Evaluating Access and Outcomes in Gender-affirming Breast Augmentation: A Comparative Study of a County Hospital and an Academic Center.

Background: Research on the diverse patient population undergoing gender-affirming breast augmentation remains scarce. We compared patients undergoing this procedure at San Francisco General Hospital (ZSFG), a county hospital, and the University of California, San Francisco (UCSF), an academic medical center. Methods: This was a retrospective cohort study of patients who underwent primary gender-affirming breast augmentation at ZSFG (August 2019 to June 2023) and UCSF (March 2015 to June 2023). Differences in sociodemographic characteristics, surgical access, and outcomes between sites were assessed. Results: Of 195 patients, 122 patients had surgery at UCSF and 73 patients at ZSFG. ZSFG patients were more likely to be unstably housed (P < 0.001), Spanish-speaking (P = 0.001), and to have obesity (P = 0.011) and HIV (P = 0.004). Patients at ZSFG took hormones for longer before surgical consultation (P < 0.001) but had shorter referral-to-surgery intervals (P = 0.024). Patients at ZSFG more frequently underwent a subglandular approach (P = 0.003) with longer operative times (P < 0.001). Major surgical complications were uncommon (2.1%) with no differences between sites. Aesthetically, implant malposition/rotation occurred more often in patients at UCSF (P = 0.031), but revision rates were similar at both sites. Patients at UCSF had longer follow-up periods (P = 0.008). Conclusions: County hospital patients seeking gender-affirming breast augmentation have distinct sociodemographic profiles and more comorbidities than academic medical center patients. County patients might experience greater barriers that delay surgical eligibility, such as stable housing. Nevertheless, this procedure can be safely and effectively performed in both patient populations.

Gender Is a Spectrum: Evaluating Current and Novel Ways to Inquire About Gender Identity in the Health Care Setting.

PURPOSE: The use of visuals to inquire about gender in the clinical setting has been rare. We developed a survey that included a visual spectrum to assess perceptions about the most and least inclusive ways of inquiring about gender in patients with gender dysphoria. METHODS: The survey included a multiple-choice question (MCQ), free-response question, and a visual spectrum on which respondents were asked to select one box that best depicts their gender. The survey was administered to all patients diagnosed with gender dysphoria at our institution between April and June 2022. RESULTS: A total of 223 of 856 patients responded. Those with more masculine gender identities selected boxes near the visual spectrum corner of "man," whereas responses were more variable for more feminine genders. The free-response question was identified by 59% of respondents as the most inclusive. The MCQ was identified as least inclusive by 70.4%. The visual spectrum was considered the most inclusive method by the majority of patients who self-identified as woman and demiwoman/demifemale. Being asked about pronouns was extremely or very important in the health care setting for 52% of respondents, but 68.6% indicated that they are rarely or sometimes asked about their pronouns in this setting. CONCLUSIONS: The traditional MCQ format for self-identifying gender may be lacking in inclusivity and fails to represent the nuances of gender identity. Free response was considered the most inclusive way to inquire about gender among our respondents. These findings highlight the importance of formatting gender identity questionnaires to foster inclusivity for transgender patients.

The complexity of online patient education materials for wound care strategies: A readability analysis.

BACKGROUND: In the United States, over 6 million people are affected by chronic wounds. Patients often rely on the Internet for treatment information; however, these educational materials typically exceed the average eighth-grade health literacy level. This study aimed to assess the readability and language accessibility of online patient education materials on wound care strategies. METHODS: A search was conducted on Google for articles related to wound care strategies. The first 12 unique websites from each search strategy were selected for further analysis. Readability was assessed using 11 tests, with the mean scores calculated for each. RESULTS: A total of 66 articles pertaining to wound care strategies were retrieved from 43 websites. All articles had an average reading grade level of 13.5 ± 2.5 and an average reading age of 18.7 ± 2.5 years. Websites were categorized by the following sources: academic (34.9%), reagent/biologic manufacturers (27.9%), wound care (18.6%), news media organizations (14%), and other (4.7%). Flesch Reading Ease Score, graded from 0 for most difficult to 100 for least difficult, was found to be highest for academic websites (44.2, P = .01) and lowest for news media websites (24.9, P = .01). Academic websites were available in the more languages compared to all other website categories (P < .01). CONCLUSION: Online materials related to wound care strategies often exceed the National Institute of Health recommended eighth-grade reading level. This study emphasizes the need for healthcare providers to create more accessible educational materials to address the gap in health literacy and optimize patient care.

Paraspinous Muscle Flaps in Complex Pediatric Spine Surgeries: A 12-Year Single Institution Experience.

PURPOSE: The benefits of paraspinous flaps in adult complex spine surgery patients are established in the literature; however, their use in pediatric patients has not been well described. This study compares clinical outcomes with and without paraspinous muscle flap closure in pediatric patients who have undergone spine surgery. METHODS: We conducted a retrospective review of all pediatric spine surgeries at the University of California, San Francisco from 2011 to 2022. Patients were divided into 2 cohorts based on whether the plastic surgery service closed or did not close the wound with paraspinous muscle flaps. We matched patients by age, American Society of Anesthesiology classification, prior spinal surgical history, and diagnosis. Surgical outcomes were compared between the 2 cohorts. RESULTS: We identified 226 pediatric patients who underwent at least one spinal surgery, 14 of whom received paraspinous flap closure by plastic surgery. They were matched in a 1:4 ratio with controls (n = 56) that did not have plastic surgery closure. The most common indication for plastic surgery involvement was perceived complexity of disease by the spine surgeon with concern for inadequate healthy tissue coverage (78.6%), followed by infection (21.4%). Postoperative complications were similar between the two groups. The plastic surgery cohort had a higher rate of patients who were underweight (57.1% vs 14.3%, P < 0.01) and had positive preoperative wound cultures (28.6% vs 8.9%, P = 0.05), as well as a higher rate of postoperative antibiotic usage (78.6 vs 17.9%, P < 0.01). There was no difference in recorded postoperative outcomes. CONCLUSIONS: Spine surgeons requested paraspinous flap closure for patients with more complex disease, preoperative infections, history of chemotherapy, or if they were underweight. Patients with paraspinous flap coverage did not have increased postoperative complications despite their elevated risk profile. Our findings suggest that paraspinous muscle flaps should be considered in high-risk pediatric patients who undergo spine surgery.

Developing Gender-Affirming Surgery Curricula for Plastic Surgery Residency and Fellowship via Delphi Consensus.

BACKGROUND: Gender-affirming surgery (GAS) is a rapidly growing field within plastic surgery, and residents and fellows must receive appropriate training. However, there are no standardized surgical training curricula. The objective of this study was to identify core curricula within the field of GAS. METHODS: Four GAS surgeons from different academic institutions identified initial curricular statements within six categories: (1) comprehensive GAS care, (2) gender-affirming facial surgery, (3) masculinizing chest surgery, (4) feminizing breast augmentation, (5) masculinizing genital GAS, and (6) feminizing genital GAS. Expert panelists consisting of plastic surgery residency program directors and GAS surgeons were recruited for three rounds of the Delphi-consensus process. The panelists decided whether each curriculum statement was appropriate for residency, fellowship, or neither. A statement was included in the final curriculum when Cronbach α value was greater than or equal to 0.8, meaning that 80% or more of the panel agreed on inclusion. RESULTS: A total of 34 panelists (14 plastic surgery residency program directors and 20 GAS surgeons representing 28 US institutions) participated. The response rate was 85% for the first round, 94% for the second, and 100% for the third. Out of 124 initial curriculum statements, 84 reached consensus for the final GAS curricula, 51 for residency, and 31 for fellowship. CONCLUSIONS: A national consensus on core GAS curriculum for plastic surgery residency and GAS fellowship was achieved by a modified Delphi method. Implementation of this curriculum will ensure that trainees in plastic surgery are adequately prepared in the field of GAS.

The Effect of Pectoral Nerve Blocks on Opioid Use and Postoperative Pain in Masculinizing Mastectomy: A Randomized Controlled Trial.

BACKGROUND: Bilateral masculinizing mastectomy is the most common gender-affirmation operation performed. Currently, there is lack of data regarding intraoperative and postoperative pain control for this population. It is the authors' aim to study the effects of the pectoral nerve (Pecs) I and II regional nerve blocks in patients undergoing masculinizing mastectomy. METHODS: A randomized, double-blind, placebo-controlled trial was performed. Patients undergoing bilateral gender-affirmation mastectomy were randomized to receive either a Pecs block with ropivacaine or placebo injection. The patient, surgeon, and anesthesia team were blinded to the allocation. Intraoperative and postoperative opioid requirements were collected and recorded as morphine milligram equivalents (MME). Participants recorded postoperative pain scores at specific time points on the day of surgery through postoperative day 7. RESULTS: Fifty patients were enrolled between July of 2020 and February of 2022. Twenty-seven were randomized to the intervention group and 23 to the control group, with 43 patients undergoing analysis. There was no significant difference in intraoperative MME between the Pecs block group and the control group (9.8 versus 11.1; P = 0.29). In addition, there was no difference in postoperative MME between the groups (37.5 versus 40.0; P = 0.72). Postoperative pain scores were also similar between the groups at each specified time point. CONCLUSIONS: There was no significant reduction in opioid consumption or postoperative pain scores in patients undergoing bilateral gender-affirmation mastectomy who received a regional anesthetic when compared with placebo. In addition, a postoperative opioid-sparing approach may be appropriate for patients undergoing bilateral masculinizing mastectomy. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, I.

Perceptions of a virtual education platform: how plastic surgery education has progressed during the COVID-19 pandemic at one academic institution.

BACKGROUND: To continue education during the COVID-19 pandemic, we implemented a Virtual Education Platform (VEP) and Virtual Visiting Professorship (VVP) in March 2020 into our plastic surgery residency curriculum. This study investigated resident and guest speaker perceptions of the VEP since the start of the pandemic. METHODS: The VEP consists of weekly VVP lectures and usual conferences held over Zoom. In May 2020, residents and speakers completed surveys that assessed the perceptions of the VEP using a 5-point Likert scale and open-ended responses. In August 2021, residents also completed follow-up surveys. RESULTS: A total of 19 (100%) residents and 10 (100%) speakers responded to the 2020 surveys and 15 (88.2%) residents responded to the 2021 follow-up survey. Speakers represented nine academic institutions, one international. 74% of residents responded that they learned a lot or a great deal from the VVP. In 2021, 100% of residents agreed that virtual conferences should remain a core component in PRS residency education, even after social distancing requirements subside. The VVP lectures were mentioned as the most helpful lectures in both years. Easy accessibility without travel time was the most mentioned advantage of the VEP in both years, with significantly more residents citing this benefit in 2021 (p = 0.0076). The most reported disadvantage for residents was the lack of social interaction and community in both years, with significantly more residents in 2021 citing this as a disadvantage (p = 0.0307). Residents' attitudes also shifted such that significantly more residents liked and were satisfied with the VVP lectures from 2020 to 2021 (p = 0.04). CONCLUSION: Over a year into the COVID-19 pandemic, resident perceptions of a virtual education platform and virtual visiting professorship were very positive. The quick development, implementation, and high efficacy of these educational experiences underscore that learning is possible in alternative forms in unprecedented times.

Double-incision mastectomy after reduction mammaplasty for persistent gender dysphoria: a case report.

Most patients undergo just one type of gender-affirming top surgery, but some will have a double-incision mastectomy after reduction mammaplasty. We describe a 46-year-old transgender man who requested a flatter chest after undergoing reduction mammoplasty the previous year. We also provide three considerations to guide surgical decision-making in this situation.

Microfluidics-free single-cell genomics with templated emulsification.

Current single-cell RNA-sequencing approaches have limitations that stem from the microfluidic devices or fluid handling steps required for sample processing. We develop a method that does not require specialized microfluidic devices, expertise or hardware. Our approach is based on particle-templated emulsification, which allows single-cell encapsulation and barcoding of cDNA in uniform droplet emulsions with only a vortexer. Particle-templated instant partition sequencing (PIP-seq) accommodates a wide range of emulsification formats, including microwell plates and large-volume conical tubes, enabling thousands of samples or millions of cells to be processed in minutes. We demonstrate that PIP-seq produces high-purity transcriptomes in mouse-human mixing studies, is compatible with multiomics measurements and can accurately characterize cell types in human breast tissue compared to a commercial microfluidic platform. Single-cell transcriptional profiling of mixed phenotype acute leukemia using PIP-seq reveals the emergence of heterogeneity within chemotherapy-resistant cell subsets that were hidden by standard immunophenotyping. PIP-seq is a simple, flexible and scalable next-generation workflow that extends single-cell sequencing to new applications.

Morphometric Analysis of Gender-affirming Breast Augmentation.

According to cisgender respondents, the "preferred" feminine breast has a 45:55 upper-to-lower pole ratio. Preferred breast ratios have not been evaluated for transgender women undergoing breast augmentation. Therefore, this study aimed to determine the preferred breast ratio according to the transgender population and, thus, better inform surgeon planning. Methods: Patients diagnosed with gender dysphoria were sent a survey with morphed breast images of four different upper-to-lower pole ratios: 35:65, 45:55, 50:50, and 55:45. Respondents ranked the images according to aesthetic preference. Rankings were analyzed by the Condorcet method. Results: 298 survey responses were analyzed: 197 (66.1%) respondents identified as transgender women and 31 (10.4%) as transgender men. Most respondents were younger than 40 (64.8%). Eighty-one (27.2%) had undergone breast augmentation, 136 (45.6%) had not and were not considering it, and 81 (27.2%) had not but were considering it. Across all subgroups, the most preferred ratio was 45:55 (P = 0.046). Those with more masculine genders and assigned female at birth preferred the 45:55 and 50:50 ratios equally. Those in their 30's and younger preferred the 45:55 and 50:50 ratios equally. Conclusions: The 45:55 ratio, established as the most preferred morphometrics for breast augmentation by cisgender respondents, is also the most aesthetically preferred proportion among transgender patients. Interestingly, the 50:50 ratio, which projects a larger upper bust compared to the 45:55 ratio, may be equally or more appealing to younger patients and those with more masculine genders. We hope these results improve patient-physician shared decision-making and postoperative expectations.

Evaluating the Quality and Reliability of Gender-affirming Surgery Videos on YouTube and TikTok.

Background: Social media platforms have changed the way medical information is disseminated. Transgender patients may utilize social media to learn about gender-affirming surgery (GAS). Although videos on social media are readily accessible, their content is not verified or peer-reviewed. Therefore, this study aimed to evaluate the quality and reliability of YouTube and TikTok videos related to GAS. Methods: YouTube and TikTok were queried for gender-affirming top surgery, metoidioplasty, phalloplasty, breast augmentation, and vaginoplasty. Quality of video content was analyzed by the DISCERN scale. Quality scores were compared among the type of GAS, account user, and content category. Results: There were 275 YouTube videos and 55 TikTok videos. Most videos focused on masculinizing top surgery (P < 0.001). Overall, videos on masculinizing GAS had higher quality and reliability than videos on feminizing GAS (P < 0.001). Chest surgery videos were of higher quality than those on genital surgery (P ≤ 0.001). Videos on masculinizing top surgery had the highest quality, whereas vaginoplasty had the lowest quality and reliability (P < 0.001). Videos produced by health care professionals and academic institutions had the greatest quality and reliability, respectively (P < 0.0001), whereas videos produced by patients were the least reliable (P < 0.0001). Conclusions: Videos on GAS ranged from poor to good quality and reliability. Health care professionals, especially plastic surgeons, should create high-quality videos on social media to educate transgender patients. There should also be greater efforts in disseminating existing high-quality videos on social media. Resources posted on social media platforms can reach a wide audience through accessible means.

A Systematic Review and Meta-analysis of Techniques for Management of Postoperative Lymphatic Leaks After Groin Surgery.

PURPOSE: Plastic surgeons are often consulted to manage postoperative groin lymphatic leaks that may lead to serious sequelae if not promptly treated. Because there are no standardized guidelines for best treatment practices, this systematic review and meta-analysis evaluates the outcomes of multiple management modalities to ultimately guide decision making for surgeons. METHODS: Literature surrounding lymphatic leaks in the groin was reviewed from PubMED, MEDLINE, EMBASE, and the Cochrane Library from January 1, 2000, to December 1, 2020 according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The inciting procedure, postoperative lymphatic complication, used management, and days to resolution were recorded. Pairwise comparisons using the Wilcoxon rank sum test with Bonferroni continuity correction were used to determine which treatment modalities differed significantly and accounted for multiple hypothesis testing. RESULTS: A total of 1468 total studies were initially found, which narrowed to 267 unique articles after duplicates were removed. Twelve articles ultimately met the inclusion criteria and were included in the data analysis. There were 264 groin complications, of which 217 were initially treated with conservative management, 81 with a minimally invasive procedure, and 125 with surgery. More than 95% of all cases had an inciting procedure of a vascular nature.For vascular surgery-induced lymphatic leak treated by minimally invasive and surgical techniques, a significantly higher number of cases resolved compared with those treated conservatively (100% and 96.7% compared with 29.5%, respectively, P < 0.05). However, there were no significant differences in the proportion that resolved between the minimally invasive and surgical cases ( P = 0.11). Vascular cases that were only managed with surgery had significantly shorter days to resolution compared with cases that first attempted conservative management ( P < 0.001). CONCLUSIONS: Both minimally invasive and surgical options have increased odds of resolution and lower failure rates compared with conservative management alone. The odds of resolution were higher when treated with more invasive procedures compared with conservative-only management, but the mean days to resolution was longer. This meta-analysis depicts successful resolution with procedural management and supports an initial trial of minimally invasive techniques.

The Incidence of Breast Cancer After Gender-Affirming Mastectomy in Transmen.

BACKGROUND: The incidence of breast cancer in transmale patients and their continued risk after gender-affirming mastectomy (GAM) has not been well established. Plastic surgeons who offer GAM are often one of the few medical professionals sought out by this population, placing them in a unique position to not only deliver surgical care but also improve access to preventative cancer care. METHODS: We reviewed the senior author's experience with GAMs over the past 5 years for any incidence of breast cancer noted after or at time of surgery. We subsequently performed a thorough review of the literature for cases of breast cancer in transmen, to provide a comprehensive overview of screening, therapy, and postoperative surveillance practices. RESULTS: We identified 2 cases of breast cancer (ages 49 and 54 years) found on routine examination of pathology specimens after GAM at our institution. Both patients had been taking hormone therapy for the past 1 year. Pathology specimen revealed low-grade estrogen receptor-/progesterone receptor-positive ductal carcinoma in situ in 1 patient, and estrogen receptor-/progesterone receptor-positive invasive ductal carcinoma in the other. Both patients were referred to oncology for appropriate treatment, and both elected to continue their exogenous hormone therapy for personal reasons.Review of the literature demonstrated 36 other cases of documented breast cancer in transmen. Sixty-seven percent (24) were found after GAM, and of those, 50% were incidentally found on pathology specimen. At least 50% were found to be either estrogen-, progesterone-, or androgen receptor-positive cancers. At least 17% of cases documented continued use of masculinizing hormone therapy after cancer diagnosis. CONCLUSIONS: Most documented cases of breast cancer in transmen were diagnosed after gender-affirming surgery, which would suggest residual breast tissue does pose some risk for breast cancer. In addition, those diagnosed with cancer may elect to continue exogenous testosterone therapy despite potential added risks with hormone-receptor positivity. These cases highlight the need for agreement in current screening practices, surgical recommendations, and continuation of masculinizing hormone therapy.Plastic surgeons have the unique opportunity to educate these patients on appropriate breast cancer-related surveillance both before and after chest surgery.

Diagnosis and Treatment of Lymphatic Complications of the Groin Following Open Lower Extremity Revascularization with Plastic Surgery Closure.

INTRODUCTION: Lymphatic complications following vascular procedures involving the groin require prompt treatment to limit morbidity. Several treatments have been described, including conservative management, aspiration, sclerotherapy, and direct lymphatic ligation with or without a muscle flap have been described. To date, there is no data indicating which treatment results in the shortest time to recovery. We sought to address this gap by conducting a retrospective cohort study. METHODS: We reviewed all patients who developed a lymphatic complication after undergoing an open revascularization procedure in the groin between 2014 and 2020 in which plastic surgery was involved in the closure. A control group consisted of patients from the same timespan who did not develop a lymphatic complication. Demographics, comorbidities, operative details, and outcomes were compared between these groups. For cases identified with a lymphatic complication, the method of diagnosis, culture data, and treatment details were collected, and outcomes were compared for surgical management versus sclerotherapy. RESULTS: There were 27 lymphatic complications and 60 control patients. The complication group had a higher incidence of aortofemoral bypass (25.8% vs. 8.3%, P = 0.04), and a lower incidence of femoral-to-distal bypass (11.1% vs. 45.0%, P < 0.01). Daily drain output volume from postoperative days 1-5, and days 6-10, was significantly higher in the complication group than in the controls (194.0 vs. 44.0, P < 0.01; and 429.5 vs. 35.0, P < 0.01, respectively). In the lymphatic leak group, 16 patients (59.3%) had surgical treatment and six (22.2%) had sclerotherapy. Of those who had surgery, 71.4% had successful outcomes without the need for an additional intervention, whereas all of the patients analyzed who were treated with sclerotherapy had successful outcomes without further intervention. The average time to resolution was significantly shorter for surgery than for sclerotherapy (38.7 vs. 86.0 days, P = 0.03). CONCLUSIONS: Daily postoperative drain volume can assist with early diagnosis of a lymphatic leak in the groin following an open revascularization procedure. Sclerotherapy and surgery were each successful, but surgery resulted in significantly shorter times to resolution. In the appropriate candidates, surgery should be considered first line management of a lymphatic leak.

Prophylactic Muscle Flaps in Primary Vascular Procedures of the Groin.

BACKGROUND: Complications following vascular procedures involving the groin can lead to significant morbidity. Achieving stable soft tissue coverage over sites of revascularization can help mitigate complications. Prior evidence supports the use of muscle flaps in reoperative groins and in high risk patient populations to reduce postoperative complications. Data regarding the use of prophylactic muscle flap coverage of the groin is lacking. Therefore, the purpose of this study is to evaluate the effect of immediate prophylactic muscle flap coverage of vascular wounds involving the groin. METHODS: A retrospective cohort study was performed on all patients undergoing primary open vascular procedures involving the groin for occlusive, aneurysmal, or oncologic disease between 2014 and 2020 at a single institution where plastic surgery was involved in closure. Patient demographics, comorbidities, surgical details, and postoperative complications were compared between patients who had sartorius muscle flap coverage of the vascular repair versus layered closure alone. RESULTS: A total of 133 consecutive groins were included in our analysis. A sartorius flap was used in 115 groins (86.5%) and a layered closure was used in 18 (13.5%). Wound breakdown was similar between groups (25.2% sartorius vs. 38.9% layered closure, P = 0.26). However, the rate of reoperation was significantly higher in the layered closure group (50.0% vs. 12.2%, P < 0.01). Among patients who experienced wound breakdown (N = 36), a larger proportion of layered closure patients required operative intervention (71.4% vs. 20.7%, P = 0.02). Other rates of complications were not statistically different between groups. CONCLUSIONS: In patients undergoing primary open vascular procedures involving the groin, patients who underwent prophylactic sartorius muscle flap closure had lower rates of reoperation. Although incisional breakdown was similar between the groups overall, the presence of a vascularized muscle flap overlying the vascular repair was associated with reduced need for reoperation and allowed more wounds to be managed with local wound care alone. Consideration should be given to this low morbidity local muscle flap in patients undergoing vascular procedures involving the groin.

Evaluation of Dual-port versus Single-port Tissue Expanders in Postmastectomy Breast Reconstruction.

BACKGROUND: Immediate tissue expander placement in postmastectomy breast reconstruction can be complicated by seroma or infection, requiring further imaging studies or interventions. This study compares dual-port tissue expanders, with both an aspiration and expansion port, with single-port expanders in terms of postoperative complications and further interventions. METHODS: Patients with immediate tissue expander placement from March 2019 to March 2020 were reviewed. Complications included seroma, infection, hematoma, necrosis, and malposition of the expander. Further intervention included aspiration, ultrasound imaging, interventional radiology (IR) drainage, or return to operating room. RESULTS: In total, 128 dual-port expanders were compared with 125 single-port expanders. Patients with single-port expanders were younger (P = 0.022) and of lower BMI (P = 0.01). There were no significant differences in key complications between these groups. In multivariate analysis, single-port expanders had a 3.4× higher odds of postoperative ultrasound imaging when controlling for texture, placement, and age (P = 0.01). Mean time to IR drain placement in the dual-port group was approximately 30 days after placement in single port (51.1 versus 21.4 days, P = 0.013). Thirty-four percent of dual-port expanders had at least one aspiration in clinic performed by plastic surgery, versus 2% of single port that required ultrasound-guided aspiration (P < 0.001). CONCLUSIONS: There were no differences in key postoperative complications between the two expander cohorts. Dual-port expanders significantly reduced postoperative ultrasound imaging, and delayed IR drain placement. The added convenience of clinic aspirations likely reduced costs related to utilization of resources from other departments.

Rotational Thromboelastometry Derivative Fibrinogen-Platelet Ratio Predicts Thrombosis in Microsurgery.

BACKGROUND: Early detection of thrombotic events is of paramount importance for microsurgical procedures. Here, we present findings that underscore the value of rotational thromboelastometry (ROTEM) to aid in decision-making for pre- and postoperative anticoagulation, as well for patients with suspected hypercoagulability. METHODS: We prospectively collected pre- and postoperative ROTEM values on all free flap cases at the University of California, San Francisco, from 2015 to 2016. Patient age, body mass index, comorbidities, operative reports, risk factors, thrombotic complications, and outcomes were collected from electronic medical records. Two-sample t-tests were used to compare ROTEM values between cohorts. Modeling for sensitivity, specificity, and accuracy was done for threshold fibrinogen-to-platelet ratio (FPR). RESULTS: Of 52 patients who underwent free-tissue transfer, 15 had a thrombotic event either intraoperatively or postoperatively that required revision of the vascular anastomosis. Eight patients were clinically hypercoagulable preoperatively, seven of which had a thrombotic event. Several pre- and postoperative ROTEM values differed significantly between thrombotic and nonthrombotic cases. Preoperative (p = 0.027) and postoperative (p = 0.013) FPR were statistically significant when comparing the thrombotic to the nonthrombotic cohort. Threshold FPR ≥ 30 was the most sensitive and FPR ≥ 40 was the most specific. CONCLUSION: Our study affirms other studies that established ROTEM as an effective predictive tool for thrombotic events during free-tissue transfer. However, a lower threshold for FPR improves catchment of thrombotic events and flap failure with acceptable sensitivity. Our results support the routine use of ROTEM for detecting hypercoagulability in patients who would potentially benefit from intervention to prevent thrombotic complications.

Regret after Gender-affirmation Surgery: A Systematic Review and Meta-analysis of Prevalence.

BACKGROUND: There is an unknown percentage of transgender and gender non-confirming individuals who undergo gender-affirmation surgeries (GAS) that experiences regret. Regret could lead to physical and mental morbidity and questions the appropriateness of these procedures in selected patients. The aim of this study was to evaluate the prevalence of regret in transgender individuals who underwent GAS and evaluate associated factors. METHODS: A systematic review of several databases was conducted. Random-effects meta-analysis, meta-regression, and subgroup and sensitivity analyses were performed. RESULTS: A total of 27 studies, pooling 7928 transgender patients who underwent any type of GAS, were included. The pooled prevalence of regret after GAS was 1% (95% CI <1%-2%). Overall, 33% underwent transmasculine procedures and 67% transfemenine procedures. The prevalence of regret among patients undergoing transmasculine and transfemenine surgeries was <1% (IC <1%-<1%) and 1% (CI <1%-2%), respectively. A total of 77 patients regretted having had GAS. Twenty-eight had minor and 34 had major regret based on Pfäfflin's regret classification. The majority had clear regret based on Kuiper and Cohen-Kettenis classification. CONCLUSIONS: Based on this review, there is an extremely low prevalence of regret in transgender patients after GAS. We believe this study corroborates the improvements made in regard to selection criteria for GAS. However, there is high subjectivity in the assessment of regret and lack of standardized questionnaires, which highlight the importance of developing validated questionnaires in this population.

Building a Multidisciplinary Academic Surgical Gender-affirmation Program: Lessons Learned.

BACKGROUND: Every day, we see more patients present to hospitals and clinics seeking gender-affirmation care to ameliorate the symptoms of gender dysphoria. However, to provide a multidisciplinary approach, it is important to offer an integrated clinical program that provides mental health assessment, endocrine therapy, physical therapy, research, and the full spectrum of surgical services devoted to transgender patients. This article describes our experience on building a specialized, multidisciplinary, academic state-of-the-art gender-affirmation program. METHODS: Herein, we describe the main and critical components on how to build a multidisciplinary academic gender-affirmation program. We share our lessons learned from this experience and describe how to overcome some of the obstacles during the process. RESULTS: Building a multidisciplinary academic gender-affirmation program requires an invested team, as each and every member is essential for feedback, referrals, and to improve patient's experience. Institutional support is essential and by far the most important component to overcome some of the obstacles during the process. Having all team members working under the same institution provides all the critical components needed to improve outcomes and patient satisfaction. In addition, the collection of prospective data with a well-structured research team will provide information needed to improve clinical services and standardize clinical protocols, while leaving space for innovation. CONCLUSIONS: This article describes the steps and experience needed to build a multidisciplinary holistic academic gender-affirmation program. We provide our lessons learned during the process that will help guide those who intend to start an academic gender-affirmation program.
