A framework to improve retention of Black surgical trainees: A Society of Black Academic Surgeons white paper.

Attrition is high among surgical trainees, and six of ten trainees consider leaving their programs, with two ultimately leaving before completion of training. Given known historically and systemically rooted biases, Black surgical trainees are at high risk of attrition during residency training. With only 4.5% of all surgical trainees identifying as Black, underrepresentation among their peers can lend to misclassification of failure to assimilate as clinical incompetence. Furthermore, the disproportionate impact of ongoing socioeconomic crisis (e.g., COVID-19 pandemic, police brutality etc.) on Black trainees and their families confers additional challenges that may exacerbate attrition rates. Thus, attrition is a significant threat to medical workforce diversity and health equity. There is urgent need for surgical programs to develop proactive approaches to address attrition and the threat to the surgical workforce. In this Society of Black Academic Surgeons (SBAS) white paper, we provide a framework that promotes an open and inclusive environment conducive to the retention of Black surgical trainees, and continued progress towards attainment of health equity for racial and ethnic minorities in the United States.

Early-stage breast cancer treatment disparities in the Midsouth: Has anything changed?

BACKGROUND: We sought to determine if racial disparities in treatment and survival persist among patients with breast cancer in the Midsouth. METHODS: Patients with early-stage breast cancer were identified in the tumor registry of a large healthcare system in the Midsouth. Regression analyses were performed to determine how race was associated with receipt of treatment and mortality. RESULTS: Among 4605 patients, 38.8% were Black. Black patients were less likely to undergo surgery (OR = 0.71; 95%CI 0.53-0.97) and receive hormone therapy (OR = 0.81; 95%CI 0.69-0.95) than White patients, but more likely to receive radiation (OR = 1.20; 95%CI 1.08-1.40) and chemotherapy (OR = 1.36; 95%CI 1.16-1.61). Among Black patients, the risk of mortality was lower among those who underwent partial (OR = 0.25; 95%CI 0.12-0.51) or total (OR = 0.35; 95%CI 0.16-0.76) mastectomy and among those who received hormone therapy (OR = 0.62; 95%CI 0.40-0.97). CONCLUSION: There remains room for improvement in providing treatments that optimize survival among this patient population.

Impact of Social Determinants of Health on Outcomes Following Resection for Hepatocellular Carcinoma.

BACKGROUND: We sought to determine the impact of social determinants of health (SDoH) on outcomes of patients undergoing resection for hepatocellular carcinoma (HCC). PATIENTS AND METHODS: Patients with HCC in the National Cancer Database who underwent resection from 2009 to 2018 were identified. SDoH associated with length of stay (LOS), 30-day readmission, and 30-day mortality were analyzed using regression analyses adjusted for confounding variables. RESULTS: Among 9235 patients, the median age (range) was 65.0 (18-90) years, 72.1% were male, and 57.9% were White. A total of 3% were uninsured, 11.1% had Medicaid, 21% resided in regions with a median household income within the lowest quartile of the US population, and 27.0% resided in regions within the lowest quartile of education level. The odds for having longer LOS were lower among patients with the highest regional education level compared with those with the lowest level [odds ratio (OR) 0.86, 95% confidence interval (CI) 0.77-0.97]. The risk of readmission was lower among patients with Medicare (OR 0.52; 95% CI 0.33-0.81), Medicaid (OR 0.52; 95% CI 0.31-0.87), or private insurance (OR 0.56; 95% CI 0.35-0.88) compared with uninsured patients. Thirty-day overall mortality was less likely among patients with Medicare (OR 0.45; 95% CI 0.27-0.75), Medicaid (OR 0.53; 95% CI 0.30-0.93), or private insurance (OR 0.40; 95% CI 0.24-0.66), and among patients with high regional income (OR 0.58; 95% CI 0.44-0.77). CONCLUSIONS: Adjusted regression analyses identified SDoH that were associated with HCC outcomes. Increased awareness of how SDoH relate to outcomes may inform strategies that attempt to account for these associations and improve patient outcomes.

Recent Improvements in Racial Disparity in the Treatment of Hepatocellular Carcinoma: How Times Have Changed.

BACKGROUND: Race has been shown to impact receipt of and outcomes following hepatobiliary surgery. We sought to determine if racial disparities in the management of hepatocellular carcinoma persist. METHODS: Information on patients with hepatocellular carcinoma diagnosed between 2012 and 2016 was obtained from the Surveillance, Epidemiology, and End Results database. The sample was stratified by race/ethnicity, and associations between tumor characteristics, treatment, and survival were assessed. RESULTS: Of 33,672 patients, the mean age was 65 years, and 77% were male. By race, 17,150 (51%) were white, 4755 (14%) black, 6850 (20%) Hispanic, and 4917 (15%) Asian. When assessing the likelihood of treatment versus no treatment for tumors less than 5 cm, no difference was observed between whites and blacks in any year, but Hispanics were less likely than whites to receive treatment in most years. Asians were more likely to receive treatment every year. When assessing the likelihood of transplant versus surgical resection, blacks were less likely than whites to undergo transplant in all years except 2016. Hispanics were equally likely, while Asians were less likely to undergo transplant in all years. For years 2012 to 2016 collectively, Asians had better 5-year survival rates than other races after undergoing ablation and resection. No difference in the risk of death was observed among blacks, whites, or Hispanics after undergoing ablation, resection, or transplant. CONCLUSION: Racial disparities for blacks and Hispanics have improved. Although Asians were less likely to undergo transplant, they had better survival after undergoing resection or ablation.

Fatty liver: The metabolic syndrome increases major hepatectomy mortality.

BACKGROUND: As the obesity epidemic worsens, the prevalence of fatty liver disease has increased. However, minimal data exist on the impact of combined fatty liver and metabolic syndrome on hepatectomy outcomes. Therefore, the aim of this analysis is to measure the outcomes of patients who do and do not have a fatty liver undergoing hepatectomy in the presence and absence of the metabolic syndrome. METHODS: Patients with fatty and normal livers undergoing major hepatectomy (≥3 segments) were identified in the 2014 to 2018 American College of Surgeon National Surgical Quality Improvement Program database. Patients undergoing partial hepatectomy and those with missing liver texture data were excluded. Propensity matching was used and adjusted for multiple variables. A subgroup analysis stratified by the metabolic syndrome (body mass index ≥30 kg/m2, hypertension and diabetes) was performed. Demographics and outcomes were compared by χ2 and Mann-Whitney tests. RESULTS: Of 2,927 hepatectomies, 30% of patients (N = 863) had a fatty liver. The median body mass index was 28.6, and the metabolic syndrome was present in 6.3% of patients (N = 184). After propensity matching, 863 patients with fatty and 863 with normal livers were compared. Multiple outcomes were significantly worse in patients with fatty livers (P <.05), including serious morbidity (32% vs 24%), postoperative invasive biliary procedures (15% vs 10%), organ space infections (11% vs 7.8%), and pulmonary complications. Patients with fatty livers and the metabolic syndrome had significantly increased postoperative cardiac arrests, pulmonary embolisms, and mortality (P < .05). CONCLUSION: Fatty liver disease is associated with significantly worse outcomes after major hepatectomy. The metabolic syndrome confers an increased risk of postoperative mortality.

Treatment Patterns and Distance to Treatment Facility for Soft Tissue Sarcoma of the Extremity.

BACKGROUND: The impact that distance traveled to receive treatment has on treatments and outcomes among patients with soft tissue sarcoma (STS) of the extremity has yet to be thoroughly investigated. METHODS: Information on patients treated for STS of the extremity between 2006 and 2015 was obtained from the National Cancer Database. Patients were stratified into two groups based on median distance traveled to receive treatment. Chi-square tests assessed associations between categorical variables and distance to treatment. Kaplan-Meier survival estimates and Cox regression were used to estimate survival. RESULTS: The sample included 21,763 patients. The mean age was 59.3 y, 54.6% were men, and 83.2% were white. The median distance traveled to the treating facility was 15.6 miles. Compared with patients who traveled <15 miles, those who traveled ≥15 miles were more likely to have undifferentiated rather than well-differentiated tumors (odds ratio [OR], 1.23; 95% confidence interval [95% CI], 1.10-1.37), and stage II rather than stage I disease (OR, 1.14; 95% CI, 1.04-1.24). They were also more likely to undergo limb-sparing resection (OR, 1.58; 95% CI, 1.39-1.79) or amputation (OR, 1.72; 95% CI, 1.44-2.07) rather than no surgery and less likely to have positive margins (OR, 0.86; 95% CI, 0.79-0.93). There was no difference in the risk of death between patients who traveled ≥15 miles and those who did not (hazard ratio, 1.00; 95% CI, 0.94-1.07). CONCLUSIONS: Although clinical characteristics and treatments may differ based on distance traveled, survival appears equivalent. Further research into reasons why greater distance traveled is associated with more advanced disease, but comparable survival is warranted.

Pneumonectomy is necessary following delayed detection of pulmonary artery compromise.

It has been previously suggested that lung tissue remains viable without blood supply from the pulmonary artery (PA). However, our experience demonstrates otherwise. We present 2 cases of accidental left lower lobe PA occlusion during upper lobectomy causing ischaemic changes to the remaining lung tissue. Both patients became septic secondary to necrosis of infarcted lung and required completion pneumonectomy. Development of collateral circulation to bypass the occluded PA may occur but is often insufficient to support the affected lung tissue. Unless the patient is medically unfit, resection of the ischaemic lung should be undertaken.

In vivo measurement of esophageal hiatus surface area using MDCT: description of the methodology and clinical validation.

PURPOSE: Accurate estimation of esophageal hiatus surface area (HSA) prior to surgical repair of hiatal hernia is difficult. The ability to do so may assist with following progression of hiatal hernias, choosing the optimal surgical approach and post-surgical evaluation. We developed a method for measurement of HSA using multi-planar reconstruction (MPR) of multi-detector computed tomography (MDCT) scans and sought to validate our method using intra-operative HSA measurements. METHODS: Patients with thoracic or abdominal CT scans who were scheduled to undergo hiatal hernia repair were identified. A radiologist performed MPR of each MDCT scan to obtain the measured HSA (mHSA). Estimated HSA (eHSA) was obtained using intra-operative measurements of crura length and distance between crural edges. The association between eHSA and the corresponding mHSA was assessed using Pearson correlation. The intra-class correlation coefficient was calculated to assess both intra-observer and inter-observer agreement for the MDCT-MPR technique. RESULTS: Of 30 subjects included, 16 (53.3%) were female and the median age was 68.5 years. All patients underwent robotic-assisted laparoscopic hiatal hernia repair. The median HSA was 8.1 cm2 based on intra-operative measurements and 9.9 cm2 based on CT measurements. The correlation coefficient for eHSA and corresponding mHSA was 0.83 (p < 0.001). The intra-class correlation coefficient was 0.97 (p < 0.001) for intra-observer agreement and 0.97 (p < 0.001) for inter-observer agreement. CONCLUSION: We developed a MDCT-MPR technique that measures HSA in vivo. This technique is reproducible and can be used for pre-operative planning and post-operative follow-up of patients with symptomatic hiatal hernia.
