Metabolic and Bariatric Surgery Outcomes in African American Patients: a Single Institution Experience. Obes Surg 2024; 34:3246-3251. [PMID: 39052174 DOI: 10.1007/s11695-023-06823-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 08/17/2023] [Accepted: 09/15/2023] [Indexed: 07/27/2024]
Abstract
BACKGROUND The incidence of obesity in African Americans (AAs) is higher than in non-AA in the USA. Previous studies using large national databases report that AA patients have worse outcomes than non-AA patients. OBJECTIVES To assess perioperative outcomes among AA patients after MBS at a center of excellence (COE) that serves a large, diverse patient population. SETTING University Hospital METHODS: A retrospective analysis was performed on patients undergoing MBS between 2010 and 2020 at our two accredited MBSAQIP (Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program) COEs where the AA population makes up over 35% of the population. Preoperative variables were compared using unpaired t-test or chi-squared test where appropriate. Thirty-day outcomes were compared following propensity score matching (exact algorithm) of demographics and comorbidities. RESULTS Overall, 5742 patients (AA = 2058, 36%) had Roux-en-Y gastric bypass (AA = 1028, 26%) or sleeve gastrectomy (AA = 1030, 27%). AA patients were more often female (90.2% vs. 80.2%, p < 0.001) and had higher rates of hypertension (56.3% vs. 47.8%, p < 0.001), while non-AA patients had higher rates of hyperlipidemia (27.3% vs. 20.7%, p < 0.001) and obstructive sleep apnea (41.2% vs. 37.1%, p = 0.0024). Matched data showed that AA patients had higher rates of pulmonary embolism (PE) (0.3% vs. 0.1%, p = 0.020) and more emergency department visits (7.0% vs. 5.1%, p = 0.012) but no differences in mortality, readmission, reintervention, or reoperation rates. CONCLUSIONS In a diverse area, AA patients who underwent MBS had similar perioperative outcomes compared to non-AA patients except that they experienced higher rates of PE. They also experienced higher rates of emergency department visits but had similar readmission rates.

Abstract
Obesity is a common comorbidity among patients with heart failure with reduced ejection fraction (HFrEF) or heart failure with preserved ejection fraction (HFpEF), with the strongest pathophysiologic link of obesity being seen for HFpEF. Lifestyle measures are the cornerstone of weight loss management, but sustainability is a challenge, and there are limited efficacy data in the heart failure (HF) population. Bariatric surgery has moderate efficacy and safety data for patients with preoperative HF or left ventricular dysfunction and has been associated with reductions in HF hospitalizations and medium-term mortality. Antiobesity medications historically carried concerns for cardiovascular adverse effects, but the safety and weight loss efficacy seen in general population trials of glucagon-like peptide 1 (GLP-1) and gastric inhibitory polypeptide/GLP-1 agonists are highly encouraging. Although there are safety concerns regarding GLP-1 agonists in advanced HFrEF, trials of the GLP-1 agonist semaglutide for treatment of obesity have confirmed safety and efficacy in patients with HFpEF.

Abstract
For adults with advanced heart failure, class II/III obesity (body mass index ≥35 kg/m2) represents major challenges, and it is even considered a contraindication for heart transplantation (HT) at many centers. This has led to growing interest in preventing and treating obesity to help patients with advanced heart failure become HT candidates. Among all weight-loss strategies, bariatric surgery (BSx) has the greatest weight loss efficacy and has shown value in enabling select patients with left ventricular assist devices (LVADs) and obesity to lose sufficient weight to access HT. Nevertheless, both BSx and antiobesity medications warrant caution in the LVAD population. In this review, the authors describe and interpret the available published reports on the impact of obesity and weight-loss strategies for patients with LVADs from general and HT candidacy standpoints. The authors also provide an overview of the journey of LVAD recipients who undergo BSx and review major aspects of perioperative protocols.

Abstract
BACKGROUND The rates of postoperative complications can vary among specific patient populations. OBJECTIVES The aim of this study is to examine how gender, race, and ethnicity can affect short-term postoperative complications in bariatric surgery patients. SETTING United States. METHODS Patients who underwent bariatric surgery between the years 2016 and 2021 were included and stratified based on gender, race/ethnicity, and procedure type. The 30-day outcomes were assessed using Clavien-Dindo (CD) classification of III-V. Wilcoxon rank-sum test was performed to compare continuous variables among groups and Chi-squared test for categorical variables. Logistic regression was performed to examine the effects of gender, race/ethnicity on CD classification ≥ III complications by the procedure type. RESULTS A total of 975,642 bariatric surgery patients were included. Descriptive univariate analysis showed that CD ≥ III complications were higher among non-Hispanic blacks (NHB) and lowest in Hispanic patients, regardless of their gender, except in the duodenal switch DS group, where non-Hispanic whites (NHW) had the lowest complication rate. There was no difference between male and female patients with regards to postoperative complications, except in the sleeve gastrectomy (SG) group, where NHW males had more complications than NHW females. Sleeve gastrectomy showed the lowest complication rates followed by gastric bypass and DS in all groups. In multivariate logistic regression model, for both females and males NHBs had higher odds of postoperative complications compared to NHWs in sleeve gastrectomy (Female aOR:1.31, 95% CI: [1.23-1.40]; Male aOR:1.24, 95% CI: [1.08-1.43], P < .001) and gastric bypass (Female aOR:1.24, 95% CI: [1.16-1.33]; Male aOR:1.25, 95% CI: [1.06-1.48], P < .01). CONCLUSIONS Non-Hispanic Black patients are at a higher rate of developing CD ≥ III complications compared to non-Hispanic Whites after bariatric surgery. The male gender was not a significant risk factor for serious postoperative complications. Among the different types of bariatric procedures, sleeve gastrectomy has the lowest rates of severe complications, followed by gastric bypass and duodenal switch. These results highlight the significance of considering gender, race, ethnicity, and procedure type during preoperative evaluation, surgical planning, and postoperative care.

Abstract
INTRODUCTION Increasing emphasis on value-based healthcare has prompted both employers and healthcare organizations to develop innovative strategies to supply high quality care to patients. One such strategy is through the bundled care payment model (BCPM). Through this model, our institution partnered with employers from across the country to provide quality care for their members. Patients traveling greater than 2 h driving time from the bariatric center were considered "destination" patients. To properly care for our destination patients, our institution created a "destination bariatric program." We sought to investigate comparative outcomes for the first 100 patients who completed the program. We hypothesized that there would be no difference in patient outcomes or complications between destination and local patient groups undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB). METHODS AND PROCEDURES A retrospective cohort analysis of patients undergoing bariatric surgery at a MBSAQIP-accredited bariatric surgery center between May 2019 and October 2021 was conducted. Patients were divided into destination or local patient groups based on participation in the established destination surgery program. Patient demographics, perioperative clinical outcomes, and complications were compared and statistically analyzed using two-sample t-tests, Chi-square tests, Fisher's exact tests, and univariate logistic regressions. RESULTS This study identified 296 patients, which consisted of destination (n = 110) and local (n = 186) patient cohorts. Patients in the destination group had higher rates of diabetes mellitus (29.1% vs 24.2%, p = 0.029), but otherwise cohorts had similar basic demographics and comorbidities. Outcomes revealed no statistically significant associations between patient cohort (destination versus local) and ED admission (p = 0.305), hospital readmission (p = 0.893), surgical reintervention (p = 0.974), endoscopic-reintervention (p = 0.714), and patient complications in the postoperative period (30 days). CONCLUSION Participation in destination care programs for bariatric surgery was found to be both safe and feasible. These destination programs represent an opportunity to provide a broader patient population access to complex surgical care.

Abstract
BACKGROUND Acute kidney injury (AKI) after surgery increases long-term risk of kidney dysfunction. The major risk factor for AKI after bariatric surgery is having preoperative renal insufficiency. Little is known about the outcomes and risk factors for developing AKI in patients undergoing bariatric surgery with normal renal function. OBJECTIVE We aimed to describe factors that may increase risk of AKI after primary bariatric surgery in patients without history of kidney disease. SETTING Academic hospital, United States. METHODS We performed a retrospective analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program data registry for patients aged ≥18 years undergoing laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass (LRYGB) from 2015 to 2019. Patients with diagnosis of chronic kidney disease were excluded. The primary outcome was incidence of AKI. Secondary outcomes included 30-day complications, readmissions, reoperations, and mortality. Univariate and multivariate analyses were performed to identify differences between patients with and without AKI. RESULTS A total of 747,926 patients were included in our analysis (laparoscopic sleeve gastrectomy = 73.1%, LRYGB = 26.8%). Mean age was 44.40 ± 11.94 years, with female predominance (79.7%). AKI occurred in 446 patients (.05%). Patients with postoperative AKI had higher rates of complications, readmissions, reoperations, and mortality. Significant predictors of AKI were male sex, history of venous thromboembolism, hypertension, limitation for ambulation, and LRYGB. High albumin levels and White race were protective factors. CONCLUSIONS New-onset AKI was associated with adverse 30-day outcomes in patients undergoing bariatric surgery. Male sex, venous thromboembolism, hypertension, limited ambulation, and LRYGB were independent predictors of AKI. Prospective studies are needed to better describe these results.

Abstract
PURPOSE Eighty percent of patients who undergo metabolic-bariatric surgery self-identify as female. It is unclear why there is a disparate use of metabolic-bariatric surgery by men compared to women given the widely accepted safety of weight loss surgical procedures. One possible explanation is that post-operative outcomes of metabolic-bariatric surgery have been shown to be worse for men compared to women in prior studies. The purpose of this study was to characterize the impact of gender on outcomes of metabolic-bariatric surgery using the most recent MBSAQIP data registry from 2017-2021. MATERIALS AND METHODS Data entered into the MBSAQIP registry from 2017-2021 for patients who underwent primary metabolic-bariatric surgery procedures was identified. The data was then matched for multiple pre-operative factors and comorbidities, and outcomes were assessed and compared for men and women. RESULTS No significant difference was observed in anastomotic leak, wound complications, and bleeding between men and women. However, men were at 0.15% (p < 0.01) higher risk of major complications (encompassing unplanned ICU admission, deep organ space infection, unplanned intubation, bleeding, anastomotic leak, sepsis, pneumonia, myocardial infarction, cardiac arrest, cerebrovascular accident, pulmonary embolism, reoperation, and death) compared to women. While men had higher major complications compared to women for SG, there was no significant difference between the two cohorts for RYGB, BPD and LAGB. CONCLUSION While there are some differences in outcomes between male and female patients, the difference is modest. Male gender should not be considered a high-risk factor for all bariatric procedures and cannot explain the difference in utilization of metabolic-bariatric surgery by men compared to women.

Abstract
BACKGROUND Metabolic and bariatric surgery (MBS) remains a safe and effective treatment for patients with severe obesity. Recent studies have highlighted racial disparities in perioperative outcomes, including up to a twofold higher mortality rate in non-Hispanic black (NHB) (vs. non-Hispanic white (NHW)) patients. Causality for these disparate outcomes remains unclear and largely unexplored. OBJECTIVE Our study aim was to determine reasons for mortality among racial and ethnic cohorts and MBS patients. SETTING Academic Hospital. METHODS Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) cases were identified using the 2015 to 2018 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Project (MBSAQIP) database using current procedural (CPT) codes 43,664, 43,645, and 43,775. Multivariate regression analyses were performed to determine independent predictors of overall and bariatric-related mortality. Reasons for mortality were identified and compared between racial and ethnic cohorts. RESULTS Of 650,903 RYGB and SG cases, 512,041 were included in our analysis (73% SG). For the entire cohort, all-cause and bariatric-related mortality rates were 0.095% and 0.05%, respectively. Age, male gender, ASA 4, functional status, therapeutic anticoagulation, smoking, COPD, and RYGB were independently associated with both overall and bariatric-related mortality. NHB had increased odds (2.13, p < 0.001) of bariatric-related mortality. Compared to NHW patients (13.3%), venous thromboembolic (VTE) complication was the most common reason for overall mortality in NHB (27.8%) and Hispanic (25%) patients (p < 0.001). VTE-related mortality directly associated with the bariatric procedure was also higher in NHB (34.6%) and Hispanic (33.3%) (vs. NHW 21.0%) patients (p 0.05). When stratified by procedure, mortality causes in RYGB cases were similar between racial and ethnic cohorts. In the SG cohort, the proportion of VTE-related mortality varied significantly (p 0.043) between NHB (39.2%), Hispanic 40.0%, and NHW (20.5%) patients. CONCLUSION There are racial and ethnic differences in causes of mortality following bariatric surgery. The predominant cause of overall and bariatric-related mortality in NHB bariatric surgery patients is postoperative venous thromboembolism. More granular MBSAQIP data capture is needed to determine the role of patient risk versus practice patterns in these disparate outcomes.

Abstract
BACKGROUND Sleeve gastrectomy (SG) frequently requires conversion to Roux-en-Y gastric bypass (RYGB) due to gastroesophageal reflux disease (GERD) or weight recurrence. Current evidence evaluating the safety of conversion from SG to RYGB and its indications is limited to single centers. METHODS The objective was to determine the rate of serious complications and mortality of conversion of SG to RYGB (SG-RYGB) compared to primary RYGB (P-RYGB). This was a retrospective analysis of the MBSAQIP database which includes 30-day outcomes. Individuals undergoing P-RYGB or SG-RYGB were included. Multivariable logistic regression was performed to determine if revisional surgery was an independent predictor of serious complications or mortality. RESULTS In 2020 and 2021, 84,543 (86.3%) patients underwent P-RYGB and 13,432 (13.7%) underwent SG-RYGB. SG-RYGB cohort had lower body mass index, lower rates of diabetes and hypertension, and higher rates of GERD. GERD was the most common indication for revision (55.3%) followed by weight regain (24.4%) and inadequate weight loss (12.7%). SG-RYGB had longer operative times (145 vs. 125 min, p < 0.001) and a higher rate of serious complications (7.2 vs. 5.0%, p < 0.001). This included higher rates of anastomotic leak (0.5 vs. 0.4%, p = 0.002), bleeding (2.0 vs. 1.6%, p < 0.001), and reoperation (3.0 vs. 1.9%, p < 0.001) but not death (0.1 vs. 0.1%, p = 0.385). On multivariable analysis, SG-RYGB was independently predictive of serious complications (OR 1.21, 95%CI 1.12 to 1.32, p < 0.001) but not mortality (p = 0.316). CONCLUSIONS While SG-RYGB is safe with a low complication rate, SG-RYGB was associated with a higher rate of serious complications compared to P-RYGB.

Atrial dysrhythmias are independent predictors of serious complications and 30-day mortality after elective bariatric surgery: a retrospective study of 731,981 patients. Surg Obes Relat Dis 2023; 19:204-211. [PMID: 36257894 DOI: 10.1016/j.soard.2022.08.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/06/2022] [Revised: 07/25/2022] [Accepted: 08/30/2022] [Indexed: 10/14/2022]
Abstract
OBJECTIVES The objectives of this study were to characterize the prevalence of atrial dysrhythmias for elective bariatric surgery patients and to explore their impact on postoperative outcomes. SETTING Data was extracted from the North American Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2015 to 2019. METHODS All primary Roux-en-Y gastric bypass and sleeve gastrectomy procedures were included. Patients with atrial dysrhythmias (ADs) were identified as patients coded as receiving preoperative therapeutic anticoagulation without a prior history of deep vein thrombosis, venous thromboembolism, pulmonary embolism, or other conditions requiring anticoagulation. Multivariable logistic regression analysis was used to determine the impact of preoperative ADs on postoperative complications and 30-day mortality. RESULTS We evaluated 731,981 patients, of whom 13,591 (1.9%) had preoperative ADs. Patients with ADs were more likely to be older, have a higher body mass index, and be male. Metabolic co-morbidities also were more common in those with ADs, as demonstrated by the higher rates of medication use and insulin-dependent diabetes, hypertension, dyslipidemia, and sleep apnea. After adjusting for co-morbidities using multivariable logistic regression, AD was the single greatest independent predictor of serious complications and 30-day mortality. CONCLUSIONS ADs were observed in approximately 2% of MBSAQIP patients. ADs are among the greatest independent predictors of serious complications and mortality, suggesting that these patients are associated with a higher perioperative risk profile warranting further optimization.

Abstract
PURPOSE OF REVIEW Rates of obesity and associated comorbidities are higher among Black and Latino adults compared to white adults. We sought to provide an overview of both structural and individual factors contributing to obesity inequities and synthesize available evidence regarding treatment outcomes in Black and Latino adults, with an eye towards informing future directions. RECENT FINDINGS Obesity disparities are influenced by myriad systemic issues, yet the vast majority of interventions target individual-level factors only, and most behavioral treatments fail to target drivers beyond eating and physical activity. Extant treatments are not equally accessible, affordable, or effective among Black and Latino adults compared with white counterparts. Asset-based, culturally relevant interventions that target the root causes of obesity and address intersectional stress-designed in partnership with intended beneficiaries-are urgently needed. Treatment trials must improve enrollment of Black and Latino adults and report treatment outcomes by race and ethnicity.

Abstract
INTRODUCTION With expansion of bariatric surgery indications to include Asian patients with diabetes and body mass index (BMI) ≥ 27.5, or BMI ≥ 32.5, it is important to characterize Asian patient population undergoing bariatric surgery and assess their postoperative outcomes. METHODS This retrospective study analyzed the 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. All patients undergoing Roux-en-Y gastric bypass (RYGB) and laparoscopic sleeve gastrectomy (LSG) who self-reported as Asian or White race were included. The primary outcomes were to characterize the Asian race population in North American and to identify if Asian race was associated with serious complications or mortality at 30 days. RESULTS Overall, 594,837 patients met inclusion, with 4229 self-reporting Asian racial status. Patients of Asian race were younger (41.8 vs 45.5 years, p < 0.001) and had a lower BMI (42.8 vs 44.7 kg/m2 p < 0.001) than White patients. They were also more likely to have insulin dependent diabetes (10.9% vs 8.2%, p < 0.001), have received prior cardiac surgery (10.0% vs 1.2% p < 0.001), and suffer from renal insufficiency (1.0% vs 0.5%, p < 0.001). There were no significant differences between rates of RYGB (28.3% vs 28.9%, p = 0.4) and mean operative duration (87.7 vs 87.5 min, p = 0.7). Additionally, there were no differences in 30 day outcomes including leak (0.5% vs 0.5%, p = 0.625), bleeding (1.2% vs 1.0%, p = 0.1), serious complications (3.4% vs 3.5%, p = 0.6), or mortality (0.1% vs 0.1%, p = 0.7) and after confounder control, Asian race was not independently associated with serious complications (OR 1.0, CI 0.9-1.2, p = 0.7), or mortality (OR 1.1, CI 0.3-3.3, p = 0.1). CONCLUSIONS Despite the increased metabolic burden of Asian patients, no differences in 30-day outcomes compared to White patients occurs. This data supports evidence suggesting these patients may safely undergo bariatric surgery independent of their increased metabolic burden.

Surg Endosc 2023; 37:564-570. [PMID: 35508664 PMCID: PMC9633573 DOI: 10.1007/s00464-022-09292-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2021] [Accepted: 04/18/2022] [Indexed: 01/18/2023]
Abstract
BACKGROUND Although bariatric surgery is the most effective treatment for obesity and weight-related comorbid diseases, utilization rates are disproportionately low among non-white patients. We sought to understand if variation in baseline characteristics or access to care exists between white and non-white patients. METHODS Using a statewide bariatric-specific data registry, we evaluated all patients who underwent bariatric surgery between 2006 and 2020 and completed a preoperative baseline questionnaire, which included a question about self-identification of race. Patient characteristics, co-morbidities, and time from initial preoperative clinic evaluation to date of surgery were compared among racial groups. RESULTS A total of 73,141 patients met inclusion criteria with 18,741 (25.5%) self-identified as non-white. These included Black/African American (n = 11,904), Hispanic (n = 3448), Asian (n = 121), Native Hawaiian/Pacific Islander (n = 41), Middle Eastern (n = 164), Multiple (n = 2047) and other (n = 608). Non-white males were the least represented group, accounting for only 4% of all bariatric cases performed. Non-white patients were more likely to be younger (43.0 years vs. 46.6 years, p < 0.0001), disabled (16% vs. 11.4%, p < 0.0001) and have Medicaid (8.4% vs. 3.8%, p < 0.0001) when compared to white patients, despite having higher rates of college education (78.0% vs. 76.6, p < 0.0001). In addition, median time from initial evaluation to surgery was also longer among non-white patients (157 days vs. 127 days, p < 0.0001), despite having higher rates of patients with a body mass index above 50 kg/m2 (39.0% vs. 33.2%, p < 0.0001). CONCLUSIONS Non-white patients undergoing bariatric surgery represent an extremely diverse group of patients with more socioeconomic disadvantages and longer wait times when compared to white patients despite presenting with higher rates of severe obesity. Current guidelines and referral patterns for bariatric surgery may not be equitable and need further examination when considering the management of obesity within diverse populations to reduce disparities in care-of which non-white males are particularly at risk.

Method of venous thromboembolism prophylaxis is not a predictor of pulmonary embolus following elective bariatric surgery: a retrospective cohort study of 135,409 patients. Surg Obes Relat Dis 2022; 18:1378-1384. [PMID: 36184276 DOI: 10.1016/j.soard.2022.08.015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2022] [Revised: 06/27/2022] [Accepted: 08/30/2022] [Indexed: 01/12/2023]
Abstract
BACKGROUND Patients with obesity are at increased risk of pulmonary embolus (PE), a risk that increases perioperatively and is challenging to manage. OBJECTIVE An analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database was performed to determine predictors of PE in patients undergoing elective bariatric surgery. SETTING North American accredited bariatric surgery institutions included in the MBSAQIP database from 2020-2021. METHODS We extracted data from the MBSAQIP database (2020-2021) on patients who underwent elective Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG). Data were extracted on patient co-morbidities, race, prior history of deep vein thrombosis (DVT), and type of DVT prophylaxis. A multivariate logistic regression model was developed to determine predictors of PE and impact of PE on 30-day serious complications and mortality. RESULTS In the MBSAQIP database, a total of 135,409 patients underwent SG or RYGB from 2020 to 2021. PE was reported in 194 patients (.14%). Prior history of DVT (odds ratio [OR] = 3.28; 95% confidence interval [CI]: 1.85-5.83; P < .0001), Black race (OR = 3.03; 95% CI: 2.22-4.13; P < .0001), gastroesophageal reflux disease (OR = 1.51; 95% CI: 1.11-2.04; P = .008), higher body mass index (OR = 1.11; 95% CI: 1.01-1.20; P = .023), male sex (OR = 1.76; 95% CI: 1.26-2.45; P = .001), and older age (OR = 1.27; 95% CI: 1.10-1.46; P = .001) were associated with increased odds of PE. Chronic obstructive pulmonary disease, sleep apnea, and hypertension were not significant predictors of PE (P > .05). Neither combined mechanical and pharmacologic DVT prophylaxis nor pharmacologic prophylaxis alone was a significant predictor of PE (P > .05). CONCLUSION Prior history of DVT is the strongest predictor of PE after bariatric surgery. African American race, male sex, and gastroesophageal reflux disease are additional risk factors. Method of venous thromboembolism prophylaxis was not identified as significant predictor of PE. Further, studies on the evaluation and optimization of venous thromboembolism prophylaxis are required.

Abstract
Background There have been a multitude of studies attempting to identify the relationship between gender and postoperative outcomes; however, few studies have examined how this relationship may affect outcomes after anterior lumbar interbody fusion (ALIF) surgery. We aim to better characterize the impact that self-reported gender may have on patient reported outcome measures (PROMs) and achievement rates of minimum clinically important difference (MCID) after ALIF. Methods A retrospective database of a single spine surgeon was searched for patients who had undergone single-level ALIF. Indications for surgery including acute trauma, infection, or malignancy were excluded. The population was separated into cohorts by self-reported gender, female or male. PROMs were recorded and compared within groups to their preoperative baselines and between groups. MCID achievement rate was compared between groups. Results 140 patients were identified for this study, with 68 patients self-identifying as female gender. The male gender cohort was found to have a significantly greater prevalence of hypertension (p = 0.018). Both cohorts showed significant improvement during at least one or more postoperative time points for each evaluated outcome measure (p ≤ 0.048, all). No significant difference in mean PROM scores was noted between cohorts at any time point for any measured outcome. The female gender cohort had significantly greater MCID achievement rates for visual acuity scale (VAS) back pain overall and at the 6-month time point (p ≤ 0.043, both). The female gender cohort also had significantly greater achievement of MCID at the 1-year time point for VAS leg pain (p = 0.017). Conclusion Both female and male gender cohorts demonstrated significant improvement in all outcomes measured at one or more postoperative time points. Postoperative outcomes did not differ by gender. MCID achievement was more common in female patients. Female patients may experience more tangible clinical improvement after ALIF compared to male patients.

Abstract
Importance Bariatric surgery is the most effective treatment for severe obesity; yet it is unclear whether the long-term safety and comparative effectiveness of these operations differ across racial and ethnic groups. Objective To compare outcomes of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) across racial and ethnic groups in the National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study. Design, Setting, and Participants This was a retrospective, observational, comparative effectiveness cohort study that comprised 25 health care systems in the PCORnet Bariatric Study. Patients were adults and adolescents aged 12 to 79 years who underwent a primary (first nonrevisional) RYGB or SG operation between January 1, 2005, and September 30, 2015, at participating health systems. Patient race and ethnicity included Black, Hispanic, White, other, and unrecorded. Data were analyzed from July 1, 2021, to January 17, 2022. Exposure RYGB or SG. Outcomes Percentage total weight loss (%TWL); type 2 diabetes remission, relapse, and change in hemoglobin A1c (HbA1c) level; and postsurgical safety and utilization outcomes (operations, interventions, revisions/conversions, endoscopy, hospitalizations, mortality, 30-day major adverse events) at 1, 3, and 5 years after surgery. Results A total of 36 871 patients (mean [SE] age, 45.0 [11.7] years; 29 746 female patients [81%]) were included in the weight analysis. Patients identified with the following race and ethnic categories: 6891 Black (19%), 8756 Hispanic (24%), 19 645 White (53%), 826 other (2%), and 783 unrecorded (2%). Weight loss and mean reductions in HbA1c level were larger for RYGB than SG in all years for Black, Hispanic, and White patients (difference in 5-year weight loss: Black, -7.6%; 95% CI, -8.0 to -7.1; P < .001; Hispanic, -6.2%; 95% CI, -6.6 to -5.9; P < .001; White, -5.9%; 95% CI, -6.3 to -5.7; P < .001; difference in change in year 5 HbA1c level: Black, -0.29; 95% CI, -0.51 to -0.08; P = .009; Hispanic, -0.45; 95% CI, -0.61 to -0.29; P < .001; and White, -0.25; 95% CI, -0.40 to -0.11; P = .001.) The magnitude of these differences was small among racial and ethnic groups (1%-3% of %TWL). Black and Hispanic patients had higher risk of hospitalization when they had RYGB compared with SG (hazard ratio [HR], 1.45; 95% CI, 1.17-1.79; P = .001 and 1.48; 95% CI, 1.22-1.79; P < .001, respectively). Hispanic patients had greater risk of all-cause mortality (HR, 2.41; 95% CI, 1.24-4.70; P = .01) and higher odds of a 30-day major adverse event (odds ratio, 1.92; 95% CI, 1.38-2.68; P < .001) for RYGB compared with SG. There was no interaction between race and ethnicity and operation type for diabetes remission and relapse. Conclusions and Relevance Variability of the comparative effectiveness of operations for %TWL and HbA1c level across race and ethnicity was clinically small; however, differences in safety and utilization outcomes were clinically and statistically significant for Black and Hispanic patients who had RYGB compared with SG. These findings can inform shared decision-making regarding bariatric operation choice for different racial and ethnic groups of patients.

Abstract
BACKGROUND There is a paucity of data comparing 30-day morbidity and mortality of sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and one anastomosis gastric bypass (OAGB). This study aimed to compare the 30-day safety of SG, RYGB, and OAGB in propensity score-matched cohorts. MATERIALS AND METHODS This analysis utilised data collected from the GENEVA study which was a multicentre observational cohort study of bariatric and metabolic surgery (BMS) in 185 centres across 42 countries between 01/05/2022 and 31/10/2020 during the Coronavirus Disease-2019 (COVID-19) pandemic. 30-day complications were categorised according to the Clavien-Dindo classification. Patients receiving SG, RYGB, or OAGB were propensity-matched according to baseline characteristics and 30-day complications were compared between groups. RESULTS In total, 6770 patients (SG 3983; OAGB 702; RYGB 2085) were included in this analysis. Prior to matching, RYGB was associated with highest 30-day complication rate (SG 5.8%; OAGB 7.5%; RYGB 8.0% (p = 0.006)). On multivariate regression modelling, Insulin-dependent type 2 diabetes mellitus and hypercholesterolaemia were associated with increased 30-day complications. Being a non-smoker was associated with reduced complication rates. When compared to SG as a reference category, RYGB, but not OAGB, was associated with an increased rate of 30-day complications. A total of 702 pairs of SG and OAGB were propensity score-matched. The complication rate in the SG group was 7.3% (n = 51) as compared to 7.5% (n = 53) in the OAGB group (p = 0.68). Similarly, 2085 pairs of SG and RYGB were propensity score-matched. The complication rate in the SG group was 6.1% (n = 127) as compared to 7.9% (n = 166) in the RYGB group (p = 0.09). And, 702 pairs of OAGB and RYGB were matched. The complication rate in both groups was the same at 7.5 % (n = 53; p = 0.07). CONCLUSIONS This global study found no significant difference in the 30-day morbidity and mortality of SG, RYGB, and OAGB in propensity score-matched cohorts.

[PMID: 34789421 DOI: 10.1016/j.soard.2021.10.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 09/23/2021] [Accepted: 10/21/2021] [Indexed: 12/17/2022]
Abstract
BACKGROUND Large-scale analyses stratifying bariatric surgery readmissions by urgency are lacking. OBJECTIVES Identify predictors of urgent/nonurgent readmission among "ideal" bariatric candidates, using a national registry. SETTING Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) national database. METHODS We extracted an "ideal" patient cohort from the 2015-2018 Metabolic and Bariatric Surgery Accreditation Quality Improvement Program (MBSAQIP) registry, characterized by only typical weight-related comorbidities (hypertension [HTN], obstructive sleep apnea [OSA], gastroesophageal reflux disease [GERD], and diabetes (insulin-dependent diabetes mellitus [IDDM] and non-insulin-dependent diabetes mellitus [NIDDM]) undergoing primary bariatric surgery with an uneventful postoperative course. Readmissions were classified as "urgent" (UR; e.g., leak, obstruction, bleeding) or "nonurgent" (NUR; e.g., dehydration, nonspecific abdominal pain). χ2 or t test analyses were used for bivariate significance testing. Multivariate logistic regression models were constructed to assess independent predictors of readmission. RESULTS The cohort (N = 292,547) comprised 38.5% of all MBSAQIP patients (mean age [standard deviation] = 43.2 [11.7]; body mass index [BMI] = 44.9 [6.6]; 81% female; 62% White, 17% Black, 14% Hispanic). Total readmission rates were 2.75% (n = 8046) and decreased from 2015-2018 (3.00%-2.63%; P < .001). Independent predictors of readmissions included Roux-en-Y gastric bypass (RYGB) (odds ratio [OR] = 1.97, p < .001), Black (OR = 1.46, P < .001) and Hispanic race (OR = 1.14, P < .001), GERD (OR = 1.27, P < .001), HTN (OR = 1.08, P = .003), and IDDM (OR = 1.39, P < .001). NUR and UR readmission rates were 1.27% (n = 3702) and 1.06% (n = 3090), respectively. NURs decreased over time (1.42%-1.16%, P < .001), with no change in Urs (1.01%-1.06%, P = .51); this trend persisted in multivariate analysis (2017: NUR OR = .85, P < .001; 2018: NUR OR = .82, p < .001). Independent predictors of both URs and NURs included Black (NUR OR = 1.71, p < .001; UR OR = 1.27, p < .001) and Hispanic (NUR OR = 1.15, P < .001; UR OR = 1.19, P < .001) race, RYGB (NUR OR = 1.84, P < .001; UR OR = 2.34, P < .001), and GERD (NUR OR = 1.39, p < .001; UR OR = 1.17, P < .001). Female sex (NUR OR = 1.64, P < .001), age (NUR OR = .98, P < .001), HTN (NUR OR = 1.22, P < .001), and IDDM (NUR OR = 1.41, P < .001) predicted NURs, while higher BMI (UR OR = 1.01, P < .001), and OSA (UR OR = 1.10, P = .02) predicted URs. CONCLUSION Readmission rates for "ideal" bariatric patients improved over time, driven by reductions in non-urgent etiologies. Racial disparities persist for both urgent and non-urgent causes of readmission.

Racial disparities in complications and mortality after bariatric surgery: A systematic review. Am J Surg 2021; 223:863-878. [PMID: 34389157 DOI: 10.1016/j.amjsurg.2021.07.026] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2021] [Revised: 06/23/2021] [Accepted: 07/17/2021] [Indexed: 01/10/2023]
Abstract
BACKGROUND Studies have shown racial discrepancies in the rates of postoperative adverse events following bariatric surgery (BS). We aim to systematically review the literature examining racial disparities in postoperative adverse events. METHODS PubMed, Embase, and SCOPUS databases were searched for studies that reported race, postoperative adverse events and/or length of stay. RESULTS Thirty-five studies were included. Most compared Black and White patients using standardized databases. Racial/ethnic terminology varied. The majority found increased 30-day mortality and morbidity and length of stay in Black relative to White patients. Differences between White and Hipanic patients were mostly non-significant in these outcomes. CONCLUSIONS Black patients may experience higher rates of adverse events than White patients within 30 days following bariatric surgery. Given the limitations in the large multicenter databases, explanations for this disparity were limited. Future research would benefit from longer-term studies that include more races and ethnicities and consider socioeconomic factors.

Abstract
IMPORTANCE Bariatric surgical weight loss is associated with reduced cardiovascular mortality; however, the mechanisms underlying this association are incompletely understood. OBJECTIVES To identify variables associated with vascular remodeling after bariatric surgery and to examine how sex, race, and metabolic status are associated with microvascular and macrovascular outcomes. DESIGN, SETTING, AND PARTICIPANTS This population-based longitudinal cohort included 307 individuals who underwent bariatric surgery. Participants were enrolled in the bariatric weight loss program at Boston Medical Center, a large, multi-ethnic urban hospital, with presurgical and postsurgical assessments. Data were collected from December 11, 2001 to August 27, 2019. Data were analyzed in September 2019. EXPOSURE Bariatric surgery. MAIN OUTCOMES AND MEASURES Flow-mediated dilation (FMD) and reactive hyperemia (RH) (as measures of macrovascular and microvascular function, respectively) and clinical variables were measured preoperatively at baseline and at least once postoperatively within 12 months of the bariatric intervention. RESULTS A total of 307 participants with obesity (mean [SD] age, 42 [12] years; 246 [80%] women; 199 [65%] White; mean [SD] body mass index, 46 [8]) were enrolled in this study. Bariatric surgery was associated with significant weight loss and improved macrovascular and microvascular function across subgroups of sex, race, and traditional metabolic syndrome (mean [SD] pre- vs postsurgery weight: 126 [25] kg vs 104 [25] kg; P < .001; mean [SD] pre- vs postsurgery FMD: 9.1% [5.3] vs 10.2% [5.1]; P < .001; mean [SD] pre- vs postsurgery RH: 764% [400] vs 923% [412]; P < .001). Factors associated with change in vascular phenotype correlated most strongly with adiposity markers and several metabolic variables depending on vascular territory (eg, association of weight change with change in RH: estimate, -3.2; 95% CI, -4.7 to -1.8; association of hemoglobin A1c with change in FMD: estimate, -0.5; 95% CI, -0.95 to -0.05). While changes in macrovascular function among individuals with metabolically healthy obesity were not observed, the addition of biomarker assessment using high-sensitivity C-reactive protein plasma levels greater than 2 mg/dL identified participants with seemingly metabolically healthy obesity who had low-grade inflammation and achieved microvascular benefit from weight loss surgery. CONCLUSIONS AND RELEVANCE The findings of this study suggest that bariatric intervention is associated with weight loss and favorable remodeling of the vasculature among a wide range of individuals with cardiovascular risk. Moreover, differences in arterial responses to weight loss surgery by metabolic status were identified, underscoring heterogeneity in physiological responses to adiposity change and potential activation of distinct pathological pathways in clinical subgroups. As such, individuals with metabolically healthy obesity represent a mixed population that may benefit from more refined phenotypic classification.

Surg Obes Relat Dis 2021; 17:1249-1255. [PMID: 33985924 DOI: 10.1016/j.soard.2021.04.011] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2020] [Revised: 04/01/2021] [Accepted: 04/08/2021] [Indexed: 12/25/2022]
Abstract
BACKGROUND Racial disparities in postsurgical complications are often presumed to be due to a higher preoperative co-morbidity burden among patients of black race, although being relatively healthy is not a prerequisite for a complication-free postoperative course. OBJECTIVES To examine the association of race with short-term postbariatric surgery complications in seemingly healthy patients. SETTINGS Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program database (2015-2018). METHODS We studied a relatively healthy (American Society of Anesthesiologists physical status 1 or 2), propensity score-matched cohort of adult non-Hispanic black and non-Hispanic white bariatric surgery patients. We compared the risk-adjusted incidences of postoperative complications, serious adverse events, and measures of postoperative resource utilization across racial groups. RESULTS We identified 44,090 matched pairs of relatively healthy black and white bariatric surgery patients. Patients of black race were 72% more likely than those of white race to develop 1 or more postoperative complications (.7% versus .4%, respectively; odds ratio [OR], 1.72; 95% confidence interval [CI], 1.32-2.24; P < .01). Measures of postbariatric resource utilization were significantly higher in patients of black race than those of white race, including unplanned reoperations (1.3% versus 1.0%, respectively; OR, 1.28; 95% CI, 1.07-1.52; P = .01), unplanned readmissions (4.5% versus 3.0%, respectively; OR, 1.53; 95% CI, 1.38-1.69; P < .01), unplanned interventions (1.6% versus 1.2%, respectively; OR, 1.36; 95% CI, 1.16-1.60; P < .01), and extended hospital lengths of stay (51.2% versus 42.7%, respectively; OR, 1.41; 95% CI, 1.36-1.46; P < .01). CONCLUSION Even among relatively healthy patients, race appears to be an important determinant of postbariatric surgery complications and resource utilization. Research and interventions aimed at narrowing the racial disparities in bariatric surgery outcomes may need to broaden the focus beyond the racial variation in the preoperative co-morbidity burden.

Implications of Technical Factors in Development of Early Sleeve Stenosis After Laparoscopic Sleeve Gastrectomy: an Analysis Using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program Database. Obes Surg 2021; 31:2373-2379. [PMID: 33604864 DOI: 10.1007/s11695-021-05288-y] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/12/2020] [Revised: 02/01/2021] [Accepted: 02/09/2021] [Indexed: 12/11/2022]
Abstract
PURPOSE Laparoscopic sleeve gastrectomy (LSG) is the most commonly performed bariatric procedure worldwide. Sleeve stenosis (SS) is a rare complication of LSG and is associated with significant morbidity and economic burden. The objective of this study was to determine the prevalence and impact of early SS and identify technical factors which may predict its development. MATERIALS AND METHODS Data was extracted from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2015 to 2018. Patients undergoing primary LSG were included, while patients undergoing revisional bariatric surgery were excluded. A multivariable logistic regression analysis was performed to identify technical factors associated with SS. RESULTS A total of 389,839 patients (79.4% female) were included with a mean age of 44.2 ± 12.0 years and mean body mass index of 45.1 ± 7.8 kg/m2. SS was rare, occurring in only 0.09% (n=345) of patients within 30 days of the operation. Following multivariable analysis, technical factors associated with early SS included prolonged operative time > 60 min (OR 1.32, 95% CI 1.17-1.48, p < 0.001) and a shorter PD (OR 0.864, 95% CI 0.784-0.951, p=0.003). For every 1-cm increase in PD, the odds of SS decreased by 13.6%. CONCLUSION Overall, early SS is a rare complication, affecting only 0.09% of patients undergoing primary LSG. Technical factors associated with 30-day SS included PD and operative time. Though current guidelines suggest a PD as short as 2 cm, our findings suggest this may be associated with an increased risk of early postoperative SS.

Abstract
BACKGROUND Severe obesity is increasingly common in youth and young adults, but outcomes following bariatric surgery remain largely unknown. The purpose of this study was to examine the trends, clinical characteristics, and postoperative outcomes of youth who underwent bariatric surgery. METHODS This retrospective cohort study was conducted using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) data registry from 2015 to 2018 inclusive. All youth and young adults aged 15-24 who underwent elective sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) were included. Bivariate analysis of trends, clinical characteristics, and postoperative outcomes was performed using Chi-squared tests for categorical variables and independent two sample t test for continuous variables. Multivariable logistic regression modeling was used to determine patient and operative factors predictive of serious complications. RESULTS A total of 21,592 youth and young adults underwent bariatric surgery during the study time frame, representing 3.7% of total cases (n = 583,567) within the MBSAQIP. The cohort had a mean age of 21.5 ± 2.0 years and a mean BMI of 47.2 ± 8.0 kg/m2 and were predominantly female (84%). A relatively constant number of youth and young adult cases per hospital were observed over time (7.4 cases/center in 2015 vs. 6.7 cases/center in 2018). Overall, < 5% of cases required reoperation, reintervention, and readmission, or led to serious complications within 30 days of surgery. Multivariable logistic regression analysis identified RYGB as the single greatest independent predictor of serious complications (OR 3.1; 95% CI 2.58-3.64; p < 0.0001). Additional factors predictive of serious complications included female sex (OR 1.31; 95% CI 1.01-1.70; p = 0.04), sleep apnea (OR 1.27; 95% CI 1.02-1.58), and non-insulin-dependent diabetes (OR 1.35; 95% CI 1.04-1.75; p = 0.025). CONCLUSION Bariatric surgery in youth is safe but comprised only 3.7% of total MBSAQIP cases from 2015 to 2018. These data should serve as a call to government and healthcare agencies to develop policies and strategies that prioritize bariatric surgery for young people living with severe obesity.

Abstract
BACKGROUND Current bariatric surgery studies have focused on traditional outcomes such as mortality and morbidity and have thus far have neglected an important marker of surgical care- discharge destination. OBJECTIVES The aim of this study was to 1) characterize the prevalence of and clinical characteristics of patients who undergo bariatric surgery with respect to discharge disposition and to 2) evaluate factors which predict alternate care facility (ACF) discharge. SETTING Participating Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) centers. METHODS Data was extracted from the MBSAQIP data registry from 2015 to 2018. All primary Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) procedures were included while prior revisional surgeries and emergency surgeries were excluded. Our primary objective was to characterize the prevalence of and clinical characteristics of patients who undergo bariatric surgery and are discharged to an alternate care facility (ACF). Our secondary outcome was to identify predictors of discharge to an ACF using multivariable logistic regression modeling. RESULTS Most patients (n = 588,256; 99.6%) were discharged home while only a small proportion were discharged to an ACF (n = 1502; .4%). Patients discharged to an ACF were older (51.5 ± 13.5 yr versus 44.4 ± 12.0 yr; P < .0001), of increased body mass index (49.7 ± 11.9 kg/m2 versus 45.3 ± 7.8 kg/m2; P < .0001), and more likely to be of male sex (26.8% versus 20.4%; P < .0001). Patients with hypertension (65.2% versus 47.9%; P < .0001), dyslipidemia (40.1% versus 23.7%; P < .0001), sleep apnea (52.7% versus 38.1%; P < .0001), and medication-dependent diabetes (39.5% versus 26.3%; P < .0001) were more likely to be discharged to an ACF. Multivariable logistic regression revealed that partially dependent and dependent functional status were the single greatest preoperative predictors of ACF discharge with an 8- and 7-fold respective increase in odds of ACF versus patients of independent functional status. CONCLUSION Impaired functional status was the single greatest independent preoperative predictor of ACF discharge, providing evidence against the current use of a strict age cut-off criteria and support for implementation of a more patient-centered functional approach in selection of surgical candidates.
