Abstract
The laparoscopic sleeve gastrectomy is the most common bariatric surgery performed to promote weight loss and improve obesity-related comorbidities. As the number of patients undergoing sleeve gastrectomy increases, so does the prevalence of complications. It is crucial to recognize both common and unusual complications of sleeve gastrectomy to properly diagnose and manage them. We present a unique case of gastric outlet obstruction not visualized on initial imaging and acute pancreatitis following a sleeve gastrectomy. We recommend performing an endoscopy and ordering serum lipase levels in a patient with negative CT scans but persistent postoperative nausea, vomiting, and abdominal pain. The management of postoperative gastric outlet obstruction includes supportive care, balloon dilation of the stenotic area, or gastric bypass if symptoms persist.

When the COVID-19 pandemic collides with the obesity epidemic in the United States: a national survey. Surg Obes Relat Dis 2023; 19:434-439. [PMID: 37019774 PMCID: PMC9995298 DOI: 10.1016/j.soard.2023.02.020] [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: 02/08/2023] [Accepted: 02/27/2023] [Indexed: 03/30/2023]
Abstract
Background COVID-19 has disrupted life and put a spotlight on obesity as a risk factor for severe COVID-19 outcomes. Five years ago, we performed a survey exploring ways Americans view obesity and its treatment. We repeated the survey in the COVID-19 era to explore the impact of this once-in-a-century public health crisis on public perception and behavior surrounding obesity. Objective To explore if America’s views on obesity have changed after more than 2 years of living through COVID-19. Setting The national survey was conducted by XXXXXX from December 10 to 28, 2021. Methods We revisited some of the questions posed in a survey 5 years ago and added questions asking whether COVID-19 has changed views on obesity. We surveyed 1714 Americans sampled from a probability-based, nationally representative panel. Responses of Americans to questions about obesity were compared with the same or similar questions asked 5 years ago. Results COVID-19 has led to a change in how Americans view risks of obesity and benefits of treatment. Nearly one third (29%) of Americans became more worried about having obesity, and this is more pervasive among Black and Hispanic Americans (45%). This heightened concern led an estimated 28 million people to explore treatments not considered before the pandemic, including 6.4 million who thought about bariatric surgery or taking prescription obesity drugs. Conclusions COVID-19 may have heightened Americans’ worry about obesity. This may present an opportunity for conversations about treatments, including metabolic surgery.

Bone 2023; 167:116608. [PMID: 36368466 PMCID: PMC10064867 DOI: 10.1016/j.bone.2022.116608] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 10/27/2022] [Accepted: 11/05/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Peptide YY (PYY) is an anorexigenic gut hormone that also has anti-osteogenic effects, inhibiting osteoblastic activity and inducing catabolic effects. It has been postulated that increases in PYY after Roux-en-Y gastric bypass (RYGB) contribute to declines in bone mineral density (BMD) and increases in bone turnover. The aim of this study is to determine the role of the PYY Y2-receptor in mediating bone loss post-RYGB in mice. METHODS We compared adult male wildtype (WT) and PYY Y2 receptor-deficient (KO) C57BL/6 mice that received RYGB (WT: n = 8; KO: n = 9), with sham-operated mice (Sham; WT: n = 9; KO: n = 10) and mice that were food-restricted to match the weights of the RYGB-treated group (Weight-Matched, WM; WT: n = 7; KO: n = 5). RYGB or sham surgery was performed at 15-16 weeks of age, and mice sacrificed 21 weeks later. We characterized bone microarchitecture with micro-computed tomography (μCT) at the distal femur (trabecular) and femoral midshaft (cortical). Differences in body weight, bone microarchitecture and biochemical bone markers (parathyroid hormone, PTH; C-telopeptide, CTX; and type 1 procollagen, P1NP) were compared using 2-factor ANOVA with Tukey's adjustments for multiple comparisons. RESULTS Body weights were similar in the WT-RYGB, WT-WM, KO-RYGB, and KO-WM: 41-44 g; these groups weighed significantly less than the Sham surgery groups: 55-57 g. Trabecular BMD was 31-43 % lower in RYGB mice than either Sham or WM in WT and KO groups. This deficiency in trabecular bone was accompanied by a lower trabecular number (19 %-23 %), thickness (22 %-30 %) and increased trabecular spacing (25 %-34 %) in WT and KO groups (p < 0.001 for all comparisons vs. RYGB). RYGB led to lower cortical thickness, cortical tissue mineral density, and cortical bone area fraction as compared to Sham and WM in WT and KO groups (p ≤ 0.004 for all). There were no interactions between genotype and bone microarchitecture, with patterns of response to RYGB similar in both WT and KO groups. CTX and P1NP were significantly higher in RYGB mice than WM in WT and KO groups. PTH did not differ among groups. CONCLUSIONS RYGB induced greater trabecular and cortical deficits and high bone turnover than observed in weight-matched mice, with a similar pattern in the WT and Y2RKO mice. Thus, skeletal effects of RYGB are independent of weight loss, and furthermore, PYY signaling through Y2R is not a key mediator of bone loss post-RYGB.

Abstract
BACKGROUND Bariatric surgery has shown an improvement in obesity and obesity-related disease in many clinical trials and single center studies. However, real-world data, including data from non-centers of excellence, is sparse. OBJECTIVES To provide clinical outcomes of patients who underwent bariatric surgery in real-world clinical setting. SETTING Academic Institution. METHODS Adults with obesity undergoing Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy (SG), and a control group (CG) between 2007 and 2019 were identified. The CG represented patients with a previous visit to a bariatric surgeon without a subsequent surgery. Cohorts were matched on age, gender, ethnicity, baseline body mass index (BMI), and presence of diabetes and hypertension. Groups were compared in terms of co-morbidities, weight loss, and chronic conditions for three years. RESULTS A total of 61 313 patients were identified. From these, 14 916 RYGB and 20 867 SG patients were matched to the CG (n = 16 562). The median BMI loss three years after surgery was 28.7% (interquartile range [IQR] 20.8%-36.2%) and 20.5% (IQR 13.5%-28.6%) for RYGB and SG groups, respectively. The CG had a median BMI loss of 6.7% with IQR of 20.4% decrease to 1.78% gain. At three years postoperatively, HbA1C decreased by 13% for RYGB and 5.9% for the SG group. The probabilities of remission from diabetes, hypertension, and low high-density lipoprotein cholesterol were significantly higher among patients who had surgery compared to the CG. For both RYGB and SG, the estimated probabilities of remission were similar. CONCLUSION This study shows that bariatric surgery performed in the real-world clinical setting is an effective therapy for various expressions of the metabolic syndrome with results that are comparable to randomized control trials.

Operative management of recalcitrant marginal ulcers following laparoscopic Roux-en-Y gastric bypass for morbid obesity: a systematic review. Surg Obes Relat Dis 2021; 17:2082-2090. [PMID: 34433513 DOI: 10.1016/j.soard.2021.07.017] [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: 03/25/2021] [Revised: 05/18/2021] [Accepted: 07/17/2021] [Indexed: 10/20/2022]
Abstract
One of the short- and long-term complications following Roux-en-Y gastric bypass (RYGB) for morbid obesity is the development of marginal ulcers (MUs). Although chronic and recalcitrant/recurrent marginal ulcers (rMUs) are common, there is no consensus on their optimal management. The objective of this study was to perform a systematic review of the elective operative management of rMUs. A systematic search of the literature was conducted. Relevant databases were searched up to May 16, 2020. Articles were included if they met the following inclusion criteria: (1) bariatric patients were included as the study population, (2) laparoscopic RYGB was performed as the index operation, (3) study patients developed rMUs, and (4) MUs required elective operative (surgical, endoscopic) interventions. Quality of articles was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system. The search identified 3470 citations; of these, 16 observational studies were included. Elective management of rMUs consisted of endoscopic (oversewing ± stents) and surgical interventions (gastrojejunostomy revision, vagotomy, conversion to sleeve gastrectomy, subtotal/total gastrectomy, reversal to normal anatomy). Quality of the studies as assessed by the GRADE system was low to very low. Recalcitrant/recurrent MUs are challenging complications both for bariatric patients and for their treating surgeons. There are no established algorithms for the management of rMUs, and the currently available evidence in the literature is limited both in quantity and in quality. Future multicentre, multisurgeon, randomized, controlled trials are needed to address this issue.

Abstract
PURPOSE The aim of this study is to evaluate the change in rate of increase of bariatric surgery performed compared to the growth of obesity and severe obesity in the United States (US). MATERIALS AND METHODS The number of primary adult bariatric procedures performed in the US between 2015 and 2018 was obtained from the Metabolic and Bariatric Surgery Accreditation Quality and Improvement Project (MBSAQIP) database. The US Census database was used to derive age-adjusted obesity and severe obesity prevalence among adults. Prevalence of bariatric surgery, by year, was estimated as the ratio of the number of patients undergoing surgery and the projected number of eligible individuals for that year. RESULTS There were 627,386 bariatric procedures performed for body mass index (BMI) ≥ 30 kg/m2, of which 73.3% (n = 459,800) were performed for BMI ≥ 40 kg/m2. Although the rate of obesity increased by 3.32% per year during this period (RR = 1.0332 per year increase; 95% CI = 1.0313, 1.0352), the rate of surgery per eligible population increased by only 2.47% (RR = 1.0247 per year increase; 95% CI = 1.0065, 1.0432). The prevalence of severe obesity increased from 7.70% (n = 17,494,910) in 2015 to 9.95% (n = 23,135,039) in 2018 while the prevalence of surgery decreased from 0.588 per 100 eligible population in 2015 to 0.566 per 100 eligible population in 2018. CONCLUSION The rate of utilization has not kept up with the rate of increase in this disease, our costliest illness. There is a strong need to educate the public, healthcare professionals, insurance carriers, and legislators.

Obes Surg 2021; 30:1660-1670.

Abstract
BACKGROUND Recently, randomized controlled trials (RCTs) have indicated that bariatric surgery in nonseverely obese patients with a body mass index (BMI) less than 35 kg/m2 might be even superior to medical therapy with regard to type 2 diabetes mellitus (T2DM) remission, but the efficacy of laparoscopic Roux-en-Y gastric bypass (LRYGB) compared with laparoscopic sleeve gastrectomy (LSG) in nonseverely obese patients has not been conclusively determined. The objective of this study is to compare LRYGB versus LSG for T2DM in nonseverely obese patients. METHODS A meta-analysis identifying RCTs evaluating LRYGB versus LSG for T2DM in nonseverely obese patients was conducted. The primary outcome was T2DM remission. Additional analyses comprised percent excess weight loss (%EWL), BMI, waist circumference, hemoglobin A1c (HbA1c), fasting plasma glucose (FPG), serum lipid level, medication use, quality of life, and adverse events. RESULTS Four RCTs concerning total 296 patients were included. T2DM remission rate and %EWL were of no difference between the two bariatric procedures. LRYGB was associated with lower BMI, waist circumference, low-density lipoprotein, and higher high-density lipoprotein than LSG. However, HbA1c, FPG, total cholesterol, and triglyceride were not significantly different between the two surgical groups. The medication use and quality of life were improved in both two groups. The gastroesophageal reflux diseases of LRYGB group were less than that of LSG group. Dumping syndromes were noted more frequently in the LRYGB group. CONCLUSIONS Both LRYGB and LSG have comparative effect on resolving T2DM in nonseverely obese patients at midterm follow-up. Further RCTs should address the potential risks and long-term effects of LRYGB and LSG in nonseverely obese patients.

Abstract
BACKGROUND Bariatric surgery remains underutilized at a national scale, and insurance company reimbursement is an important determinant of access to these procedures. We examined the current state of coverage criteria for bariatric surgery set by private insurance companies. METHODS We surveyed medical policies of the 64 highest market share health insurance providers in the USA. ASMBS guidelines and the CMS criteria for pre-bariatric evaluation were used to collect private insurer coverage criteria, which included procedures covered, age, BMI, co-morbidities, medical weight management program (MWM), psychosocial evaluation, and a center of excellence designation. We derive a comprehensive checklist for pre-bariatric patient evaluation. RESULTS Sixty-one companies (95%) had defined pre-authorization policies. All policies covered the RYGB, and 57 (93%) covered the LAGB or the SG. Procedures had coverage limited to center of excellence in 43% of policies (n = 26). A total of 92% required a BMI of 40 or above or of 35 or above with a co-morbidity; however, 43% (n = 23) of policies covering adolescents (n = 36) had a higher BMI requirement of 40 or above with a co-morbidity. Additional evaluation was required in the majority of policies (MWM 87%, psychosocial evaluation 75%). Revision procedures were covered in 79% (n = 48) of policies. Reimbursement of a second bariatric procedure for failure of weight loss was less frequently found (n = 41, 67%). CONCLUSIONS A majority of private insurers still require a supervised medical weight management program prior to approval, and most will not cover adolescent bariatric surgery unless certain criteria, which are not supported by current evidence, are met.

Abstract
BACKGROUND Millions of Americans qualify for metabolic and bariatric surgery (MBS) based on the proportion of the population with severe obesity. Simultaneously, the use of electronic nicotine/non-nicotine delivery systems (ENDS) has become epidemic. OBJECTIVE We conducted a timely systematic review to examine the impact of tobacco and ENDS use on post-operative health outcomes among MBS patients. METHODS PRISMA guidelines were used as the search framework. Keyword combinations of either "smoking," "tobacco," "e-cigarette," "vaping," or "ENDS" and "bariatric surgery," "RYGB," or "sleeve gastrectomy" were used as search terms in PUBMED, Science Direct, and EMBASE. Studies published in English between January 1990 and June 2020 were screened. RESULTS From the 3251 articles found, a total of 48 articles were included in the review. No articles described a relationship between ENDS and post-operative health outcomes in MBS patients. Seven studies reported smokers had greater post-MBS weight loss, six studies suggested no relationship between smoking and post-MBS weight loss, and one study reported smoking cessation pre-MBS was related to post-MBS weight gain. Perioperative use of tobacco is positively associated with several post-surgery complications and mortality in MBS patients. CONCLUSIONS Combustible tobacco use among MBS patients is significantly related to higher mortality risk and complication rates, but not weight loss. No data currently is available on the impact of ENDS use in these patients. With ENDS use at epidemic levels, it is imperative to determine any potential health effects among patients with severe obesity, and who complete MBS.

Abstract
Diabetes Mellitus is characterized by numerous metabolic disorders, which have in common the serum elevation of glucose, caused for a pancreatic malfunction in insulin secretion and / or its action. It is a non-communicable disease, considered major public health problems and generalized growth worldwide, being a chronic disease, which can generate a high treatment cost. Metabolic surgery is a safe treatment, regulated by the Federal Council of Medicine and useful in treating people with BMI over 30 years of age, who are unable to control pathologies associated with obesity, primarily type 2 diabetes. The general objective of this study is to understand through a literature review the main impacts of metabolic surgery about the remission of DM 2. This present study it is an exploratory and descriptive study carried out through a literature review. Data were collected through research in virtual health databases, at the Virtual Health Library - VHL, Latin American and Caribbean Health Sciences Information System, LILACS, National Library of Medicine - MEDLINE, Scielo, USP database, PUBMED theses and books. Metabolic surgery proof be a good and effective treatment for having and maintaining good weight loss, as well as a significant clinical and metabolic improvement that extends beyond weight loss. Metabolic surgery is a satisfactory way of achieving long-term weight reduction in obese individuals, increasing survival for these patients. Obese patients with DM2 have a long-term remission of DM2 after bariatric / metabolic surgery. Therefore, it concludes that such procedure is effective in the treatment of the disease and other diseases associated with obesity.

The Use of Visceral Adiposity Index to Predict Diabetes Remission in Low BMI Chinese Patients After Bariatric Surgery. Obes Surg 2020; 31:805-812. [PMID: 33063158 DOI: 10.1007/s11695-020-05034-w] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2020] [Revised: 10/01/2020] [Accepted: 10/06/2020] [Indexed: 12/17/2022]
Abstract
BACKGROUND Visceral Adiposity Index (VAI) is considered to be a reliable indicator for evaluation of visceral adipose dysfunction and cardiovascular disease risk. However, no previous studies have reported the VAI variation after bariatric surgery and the predictive effect of preoperative VAI on diabetes remission. The aim of this study is to evaluate whether preoperative VAI is useful to predict diabetes remission in low BMI Chinese patients after bariatric surgery. METHODS Eighty-seven type 2 diabetes mellitus patients with BMI < 35 kg/m2 underwent bariatric surgery from May 2010 to March 2018 in our hospital. VAI, glycolipid metabolic parameters, and anthropometric variables were measured before and 4 years after surgery. Complete remission was defined as follows: HbA1c < 6%, FPG < 5.6 mmol/L, achieved without anti-diabetic medication. Analysis included using binary logistic regression to identify predictors and ROC curves to determine clinically useful cutoff values. RESULTS Seventy-four patients (85.1%) underwent Roux-en-Y gastric bypass (RYGB), while the remaining 13 patients (14.9%) underwent sleeve gastrectomy (SG). Patients' weight, glycemic control, and lipid profiles were improved significantly after surgery (p < 0.05). Complete remission of T2DM was found in 35 patients (40.2%) 1 year after surgery. VAI decreased from baseline 4.41 to 1.74 in 3 months after surgery (p < 0.05) and showed a downward trend over the period from 6 months to 4 years. Patients with complete remission had a significantly shorter duration of diabetes, lower HbA1c level, and higher VAI, in comparison to those without remission. Binary logistics regression and ROC curves analysis confirm that VAI, HbA1c, and duration of diabetes can predict diabetes remission after bariatric surgery, and the VAI of 4.46 is a useful threshold for predicting surgical efficacy. CONCLUSION VAI is a significant predictor of diabetes remission for lower BMI patients with T2DM following bariatric surgery in China. The VAI of 4.46 is a useful threshold for predicting surgical efficacy. Multi-center and larger prospective studies are needed to confirm our findings.

Janik MR, Aryaie AH. The effect of smoking on bariatric surgical 30-day outcomes: propensity-score-matched analysis of the MBSAQIP. Surg Endosc 2020; 35:3905-3914. [PMID: 32728767 PMCID: PMC8195797 DOI: 10.1007/s00464-020-07838-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Accepted: 07/22/2020] [Indexed: 12/04/2022]
Abstract
Background The exact impact of smoking within the last 12 months on the safety outcome of sleeve gastrectomy and Roux-Y gastric bypass is not well known. The study aimed to assess the effects of smoking on 30-day surgical outcomes. Methods Preoperative characteristics and outcomes from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program dataset 2015–2018 were selected for all patients who underwent primary sleeve gastrectomy or Roux-Y gastric bypass. 30-day postoperative outcomes were assessed. We used propensity score matching to control for potential confounding. Results In laparoscopic sleeve gastrectomy group, 29 165 pairs were included in the analysis. Smoking increased risk for inpatients readmission rate (3.67% vs. 3.10%; RR, 1.18; 95%CI 1.08–1.29, p < 0.001), intervention rate (1.03% vs. 0.84%; RR, 1.22; 95%CI 1.00–1.24, p = 0.020), reoperation rate (0.99% vs. 0.79%; RR, 1.25; 95%CI 1.05–1.48, p = 0.010), and leak rate (0.59% vs. 0.32%; RR, 1.83; 95%CI 1.43–2.37, p < 0.001). In laparoscopic Roux-Y gastric bypass cohort,11 895 pairs were included in the ultimate analysis. Smoking increased risk for inpatients readmission rate (7.54% vs. 5.88%; RR, 1.28; 95%CI 1.16–1.41, p < 0.001), intervention rate (3.53% vs. 2.30%; RR, 1.54; 95%CI 1.32–1.80, p < 001), reoperation rate (3.17% vs. 1.86%; RR, 1.70; 95%CI 1.45–2.00, p < 0.001), leak rate (1.05% vs. 0.59%; RR, 1.78; 95%CI 1.33–2.39, p < 0.001), bleed rate (2.03% vs. 1.45%; RR, 1.39; 95%CI 1.15–1.69, p < 0.001), and morbidity (4.20% vs. 3.38%; RR, 1.24; 95%CI 1.09–1.41, p = 0.001). Conclusion Smoking cigarettes at any point within the 12 months before admission for surgery increased the risk for surgical short-term complications in bariatric patients. The effect was the most significant regarding leaks.

Abstract
BACKGROUND Outcomes after bariatric surgery are tied to surgical volume; however, this relationship is not clearly established for each procedure. OBJECTIVES To evaluate the impact of surgeon/hospital volumes on morbidity after bariatric surgery and identify volume cutoffs. SETTING Multi-centric population-level study, province of Quebec, Canada. METHODS We studied a population-based cohort of all morbidly obese patients who underwent bariatric surgery in Quebec, Canada during 2006 to 2012. We evaluated only the most common procedures in North America, Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG). Multilevel, cross-classified logistic regressions were used to test the effects of annual surgeon volume (SV) and hospital volume (HV) on a composite 90-day postoperative outcome. Receiver operator curve was used to identify volume thresholds. RESULTS Overall, 821 patients had RYGB and 1802 underwent SG by 34 surgeons in 15 centers. For RYGB, 10-case increase in SV was associated with adjusted odds ratio of .82 (95% confidence interval: .71-.94). Similar increase in HV resulted in odds ratio of .86 (95% confidence interval: .77-.96). Annual SV threshold of 21 RYGBs and HV of 25 cases were identified (area under the curve = .60 and .61, respectively). For SV, being in the higher volume category translated into an absolute risk reduction of 12.5% for 90-day major morbidity. For SG, annual 10-case increase in SV and HV was not significantly associated with a decrease in 90-day postoperative morbidity. CONCLUSION SV and HV are significant independent predictors of 90-day major morbidity after RYGB. This study further supports establishing minimum surgical volume requirements for more complex anastomotic procedures like RYGB. However, the role of volume targets in SG remains unclear.

Abstract
BACKGROUND Criteria for undergoing sleeve gastrectomy (SG) is restricted among patients with a body mass index (BMI) <35 kg/m2. OBJECTIVES To determine if low-BMI patients experience similar health benefits after SG compared with patients with a BMI ≥35 kg/m2. SETTING Teaching and nonteaching hospitals in Michigan. METHODS Patients with a BMI <35 kg/m2 at the time of primary SG were identified between 2006 and 2018 (n = 1073, 2.4%). Patient characteristics, 30-day risk-adjusted complication rates, and patient reported outcomes were compared with all patients who underwent SG with a BMI ≥35 kg/m2 (n = 44,511, mean BMI 46.7 kg/m2). RESULTS Low-BMI patients were more likely to be older (50.7 versus 45.4 yr, P < .0001), have diabetes (36.7 versus 30.9%, P < .0001), hypertension (54.2% versus 51.0%, P = .0372), and hyperlipidemia (57.1% versus 44.8%, P < .0001). Both groups had comparable rates of discontinuation of medications for hypertension (59.7% versus 54.1%, P = .0570), hyperlipidemia (54.3% versus 52.2%, P = .5537), and diabetes (oral, 79.2% versus 78.1%, P = .7294; insulin, 64.2% versus 62.2%, P = .7438). However, low-BMI patients were more likely to achieve a healthy BMI (i.e., BMI ≤25 kg/m2; 36.3% versus 6.01%, P < .0001), and had higher body image scores (50.6 versus 42.4, P < .0001). CONCLUSIONS Despite being older and with higher rates of metabolic disease, low-BMI patients reported high-resolution rates for diabetes, hypertension, and hyperlipidemia (>50%) and were more likely to achieve a healthy weight after SG. Abolishing the BMI threshold for SG among patients with metabolic disease should be considered.

Abstract
BACKGROUND Sleeve gastrectomy (SG) has been the most frequently performed bariatric procedure worldwide since 2014. Therefore, it is vital to look at its outcomes in a long-term follow-up based on a large patient collective. Main points of discussion are weight regain, reflux, and patients' quality of life at 10+ years after the procedure. OBJECTIVES The aim of this study is to present an update of data that have been published recently and, thus, achieve more conclusive results. The number of patients has been doubled, and the length of the follow-up is still 10+ years. SETTING Multi-center study, medical university clinic, Austria METHODS: This study includes all patients who had SG before December 2006 at the participating bariatric centers. At 10+ years, non-converted patients (67%) were examined using gastroscopy, manometry, 24-hour pH-metry, and questionnaires. Patients' history of weight, comorbidities, and reflux were established through interviews. RESULTS At 10+ years after SG, the authors found a conversion rate of 33%, an %EWL in non-converted patients of 50.0 ± 22.5, reflux in 57%, and Barrett's metaplasia in 14% of non-converted patients. Gastroscopies revealed that patients with reflux were significantly more likely to have de-novo hiatal hernia. A significantly lower quality of life was detected through GIQLI and BAROS in patients with reflux. CONCLUSION The authors recommend gastroscopies at 5-year intervals after SG to detect the possible sequelae of reflux at an early stage. Conversion to Roux-en-Y-gastric bypass (RYGB) works well to cure patients from reflux but may not be as efficient at treating weight regain.

Abstract
Despite the effectiveness of bariatric surgery, both with respect to weight loss and improvements in obesity-related co-morbidities, it remains underused. Only 1% of the currently eligible population undergoes surgical treatment for obesity, with roughly 228,000 individuals receiving bariatric surgery in the United States each year. Several barriers to bariatric surgery have been identified, including limited patient and referring physician knowledge and attitudes regarding the effectiveness and safety of bariatric surgery. However, the role of insurance coverage and benefit design as a barrier to access to care has received less attention to date. Bariatric surgery is cost-effective compared with nonsurgical treatments among individuals with extreme obesity and type 2 diabetes. While it may not result in cost savings among all bariatric surgery eligible patients, for certain patient subgroups, bariatric surgery may be cost neutral compared with traditional treatment options. In addition, longer-term outcomes of bariatric surgery suggest decreased or stable costs in the long run. The purpose of this review paper was to synthesize the existing knowledge on why bariatric surgery remains largely underused in the United States with a focus on health insurance benefits and design. In addition, the review discusses the applicability of value-based insurance design to bariatric surgery. Value-based insurance design has been previously applied to bariatric surgery coverage with use of incentive-based cost-sharing adjustments. Its application could be further extended because the postoperative clinical outcomes and costs vary among the different subgroups of bariatric surgery eligible patients.

Abstract
Purpose Vertical sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) are currently the most common bariatric procedures. Although the safety of these operations has markedly improved, there continues to be a certain rate of complications. Such adverse events can have a significant deleterious effect on the outcome of these procedures and represent a costly burden on patients and society at large. A better understanding of these complications and their predictive factors may help ameliorate and optimize outcomes. Methods Seven hundred seventy-two consecutive patients who underwent SG or RYGB for morbid obesity between January 2011 and October 2015, in the Division of Bariatric Surgery at a tertiary institution, were included through retrospective review of the medical database. The complications were categorized and evaluated according to severity using the Clavien-Dindo classification system. Significant risk factors were evaluated by binary logistic regression to identify independent predictors and analyzed to identify their relationship with the type of complication. Results Independent predictors of severe complication after these procedures included male gender, open and revisional surgery, hypertension, and hypoalbuminemia. Hypoalbuminemia had significant associations with occurrence of deep surgical site infection and leak. Open surgery had significant associations with occurrence of superficial and deep surgical site infection and respiratory complications. Independent predictors of severe complication after laparoscopic primary RYGB included previous abdominal surgery. Previous abdominal surgery had significant associations with deep surgical site infection and leak. Conclusion Recognition and optimization of these risk factors would be valuable in operative risk prediction before bariatric surgery.

Abstract
Background: Obesity is a global health epidemic and is associated with many maternal and neonatal complications. Laparoscopic sleeve gastrectomy (LSG) is among the surgical treatments for obesity. The appropriate timing of pregnancy following LSG remains controversial and few studies have evaluated this public health issue. Objective: To evaluate the effect of pregnancy timing after LSG on maternal and perinatal outcomes. Study design: We performed a retrospective observational study of 23 pregnant women who underwent LSG at a tertiary hospital in Turkey. Women who became pregnant within 18 months of undergoing LSG were included in the early pregnancy after LSG group, and those who became pregnant after 18 months were included the late pregnancy after LSG group. Maternal and perinatal outcomes were evaluated, including gestational diabetes mellitus (GDM), pregnancy-associated hypertensive disorders, preterm birth, mode of delivery, small and large for gestational age births (small for gestational age (SGA), large for gestational age (LGA)), birth injury, and congenital malformations. Results: Body mass index (BMI) at conception was higher in the early pregnancy after LSG group than in the late pregnancy after LSG group (30.48 versus 27.25, respectively; p = .03). Pregnancy interval after LSG did not impact maternal-fetal complications or mode of delivery. After a 75 g oral glucose tolerance test (OGTT) for GDM, 75% (n = 6) of the early pregnancy group presented with early dumping syndrome, compared to only 13.3% (n = 2) of the late pregnancy after LSG group (p = .009). Conclusions: LSG may reduce obesity-related gestational complications, such as GDM and LGA. The interval between LSG and conception did not impact maternal or neonatal outcomes. Screening for GDM can result in dumping syndrome in pregnancies after LSG.

Abstract
INTRODUCTION The aim of this study was to assess the incidence, clinical presentation, and outcomes of neurologic disorders secondary to vitamin B deficiencies following bariatric surgery. METHODS Patients at a single academic institution who underwent bariatric surgery and developed neurologic complications secondary to low levels of vitamins B1, B2, B6, and B12 between the years 2004 and 2015 were studied. RESULTS In total, 47 (0.7%) bariatric surgical patients (Roux-en-Y gastric bypass n = 36, sleeve gastrectomy n = 9, and duodenal switch n = 2) developed neurologic manifestations secondary to vitamin B deficiencies. Eleven (23%) patients developed postoperative anatomical complications contributed to poor oral intake. Median duration to onset of neurologic manifestation following surgery was 12 months (IQR, 5-32). Vitamin deficiencies reported in the cohort included B1 (n = 30), B2 (n = 1), B6 (n = 12), and B12 (n = 12) deficiency. The most common manifestations were paresthesia (n = 31), muscle weakness (n = 15), abnormal gait (n = 11), and polyneuropathy (n = 7). Four patients were diagnosed with Wernicke-Korsakoff syndrome (WKS) which was developed after gastric bypass (n = 3) and sleeve gastrectomy (n = 1). Seven patients required readmission for management of severe vitamin B deficiencies. Overall, resolution of neurologic symptoms with nutritional interventions and pharmacotherapy was noted in 40 patients (85%). The WKS was not reversible, and all four patients had residual mild ataxia and nystagmus at the last follow-up time. CONCLUSIONS Nutritional neurologic disorders secondary to vitamin B deficiency are relatively uncommon after bariatric surgery. While neurologic disorders are reversible in most patients (85%) with vitamin replacements, persistent residual neurologic symptoms are common in patients with WKS.

[PMID: 29503096 DOI: 10.1016/j.soard.2018.01.008] [Citation(s) in RCA: 58] [Impact Index Per Article: 9.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2017] [Revised: 12/19/2017] [Accepted: 01/08/2018] [Indexed: 12/17/2022]
Abstract
BACKGROUND National quality programs have been implemented to decrease the burden of adverse events on key outcomes in bariatric surgery. However, it is not well understood which complications have the most impact on patient health. OBJECTIVE To quantify the impact of specific bariatric surgery complications on key clinical outcomes. SETTING The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. METHODS Data from patients who underwent primary bariatric procedures were retrieved from the MBSAQIP 2015 participant use file. The impact of 8 specific complications (bleeding, venous thromboembolism [VTE], leak, wound infection, pneumonia, urinary tract infection, myocardial infarction, and stroke) on 5 main 30-day outcomes (end-organ dysfunction, reoperation, intensive care unit admission, readmission, and mortality) was estimated using risk-adjusted population attributable fractions. The population attributable fraction is a calculated measure taking into account the prevalence and severity of each complication. The population attributable fractions represents the percentage reduction in a given outcome that would occur if that complication were eliminated. RESULTS In total, 135,413 patients undergoing sleeve gastrectomy (67%), Roux-en-Y gastric bypass (29%), adjustable gastric banding (3%), and duodenal switch (1%) were included. The most common complications were bleeding (.7%), wound infection (.5%), urinary tract infection (.3%), VTE (.3%), and leak (.2%). Bleeding and leak were the largest contributors to 3 of 5 examined outcomes. VTE had the greatest effect on readmission and mortality. CONCLUSION This study quantifies the impact of specific complications on key surgical outcomes after bariatric surgery. Bleeding and leak were the complications with the largest overall effect on end-organ dysfunction, reoperation, and intensive care unit admission after bariatric surgery. Furthermore, our findings suggest that an initiative targeting reduction of post-bariatric surgery VTE has the greatest potential to reduce mortality and readmission rates.

Abstract
BACKGROUND The current literature comparing robot-assisted Roux-en-Y gastric bypass (RA-RYGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB) is limited to single center retrospective series. OBJECTIVES This study aims to compare perioperative outcomes of patients who underwent RA-RYGB with those who underwent LRYGB. SETTING National database. METHODS Data on patients who underwent RA-RYGB and LRYGB were extracted from the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program participant use file. A 1:8 propensity score matching (RA-RYGB:LRYGB) was performed, and the 30-day outcomes of the propensity-matched cohorts were compared. RESULTS In total, 36,158 patients met inclusion criteria, including 2660 RA-RYGB (7.4%) cases, which were propensity matched (1:8) with 21,280 LRYGB cases having similar preoperative characteristics. RA-RYGB was associated with longer median operative time (136 versus 107 min; P<.001) and a higher 30-day readmission rate (7.3% versus 6.2%; P = .03). There were no statistical differences between the RA-RYGB and LRYGB cohorts with respect to all-cause morbidity (10.6% versus 10.7%; P = .8), serious morbidity (1.2% versus 1.7%; P = .07), mortality (0.1% versus .2%; P = .2), unplanned intensive care unit admission (1.1% versus 1.3%; P = .3), reoperation (2.4% versus 2.4%; P = .97), or reintervention (3.0% versus 2.5%; P = .2) within 30 days after surgery. CONCLUSION Based on available national data, RA-RYGB appears safe compared with a conventional laparoscopic approach for gastric bypass. However, RA-RYGB was associated with longer operative time and higher readmission rate, indicating greater resource use. Further studies are needed to better delineate the role of robotic platforms in bariatric surgery.

Abstract
OBJECTIVE To construct and validate a scoring system for evidence-based selection of bariatric and metabolic surgery procedures according to severity of type 2 diabetes (T2DM). BACKGROUND Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) account for >95% of bariatric procedures in United States in patients with T2DM. To date, there is no validated model to guide procedure selection based on long-term glucose control in patients with T2DM. METHODS A total of 659 patients with T2DM who underwent RYGB and SG at an academic center in the United States and had a minimum 5-year follow-up (2005-2011) were analyzed to generate the model. The validation dataset consisted of 241 patients from an academic center in Spain where similar criteria were applied. RESULTS At median postoperative follow-up of 7 years (range 5-12), diabetes remission (HbA1C <6.5% off medications) was observed in 49% after RYGB and 28% after SG (P < 0.001). Four independent predictors of long-term remission including preoperative duration of T2DM (P < 0.0001), preoperative number of diabetes medications (P < 0.0001), insulin use (P = 0.002), and glycemic control (HbA1C < 7%) (P = 0.002) were used to develop the Individualized Metabolic Surgery (IMS) score using a nomogram. Patients were then categorized into 3 stages of diabetes severity. In mild T2DM (IMS score ≤25), both procedures significantly improved T2DM. In severe T2DM (IMS score >95), when clinical features suggest limited functional β-cell reserve, both procedures had similarly low efficacy for diabetes remission. There was an intermediate group, however, in which RYGB was significantly more effective than SG, likely related to its more pronounced neurohormonal effects. Findings were externally validated and procedure recommendations for each severity stage were provided. CONCLUSIONS This is the largest reported cohort (n = 900) with long-term postoperative glycemic follow-up, which, for the first time, categorizes T2DM into 3 validated severity stages for evidence-based procedure selection.

Outcomes after bariatric surgery according to large databases: a systematic review. Langenbecks Arch Surg 2017; 402:885-899. [PMID: 28780622 DOI: 10.1007/s00423-017-1613-6] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Accepted: 07/27/2017] [Indexed: 12/29/2022]
Abstract
PURPOSE The rapid development of technological tools to record data allows storage of enormous datasets, often termed "big data". In the USA, three large databases have been developed to store data regarding surgical outcomes: the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP), the Healthcare Cost and Utilization Project (HCUP) National Inpatient Sample (NIS) and the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP). We aimed to evaluate the clinical impact of studies found in these databases concerning outcomes of bariatric surgery. METHODS We performed a systematic review using the Meta-analysis of Observational Studies in Epidemiology guidelines. Research carried out using the PubMed database identified 362 papers. All outcomes related to bariatric surgery were analysed. RESULTS Fifty-four studies, published between 2005 and February 2017, were included. These articles were divided into (1) outcomes related to surgical techniques (12 articles), (2) morbidity and mortality (12), (3) 30-day hospital readmission (10), (4) outcomes related to specific diseases (11), (5) training (2) and (6) socio-economic and ethnic observations in bariatric surgery (7). Forty-two papers were based on data from ACS-NSQIP, nine on data from NIS and three on data from MBSAQIP. CONCLUSIONS This review provides an overview of surgical management and outcomes of bariatric surgery in the USA. Large databases offer useful complementary information that could be considered external validation when strong evidence-based medicine data are lacking. They also allow us to evaluate infrequent situations for which randomized control trials are not feasible and add specific information that can complement the quality of surgical knowledge.

Abstract
Metabolic and bariatric surgery (MBS) leads to weight loss in obese individuals and reduces comorbidities such as type 2 diabetes. MBS is superior to medical therapy in reducing hyperglycemia in persons with type 2 diabetes, and has been associated with reduced mortality and incidences of cardiovascular events and cancer in obese individuals. New guidelines have been proposed for the use of MBS in persons with type 2 diabetes. We review the use of MBS as a treatment for obesity and obesity-related conditions and, based on recent evidence, propose that health care systems make the appropriate changes to increase accessibility for eligible patients.

Surg Obes Relat Dis 2017; 13:1212-1226. [PMID: 28366671 DOI: 10.1016/j.soard.2017.02.010] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2016] [Revised: 02/07/2017] [Accepted: 02/09/2017] [Indexed: 02/06/2023]
Abstract
BACKGROUND The duodenum plays a role in the mechanism of type 2 diabetes remission after bariatric surgery. Roux-en-Y gastric bypass (RYGB) may change gene expression in the duodenum and metabolism. Long noncoding RNAs (lncRNAs) constitute a novel class of RNAs that regulate gene expression. Little is known about how duodenal lncRNAs respond to RYGB. Logically, studies on the changes of duodenal lncRNAs potentially can lead to an understanding of the mechanisms of bariatric surgery, as well as discovery of antidiabetic drug targets and biomarkers predicting postoperative outcome. OBJECTIVES To investigate the expression signature of duodenal lncRNAs associated with glycemic improvement by duodenal-jejunal bypass (DJB), a component of RYGB, on a genome-wide scale in high-fat diet-induced diabetic mice. SETTING University medical center. METHODS High fat diet-induced diabetic mice were randomized into 2 groups receiving either the DJB or a sham procedure. Microarray was applied to screen the differentially expressed lncRNAs and messenger RNAs (mRNAs) in the duodenum between the DJB and sham groups, and the result was validated by quantitative real-time polymerase chain reaction in another cohort of animals. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analyses were performed to predict the potential lncRNA functions. Based on Pearson correlation analysis, the lncRNA-mRNA and lncRNA-transcription factor (TF) interaction networks were constructed to identify and rank core regulatory lncRNAs and transcription factors. RESULTS A total of 301 lncRNAs, including 232 that were upregulated and 69 downregulated (fold change≥2.0), were differentially expressed in the duodenum between the DJB and sham groups. GO enrichment indicated that these lncRNA-coexpressed mRNAs were correlated with biological processes including cell proliferation, digestion, and catabolic and biosynthetic processes. KEGG pathway analysis revealed that in addition to the digestion and absorption signaling pathways, pancreatic secretion- and inflammatory process-related signaling pathways were mostly enriched in the DJB group. In addition, the lncRNA-mRNA interaction network combined with GO and KEGG pathway analysis suggested that as a top-ranked gene, NONMMUG021726 may play an important role in the mechanism of type 2 diabetes remission after DJB. CONCLUSION DJB leads to drastic changes in lncRNA and mRNA expressions in the duodenum. The majority of top-ranked lncRNAs and mRNAs have roles in pancreatic secretion and inflammatory processes, implying that bypass of the duodenum may initiate insulin secretion and attenuate inflammation. In addition, modulators of such lncRNAs, most likely NONMMUG021726, have potential to become therapeutic targets or biomarkers for prediction of the outcomes of bariatric surgery.
