OBJECTIVE:The objective of this study was to determine the outcomes of robotic peritoneal flap vaginoplasty. BACKGROUND:There is a lack of long-term outcomes data for gender-affirming vaginoplasty to inform patient decision-making. METHODS:A retrospective cohort of 500 consecutive patients undergoing robotic peritoneal flap vaginoplasty from 2017-2023 were reviewed. Complications requiring procedural intervention, self-reported vaginal dimensions, and orgasm were recorded at each follow up visit and analyzed as outcomes. RESULTS:487 (97%) of patients were followed to 3 months, and 425 (85%) to 1 year or greater. Twenty patients (4%) had a complication requiring procedural intervention, and 61(12%) had elective revision surgery. Median self-reported vaginal depth and width at 1 year was 14.5 cm (14.5-14.5) and 3.8 cm (3.8-3.8 cm). There were 12 patients (4%) no longer dilating using standard dilators at this pre-scheduled 1-year appointment, and at last follow-up ≥1 year, 8% were no longer dilating. Thirty-six (8%) of patients were considered anorgasmic at last follow up. Difficulty with orgasm prior to surgery was associated with lower rates of achieving orgasm after surgery and less consistent vaginal depth at 1 year, however 80% of these patients were able to orgasm after surgery. CONCLUSIONS:Clinician-observed and patient-reported outcomes for robotic gender-affirming peritoneal flap vaginoplasty were superior to those reported in the literature for penile inversion vaginoplasty. Patients who do not achieve orgasm prior to surgery are less likely to achieve orgasm and maintain vaginal depth afterwards, however the majority of these patients have improved sexual health after surgery.

PURPOSE/UNASSIGNED:High quality data regarding long-term clinical and patient-reported outcomes (PROs) of genital gender-affirming surgery (GGAS) are lacking, and transgender and non-binary (TGNB) community voices have not historically been included in research development. These factors limit the utility of current research for guiding patients, clinicians, payers, and other GGAS stakeholders in decision-making. The Transgender and Non-Binary Surgery (TRANS) Registry has been developed to meet the needs of GGAS stakeholders and address limitations of traditional GGAS research. METHODS/UNASSIGNED:Development of the TRANS Registry occurred over several developmental phases beginning in May 2019 to present. Stakeholder engagement was performed throughout these phases, including: determination of key clinical outcomes and PROs, creation and implementation of data collection tools within the electronic health record (EHR), and development of centralized registry infrastructure. RESULTS/UNASSIGNED:The TRANS Registry is a prospective observational registry of individuals seeking vaginoplasty and vulvoplasty. The EHR-enabled infrastructure allows patients and clinicians to contribute longitudinal outcomes data to the TRANS Registry. We describe our community engaged approach to designing the TRANS Registry, including lessons learned, challenges, and future directions. CONCLUSIONS/UNASSIGNED:The TRANS Registry is the first multicenter initiative to prospectively track the health of individuals seeking vaginoplasty and vulvoplasty using EHR-enabled methods, engaging TGNB community members and clinicians as partners in the process. This process may be used as a model for registry development in other emerging fields where high-quality longitudinal outcomes data are needed.

The 2 most common techniques for gender-affirming mastectomy are the double-incision free nipple graft and periareolar techniques. However, some patients are not well suited for either technique. When the nipples are high and on the pectoralis muscle, but there is marked breast tissue and skin redundancy, a double-incision free nipple graft would land the incision above the pectoral shadow, but a periareolar approach would not adequately remove the excess skin. In these patients, a nipple-preserving inferior-ellipse incision allows for appropriate chest contouring, leaving the nipple position unchanged and placing the incision in the pectoralis muscle shadow. A retrospective review identified all consecutive patients undergoing nipple-preserving inferior-ellipse mastectomy by the senior author (R.B.-L.). Indications were patients with moderate glandular tissue, skin excess, and a high nipple-areola complex (NAC) above the inferior border of the pectoralis major. Sixteen patients underwent inferior-ellipse mastectomy and were included. Mean follow-up was 203 days. Two patients (14%) required revision of the NAC. There was no partial or complete NAC loss. One patient (7%) developed postoperative seroma, which resolved with aspiration. For patients with moderate glandular tissue, excess skin in the inferior pole, and NAC position above the inferior border of the pectoralis major, the nipple-preserving inferior-ellipse mastectomy technique achieves excellent chest contour.

BACKGROUND:The established safety and efficacy of tranexamic acid (TXA) in minimizing perioperative blood loss has led to increased interest within plastic surgery. Prior studies demonstrate decreased edema, ecchymosis, and reduced rates of postoperative collections with administration of TXA, however its use has not been reported in gender-affirming mastectomy. This represents the first study to evaluate the impact of TXA on postoperative outcomes in patients undergoing gender-affirming mastectomy. METHODS:A single-center cohort study was performed analyzing all consecutive patients undergoing top surgery with the senior author between February 2017 and October 2022. Beginning in June 2021, all patients received 1000 mg intravenous TXA prior to incision and 1000 mg at the conclusion of the procedure. Patients were stratified according to intraoperative administration of TXA, with demographics, surgical characteristics, and postoperative outcomes compared between groups. RESULTS:A total of 851 patients underwent gender-affirming mastectomy. Of these, 646 cases were performed without TXA, while 205 patients received intravenous TXA intraoperatively as above. Patients who received TXA had significantly lower rates of seroma (20.5% vs. 33.0%; p<0.001), and hematoma (0.5% vs. 5.7%; p=0.002). There was no difference in rates of surgical site infection (p=0.74), and use of TXA was not associated with increased rates of venous thromboembolism (p=0.42). CONCLUSIONS:Intraoperative administration of TXA in patients undergoing top surgery may safely reduce the risk of postoperative seroma and hematoma without increased risk of thromboembolic events. Additional data collection and prospective studies are warranted to corroborate these findings.

BACKGROUND/UNASSIGNED:Sexual health is critical to overall health, yet sexual history taking is challenging. LGBTQ+ patients face additional barriers due to cis/heteronormativity from the medical system. We aimed to develop and pilot test a novel sexual history questionnaire called the Sexual Health Intake (SHI) form for patients of diverse genders and sexualities. METHODS/UNASSIGNED:The SHI comprises four pictogram-based questions about sexual contact at the mouth, anus, vaginal canal, and penis. We enrolled 100 sexually active, English-speaking adults from a gender-affirming surgery clinic and urology clinic from November 2022 to April 2023. All surveys were completed in the office. Patients also answered five feedback questions and 15 questions from the Patient-Reported Outcomes Measurement Information System Sexual Function and Satisfaction (PROMIS-SexFS) survey as a validated comparator. RESULTS/UNASSIGNED:One hundred patients aged 19-86 years representing an array of racial/ethnic groups, gender identities, and sexuality completed the study. Forms of sexual contact varied widely and included all possible combinations asked by the SHI. Feedback questions were answered favorably in domains of clinical utility, inclusiveness of identity and anatomy, and comprehensiveness of forms of sexual behavior. The SHI captured more positive responses than PROMIS-SexFS in corresponding questions about specific types of sexual activity. The SHI also asks about forms of sexual contact that are not addressed by PROMIS-SexFS, such as penis-to-clitoris. CONCLUSIONS/UNASSIGNED:SHI is an inclusive, patient-directed tool to aid sexual history taking without cisnormative or heteronormative biases. The form was well received by a diverse group of participants and can be considered for use in the clinical setting.

OBJECTIVE:To evaluate the incidence of gender-affirming phalloplasty and complications in a large population-based dataset. METHODS:Retrospective cohort study was done using the California Department of Health Care Access and Information datasets which include patient-level data from all licensed hospitals, emergency departments, and ambulatory surgery facilities in California. Adult patients 18 years or older undergoing gender-affirming phalloplasty in California from January 1, 2009 to December 31, 2019 were included. We examined phalloplasty-related complications using International Classification of Disease diagnosis and procedure codes and Current Procedural Terminology codes. Unique record linkage number identifiers were used to follow patients longitudinally. Statistical analysis included Kaplan-Meier survival analysis and Cox proportional hazards analysis. RESULTS:We identified 766 patients who underwent gender-affirming phalloplasty in 23 facilities. Of 475 patients with record linkage numbers, 253 (55.3%) had subsequent re-presentations to the inpatient, emergency department, and ambulatory surgery settings related to phalloplasty complications. Survival analysis indicated that 50% of patients re-presented by 1 year post-phalloplasty. Asian/Pacific Islander patients had lower risk of complications, and California residents had higher risk of complications. CONCLUSIONS:This population-based study confirms that gender-affirming phalloplasty has a high complication rate, and demonstrates for the first time an association with high rates of return to hospitals, emergency departments, and ambulatory centers. These findings provide additional higher-level evidence that may aid patient counseling, shared surgical decision making, and institutional and government policy.

BACKGROUND:The incidence of transgender adolescents seeking gender affirming surgery (GAS) in increasing. Surgical care of the adolescent transgender patient is associated with several unique technical, legal, and ethical factors. The authors present a review of the current literature on gender affirming surgery for individuals under the age of legal majority and propose directions for future research. METHODS:A scoping review of recent literature was performed to assess evidence on gender affirming surgery in individuals under the age of legal majority. Papers were included that examined either ethical or technical factors unique to pediatric GAS. Study characteristics and conclusions were analyzed in conjunction with expert opinion. RESULTS:Twelve papers were identified meeting inclusion criteria. Ten of these papers discussed ethical challenges in adolescent GAS, seven papers discussed legal challenges, and five papers discussed technical challenges. Ethical discussions focused on the principles of beneficence, nonmaleficence, and autonomy. Legal discussions centered on informed consent and insurance coverage. Technical discussions focused on the impact of puberty blockade on natal tissue. CONCLUSIONS:Surgical care of the adolescent transgender patient involves important ethical, legal, and technical considerations that must be addressed by the clinical team. As the population of individuals seeking GAS after puberty blockade increases, future research is needed describing functional and psychosocial outcomes in these individuals.
