Evaluation of Perioperative Versus Extended Courses of Antibiotic Prophylaxis After Immediate Implant-Based Breast Reconstruction.

BACKGROUND: Immediate implant-based breast reconstruction (IIBR) is the most commonly used method in breast reconstruction in the United States. However, postoperative surgical site infections (SSIs) can cause devastating reconstructive failure. This study evaluates the use of perioperative versus extended courses of antibiotic prophylaxis after IIBR for the prevention of SSI. METHODS: This is a single-institution retrospective study of patients who underwent IIBR between June 2018 and April 2020. Detailed demographic and clinical information was collected. Patients were divided into subgroups based on antibiotic prophylaxis regimen: group 1 consisted of patients who received 24 hours of perioperative antibiotics and group 2 consisted of patients who received ≥7 days of antibiotics. Statistical analyses were conducted using SPSSv26.0 with P ≤ 0.05 considered statistically significant. RESULTS: A total of 169 patients (285 breasts) who underwent IIBR were included. The mean age was 52.4 ± 10.2 years, and the mean body mass index (BMI) was 26.8 ± 5.7 kg/m2. Twenty-five percent of patients (25.6%) underwent nipple-sparing mastectomy, 69.1% skin-sparing mastectomy, and 5.3% total mastectomy. The implant was placed in the prepectoral, subpectoral, and dual planes in 16.7%, 19.2%, and 64.1% cases, respectively. Acellular dermal matrix was used in 78.7% of cases. A total of 42.0% of patients received 24-hour prophylaxis (group 1), and 58.0% of patients received extended prophylaxis (group 2). Twenty-five infections (14.8%) were identified, of which 9 (5.3%) resulted in reconstructive failure. In bivariate analyses, no significant difference was found between groups in rates of infection (P = 0.273), reconstructive failure (P = 0.653), and seroma (P = 0.125). There was a difference in hematoma rates between groups (P = 0.046). Interestingly, in patients who received only perioperative antibiotics, infection rates were significantly higher in those with BMI ≥ 25 (25.6% vs 7.1%, P = 0.050). There was no difference in overweight patients who received extended antibiotics (16.4% vs 7.0%, P = 0.160). CONCLUSIONS: Our data demonstrate no statistical difference in infection rates between perioperative and extended antibiotics. This suggests that the efficacies of current prophylaxis regimens are largely similar, with choice of regimen based on surgeon preference and patient-specific considerations. Infection rates in patients who received perioperative prophylaxis and were overweight were significantly higher, suggesting that BMI should be taken into consideration when choosing a prophylaxis regimen.

Surgical and Patient-Reported Outcomes of Open Perforator-Preserving Anterior Component Separation for Ventral Hernia Repair.

BACKGROUND: Abdominal wall reconstruction is challenging for surgeons and may be life altering for patients. There are scant high-quality studies on patient-reported outcomes following abdominal wall reconstruction. We assess long-term surgical and patient-reported outcomes of perforator-preserving open anterior component separation (OPP-ACS) following large ventral hernia repair. METHODS: A retrospective review of patients with large ventral hernia defects who underwent OPP-ACS performed by the authors (B.A.S., M.J.T.) was conducted between 2015 and 2019. Demographics, surgical history, operative details, outcomes, and complications were extracted. A validated questionnaire, Carolinas Comfort Scale (CCS), was used to assess postoperative quality of life. RESULTS: Twenty-two patients (12 males and 10 females) with a mean age and BMI of 60.9 ± 10 years and 28.9 ± 4.8 kg/m2, respectively, were included. Mean follow-up was 28.5 ± 16.3 months. All had prior abdominal surgery; 15 (68%) for abdominopelvic malignancy, 3 (14%) for previous failed hernia repair, and 8 (36%) had history of abdominopelvic radiation. Overall, 16 (73%) hernias were in the midline, 4 (18%) in the right lower quadrant, 1 (4.5%) in the right upper quadrant, and 1 (4.5%) in the left lower quadrant. Mean hernia defect surface area was 145 ± 112 cm2. A total of 9 patients (40.9%) underwent bilateral component separation, whereas 13 (59.1%) had unilateral. Bioprosthetic mesh was used in all patients as underlay. Mean mesh size and thickness were 545.6 ± 207.7 cm2 and 3.4 ± 0.5 mm, respectively. One patient presented with a minor wound dehiscence, and two presented with seromas not requiring aspiration/evacuation. One patient had hernia recurrence 22 months after surgery. One patient was readmitted for partial small bowel obstruction and one required wound revision. A total of 14 (65%) patients responded to the CCS questionnaire. At 12 months, mean score for all 23 items was 0.29 ± 0.21 (0.08-0.62), which corresponds to absence or minimal symptoms. CONCLUSION: The OPP-ACS is a safe surgical option for large, complex ventral hernias. Our cases showed minimal complication rate and hernia recurrence, and our patients reported significant improvement in life quality.

Disparities in Access to Postmastectomy Breast Reconstruction: Does Living in a Specific ZIP Code Determine the Patient's Reconstructive Journey?

BACKGROUND: Postmastectomy breast reconstruction (BR) has been shown to provide long-term quality of life and psychosocial benefits. Despite the policies initiated to improve access to BR, its delivery continues to be inequitable, suggesting that barriers to access have not been fully identified and/or addressed. The purpose of this study was to assess the influence of geographic location, socioeconomic status, and race in access to immediate BR (IBR). METHODS: An institutional review board-approved observational study was conducted. All patients who underwent breast cancer surgery from 2014 to 2019 were queried from our institutional Breast Cancer Registry. A geographical analysis was conducted using demographic characteristics and patient's ZIP codes. Euclidean distance from patient home ZIP code to UPMC Magee Women's Hospital was calculated, and χ2, Student t test, Mann-Whitney, and Kruskal-Wallis tests was used to evaluate differences between groups, as appropriate. Statistical significance was set at P < 0.05. RESULTS: Overall, 5835 patients underwent breast cancer surgery. A total of 56.7% underwent lumpectomy or segmental mastectomy, and 43.3% underwent modified, total, or radical mastectomy. From the latter group, 33.5% patients pursued BR at the time of mastectomy: 28.6% autologous, 48.1% implant-based, 19.4% a combination of autologous and implant-based, and 3.9% unspecified reconstruction. Rates of IBR varied among races: White or European (34.1%), Black or African American (27.7%), and other races (17.8%), P = 0.022. However, no difference was found between type of BR among races (P = 0.38). Moreover, patients who underwent IBR were significantly younger than those who did not pursue reconstruction (P < 0.0001). Patients who underwent reconstruction resided in ZIP codes that had approximately US $2000 more annual income, a higher percentage of White population (8% vs 11% non-White) and lower percentage of Black or African American population (1.8% vs 2.9%) than the patients who did not undergo reconstruction. CONCLUSIONS: While the use of postmastectomy BR has been steadily rising in the United States, racial and socioeconomic status disparities persist. Further efforts are needed to reduce this gap and expand the benefits of IBR to the entire population without distinction.

Characterising and managing paediatric SARSCoV-2 infection: Learning about the virus in a global classroom.

AIM: This 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. METHODS: Literature was systematically searched in different databases. Results were limited to 2019+ and English, French and Spanish language. RESULTS: Children 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. CONCLUSION: Further 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.

Independent or Integrated Plastic Surgery Residency Pathways: Trends in Representation in Academic Plastic Surgery in the United States.

INTRODUCTION: The training pathway for plastic surgery has evolved in recent years with the adoption and rise in popularity of the integrated model. Studies have demonstrated that there may be differences between integrated graduates and independent graduates, specifically in career choices and type of practice. This study seeks to understand if there are differences in representation at academic and leadership positions between graduates of the 2 pathways. METHODS: A cross-sectional study was conducted in June of 2018 to assess integrated and independent pathway graduate's representation in academic plastic surgery in the United States. Factors examined were career qualifications, academic productivity, faculty positions, and influence of pathway on career advancement. RESULTS: A total of 924 academic plastic surgeons were analyzed, 203 (22.0%) of whom were integrated graduates and 721 (78.0%) of whom were independent graduates. Independent graduates had greater National Institutes of Health funding (integrated, $40,802; independent, $257,428; P = 0.0043), higher h-index (integrated, 7.0; independent, 10.0; P < 0.001), and higher publication number (integrated, 17; independent, 25; P = 0.0011). Integrated graduates were more likely to be assistant professors (integrated, 70%; independent, 40.7%; P < 0.001) and required a shorter postresidency time to reach all positions examined compared with independent graduates. CONCLUSIONS: Residency training pathway influences academic plastic surgeons in research output, qualifications, and academic positions. This is likely due to the relatively new nature of the integrated program compared with the independent, as well as the shorter length of training for integrated graduates. However, trends are moving toward integrated graduates showing increased interest and productivity in academic medicine.

A4 Pulley Reconstruction Using the Superficialis Oblique Flap and the Transverse Double Loop Techniques: A Biomechanical Evaluation Using a Chicken Model.

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.

The deep inferior epigastric lymphatic cable flap connected to gastroepiploic lymph node flap for treatment of refractory chylous ascites: Report of two cases.

Chylous 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.

Gastroepiploic Lymph Node Flap Harvest for Patients With Lymphedema: Minimally Invasive Versus Open Approach.

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.

Ultrasound Vibroelastography for Evaluation of Secondary Extremity Lymphedema: A Clinical Pilot Study.

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.

Comparisons in long-term clinical outcomes among patients with upper or lower extremity lymphedema treated with diverse vascularized lymph node transfer.

BACKGROUND: Vascularized lymph node transfer (VLNT) is an emerging surgical treatment for lymphedema. However, literature-comparing outcomes of upper limb lymphedema (ULL) and lower limb lymphedema (LLL) is limited. Hence, the aim of this study is to compare the long-term clinical outcomes on ULL versus LLL in patients treated with VLNT. METHODS: A retrospective study retrieving data from patients with International Society of Lymphology (ISL) stages II-III who underwent different VLNTs from July 2010 to July 2016 in our institution was performed. Demographics preoperatively, and clinical data (limb circumference, infectious episodes, lymphoscintigraphic studies) preoperatively and postoperatively were recorded. Clinical outcomes by extremity were also analyzed. RESULTS: A total of 83 patients with lymphedema (ULL: n = 30, LLL: n = 53) were included. Mean follow-up time was 32.8 months (range 24-49 months). Mean circumference reduction was higher in patients with ULL compared to with LLL (28.6 ± 8.6 vs. 22.3 ± 10.1, p < .001), and for patients with secondary lymphedema (24.8 ± 9.6, p < .001) than for patients with primary lymphedema (18.9 ± 14, p > .05). Infectious episodes per year preoperative and postoperative showed that LLL patients had higher reduction on infection rate compared with ULL patients (2.4 ± 1.1 vs. 1.9 ± 1.2, p < .001). CONCLUSION: VLNT is a promising surgical treatment option for patients with lymphedema. This study suggests that VLNT may have a more beneficial outcome in patients with ULL and with secondary lymphedema.

Manejo de heridas traumáticas de difícil cicatrización con colgajos microvasculares.

OBJECTIVE: Present different flap alternatives when performing microvascular free-flap reconstruction in acute hard-to-heal wounds. METHOD: A retrospective review of patients whose acute hard-to-heal wounds were treated with microvascular free-flap reconstruction. Data on demographics, wound aetiology, diagnostic, previous treatment, free-flap type, free-flap size, complications and follow up were analysed. RESULTS: A total of 20 patients received microvascular free-flap reconstruction. The median age was 39.5 years. Twenty free-flap reconstructions were performed. These included: 3 cross-leg free flap, 1 cross-leg vascular cable bridge flap, 2 fibula osteocutaneous flap, 6 anterolateral thigh (ALT) flap, 3 thoracodorsal artery perforator (TDAP) flap, 3 fasciomyocutaneous flap, and 2 femoral artery fasciocutaneous flap. A patient required microvascular anastomosis due to hematoma; the rest did not present complications during their postoperative. Previous treatment included negative pressure wound therapy (12 patients) and surgical debridement with silver hydrogel dressings (8 patients). CONCLUSION: Hard-to-heal wounds can be unresponsive to traditional wound healing practices or local flaps. They often require free-flap reconstruction, using tissues similar to those compromised. Microvascular techniques can be an effective alternative.

OBJETIVO: 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.

The Nipple Split Sharing vs. Conventional Nipple Graft Technique in Chest Wall Masculinization Surgery: Can We Improve Patient Satisfaction and Aesthetic Outcomes?

BACKGROUND: Double incision mastectomy with free nipple grafts (DIFNG) offers more flexible nipple-areola complex (NAC) resizing and repositioning in transmale and gender non-conforming individuals. The cis-male NAC has a smaller diameter, oval shape and lateral position. If nipple grafts are performed without having these considerations, aesthetics can be dissatisfying. We aim to describe the nipple split sharing technique during chest wall masculinization surgery comparing surgical, patient-reported outcomes (PRO) and aesthetic results with the conventional technique. METHODS: This was a retrospective review of transmale patients who underwent DIFNG from January 2017 to January 2019. The cohort was divided into two groups: conventional and the splitting technique. Demographics, intraoperative and postoperative outcomes were recorded. In addition, PRO using Body-Q scale and aesthetic results using a Likert-based scale were analyzed. RESULTS: Thirty-four patients (68 breasts) underwent DIFNG. A total of 32 breasts underwent the split nipple reconstruction approach, whereas 36 underwent conventional technique. Median patient age and BMI in the nipple sharing and conventional technique groups were 27 years and 35.4 kg/m2, and 24 years and 32.2 kg/m2, respectively. Differences on postoperative complications were not statistically significant. Patient satisfaction on nipples' module was 90.7% vs. 58.1% in the nipple sharing vs. conventional technique, respectively (p < 0.05). The nipple's masculine aspect, size, contour, position and scars were aesthetically superior to the split approach (p < 0.05). CONCLUSION: Double incision mastectomy with nipple split sharing technique has good aesthetic outcomes, a low complication rate and high patient satisfaction. It is a great surgical alternative to improve aesthetics in chest wall masculinization surgery. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Robotic-Assisted DIEP Flap Harvest for Autologous Breast Reconstruction: A Comparative Feasibility Study on a Cadaveric Model.

BACKGROUND: The deep inferior epigastric perforator (DIEP) flap is the most common perforator flap for microsurgical breast reconstruction. Contrary to the conventional open approach, robotic-assisted DIEP flap harvest intends to preserve ARS integrity, thereby reducing the morbidity. We assessed the feasibility and compared performance outcomes of a robotic, cadaveric training model for DIEP flap harvest using two approaches: transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP). METHODS: A robotics system (da Vinci Xi) was applied in conjunction with a cadaveric training model. Ports were placed in the abdominal wall to triangulate each DIEP flap. Surgical time and technical characteristics were recorded. Values were analyzed and compared. RESULTS: Eight female cadavers (16 hemi-DIEP flaps) were dissected: 50% TAPP and 50% TEP approaches. Mean harvest time was 56 minutes (range: 48-74 minutes) and 65 minutes (range: 60-83 minutes) for TAPP versus TEP groups, respectively (p < 0.05). Mean pedicle dissection time was 36 minutes (range: 25-40 minutes) and 39 minutes (range: 30-42 minutes) for TAPP versus TEP groups, respectively (p > 0.05). Intra-abdominal contents were manipulated twice on average in the TAPP group versus 0 times in the TEP group (p < 0.05). One TAPP case had an injury to the bowel, and one TEP case was converted to conventional open due to pneumoperitoneum. CONCLUSION: Robotic-assisted DIEP flap harvest represents a technological enhancement for advanced regenerative plastic surgery. Our model demonstrated both TAPP and TEP are feasible, with TEP less invasive, preserving the posterior rectus sheath, and decreasing complication risks. However, there is a steeper and longer learning curve for TEP.

Practical management of hypertrophic scarring: the mayo clinic experience.

Hypertrophic scarring is a potential consequence of wound healing that causes functional and aesthetic disability. Common treatments include intralesional pharmacotherapy (e.g., triamcinolone), surgical excision, and energy-based laser devices. While numerous treatment methods have been described for hypertrophic scarring, an optimal treatment strategy has yet to be established given variability in clinical presentation. This study aims to identify patient- and provider-preferred treatment patterns. This is a single-center, retrospective study of adult patients that developed post-surgical hypertrophic scarring between 2007 and 2017. Specifically, trends in procedural management for hypertrophic scarring among this cohort were examined. A total of 442 procedures (intralesional steroid injection, surgical excision, laser-based treatment) were identified in 218 patients with a clinical diagnosis of hypertrophic scarring. Approximately 73% were female; 87% were Caucasian. The median age at first procedure was 45.6 years (SD = 17.4). The most frequent anatomical locations for procedures were the trunk (n = 242; 54.8%), followed by head/neck (n = 86; 19.5%), upper extremities (n = 67; 15.2%), and lower extremities (n = 45; 10.2%). Procedural therapies included intralesional steroid injection (n = 221; 50%), surgical excision (n = 112; 25.3%) and laser (fractional non-ablative laser vs. pulsed dye laser; n = 109; 24.5%). Treatment modality varied by stage of treatment, scar anatomical location, and scar size. This single-center series of patients with hypertrophic scarring highlights a patient-centered management approach and offers clinical guidelines for provider-patient shared decision making.

Lymphatic Mapping with Contrast-enhanced Ultrasound for Lymphaticovenous Anastomosis Surgery: How We Do It.

Lymphaticovenous anastomosis (LVA) surgery is an effective surgery for the treatment of lymphedema in the extremities. Indocyanine green lymphography is the reference standard for visualizing lymphatics for LVA surgery, but it has several limitations; most notably, superficial dermal congestion can mask deeper lymphatic vessels. To overcome the limitations, we add contrast-enhanced ultrasound (CEUS) lymphography. We have previously reported that CEUS lymphography can identify lymphatic vessels for LVA surgery that indocyanine green lymphography does not. Here, we describe how we perform CEUS lymphography, including workflow, technique, and documentation. Before informed consent, the patient must be screened for possible adverse reactions to microbubbles. The procedure involves multiple intradermal injections of the microbubble agent at various sites along the extremity. After each injection, imaging for microbubble uptake by lymphatic vessels is performed using an ultrasound scanner with contrast-specific software. We use sulfur hexafluoride lipid-type A microspheres (Lumason/SonoVue; Bracco Suisse SA), but we are investigating the performance of other Food & Drug Administration-approved microbubble agents for CEUS lymphography. Having a systematic approach to marking the skin can mitigate the hindrance of marking over ultrasound coupling gel. Another benefit of CEUS lymphography is the rapid identification of neighboring veins compatible in size and location for anastomosis. We hold regular scheduled multidisciplinary meetings for coordination of care, discussion of outcomes, quality assurance, and ongoing innovation.

Who Cares about Diversity? Trends in Gender and Racial Authorship and Publications in Plastic Surgery over Time.

The literature in scientific journals represents current standards for plastic surgery (PS) and new observations contributed by leaders in the field. Observations of these trends over time define our progress and document our ever-changing specialty. This study aims to assess the racial/ethnic and gender makeup of authors who have published on the topic of diversity in PS, and to define trends over time, as well as geographic and journal representation of these publications. Methods: Existing published literature was queried through PubMed with the search terms "plastic surgery" AND "diversity" from 2008 to 2021. The race/ethnicity and gender of collated authors were adjudicated using NamSor software. Trends over time regarding quantity and topics covered, as well as gender and race of authors of these publications, were identified. Results: A total of 208 papers were identified with our search strategy; 74 met inclusion criteria, representing 398 authors. White' non-Hispanic authors represented the majority of first authors (45%) and the majority of senior authors (54%). Black/African American authors comprised 18% first authors and 19% senior authors. Male authorship predominated, with 58% of first authorship and 64% of senior authorship. Conclusions: Publications on the topic of diversity have increased in recent years. Trends show a significant shift in authorship, with prevalence of white male contributions rising. Women constitute most authors on the topic of gender diversity. These findings provide important insight into who cares about diversity within our specialty and who shapes its future.

Breast Resection Weight Prediction and Insurance Reimbursement in Reduction Mammaplasty: Which Scale Is Reliable?

BACKGROUND: Many insurance companies in the United States rely on the Schnur sliding scale to predict resection weights to determine medical necessity for breast reduction surgery. Accurate methods to predict resection weights are needed to avoid insurance denials. The authors compared the accuracy of formulas such as the Schnur, Appel, Descamps, and Galveston scales in predicting resection weights, and assessed whether they influence insurance coverage decision. METHODS: A retrospective review of bilateral reduction mammaplasty procedures from June of 2017 to June of 2019 was performed at the Mayo Clinic, Rochester. Oncoplastic reduction operations were excluded. The accuracy of each formula-based estimate was evaluated with linear regression analysis. RESULTS: One hundred fifty-four patients (308 breasts) were reviewed. The Schnur scale had low correlation with actual resection weight ( r2 = 0.381; b1 = 1.153; p < 0.001). The Appel scale was the most accurate ( r2 = 0.642; b1 = 1.01; p < 0.001), followed by the Descamps ( r2 = 0.572, b1 = 0.934, p < 0.001) and Galveston ( r2 = 0.672; b 1 = 0.654; p < 0.001) scales. The Appel, Descamps, and Galveston scales were more accurate for resection weights of 500 g or greater, body mass index greater than 30 kg/m², and patients younger than 50 years. For resection weights of 500 g or greater, the median difference between the estimated and actual resection weight for the Schnur, Appel, Descamps, and Galveston scales was -211.4 ± 272.3, -17.5 ± 272.3, -9.6 ± 229.5, and -99.2 ± 238.5 g, respectively. No scale was accurate for resection weights less than 500 g. Insurance reimbursement was denied in 15.56 percent of patients; of these, 23 percent had resection weights less than 500 g. The Schnur scale overestimated the resection weights in 28.9 percent of patients. CONCLUSIONS: The Schnur scale is a poor predictor of breast resection weight. The Appel scale is the most accurate estimator, especially in the young and obese population with larger resections. CLINICAL QUESTION/LEVEL OF EVIDENCE: Diagnostic, I.

Immediate Breast Reconstruction Using the Goldilocks Procedure: A Balance between More Surgery and Patient Satisfaction.

BACKGROUND: Since its first description in 2012, the Goldilocks procedure has become an option for immediate breast reconstruction, particularly for obese patients who are poor candidates for traditional implant or autologous reconstruction. In this work, the authors performed a longitudinal study of patients who underwent mastectomy with Goldilocks reconstruction to assess the incidence of additional surgical procedures, and to assess surgical outcomes and patient satisfaction. METHODS: A retrospective review of patients who underwent mastectomy with the Goldilocks procedure only at Mayo Clinic Rochester between January of 2012 and September of 2019 was performed. Demographics, complications, additional breast procedures performed to attain the final results, and patient-reported outcomes using the BREAST-Q were recorded. Univariate and multivariable analyses were performed to identify statistical associations and risk factors. RESULTS: Sixty-three patients (108 breasts) were included. Mean age was 57.8 years. Mean body mass index was 37.6 kg/m2. Median follow-up time after the mastectomy with the Goldilocks procedure was 15 months. The major complication rate within the first 30 days was 9.3 percent. Forty-four breasts (40.7 percent) underwent additional surgery. Dyslipidemia was significantly associated with an increased risk of additional surgery (adjusted hazard ratio, 2.00; p = 0.045). Scores in the four BREAST-Q domains were not statistically different between patients who had additional procedures and those who did not. CONCLUSIONS: Based on the results, the authors recommend a thorough preoperative discussion with patients who are candidates for the Goldilocks procedure to explore all options for reconstruction and their expectations, because it is crucial to reduce the necessity for additional operations in this high-risk population.
