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.

BACKGROUND: Bioimpedance spectroscopy has been suggested as a useful tool for early diagnosis of breast cancer–related lymphedema (BCRL). We aimed to describe the outcomes of published studies that evaluated bioimpedance analysis as a method for prospective surveillance and early diagnosis of BCRL. METHODS: We queried the PubMed, Ovid Medline, and EMBASE databases to identify studies that evaluated use of bioimpedance spectroscopy as a diagnostic tool. We used the keywords “bioimpedance” AND (“lymphedema” OR “lymphoedema”) in the search. Only English-language studies that reported quantitative outcomes for patients with BCRL were included. RESULTS: Of 152, 235 and 116 identified articles in PubMed, Ovid Medline and EMBASE databases, only 22 were included. Use of bioimpedance analysis for prospective surveillance has been shown to prevent chronic BCRL. All the cross-sectional and retrospective studies that evaluated bioimpedance for diagnosis of BCRL reported significantly different L-Dex scores between lymphedema patients and healthy participants; in addition, bioimpedance scores were positively correlated with volume of lymphedema. CONCLUSION: Bioimpedance analysis is a potential tool with demonstrated benefits for prevention of chronic BCRL and may be an economic and great alternative for early diagnosis of BCRL.

Objetivo: Evaluar una serie de biomarcadores que permiten medir el proceso de cicatrización de las heridas e identificar los materiales que fueron utilizados para realizar dicha medición, teniendo en cuenta su incorporación en apósitos inteligentes. Método: Se realizó una revisión sistemática a partir de PubMed, Medline, CINAHL y Embase, sobre estudios que evaluaran el uso de materiales sensibles a biomarcadores. Se incluyeron estudios en inglés, sin tomar en cuenta el estado o fecha de publicación. No se incluyeron artículos de revisión ni sinopsis de conferencias. Resultados: La búsqueda mostró 296 estudios. Un investigador seleccionó 19 artículos para su inclusión. Todos los estudios fueron experimentales. Se encontraron artículos que evaluaron pH, tensión de oxígeno, temperatura, presión, ácido úrico, y glucosa. Los materiales utilizados fueron hidrogeles, fibras y tintas conductivas. Conclusión: El biomarcador más estudiado fue el pH. Los materiales que evalúan biomarcadores por medio de métodos colorimétricos podrían ser los más adecuados para su incorporación en apósitos inteligentes. Conflicto de interés: Este estudio fue respaldado, en parte, por el centro de Medicina Individualizada de Mayo Clinic, y por la Fundación de Cirugía Plástica (Plastic Surgery Foundation).

SinopsisObjetivo:El objetivo de este estudio fue presentar diferentes opciones de manejo de heridas de difícil cicatrización utilizando colgajos libres microvasculares.Método:Se llevó a cabo una revisión retrospectiva de todos los pacientes con heridas traumáticas de difícil cicatrización, a quienes se les realizó reconstrucción con colgajo libre. Se analizaron datos demográficos, etiología de la herida, diagnóstico, tratamiento previo de la herida, tipo de colgajo utilizado, dimensiones del defecto y del colgajo, vasos receptores, complicaciones, y seguimiento.Resultados:En total, 20 pacientes fueron sometidos a reconstrucciones con colgajos libres. La edad promedio fue de 39,5 años. Se realizaron 20 colgajos libres, entre ellos: 3 de piernas cruzadas, 1 de piernas cruzadas con puente vascular, 2 osteocutáneos de peroné, 6 fasciocutáneos anterolateral del muslo, 3 perforantes de la arteria toracodorsal, 3 miocutáneos dorsal ancho, y 2 fasciocutáneos de la perforante de la arteria femoral profunda. Un paciente requirió revisión de anastomosis microvascular debido a un hematoma. El resto de los pacientes no presentó intercurrencias en el postoperatorio. Respecto al tratamiento previo, 12 pacientes recibieron terapia de presión negativa, mientras que 8 tuvieron desbridamientos quirúrgicos con subsecuente aplicación de hidrogel con plata iónica.Conclusión:Las heridas de difícil cicatrización no tienen una buena respuesta al tratamiento convencional con curaciones, injertos o colgajos locales, sino que requieren la transferencia de tejidos similares a los que se han perdido. Las técnicas microvasculares pueden ser una alternativa.

Background Lymphedema treatment is an ongoing challenge. It impacts quality of life due to pain, loss of range of motion of the extremity, and repeated episodes of cellulitis. Different modalities have been used to evaluate lymphedema; some are more error-prone and some are more invasive. However, these measurements are poorly standardized, and intrarater and interrater reliabilities are difficult to achieve. This pilot study aims to assess the feasibility of ultrasound vibroelastography for assessing patients with extremity lymphedema via measuring shear wave speeds of subcutaneous tissues. Methods Patients with clinical and lymphoscintigraphic diagnosis of secondary lymphedema in the extremities without prior surgical treatment were included. A 0.1-s harmonic vibration was generated at three frequencies (100, 150, and 200 Hz) by the indenter of a handheld shaker on the skin. An ultrasound probe was used for noninvasively capturing of wave propagation in the subcutaneous tissue. Wave speeds were measured in the subcutaneous tissues of both the control and affected extremities. Results A total of 11 female patients with secondary lymphedema in the extremities were enrolled in this study. The magnitudes of the wave speeds of the region of interest in the subcutaneous tissue at lymphedema sites in the upper extremity (3.9 ± 0.17 m/s, 5.96 ± 0.67 m/s, and 7.41 ± 1.09 m/s) were statistically higher than those of the control sites (2.1 ± 0.27 m/s, 2.93 ± 0.57 m/s, and 3.56 ± 0.76 m/s) at 100, 150, and 200 Hz (P < 0.05), and at 100 and 200 Hz (P < 0.05) between lymphedema (4.33 ± 0.35 m/s, 4.17 ± 1.00 m/s, and 4.56 ± 0.37 m/s) and controls sites (2.48 ± 0.43 m/s, 2.77 ± 0.55 m/s, and 3.06 ± 0.29 m/s) in the lower extremity. Conclusions These preliminary data suggest that ultrasound vibroelastography may be useful in the evaluation of secondary lymphedema and can be a valuable tool to noninvasively track treatment progress.

Background Vascularized gastroepiploic lymph node flaps have become a popular option to treat patients with extremity lymphedema. Overall, 2 surgical approaches to harvest this flap have been described: laparoscopic and open. In this study, we analyzed complications, harvesting time, and patient satisfaction scores, comparing these 2 techniques. Methods Between 2012– and 2018, all patients with extremity lymphedema and candidates for the gastroepiploic flap harvest were included. Two groups were compared: open and laparoscopic approaches. Flap harvest time, postoperative pain, complications, return of gastrointestinal motility, time to discharge, and patient satisfaction scores were assessed. Results A total of 177 patients were included, of which 126 underwent laparoscopic harvest and 51 patients underwent open approach. Only 2 patients in the laparoscopic group had prior abdominal surgery not related to cancer treatment compared with 7 patients in the open approach (P < 0.01). Average surgical completion time for the laparoscopic versus open approach was 136 and 102 minutes, respectively (P < 0.02). Postoperative complications for the laparoscopic versus open were as follows: 1 patient developed pancreatitis and 2 developed ileus in the laparoscopic approach, whereas 3 patients developed ileus, 1 developed small bowel obstruction, 2 developed superficial site infection, and 1 developed minor wound dehiscence in the open approach. No patient required further surgical intervention. Average return of gastrointestinal function was 1 day (laparoscopic) and 2 days (open), respectively. On a pain scale, pain scores at postoperative day 1 and upon discharge were on average 3 versus 7 and 2 versus 5, respectively (P < 0.05). Lengths of hospital stay were on average 2 days in the laparoscopic group and 5 days in the open group (P < 0.001). Patient satisfaction scores based on pain and scars were significantly better in the laparoscopic group versus open group (P < 0.03). Conclusions These data support that a minimal invasive approach is ideal and efficient when resources are available. In addition, the lower complication rate and high patient satisfaction scores give promising feedback to continue offering this technique.
