Background The pulley system plays an important role in flexion mechanism. Reconstruction after trauma can be challenging. Numerous techniques have been described with several drawbacks. Herein, we describe the superficialis flap oblique technique for A4 pulley reconstruction using an animal model. Methods Forty-two fresh legs of 21 eight-week-old chickens were used to evaluate the maximum flexion angle (MFA) and force at maximum flexion (FMF) in intact and sectioned A4 pulley equivalents of the third digit after reconstruction with the transverse double loop (TDL) technique and the superficialis oblique flap (SOF) technique. Biomechanical measurements were obtained in an exclusively designed instrument. Descriptive statistics were reported, and mean differences between the reconstructive techniques were analyzed. Results Intact and severed A4 pulley equivalent average MFA were 96.50° ± 1.70° and 115.60° ± 1.50°, respectively. Average FMF were 8.16 ± 0.23 psi with the intact pulley and 6.92 ± 0.20 psi with the sectioned pulley (P < 0.001). After reconstruction with TDL and SOF techniques, the legs reached an average MFA at the distal interphalangeal joint of 98.13° ± 1.20° and 96.90° ± 1.30°, respectively. Mean MFA difference was 1.23° (P = 0.03). Force at maximum flexion was 8.12 psi and 8.10 psi for the TDL and SOF techniques (P = 0.6), respectively. Conclusions The authors believe that SOF technique for A4 pulley reconstruction can be used as first option when available, taking into account its theoretical advantages and its proven biomechanical characteristics. Long-term functional results should be assessed to translate these results into the clinical setting.

AbstractChylous ascites is the leakage of lipid‐rich lymph into the peritoneal cavity usually due to disruption of lymphatics or increased peritoneal lymphatic pressure. Various surgical options have been proposed to treat chylous ascites but most have shown suboptimal outcomes. The gastroepiploic vascularized lymph node (GE‐VLN) flap has been described previously for the treatment of lymphedema. In chylous ascites, this flap could provide an alternate drainage pathway for the intraperitoneal chylous fluid. The purpose of this report is to present another option for the microsurgical treatment of refractory chylous ascites. Herein, we report two patients with refractory chylous ascites secondary to cancer who have undergone deep inferior epigastric‐based lymphatic “cable” flap (DIE‐LCF) connected to a pedicle GE‐VLN flap. Patients were followed‐up for a minimum of 2 years. Within the first 3 months following surgery, the patient's nutritional parameters improved along with drastic reduction of ascites. At 2 years follow‐up postoperative abdominal circumference decreased significantly. None required further peritoneal paracentesis and all patients were free of chylous ascites symptoms. In conclusion, the DIE‐LCF connected to a pedicle GE‐VLN flap could be a feasible option for the microsurgical treatment of refractory chylous ascites.

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.

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.

Background:Transmasculine chest surgery is the most common surgery performed in transmasculine patients, with high overall acceptance and low postoperative complication rates. Trends have shown clear improvement in quality of life and satisfaction. However, to the best of our knowledge, overall patient satisfaction after transmasculine chest surgery and associated factors are largely unknown. The aim of this study is to estimate the overall patient satisfaction in transgender men and nonbinary population after transmasculine chest surgery and to assess associated factors.Methods:A systematic review was conducted by searching literature in several databases. Meta-analyses of prevalence with a random-effect model for overall and subgroup prevalence were performed. Meta-regression, publication bias, and sensitivity analyses were conducted.Results:A total of 1052 transmasculine patients underwent any type of transmasculine chest surgery. The pooled overall postoperative satisfaction was 92% [95% confidence interval (CI) 88–96%]. In the subgroup metanalysis, patient satisfaction after periareolar mastectomy was 93% (CI 88%–97%) and after mastectomy with or without free nipple grafting was 90% (CI 84%–95%). Patient satisfaction for studies with mean follow-up >1 year was 91% (CI 83%–97%) and for mean follow-up of 1 year or less was 93% (CI 89%–96%).Conclusions:This study shows a high level of satisfaction in transmasculine chest surgery for both techniques, which remain stable over time. Also, our results show that this procedure impacts patient satisfaction beyond chest appearance and surgical outcomes. This corroborates its broad acceptance and the improvements in the standard of care, and decision-making approach.

Background: Vaginoplasty aims to create a functional feminine vagina, sensate clitoris, and labia minora and majora with acceptable cosmesis. The upward trend in the number of transfemale vaginoplasties has impacted the number of published articles on this topic. Herein, we conducted an updated systematic review on complications and patient-reported outcomes. Methods: A update on our previous systematic review was conducted. Several databases including MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus were assessed. Random effects meta-analysis and subgroup analyses were performed. Results: After compiling the results of the update with the previous systematic review, a total of 57 studies pooling 4680 cases were included in the systematic review, and 52 studies were used in the meta-analysis. Overall pooled data including any surgical technique showed rates of 1% [95% confidence interval (CI) <0.1%–2%] of fistula, 11% (95% CI 8%–14%) of stenosis and/or strictures, 4% (95% CI 1%–9%) of tissue necrosis, and 3% (95% CI 1%–4%) of prolapse. Overall satisfaction was 91% (81%–98%). Regret rate was 2% (95% CI <1%–3%). Average neovaginal depth was 9.4 cm (7.9–10.9 cm) for the penile skin inversion and 15.3 cm (13.8–16.7 cm) for the intestinal vaginoplasty. Conclusions: Transfemale vaginoplasty is a key component of the comprehensive surgical treatment of transfemale patients with gender dysphoria. Over time, we will see an increased demand for these procedures, so adequate surgical training, clinical/surgical experience, and research outcomes are required, as we continue to strive to provide the best care possible for a population in need.

AbstractAimThis study is a comprehensive review with the purpose of collecting the most relevant data in several sections including current treatment guidelines in the paediatric population.MethodsLiterature was systematically searched in different databases. Results were limited to 2019+ and English, French and Spanish language.ResultsChildren can exhibit mild and less severe COVID‐19 disease than adults and also have asymptomatic carriage of SARS‐CoV‐2, while severe disease is more frequently noted during infancy (<1 year). SARS‐CoV‐2 binds the angiotensin‐converting enzyme 2 (ACE‐2) receptor; age‐, racial‐, and gender‐specific differences in ACE‐2 expression need to be elucidated in order to explain the differential clinical profiles between children and adults. Multisystem inflammatory syndrome in children (MIS‐C) is an important condition to recognise in children. The decision to use antiviral or immunomodulatory therapy in a child or adolescent should be individualised based on the clinical scenario. Remdesivir is the only FDA‐approved therapy available for children older than 12 years old who require hospitalisation for COVID‐19.ConclusionFurther studies are urgently required to address prevention and treatment in at‐risk and infected children, especially with underlying comorbidities. The chapter on the overall impact of COVID‐19 in children has not yet been written. Nevertheless, SARS‐CoV‐2 has now joined a long list of human pandemics, which may forever change the world's history.
