OBJECTIVE To determine the impact of gender-affirming mastectomy on depression, anxiety, and body image. BACKGROUND There are many cross-sectional and ad-hoc studies demonstrating the benefits of gender-affirming surgery. There are few prospective investigations of patient-reported outcomes in gender-affirming surgery using validated instruments. METHODS In this prospective study, patients presenting the University of Michigan for gender-affirming Mastectomy were surveyed preoperatively and six-months postoperatively. Primary outcomes were patient-reported measurements of anxiety measured by GAD-7, depression measured by PHQ-9, body image measured by BODY-Q and BIQLI, psychosocial and sexual functioning measured by BREAST-Q, and satisfaction with decision measured by BREAST-Q. Linear regression analysis was used to control for presence of complication and existing history of mental health conditions. RESULTS 70 patients completed the study. The average age of participants was 26.7. The mean PHQ-9 score preoperatively was 7.8 and postoperatively was 5.4 (p=0.001). The mean preoperative and postoperative GAD-7 scores were 7.6 and 4.6 respectively (p

BACKGROUND Although the benefits of gender-affirming surgery may be apparent to patients and providers, there remains a paucity of studies assessing the impact of these procedures. As an initial step, preoperative patient-reported outcomes using validated measures of depression, anxiety, and body image were used and compared to cisgender normative data. METHODS Patients presenting for gender-affirming mastectomy were approached and surveyed using validated instruments measuring anxiety, depression, and body image. In addition, clinical data were collected from the medical record. Results were compared to published instrument norms in the general cisgender population. RESULTS One hundred three patients completed the preoperative assessment; 70.3 percent and 66.3 percent of the cohort screened positive for mild to severe depression and anxiety, respectively. Only 25 percent and 29.8 percent of the cohort, respectively, had a previous diagnosis of depression and anxiety. The rates of depression and anxiety were significantly higher than those in cisgender normative data [mean Patient Health Questionnaire score, 2.7 (p < 0.0001); mean Generalized Anxiety Disorder Scale 7 score, 2.66 (p < 0.0001)]. Body Image Quality of Life Index and BREAST-Q scores were also significantly lower than those in cisgender normative data. CONCLUSIONS Patients seeking gender-affirming mastectomy have a significant mental health burden that appears to be underdiagnosed. They further have significant challenges with body image compared with cisgender normative data. These findings signify dramatic mental health disparities in the preoperative transgender population and the need for ongoing prospective research of gender-affirming surgery.

Introduction This article is the third in a 3-part series focused on the comprehensive treatment of gender dysphoria. Multidisciplinary gender dysphoria care may involve a combination of counseling, social gender transition, hormone therapy, and gender confirmation surgery (GCS) to maximize physical characteristics congruent with a patient’s gender identity. Nonoperative management of gender dysphoria was covered in part 1. The focus of part 2 was feminizing GCS. In part 3, surgical considerations for masculinizing GCS are summarized, including a review of different phalloplasty techniques. This installment also includes information about adjunctive procedures, therapies, and products used by transgender men and women to express their gender identity. Aim To provide an overview of both genital and nongenital masculinizing gender confirmation procedures. To review phalloplasty techniques, preoperative considerations, complications, and outcomes. To summarize ancillary services and procedures available to transgender patients to facilitate their gender presentation. Methods A review of relevant literature through May 2017 was performed via PubMed. Main Outcome Measures To summarize ancillary products and services used by transgender patients and to review surgical considerations for masculinizing genitoplasty. Results A variety of nonsurgical ancillary services exist for transgender patients to aid their transition. A variety of phalloplasty procedures have been developed for transgender men who seek genital GCS. Most surgeons prefer radial forearm phalloplasty, including the authors whose surgical technique is described. Each phalloplasty approach is associated with its own benefits, drawbacks, and complications. Conclusion A variety of ancillary services and procedures that help transgender men and women communicate their gender identity in society is available and is an important adjunct to medical or surgical treatment of gender dysphoria. Pre-operative, intra-operative, and post-operative considerations of masculinizing genital gender confirmation procedures were reviewed. Hadj-Moussa M, Agarwal S, Ohl DA, et al.

Background To optimize neovaginal dimensions, several modifications of the traditional penile inversion vaginoplasty are described. Options for neovaginal lining include skin grafts, scrotal flaps, urethral flaps, and peritoneum. Implications of these techniques on outcomes remain limited. Methods A systematic review of recent literature was performed to assess evidence on various vaginal lining options as adjunct techniques in penile inversion vaginoplasty. Study characteristics, neovaginal depth, donor-site morbidity, lubrication, and complications were analyzed in conjunction with expert opinion. Results Eight case series and one cohort study representing 1622 patients used additional skin grafts when performing penile inversion vaginoplasty. Neovaginal stenosis ranged from 1.2 to 12 percent, and neovaginal necrosis ranged from 0 to 22.8 percent. Patient satisfaction with lubrication was low in select studies. Three studies used scrotal flaps to line the posterior vaginal canal. Average neovaginal depth was 12 cm in one study, and neovaginal stenosis ranged from 0 to 6.3 percent. In one study of 24 patients, urethral flaps were used to line the neovagina. Neovaginal depth was 11 cm and complication rates were comparable to other series. Two studies used robotically assisted peritoneal flaps with or without skin grafts in 49 patients. Average neovaginal depth was approximately 14 cm, and complication rates were low. Conclusions Skin grafts, scrotal flaps, urethral flaps, and peritoneal flaps may be used to augment neovaginal canal dimensions with minimal donor-site morbidity. Further direct comparative data on complications, neovaginal depth, and lubrication are needed to assess indications in addition to advantages and disadvantages of the various lining options.

In facial reanimation via microneurovascular muscle transfer, dual-nerve reinnervation of the muscle capitalizes on the synergistic effects of spontaneous motion from cross facial nerve grafting (CFNG) and increased excursion from masseteric nerve transfer. Two-stage approaches that delay masseteric nerve transfer until the time of the muscle flap increase spontaneity by maximizing muscle reinnervation from the CFNG. While this 2-stage, dual-nerve approach has been described in adults, we present a series of pediatric patients who underwent this reconstructive technique.We retrospectively reviewed all pediatric patients who underwent 2-stage, dual-nerve reconstruction with CFNG and ipsilateral masseteric nerve transfers. Procedures were performed between 2004 and 2016 by 2 surgeons at a single centre. Degree of facial paralysis before and after surgical intervention was measured using House-Brackmann scores.Nine patients with a mean age of 8.6 (range: 5-15 years) years at time of surgery underwent 2-stage, dual-nerve reconstruction. Average time between CFNG and transfer of the free gracilis with masseteric nerve transfer was 13.3 (SD 2.4) months. Mean follow-up was 27.3 months (SD 25.7). Patients demonstrated initiation of voluntary movement on paralyzed side by 3.6 months (SD 0.6) on average, with 3 patients demonstrating spontaneous movement at 3 months.The 2-stage, dual innervation technique using CFNG and delayed ipsilateral masseteric nerve transfer with a free gracilis is a promising reconstructive option to maximize spontaneous expression in pediatric patients. Validated, objective scoring systems for excursion are needed before meaningful comparisons can be made to other reconstructive strategies.Lors de la réanimation faciale par transfert du muscle microneurovasculaire, la réinnervation de deux nerfs du muscle tire profit des effets synergétiques du mouvement spontané à partir de la greffe de nerf transfacial (GNTF) et améliore l’excursion du transfert de nerf massétérin. Une intervention en deux étapes qui reporte le transfert du nerf massétérin jusqu’à ce que le lambeau musculaire améliore la spontanéité par une maximisation de la réinnervation musculaire à partir de la GNTF. Cette intervention sur deux nerfs en deux étapes a été décrite chez les adultes, mais les chercheurs présentent les résultats de cette technique chez une série de patients d’âge pédiatrique.Les chercheurs ont procédé à l’analyse rétrospective de tous les patients pédiatriques qui avaient subi une reconstruction de deux nerfs en deux étapes par transferts de la GNTF et du nerf massétérin ipsilatéral. Deux chirurgiens d’un même centre ont effectué les interventions entre 2004 et 2016. Les chercheurs ont mesuré le degré de paralysie faciale avant et après l’intervention chirurgicale au moyen des scores de House-Brackmann.Neuf patients, d’un âge moyen de 8,6 ans (plage de cinq à 15 ans) au moment de l’opération ont subi une reconstruction de deux nerfs en deux étapes. La période moyenne entre la GNTF et le transfert du muscle gracile libre avec le transfert du nerf massétérin était de 13,3 mois (ÉT 2,4). Le suivi moyen était d’une durée de 27,3 mois (ÉT 25,7). Les patients avaient commencé à faire des mouvements volontaires du côté paralysé au bout d’une moyenne de 3,6 mois (ÉT 0,6), et trois patients faisaient des mouvements spontanés au bout de trois mois.La technique d’innervation double en deux étapes à l’aide de la GNTF et du transfert tardif du nerf massétérin ipsilatéral avec le muscle gracile libre est une méthode de reconstruction prometteuse pour maximiser l’expression spontanée chez les patients d’âge pédiatrique. Il faudra établir des systèmes objectifs de scores d’excursion avant de faire des comparaisons significatives avec d’autres stratégies de reconstruction.

There is an increased demand for gender affirmation surgery. Chest contouring, or “top” surgery, is especially important in the female-to-male (FtM) transgender population. This Continuing Medical Education (CME) article critically appraises the available literature on top surgery to allow plastic surgeons to understand current practices and determine the best surgical technique using a decision algorithm and the patient’s preoperative anatomy and characteristics. Because a single best surgical approach does not exist due to significant variance in preoperative patient anatomy, and in order to provide a useful framework for decision making, surgical approaches described are categorized as: approach 1—remote incision procedures without skin excision; approach 2—procedures with periareolar skin excision; and approach 3—mastectomy procedures with skin excision other than periareolar skin excision. Decision algorithms that help determine the most suitable surgical technique for individual patients are reviewed. Data on complication rates and patient satisfaction will improve informed consent discussions and create realistic patient expectations.

Aims Gender dysphoria is a diagnosis whereby an individual identifies as the opposite gender. The management of patients seeking female-to-male (FTM) transition includes hormonal therapy and surgical intervention, including mastectomy. The aim of this study was to characterize the immunohistological findings in resection specimens from FTM patients. Methods and results We reviewed 68 cases (67 patients, one with re-excision) of FTM breast tissue resection by collecting clinical data, reviewing breast imaging and pathology reports (gross fibrous density, specimen weight, and number of cassettes submitted), and reviewing pathology slides [number of tissue pieces submitted, number of terminal duct lobule units (TDLUs), and the presence of histological findings]. Significant histological findings were present in 51 of 68 (75.0%) cases, including one case (1.5%) of flat epithelial atypia. Fibrocystic changes were the most common finding (27/68, 39.7%), followed by gynaecomastoid change, fibrotic stage, (22/68, 32.4%), and fibroadenomatoid change (11/68, 16.2%). Fibrocystic change was associated with increased numbers of TDLUs, and gynaecomastoid change was associated with lower body mass index and decreased numbers of TDLUs. Gynaecomastoid change showed a moderate proportion of luminal epithelial cells with strong-intensity immunohistochemical staining for oestrogen receptor, progesterone receptor, and androgen receptor, and a three-layered epithelium demonstrated by the use of cytokeratin 5/6 immunohistochemistry. Conclusions We identified gynaecomastoid change at a significantly higher rate than previously reported in female patients. We support the continued gross and histological evaluation of FTM specimens in light of the identification of atypia in one case.

BACKGROUND: The BODY-Q Chest module is a patient-reported outcome (PRO) instrument that measures satisfaction with how the chest (10 items) and nipples (5 items) look. This PRO instrument was previously field tested in an international sample of people seeking treatment for gynecomastia (n = 174), weight loss (n = 224), and chest masculinization (n = 341). OBJECTIVES: The aim of this study was to examine the psychometric performance of the BODY-Q Chest module in a new chest masculinization surgery sample. METHODS: Data were collected from patients attending a private plastic surgery outpatient clinic in Canada between January 2018 and June 2019. Rasch measurement theory analysis was used to examine how the scales performed psychometrically. RESULTS: The sample provided 266 assessments (115 preoperative, 151 postoperative). All items had ordered thresholds, providing evidence that the 4 response options for each scale worked as expected. Item fit was within ±2.5 for all items, with all Bonferroni adjusted chi-square values nonsignificant. The data for the chest (χ(2)(20) = 18.72, P = 0.54) and nipples (χ (2)(10) = 12.28, P = 0.27) scales fit the requirements of the Rasch model. Reliability was high with person separation index and Cronbach’s α values of ≥0.95 for the chest and ≥0.87 for the nipple scales, respectively. More depressive symptoms on the Patient Health Questionnaire-9 and lower health-related quality of life scales were weakly correlated with worse scores on the chest and nipple scales (P < 0.001). CONCLUSIONS: The BODY-Q Chest module was shown to be scientifically sound in an independent sample of patients seeking chest masculinization surgery.

Facial feminization surgery encompasses a broad range of craniomaxillofacial surgical procedures designed to change masculine facial features into feminine features. The surgical principles of facial feminization surgery can be applied to male-to-female transsexuals and anyone desiring feminization of the face. Although the prevalence of these procedures is difficult to quantify, because of the rising prevalence of transgenderism (approximately one in 14,000 men) along with improved insurance coverage for gender-confirming surgery, surgeons versed in techniques, outcomes, and challenges of facial feminization surgery are needed. This review is designed to critically appraise the current facial feminization surgery literature.A comprehensive literature search of the Medline, PubMed, and EMBASE databases was conducted for studies published through October of 2014 with multiple search terms related to facial feminization. Data on techniques, outcomes, complications, and patient satisfaction were collected.Fifteen articles were selected and reviewed from the 24 identified, all of which were either retrospective or case series/reports. Articles covered a variety of facial feminization procedures. A total of 1121 patients underwent facial feminization surgery, with seven complications reported, although many articles did not explicitly comment on complications. Satisfaction was high, although most studies did not use validated or quantified approaches to address satisfaction.Facial feminization surgery appears to be safe and satisfactory for patients. Further studies are required to better compare different techniques to more robustly establish best practices. Prospective studies and patient-reported outcomes are needed to establish quality-of-life outcomes for patients. However, based on these studies, it appears that facial feminization surgery is highly efficacious and beneficial to patients.

Gender dysphoria, the term used in the fifth edition of the Diagnostic and Statistical Manual of Mental Disorders(DSM) to describe distress at the incongruence between one's gender and anatomy, affects approximately 0.6 percent of the population. It is estimated that there are 134,000 Armed Forces veterans in the United States with gender dysphoria. Although gender-affirming surgery is widely accepted as a medically necessary intervention for appropriately selected patients with gender dysphoria, the Veterans Health Administration (VHA) Health Benefits package and VHA Directive 2013-033 specifically prohibit gender-affirming surgery within Veterans Affairs (VA) facilities or using VA funding. This policy, which has been legally challenged after being reaffirmed in January 2017, denies medically necessary care to veterans, causing harm to individual patients and reinforcing discrimination and prejudicial treatment of a minority population. We argue that the policy is indefensible as it violates the basic ethical principles of beneficence, nonmaleficence, and justice.

Background Incisional hernias are a complication in 10% of all open abdominal operations and can result in substantial morbidity. The purpose of this study was to determine whether inhibiting abdominal muscle contraction influences incisional hernia formation during the fascial healing after laparotomy. We hypothesized that decreasing the deformation of the abdominal musculature would decrease the size or occurrence of an incisional hernia. Methods Using an established rat model for incisional hernia, a laparotomy through the linea alba was closed with 1 mid-incision, fast-absorbing suture. Three groups were compared: a sham group (sham; n = 6) received no laparotomy, and the saline hernia (SH; n = 6) and Botox hernia (BH; n = 6) groups were treated once with equal volumes of saline or botulinum toxin (Botox, Allergan) before the incomplete laparotomy closure. On postoperative day 14, the abdominal wall was examined for herniation and adhesions, and contractile forces were measured for abdominal wall muscles. Results No hernias developed in the sham rats. Rostral hernias developed in all SH and BH rats. Caudal hernias developed in all SH rats, but in only 50% of the BH rats. Rostral hernias in the BH group were 35% shorter and 43% narrower compared with those in the SH group (P Conclusion In our rat model, partial paralysis of abdominal muscles decreases the number and size of incisional hernias. These results suggest that contractions of the abdominal wall muscle play a role in the pathophysiology of the formation of incisional hernias.

Introduction For many patients with gender dysphoria, gender-confirmation surgery (GCS) helps align their physical characteristics with their gender identity and is a fundamental element of comprehensive treatment. This article is the 2nd in a 3-part series about the treatment of gender dysphoria. Non-operative management was covered in part 1. This section begins broadly by reviewing surgical eligibility criteria, benefits of GCS, and factors associated with regret for transgender men and women. Then, the scope narrows to focus on aspects of feminizing genital GCS, including a discussion of vaginoplasty techniques, complications, and sexual function outcomes. Part 3 features operative considerations for masculinizing genital GCS. Aim To summarize the World Professional Association for Transgender Health’s (WPATH) surgical eligibility criteria and describe how patients with gender dysphoria benefit from GCS, provide an overview of genital and non-genital feminizing gender-confirmation procedures, and review vaginoplasty techniques, preoperative considerations, complications, and outcomes. Methods A review of relevant literature through April 2017 was performed using PubMed. Main Outcome Measures Review of literature related to surgical eligibility criteria for GCS, benefits of GCS, and surgical considerations for feminizing genitoplasty. Results Most transgender men and women who satisfy WPATH eligibility criteria experience improved quality of life, overall happiness, and sexual function after GCS; regret is rare. Penile inversion vaginoplasty is the preferred technique for feminizing genital GCS according to most surgeons, including the authors whose surgical technique is described. Intestinal vaginoplasty is reserved for certain scenarios. After vaginoplasty most patients report overall high satisfaction with their sexual function even when complications occur, because most are minor and easily treatable. Conclusion GCS alleviates gender dysphoria for appropriately selected transgender men and women. Preoperative, intraoperative, and postoperative considerations of feminizing genital gender-confirmation procedures were reviewed. Hadj-Moussa M, Ohl DA, Kuzon WM.

Background Gender dysphoria is the experience of marked distress due to incongruence between genetically determined gender and experienced gender. Treatment of gender dysphoria should be individualized and multidisciplinary, involving a combination of psychotherapy, social gender transition, cross-sex hormone therapy, gender-affirming surgery, and/or ancillary procedures and services. The goal of all treatment modalities is to alleviate distress and affirm the patient’s experienced gender identity. This article is the first in a 3-part series focused on the diagnostic assessment and non-operative treatment of gender dysphoria. Parts 2 and 3 focus on operative aspects of gender dysphoria treatment. Aim To summarize the recommendations of the World Professional Association for Transgender Health (WPATH) and the Endocrine Society (ES), as well as review published literature regarding the non-operative treatment of gender dysphoria. Methods A review of relevant literature through January 2017 was performed via PubMed. Outcomes WPATH guidelines regarding diagnosis and non-surgical treatment of gender dysphoria, specifically regimens and risks of cross-sex hormone therapy were reviewed. Results Few physicians have experience with the diagnosis or treatment of gender dysphoria, although the number of patients seeking treatment has risen substantially in recent years. As a result, clinicians have turned to published recommendations from WPATH and ES, both of which promote high-quality, evidence-based care for patients with gender dysphoria. Successful treatment requires an individualized multidisciplinary approach. Non-operative treatment is both safe and effective for the majority of patients with gender dysphoria. Conclusions Guidelines from WPATH and ES, along with published literature pertaining to the diagnosis and non-operative treatment of gender dysphoria, were reviewed and summarized.

BACKGROUND Educational processes that encourage a career in academic plastic surgery remain unclear. The authors' study aim was to examine the impact of training institution on the pursuit of a career in academic plastic surgery. METHODS Academic plastic surgery faculty (n = 838) were identified through an Internet-based search of all 94 Accreditation Council for Graduate Medical Education-accredited residency and fellowship training programs. Academic productivity was determined by number of peer-reviewed publications and Scopus h-index. Linear and logistic regression analyses were performed to determine the correlation between attributes after adjusting for the clustering of surgeons within programs. RESULTS In the United States, 39 percent of plastic surgeons in academic practice are trained in only 11 programs, 30 percent of faculty remained at training institutions, and 39 percent were affiliated with a private practice model. Faculty from frequently represented training programs were more likely to pursue fellowship training (OR, 1.32; 95 percent CI, 1.00 to 1.75), have higher h-indices (9.0 versus 5.4; p < 0.001), and have a greater number of peer-reviewed articles (46.6 versus 24.3; p < 0.001). Higher h-indices were correlated with male sex (7.1 versus 4.7; p < 0.001), fellowship training (7.3 versus 6.1; p < 0.05), and no private practice affiliation (5.2 versus 7.8; p < 0.001). Female surgeons represented 14.1 percent of academic plastic surgeons, were younger based on the median year of board certification (2005 versus 2000; p < 0.05), and were more likely to be on the tenure track (66.9 percent versus 57.2 percent; p < 0.05) and at the assistant professor level (73.1 percent versus 43.6 percent; p < 0.05). CONCLUSION Identification of educational processes that encourage a career in academic practice may improve resident mentorship and resident interest in academic plastic surgery.

Body mass index does not allow accurate risk stratification for individuals undergoing component separation repair of ventral hernias. The authors hypothesized that tissue morphology measurements (morphomics) of preoperative computed tomography scans stratify the risk of surgical site infection in patients undergoing ventral hernia repair with a component separation technique.The authors identified 93 patients who underwent component release ventral hernia repair (2004 to 2012). The surgical technique involved release of the external oblique muscle lateral to the linea semilunaris. Using analytic morphomic techniques, the authors measured patients' morphology using routine preoperative computed tomography scans. Two-sample t test was used to evaluate the effect of morphomic and demographic factors on surgical-site infection. Separate logistic regression analyses were performed on these morphomic factors to evaluate their predictive value in assessing the risk of surgical site infection, controlling for demographic covariates.Surgical site infections were observed in 31 percent (n = 29) of the population. Subcutaneous fat area, total body area, and total body circumference had increased odds ratios for surgical site infection (p = 0.004, 0.014, and 0.012, respectively), indicating that these measures are better associated with surgical site infection than body mass index. These calculations control for demographic covariates, confirming that these morphomic parameters are predictive of surgical site infection.Specific morphomic values serve as superior predictors of surgical site infection in patients undergoing component separation technique hernia repair than currently used values such as body mass index.Risk, III.

Background:. Gender affirmation surgery (GAS) has a positive impact on the health of transgender patients; however, some centers employ body mass index (BMI) as a strict selection criterion for surgical candidacy. Several single-center studies have found no clear correlation between BMI and complication rates. We conducted a retrospective multicenter study at 2 university-based centers to test the null hypothesis: obesity is not a significant determinant of the risk of acute surgical complications in patients undergoing penile inversion vaginoplasty (PIV). Methods:. This is a retrospective chart review of all adult patients at the University of Michigan and the University of Miami undergoing gender-affirming PIV with minimum follow-up time of 3 months between 1999 and 2017. A logistic regression model of analysis is used to examine the predictive factors for surgical complications and delayed revision urethroplasty in our patient sample. Results:. One hundred and one patients met inclusion criteria for this study. The mean BMI at the time of procedure was 26.9kg/m2 (range 17.8–48.2). Seventeen patients (16.8%) had major complications and 36 patients (35.6%) had minor complications. On logistic regression analysis, none of the recorded covariates were significant predictors of delayed revision urethroplasty or major, minor, or any complications. Conclusions:. We found that obese patients can safely undergo GAS and that BMI alone should not preclude appropriately selected patients from undergoing GAS. We acknowledge that selection based on overall health and other medical comorbidities is certainly warranted for gender-affirming PIV and all other surgical procedures.

We hypothesized that select patients undergoing planned soft tissue sarcoma (STS) excision with anticipated skin and soft tissue deficits could be treated with a two stage surgical procedure which would allow some flexibility in coverage options while not significantly increasing local recurrence rate or wound complication rate.A retrospective review was undertaken in a series of consecutive patients with a minimum 2-year follow-up treated by a single orthopedic oncologist and a single reconstructive plastic surgeon who were managed with a staged approach STS excision and reconstruction.There were 73 patients identified over a ten-year period that underwent staged STS excision and soft tissue reconstruction. There were 12 (16%) initial positive margins resected to negative final margins, and a variety of coverage procedures performed. Wound complication rate was 21%. Local recurrence rate was 11%.Staged STS excision and reconstruction is an acceptable tool in the armamentarium of the orthopedic oncologist for managing major soft tissue deficits without an increase in local recurrence rates.

Evaluation of potential grafts to improve upon current strategies for abdominal wall (AW) repair in small animal models typically involves mechanical testing using methods that currently are inadequate to assess physiologically relevant parameters. This study introduces burst inflation testing as a more relevant assessment of the mechanical integrity of the AW compared to traditional tensile testing. AWs were excised from 14 healthy adult Fischer 344 rats and tested using either a custom burst inflation device or an Instron tensile testing system. Modulus outcomes from both testing methods were compared. Mechanical analyses of native AW using burst and tensile testing methods resulted in similar average tissue moduli, but with the burst test, there was significantly less variability among specimens. The burst test had greater repeatability compared to tensile testing and has the ability to test repaired AWs without compromising the integrity of the repair site, making it a useful tool for assessing graft repairs.

Summary Introduction Presentation at scientific meetings is the usual first step to communicate new research findings. However, without subsequent, peer-reviewed publication, the wider propagation and the permanent documentation of important scholarly work may be lost. Our aim was to analyze and compare the publication status of the work presented at the European Association of Plastic Surgeons' (EURAPS) and at the American Association of Plastic Surgeons' (AAPS) annual meetings. Materials and methods By using the abstract booklets from the annual meetings, all presentations given over a 10-year period (2000–2009) were analyzed. A search using PubMed and Google Scholar was performed to obtain publication status of each presentation as of 2014 (observation period: 5 years). Data were analyzed according to subspecialty. Weighted chi-square was used to examine differences in publication rates for the two societies and for English speaking vs. non-English speaking countries. Results Seventy-two percent (n = 246) of the abstracts from the AAPS were published in peer-reviewed journals. The most published subspecialty was "Craniofacial surgery" followed by "Breast surgery." Mean time to publication was 22.1 months (range -72–111 months). The most common journal for publication was Plastic and Reconstructive Surgery (PRS). Sixty-seven percent (n = 449) of the EURAPS abstracts were published in peer-reviewed journals. The most published subspecialty was "Microsurgery" followed by "Clinical studies." The mean time to publication was 17.3 months (range -67–111 months). The most common journal for publication was PRS. Differences between the two societies' publication status were not observed (p = 0.157), but EURAPS abstracts had a significantly shorter time to publication (p = 0.007). Differences between English-speaking and non-English-speaking countries were not observed (p = 0.931). Mean level of evidence for published studies from the AAPS and the EURAPS meetings was 3.5 and 3.7, respectively. Conclusion A majority of the presented abstracts from both societies have resulted in publication. After "The Society for Cardiothoracic Surgery," AAPS and EURAPS have the highest publication rates for surgical abstracts, indicating a high scientific value of these meetings.

Supplemental Digital Content is available in the text., Background: An estimated 0.6% of the U.S. population identifies as transgender and an increasing number of patients are presenting for gender-related medical and surgical services. Utilization of health care services, especially surgical services, by transgender patients is poorly understood beyond survey-based studies. In this article, our aim is 2-fold; first, we intend to demonstrate the utilization of datasets generated by insurance claims data as a means of analyzing gender-related health services, and second, we use this modality to provide basic demographic, utilization, and outcomes data about the insured transgender population. Methods: The Truven MarketScan Database, containing data from 2009 to 2015, was utilized, and a sample set was created using the Gender Identity Disorder diagnosis code. Basic demographic information and utilization of gender-affirming procedures was tabulated. Results: We identified 7,905 transgender patients, 1,047 of which underwent surgical procedures from 2009 to 2015. Our demographic results were consistent with previous survey-based studies, suggesting transgender patients are on average young adults (average age = 29.8), and geographically diverse. The most common procedure from 2009 to 2015 was mastectomy. Complications of all gender-affirming procedures was 5.8%, with the highest rate of complications occurring with phalloplasty. There was a marked year-by-year increase in utilization of surgical services. Conclusion: Transgender care and gender confirming surgery are an increasing component of health care in the United States. The data contained in existing databases can provide demographic, utilization, and outcomes data relevant to providers caring for the transgender patient population.

Objective: The purpose of this study is to measure abdominal wall myopathic histologic and mechanical changes during incisional herniation and its effect on incisional hernia repairs. Summary Background Data: Unloaded skeletal muscles undergo characteristic atrophic changes, including change in fiber type composition, decreased cross-sectional area, and pathologic fibrosis. We hypothesize that these atrophic changes decrease muscle elastic properties and may contribute to the high laparotomy wound failure rate observed following incisional hernia repair. Methods: A rat model of chronic incisional hernia formation was used. Failing midline laparotomy incisions developed into incisional hernias. Controls were uninjured and sham laparotomy (healed) groups. Internal oblique muscles were harvested for fiber typing, measurement of cross-sectional area, collagen deposition, and mechanical analysis. Mesh hernia repairs were performed on a second group of rats with chronic incisional hernias or acute anterior abdominal wall myofascial defects. Results: The hernia group developed lateral abdominal wall shortening and oblique muscle atrophy. This was associated with a change in the distribution of oblique muscle fiber types, decreased cross-sectional area, and pathologic fibrosis consistent with myopathic disuse atrophy. These muscles exhibited significant decreased extensibility and increased stiffness. The healed (sham) laparotomy group expressed an intermediate phenotype between the uninjured and hernia groups. Recurrent hernia formation was most frequent in the chronic hernia model, and hernia repairs mechanically disrupted at a lower force compared with nonherniated abdominal walls. Conclusions: The internal oblique muscles of the abdominal wall express a pattern of changes consistent with those seen in chronically unloaded skeletal muscles. The internal oblique muscles become fibrotic during herniation, reducing abdominal wall compliance and increasing the transfer of load forces to the midline wound at the time of hernia repair.

The mechanisms causing the impaired regenerative response to injury observed in skeletal muscle of old animals are unknown. Satellite cells, stem cell descendants within adult skeletal muscle, are the primary source of regenerating muscle fibers. Apoptosis may be a mechanism responsible for the depletion of satellite cells in old animals. This work tested the hypothesis that aging increases the susceptibility of satellite cells to apoptosis. Satellite cells were cultured from the extensor digitorum longus muscles of young (3-month-old), adult (9-month-old), and old (31-month-old) Brown Norway rats. Satellite cells were treated for 24 h with the pro-apoptotic agents TNF-α (20 ng/mL) and Actinomycin D (250 ng/mL). Immunostaining for activated caspases and terminal deoxynucleotydil transferase-mediated dutp nick-end labeling (TUNEL) was performed to identify apoptotic satellite cells. Quantity of the anti-apoptotic protein bcl-2 was determined by Western blot analysis. Satellite cells from old animals demonstrated significantly higher percentages of cells with activated caspases and TUNEL-positive cells, and significantly lower amounts of bcl-2 compared to young and adult animals. These data support the hypothesis that aging increases satellite cell susceptibility to apoptosis. In old muscle, apoptosis may play a causative role in the depletion of satellite cells, impairing the regenerative response to injury.

An improved understanding of load-bearing soft tissue repair suggests that the mechanism for the improved outcomes after alloplastic incisional herniorrhaphy involves more than simple tissue replacement or material strength. We test the hypothesis that postrepair abdominal wall elastic properties are most predictive of successful abdominal wall reconstruction.A rodent model of chronic incisional hernia formation was used. Midline incisional hernias were repaired primarily with suture (n = 24) or polypropylene mesh (n = 24). Rodents were sacrificed at serial postoperative time points over 60 days. Intact abdominal wall strips were cut perpendicular to the wound for tensiometric analysis. Biopsies of wound provisional matrix were obtained for biochemical analysis.Recurrent incisional hernia formation was significantly decreased in the mesh-repair group, compared with the suture-repair group (5/24 vs 14/24, P = .02). Mesh-repaired abdominal walls demonstrated significantly more elongation (P.01) and less stiffness (P.01). Toughness was equal between wounds, although the suture-repaired wounds had increased recovery of tensile strength (P.01). There were no significant differences in collagen deposition after postoperative day 7.Mesh incisional herniorrhaphy increases abdominal wall elastic properties as measured by increased elongation and reduced stiffness. Increased abdominal wall elasticity after incisional hernia repair in turn results in lower recurrence rates.

Background: Functional outcomes in breast reconstruction are important quality measures and aid in patients' decision-making process. To address the concerns of abdominal wall morbidity with transverse rectus abdominis musculocutaneous (TRAM) flap reconstructions, the authors prospectively evaluated the long-term effects of postmastectomy breast reconstruction on trunk function using objective clinical measures. Methods: Using a multicenter prospective cohort design, they recruited women undergoing first-time immediate or delayed breast reconstructions from 12 centers and 23 plastic surgeons. Trunk functional data, objectively measured with Cybex machines, for patients with an expander/implant, pedicle TRAM, and free TRAM reconstructions were evaluated preoperatively and at postoperative years 1 and 2 in 183 patients. The effects of procedure type, timing, and laterality on trunk peak torque and range of motion were analyzed using linear regression. Results: At 2 years postoperatively, procedure type, timing, and laterality did not significantly affect the range of motion for trunk flexion and extension. Peak torque for trunk flexion at year 2 was significantly decreased in patients with TRAM compared with expander/implant reconstructions (p < 0.05), with a 6 to 19 percent decrease in flexion peak torque. However, no significant difference in flexion peak torque was found between patients with free and pedicle TRAM reconstructions. Conclusions: The authors found that (1) breast cancer patients with TRAM reconstructions had a less than 20 percent long-term deficit in trunk flexion peak torque and (2) there was no significant difference in trunk function between patients receiving pedicle and free TRAM reconstructions.
