Efficacy of PECS block in addition to multimodal analgesia for postoperative pain management in patients undergoing outpatient elective breast surgery: A retrospective study.

Background: Pectoralis nerve blocks (PECS) have been shown in numerous studies to be a safe and effective method to treat postoperative pain and reduce postoperative opioid consumption after breast surgery. However, there are few publications evaluating the PECS block effectiveness in conjunction with multimodal analgesia (MMA) in outpatient breast surgery. This retrospective study aims to evaluate the efficacy of PECS's blocks on perioperative pain management and opioid consumption. Methods: We conducted a retrospective study to assess the efficacy of preoperative PECS block in addition to preoperative MMA (oral acetaminophen and/or gabapentin) in reducing opioid consumption in adult female subjects undergoing outpatient elective breast surgery between 2015 and 2020. A total of 228 subjects were included in the study and divided in two groups: PECS block group (received PECS block + MMA) and control Group (received only MMA). The primary outcome was to compare postoperative opioid consumption between both groups. The secondary outcome was intergroup comparisons of the following: postoperative nausea and vomiting (PONV), incidence of rescue antiemetic medication, PACU non-opioid analgesic medication required, length of PACU stay and the incidence of 30-day postoperative complications between both groups. Results: Two hundred and twenty-eight subjects (n = 228) were included in the study. A total of 174 subjects were allocated in the control group and 54 subjects were allocated in the PECS block group. Breast reduction and mastectomy/lumpectomy surgeries were the most commonly performed procedures (48% and 28%, respectively). The total amount of perioperative (intraoperative and PACU) MME was 27 [19, 38] in the control group and 28.5 [22, 38] in the PECS groups (p = 0.21). PACU opioid consumption was 14.3 [7, 24.5] MME for the control group and 17 [8, 23] MME (p = 0.732) for the PECS group. Lastly, the mean overall incidence of postsurgical complications at 30 days was 3% (N = 5), being wound infection, the only complication observed in the PECS groups (N = 2), and hematoma (N = 2) and wound dehiscence (N = 1) in the control group. Conclusion: PECS block combined with MMA may not reduce intraoperative and/or PACU opioid consumption in patients undergoing outpatient elective breast surgery.

The burden of perioperative hypertension/hypotension: A systematic review.

STUDY OBJECTIVE: Our goal is to review the outcomes of acute hypertensive/hypotensive episodes from articles published in the past 10 years that assessed the short- and long-term impact of acute hypertensive/hypotensive episodes in the perioperative setting. METHODS: We conducted a systematic peer review based upon PROSPERO and Cochrane Handbook protocols. The following study characteristics were collected: study type, author, year, population, sample size, their definition of acute hypertension, hypotension or other measures, and outcomes (probabilities, odds ratio, hazard ratio, and relative risk) and the p-values; and they were classified according to the type of surgery (cardiac and non-cardiac). RESULTS: A total of 3,680 articles were identified, and 66 articles fulfilled the criteria for data extraction. For the perioperative setting, the number of articles varies by outcome: 20 mortality, 16 renal outcomes, 6 stroke, 7 delirium and 34 other outcomes. Hypotension was reported to be associated with mortality (OR 1.02-20.826) as well as changes from the patient's baseline blood pressure (BP) (OR 1.02-1.36); hypotension also had a role in the development of acute kidney injury (AKI) (OR 1.03-14.11). Postsurgical delirium was found in relation with BP lability (OR 1.018-1.038) and intra- and postsurgical hypotension (OR 1.05-1.22), and hypertension (OR 1.44-2.34). Increased OR (37.67) of intracranial hemorrhage was associated to postsurgical systolic BP >130 mmHg. There was a wide range of additional diverse outcomes related to hypo-, hypertension and BP lability. CONCLUSIONS: The perioperative management of BP influences short- and long-term effects of surgical procedures in cardiac and non-cardiac interventions; these findings support the burden of BP fluctuations in this setting.

Spirituality and Wellness in Plastic Surgery: A Survey of ASPS Members.

Spirituality is an important, yet often overlooked, component of personal well-being. The purpose of this study was to assess whether spirituality plays an important role in the well-being of US plastic surgeons and residents, and whether spirituality is viewed as an important component of patient care. METHODS: An anonymous and voluntary email survey was distributed to 3375 members of ASPS during the months of April through June of 2020. The survey distribution included 2230 active members of ASPS and 1149 resident members, all who practice or train within the United States. The survey consisted of 18 multiple-choice questions with answer choices based on a descriptive five-point Likert scale and ranking by priority. Statistical analysis of the results was performed using StataCorp 2019 software. RESULTS: A total of 431 completed surveys were received for a response rate of 12.7%. The majority of participants (70%) reported that personal spiritual beliefs and faith contribute positively to emotional well-being. In total, 65% agreed or strongly agreed that their spiritual beliefs provide a healthy framework for handling conflict, suffering, and loss. More than half (51%) reported that as a result of the COVID-19 global pandemic, their spiritual beliefs and practices have provided increased support and guidance. CONCLUSIONS: Spirituality is an important component of maintaining wellness for plastic surgeons, and spirituality is recognized by plastic surgeons as an important aspect of the healing process for patients. Efforts should be made to promote spiritual health among the surgical community both during training and in practice.

Incidence of Venous Thromboembolism after Sternal Reconstruction: A Single-center Retrospective Review.

BACKGROUND: Deep sternal wound infection and mediastinitis following sternotomy are associated with significant morbidity and mortality, and often require sternal reconstruction by plastic surgeons. Despite this patient population having a substantial risk of venous thromboembolism, there are no reports of the incidence of venous thromboembolism in patients undergoing sternal reconstruction. The authors sought to evaluate the incidence of venous thromboembolism in sternal reconstruction patients and to identify common risk factors for venous thromboembolism in this patient population. METHODS: A single-center retrospective review was completed of all patients who underwent sternal reconstruction by plastic surgeons between January 2012 and July 2020. Demographic data, antiplatelet and anticoagulant use, 2005 Caprini score, operative time, bleeding events, and postoperative venous thromboembolism events were recorded. RESULTS: A total of 44 patients were identified for analysis. The average 2005 Caprini score for the cohort was 10.9. In total, 93.2% of patients received perioperative antiplatelet and anticoagulant therapy (either chemoprophylaxis or systemic). Two patients developed postoperative venous thromboembolism events, for a total venous thromboembolism rate of 4.6%. Four patients had bleeding events requiring reoperation. No deaths were reported from either of these complications. CONCLUSIONS: Patients undergoing sternal reconstruction are at a high risk for venous thromboembolism and postoperative bleeding events. Despite the growing body of literature on venous thromboembolism in various surgical populations, the optimal management of thromboembolic risk in patients with high Caprini scores undergoing sternal reconstruction requires additional investigation.

Congenital Symmastia: A Comprehensive Review and Proposed Treatment Algorithm.

ABSTRACT: Congenital symmastia is a relatively uncommon condition and poorly described in the literature. Although numerous studies have evaluated iatrogenic symmastia including its prevention and treatment, considerably less has been studied with regard to congenital symmastia. In this review, the authors seek to consolidate the literature published thus far and provide techniques and principles of management that may guide surgeons treating patients with this condition.

Does Controlling for Scale Heterogeneity Better Explain Respondents' Preference Segmentation in Discrete Choice Experiments? A Case Study of US Health Insurance Demand.

Analyses of preference evidence frequently confuse heterogeneity in the effects of attribute parameters (i.e., taste coefficients) and the scale parameter (i.e., variance). Standard latent class models often produce unreasonable classes with high variance and disordered coefficients because of confounding estimates of effect and scale heterogeneity. In this study, we estimated a scale-adjusted latent class model in which scale classes (heteroskedasticity) were identified using respondents' randomness in choice behavior on the internet panel (e.g., time to completion and time of day). Hence, the model distinctly explained the taste/preference variation among classes associated with individual socioeconomic characters, in which scales are adjusted. Using data from a discrete-choice experiment on US health insurance demand among single employees, the results demonstrated how incorporating behavioral data enhances the interpretation of heterogeneous effects. Once scale heterogeneity was controlled, we found substantial heterogeneity with 4 taste classes. Two of the taste classes were highly premium sensitive (economy class), coming mostly from the low-income group, and the class associated with better educational backgrounds preferred to have a better quality of coverage of health insurance plans. The third class was a highly quality-sensitive class, with a higher SES background and lower self-stated health condition. The last class was identified as stayers, who were not premium or quality sensitive. This case study demonstrates that one size does not fit all in the analysis of preference heterogeneity. The novel use of behavioral data in the latent class analysis is generalizable to a wide range of health preference studies.

QALYs for COVID-19: A Comparison of US EQ-5D-5L Value Sets.

BACKGROUND: In economic evaluations, quality-adjusted life-years (QALYs) can serve as a unit of measurement for disease burden. Obtaining QALY values for COVID-19 presents a challenge owing to the availability of two US EQ-5D-5L value sets and the potentially asymptomatic presentation of the disease. The first value set was completed allowing for the discounting of future health outcomes while the second value set is undiscounted. OBJECTIVE: The objective of this study was to compare the distribution of QALY values using a national survey and the two published value sets; and to estimate the association between COVID-19 outcomes and QALY losses. METHODS: Between 9 and 11 November, 2020, 1153 US adults completed the EQ-5D-5L instrument (five items and a visual analog scale) as well as self-reported their demographics, COVID-19 symptoms, and memberships to populations that are at risk of COVID-19 infection. The two US value sets were applied to the EQ-5D-5L responses to produce QALY values. We estimated the mean QALYs by visual analog scale decile and a generalized linear model of COVID-19 outcomes. RESULTS: The discounted values are higher than the undiscounted values for each visual analog scale decile owing to methodological differences. Persons at increased risk, with a fever in the past day, and with one or more other symptoms have significantly greater QALY losses (p < 0.01). Overall, non-institutionalized individuals at risk of symptomatic clinical COVID-19 equal 0.68 for the 2016 value set (95% confidence interval 0.49-0.87) and 0.10 for the 2017 value set (95% confidence interval - 0.31 to 0.51) QALYs. CONCLUSIONS: Multiple studies have shown that decision makers discount future health outcomes, which increase QALY values. This study confronts the practical implications of these methodological advances for use in COVID-19 economic evaluations. Health economists will be able to use the QALY values in this study to better evaluate health interventions against COVID-19.

Negative pressure wound therapy: device design, indications, and the evidence supporting its use.

Introduction: Negative pressure wound therapy (NPWT) has become a mainstay in the armamentarium for wound care. Since the initial commercial vacuum-assisted closure device became available in 1995, subsequent research has confirmed the positive physiological effects of negative pressure on wound healing. Traditionally, NPWT has been used to improve healing of open nonsurgical wounds by secondary intention. However, the clinical applications of NPWT have significantly broadened, and now also include use in open surgical wounds, closed surgical incisions, and skin graft surgery. In addition, devices have evolved and now include functionality and features such as instillation, antimicrobial sponges, and portability.Areas covered: This article reviews the history, background, and physiology underlying NPWT, as well as the most commonly used devices. In addition, an evidence-based discussion of the current clinical applications of NPWT is presented, with a focus on those with high levels of evidence.Expert opinion: Future directions for device development include modifications to increase ease of use by patients and to allow its use in a broader array of anatomic areas. Lastly, more research with high levels of evidence is needed to better define the outcomes associated with NPWT, including in relation to specific clinical applications and cost.

Surgical Residents' Perceptions of the Impact of Productivity-Based Faculty Compensation at an Academic Medical Center.

BACKGROUND: Academic medical centers have increasingly adopted productivity-based compensation models for faculty. The potential exists for conflict between financial incentives and the quality of surgical resident education. This study aims to examine surgical residents' perceptions regarding the impact of productivity-based compensation on education. METHODS: Following implementation of a productivity-based compensation plan, a survey of surgical residents (general surgery, plastic surgery, otolaryngology, urology, orthopedic surgery, and neurosurgery) was conducted to examine perceptions of its impact on didactics, patient care, surgical technique, teaching in the operating room, and financial considerations. Survey data were prospectively collected and analyzed. A retrospective analysis of relative value units (RVUs) was also performed. RESULTS: Following implementation of the productivity-based compensation plan, annual work RVUs increased by 8.9% in surgery as a whole, with increases observed within all surgical subspecialties. A total of 100 surveys were sent and 35 were completed (35% response rate and at least 30% within each surgical subspecialty). Forty-nine percent of participants perceived an increased focus on clinical productivity by faculty. Thirty-seven percent reported learning more about RVUs and Current Procedural Terminology coding. Most residents reported that the compensation plan did not have an impact on their education with respect to didactics (77%), patient care (94%), surgical technique (97%), and teaching in the operating room (83%). CONCLUSIONS: Increased clinical productivity in the setting of an RVU-based compensation plan was not perceived by most surgical residents to have impacted their education. In some cases, this model may enhance education in relation to RVUs, Current Procedural Terminology coding, and the financial aspects of surgery.

Bridging Acellular Dermal Matrix in Abdominal Wall Repair following Radical Resection of Recurrent Endometrioma.

The patient is a 31-year-old woman with a history of prior resection of a presumed keloid scar around her Pfannenstiel incision found to be endometrial tissue on final pathology. She presented 5 years later with recurrence of pain and a mass associated with menses despite maximal medical therapy for endometriosis. Computed tomography of her abdomen and pelvis demonstrated an infiltrative soft tissue mass measuring 8.8 cm × 4.0 cm. Surgical oncology conducted an en bloc resection of the mass and obstetrics and gynecology performed a concomitant total abdominal hysterectomy and bilateral salpingo-oophorectomy. Plastic and reconstructive surgery completed the repair of the final 23 cm × 10 cm full-thickness abdominal wall defect with bridging biologic mesh, complex layered closure, and incisional negative-pressure wound therapy. Final pathology confirmed a diagnosis of endometriosis. Patient's hospital course was uncomplicated, and follow-up at 6 months does not demonstrate clinical or radiographic evidence of bulge or hernia recurrence. Abdominal wall endometrioma is a well-documented occurrence in prior cesarean scars; plastic surgeons can contribute to a multidisciplinary approach in reconstruction when resection compromises abdominal wall integrity, necessitating expertise in complex repairs.

Instillation negative pressure wound therapy: An effective approach for hardware salvage.

Wound infection involving hardware can be notoriously difficult to treat, often requiring the removal of the infected implant. The goal of this study was to determine the utility of instillation negative pressure wound therapy to help eradicate infection and allow for definitive wound closure in patients without removing the infected hardware. A retrospective review was performed on the outcomes of 28 patients who presented with open wounds with exposed or infected hardware and who were treated with a combination of surgical debridement and negative pressure wound therapy with instillation (NPWTi). Eleven patients were treated for infected spinal hardware, 12 for extremity, and 5 for sternal hardware. Twenty-five of 28 (89%) patients had successful retention or replacement of hardware, with clearance of infection and healed wounds. Original hardware was maintained in 17 of 28 (61%) patients. In 11 patients, original hardware was removed, with subsequent replacement in eight of those patients after a clean wound was achieved. Average time to definitive closure was 12.6 days. Average follow-up was 135 days. This series supports NPWTi as an effective adjunct therapy to help expeditiously eradicate hardware infection, allowing for hardware retention.

Instillation Negative Pressure Wound Therapy: A Role for Infected LVAD Salvage.

Objective: To determine the utility of instillation negative pressure wound therapy (NPWT) in achieving eradication of infection and definitive wound closure in patients with infected left ventricular assist device (LVAD). Approach: A retrospective review was performed in a series of patients with infected and exposed LVADs who were treated with instillation NPWT in conjunction with surgical debridement. Results: Three consecutive patients were included who developed periprosthetic infection subsequent to LVAD implantation. In all cases, the utilization of a vacuum-assisted closure with instillation (VACi) along with surgical debridement and IV antibiotics eradicated infection resulting in successful retention of hardware. Cases 1 and 2 received definitive wound closure within 3 and 12 days of starting treatment, respectively. Case 3 initially deferred surgery in favor of local wound care. Eventually the patient elected for surgical treatment and underwent closure 164 days after initial presentation. All three patients healed completely without residual evidence of infection. Flap reconstruction with a pedicled rectus flap was used to achieve definitive closure in all patients. One patient subsequently required pump replacement secondary to thrombosis and mechanical pump failure. Innovation: LVAD infections are met with high morbidity and mortality rates, and timely salvage is critical. In this initial series, VACi has proven a viable therapy option to help control and eradicate infection without LVAD removal. Conclusion: This series illustrates the value of newer techniques such as VACi in combination with surgical debridement and antibiotic therapy in effectively salvaging LVADs that were infected.

The Value Employees Place on Health Insurance Plans: A Discrete-Choice Experiment.

BACKGROUND: The federally-facilitated Health Insurance Marketplace-also known as the Health Insurance Exchange-was designed as a tool to help people purchase insurance plans, yet many Americans remain uninsured, partially due to rising premiums. One possible strategy to stabilize its premiums is to encourage healthier people to purchase their plans through the Marketplace instead of through their employers. OBJECTIVE: This study examined the values that single adults with employer-based coverage place on health insurance plan attributes using a discrete-choice experiment (DCE). METHODS: As part of an online survey, each respondent completed 28 paired comparisons trading off four attributes: source of coverage, plan type, monthly out-of-pocket premium, and quality of coverage. RESULTS: Based on our results (N = 2207), single employees slightly preferred their employer over the Marketplace as a source of coverage (0.726 odds ratio; p value < 0.01). Single employees would be willing to switch to the Marketplace for a US$25 reduction in monthly premiums. Preferred Provider Organization (PPO) plans were overwhelmingly preferred over all other plan types, especially compared to Fee-for-Service (FFS) plans (4.230 odds ratio; p value < 0.01). The predicted probability that a health insurance plan from the Marketplace would be chosen ranged from 42 to 43.7%. CONCLUSION: This study demonstrated that a US$25 subsidy or providing slightly more generous coverage (Bronze-Silver) would motivate employees to purchase PPO plans through the Marketplace, potentially improving its risk pooling, reducing employers' administrative burden, and enhancing labor mobility.

Five-step Correction of Congenital Symmastia.

Congenital symmastia is distressing and difficult to treat, and traditional surgical modalities have met with limited success. We present a novel approach for a patient that failed all traditional surgical options. The anatomic deformity is analyzed using a modified version of Blondeel's 3-step analysis (conus, footprint, and skin envelope, to which we added a fourth element "intermammary web"). Combining operative principles from breast cancer reconstruction, we describe 5 operative steps that help correct the deformity, followed by a new postoperative splinting regimen that addresses the common pitfalls that could lead to recurrence.

Adjuvant radiation therapy increases disease-free survival in stage IB Merkel cell carcinoma.

Merkel cell carcinoma (MCC) is a rare and aggressive cutaneous malignancy. Adjuvant radiation increases survival in advanced stages, but efficacy in stage I disease is unknown. A retrospective review included all patients treated for stage I MCC during a 15-year period at Vanderbilt University Medical Center. Among 42 patients, 26 (62%) had a negative sentinel lymph node biopsy (stage IA) and 16 (38%) had clinically negative lymph nodes (stage IB) at the time of resection. Analysis using Cox regression revealed that higher stage and absence of adjuvant radiation are associated with increased disease recurrence (hazard ratio, 6.29; P=0.003 and hazard ratio, 4.69; P=0.013, respectively). Controlling for stage, radiation therapy significantly increased disease-free survival among patients with stage IB disease (P=0.0026) in a log-rank test comparing Kaplan-Meier curves. These findings support adjuvant radiation therapy in stage IB MCC patients with clinically negative lymph nodes who do not undergo sentinel lymph node biopsy.

Veterans Affairs general surgery service: the last bastion of integrated specialty care.

BACKGROUND: In a time of increasing specialization, academic training institutions provide a compartmentalized learning environment that often does not reflect the broad clinical experience of general surgery practice. This study aimed to evaluate the contribution of the Veterans Affairs (VA) general surgery surgical experience to both index Accreditation Council for Graduate Medical Education (ACGME) requirements and as a unique integrated model in which residents provide concurrent care of multiple specialty patients. METHODS: Institutional review board approval was obtained for retrospective analysis of electronic medical records involving all surgical cases performed by the general surgery service from 2005 to 2009 at the Nashville VA. Over a 5-year span general surgery residents spent an average of 5 months on the VA general surgery service, which includes a postgraduate year (PGY)-5, PGY-3, and 2 PGY-1 residents. Surgeries involved the following specialties: surgical oncology, endocrine, colorectal, hepatobiliary, transplant, gastrointestinal laparoscopy, and elective and emergency general surgery. The surgeries were categorized according to ACGME index requirements. RESULTS: A total of 2,956 surgeries were performed during the 5-year period from 2005 through 2009. Residents participated in an average of 246 surgeries during their experience at the VA; approximately 50 cases are completed during the chief year. On the VA surgery service alone, 100% of the ACGME requirement was met for the following categories: endocrine (8 cases); skin, soft tissue, and breast (33 cases); alimentary tract (78 cases); and abdominal (88 cases). Approximately 50% of the ACGME requirement was met for liver, pancreas, and basic laparoscopic categories. CONCLUSIONS: The VA hospital provides an authentic, broad-based, general surgery training experience that integrates complex surgical patients simultaneously. Opportunities for this level of comprehensive care are decreasing or absent in many general surgery training programs. The increasing level of responsibility and simultaneous care of multiple specialty patients through the VA hospital systems offers a crucial experience for those pursuing a career in general surgery.

Inpatient mortality and length of stay comparison of percutaneous endoscopic gastrostomy and percutaneous endoscopic gastrojejunostomy.

INTRODUCTION: Percutaneous endoscopic gastrostomy (PEG) and percutaneous endoscopic gastrojejunostomy (PEGJ) are endoscopic procedures often performed by surgeons. No recent population-based study has compared inpatient mortality or length of stay between patients who undergo PEG or PEGJ placement during their hospitalization. METHODS: Patients undergoing inpatient PEG or PEGJ placement and who were at least 18 years old were identified from the 2006 Nationwide Inpatient Sample (NIS) database. Baseline characteristics of each group were compared, and outcomes of risk-adjusted inpatient mortality and length of stay were determined. Means were compared from using a complex sample t-test, and proportions were compared from using a complex sample chi-square test, with an alpha level of 0.05 for significance. Bivariate logistic regression was used to evaluate PEG or PEGJ placement as a risk factor for mortality. RESULTS: In the 2006 NIS, 187,597 discharges were identified, during which a PEG or PEGJ was placed. Ninety-six percent (179,587) of patients underwent PEG placement, and 4% (8010) had PEGJ tubes placed. Fifty-one percent were men, with the mean age for PEG and PEGJ placement of 71.3 +/- 0.3 (mean +/- standard error) and 64.8 +/- 0.8 years (P < 0.05). In the PEG group, 86% of admissions were nonelective, compared to 79% in the PEGJ group (P < 0.05). The primary discharge diagnoses for both groups of patients included acute cerebrovascular disease, aspiration pneumonitis, septicemia, respiratory failure, and intracranial injury. PEG patients had a higher cumulative incidence of congestive heart failure, chronic lung disease, and diabetes. Crude in-hospital mortality for death was 11% for both PEG and PEGJ patients. No difference in mortality was observed in risk-adjusted analyses accounting for patient severity. Mean length of stay was similar for both groups (PEG 20.9 +/- 0.4 days; PEGJ 22.5 +/- 1.1 days). Neither PEG nor PEGJ was identified as a risk factor for inpatient mortality. CONCLUSIONS: Comparative analyses of patients undergoing PEG versus PEGJ revealed no detectable difference between inpatient mortality and hospital length of stay in this large observational study. Both procedures can be performed safely in high-risk populations, with no increased mortality or length of stay incurred by jejunal feeding access. However, further analysis is required to compare more specific short-term outcomes between these populations as well as their respective cost-effectiveness.

Light-mediated inhibition of protein synthesis.

The regulation of protein synthesis is vital for a host of cell biological processes, but investigating roles for protein synthesis have been hindered by the inability to selectively interfere with it. To inhibit protein synthesis with spatial and temporal control, we have developed a photo-releasable anisomycin compound, N-([6-bromo-7-hydroxycoumarin-4-yl]methyloxycarbonyl)anisomycin (Bhc-Aniso), that can be removed through exposure to UV light. The area of protein synthesis inhibition can be restricted to a small light-exposed region or, potentially, the volume of two-photon excitation if a pulsed IR laser is the light source. We have tested the compound's effectiveness with an in vitro protein-translation system, CHO cells, HEK293 cells, and neurons. The photo-released anisomycin can inhibit protein synthesis in a spatially restricted manner, which will enable the specific inhibition of protein synthesis in subsets of cells with temporal and spatial precision.
