

CONCLUSIONS

Cosmetic revision surgeries after transfeminine vaginoplasty are frequent. In our large and long-term cohort study, labiaplasty followed by clitoroplasty were found as the most required cosmetic revision surgical procedures. Further multicentre, prospective and controlled studies are necessary to improve cosmetic outcomes and scientific evidence after transfeminine vaginoplasty.

Surgical satisfaction and quality of life outcomes reported by transgender men and women at least one year post gender-affirming surgery: A systematic literature review

Background

Many transgender women and men undergo gender-affirming surgeries. Existing work shows that early surgery outcomes are generally positive, suggesting high surgical satisfaction and positive quality of life outcomes. Less work, however, examines these outcomes in the longer-term.

Aims

To conduct a systematic literature review into the longer-term (i.e., ≥ 1 year) surgical satisfaction and quality of outcomes following various forms of gender-affirming surgery in transgender populations. Specifically, we aim to examine research on such outcomes at least one-year post gender-affirming chest, genital, facial, vocal cord, and Adam's apple removal surgeries.

Methods

Studies were identified through Google Scholar, PsycINFO, Scopus, and PubMed databases, as well as through Google Scholar search alerts. We considered all studies published until October 2021. Two reviewers extracted data from suitable studies using Covidence. Both reviewers also independently assessed the identified studies' risk of bias and strength of evidence.

Results

Seventy-nine low quality (e.g., small sample sizes, lack of control/comparison groups) studies suggest that most transgender patients are satisfied with surgical outcomes when assessed at least one-year post-surgery. Low quality research also indicates that transgender women and men typically report positive psychological and sexual wellbeing post-surgery, and similar wellbeing outcomes as those who have not had surgery.

Discussion

To the best of our knowledge, this literature review is the first to critically summarize and evaluate all published studies on the longer-term quality of life outcomes following chest, genital, facial, voice and Adam's apple removal surgeries for transgender women and men. While the results suggest promising surgical satisfaction and quality of life outcomes following surgery, many studies only draw on small samples, and most studies do not allow for causal conclusions. Further, few studies have compared surgical outcomes between transgender women and men. We conclude by offering concrete suggestions for future research.

Complications and Patient-reported Outcomes in Transfemale Vaginoplasty: An Updated Systematic Review and Meta-analysis

Supplemental Digital Content is available in the text.

Background:

Vaginoplasty aims to create a functional feminine vagina, sensate clitoris, and labia minora and majora with acceptable cosmesis. The upward trend in the number of transfemale vaginoplasties has impacted the number of published articles on this topic. Herein, we conducted an updated systematic review on complications and patient-reported outcomes.

Methods:

A update on our previous systematic review was conducted. Several databases including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus were assessed. Random effects meta-analysis and subgroup analyses were performed.

Results:

After compiling the results of the update with the previous systematic review, a total of 57 studies pooling 4680 cases were included in the systematic review, and 52 studies were used in the meta-analysis. Overall pooled data including any surgical technique showed rates of 1% [95% confidence interval (CI) <0.1%–2%] of fistula, 11% (95% CI 8%–14%) of stenosis and/or strictures, 4% (95% CI 1%–9%) of tissue necrosis, and 3% (95% CI 1%–4%) of prolapse. Overall satisfaction was 91% (81%–98%). Regret rate was 2% (95% CI <1%–3%). Average neovaginal depth was 9.4 cm (7.9–10.9 cm) for the penile skin inversion and 15.3 cm (13.8–16.7 cm) for the intestinal vaginoplasty.

Conclusions:

Transfemale vaginoplasty is a key component of the comprehensive surgical treatment of transfemale patients with gender dysphoria. Over time, we will see an increased demand for these procedures, so adequate surgical training, clinical/surgical experience, and research outcomes are required, as we continue to strive to provide the best care possible for a population in need.
