RESUMO
OBJECTIVE: Vascular access is difficult in patients without suitable arm veins and prior graft infections. The use of femoral vein translocation (FVT) to the upper extremity or contralateral lower extremity for hemodialysis access may be associated with low infection rates and high patency rates. FVT is used for patients without central venous occlusion who have failed prior access either owing to graft infection or repetitive graft thrombosis. The largest case series consists of 30 cases. The objective of this study is to determine the infection incidence, primary patency, primary-assisted patency, and secondary patency rates among FVTs. METHODS: A retrospective chart review was performed on all patients who underwent FVT by a single vascular practice over a 10-year period (2013-2023). Study variables included length to last follow-up (months), prior access, prior graft infection, comorbid conditions, primary patency, primary-assisted patency, secondary patency, postoperative steal syndrome, postoperative graft infection, postoperative harvest site complication, and postoperative lower extremity compartment syndrome. RESULTS: A total of 131 FVTs were performed from 2013 to 2023; 126 patients (47% male, 53% female; 76% Black, 24% White) with a mean age of 52 ± 14 years and a mean body mass index of 29 ± 8 had at least 1 month of follow-up and were included for analysis. The median follow-up was 46 months (interqurtile range, 19-72 months). The mean number of prior permanent accesses was 2.5 ± 1.4. Forty-eight percent of patients had prior graft infections. The primary, primary-assisted, and secondary patency rates were 66%, 93%, and 98%, respectively, at 6 months; 43%, 85%, and 96% at 12 months; 25%, 70%, and 92% at 24 months; 16%, 61%, and 88% at 36 months; and 14%, 56%, and 82% at 48 months. Postoperative steal syndrome and postoperative access infection requiring excision was observed 16% and 5% of patients, respectively. Harvest site complications requiring an additional procedure occurred in 19% of cases. Three patients developed lower extremity compartment syndrome postoperatively, requiring fasciotomy. Six patients developed chronic lower extremity edema after femoral vein harvest. The mean procedure time and hospital length of stay were 197 ± 40 minutes and 3.5 ± 2.8 days, respectively. CONCLUSIONS: FVT is associated with low infection rates and high long-term patency rates. Significant postoperative complications include steal syndrome and harvest site complications. FVT remains a viable option for patients who have failed prior access owing to graft infection or repetitive graft thrombosis.

INTRODUCTION: Previous studies have demonstrated worse outcomes for Hirschsprung's disease (HD) procedures in Trisomy 21 (T21) patients. Using a large national database, we sought to investigate surgical outcomes in HD patients with T21 compared to non-T21 patients. METHODS: We utilized the deidentified National Surgical Quality Improvement Program Pediatric database from 2012 to 2021. Using International Classification of Diseases, Ninth Revision codes, children <18 y old with HD were included and stratified by T21 diagnosis. Demographics, Current Procedural Terminology codes, case characteristics, length of hospital stay, and postoperative complications were analyzed. RESULTS: Of 3456 HD patients, 12.0% (n = 413) patients had a concurrent diagnosis of T21. Pull-through (PT) procedures accounted for 54.9% of surgeries (n = 1896), of which 10.0% (n = 189) had T21. T21 patients who underwent PT had a younger gestational age (P < 0.0001), cardiac risk factors (P < 0.0001), hematologic disorders (P < 0.0001), higher American Society of Anesthesiologists class (P < 0.0001), and were older at their index operation (P = 0.03). Though operative times were similar, T21 patients had a longer total length of stay (P = 0.0263), postoperative length of stay (P = 0.0033), and more unplanned reoperations (P = 0.0094). Though only significant in unadjusted analyses, T21 patients had more postoperative complications after PT (P = 0.0034), specifically deep surgical site infections (P = 0.009), organ/space surgical site infections (P = 0.004), wound disruption (P < 0.001), and sepsis (P = 0.025). CONCLUSIONS: We confirm significant differences exist between T21 and non-T21 patients undergoing HD procedures, particularly increased total length of stay, postoperative length of stay, and unplanned reoperations. Understanding these differences will lead to more optimal treatment plans for this unique patient population.
RESUMO
INTRODUCTION: The virtual residency application season posed numerous challenges for the 2021 residency match process. Many residency programs are exploring relationships between this novel format and the match process. The purpose of this study was to compare one of the largest general surgery residency program's applications and match data from preCOVID years to the 2021 virtual cycle. MATERIALS AND METHODS: A retrospective review was performed of applicants to a single general surgery residency program from 2017 to 2021. The primary outcome was the number of locally matched applicants. The secondary outcomes were the total number of applications, change in applicant demographics, and variability of the geographic spread during this study period. Chi-square tests of independence, Fisher's exact tests, and negative binomial regression were performed. RESULTS: 6819 applicants were included in the study. In 2021, an increase in applications was observed. The distribution of 2021 applications was statistically different from previous years regarding gender and race (P < 0.0001). The 2021 application cycle had a greater proportion of applicants from the United States (P < 0.0001) and southern US medical schools (P = 0.008). While the 2021 cycle had significantly more interviews (P = 0.013), there were no significant differences in the demographic composition of interviewees. During the 2021 application year, all 11 matches were from southern medical schools and there was a trend to more matched female applicants compared to previous years. CONCLUSIONS: During the 2021 COVID-19 virtual match cycle, an increase in both the number of applications and number of interviews for general surgery residency was identified. The characteristics of applicants who interviewed and matched were not different when compared to previous years. As virtual interviews may become more commonplace, it is important to assess all factors that may be involved in the dynamic residency application process.

BACKGROUND: Disadvantaged neighborhood environments are a source of chronic stress which undermines optimal adolescent health. This study investigated relationships between the neighborhood social environment, specifically, chronic stress exposures, adiposity, and cardiometabolic disease risk factors among 288 Louisiana adolescents aged 10 to 16 years. METHODS: This cross-sectional study utilized baseline data from the Translational Investigation of Growth and Everyday Routines in Kids (TIGER Kids) study. Adolescent data were obtained using self-reported questionnaires (demographics and perceived neighborhood disorder), anthropometry, body imaging, and a blood draw while objective neighborhood data for the concentrated disadvantage index were acquired from the 2016 American Community Survey five-year block group estimates, 2012-2016. Multilevel linear regression models were used to examine whether neighborhood concentrated disadvantage index and perceived neighborhood disorder were associated with body mass index, waist circumference, body fat, adipose tissue, blood pressure, and lipids. We performed multilevel logistic regression to determine the odds of elevated adiposity and cardiometabolic disease risk for adolescents living in neighborhoods with varying levels of neighborhood concentrated disadvantage and disorder. RESULTS: Adolescents living in neighborhoods with higher disadvantage or disorder had greater waist circumference and total percent body fat compared to those in less disadvantaged and disordered neighborhoods (p for trend < 0.05). Neighborhood disadvantage was also positively associated with percentage of the 95th Body Mass Index percentile and visceral abdominal adipose tissue mass while greater perceived neighborhood disorder was related to higher trunk fat mass and diastolic blood pressure (p for trend < 0.05). Living in the most disadvantaged was associated with greater odds of obesity (OR: 2.9, 95% CI:1.3, 6.5) and being in the top tertile of body fat mass (OR: 3.0, 95% CI: 1.4, 6.6). Similar results were found with neighborhood disorder for odds of obesity (OR: 2.1, 95% CI:1.1, 4.2) and top tertile of body fat mass (OR: 2.1, 95% CI:1.04, 4.1). CONCLUSIONS: Neighborhood social environment measures of chronic stress exposure were associated with excess adiposity during adolescence, and relationships were most consistently identified among adolescents living in the most disadvantaged and disordered neighborhoods. Future studies should account for the influences of the neighborhood environment to stimulate equitable improvements in adolescent health. CLINICAL TRIALS REGISTRATION: # NCT02784509.

PURPOSE: Currently, rural residents in the United States (US) experience a greater cancer burden for tobacco-related cancers and cancers that can be prevented by screening. We aim to characterize geographic determinants of colorectal cancer (CRC) incidence in Louisiana due to rural residence and other known geographic risk factors, area socioeconomic status (SES), and cultural region (Acadian or French-speaking). METHODS: Primary colorectal cancer diagnosed among adults 30 years and older in 2008-2017 were obtained from the Louisiana Tumor Registry. Population and social and economic data were obtained from US Census American Community Survey. Rural areas were defined using US Department of Agriculture 2010 rural-urban commuting area codes. Estimates of relative risk (RR) were obtained from multilevel binomial regression models of incidence. RESULTS: The study population was 16.1% rural, 18.4% low SES, and 17.9% Acadian. Risk of CRC was greater among rural white residents (RR Women: 1.09(1.02-1.16), RR Men: 1.11(1.04-1.18)). Low SES was associated with increased CRC for all demographic groups, with excess risk ranging from 8% in Black men (RR: 1.08(1.01-1.16)) to 16% in white men (RR: 1.16(1.08-1.24)). Increased risk in the Acadian region was greatest for Black men (RR: 1.21(1.10-1.33)) and women (RR: 1.21(1.09-1.33)). Rural-urban disparities in CRC were no longer significant after controlling for SES and Acadian region. CONCLUSION: SES remains a significant determinant of CRC disparities in Louisiana and may contribute to observed rural-urban disparities in the state. While the intersectionality of CRC risk factors is complex, we have confirmed a robust regional disparity for the Acadian region of Louisiana.

COVID-19 morbidity and mortality are driven by poor immune regulation. Narrowband ultraviolet B (NB-UVB) phototherapy is standard of care in a number of immune-dysregulated diseases. To assess the efficacy of NB-UVB phototherapy for improving COVID-19 outcomes in high-risk, hospitalized, we developed the Adaptive Photo-Protection Trial. This is a multi-center, prospective, double-blinded, randomized, placebo-controlled trial. The pilot phase results are reported here. Consecutive patients admitted with a positive COVID-19 PCR were screened for eligibility. Enrolled subjects were computer randomized 1:1 to NB-UVB or placebo phototherapy. Subjects were treated daily with escalating doses on 27% of their body surface area for up to 8 consecutive days. Primary outcomes were safety and efficacy, defined as persistent or painful erythema and 28-day mortality. Comparisons were made via non-parametric exact tests. Patients in treatment (n = 15) and placebo (n = 15) arms had similar demographics. No adverse events occurred. Twenty eight-day mortality was 13.3% in treatment vs. 33.3% in placebo arms (p = 0.39). NB-UVB phototherapy in hospitalized COVID-19 patients was safe. Decreased mortality was observed in treated patients but this was statistically non-significant. Given its low-cost, scalability, and adjunctive nature, NB-UVB has the potential to improve COVID-19 outcomes. Continuation of this trial is warranted.

INTRODUCTION: Traumatic injury is the leading cause of pediatric mortality and morbidity in the United States. Pediatric trauma survivors requiring inpatient rehabilitation (IPR) require coordinated, multispecialty follow-up. Knowledge of the nature and level of disability is necessary for planning this continued care that is specific to the needs of pediatric trauma patients. This study aims to describe the outcomes of pediatric and adolescent trauma patients using measures of functional progression. MATERIALS AND METHODS: A retrospective review of trauma patients aged ≤18 y admitted to IPR between January 2018 and December 2020 at the only certified pediatric rehabilitation center in the region was performed. RESULTS: Ninety five children and adolescents were admitted to IPR after traumatic injury with diagnoses of multitrauma (MT, N = 18), traumatic brain injury (TBI, N = 59), and spinal cord injury (SCI, N = 18). School aged children returned to school at high rates for all injury types (MT: 86.7%, TBI: 97.4%, SCI: 93.8%, P = ns). All groups had similar hospital and rehabilitation length of stay, and most patients required a durable medical equipment at discharge (79%). Using pediatric functional independence measure scoring progression from admission to discharge from IPR, SCI patients made significant improvement in bladder function and the least improvement in stair function. Patients sustaining a TBI made significant improvement in memory and comprehension tasks. CONCLUSIONS: Pediatric and adolescent trauma patients admitted to IPR had a positive progression during their therapy but required variable ongoing care depending on the mechanism of injury. Excellent rates of returning to school were seen across the three injury types.

BACKGROUND: Currently there are no standard of care treatment strategies for IH prevention (IHP). Dehydrated human amnion-chorion (dHACM) is a healing adjunct that elutes growth factors including several that have reduced IH in animal models. We therefore performed a double-blinded, prospective randomized controlled trial (RCT) to test the hypothesis that dHACM significantly reduces IH formation in a well-studied animal model of acute IH. MATERIAL AND METHODS: Forty 16-week-old male Sprague-Dawley rats were randomized to one of four groups: No Treatment vs. dHACM Sheet (Group A), and Saline vs. dHACM Injection (Group B). Each animal underwent a 5-cm midline laparotomy which was incompletely closed with 5-0 plain gut sutures; this was performed by a surgeon blinded to treatment group (first blind). After 28 days, the primary endpoints of IH formation and hernia size were determined by study staff blinded to treatment (second blind). Secondary endpoints included healed fascia tensile strength as determined by tensiometry, systemic and local inflammatory markers as measured by ELISA, and fascial scar collagen I/III ratios per Western blotting. RESULTS: In Group A, No Treatment developed IH at 87.5% vs. 62.5% for Sheet (P = 0.28). Hernias that formed in the Sheet group were significantly smaller (P = 0.036). In Group B, Injection and Saline yielded identical IH rates of 77.8%. Molecular characterization of fascial scar demonstrated non-inferior tensile strength, collagen I/III ratios, and inflammatory markers in dHACM-treated animals. CONCLUSIONS: dHACM sheets significantly reduced the size of IH following laparotomy when compared to no treatment.

BACKGROUND: The profunda femoris artery (PFA) supplies important collateral branches to both the ipsilateral internal iliac artery and the distal superficial femoral artery (SFA). The size and patency of these collateral pathways can determine the risk of pelvic malperfusion, spinal cord ischemia, and lower extremity limb loss following vascular interventions. Despite its importance, the anatomy of the PFA is rarely characterized in clinical studies involving the pelvic or lower extremity circulation. This discussion may be limited by the lack of a comprehensive classification system. Our objective was to describe the most common PFA anatomic variants and present a classification system based on its branching patterns. METHODS: We dissected 155 fixed and nonfixed femoral artery systems from 88 cadavers. Seventy-seven female and 78 male femoral exposures were performed. Vessel diameters, branch configurations, and relative distances between the inguinal ligament, PFA, lateral circumflex femoral artery (LCFA), and medial circumflex femoral artery (MCFA) were recorded. RESULTS: The mean diameters of the common femoral artery, SFA, and PFA were 10.3 mm, 8.0 mm, and 6.9 mm in males and 8.9 mm, 6.9 mm, and 6.1 mm in females, respectively (P < 0.05). The mean distances from the inguinal ligament for PFA, MCFA, and LCFA were 41 mm, 41.7 mm, and 52.5 mm, respectively. No significant differences were noted relative to laterality or fixation. We developed a clinically applicable classification system based on the orientation of the PFA, LCFA, and MCFA. Six PFA, 5 LCFA, and 5 MCFA variations were identified and ranked by frequency. The 5 most common combinations accounted for 56.1% of our cadaver series. CONCLUSIONS: The anatomic orientation of the PFA and its branches is highly variable. We propose a novel classification system of this rich collateral system to facilitate consistent communication in academic and clinical vascular surgery.

BACKGROUND: The deep inferior epigastric perforator flap (DIEP) is a widely known reliable option for autologous breast reconstruction. One common complication of DIEP procedures is fat necrosis. Consequences of fat necrosis include wound healing complications, pain, infection, and the psychological distress of possible cancerous recurrence. Clinical judgment alone is an imperfect method to detect at-risk segments of adipose tissue. Objective methods to assess perfusion may improve fat necrosis complication rates, reducing additional surgeries to exclude cancer and improve cosmesis for patients. METHODS: The authors performed a retrospective review of patients who underwent analysis of DIEP flap vascularity with or without intraoperative indocyanine green angiography (ICGA). Flap perfusion was assessed using intravenous ICGA and was quantified with both relative and absolute value units of fluorescence. Tissue with observed values less than 25% to 30% relative value units was resected. Postoperative outcomes and fat necrosis incidence were collected. RESULTS: Three hundred fifty-five DIEP flaps were included in the study, 187 (52.7%) of which were assessed intraoperatively with ICGA. Thirty-nine patients (10.9%) experienced operable fat necrosis. No statistically significant difference in incidence of postoperative fat necrosis was found between the 2 groups (P = 0.732). However, a statistically significant relationship was found between fat necrosis incidence and body mass index as both a continuum (P = 0.001) and when categorized as greater than 35 (P = 0.038). CONCLUSIONS: Although ICGA is useful for a variety of plastic surgery procedures, our retrospective review did not show a reduction in operable fat necrosis when using this technology.

OBJECTIVE: In the present study, we sought to understand the challenges, advantages, and applications of a vascular surgery virtual subinternship (VSI) curriculum. METHODS: Our institution hosted 25 students for two 4-week VSI rotations, one in July 2020 and one in August 2020. The students participated in a curriculum centered around the use of Zoom and telephone interactions with residents and faculty. The curriculum included selected readings, surgical videos, group didactics, and one-on-one mentorship. Anonymous pre- and postrotation self-assessments were used to ascertain the students' achievement of the learning objectives and the utility of the educational tools implemented during the rotation. The faculty and resident mentors were also surveyed to assess their experience. RESULTS: With the exception of knot-tying techniques (P = .67), the students reported significant improvement in their understanding of vascular surgery concepts after the virtual elective (P < .05). The highest ranked components of the course were interpersonal, including interaction with faculty, mentorship, and learning the program culture. The lowest ranked components of the course were simulation training and research opportunities. The rating of the utility of aspects of the course were consistent with the ranking of the components, with faculty interaction receiving the highest average rating. The ideal amount of time for daily virtual interaction reported by the students ranged from 3 to 6 hours (median, 4 hours). Overall, most of the mentors were satisfied with the virtual course. However, they reported limited ability to assess the students' personality and fit for the program. The time spent per week by the mentors on the virtual vascular surgery rotation ranged from 2 to 7 hours (median, 4 hours). Of the 17 mentors completing the surveys, 14 reported that having a virtual student was a significant addition to their existing workload. CONCLUSIONS: Overall, our student and mentor feedback was positive. Several challenges inherent to the virtual environment still require refinement. However, the goals of a VSI are distinct and should be explored by training programs. With changes to healthcare in the United States on the horizon and the constraints resulting from the severe acute respiratory syndrome coronavirus 2 pandemic, implementing a virtual away rotation could be an acceptable platform in our adaptations of our recruitment strategies.

Racial/ethnic and socioeconomic disparities in COVID-19 burden have been widely reported. Using data from the state health departments of Alabama and Louisiana aggregated to residential Census tracts, we assessed the relationship between social vulnerability and COVID-19 testing rates, test positivity, and incidence. Data were cumulative for the period of February 27, 2020 to October 7, 2020. We estimated the association of the 2018 Social Vulnerability Index (SVI) overall score and theme scores with COVID-19 tests, test positivity, and cases using multivariable negative binomial regressions. We adjusted for rurality with 2010 Rural-Urban Commuting Area codes. Regional effects were modeled as fixed effects of counties/parishes and state health department regions. The analytical sample included 1160 Alabama and 1105 Louisiana Census tracts. In both states, overall social vulnerability and vulnerability themes were significantly associated with increased COVID-19 case rates (RR 1.57, 95% CI 1.45-1.70 for Alabama; RR 1.36, 95% CI 1.26-1.46 for Louisiana). There was increased COVID-19 testing with higher overall vulnerability in Louisiana (RR 1.26, 95% CI 1.14-1.38), but not in Alabama (RR 0.95, 95% CI 0.89-1.02). Consequently, test positivity in Alabama was significantly associated with social vulnerability (RR 1.66, 95% CI 1.57-1.75), whereas no such relationship was observed in Louisiana (RR 1.05, 95% CI 0.98-1.12). Social vulnerability is a risk factor for COVID-19 infection, particularly among racial/ethnic minorities and those in disadvantaged housing conditions without transportation. Increased testing targeted to vulnerable communities may contribute to reduction in test positivity and overall COVID-19 disparities.

BACKGROUND: Sarcopenia is linked to poor outcomes throughout the surgical literature and can be assessed on preoperative imaging to potentially aid in risk stratification. This study examined the effects of sarcopenia on surgical morbidity following lower extremity (LE) reconstruction, and also compared two methods of assessment, one of which is novel ("ellipse method"). METHODS: A retrospective cohort study of 50 patients receiving free flap-based reconstruction of the LE was performed. Bilateral psoas density and area were quantified at L4 through tracing ("traditional method") and encircling ("ellipse method") to calculate Hounsfield unit average calculation (HUAC). Logistic regression and receiving operator curve analysis for the primary outcome of any postoperative complication was used to determine HUAC cutoffs (≤ 20.7 vs. ≤ 20.6) for sarcopenia. Risk of complications associated with sarcopenia was evaluated using Fisher's exact tests. RESULTS: Twelve patients (24%) met criteria for sarcopenia via the traditional method and 16 (32%) via the ellipse method. By both methods, sarcopenic patients were older and more often female and diabetic. These patients also had higher American Society of Anesthesiologists scores and lower serum prealbumin levels. The ellipse method was found to be more accurate, sensitive, and specific than the traditional method in predicting postoperative morbidity (p = 0.009). Via the ellipse method, sarcopenic patients were at higher risk for any complication (p = 0.002) and were at a higher risk for a deep vein thrombus or pulmonary embolism via the traditional method (p = 0.047). CONCLUSION: Sarcopenia is associated with greater pre- and postoperative morbidity in LE reconstruction. The novel ellipse method is a simplified and accurate method of assessing sarcopenia that can be easily performed in the clinical setting.

BACKGROUND: Harvest of the radial forearm flap (RFF) for reconstructive surgery is proceeded by the Allen test to assess for adequate contralateral perfusion of the hand, yet the Allen test may fail to detect anatomical variations in the radial artery such as aberrant branching. Therefore, the goal of this study was to systematically review the literature regarding anatomical abnormalities of the radial artery that can affect flap harvest and to perform a meta-analysis to estimate the prevalence of such abnormalities. METHODS: A systematic review of the literature was conducted using five online databases to identify all instances of radial artery anatomical variations. Abstracts were reviewed and categorized into either (1) large cohort studies of anatomical variations identified by angiogram or (2) case reports specifically mentioning anomalous or accessory branches of the radial artery. Data from the large cohort studies were included in a random effect meta-analysis to estimate the prevalence of such variations. RESULTS: Eighteen angiogram cohort studies containing a total of 18,115 patients were included in the meta-analysis. Accessory branches were the least common anatomical variant reported, with an estimated average prevalence of 0.5%. Prevalence estimates for more common anatomical variants, including radial artery loops (0.9%), stenosis (1.3%), hypoplasia (1.9%), tortuosity (4.3%), and abnormal origin (5.6%), were also calculated. Thirteen case reports detailing anomalous branches of the radial artery were identified, seven of which involved accessory branches encountered during RFF harvest with no incidence of flap loss. CONCLUSION: Radial artery accessory branches are exceedingly rare, but the prevalence of other anatomical variations that can affect harvest of the RFF warrants consideration. We recommend surgeons consider comprehensive screening prior to RFF harvest to avoid intraoperative discovery of anatomical variants and suggest a low threshold for repeat perfusion testing intraoperatively if radial artery accessory branches are encountered.

Background and Objectives: Robotic-assisted surgery advancements have paralleled growing bariatric surgery demands. The Senhance robotic platform offers an alternative to the da Vinci surgical system but there are limited studies evaluating the Senhance system in bariatric surgery. This study aims to review a single surgeon's experience comparing outcomes between traditional laparoscopic and Senhance-assisted sleeve gastrectomy. Materials and Methods: All sleeve gastrectomies performed laparoscopically, Senhance-assisted, or da Vinci-assisted by a single surgeon at an academic center from January 2019 to July 2021 were retrospectively reviewed. Primary outcomes and quality measures were 30-day complications, operative times and length of stay. Results: A total of 268 patients, including 162 laparoscopic, 92 Senhance, and 14 da Vinci cases, were included. Operative times were significantly longer with Senhance (115.7 min) and da Vinci (122.7 min), compared to laparoscopic (94.8 min, P < .0001). Length of stay (measured in days) was significantly longer in the Senhance (1.8) and da Vinci (2.2) groups compared to laparoscopic cases (1.5, P < .0001). These differences remained significant after controlling for age, sex and body mass index. 30-day complication rates were 8.7% (n = 8) in the Senhance group, 7.1% (n = 1) in the da Vinci group and 2.5% (n = 4) in the laparoscopic group (P = .0567). Conclusion: Senhance-assisted sleeve gastrectomy is safe in bariatric surgery and comparable to laparoscopic sleeve gastrectomy with respect to 30-day complications.

BACKGROUND: Metabolic surgery (MS) is effective in improving renal parameters for individuals with obesity and chronic kidney disease (CKD). Despite recognized benefits, concerns linger about the perioperative safety of patients with CKD undergoing MS. This study aimed to identify the CKD stage associated with the most significant increase in postoperative complications. METHODS: The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database (2017-2021) was used to identify patients undergoing laparoscopic gastric sleeve (SG) or Roux-en-Y gastric bypass (RYGB). Propensity matching was used to quantify the risk for adverse outcomes associated with progressive CKD stage. RESULTS: In total, 688,583 patients (483,898 without CKD and 204,685 with CKD stages I-V) were examined. Endpoints included length of stay (LOS) >5 days, infection, serious complications, major adverse cardiovascular events (MACE), and death. Both SG and RYGB exhibited a linear increase in risk of infection and death. For SG, patients who were stage IIIa/IIIb demonstrated the greatest risk for LOS >5 days (odds ratio [OR] 1.23; 95% confidence interval [CI] (1.05-1.45); P = .011), serious complications (OR 2.83; 95% CI 1.87-4.30; P < .001), and MACE (OR 2.82; 95% CI 1.81-4.37; P < .001). For RYGB, patients who were stage IIIa/IIIb the exhibited greatest risk of MACE (OR 1.67; 95% CI 1.06-2.62; P = .027). CONCLUSIONS: Although it is generally accepted that worsening CKD correlates with greater surgical risk, this analysis identified CKD stage III as a major inflection point for risk of LOS >5 days, serious complications, and MACE. These findings are useful for counseling and procedure selection and suggest a need for heightened attention to CKD stage III patients undergoing MS.

BACKGROUND: The Metabolic and Bariatric Surgery Quality Improvement Project (MBSAQIP) is the largest bariatric surgery-specific clinical data set. OBJECTIVES: In 2020, the definition of emergency cases was altered to include only revisional or conversion cases and not primary cases. The aim of this study was to examine how this change affects the utility of the data set for emergency case tracking. SETTING: MBSAQIP database. METHODS: Emergency cases were extracted from available MBSAQIP data (2015-2021). A comparison of co-morbidity profiles was done, specifically before and after the recent change to how "emergency" is defined in the data set. RESULTS: Eleven thousand and twenty-nine of the 1,048,575 total cases were coded as "emergency cases." From 2015 to 2019, 10,574 emergency cases were performed (â¼2115 cases/yr), markedly decreasing in 2020 and 2021 to 455 cases (â¼228 cases/yr). Before 2020, the most common procedures were the unlisted procedure of the stomach (45.14%, n = 3101), gastric band removal (25.3%, n = 2676), and reduction of internal hernia (11.8%, n = 1244). Between 2020 and 2021, this distribution changed with Roux-en-Y gastric bypass (RYGB), the most common emergency procedure (29.23%, n = 133). As expected from the change that captured only revisional cases, the average operative length was greater between 2020 and 2021 (127.6 versus 86.5 min). CONCLUSIONS: Capturable emergency cases declined in 2020, a trend related to changing the definition of emergency as part of MBSAQIP standards. This change excludes data on internal hernia reduction and does not likely reflect a real change in the prevalence of emergency bariatric cases. Because capture for emergency cases has diminished, so has any prior utility of using MBSAQIP data for studying emergency cases.

PURPOSE: Marginal ulceration (MU) following Roux-en-Y gastric bypass (RYGB) is an established complication, with early MU (within 30-days of operation) being less understood compared to its late counterpart. This study aims to identify risk factors for early MU in patients undergoing primary RYGB. METHODS: Utilizing data from the Metabolic and Bariatric Surgery Accreditation Quality Improvement Project (MBSAQIP 2015-2021), 1,346,468 records were evaluated. After exclusions for revisions, conversions, pediatric cases, nonbinary gender, missing body mass index (BMI) data, and missing operative time; 291,625 cases of primary RYGB were included for full analysis and rare events modeling of early MU. RESULTS: The prevalence of early MU was .29% (n = 850). Higher rates of early MU were associated with BMI, race, history of diabetes mellitus (DM), prior thrombotic complications (deep vein thrombosis (DVT) and pulmonary embolism (PE)), prior percutaneous cardiac intervention (PTC), immunosuppressive therapy, and anticoagulation status. Additionally, procedural aspects like the nonspecialization of the surgeon and longer operative times also correlated with higher early MU rates. Rare-events regression modeling noted significant associations of early MU with younger age, diabetes requiring insulin, history of PTC, DVT, immunosuppressive therapy, and anticoagulation status. CONCLUSION: Early MU remains a relatively rare complication. The lower than previously reported occurrence suggests possible improvements in both patient preparation and surgical technique. The identification of relevant risk factors enables better perioperative and intraoperative management of patients at risk of developing early MU.
RESUMO
Burn injuries often lead to psychological distress, from depression and anxiety to adjustment concerns and posttraumatic stress. There is some evidence that the anatomical location of burn injuries (eg, head/neck, feet) has a specific negative effect on psychological functioning. The purpose of this study was to examine the associations between burn injury location and emotional distress. First, we administered self-report questionnaires to burn survivors with ≤ 5% TBSA at a single adult outpatient burn clinic. Second, we used a cross-sectional analysis of the Burn Model System National Database. The mean values of each measure of psychological distress (ie, quality of life, self-esteem, depression, posttraumatic stress, anxiety, and, for contrast, posttraumatic growth) were examined for each anatomical location for those participants with a burn in those anatomical areas against those with burn in other areas. Using Kruskal-Wallis tests to compare psychological distress, we found no significant differences in outcome measures in either sample analyzed in our study. These findings contrast with prior literature indicating the negative psychological effect of burn injuries on certain locations in the body. Further research should explore whether larger burns (ie, < 5% TBSA) affecting critical areas of the body may be associated with psychological distress.

BACKGROUND: Patients with Medicare/Medicaid insurance receive metabolic and bariatric surgery (MBS) at lower rates than privately insured (PI) patients. Although studies on some surgical procedures report that Medicare/Medicaid insurance confers increased postoperative complication rates and a longer length of stay, less is known about these outcomes after MBS. Among often-feared postoperative complications are major adverse cardiovascular and cerebrovascular events (MACEs). Although these events are rare after MBS, they have a significant impact on morbidity and mortality. OBJECTIVES: This study aimed to examine the effect of insurance payor status on MACEs after MBS. SETTING: The Healthcare Cost and Utilization Project National Inpatient Sample (HCUP-NIS). METHODS: HCUP-NIS was queried for cases including sleeve gastrectomy or Roux-en-Y gastric bypass between 2012 and 2019. Bivariate associations between patient-level factors and MACEs were assessed via Rao-Scott χ2 tests. Adjusted and unadjusted risks of insurance payor status for MACEs were evaluated using logistic regression. RESULTS: Incidence of MACEs was higher in both Medicare (.75% versus .11%; P < .001) and Medicaid (.15% versus .11%; P < .001) groups than in the PI group. After adjustment for high-risk demographics, high-risk co-morbidities, socioeconomic variables, and hospital factors, insurance status of Medicare (odds ratio [OR]: 1.60, 95% confidence interval [CI]: 1.23, 2.07; P = .0026) or Medicaid (OR: 1.55, 95% CI: 1.12, 2.16; P = .0026) remained an independent risk factor for MACEs. CONCLUSIONS: Our findings underscore the significance of Medicaid/Medicare payor status as an independent predictor of postoperative MACEs in MBS. The results of this study can have a significant impact on deepening our understanding of socioeconomic and health system-related issues that can be targeted to improve outcomes in both MBS and other surgical specialties.
