Total laparoscopic sigmoid vaginoplasty

The Vaginal Microbiome of Transgender and Gender Nonbinary Individuals

Purpose

The goal of this preliminary study is to describe the vaginal microbiome of transgender and gender nonbinary (TGNB) individuals using nonculture-based techniques. TGNB individuals may undergo gender-affirming surgical procedures, which can include the creation of a neovagina. Little is known about microbial species that comprise this environment in states of health or disease.

Methods

In this pilot study, vaginal swabs were self-collected from 15 healthy self-identified TGNB participants (age 26-69 years) and 8 cisgender comparator participants (age 27-50 years) between 2017 and 2018. Next-generation 16S ribosomal RNA sequencing was used to profile individual bacterial communities from all study samples.

Results

The TGNB cohort demonstrated significantly higher intraindividual (alpha) diversity than the cisgender group (p=0.0003). Microbial species commensal to the gut and skin were identified only in specimens from TGNB participants. Although Lactobacillus species were dominant in all cisgender comparator samples, they were found at low relative abundance (≤3%) in TGNB samples.

Conclusion

In this study, specimens collected from neovaginas showed increased alpha diversity and substantially different composition compared with natal vaginas. In contrast to natal vaginas, neovaginas were not dominated by Lactobacillus, but were hosts to many microbial species. Studies that help to improve our understanding of the neovaginal microbiome may enable clinicians to differentiate between healthy and diseased neovaginal states.

[New S2k guideline "Surgical techniques for gender incongruence"]

BACKGROUND

Various techniques for the surgical treatment of gender incongruence (GI) have been available for years. The spectrum is broad and covers various specialties. In recent years, there has been an increase in the number of clinics offering body-modifying procedures. This has led to a considerable variation in methods in some cases. Although the topic has recently found its way more and more into teaching and the relevant specialist literature, there are still no evidence-based recommendations on the various techniques.

AIM

A compendium of established surgical techniques was to be compiled, containing recommendations on indication, performance and aftercare as well as complication management and subjecting them to a consensus-based evaluation.

MATERIALS AND METHODS

In accordance with "Arbeitsgemeinschaft der Wissenschaftlichen Medizinischen Fachgesellschaften" (AWMF) regulations, the guideline was developed at level S2k, i.e., it is consensus based. The guideline group was founded in February 2019 in a formal constituent meeting. A total of 14 medical societies and 2 interest groups were recruited for the guideline work. In the end, two consensus meetings were held, which was due to the large number of recommendations and background texts to be adopted.

RESULTS

The guideline focuses on the choice and applicability of surgical techniques as well as the wishes of those seeking treatment and protection of fertility. There is a wide variety of methods and treatment goals for each individual. Taking into account medical standards, recommendations, and contraindications, an optimal result that minimizes individual suffering can be achieved together with the person seeking treatment.

CONCLUSION

The content of the guideline represents a unique compendium of surgical methods, recommendations for the selection of procedures, and common indications in the field of body-modifying surgery for gender incongruence.

Genital gender-affirming surgery for transgender women

Transgender women may opt for genital gender-affirming surgery (gGAS), which comprises bilateral orchiectomy, gender-affirming vulvoplasty, or vaginoplasty. Vaginoplasty is chosen most frequently in this population, penile inversion vaginoplasty being the surgical gold standard. In selected cases, skin graft vaginoplasty, intestinal vaginoplasty, or peritoneal vaginoplasty may be indicated. In this article, we discuss the various types of gGAS for transgender women, (contra)-indications, intraoperative considerations, techniques, surgical outcomes, and postoperative patient-reported outcomes.

Principles and outcomes of gender-affirming vaginoplasty

Vaginoplasty is the most frequently performed gender-affirming genital surgery for gender-diverse people with genital gender incongruence. The procedure is performed to create an aesthetic and functional vulva and vaginal canal that enables receptive intercourse, erogenous clitoral sensation and a downward-directed urine stream. Penile inversion vaginoplasty (PIV) is a single surgical procedure involving anatomical component rearrangement of the penis and scrotum that enables many patients to meet these anatomical goals. Other options include minimal-depth, peritoneal and intestinal vaginoplasty. Patient quality of life has been shown to improve drastically after vaginoplasty, but complication rates have been documented to be as high as 70%. Fortunately, most complications do not alter long-term postoperative clinical outcomes and can be managed without surgical intervention in the acute perioperative phase. However, major complications, such as rectal injury, rectovaginal fistula, and urethral or introital stenosis can substantially affect the patient experience. Innovations in surgical approaches and techniques have demonstrated promising early results for reducing complications and augmenting vaginal depth, but long-term data are scarce.

An Alternative Option for Gender-Affirming Revision Vaginoplasty: The Tubularized Urachus-Peritoneal Hinge Flap

INTRODUCTION

Gender-affirming peritoneal vaginoplasty has been described, and previous descriptions are modifications of the Davydov technique.

AIM

To describe our alternative technique for gender-affirming peritoneal vaginoplasty (PV) using a single-pedicled, urachus-peritoneal hinge flap, discussing proposed advantages.

METHODS

Retrospective review of all consecutive transfeminine patients with neovaginal shortening after prior penile inversion vaginoplasty (PIV) who underwent our PV technique from May 2019 to July 2022.  PV was performed via combined transperineal and laparoscopic (robot-assisted) approaches. After spatulation of the neovaginal remnant, a midline, inferiorly based urachus-peritoneal hinge flap was elevated craniocaudally from the umbilicus to the mid-posterior bladder. The free end of the flap was flipped posteriorly and sutured to posterior edge of the open canal remnant, forming a peritoneal pouch. The lateral edges of the pouch were sutured together for water-tight closure. Patients resumed dilation on POD 6 and douching on POD 10.

MAIN OUTCOME MEASURES

Ten transfeminine patients underwent PV, with good outcomes. We measured: Pre-op penile and scrotal skin lengths, intra-op tubularized scrotal skin length, pre and post-op vaginal depth and width (immediate and at last follow-up).

RESULTS

Pre-op: mean neovaginal depth was 9.2cm (SD 1.5); width was 12cm. Immediate post-op: mean depth was 15.1 cm (SD 2.2 cm, mean net increase: 5.9 cm). At mean follow-up of 18.3 months, mean depth was 12.5 cm (SD 2.1 cm, mean net increase: 3.3 cm) and width was 12 cm. There were no immediate post-op complications. Eight (80%) of the 10 patients report satisfactory vaginal receptive intercourse. The other 2 have not yet attempted vaginal receptive intercourse.

CLINICAL IMPLICATIONS

Advantages of the proposed technique over existing techniques include no tension on peritoneal suture lines and total exclusion of the rectum.

STRENGTHS AND LIMITATIONS

Strengths include a short learning curve for urologic surgeons with robotic experience.  The study is limited by small sample size.

CONCLUSIONS

Our PV technique is a safe and effective option for salvage peritoneal vaginoplasty after primary PIV. Smith SM, Yuan N, Stelmar J, et al. An Alternative Option for Gender-Affirming Revision Vaginoplasty: The Tubularized Urachus-Peritoneal Hinge Flap. Sex Med 2022;10:100572.

Real-time indocyanine green fluorescent angiography in laparoscopic sigmoid vaginoplasty to assess perfusion of the pedicled sigmoid segment

OBJECTIVE

To assess the feasibility of intraoperative use of indocyanine green (ICG) fluorescent angiography in laparoscopic intestinal vaginoplasty to determine intestinal segment perfusion and viability.

DESIGN

Intestinal vaginoplasty may be performed as a vaginal (re)construction procedure. During surgery, a pedicled intestinal segment is transferred caudally to line the neovaginal cavity. Most commonly, a sigmoid or ileal segment is used. In obtaining adequate mobility of the segment, arterial structures sometimes have to be sacrificed, with possible detrimental effects on segment perfusion and subsequently viability. ICG may be used as an aid to assess segment perfusion. We present a case series of six consecutive patients who underwent intestinal vaginoplasty with intraoperative use of ICG.

SETTING

Tertiary university hospital.

PATIENT(S)

Six transgender women undergoing laparoscopic sigmoid vaginoplasty with intraoperative use of ICG from October 2017 to October 2018.

INTERVENTION(S)

Intraoperative use of ICG in laparoscopic sigmoid vaginoplasty to determine sigmoid segment perfusion and viability.

MAIN OUTCOME MEASURE(S)

Value and feasibility of ICG in this reconstructive procedure.

RESULT(S)

Intraoperative use of ICG demonstrated segment viability in five patients. In one patient, vascularization of the segment was deemed to be inadequate and reconstruction was aborted.

CONCLUSIONS

ICG fluorescent angiography may be used intraoperatively to assess perfusion of the pedicled sigmoid segment during sigmoid vaginoplasty.

Application of mesocolon rotation and reverse puncture in total laparoscopic sigmoid vaginoplasty

The aim of the present study was to explore the clinical efficacy of mesocolon rotation and reverse puncture in total laparoscopic sigmoid vaginoplasty (LSV). The clinical data of 11 patients (unmarried, n=4; married, n=7) with congenital absence of a vagina who underwent treatment of total laparoscopic sigmoid vaginoplasty at the First Affiliated Hospital of Xinjiang Medical University (Urumqi, China) between March 2013 and March 2016 were retrospectively analyzed. In all patients, the surgical method included sigmoid mesocolon rotation and reverse puncture. The vaginal depth, the first sexual intercourse time and female sexual function indexes were recorded. The average operation time was 187±19 min, the average intra-operative blood loss was 132±24 ml, the time to the first meal after surgery was 4.3±1.1 days, the average post-operative hospital stay was 7.5±1.2 days, the post-operative short-term complication rate was 36.3% and the time to the first sexual intercourse was 3.0±0.3 months. The post-operative follow-up results indicated that the anatomical standard was reached in all of the 11 patients. Among the seven married patients, five patients were satisfied with their sex lives after the operation. In terms of psychosexual desire, only one married patient felt no sexual arousal. The other married patients had good sexual relations, function and satisfaction. In conclusion, the application of mesocolon rotation and reverse puncture in total LSV is safe and feasible.

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

Supplemental Digital Content is available in the text.

Background:

Current male-to-female (MtF) sex-reassignment-surgery techniques have not been fully successful to achieve the ideal objectives. The ordeal of multiple procedures, associated complications, and suboptimal results leads to high rate of dissatisfaction. We have tried to overcome functional inadequacy and address the esthetic issues for outer genitalia and vagina with our innovative “true shape sigma-lead SRS: Kaushik’s technique,” which has now become the technique of choice for MtF genital SRS for our patients.

Methods:

Between April 2007 and April 2017, authors performed 386 sigma-lead SRS in MtF transsexuals. Results were analyzed based on complications, resurgeries, and esthetic/functional outcomes. Corrective SRS using rectosigmoid constituted 145 cases and is not a part of this study.

Results:

Maximum follow-up was 7 years (average 34 months). Seventy-eight (20.2%) patients had complications, majority being minor (97.4%). Forty-four (11.4%) required resurgeries, 10 (2.6%) were corrective for introital stricture and mucosal prolapse, whereas 34 (8.8%) opted for optional minor esthetic enhancement. The overall satisfaction rate for cosmetic and functional outcomes was 4.7 out of 5. In addition to review of the literature, innovations in the technique have been explained.

Conclusions:

Kaushik’s sigma-lead MtF SRS technique is a step short to become the gold standard of genital SRS because it has proven to be safe and reliable. It allows faster healing, minimal dilation, and nearly natural cosmetic results in the form of clitoris/clitoral hood, labia minora, labia majora along with self-lubricating, fully deep, and sensate neovagina with orgasmic capabilities. This is perhaps the largest reported series of rectosigmoid use in transsexuals carried out for primary vaginoplasty.
