Background:The coronavirus disease 2019 (COVID-19) pandemic provoked rapid changes in clinical practice to accommodate mandated restrictions within healthcare delivery. This study reviewed patient-reported experiences and clinical outcomes after implementation of a same-day discharge protocol after mastectomy with immediate alloplastic breast reconstruction compared with our historical overnight stay protocol.Methods:This is a retrospective single-institution study of consecutive patients who underwent mastectomy and immediate alloplastic reconstruction between July 2019 and November 2020. A postoperative survey was completed by patients to evaluate satisfaction with perioperative communications, recovery, and their overall experience.Results:A total of 302 patients (100% women) underwent mastectomy and immediate alloplastic reconstruction (174 pre-COVID-19, 128 during COVID-19). During COVID-19, 71% of patients were scheduled for a same-day discharge, among which 89% were successfully discharged the same day. Compared with pre-COVID-19, there were no differences in type of surgery, operative times, pain scores, 30-day readmission, or unplanned visits (allP> 0.05) during the COVID-19 pandemic. Compared with pre-COVID-19, patients during the pandemic reported comparable satisfaction with their care experience and postoperative recovery (56% survey response rate). Patient satisfaction was also similar between those discharged the same day (n = 81) versus the next day (n = 47) during COVID-19.Conclusions:Same-day discharge is feasible, safe, and can provide similar patient-reported satisfaction and outcomes compared with traditional overnight stay. These data highlight the ability to deliver adaptable, high-quality breast cancer care, within the constraints of a global pandemic.

Background: Diversity within the healthcare workforce is essential to improve quality of care, although evaluation of diversity within surgical training remains limited. This study analyzed diversity in recruitment of residents into surgical subspecialties at a large academic medical institution and national trends. Methods: A 21-year cross-sectional study of medical school graduates accepted into all surgical subspecialty training programs was performed. The institutional cohort was divided into two groups (1997–2006, 2007–2017). Subspecialty acceptance rates were determined between 2011 and 2018. Data on candidate demographics including gender, race, ethnicity, citizenship, and origin of medical education at a single institution and nationally were extracted. Results: Two thousand found hundred seventy-two residents were included in this study. From 1997 to 2018, female acceptances increased from 21.1% to 29.7% (p < 0.01), non-White increased from 27.9% to 31.8% (p = 0.01), and international medical graduates decreased from 28.8% to 25.5% (p = 0.02). There was no significant change in accepted Hispanic and Non-US candidates. Female subspecialty rates for subspecialties increased nationally and was comparable to our cohort, except in general surgery. Hispanic subspecialty acceptance rates were less than 10% and Black/African American acceptance rates remained less than 5% across subspecialties nationally and at our institution. Conclusion: Diversity in surgical training has modestly progressed over the last two decades, but the degree of positive change has not been universal and highlights the critical need for improvement and action. Continued institution driven and collaborative strategies are essential to promote diversity in recruitment across all surgical specialties that has implications on our future workforce and surgical leadership.

Summary: The novel coronavirus disease 2019 has had a major impact on human life and livelihood. The unprecedented challenges have expanded beyond just social and work life, and have grown to impact resident education. In this article, we review the structure of plastic surgery education before the pandemic, the different online learning opportunities for self-directed learning. A summary of the range of platforms and approaches of online remote access delivery of conferences and education that emerged or expanded as a result of the crisis has been reported. This article highlighted the rapid initiatives and efforts of programs and national and international societies to support continuing medical education in conjunction with the guidelines to “shelter at home” and maintain social distancing, and possible future for expanding the reach of online academic initiatives, in addition to the role of developing virtual technologies. The coronavirus disease 2019 crisis has created an opportunity to analyze and advance online learning options to overcome the associated challenges and continue as a reliable platform even following the resolution of the social distancing requirements.

Background: Secondary lymphedema can be a lifelong and debilitating consequence of lower extremity oncologic resection and reconstruction. The goal of this study was to identify risk factors for the development of lymphedema in patients treated for thigh sarcoma. Methods: A retrospective review analyzed all patients who underwent thigh sarcoma resection and reconstruction by a plastic surgeon at the Mayo Clinic between 1997 and 2014. Patient demographics, tumor characteristics, surgical management, adjunctive therapies, and complications of patients who did and did not develop postoperative lymphedema were compared. Results: A total of 148 patients were identified. Twelve percent of patients developed lymphedema postoperatively during an average follow-up of 26 months. Risk factors for the development of lymphedema included defect location in the medial thigh ( P = 0.04), arterial resection ( P = 0.001), arterial reconstruction ( P = 0.027), and a history of cardiac disease ( P = 0.03). Twenty-two percent of patients who developed lymphedema also experienced wound dehiscence compared with 4.6% of patients without lymphedema ( P = 0.02). There were no differences in age, body mass index, smoking, history of deep venous thrombosis or venous stasis, wound dimensions, or type of reconstruction performed in patients with and without lymphedema. Conclusions: Lymphedema is common following major oncologic resection. Preexisting cardiac disease, tumor location in the medial thigh, and arterial resection and reconstruction were associated with a higher risk of postoperative lymphedema. Noninfectious wound dehiscence may be secondary to lymphedema or represent an early indicator of patients who will ultimately develop lymphedema.

Background: Foam-mediated external suction (FMES) has previously shown to improve tissue microcirculation. We hypothesized that preconditioning fasciocutaneous perforator flaps with FMES would augment perfusion and demonstrate greater capillary recruitment. Methods: Gluteal perforator flaps were designed on sixteen 400 g rats. Continuous FMES at −125 mm Hg was applied on one side (intervention) to precondition tissue for 5 days, with the contralateral side as a paired control. In group A, we assessed changes following pretreatment, after surgery, and 7 days postprocedure, and in group B, we evaluated changes during preconditioning alone. In group A (N = 8), control and intervention flaps were assessed using laser-assisted indocyanine green fluorescence angiography. In group B, flap regions were assessed using 4-dimensional computed tomographic angiography. All flaps were analyzed for microvessel density using micro–computed tomography and histological assessment using hematoxylin and eosin and CD3 immunohistochemistry. Results: Thirty-two flaps were included in this study (N = 16 intervention and matched controls). Four-dimensional computed tomographic angiography demonstrated 17% greater tissue perfusion in preconditioned flaps (mean, 78.7 HU; SD, 8.8) versus controls (mean, 67.3 HU; SD, 15.7; P < 0.01). Laser-assisted indocyanine green fluorescence angiography showed a 30% higher mean absolute intensity in preconditioned flaps versus controls (P < 0.01). Postsurgery mean absolute intensity in preconditioned flaps remained 21% higher than in controls (P = 0.03). Preconditioned flaps demonstrated a 2-fold increase in mean vessel volume of 9.1 mm3 (SD, 7) versus 4.5 mm3 (SD, 3) in controls (P = 0.04); there was a 33% higher mean area fraction of CD31 in preconditioned flaps, 3.9% (SD, 3) versus 2.9% (SD, 3) in controls (P = 0.03). Conclusion: FMES preconditioning has the potential to augment vascularity of tissue for flap harvest; however, further experimental studies are required to optimize strategies and evaluate long-term effects for clinical applications.

Abstract Background Autologous breast reconstruction (ABR) has grown in popularity due to improved aesthetic and long-term patient reported outcomes, but data regarding sensory reinnervation of autologous flaps remain limited. Traditionally, the lateral cutaneous branch of the fourth intercostal nerve has been used for flap neurotization, but the use of the anterior cutaneous branch of the intercostal nerves (ACB) offer a more optimal location to the microsurgical field when using internal mammary vessels for the microanastomosis. This study aimed to evaluate the optimum ACB recipient site level for sensory nerve coaptation in ABR. Methods Twelve hemi-chests were dissected from six fresh cadaveric females. Costal cartilages were removed and the anterior cutaneous intercostal nerve (ACB) and the lateral (subcutaneous) division of the anterior cutaneous branch (LACB) of the intercostal nerve were exposed. Anatomical measurements were recorded, and nerve samples were evaluated histologically with carbonic anhydrase staining to differentiate sensory fascicles. Assessment of fascicular diameter, axonal counts, and fascicular area were compared. Results A total of 75 nerve specimens were assessed. The ACB was identified at all levels (100%) and the subcutaneous LACB was noted consistently in the second to fourth rib space (96% cadavers), with a median length of 43, 37.5, and 37 mm, respectively. Across all rib spaces, the fascicular and axonal counts were comparable between the LACB and ACB. Nerves in the second intercostal space had a significantly larger mean fascicular area mean (112,816 ± 157,120 µm2) compared with that in the fourth (mean 26,474 ± 38,626 µm2), p = 0.03. Axonal count of sensory fascicles was the highest in the second intercostal nerves (p < 0.05). Conclusion This study provides anatomical and histological basis to determine the optimum recipient site choice for sensory coaptation in microsurgical breast reconstruction. This would aid in operative decision-making regarding the ideal recipient anterior cutaneous intercostal nerve branches for recipient site coaptation in ABR.

Background The deep inferior epigastric artery perforator (DIEP) flap is the commonest flap used for breast reconstruction after mastectomy. It is performed as a unilateral (based on one [unipedicled] or two [bipedicled] vascular pedicles) or bilateral procedure following unilateral or bilateral mastectomies. No previous studies have comprehensively analyzed analgesia requirements and hospital stay of these three forms of surgical reconstruction. Methods A 7-year retrospective cohort study (2008–2015) of a single-surgeon’s DIEP-patients was conducted. Patient-reported pain scores, patient-controlled morphine requirements and recovery times were compared using non-parametric statistics and multivariable regression. Results The study included 135 participants: unilateral unipedicled (n=84), unilateral bipedicled (n=24) and bilateral unipedicled (n=27). Univariate comparison of the three DIEP types showed a significant difference in 12-hour postoperative morphine requirements (P=0.020); bipedicled unilateral patients used significantly less morphine than unipedicled (unilateral) patients at 12 (P=0.005), 24 (P=0.020), and 48 (P=0.046) hours. Multivariable regression comparing these two groups revealed that both reconstruction type and smoking status were significant predictors for 12-hour postoperative morphine usage (P=0.038 and P=0.049, respectively), but only smoking, remained significant at 24 (P=0.010) and 48 (P=0.010) hours. Bilateral reconstruction patients’ mean hospital stay was 2 days longer than either unilateral reconstruction (P<0.001). Conclusions Although all three forms of DIEP flap breast reconstruction had similar postoperative pain measures, a novel finding of our study was that bipedicled DIEP flap harvest might be associated with lower early postoperative morphine requirements. Bilateral and bipedicled procedures in appropriate patients might therefore be undertaken without significantly increased pain/morbidity compared to unilateral unipedicled reconstructions.
