[Brain characteristics of transgender individuals and consequences of gender assignment treatment]. / Características cerebrales de las personas transexuales y consecuencias del tratamiento de asignación de género.

The differences between the male and female brain in cisgender individuals, those in whom there is no incongruence between the so-called biological sex and the perceived sex, are known. The genetic basis that underlies the differences observed in the brains of transgender individuals compared to cisgender individuals is also becoming known. In transgender individuals, there is a fundamental change in the connectivity of neurons in the body perception network, which may give rise to gender dysphoria. This knowledge allows for the characterization of the transgender condition and distinguishes it from transgender identities such as non-binary gender, gender fluidity, or genderqueer. Articles published assume, from the perspective of depathologization imposed by Gender Ideology, that these differences are due to a different sexual development. The societal acceptance of this perspective over the last two decades paved the way for medical interventions aimed at affirming the perceived gender, different from the genetic sex, through the continuous administration of cross-sex hormones and, in some cases, mutilating surgery. In adolescents and children, affirmation treatment of the perceived gender begins with puberty blockers, which have negative consequences for ossification and growth. The importance and irreversibility of these 'side effects' require the utmost rigor and complete information about them. Spanish law pushes the ideology to the maximum, infringing on the rights of transgender individuals. Medical ethics emphasize the necessity - the right - of a medical and psychological diagnosis, free from ideological approaches, before initiating what is being called treatment. This includes the right to information, prior to consent, about the positive and negative effects of hormonal administration. It also includes the right to the recognition of diversity among transgender individuals, especially the right to research that allows for treating the brain without altering the body. These rights must be recognized and demanded by the laws.

Power, policy, and transgender identities: A case study of gatekeeping by mental health professionals in accessing gender affirming surgeries in India.

BACKGROUND: Transgender individuals seeking gender-affirming surgeries (GAS) are often denied or delayed by mental health professionals (MHPs). Studies on the gatekeeping of GAS have been mainly conducted in the Global North and primarily focus on the perspectives of health professionals. This case study from India incorporates health professional, community, advocate, and activist perspectives to contribute new evidence about MHP gatekeeping in GAS. The study aims to examine the role of power and gender in MHP gatekeeping of GAS in India. METHODS: A qualitative multi-method case study including thematic analyses of key informant interviews (n = 9) and policy analysis using the policy triangle framework. RESULTS: Health professionals and transgender persons participate in the construction, performance, and reproduction of gender indicating the persistence of gender normativity in India which enables gatekeeping by MHPs. However, evidence suggests some signs of a change from binormativity to a culturally intelligible and historically familiar "trinormativity". CONCLUSION: To understand MHP gatekeeping, there is a need to contextualise this example of biopower within the larger social construction of gender within which MHPs operate. A transition from binormativity to "trinormativity" enables MHP gatekeeping of transgender persons seeking GAS. This risks creating new forms of gender-related oppression, such as new hierarchies and class differences between the gender binary and the "third gender".

Urological focus on gender affirmation surgery.

BACKGROUND: Gender affirmation surgery plays an important role in the treatment of gender dysphoria. These procedures play a vital role in aligning individuals' physical characteristics with their gender identity, resulting in improved mental health and overall wellbeing. OBJECTIVE: This article provides an overview of genital gender affirmation surgeries, focusing on the available options and appropriate referral criteria for general practitioners and surgeons. DISCUSSION: Gender affirmation surgery necessitates a multidisciplinary approach, emphasising patient readiness, clear surgical preferences, hormonal transition and modifiable risk factors. The two primary methods for assessing patient appropriateness, the World Professional Association for Transgender Health (WPATH) guidelines and the informed consent model, are discussed. This article summarises surgical options for both trans-male and trans-female individuals, outlining procedures, benefits and potential complications. Gender affirmation surgery is set to play an increasingly important role in the management of gender dysphoria. By understanding the available options and referral processes, primary care physicians will be able to optimise care for these patients.

Characteristics of a transgender and gender-diverse patient population in Utah: Use of electronic health records to advance clinical and health equity research.

Transgender and gender-diverse (TGD) people, individuals whose gender identity differs from their sex assigned at birth, face unique challenges in accessing gender-affirming care and often experience disparities in a variety of health outcomes. Clinical research on TGD health is limited by a lack of standardization on how to best identify these individuals. The objective of this retrospective cohort analysis was to accurately identify and describe TGD adults and their use of gender-affirming care from 2003-2023 in a healthcare system in Utah, United States. International Classification of Disease (ICD)-9 and 10 codes and surgical procedure codes, along with sexual orientation and gender identity data were used to develop a dataset of 4,587 TGD adults. During this time frame, 2,985 adults received gender-affirming hormone therapy (GAHT) and/or gender-affirming surgery (GAS) within one healthcare system. There was no significant difference in race or ethnicity between TGD adults who received GAHT and/or GAS compared to TGD adults who did not receive such care. TGD adults who received GAHT and/or GAS were more likely to have commercial insurance coverage, and adults from rural communities were underrepresented. Patients seeking estradiol-based GAHT tended to be older than those seeking testosterone-based GAHT. The first GAS occurred in 2013, and uptake of GAS have doubled since 2018. This study provides a methodology to identify and examine TGD patients in other health systems and offers insights into emerging trends and access to gender-affirming care.

Dynamism of andrological surgery in France: Evolution of procedures over 10 years.

INTRODUCTION: Andrology and urogenital reconstruction are emerging disciplines in French urology. The aim of our study was to evaluate the evolution of andrological surgical procedures over the period 2013-2022 using national data. MATERIALS AND METHODS: We collected national common classification of medical acts (CCAM) coding data for all procedures involving andrological surgery from the Scansanté internet platform set up by the Technical Agency for Information on Hospitalisation, which collects prospectively from healthcare structures all procedures coded according to CCAM coding. All surgical procedures in andrology were selected. The inclusion period extended from 2013 to 2022. RESULTS: In 10 years, the number of vasectomies has increased tenfold, with 29,890 cases in 2022. Vaso-vasostomies remain marginal, with 80 cases per year. Trans-identity surgeries are rising sharply. Vaginoplasties have multiplied by 4 (333 in 2022) and masculinising surgeries have multiplied by 10 (234 in 2022). Penile prosthesis surgery has increased slightly over 10 years. The number of testicular biopsies has remained stable over time, as has the number of surgeries for curvature of the penis. CONCLUSION: Two andrological surgeries are showing very strong growth: vasectomy and transgender surgery. The emergence of these 2 activities is linked to societal aspirations. Urologists need to be trained to meet this demand. NIVEAU DE PREUVE: Grade 4.

Does the Internet Provide Quality Information on Metoidioplasty? Using the Modified Ensuring Quality Information for Patients Tool to Evaluate Artificial Intelligence-Generated and Online Information on Metoidioplasty.

BACKGROUND: Public interest in gender affirmation surgery has surged over the last decade. This spike in interest, combined with extensive free online medical knowledge, has led many to the Internet for more information on this complicated procedure. This study aimed to evaluate the quality of online information on metoidioplasty. METHODS: Google Trends in searches on "metoidioplasty" from 2004 to present were assessed. "metoidioplasty" was searched on three popular search engines (Google, Yahoo, and Bing), and the first 100 websites from each search were extracted for inclusion (Fig. 1). Exclusion criteria included duplicates, websites requiring fees, photo libraries, and irrelevant websites. Websites were assigned a score (out of 36) using the modified Ensuring Quality Information for Patients (EQIP) instrument, which grades patient materials based on content (18), identification (6), and structure (12). ChatGPT was also queried for metoidioplasty-related information and responses were analyzed using EQIP. RESULTS: Google Trends analysis indicated relative search interest in "metoidioplasty" has more than quadrupled since 2013(Fig. 2). Of the 93 websites included, only 2 received an EQIP score greater than 27 (6%). Website scores ranged from 7 to 33, with a mean of 18.6 ± 4.8. Mean scores were highest for websites made by health departments (22.3) and lowest for those made by encyclopedias and academic institutions (16.0). Websites with the highest frequency were research articles, web portals, hospital websites, and private practice sites, which averaged scores of 18.2, 19.7, 19.0, and 17.8, respectively. Health department sites averaged the highest content points (11.25), and academic institutions averaged the lowest (5.5). The average content point across all websites was 7.9 of 18. ChatGPT scored a total score of 29: 17 content, 2 identification, and 10 structures. The artificial intelligence chatbot scored the second highest score among all included online resources. CONCLUSIONS: Despite the continued use of search engines, the quality of online information on metoidioplasty remains exceptionally poor across most website developers. This study demonstrates the need to improve these resources, especially as interest in gender-affirming surgery continues to grow. ChatGPT and other artificial intelligence chatbots may be efficient and reliable alternatives for those seeking to understand complex medical information.

Trends of Medicare Reimbursement Rates for Gender-Affirming Surgery Procedures.

BACKGROUND: Awareness of Medicare reimbursement is important for gender-affirming surgeons who treat transgender patients with Medicare. In 2014, Medicare began to provide coverage for medically necessary transition-related surgery. The purpose of this study was to analyze trends in Medicare reimbursement rates for gender-affirming surgery procedures from 2014 to 2022. METHODS: The Medicare Physician Fee Schedule Look-Up Tool provided by the Centers for Medicare and Medicaid Services was used, and the Current Procedural Terminology codes for 43 gender-affirming surgery services were obtained. Monetary units, conversion factors, relative value units (RVUs) for work, facility, and malpractice costs for 30 transmasculine and 13 transfeminine procedures were analyzed. Descriptive statistics were performed to account for inflation and to determine the relative differences between 2014 and 2022. RESULTS: For all gender-affirming surgery procedures covered by Medicare, the average relative difference of monetary units decreased by 2.99% between 2014 and 2022. On average, there was a 3.97% decrease of work-based RVU charges for transmasculine procedures and a 1.73% decrease of work-based RVU charges for transfeminine procedures. After adjusting for inflation, the average relative difference of monetary units for all gender-affirming surgery procedures decreased by 23.42% between 2014 and 2022. CONCLUSIONS: Reimbursement rates for gender-affirming surgery procedures covered under Medicare have decreased over the observed period, and trends in reimbursement rates have not kept up with consumer price index inflation. Gender-affirming surgeons should be conscious of these changes in reimbursement rates and advocate for fairer compensation to promote medical care among an underserved population.

Breast Cancer Screening Recommendations for Transgender Patients: A Review.

Shifting societal attitudes trending toward increased acceptance of transgender people has contributed to a growth in the population of individuals who openly identify as transgender as well as an increase in utilization of gender-affirming surgeries. Therefore, health care providers should work toward increasing their knowledge with respect to the health care needs of the transgender population, particularly given that these individuals often face discrimination in the health care system. Moreover, transgender breast cancer screening rates lag behind breast cancer screening rates for cisgender individuals. We attempt to clarify important terminology about the transgender population and introduce the concept of equity-centered language. We review current transgender breast cancer screening guidelines by using PubMed, Google Scholar, and Google with search terms that included transgender breast cancer guidelines, transgender breast cancer screening guidelines, and transgender cancer screening guidelines. Searches were not filtered based on year of publication, language of publication, or geographic location. We compare the various guidelines as they pertain to both transgender men and transgender women and offer special considerations for upholding inclusivity in the health care field. An easy-to-reference summary of the current transgender breast cancer screening guidelines and the major points of this article were compiled into an original infographic that health care providers can reference to ensure that appropriate care is being offered.

Perioperative risk predictors for gender affirming surgery in the NSQIP database.

INTRODUCTION: Gender affirming surgeries (GAS), such as phalloplasty (PLPs) and vaginoplasty (VGPs), are important aspects of medical care for transgender patients. Here, we aim to better characterize patient demographics and surgical outcomes for PLPs and VGPs using the National Surgical Quality Improvement Program (NSQIP). We hypothesized that frailty indices would be predictive of perioperative PLP and VGP risk and outcomes for PLPs and VGPs. MATERIALS AND METHODS: Primary GAS, specifically PLPs and VGPs performed from 2006-2020 were identified in NSQIP. Baseline frailty was based on NSQIP's modified frailty index (mFI) and preoperative morbidity probability (morbprob) variable. RESULTS: Fifty-eight PLPs and 468 VGPs were identified. The overall 30-day complication rate for PLP was 26%, with 17% of total patients experiencing minor complications and 16% experiencing major complications. The overall, minor, and major complication rates for VGP were 14%, 7%, and 9% respectively. Readmissions and reoperations occurred in 7% PLP and 5% VGP patients. No deaths occurred in either group within 30 days. The mFI scores were not predictive of 30-day complications or LOS. NSQIP morbprob was predictive of 30-day complications for both PLP (OR 4.0, 95% CI 1.08-19.59, p = 0.038) and VGP (OR 2.39, 95% CI 1.46-3.97, p = 0.0005). NSQIP's morbprob was also predictive of extended LOS for PLP patients (6.3 ± 1.3 days, p = 0.03). CONCLUSIONS: This study describes patient characteristics and complication rates of PLPs and VGPs. The NSQIP preoperative morbprob is an effective predictor of surgical complications and is better than the mFI.

[Differences in sexual development-S2k guideline update]. / Varianten der Geschlechtsentwicklung ­ Aktualisierung der S2k-Leitlinie.

BACKGROUND: Human beings with a difference in sexual development (DSD) often underwent gender reassignment surgery during early childhood. However, the medical decision was often not congruent with the gender identity that affected persons developed later on. OBJECTIVES: To represent the interests of affected persons, an interdisciplinary guideline in cooperation with support groups was written. MATERIALS AND METHODS: The revision of the first version of the guideline, published in 2016, was edited by 18 professional societies and working groups as well as 3 support groups. A literature search was performed for each of the 12 chapters. Recommendations and statements created by the working groups were voted on during four consensus conferences. RESULTS: The guideline highlights the right of self-determination of affected persons. In this context, new legal requirements are reported. Other than necessary primary diagnostics, medical procedures should be postponed. Most important is the psychological support of parents and patients. Tumor risk of the gonads and protection of fertility are analyzed and discussed in detail. CONCLUSION: The content of the guideline represents a paradigm shift in dealing with human beings with a difference of sexual development. Projects as DSD Care and Empower-DSD help to promote the practical implementation of the guideline's recommendations.

[New S2k guideline "Surgical techniques for gender incongruence"]. / Neue S2k-Leitlinie "Chirurgische Maßnahmen bei Geschlechtsinkongruenz".

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.

Prevalence of Regret in Gender-Affirming Surgery: A Systematic Review.

INTRODUCTION: Gender-affirmation surgeries are a rapidly growing set of procedures in the field of plastic surgery. This study is novel in that a thorough analysis has not been performed quantifying, identifying, and recognizing the reasons and factors associated with regret in a largely US population. METHODS: A systematic review of several databases was conducted. After compiling the articles, we extracted study characteristics. From the data set, weighted proportions were generated and analyzed. RESULTS: A total of 24 articles were included in this study, with a population size of 3662 patients. A total of 3673 procedures were conducted in the United States, 514 in European nations, 97 in Asian nations, which included only Thailand, and 19 in South American nations, which included only Brazil. The pooled prevalence of regret was 1.94%. The prevalence of transfeminine regret was 4.0% while the prevalence of transmasculine regret was 0.8%. CONCLUSIONS: Both transfeminine and transmasculine patients had significantly lower rates of regret in the United States when compared with the rest of the world. Our study largely excluded facial gender-affirming surgeries as most of its articles did not fall into our inclusion search criteria. To our knowledge, this is the most recent review performed on the topic of regret among gender-affirming surgery patients with an emphasis on a US cohort. This analysis can help shed light on better ways to enhance patient selection and surgical experience.

Direct neurotization of free nipple grafts with cadaveric nerve grafts following mastectomy for gender affirming surgery.

BACKGROUND: Free nipple grafting makes sensory recovery challenging. Permanent decreased sensation to touch and temperature in skin-grafted skin is common. Direct neurotization of the nipple-areolar complex (NAC) graft has been described. However, quantitative data regarding degree of nipple reinnervation possible is unknown. This study aims to quantify and qualify sensation recovery following nerve coaptation to reinnervate the NAC. METHODS: Patients undergoing mastectomy for gender dysphoria from 2020 to 2022 were offered nerve allograft to restore nipple sensation. A lateral intercostal nerve was selected and coapted to allograft which was embedded beneath the nipple graft. Semmes Weinstein testing was used to assess nipple sensation. Assessments were made at visits <1 year and >1 year from surgery. Filaments used represented normal sensation, minor diminished sensation, diminished sensation, loss of protective sensation, and deep pressure sensation only. RESULTS: A total of 115 patients elected for direct neurotization. Semmes Weinstein testing was limited to 46 patients representing 46 encounters and 92 nipples in the <1 year group and 24 encounters and 48 nipples in the >1 year group. Of the 92 nipples in the <1 year group, 17 (18.5%) noted return of normal sensation and 37 (40.2%) noted minor diminished or diminished sensation, indicating nerve reinnervation. There were 38 (41%) nipples with loss of protective sensation or deep sensation only. There were 48 nipples included in the >1 year group. Of the 48 nipples, 4 (8.3%) noted normal sensation and 30 (62.5%) noted minor diminished or diminished sensation, indicating nerve reinnervation. For the remaining 14 nipples, 14 (29%) noted loss of protective sensation or deep sensation only. CONCLUSION: Sensory outcomes in NAC grafts used for reconstruction in patients undergoing double incision mastectomy remain poor. Sensation restoration beyond that expected from full thickness skin grafts can be achieved in the majority of patients with nerve allograft via direct neurotization.

Gender Affirming Facial Surgery-Anatomy and Procedures for Facial Masculinization.

For some patients, feminine facial features may cause significant gender dysphoria. Multiple nonsurgical and surgical techniques exist to masculinize facial features. Nonsurgical techniques include testosterone supplementation and dermal fillers. Surgical techniques include soft tissue manipulation, synthetic implants, regenerative scaffolding, or bony reconstruction. Many techniques are derived from experience with cisgender patients, but are adapted with special considerations to differing anatomy between cisgender and transgender men and women. Currently, facial masculinization is less commonly sought than feminization, but demand is likely to increase as techniques are refined and made available.

Gender dysphoria and gender-affirming surgery: The New York state experience.

BACKGROUND: Transgender and gender nonconforming (TGNC) individuals experience incongruence between their self-identified gender versus their birth-assigned sex. In some cases, TGNC patients undergo gender-affirming surgical (GAS) procedures. Although GAS is an evolving surgical field, there is currently limited literature documenting patient characteristics and procedures. Addressing this knowledge gap, this retrospective cohort analysis described the characteristics of New York State's TGNC residents with gender dysphoria (GD) diagnosis, including patients undergoing at least one gender-affirming surgical procedure. METHODS: Using the New York Statewide Planning and Research Cooperative System (SPARCS) database from 2002 to 2018, we identified patients' first-time TCNC records and their risk characteristics. Patients who received GAS procedures were sub-classified as top-only, bottom-only, or combined top/bottom procedures and were compared with TGNC patients who did not receive GAS. RESULTS: Of 24,615 records extracted from TGNC SPARCS database, 11,427 (46.4%) were transmasculine (female-to-male) and 13,188 (53.6%) were transfeminine (male-to-female). Overall, 2.73% of transgender patients received at least one GAS procedure. Of these patients, 78.2% had masculinizing and 21.8% had feminizing surgeries. After a diagnosis of GD, the positive predictors for a GAS-based procedure included female birth sex, pediatric age (<18 years) or older age (60+ years), commercial insurance coverage, and Hispanic race. In contrast, negative GAS predictors included male birth sex and government insurance coverage (i.e., Medicare and Medicaid). CONCLUSIONS: Compared with transgender women, transgender men were more likely to receive at least one GAS procedure. Because the race, ethnicity, and payor status of TGNC patients can impact GAS treatment rates, additional research is warranted to examine post-diagnosis GAS treatment disparities among TGNC patients.

Preoperative hypocoagulative state is an independent risk factor for wound complications and infection in gender-affirming bottom surgeries.

BACKGROUND: Bottom gender affirmation surgery (GAS) involves the risks of bleeding and associated complications. Effective preoperative blood management is paramount across surgical disciplines with international normalized ratio (INR)≤1.5 advised prior to certain surgeries. This study aimed to examine the proportion of patients who were hypocoagulative before they underwent bottom GAS and assess the influence of hypocoagulability on their 30-day post-operative outcomes. METHOD: A retrospective study on female-to-male (FtM) and male-to-female (MtF) bottom GAS was performed based on American college of surgeons national surgical quality improvement program (ACS-NSQIP) database from 2005 to 2021. Patients with hypocoagulation were identified when PTT> 60 s, PT > 30 s, and/or INR> 2. Multivariable logistic regression was used to compare the 30-day perioperative outcomes between patients with hypocoagulation and controls. RESULTS: In this study, 380 patients (182 FtM, 198 MtF) with hypocoagulation and 1176 controls (886 FtM, 310 MtF) were included. Mortality and organ system complications were infrequent in both groups. Patients with hypocoagulation had higher wound complication rates (13.68% vs. 2.64%, aOR 2.858, p < 0.01), especially wound dehiscence (10.00% vs. 0.60%, aOR 4.424, p < 0.01) and organ space infection rates (2.11% vs. 0.26%, aOR 12.77, p < 0.01). Additionally, patients with hypocoagulation had higher sepsis (0.79% vs. 0.09%, aOR 15.508, p = 0.04) and readmission rates (4.74% vs. 2.47%, aOR 1.919, p = 0.03), but lower rates of discharge not to home (7.92% vs. 25.38%, aOR 0.324, p < 0.01). CONCLUSION: Preoperative hypocoagulative state is observed in approximately a quarter of the patients undergoing bottom GAS and is an independent risk factor for increased risks of 30-day wound complications and infections. Therefore, meticulous monitoring of preoperative hemostasis and implementing hemostasis control before surgery may be necessary. Thus, it may be advisable to discontinue oral anticoagulants before the surgery.

Double longitudinal myotomy in gender-affirming colovaginoplasty: an innovative surgical technique to prevent and treat neovaginal spasms.

BACKGROUND: Gender-affirming colovaginoplasty (GACv) presents excellent postoperative results. However, neovaginal spasms, reported as painful cramps, can affect the sexual life of patients. AIM: The study sought to describe an innovative surgical technique and evaluate its impact on the prevention and treatment of neovaginal spasms. METHODS: This was a single-center prospective observational study with 2 series of patients: (1) patients who underwent GACv with double myotomy (DM) for spasm prevention (series A), in which longitudinal myotomies were performed across the defunctionalized colon, transecting the taenias, and resecting 2 strips of the intestinal muscle layer of approximately 1- to 2-mm wide and tall, leaving intact colonic tissue between strips; and (2) patients who reported neovaginal spasms in whom intravaginal-DM was performed as treatment surgery (series B), in which the posterior wall of the neovagina was dissected from the rectum and transected by longitudinal myotomies, resecting 2 strips of endoluminal mucosa and submucosal muscle of approximately 1- to 2-mm wide and tall, and the colonic mucosa was subsequently closed. OUTCOMES: Patient-reported outcomes and neovaginal examination were performed following standardized protocols. RESULTS: In series A, 177 patients underwent GACv with the DM technique and were prospectively followed for a median time of 18 months (interquartile range, 13-60 months). No patients reported neovaginal spasms. In series B, 18 patients who reported neovaginal spasms after GACv were treated with intravaginal DM. After a median time of 35 months (interquartile range, 26-45 months), 83% (n = 15 of 18) reported remission of symptoms. CLINICAL IMPLICATIONS: Double longitudinal myotomy performed on the derived portion of the colon in colovaginoplasty is an easy-to-perform and safe technique that may prevent and treat postoperative neovaginal spasms. STRENGTHS AND LIMITATIONS: Our results presented certain limitations, mainly associated with a low prevalence of neovaginal spasms, which, being of personal perception, can be underdiagnosed. To the same extent, the fact that it is a monocentric experience limits the possibility of extrapolating it to other centers. Moreover, a more trained surgical team may be the cause of fewer postoperative complications. On the other hand, the fact of being a reference center for gender-affirming surgery, having our procedures protocolized, and the prospective nature of the study allowed us to obtain a certain homogeneity and granularity of the results. CONCLUSION: DM is a safe procedure and appears to be highly effective for the prevention and treatment of neovaginal spasms after GACv. Routine use of this technique does not increase the operating time or postoperative complications. Multicenter, prospective studies are required to validate our results.
