Rate Of Bariatric Surgery Research Articles

A population based study of bariatric surgery in Illinois.

Utilization of metabolic and bariatric surgery has increased significantly over the last 2decades, yet barriers to access remain. This study aimed to 1) define rates of metabolic and bariatric surgery utilization for qualifying adults in Illinois and 2) describe patient characteristics associated with undergoing surgery at Illinois hospitals with low metabolic and bariatric surgery volume. Metabolic and bariatric surgery at all nonfederal Illinois hospitals was included. Illinois hospital administrative data for 2016-2022 metabolic and bariatric surgery procedures (numerators) and Illinois Behavioral Risk Factor Surveillance System population estimates (denominators) were used to compute metabolic and bariatric surgery rates per estimated 100,000 Illinois residents ages 18-69 who qualified for metabolic and bariatric surgery based on National Institutes of Health Guidelines. Zip code median income was obtained from census data. Multivariable logistic regression was used to identify patient characteristics associated with receiving metabolic and bariatric surgery at low volume hospitals (LVHs), defined as less than 50 annual bariatric procedures. The average annual metabolic and bariatric surgery rate was 702 per 100,000 qualifying Illinois adults. Rates were highest among non-Hispanic Black patients (890/100,000) and lowest for Hispanic patients (396/100,000) and patients from zip codes with median household income <$75,000. Lower median household income was the only characteristic associated with use of LVHs. Metabolic and bariatric surgery procedures almost doubled over the study period in Illinois, increasing the most for non-Hispanic Black and Medicaid patients. However, Hispanic and low-income patients still have rates well below the state average.

Major evidence of nutritional and metabolic management in the context of bariatric surgery: a systematic review

Introduction: Approximately $315 billion is spent annually on the medical cost of obesity in adult patients in the United States alone. According to the American Society for Metabolic and Bariatric Surgery (ASMBS), the rate of bariatric surgery (BS) increased from 158,000 in 2011 to 196,000 in 2015. This increase in invasive techniques does not eliminate unhealthy habits, therefore, lifestyle modifications, such as healthy eating and correct physical activity programs, can improve surgical results. Objective: To establish the main nutritional and metabolic management strategies in the context of bariatric surgery, to modulate and reduce the problems caused by nutrient deficit. Methods: The systematic review rules of the PRISMA Platform were followed. The search was conducted from May to June 2024 in the Web of Science, Scopus, PubMed, Science Direct, Scielo, and Google Scholar databases. The quality of the studies was based on the GRADE instrument and the risk of bias was analyzed according to the Cochrane instrument. Results and Conclusion: A total of 135 articles were found. 42 articles were fully evaluated and 18 were included and developed in the present systematic review study. Considering the Cochrane tool for risk of bias, the overall assessment resulted in 22 studies with a high risk of bias and 24 that did not meet GRADE and AMSTAR-2. Most studies presented homogeneity in their results, with X2=79.7%&gt;50%. It was concluded that the recommendations were gathered to assist in individualized clinical practice in the nutritional management of patients with obesity. In general, patients with obesity have significantly lower concentrations of serum iron, folic acid, vitamins A, B6, B12, C, 25-hydroxyvitamin D, and lipid-standardized vitamin E. Before bariatric surgery, nutritional status should be analyzed and preoperative weight loss can be attempted. Very low-calorie diets and very low-calorie ketogenic diets are prescribed in the last months before surgery. It was noted that the recommendations were gathered to assist in individualized clinical practice in the nutritional management of patients with obesity, including nutritional management. Iron status may be affected by adipose tissue inflammation and increased expression of the systemic iron regulatory protein hepcidin. The postoperative recommendation for vitamin B12 (cobalamin) should be 350-500 micrograms/1000 micrograms monthly, and for folate (folic acid) in the postoperative period should be 1000 micrograms per day.

Disparities in Access to Bariatric Surgery in North Carolina.

This study sought to identify factors that contribute to disparities in access to bariatric surgery in North Carolina (NC). Using the rate of bariatric surgery in the county with the best health outcome as the reference, we calculated the Surgical Equity Index (SEI) in the remaining counties in NC. Approximately 2.95 million individuals (29%) were obese in NC. There were 992 (.5%) bariatric procedures performed on a population of 194 209 individuals with obesity in the Reference County (RC). The mean SEI for bariatric surgery in NC was .47 (SD .17, range .15-.95). A statistically significant difference was observed in 89 counties. Univariable analyses identified the following variables to be significantly associated with the SEI: percent of population living in rural areas (% rural) (relative rate change in SEI [RR] = .994, 95% CI .92-.997; <.0001), median household income (RR = 1.0, 95% CI = 1.0-1.0; P = .0002), prevalence of diabetes (RR = .947, 95% CI .917-.977; .0006), the primary care physician ratio (RR = .995, 95% CI .991-.998; P = .006), and percent uninsured adults (RR = .955, 95% CI .927-.985; P = .003). By multivariable hierarchical regression analysis, only the % rural remained statistically associated with a low SEI (RR = .995 per 1% increase in % rural, 95% CI = .992, .998; P = .0002). The percent rural is the most significant predictor of disparities in access to bariatric surgery. For every 1% increase in % rural, the rate of surgery decreased by .5%. Understanding the characteristics of rurality that are barriers to access is crucial to mitigate disparities in bariatric surgical access in NC.

Ghrelin enhances tubular magnesium absorption in the kidney.

Osteoporosis after bariatric surgery is an increasing health concern as the rate of bariatric surgery has risen. In animal studies mimicking bariatric procedures, bone disease, together with decreased serum levels of Ca2+, Mg2+ and the gastric hormone Ghrelin were described. Ghrelin regulates metabolism by binding to and activating the growth hormone secretagogue receptor (GHSR) which is also expressed in the kidney. As calcium and magnesium are key components of bone, we tested the hypothesis that Ghrelin-deficiency contributes to osteoporosis via reduced upregulation of the renal calcium channel TRPV5 and the heteromeric magnesium channel TRPM6/7. We expressed GHSR with TRPV5 or TRPM6/7 channel in HEK293 cells and treated them with purified Ghrelin. Whole-cell current density was analyzed by patch-clamp recording. Nephron-specific gene expression was performed by tubular microdissection followed by qPCR in wild-type (WT) mice, and immunofluorescent imaging of GHSR-eGFP mice. Tubular magnesium homeostasis was analyzed in GHSR-null and WT mice at baseline and after caloric restriction. After Ghrelin exposure, whole-cell current density did not change for TRPV5 but increased for TRPM6/7 in a dose-dependent fashion. Applying the Ghrelin-mimetic (D-Trp7, Ala8,D-Phe10)-α-MSH (6-11) amide without and with the GHSR antagonist (D-Lys3)-GHRP6, we confirmed the stimulatory role of Ghrelin towards TRPM6/7. As GHSR initiates downstream signaling via protein kinase A (PKA), we found that the PKA inhibitor H89 abrogated TRPM6/7 stimulation by Ghrelin. Similarly, transfected Gαs, but not the Gαs mutant Q227L, nor Gαi2, Gαq, or Gα13 upregulated TRPM6/7 current density. In microdissected TALs and DCTs similar levels of GHSR mRNA were detected. In contrast, TRPM6 mRNA was expressed in the DCT and also detected in the TAL at 25% expression compared to DCT. Immunofluorescent studies using reporter GHSR-eGFP mice showed a strong eGFP signal in the TAL but surprisingly displayed no eGFP signal in the DCT. In 3-, 6-, and 9-month-old GHSR-null and WT mice, baseline serum magnesium was not significantly different, but 24-h urinary magnesium excretion was elevated in 9-month-old GHSR-null mice. In calorically restricted GHSR-null mice, we detected excess urinary magnesium excretion and reduced serum magnesium levels compared to WT mice. The kidneys from calorically restricted WT mice showed upregulated gene expression of magnesiotropic genes Hnf1b, Cldn-16, Cldn-19, Fxyd-2b, and Parvalbumin compared to GHSR-null mice. Our in vitro studies show that Ghrelin stimulates TRPM6/7 via GHSR and Gαs-PKA signaling. The murine studies are consistent with Ghrelin-GHSR signaling inducing reduced urinary magnesium excretion, particularly in calorically restricted mice when Ghrelin levels are elevated. This effect may be mediated by Ghrelin-upregulation of TRPM6 in the TAL and/or upregulation of other magnesiotropic genes. We postulate that rising Ghrelin levels with hunger contribute to increased renal Mg2+ reabsorption to compensate for lack of enteral Mg2+ uptake.

Prevalence of obesity and bariatric surgery among medical students in Riyadh, Saudi Arabia.

Bariatric surgery is considered as a successful weight loss intervention in patients with high body mass index (BMI) and also in patients who are unable to lose weight in a nonsurgical way. To measure the prevalence of obesity among medical students and the association between obesity and lifestyle and obesity and the rate of bariatric surgery in obese students. This is a cross sectional study which included 301 medical students in Riyadh. An online pretested and validated questionnaire was distributed among medical students. The collected data included weight, height, family background, lifestyle, and past medical and surgical history. Our results demonstrated that the prevalence of overweight, obesity, and morbid obesity was 26.6%, 9.6%, and 6.3%, respectively, among medical students. Only 44.9% of them had a family history of obesity (n = 135). Upon assessment of lifestyle, we found that 58.8% of them had a good lifestyle and 41.2% had a bad lifestyle. We found that 42.5% of medical students included in this study have obesity, and 44% of students had history of obesity in their family. In the obese group, 47.6% had a bad lifestyle. There was significant relationship between obesity and lifestyle among medical students (P = 0.0004). We found that 83.1% of students never thought of undergoing bariatric surgery, 10% of them had thought of undergoing it, and 7% of the students had undergone bariatric surgery. the prevalence of obesity is less among medical student in comparison to other subgroups. The educational level and environmental factors play an important role in the prevalence of obesity.

Metabolic and Bariatric Surgery Utilization Trends in the United States: Evidence From 2012 to 2021 National Electronic Medical Records Network.

Bariatric surgery has evolved over the past 2 decades yet assessing trends of bariatric surgery utilization in the growing eligible population is lacking. This study aimed to update the trends in bariatric surgery utilization, changes in types of procedures performed, and the characteristics of patients who underwent bariatric surgery in the United States, using real-world data. This retrospective descriptive observational study was conducted using the TriNetX, a federated electronic medical records network from 2012 to 2021, for adult patients 18 years old or older who had bariatric surgery. Descriptive statistical analysis was conducted to assess patients' demographics and characteristics. Annual secular trend analyses were conducted for the annual rate of bariatric surgery, and the specific procedural types and proportions of laparoscopic surgeries. A steady increase in the number of procedures performed in the United States over the first 6 years of the study, a plateau for the following 2 years, and then a decline in 2020 and 2021 (during the coronavirus disease 2019 pandemic). The annual rate of bariatric surgery was lowest in 2012 at 59.2 and highest in 2018 at 79.6 surgeries per 100,000 adults. During the study period, 96.2% to 98.8% of procedures performed annually were conducted laparoscopically as opposed to the open technique. Beginning in 2012, the Roux-en-Y gastric bypass (RYGB) procedure fell to represent only 17.1% of cases in 2018, along with a sharp decline in the adjustable gastric band (AGB) procedure, replaced by a sharp increase in the sleeve gastrectomy (SG) procedure to represent over 74% of cases in 2018. Bariatric surgery utilization in the United States showed a moderate decline in the number of RYGB procedures, which was offset by a substantial increase in the number of SG procedures and a precipitous drop in the annual number of AGB procedures.

National usage of bariatric surgery for class I obesity: an analysis of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program.

National and international consensus statements, as well as the National Institutes of Health (NIH), support the use of bariatric surgery for the treatment of class I obesity. Despite this, most payors within the United States limit reimbursement to the outdated 1991 NIH guidelines or a similar adaptation. This study aimed to determine the safety of bariatric surgery in patients with lower BMI compared with standard patients, as well as determine U.S. utilization of bariatric surgery in class I obesity in 2015-2019. A retrospective analysis was performed of the 2015-2019 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. Laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass patients were divided into body mass index cohorts: class I obesity (<35 kg/m2) and severe obesity (≥35 kg/m2). Differences in preoperative patient selection and postoperative outcomes were established, and frequency trends were delineated. Analysis included 760,192 surgeries with 8129 (1%) for patients with class I obesity. The patients with class I obesity were older, more commonly female, and with lower American Society of Anesthesiologists (ASA) class, but with higher rates of type 2 diabetes, hyperlipidemia, and gastroesophageal reflux disease (P < .05). Variation was found for operative time, length of stay, 30-day readmission, and composite morbidity. Minimal annual variation was found for bariatric surgeries performed for patients with class I obesity. The short-term safety of bariatric surgery in patients with class I obesity was corroborated by this study. Despite consensus statements and robust support, rates of bariatric surgery in patients with class I obesity have failed to increase and remain limited to 1%. This demonstrates the impact of the outdated 1991 NIH guidelines regarding access to care for these potentially life-saving surgeries.

Nutritional Neuropathies.

This article reviews the etiologies, presentations, and management of neuropathies related to nutritional deficiencies. Peripheral neuropathy can be the predominant or only manifestation of certain nutrient deficiencies. Cognitive difficulties or involvement of other parts of the central nervous system, such as the optic nerve and spinal cord, may accompany nutritional peripheral neuropathies. In most patients, the nutritional deficiency may have a single predominant cause, but in some cases, multiple causes may coexist. Obesity, for unclear reasons, can be associated with nutrient deficiencies. The rising rates of bariatric surgery and the incidence of nutrient deficiencies following bariatric surgery make this a particularly relevant topic for neurologists. Neuropathies caused by nutrient deficiencies are preventable with appropriate supplementation in high-risk situations. Early recognition and prompt treatment are essential to ensure an optimal outcome and minimize neurologic morbidity.

S1646 The Rate of Bariatric Surgery and Its Inpatient Complications in Morbidly Obese Patients With Inflammatory Bowel Disease

S1646 The Rate of Bariatric Surgery and Its Inpatient Complications in Morbidly Obese Patients With Inflammatory Bowel Disease

Laparoscopic sleeve gastrectomy to Roux-en-Y gastric bypass conversion versus primary Roux-en-Y gastric bypass: a propensity score matching analysis.

Secondary bariatric surgery rates have increased, accounting for approximately 19% of the total bariatric cases in the last years, most commonly conversion of sleeve gastrectomy to gastric bypass. Using the MBSAQIP, we evaluate the outcomes of this procedure compared to the primary RYGB surgery. The new variable, conversion of sleeve gastrectomy to RYGB in the 2020 and 2021 MBSAQIP database was analyzed. Patients who underwent primary laparoscopic RYGB and those who underwent laparoscopic sleeve gastrectomy to RYGB conversion were identified. Using Propensity Score Matching analysis, the cohorts were matched for 21 preoperative characteristics. We then compared 30-day outcomes and bariatric-specific complications between primary RYGB and conversion from sleeve gastrectomy to RYGB. There were 43,253 primary RYGB procedures performed and 6,833 conversions from sleeve gastrectomy to RYGB. The matched cohorts (n = 5912) for the two groups have similar pre-operative characteristics. Propensity-matched outcomes showed that conversion from sleeve gastrectomy to RYGB was associated with more readmissions (6.9% vs 5.0%, p < 0.001), interventions (2.6% vs 1.7%, p < 0.001), conversion to open (0.7% vs 0.2%, p < 0.001), length of stay (1.79 ± 1.77days vs 1.62 ± 1.66days, p < 0.001), and operative time (119.16 ± 56.82min vs 138.27 ± 66.00, p < 0.001). There were no significant differences in mortality (0.1% vs 0.1%, p = 0.405), and bariatric-specific complications such as anastomotic leak (0.5% vs 0.4%, p = 0.585), intestinal obstruction (0.1% vs 0.2%, p = 0.808), internal hernia (0.2% vs 0.1%, p = 0.285) or anastomotic ulcer (0.3% vs 0.3%, p = 0.731) rates. Conversion from sleeve gastrectomy to RYGB is a safe and feasible operation with reasonable outcomes compared with primary RYGB.

Autologous Breast Reconstruction after Massive Weight Loss: Understanding Risks in a Growing Population.

Massive weight loss (MWL) may have suboptimal effects on tissues used for autologous reconstruction. With the rising rates of obesity and bariatric surgery, more patients who have experienced MWL will be presenting for breast reconstruction. The authors hypothesize that autologous breast reconstruction in patients with a history of MWL will have more complications and require more revisions compared with reconstruction in patients without a history of MWL. A retrospective review was performed on patients who underwent autologous breast reconstruction by five microsurgeons at an academic institution from 2009 through 2020. Patients with a history of bariatric surgery or greater than 50-pound weight loss were identified and compared with patients who had not experienced MWL. Analysis compared demographics, operative details, complications, revision rates, and BREAST-Q scores. Of 916 patients who underwent 1465 flaps, 39 patients with MWL (4.3%) underwent 68 flaps (4.6%), and 877 patients without MWL underwent 1397 flaps. MWL patients were more likely to require blood transfusions postoperatively ( P = 0.005); experienced more surgical-site infections ( P = 0.02), wound-healing complications of flap ( P = 0.007) and donor sites ( P = 0.03), and late partial flap losses ( P = 0.03); and required more revisional surgery for flap ( P = 0.009) and donor sites ( P = 0.01). BREAST-Q scores were not statistically different for satisfaction with breasts or surgeon but were lower in MWL patients for psychosocial ( P = 0.01) and sexual well-being ( P = 0.04). Reconstructive surgeons should expect increased postoperative complications when performing autologous breast reconstruction in patients who have experienced MWL. These patients should be counseled on the possibility of an increased risk of postoperative complications and need for revisional surgery. Risk, II.

Factors Associated With Loss to Follow-up After Laparoscopic Sleeve Gastrectomy: A Single-Center Retrospective Study.

After bariatric surgery, postoperative follow-up is important for evaluating long-term outcomes, such as successful weight loss and improvement of metabolic parameters. However, many patients are lost to follow-up within 1 year. This study aimed to identify the follow-up rate of bariatric surgery and predictive factors of loss to follow-up (LTF). We retrospectively reviewed the data of 61 patients receiving bariatric surgery for obesity (laparoscopic sleeve gastrectomy; LSG group) and 872 for early gastric cancer (EGC group) from November 2018 to July 2020 in a single center. After 1:1 matching, we compared the LTF rate. In the LSG group, we analyzed the factors associated with LTF. Additionally, we collected weight data in the LTF group by a telephone survey. By 1:1 matching, 47 patients for each group were identified. The LTF rates of the LSG and EGC groups were 34.0% (16 patients) and 2.1% (one patient), respectively (P=0.0003). In the LSG group, the LTF rate increased over the postoperative month. Of the patients, 29.5% who missed a scheduled appointment within one year comprised the LTF group. In the analysis, no significant factors associated with LTF were identified. The only factor with borderline significance was dyslipidemia with medication (P=0.094). The LSG group demonstrated a high LTF rate, although adherence to follow-up was closely related to postoperative outcomes. Therefore, educating patients on the significance of follow-up is important. Particularly, continuous efforts to identify the associated factors and develop a multidisciplinary management protocol after bariatric surgery are necessary.

Blood Group and Response to Bariatric Surgery in Morbidly Obese Patients: A Retrospective Study in Saudi Arabia.

To explore the relationship between the blood group of patients and their response to bariatric surgery and to identify predictors of better outcomes. This was a retrospective cross-sectional analysis of patients who underwent laparoscopic sleeve gastrectomy for morbid obesity between 2014 and 2020 at King Saud University Medical City in Riyadh, Saudi Arabia. This study included 1434 individuals. The mean change in BMI (pre- versus post-BMI) differed statistically significantly between blood groups (p ≤ 0.01). The greatest drop in body weight was seen in individuals with the AB-negative blood type (56.0 (21.4) kg), which corresponds to the greatest percentage of reduction from baseline (47.7% (14.8)). The mean BMI of the patients decreased by 34.7% (9.2) from a mean pre-operation BMI of 45.5 (8.4) kg/m2 to 29.7 (6.1) kg/m2 (p ≤ 0.001). After laparoscopic sleeve gastrectomy, male patients and those with the B-negative blood type are more likely to see a greater BMI reduction (pre-operation compared to post-operation) (p ≤ 0.05). For morbidly obese patients, laparoscopic sleeve gastrectomy demonstrated promising weight loss outcomes. Blood groups may be able to predict the success rate of bariatric surgery in morbidly obese patients.

Factors associated with bariatric surgery rates in federative units in Brazil.

To analyze the socioeconomic, demographic and health management factors associated with bariatric surgery rates performed by the Brazilian Unified Health System (SUS) in the federative units in Brazil. Description and analysis of bariatric surgeries rates (per 100,000 inhabitants) performed by SUS in adults from 18 to 65 years old, in the 27 federative units of Brazil, between 2008 and 2018; thus, the econometric methodology of count panel with negative binomial distribution (population-averaged, fixed effects and random effects) was used. Socioeconomic and demographic factors were also investigated, considering the real gross domestic product per capita, the average years of study of adults and life expectancy at birth, and those of health management, given the primary health care coverage, the rate of digestive system surgeons and the rate of hospitals accredited in high complexity care to patients with obesity in the SUS. In regional terms, the performance of public bariatric surgeries in Brazil over the period analyzed suffered a great disparity; the procedures happen mostly in the South and Southeast regions, and scarcely in the North region. Moreover, we found a positive relationship between the rate of bariatric surgeries and life expectancy, the rate of digestive system surgeons and the rate of hospitals accredited in high complexity care; however, the average number of years of adult study and coverage of primary health care is a negative association regarding real gross domestic product per capita. In the period analyzed, the investigated factors explained the rate of bariatric surgeries. Therefore, to train specialized health professionals, the accreditation of hospitals according to the legal framework, preventive actions of primary care, and socioeconomic and demographic factors, conditioning for the offer of surgical treatment by the SUS were crucial. Thus, these are all relevant factors for the formulation of public policies in this area.

African American Patients Experience Worse Outcomes than Hispanic Patients Following Bariatric Surgery: an Analysis Using the MBSAQIP Data Registry.

Obesity rates in Hispanics and African Americans (AAs) are higher than in Caucasians in the USA, yet the rate of metabolic and bariatric surgery (MBS) for weight loss remains lower for both Hispanics and AAs. Patient demographics and outcomes of adult AA and Hispanic patients undergoing sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) procedures were analyzed using the MBSAQIP dataset [2015-2018] using unmatched and propensity-matched data. In total, 173,157 patients were included, of whom 98,185 were AA [56.7%] [21,163-RYGB; 77,022-SG] and 74,972 were Hispanic [43.3%] [20,282-RYGB; 54,690-SG]). Preoperatively, the AA cohort was older, had more females, and higher BMIs with higher rates of all tracked obesity-related medical conditions except for diabetes, venous stasis, and prior foregut surgery. Intra- and postoperatively, AAs were more likely to experience major complications including unplanned ICU admission, 30-day readmission/reintervention, and mortality. After propensity matching, the differences in ED visits, treatment for dehydration, 30-day readmission, 30-day intervention, and pulmonary embolism remained for both SG and RYGB cohorts. Progressive renal insufficiency and ventilator use lost statistical significance in both cohorts. Conversely, 30-day reoperation, postoperative ventilator requirement, unplanned intubation, unplanned ICU admission, and mortality lost significance in the RYGB cohort, but not SG patients. Outcomes for AA patients were worse than for Hispanic patients, even after propensity matching. After matching, differences in major complications and mortality lost significance for RYGB, but not SG. These data suggest that outcomes for RYGB may be driven by the presence and severity of pre-existing patient-related factors.

The effects of using telemedicine for introductory bariatric surgery seminars during the COVID-19 pandemic.

BackgroundThe COVID-19 pandemic required immediate systematic change in healthcare delivery. Many institutions relied on telemedicine as an alternative to in-person visits. There is limited data in the bariatric surgery literature to determine how telemedicine impacts patient volume. This study evaluates the effects of using telemedicine for introductory bariatric surgery seminars on patient volume at a single institution.MethodsA retrospective review was performed before and after implementing virtual introductory seminars for bariatric surgery patients at a comprehensive metabolic and surgery center. The effect on attendance rates for introductory seminars and completion rates of bariatric surgery was evaluated. ResultsThe introductory seminar attendance rate for the in-person/pre-telemedicine period, April 2019 to February 2020, was compared to that of the virtual/post-telemedicine period, June 2020 to April 2021. A total of 836 patients registered for an introductory seminar during the pre-telemedicine period with a 65.79% attendance rate. In the post-telemedicine period, 806 patients registered with a 67.87% attendance rate, which was not statistically different (p = 0.37, 95% CI − 0.03–0.07). Completion rates of bariatric surgery were analyzed using June 2019 to October 2019 as the pre-telemedicine period and June 2020 to October 2020 as the post-telemedicine period. Similarly, there was no difference between the pre-telemedicine surgery rate of 23.43% and post-telemedicine surgery rate of 19.68% (p = 0.31, 95% CI − 0.11–0.04).ConclusionDespite abruptly transitioning to virtual introductory bariatric seminars, there was no change in attendance rates nor was there a difference in the number of patients progressing through the program and undergoing bariatric surgery at our institution. This demonstrates similar efficacy of telemedicine and in-person introductory seminars for bariatric surgery patients, which supports telemedicine as a promising tool for this patient population in the post-pandemic era.Graphical abstract

Challenges in Bariatric Surgery: Outcomes in Patients Having Three or More Bariatric Procedures.

Over the last two decades, a progressive increase in failure rate of bariatric surgery (BS) has occurred in conjunction with an exponential increase in BS worldwide. Bariatric surgeons are confronted with challenging situations in patients with a complex bariatric history. In this study, we aim to evaluate the feasibility and outcomes of revisional BS in patients with at least two or more previous bariatric procedures. Data were retrospectively retrieved from a prospectively held database of bariatric procedures performed at our tertiary referral bariatric center and included procedures done from February 2013 up to April 2019 by a single center. Thirty patients underwent a third bariatric procedure. The median age was 40 (18-57) and 54 (27-69) years at the time of the first and the last procedures, respectively. Laparoscopic adjustable gastric banding was the first procedure in 26 patients. The complication rate was 33%; no patient required additional surgery because of postoperative complications. A total weight loss of 29.6% and an excess loss of 53.4% were obtained at a mean follow-up of 61months after the last redo bariatric procedure. This study indicates that redo BS either conversional or revisional is feasible and effective in patients with a complex bariatric history including two or more previous procedures. Careful patients' selection is mandatory and extensive information should be given on the increased risk of postoperative complications.

Obesity treatment initiation, retention, and outcomes in the Veterans Affairs MOVE! Program among rural and urban veterans.

Rural veterans have high obesity rates. Yet, little is known about this population's engagement with the Veterans Affairs (VA) weight management program (MOVE!). The study objective is to determine whether MOVE! enrollment, anti-obesity medication use, bariatric surgery use, retention, and outcomes differ by rurality for veterans with severe obesity. This is a retrospective cohort study using Veterans Health Administration patient databases, including VA patients with severe obesity during 2015-2017. Patients were categorized using Rural-Urban Commuting Area codes. Primary outcomes included proportion of patients and risk-adjusted likelihood of initiating VA MOVE!, anti-obesity medication, or bariatric surgery and risk-adjusted highly rural|Hazard Ratio (HR) of any obesity treatment. Secondary outcomes included treatment retention (≥12weeks) and successful weight loss (5%) among patients initiating MOVE!, and risk-adjusted odds of retention and successful weight loss. Among 640,555 eligible veterans, risk-adjusted relative likelihood of MOVE! treatment was significantly lower for rural and HR veterans (HR=0.83, HR=0.67, respectively). Initiation rates of anti-obesity medication use were significantly lower as well, whereas bariatric surgery rates, retention, and successful weight loss did not differ. Overall treatment rates with MOVE!, bariatric surgery, and anti-obesity medications remain low. Rural veterans are less likely to enroll in MOVE! and less likely to receive anti-obesity medications than urban veterans.

Necessity of Patients' Satisfaction after Bariatric and Metabolic Surgery; Assessing According the BAROS Score

Surgery-related outcomes of bariatric procedures do not depend on only weight loss, but also resolution of comorbidities and improvement of quality of life (QOL) are of great importance. Severe obesity is associated with decreased quality of life. Therefore, bariatric surgery improves the quality of life. In this regard, there are many tools to assess the quality of life, one of which is the Bariatric Analysis and Reporting Outcome System Score (BAROS) containing of self-esteem, physical activity, social activity, work sexual activity, and food items. Most surgeons consider the success rate of bariatric surgery in respect of weight loss and improvement of comorbidities. However, an important factor that should not be forgotten is patients' satisfaction and QOL, which can be assessed with BAROS score. The BAROS score divided into five groups (-3 to -2.1: very poor, -2 t0 -1.1: poor, -1 to 1: fair, 1.1 to 2: good, and 2.1 to 3: very good). Assessing the patient's satisfaction and QOL following bariatric and metabolic surgeries is strongly recommended.

Examination of Elective Bariatric Surgery Rates Before and After US Affordable Care Act Medicaid Expansion

There is limited evidence on whether the Affordable Care Act Medicaid expansion beginning in 2014 improved access to elective procedures. Uninsured individuals are at higher risk of obesity and may have experienced improved uptake of bariatric surgery following Medicaid expansion. To examine the association between Medicaid expansion and the receipt of inpatient elective bariatric surgery among Medicaid-covered and uninsured individuals aged 26 to 64 years. This cohort study used difference-in-differences analysis of all-payer data (2010-2017) of 637 557 elective bariatric surgeries for patients aged 26 to 74 years from 11 Medicaid expansion states and 6 nonexpansion states. Nonexpansion states and individuals aged 65 to 74 years were control cohorts. Data analysis was performed from July 6, 2020, to July 23, 2021. Living in a Medicaid expansion state. The main outcomes were the (1) number of elective bariatric surgeries, (2) population count, and (3) rate of bariatric surgery (number of surgeries per 10 000 population) among Medicaid-covered and uninsured individuals. Of the 600 798 elective bariatric surgeries in adults aged 26 to 64 years between 2010 and 2017 from the 17 study states, Medicaid-covered and uninsured individuals accounted for 18.3% of the total surgery volume in expansion states and 14.5% in nonexpansion states. A total of 296 798 patients (78.9%) in expansion states were women vs 177 386 (78.9%) in nonexpansion states. Among individuals aged 26 to 64 years, the median age was 44 (IQR, 37-52) years. Racial and ethnic distribution was non-Hispanic White, 60.2%; non-Hispanic Black, 17.7%; Hispanic, 16.6%; and other, 5.5%. Between 2013 and 2017, the volume of bariatric surgeries for Medicaid-covered and uninsured patients increased annually by 30.3% in expansion states and 16.5% in nonexpansion states. Medicaid expansion was associated with a 36.6% annual increase (95% CI, 8.2% to 72.5%) in surgery volume, a 9.0% annual increase (95% CI, 3.8% to 14.5%) in the population, and a 25.5% change (95% CI, -1.3% to 59.4%) in the rate of bariatric surgery. By race and ethnicity, Medicaid expansion was associated with an increase in the rate of bariatric surgery among non-Hispanic White individuals (31.6%; 95% CI, 6.1% to 63.0%) but no significant change among non-Hispanic Black (5.9%; 95% CI, -19.8% to 39.9%) and Hispanic (28.9%; 95% CI, -24.4% to 119.8%) individuals. This cohort study found that Medicaid expansion was associated with increased rates of bariatric surgery among lower-income non-Hispanic White individuals, but not among Hispanic and non-Hispanic Black individuals.
