World J Gastrointest Surg 2024; 16:1320-1327. [PMID: 38817287 PMCID: PMC11135298 DOI: 10.4240/wjgs.v16.i5.1320] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/19/2024] [Revised: 04/02/2024] [Accepted: 04/09/2024] [Indexed: 05/23/2024] Open
Abstract
BACKGROUND Surgery for obese patients carries a higher risk of anesthesia complications compared with surgery for nonobese patients. Thus, a safe and effective anesthesia strategy is necessary to improve the medical experience of such patients and ensure their safety. AIM To compared the effectiveness and safety of remimazolam besylate versus dexmedetomidine (DEX) in gastrointestinal surgery in obese patients. METHODS The study cohort included 60 obese patients undergoing gastrointestinal surgery between July 2021 and April 2023, comprising 30 patients who received DEX intervention (control group) and 30 patients who received remimazolam besylate intervention (research group). Heart rate (HR), respiratory rate (RR), mean arterial pressure (MAP), blood oxygen saturation (SpO2), safety (nausea and vomiting, bradycardia, hypotension, and apnea), anesthesia and examination indices [induction time, anesthesia recovery time, and postanesthesia care unit (PACU) discharge time], sedation effect (Ramsay Sedation Scale), and postoperative pain visual analog scale were comparatively analyzed before anesthesia (T0), during anesthesia (T1), and after anesthesia (T2). RESULTS At T1, the research group showed significantly smaller changes in HR, RR, MAP, and SpO2 than the control group, with a significantly lower adverse reaction rate and shorter induction, anesthesia recovery, and PACU discharge times. Additionally, the intra- and postoperative Ramsay Sedation Scale scores were statistically higher in the research group than in the control group. CONCLUSION Remimazolam besylate was significantly more effective than DEX in gastrointestinal surgery in obese patients and had a higher safety profile and value in clinical promotion.

Abstract
This umbrella review amalgamates the outcomes of economic evaluations pertaining to bariatric surgeries, pharmacotherapy, and gastric balloon for adult obesity treatment. Six databases were systematically searched. The inclusion criteria were established following the Patient/population Intervention Comparison and Outcomes (PICO) statement. Fifteen reviews met all the inclusion criteria. Eight studies focused on surgical interventions, four on pharmacotherapy, and three on both interventions. No systematic review of the economic evaluation of gastric balloons was identified. The majority of reviews advocated bariatric surgery as a cost-effective approach; however, there was discordance in the interpretation of pharmacological cost-effectiveness. Most of the economic evaluations were conducted from the payer and the healthcare system perspectives. We propose that future economic evaluations assessing weight loss interventions in adults adopt a societal perspective and longer-term time horizons.

Predicting short-term thromboembolic risk following Roux-en-Y gastric bypass using supervised machine learning. World J Gastrointest Surg 2024; 16:1097-1108. [PMID: 38690043 PMCID: PMC11056662 DOI: 10.4240/wjgs.v16.i4.1097] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/07/2024] [Accepted: 03/05/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND Roux-en-Y gastric bypass (RYGB) is a widely recognized bariatric procedure that is particularly beneficial for patients with class III obesity. It aids in significant weight loss and improves obesity-related medical conditions. Despite its effectiveness, postoperative care still has challenges. Clinical evidence shows that venous thromboembolism (VTE) is a leading cause of 30-d morbidity and mortality after RYGB. Therefore, a clear unmet need exists for a tailored risk assessment tool for VTE in RYGB candidates. AIM To develop and internally validate a scoring system determining the individualized risk of 30-d VTE in patients undergoing RYGB. METHODS Using the 2016-2021 Metabolic and Bariatric Surgery Accreditation Quality Improvement Program, data from 6526 patients (body mass index ≥ 40 kg/m2) who underwent RYGB were analyzed. A backward elimination multivariate analysis identified predictors of VTE characterized by pulmonary embolism and/or deep venous thrombosis within 30 d of RYGB. The resultant risk scores were derived from the coefficients of statistically significant variables. The performance of the model was evaluated using receiver operating curves through 5-fold cross-validation. RESULTS Of the 26 initial variables, six predictors were identified. These included a history of chronic obstructive pulmonary disease with a regression coefficient (Coef) of 2.54 (P < 0.001), length of stay (Coef 0.08, P < 0.001), prior deep venous thrombosis (Coef 1.61, P < 0.001), hemoglobin A1c > 7% (Coef 1.19, P < 0.001), venous stasis history (Coef 1.43, P < 0.001), and preoperative anticoagulation use (Coef 1.24, P < 0.001). These variables were weighted according to their regression coefficients in an algorithm that was generated for the model predicting 30-d VTE risk post-RYGB. The risk model's area under the curve (AUC) was 0.79 [95% confidence interval (CI): 0.63-0.81], showing good discriminatory power, achieving a sensitivity of 0.60 and a specificity of 0.91. Without training, the same model performed satisfactorily in patients with laparoscopic sleeve gastrectomy with an AUC of 0.63 (95%CI: 0.62-0.64) and endoscopic sleeve gastroplasty with an AUC of 0.76 (95%CI: 0.75-0.78). CONCLUSION This simple risk model uses only six variables to assist clinicians in the preoperative risk stratification of RYGB patients, offering insights into factors that heighten the risk of VTE events.

Abstract
Obesity has become a global epidemic in the modern world, significantly impacting the global healthcare economy. Lifestyle interventions remain the primary approach to managing obesity, with medical therapy considered a secondary option, often used in conjunction with lifestyle modifications. In recent years, there has been a proliferation of newer therapeutic agents, revolutionizing the treatment landscape for obesity. Notably, glucagon-like peptide-1 receptor agonists (GLP-1 RAs), such as semaglutide, liraglutide, and the recently approved dual GLP-1/GIP RAs agonist tirzepatide, have emerged as effective medications for managing obesity, resulting in significant weight loss. These agents not only promote weight reduction but also improve metabolic parameters, including lipid profiles, glucose levels, and central adiposity. On the other hand, bariatric surgery has demonstrated superior efficacy in achieving weight reduction and addressing overall metabolic imbalances. However, with ongoing technological advancements, there is an ongoing debate regarding whether personalized medicine, targeting specific components, will shape the future of developing novel therapeutic agents for obesity management.

Abstract
BACKGROUND Metabolic bariatric surgery (MBS) not only leads to a durable weight loss but also lowers mortality, and reduces cardiovascular risks. OBJECTIVES The current study aims to investigate the association of bariatric metabolic surgery (BMS) with admissions for acute myocardial infarction (AMI), including ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), as well as, coronary revascularization procedures, including percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and thrombolysis. SETTING The National Inpatient Sample (NIS) database. METHODS The NIS data from 2016 to 2020 were analyzed. A propensity score matching in a 1:1 ratio was performed to match patients with history of MBS with non-MBS group. RESULTS Two hundred thirty-three thousand seven hundred twenty-nine patients from the non-MBS group were matched with 233,729 patients with history of MBS. The MBS group had about 52% reduced odds of admission for AMI compared to the non-MBS group (adjusted odd ratio: .477, 95% confidence interval: .454-.502, P value <.001). In addition, the odds of STEMI and NSEMI were significantly lower in the MBS group in comparison to the non-MBS group. Also, the MBS group had significantly lower odds of CABG, PCI, and thrombolysis compared to the non-MBS group. In addition, in patients with AMI, MBS was associated with lower in-hospital mortality (adjusted odd ratio: .627, 95% confidence interval: .469-.839, P value = .004), length of hospital stays, and total charges. CONCLUSIONS History of MBS is significantly associated with reduced risk of admission for AMI including STEMI and NSTEMI, as well as the, need for coronary revascularization such as PCI and CABG.

Abstract
This study aimed to examine the potential predictors of improvement in mental health outcomes following participation in an intensive non-surgical outpatient weight management program (WMP) in an Australian public hospital. This was a retrospective cohort study of all adults with Class 3 obesity (BMI ≥ 40 kg/m2) who enrolled in the WMP from March 2018 to June 2021. The participants completed the Eating Disorder Examination Questionnaire Short Version (EDE-QS), Kessler-10 Psychological Distress Scale, and 36-Item Short-Form Survey (SF-36) at baseline and 12-month follow-up. A total of 115 patients completed 12 months in the WMP and were included in the study, with 76.5% being female, a mean ± SD age at baseline of 51.3 ± 13.8 years, a weight of 146 ± 26 kg, and a BMI of 51.1 ± 8.6 kg/m2. The participants lost an average of 8.6 ± 0.2 kg over 12 months, and greater weight loss at follow-up was significantly associated with improved global EDE-QS scores, psychological distress, and improved mental health quality of life. However, improvements in most mental health outcomes were not predicted by weight loss alone. Notably, a lower eating disorder risk at baseline was associated with less psychological distress at follow-up and greater weight loss at follow-up. Our results also found an association between reduced psychological distress and reduced binge eating frequency. These findings support the inclusion components of obesity interventions that target the psychological correlates of obesity to support improved outcomes in people with Class 3 obesity. Future studies should aim to identify which aspects of the WMP helped improve people's psychological outcomes.

Abstract
BACKGROUND Obesity is a significant risk factor for osteoarthritis (OA). The most effective treatment for morbid obesity is bariatric surgery. PURPOSE To study the effects of potential surgically induced weight loss on knee articular cartilage and OA symptoms of obese patients over a 12-month follow-up. STUDY TYPE Prospective longitudinal cohort study. SUBJECTS 45 obese patients (38 female, BMI = 42.3 ± 6.5 kg/m2) who underwent gastric bypass (intervention group), and 46 age-matched conservative-care controls (37 female, BMI = 39.8 ± 4.6 kg/m2). FIELD STRENGTH/SEQUENCE Multiecho spin echo sequence at 3 T. ASSESSMENT Knee cartilage T2 measurements and WOMAC Indices were measured presurgery and after 12 months. The intervention group was split into successful (≥20% total weight loss (TWL)) and unsuccessful (<20% TWL) weight loss groups. T2 and WOMAC indices were also measured in controls at baseline and after 12 months. Changes among the three groups were analyzed. STATISTICAL TESTS Analysis of variance (significance level 0.05). RESULTS Twenty-six (58%) intervention patients achieved ≥20% TWL. The <20% TWL group demonstrated significantly more T2 reduction in the deep lateral femur over 12 months compared with the ≥20% TWL group (-3.83 ± 8.18 msec vs. 2.47 ± 6.54 msec, respectively), whereas no significant differences were observed on the medial femoral compartment (P = 0.385, P = 0.551, and P = 0.511 for bulk, superficial and deep regions, respectively). Changes in WOMAC indices over 12 months were significantly greater in the ≥20% TWL group compared with controls. In the <20% TWL group, pain significantly improved over 12 months compared with controls, while stiffness and function changes were not statistically significant (P = 0.063 and P = 0.051, respectively). DATA CONCLUSION Cartilage matrix, measured by T2, showed improvement on lateral femoral cartilage with <20% TWL compared with ≥20% TWL. Bariatric surgery provided significant improvements in knee symptoms with ≥20% TWL compared with conservative WL. This effect is also seen to some extent with <20% TWL compared with conservative WL. LEVEL OF EVIDENCE 2 TECHNICAL EFFICACY: Stage 4.

Abstract
OBJECTIVE The objective of this study was to compare the impact of sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) on overall and diabetes-specific health care costs among patients with type 2 diabetes. METHODS This retrospective cohort study examined patients with type 2 diabetes after SG and RYGB using data from Optum's deidentified Clinformatics® Data Mart database. The matched study group included 9608 patients who underwent SG or RYGB and were enrolled between 2007 and 2019. The primary outcomes assessed were overall and diabetes-specific health care costs. RESULTS Health care costs associated with type 2 diabetes declined substantially in the first few years following both SG and RYGB. RYGB was associated with a larger decrease in pharmacy costs, as well as type 2 diabetes-specific office and laboratory costs. SG was associated with lower total health care costs in the first three follow-up periods and lower acute care costs in the first 2 years after surgery. CONCLUSIONS In this nationwide study, patients with type 2 diabetes at baseline undergoing RYGB appear to experience a reduced need for ambulatory type 2 diabetes monitoring and reduced requirements for antidiabetes medication but, despite this, did not experience an overall medical cost-benefit in the first few years after RYGB versus SG.

Abstract
BACKGROUND The formulation of clinical recommendations pertaining to bariatric surgery is essential in guiding healthcare professionals. However, the extensive and continuously evolving body of literature in bariatric surgery presents considerable challenge for staying abreast of latest developments and efficient information acquisition. Artificial intelligence (AI) has the potential to streamline access to the salient points of clinical recommendations in bariatric surgery. OBJECTIVES The study aims to appraise the quality and readability of AI-chat-generated answers to frequently asked clinical inquiries in the field of bariatric and metabolic surgery. SETTING Remote. METHODS Question prompts inputted into AI large language models (LLMs) and were created based on pre-existing clinical practice guidelines regarding bariatric and metabolic surgery. The prompts were queried into 3 LLMs: OpenAI ChatGPT-4, Microsoft Bing, and Google Bard. The responses from each LLM were entered into a spreadsheet for randomized and blinded duplicate review. Accredited bariatric surgeons in North America independently assessed appropriateness of each recommendation using a 5-point Likert scale. Scores of 4 and 5 were deemed appropriate, while scores of 1-3 indicated lack of appropriateness. A Flesch Reading Ease (FRE) score was calculated to assess the readability of responses generated by each LLMs. RESULTS There was a significant difference between the 3 LLMs in their 5-point Likert scores, with mean values of 4.46 (SD .82), 3.89 (.80), and 3.11 (.72) for ChatGPT-4, Bard, and Bing (P < .001). There was a significant difference between the 3 LLMs in the proportion of appropriate answers, with ChatGPT-4 at 85.7%, Bard at 74.3%, and Bing at 25.7% (P < .001). The mean FRE scores for ChatGPT-4, Bard, and Bing, were 21.68 (SD 2.78), 42.89 (4.03), and 14.64 (5.09), respectively, with higher scores representing easier readability. CONCLUSIONS LLM-based AI chat models can effectively generate appropriate responses to clinical questions related to bariatric surgery, though the performance of different models can vary greatly. Therefore, caution should be taken when interpreting clinical information provided by LLMs, and clinician oversight is necessary to ensure accuracy. Future investigation is warranted to explore how LLMs might enhance healthcare provision and clinical decision-making in bariatric surgery.

Abstract
PURPOSE To develop the mapping functions from the Impact of Weight on Quality of Life-Lite (IWQOL-Lite) scores onto the EQ-5D-5L and SF-6Dv2 utility values among the overweight and obese population in China. METHODS A representative sample of the overweight and obese population in China stratified by age, sex, body mass index (BMI), and area of residence was collected by online survey and the sample was randomly divided into development (80%) and validation (20%) datasets. The conceptual overlap between the IWQOL-Lite and the EQ-5D-5L or SF-6Dv2 was evaluated by Spearman's correlation coefficients. Five models, including OLS, Tobit, CLAD, GLM, and PTM were explored to derive mapping functions using the development dataset. The model performance was assessed using MAE, RMSE, and the percentage of AE > 0.05 and AE > 0.1 in the validation dataset. RESULTS A total of 1000 respondents (48% female; mean [SD] age: 51.7 [15.3]; mean [SD] BMI: 27.4 [2.8]) were included in this study. The mean IWQOL-Lite scores and the utility values of EQ-5D-5L and SF-6Dv2 were 78.5, 0.851, and 0.734, respectively. The best-performing models predicting EQ-5D-5L and SF-6Dv2 utilities both used IWQOL-Lite total score as a predictor in the CLAD model (MAE: 0.083 and 0.076 for the EQ-5D-5L and SF-6Dv2; RMSE: 0.125 and 0.103 for the EQ-5D-5L and SF-6Dv2; AE > 0.05: 20.5% and 27.5% for the EQ-5D-5L and SF-6Dv2; AE > 0.10: 9.5% and 15.0% for the EQ-5D-5L and SF-6Dv2). CONCLUSION CLAD models with the IWQOL-Lite total score can be used to predict both the EQ-5D-5L and SF-6Dv2 utility values among overweight and obese population in China.

Prospective evaluation of transoral outlet reduction (TORe) after Roux-en-Y gastric bypass (RYGB) failure. Surg Endosc 2024; 38:1454-1464. [PMID: 38216748 DOI: 10.1007/s00464-023-10650-5] [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: 06/23/2023] [Accepted: 12/17/2023] [Indexed: 01/14/2024]
Abstract
BACKGROUND AND AIMS Weight regain after RYGB is multifactorial including dilatation of the gastro-jejunal anastomosis. Transoral outlet reduction (TORe) procedure is a minimally invasive alternative to surgical anastomotic revision. METHODS We conducted a prospective, multicenter, simple blind, randomized study in patients with weight regain following RYGB, comparing the efficacy of conventional nutritional and behavioral management associated with a TORe procedure (TORe group) with conventional management alone and a Sham procedure (Sham group). The main objective of this study was to evaluate the percentage of excess weight loss (%EWL) at 12 months after endoscopy. RESULTS From January 2015 to January 2019, 73 subjects were randomized in four French Bariatric centers. The final analysis involved 50 subjects, 25 in each group, 44 women, 6 men, with an average BMI of 40.6 kg/m2. At 12 months, the average %EWL was significantly higher in the TORe group than in the Sham group (13.5 ± 14.1 vs. - 0.77 ± 17.1; p = 0.002). Cohen's d was 0.91, indicating a large effect size of the procedure on the %EWL. There was no significant difference between groups concerning the improvement of obesity-related comorbidities (diabetes and dyslipidemia) and quality of life at 12 months. We report frequent adverse events in the TORe group (20% had adverse events related to the procedure). Three adverse events were serious, including two perforations of the gastro-jejunal anastomosis after TORe group that led to the premature termination of the study. CONCLUSIONS After RYGBP failure linked to the dilatation of the gastro-jejunal anastomosis, TORe procedure with nutritional management results in significantly higher %EWL at 12 months compared to patients with nutritional management alone. As surgery, this minimally invasive endoscopic procedure can be associated with severe adverse events.

Abstract
OBJECTIVES This scoping review informs a health economics perspective on the treatment of paediatric obesity. The results detail recently published research findings on the cost-effectiveness of paediatric obesity treatments and identify key characteristics of cost-effective interventions. METHODS A structured search was applied to six databases with no data restriction through March 2023: Medline, Embase, Cochrane CENTRAL, CINAHL, and PsycINFO. Studies that included a cost analysis of an individual level, weight management intervention (behavioural, pharmacotherapy, and surgical) in youth, with obesity, ages 2 to 21 years were eligible for inclusion. RESULTS Of the 4371 records identified in the initial search, 353 underwent full-text review, 39 studies met the pre-specified inclusion criteria. The majority were published after 2010 (n = 36/39, 92%) and applied to high-income countries (n = 39/39, 100%). Thirty-five of the studies assessed the cost-effectiveness of lifestyle interventions (90%), and four studies assessed surgical outcomes (10%). No pharmacotherapy studies met eligibility criteria. Although the outcome measures differed across the studies, all four surgical interventions were reported to be cost-effective. Thirty of the 35 (85%) lifestyle modification studies were reported to be cost-effective compared to the study comparator examined. CONCLUSIONS There is a small amount of evidence that individual-level paediatric obesity treatment interventions are cost-effective and, in some cases cost-saving, with most of this work conducted on behavioural interventions. The economic evaluation of paediatric obesity interventions poses various methodologic challenges, which should be addressed in future research to fully use the potential of economic evaluation as an aid to decision-making.

SF-6D Normative Values Among Patients Undergoing Bariatric Surgery: Results Based on Real-World Evidence from the Scandinavian Obesity Surgery Registry (SOReg). Obes Surg 2024; 34:558-567. [PMID: 38189900 PMCID: PMC10811135 DOI: 10.1007/s11695-023-07024-0] [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: 10/20/2023] [Revised: 12/18/2023] [Accepted: 12/19/2023] [Indexed: 01/09/2024]
Abstract
BACKGROUND The SF-6D index can be used to calculate quality-adjusted life years in economic evaluations, which is required by reimbursement agencies and national advisory bodies, including the Swedish ones. However, despite that SF-36 has been largely applied among patients undergoing bariatric surgery, almost no study has accessed the short form six-dimensions (SF-6D) after bariatric surgery. AIM To establish normative values for the SF-6D index among patients undergoing bariatric surgery. MATERIALS AND METHODS All patients who received bariatric surgery in Sweden between 2011-01-01 and 2019-03-31 were obtained from the Scandinavian Obesity Surgery Registry (SOReg). Information includes patients' sociodemographic characteristics, details regarding the procedure, and postsurgical conditions. The SF-36 is applied at baseline and at follow-up years 1, 2, and 5. The multiple sequential imputation method was applied to handle missingness on SF-6D items. Based on the UK tariff, the SF-6D preference scores were calculated. The normative values for the mean (SD) SF-6D index were reported by timepoint and surgical complications for men and women, respectively. Multivariate analyses were applied to investigate how the SF-6D index is associated with timepoint, controlling for age, sex, BMI, and comorbidities in a stepwise manner. RESULTS The SF-6D index increased at 1 year relative to baseline and was roughly maintained at the same level at 2 years. The normative value of the SF-6D index can be used in economic evaluations for bariatric surgery.

Abstract
BACKGROUND Bariatric surgery is a proven effective method of reducing obesity and reversing or preventing obesity-related comorbidities. The aim of this study is to describe the development of a tool to assist with the prioritization of patients with obesity for bariatric surgery. The tool would meet the criteria for being evidence-based, fair, implementable and transparent. METHODS The development of the tool involved a validated step-by-step process based on the consensus of clinical judgement of the New Zealand Ministry of Health working party. The process involved elicitation of criteria, clinical ranking of vignettes and creation of weightings using the 1000Minds® tool. The concurrent validity was tested by comparing tool rankings of vignettes to clinical judgement rankings. RESULTS Four major criteria (impact on life, likelihood of achieving maximum benefit with respect to control of diabetes, duration of benefit and surgical risk) are used to characterize the need and potential to benefit. The impact on life criterion has the largest weighting (up to 44.3%). There was good concurrent validity with a correlation coefficient r = 0.67. CONCLUSION The tool as presented is evidence-based, transparent and internally valid. The next step is to assess the predictive validity of the tool using real patient data to evaluate the effectiveness of the tool and determine what modifications may be required.

Abstract
The prevalence of overweight and obesity has more than doubled since 1980, and it is predicted that around two-thirds of the global burden of the disease will be attributed to chronic non-communicable diseases. Developing countries are experiencing a more dramatic rise in the prevalence of obesity in recent years. As per National Family Health Survey-5 (NFHS-5), one in every four Indians is now having obesity. It has been reported that being overweight and obese is a significant problem among different socioeconomic spectrums of men and women in India, especially among the elderly, people residing in urban regions, and diverse socioeconomic strata. There is an urgent need to identify obesity as a chronic disease requiring immediate attention, mandating timely screening, timely treatment, and economical ways of achieving and managing weight loss across the country. In this review, the authors have discussed various aspects of overweight and obesity and critically appraised the current status of obesity in India, its public health implications, the significance of screening, the role of BMI and other parameters in diagnosing obesity, and the need for treatment and cost-effective prescriptions.

Abstract
BACKGROUND Endoscopic sleeve gastroplasty (ESG) is a minimally invasive procedure that has been demonstrated in the MERIT randomised, controlled trial to result in substantial and durable additional weight loss in adults with obesity compared with lifestyle modification (LM) alone. We sought to conduct the first cost-effectiveness analysis of ESG versus LM alone in adults with class II obesity (BMI 35.0-39.9 kg/m2) from a national healthcare system perspective in England based on results from this study. METHODS A 6-state Markov model was developed comprising 5 BMI-based health states and an absorbing death state. Baseline characteristics, utilities, and transition probabilities were informed by patient-level data from the subset of patients with class II obesity in MERIT. Adverse events (AEs) were based on the MERIT safety population. Mortality was estimated by applying BMI-specific hazard ratios from the published literature to UK general population mortality rates. Utilities for the healthy weight and overweight health states were informed from the literature; disutility associated with increasing BMI in the class I-III obesity health states was estimated using MERIT utility data. Disutility due to AEs and the prevalence of obesity-related comorbidities were based on the literature. Costs included intervention costs, AE costs, and comorbidity costs. RESULTS ESG resulted in higher overall costs than LM alone but led to an increase in quality-adjusted life years (QALYs). The incremental cost-effectiveness ratio (ICER) for ESG vs LM alone was £2453/QALY gained. ESG was consistently cost effective across a wide range of sensitivity analyses, with no ICER estimate exceeding £10,000/QALY gained. In probabilistic sensitivity analysis, the mean ICER was £2502/QALY gained and ESG remained cost effective in 98.25% of iterations at a willingness-to-pay threshold of £20,000/QALY. CONCLUSION Our study indicates that ESG is highly cost effective versus LM alone for the treatment of adults with class II obesity in England.

Abstract
BACKGROUND Severe obesity could be an independent risk factor for peripheral artery disease (PAD) and critical limb ischemia (CLI). Bariatric surgery reduces cardiac risk factors, decreasing cardiovascular morbidity and mortality in subjects with severe obesity. OBJECTIVES We aimed to describe the impact of bariatric surgery on risk of hospitalization due to PAD and CLI. SETTING Academic hospital. METHODS The National Inpatient Sample data collected from 2010 to 2015 were examined. Patients were classified as treatment and control groups. Treatment was defined as patients with a previous history of bariatric surgery, and control was defined as patients with a body mass index ≥35 without a history of bariatric surgery. The primary outcome was hospitalization due to PAD; secondary outcomes were CLI, revascularization, major amputation, length of hospital stay (LOS), and total cost of hospitalization. Univariate and multivariate analyses were performed to assess the differences between groups. RESULTS There were a total of 2,300,845 subjects: 2,004,804 controls and 296,041 treatment patients. Hospitalization rate for PAD was significantly lower compared to the control group (.10% versus .21%, P < .0001), which was confirmed after adjusting for covariables (control versus treatment: odds ratio= 1.20, confidence interval: 1.15-1.47). Subgroup analysis showed patients without a history of bariatric surgery had a higher prevalence of CLI (59.3% versus 52.4%, P < .0219) and a higher mean LOS (6.7 versus 5.7 days, P = .0023) and cost of hospitalization (78.756 versus 72.621$, P = .0089), with no significant differences in other outcomes. After multivariate analysis, only LOS and total costs were significantly different. CONCLUSIONS Bariatric surgery may decrease the risk of hospitalization due to PAD, similarly to the LOS and total cost of hospitalization. Prospective studies should be performed to describe this relationship.

Front Endocrinol (Lausanne) 2023; 14:1228853.

Abstract
Background A 12-year study comparing clinical outcomes following Roux-en-Y bariatric surgery showed long-term weight loss with remission/prevention of type-2-diabetes (T2D), hypertension and dyslipidemia. However, it is unknown whether the underlying homeostatic metabolic processes involving hepatokines, adipokines and myokines also normalize. Using this 12-year study, we determined whether metabolic indices improved in post-surgical (BMI:34.4kg/m2) versus non-surgical comparator-subjects-with-obesity (BMI:43.8kg/m2) at 12-year follow-up (both cohorts with baseline diabetes), and if post-surgical subjects normalized their metabolic processes to those of a normal-weight cohort without diabetes. Methods Cross-sectional design. Plasma from a cohort of Roux-en-Y bariatric surgery (n=50) and non-surgery (n=76) comparator-subjects-with-obesity (both cohorts at 12-year follow-up) plus a normal-weight cohort (n=39) was assayed by Luminex immunoassay or ELISA for hepatokines [angiopoietin-like proteins-(ANGPTL3; ANGPTL4; ANGPTL6); fibroblast growth factors-(FGF19; FGF21; FGF23)]; adipokines [adipsin; adiponectin; FGF19] and myonectin. Results After age and gender adjustment, surgery versus comparator-subjects-with-obesity had lower BMI (34.4 ± 1.0 vs 43.8 ± 0.9kg/m2; p<0.0001), HbA1c (6.2 ± 0.3 vs 7.7 ± 0.2%; p<0.0001), insulin resistance (HOMA-IR, 2.0 ± 1.5 vs 10.8 ± 1.4; p<0.0001) fat mass (45.6 ± 2.2 vs 60.0 ± 2.0; p<0.0001), HDL-C (55.4 ± 2.6 vs 42.6 ± 2.3mg/dL; p<0.0001), triglycerides (130 ± 14 vs 187 ± 12mg/dL; p<0.0001) and higher adiponectin (25.9 ± 2.3 vs 15.7 ± 2.0µg/ml; p<0.001); Adipsin, ANGPTL3, ANGPTL4, ANGPTL6, FGF19, FGF21, FGF23 and myonectin did not differ. Surgery versus normal-weight group: higher ANGPTL4 (156 ± 6 vs 119 ± 7ng/mL; p<0.0001), higher FGF23 (96.4 ± 10.1 vs 50.9 ± 11.5pg/mL; p=0.007) and lower myonectin (744 ± 55 vs 969 ± 66ng/mL; p=0.002); adiponectin, adipsin ANGPTL3, ANGPTL6, FGF19, FGF21 did not differ. Non-surgery comparator-subjects-with-obesity versus normal-weight group: higher adipsin (1859 ± 94 vs 1314 ± 133ng/mL; p=0.0001), higher FGF23 (84.6 ± 8.5 vs 50.9 ± 11.5pg/mL; p<0.0001) and higher ANGPTL4 (171 ± 5 vs 119 ± 7ng/mL; p<0.0001); adiponectin ANGPTL3, ANGPTL6, FGF19, FGF21 and myonectin did not differ. Conclusion Bariatric surgery markedly improved anthropometric and metabolic features versus comparator-subjects-with-obesity at 12-year follow-up, indicating benefit of weight loss. However, despite weight loss, these patients still had class-1 obesity, as reflected in the adipokine, hepatokine and myokine markers of body homeostasis that did not completely normalize to indicative values of normal-weight subjects, suggesting either that this is the new normal for these patients or that weight loss to a BMI<25kg/m2 is needed for normalization of these parameters.

Access to publicly funded weight management services in England using routine data from primary and secondary care (2007-2020): An observational cohort study. PLoS Med 2023; 20:e1004282. [PMID: 37769031 PMCID: PMC10538857 DOI: 10.1371/journal.pmed.1004282] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/24/2023] [Accepted: 08/21/2023] [Indexed: 09/30/2023] Open
Abstract
BACKGROUND Adults living with overweight/obesity are eligible for publicly funded weight management (WM) programmes according to national guidance. People with the most severe and complex obesity are eligible for bariatric surgery. Primary care plays a key role in identifying overweight/obesity and referring to WM interventions. This study aimed to (1) describe the primary care population in England who (a) are referred for WM interventions and (b) undergo bariatric surgery and (2) determine the patient and GP practice characteristics associated with both. METHODS AND FINDINGS An observational cohort study was undertaken using routinely collected primary care data in England from the Clinical Practice Research Datalink linked with Hospital Episode Statistics. During the study period (January 2007 to June 2020), 1,811,587 adults met the inclusion criteria of a recording of overweight/obesity in primary care, of which 54.62% were female and 20.10% aged 45 to 54. Only 56,783 (3.13%) were referred to WM, and 3,701 (1.09% of those with severe and complex obesity) underwent bariatric surgery. Multivariable Poisson regression examined the associations of demographic, clinical, and regional characteristics on the likelihood of WM referral and bariatric surgery. Higher body mass index (BMI) and practice region had the strongest associations with both outcomes. People with BMI ≥40 kg/m2 were more than 6 times as likely to be referred for WM (10.05% of individuals) than BMI 25.0 to 29.9 kg/m2 (1.34%) (rate ratio (RR) 6.19, 95% confidence interval (CI) [5.99,6.40], p < 0.001). They were more than 5 times as likely to undergo bariatric surgery (3.98%) than BMI 35.0 to 40.0 kg/m2 with a comorbidity (0.53%) (RR 5.52, 95% CI [5.07,6.02], p < 0.001). Patients from practices in the West Midlands were the most likely to have a WM referral (5.40%) (RR 2.17, 95% CI [2.10,2.24], p < 0.001, compared with the North West, 2.89%), and practices from the East of England least likely (1.04%) (RR 0.43, 95% CI [0.41,0.46], p < 0.001, compared with North West). Patients from practices in London were the most likely to undergo bariatric surgery (2.15%), and practices in the North West the least likely (0.68%) (RR 3.29, 95% CI [2.88,3.76], p < 0.001, London compared with North West). Longer duration since diagnosis with severe and complex obesity (e.g., 1.67% of individuals diagnosed in 2007 versus 0.34% in 2015, RR 0.20, 95% CI [0.12,0.32], p < 0.001), and increasing comorbidities (e.g., 2.26% of individuals with 6+ comorbidities versus 1.39% with none (RR 8.79, 95% CI [7.16,10.79], p < 0.001) were also strongly associated with bariatric surgery. The main limitation is the reliance on overweight/obesity being recorded within primary care records to identify the study population. CONCLUSIONS Between 2007 and 2020, a very small percentage of the primary care population eligible for WM referral or bariatric surgery according to national guidance received either. Higher BMI and GP practice region had the strongest associations with both. Regional inequalities may reflect differences in commissioning and provision of WM services across the country. Multi-stakeholder qualitative research is ongoing to understand the barriers to accessing WM services and potential solutions. Together with population-wide prevention strategies, improved access to WM interventions is needed to reduce obesity levels.

Abstract
INTRODUCTION The vagus nerve has an important role in satiety, metabolism, and autonomic control in upper gastrointestinal function. However, the role and effects of vagal nerve therapy on weight loss remain controversial. This systematic review and meta-analysis assessed the effects of vagal nerve therapy on weight loss, body mass index (BMI), and obesity-related conditions. METHODS MEDLINE, EMBASE, and CINAHL databases were searched for studies up to April 2022 that reported on percentage excess weight loss (%EWL) or BMI at 12 months or remission of obesity-related conditions following vagal nerve therapy from January 2000 to April 2022. Weighted mean difference (WMD) was calculated, meta-analysis was performed using random-effects models, and between-study heterogeneity was assessed. RESULTS Fifteen studies, of which nine were randomised controlled trials, of 1,447 patients were included. Vagal nerve therapy led to some improvement in %EWL (WMD 17.19%; 95% confidence interval [CI]: 10.94-23.44; p < 0.001) and BMI (WMD -2.24 kg/m2; 95% CI: -4.07 to -0.42; p = 0.016). There was a general improvement found in HbA1c following vagal nerve therapy when compared to no treatment given. No major complications were reported. CONCLUSIONS Vagal nerve therapy can safely result in a mild-to-moderate improvement in weight loss. However, further clinical trials are required to confirm these results and investigate the possibility of the long-term benefit of vagal nerve therapy as a dual therapy combined with standard surgical bariatric interventions.

Abstract
In addition to age-related weight gain, menopause adds additional challenges for women with the occurrence of significant metabolic alterations and central and visceral fat redistribution. The changes in body composition then influence risks of cardiovascular disease, metabolic disruption, cancer, fracture, lung disease, sexual dysfunction, mental health disorders and dementia. They may also heighten the severity of vasomotor symptoms. Treatment of these changes requires a flexible long-term strategy. This narrative review explores the pathogenesis of the metabolic changes at menopause and effective management options.

Effect of Intraoperative Infusion of Esketamine on Quality of Postoperative Recovery in Patients Undergoing Laparoscopic Bariatric Surgery: A Randomized Controlled Trial. Pain Ther 2023; 12:979-992. [PMID: 37171754 PMCID: PMC10289955 DOI: 10.1007/s40122-023-00519-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/01/2023] [Accepted: 04/18/2023] [Indexed: 05/13/2023] Open
Abstract
INTRODUCTION This study aims to evaluate the efficacy of esketamine on postoperative recovery quality after laparoscopic bariatric surgery. METHODS Patients (n = 74) scheduled for laparoscopic bariatric surgery were randomly divided into two groups: the esketamine group (group E: 0.5 mg/kg/h infusion, i.e., 0.2 mL/kg/h) or the control group (group C: 0.2 mL/kg/h normal saline infusion). The infusions were stopped 20 min before the end of the procedure. The primary outcome was the Quality of Recovery-40 (QoR-40) score on postoperative day 1 (POD 1). The secondary outcomes included QoR-40 scores on PODs 2 and 7, Numeric Rating Scale (NRS) on PODs 1, 2, and 7, time to extubation, additional postoperative analgesic use, length of hospital stay, and time to first exhaust. Additonally, the safety indices were also recorded, including hemodynamic profile, perioperative anesthesia index (Ai), utilization of vasoactive drugs or urapidil, and side effects. RESULTS All in all, 70 of the 74 patients completed the study, 35 in each group. The difference of QoR-40 scores on POD 1 was both statistically and clinically significant [difference 7.21, 95% confidence interval (CI) 5.17, 9.25, p < 0.001]. The difference of QoR-40 on POD 2 was statistically significant but clinically insignificant (difference 4.81, 95% CI 2.69, 6.92, p < 0.001). The difference of NRS scores on POD 1 was statistically significant (difference -1.23, 95% CI -2.36, -0.10, p = 0.033). Compared with group C, group E had a lower utilization rate of phenylephrine and higher Ai values (p < 0.05). There was no statistical difference between the two groups on other measures. CONCLUSION Continuous ketamine infusion seems to be safe and well tolerated in laparoscopic bariatric surgery. It improved the quality of postoperative recovery and reduced pain on POD 1. In spite of the increased Ai value during the surgery, it also provided better hemodynamics with less usage of phenylephrine.

Abstract
Malnutrition is an international healthcare concern associated with poor patient outcomes, increased length of stay, and healthcare costs. Although malnutrition includes both under and overnutrition, there is a large body of evidence that describes the impacts of undernutrition with limited data on overnutrition in hospitalized patients. Obesity itself is a modifiable risk factor associated with hospital-associated complications. However, there is limited reporting of the prevalence of obesity in hospitals. This one-day cross-sectional study (n = 513) captures the prevalence of both under and overnutrition in a hospitalized population and explores dietetic care provided compared to the Nutrition Care Process Model for hospitalized patients who have obesity. The main findings were: (1) the largest proportion of patients were in the overweight and obese classifications (57.3%, n = 294/513); 5.3% of these patients had severe obesity (class III); (2) patients who were overweight and obese had lower malnutrition risk profiles as well as the prevalence of malnutrition; (3) 24.1% of patients who had obesity (n = 34/141) were receiving dietetic intervention; (4) 70.6% (n = 24/34) did not have a nutrition diagnosis that followed the Nutrition Care Process Model. Study results provide valuable clinical insight into the prevalence of overnutrition and opportunities to improve nutrition care for this vulnerable patient group.

Abstract
OBJECTIVE This paper reports the study design, participant characteristics, and recruitment results of By-Band-Sleeve, which investigated the clinical and cost-effectiveness of gastric bypass, gastric banding, and sleeve gastrectomy in adults with severe obesity in the UK. METHODS A pragmatic open adaptive noninferiority trial with 3-year follow-up was conducted. Participants were randomly assigned to bypass or band initially and to sleeve after the adaptation. Co-primary end points are weight loss and health-related quality of life assessed using the EQ-5D utility index. RESULTS Between December 2012 and August 2015, the study recruited into two groups and, after the adaptation, into three groups until September 2019. The study screened 6960 patients; 4732 (68%) were eligible and 1351 (29%) were randomized; 5 subsequently withdrew consent to use data, leaving 462, 464, and 420 assigned to bypass, band, and sleeve, respectively. Baseline data showed high levels of obesity (mean BMI = 46.4 kg/m2; SD: 6.9) and comorbidities (e.g., 31% diabetes), low scores for health-related quality of life, and high levels of anxiety and depression (e.g., 25% abnormal scores). Nutritional parameters were poor, and the average equivalized household income was low (£16,667). CONCLUSIONS By-Band-Sleeve fully recruited. Participant characteristics are consistent with contemporary patients having bariatric surgery, and therefore the results will be generalizable.

Abstract
BACKGROUND Bariatric surgery is the most effective treatment for sustained weight reduction and obesity-related comorbidities. The development of gallstones as a result of rapid weight loss is a well-known consequence of bariatric procedures. It remains unclear, if there is an increased risk of these gallstones becoming symptomatic. METHODS A retrospective analysis of 505 consecutive patients submitted to either Roux-en-Y Gastric Bypass or Sleeve Gastrectomy between January and December 2019 was performed. The aim of our study was to determine the incidence of symptomatic cholelithiasis in asymptomatic patients with their gallbladder in situ after bariatric surgery and to identify potential risk factors for its development. RESULTS Of the 505 patients included, 79 (15.6%) underwent either previous cholecystectomy. (n = 67, 84.8%) or concomitant cholecystectomy during bariatric surgery (n = 12, 15.2%). Among the remaining 426 (84.4%) patients, only 8 (1.9%) became symptomatic during the 12-month follow-up period. When compared with patients who remained asymptomatic, they had a higher median preoperative BMI (47.0 vs. 42.8, p = 0.046) and prevalence of cholelithiasis on preoperative ultrasound (62.5% vs. 10.7%, p = 0.001). Multivariate analysis revealed preoperative BMI and cholelithiasis on preoperative ultrasound as independent risk factors for symptomatic biliary disease (OR 1.187, 95%CI 1.025-1.376, p = 0.022 and OR 10.720, 95%CI 1.613-71.246, p = 0.014, respectively). CONCLUSION Considering a low incidence of symptomatic gallstones after bariatric surgery, concomitant cholecystectomy should only be performed in symptomatic patients undergoing bariatric surgery. Preoperative factors, such as a higher BMI and positive ultrasound for cholelithiasis, may be related to the development of symptomatic gallstones.

Apps were identified using search terms in the Android and Apple app stores. 52 apps were included. 42 (80.7%) apps main target users were patients. More than half, 27 (52%), targeted US based users. 29 (56%) had payment-restricted content. 42 (81%) had MAPI and the mean Silberg score was 5.2. Compared to previous studies the quality of BMS apps is improving with more MAPI and useful functionality. Wider use of mHealth apps for patient centred follow-up, management and care are yet to be widely implemented and explored.

Very Low-Calorie Ketogenic Diet (VLCKD) as Pre-Operative First-Line Dietary Therapy in Patients with Obesity Who Are Candidates for Bariatric Surgery. Nutrients 2023; 15:nu15081907. [PMID: 37111126 PMCID: PMC10142118 DOI: 10.3390/nu15081907] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2023] [Revised: 03/24/2023] [Accepted: 04/13/2023] [Indexed: 04/29/2023] Open
Abstract
Bariatric surgery is currently the most effective method for achieving long-term weight loss and reducing the risk of comorbidities and mortality in individuals with severe obesity. The pre-operative diet is an important factor in determining patients' suitability for surgery, as well as their post-operative outcomes and success in achieving weight loss. Therefore, the nutritional management of bariatric patients requires specialized expertise. Very low-calorie diets and intragastric balloon placement have already been studied and shown to be effective in promoting pre-operative weight loss. In addition, the very low-calorie ketogenic diet has a well-established role in the treatment of obesity and type 2 diabetes mellitus, but its potential role as a pre-operative dietary treatment prior to bariatric surgery has received less attention. Thus, this article will provide a brief overview of the current evidence on the very low-calorie ketogenic diet as a pre-operative dietary treatment in patients with obesity who are candidates for bariatric surgery.

Abstract
BACKGROUND In comparison to conservative therapy, bariatric surgery has shown many reasonable results. The current study investigates whether Omega-loop-gastric-bypass (OAGB) or Roux-en-Y gastric-bypass (RYGB) improves weight loss, comorbidities, and perioperative complications. METHODS The study included 28,683 patients after RYGB and OAGB. Outcome criteria were perioperative morbidity, perioperative complications, and remission of comorbidities after one year of follow-up. RESULTS Of them 14,253 patients had completed a one-year follow-up (13,483 patients by RYGB and 770 by OAGB). BMI reduction was a significant difference in favor of OAGB (17.5±5.6 kg/m2 for OAGB vs. 15.2±5.0 for RYGB; P<0.001). The %EWL was not significantly different between the two groups (P=0.073). There was also no significant difference in perioperative complications between the two groups (overall P>5%). Significant differences in favor of OAGB were observed in remission of insulin-dependent diabetes mellitus (IDDM) (P<0.001), and sleep apnea (P=0.002). Remission of reflux was more observed in RYGB than OAGB (P<0.001). Operating time was significantly higher in RYGB than OAGB (P<0.001). CONCLUSIONS Compared with RYGB, OAGB showed significant advantages in many respects. In particular, remission of comorbidities was significantly better after OAGB than in patients after RYGB during the one-year follow-up period. Nevertheless, many other factors such as medical history, long-term expected goals of bariatric surgery, and preexisting comorbidities should be taken into account when determining indications between the two procedures. Further studies with longer follow-up periods should be conducted to determine the efficacy of the two methods more accurately.

Abstract
BACKGROUND Prior literature has demonstrated that bariatric surgery is a safe approach for patients with morbid obesity. However, the relationship between body mass index (BMI) and risk of mortality in these patients has not been fully elucidated. Primary objective of this study was to evaluate the relationship between BMI and risk of mortality using data obtained from a national database, with a special focus on patients with BMI ≥ 70.0 kg/m2. METHODS A retrospective cohort study of patients with morbid obesity (BMI ≥ 40 kg/m2) undergoing first-time bariatric surgery between 2015 and 2018 was performed using data from the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program. Primary outcome was intra-operative death or death within 30 days post-operatively. Patients were categorized into quartiles according to BMI. Multivariable analysis was performed to evaluate the association of BMI with risk of mortality. Relative risk (RR) and 95% confidence interval (CI) are provided as measures of strength of association and precision, respectively. RESULTS A total of 463, 436 patients were included with a 30-day mortality rate of 0.11%. Mean BMI (SD) was 48.2 (7.3) kg/m2; 1.5% of patients had BMI ≥ 70.0 kg/m2. On multivariable analysis, highest quartile patients had a significantly higher risk of mortality than lowest quartile patients. For patients with BMI ≥ 70.0 kg/m2, the risk of mortality was more pronounced with an eightfold increase compared to the lowest quartile. In patients with BMI ≥ 70.0 kg/m2, although sleeve gastrectomy (SG) was the most common procedure, the risk of mortality was significantly higher in patients undergoing Roux-en-Y gastric bypass (RYGB). CONCLUSIONS BMI is associated with increased risk of 30-day mortality. The effect of BMI is more pronounced in patients with BMI ≥ 70.0 kg/m2. In these patients, RYGB is associated with increased risk of mortality compared to SG.

Abstract
Background: Laparoscopic sleeve gastrectomy (LSG) is the most common primary bariatric operation performed in the United States. Its relative technical ease, combined with a decreased risk for anatomic and malabsorptive complications make LSG an attractive option compared to laparoscopic gastric bypass (LGB) for many patients and surgeons. However, emerging evidence for progressive gastroesophageal reflux disease (GERD) after LSG, and the inferior weight loss in many studies, suggests that the enthusiasm for LSG requires reassessment. We hypothesized that patient satisfaction and quality of life (QoL) may be lower after LSG compared to LGB because of these differences. Methods: We distributed a survey querying weight-loss outcomes, complications, foregut symptoms, QoL, and overall satisfaction to patients who underwent bariatric operations at our institution between 2000 and 2020 and who had electronic mail contact information available. Mean follow-up was 2.75 ± 2.41 years for LGB patients and 3.37 ± 2.18 (P = .021) years for LSG patients. We compared these groups for weight-loss outcomes, changes in foregut symptoms, gastrointestinal QoL, postbariatric QoL, and overall satisfaction using appropriate statistical tests. Results: Among 323 respondents, 126 underwent LGB and 197 underwent LSG. LGB patients had larger body mass index (BMI) reduction than LSG patients (-17.16 ± 9.07 kg/m2 versus -14.87 ± 7.4 kg/m2, P = .023). LGB patients reported less reflux (P = .003), with decreased heartburn (P < .0001) and regurgitation (P = .0027). However, a greater proportion of LGB patients reported at least one complication (P = .025). Despite this, more LGB patients reported satisfaction (92.86%) than LSG patients (73.6%). Conclusion: LGB patients are significantly more likely to be satisfied than LSG patients. Factors contributing to the higher level of satisfaction include less GERD and better BMI decrease.

Abstract
AIM Randomized trials reporting 5-year outcomes have shown bariatric surgery to induce diabetes remission and improve cardiovascular risk. However, the longer-term effects of surgery are uncertain, with only one randomized trial reporting 10-year diabetes outcomes in people with obesity. We aimed to compare 10-year diabetes outcomes of people who are overweight but not obese, randomly assigned to receive either multidisciplinary diabetes care, or multidisciplinary diabetes care combined with gastric band (GB) surgery. METHODS Between 2009 and 2011, 51 adults were randomized. After 5 years, they were discharged to receive community care and reassessed after 10 years. The primary outcome was diabetes remission, defined as glycated haemoglobin (HbA1c) <6.5% (48 mmol/mol) without glucose-lowering medication. RESULTS Forty-one participants (20 medical and 21 GB) completed the 10-year assessment. The median (Q1, Q3) weight loss in the GB group was 9.8 (6.7, 16.3)% at 10 years compared with 5.6 (3.4, 7.6)% in the medical group (median difference 4.2%; p = .008). Diabetes remission occurred in five GB participants and no medical participants (relative risk 0.76, 95% CI: 0.55-0.93, p = .048). GB participants used fewer glucose-lowering medications at 10 years but HbA1c, fasting glucose, calculated cardiovascular risk, quality-of-life and incident diabetes complications did not differ significantly between the groups. CONCLUSION When compared with medical care, GB surgery achieved greater weight loss and modestly increased the likelihood of diabetes remission. However, it did not improve HbA1c, cardiovascular risk or quality of life.

Abstract
Obesity is a complex worldwide disease, characterized by an abnormal or excessive fat accumulation. The onset of this pathology is generally linked to a complex network of interactions among genetic and environmental factors, aging, lifestyle, and diets. During adipogenesis, several regulatory mechanisms and transcription factors are involved. As fat cells grow, adipose tissue becomes increasingly large and dysfunctional, losing its endocrine function, secreting pro-inflammatory cytokines, and recruiting infiltrating macrophages. This long-term low-grade systemic inflammation results in insulin resistance in peripheral tissues. In this review we describe the main mechanisms involved in adipogenesis, from a physiological condition to obesity. Current therapeutic strategies for the management of obesity and the related metabolic syndrome are also reported.

Abstract
PURPOSE Obesity is a growing global issue with evidence linking it to an increase in loss of disease-free years, reduced quality of life, increased mortality, and additional economic burden. This study sought to establish the cost-effectiveness of gastric bypass and sleeve gastrectomy, compared to conventional therapy in patients with obesity, from a Tunisian healthcare payor perspective. PATIENTS AND METHODS A Markov model compared lifetime costs and outcomes of bariatric surgery with conventional treatment among patients with body mass index (BMI) ≥ 40 kg/m2, BMI ≥ 35 kg/m2 with obesity-related co-morbidities (Group 1), or BMI ≥ 35 kg/m2 with type 2 diabetes mellitus (T2DM) (Group 2). Inputs were sourced from the Tunisian Health Examination Survey, local clinician data and literature sources. Health states were associated with different cost and utility decrements. Changes in body mass index, systolic blood pressure, lipid ratio and diabetes remission rates were modelled on a yearly basis. The incremental cost-effectiveness ratio (ICER), quality-adjusted life years (QALYs) and net monetary benefit (NMB) were key outcomes. Sensitivity and scenario analyses were performed to test the model's robustness. RESULTS The model showed that the benefits of bariatric surgery were favorable compared to conventional treatment, with an ICER of 1844 TND/QALY in Group 1 patients and 2413 TND/QALY in Group 2 patients. Bariatric surgery resulted in a QALY gain of 3.26 per patient in Group 1 and a gain of 1.77 per patient in Group 2. At a willingness to pay threshold of 31,379 TND/QALY, the incremental NMB was 96,251 TND and 51,123 TND for Group 1 and Group 2, respectively. CONCLUSION From the Tunisian healthcare payor perspective, bariatric surgery is cost-effective for patients with obesity and those with T2DM and obesity-related comorbidities. These findings may have impact on future decision-making on funding and reimbursement of bariatric surgery in Tunisia.

Abstract
In this review, we collated evidence relating to taste change and zinc deficiency in relation to bariatric surgery (BS) and effects of zinc replacement on taste perception and speculate on the possible role of zinc deficiency to induce taste change after BS. A literature search was conducted (33 studies, N = 3264). We showed that taste change and zinc deficiency are frequent complications after BS, which both typically occurred at 6 months post-surgery. Our analysis did not support a causal link between the two, but similar onset of incidences indirectly indicates a link. Supplementation with 45-50 mg of zinc sulphate, higher than current recommendation, was effective in improving taste. Further studies are required to establish the causal link between the two in the context of BS.

Abstract
Morbid obesity is considered a civilization disease of the 21st century. Not only does obesity increase mortality, but it is also the most important cause of the shortening life expectancy in the modern world. Obesity is associated with many metabolic abnormalities: dyslipidemia, hyperglycemia, cardiovascular diseases, and others. An increasing number of patients diagnosed with chronic kidney disease (CKD) are obese. Numerous additional disorders associated with impaired kidney function make it difficult to conduct slimming therapy and may also be associated with a greater number of complications than in people with normal kidney function. Currently available treatments for obesity include lifestyle modification, pharmacotherapy, and bariatric surgery (BS). There are no precise recommendations on how to reduce excess body weight in patients with CKD treated conservatively, undergoing chronic dialysis, or after kidney transplantation. The aim of this study was to analyze studies on the bariatric treatment of obesity in this group of people, as well as to compare the recommendations typical for bariatrics and CKD.

OBJECTIVES To explore the relationship between the blood group of patients and their response to bariatric surgery and to identify predictors of better outcomes. METHODS 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. RESULTS 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). CONCLUSIONS 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.

[PMID: 36431314 PMCID: PMC9693218 DOI: 10.3390/jcm11226837] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2022] [Revised: 11/15/2022] [Accepted: 11/17/2022] [Indexed: 11/22/2022] Open
Abstract
Background: Bariatric surgery (BS) patients may experience the progression of periodontitis during recovery. We aimed to determine whether non-surgical periodontal therapy before BS improves the periodontal and systemic health parameters after the surgery. Methods: BS candidates with periodontitis were randomized into the test (TG) and control group (CG). One month before BS (pre-BS), patients in the TG (n = 15) received non-surgical periodontal therapy, while patients in the CG (n = 15) received only mechanical plaque removal. Patients were re-examined 3 and 6 months after BS. Differences between the TG and CG in clinical periodontal parameters, systemic health-related serum biomarkers, parameters of obesity, and prevalence of obesity-related diseases were evaluated. Results: From the 30 included patients, 26 were re-examined at 3 months and 20 patients at 6 months. Periodontal parameters bleeding on probing (p = 0.015), periodontal pocket dept (PPD, p = 0.0015), % PPD > 4 mm (p < 0.001), and full-mouth plaque levels (p = 0.002) were lower in the TG than in the CG at 6 months after BS. There is a general improvement in systemic health after BS without significant differences (p > 0.05) between the TG and CG at the 6-month follow-up. The TG shows a tendency for improvement in metabolic syndrome components at the 6-month follow-up compared to pre-BS (p < 0.05). Conclusions: Non-surgical periodontal therapy in periodontitis patients before the BS may improve periodontal health 3 and 6 months after the surgery. The possible benefits of periodontal therapy on the overall health of BS patients should be further explored.

Abstract
INTRODUCTION Obesity is a chronic disease with a complex interplay of multiple factors such as genetic, metabolic, behavioral, and environmental factors. The management of obesity includes; lifestyle modification, psychological therapy, pharmacological therapy, and bariatric surgery. To date, bariatric surgery is the most effective treatment for obesity by offering a long-term reduction in weight, remission of obesity-related complications, and improving quality of life. However, bariatric surgery is not equally effective in all patients. Thus, if we can predict who would benefit most, it will improve the risk versus benefit ratio of having surgery. AREAS COVERED In this narrative review, we explore the question on who will benefit the most from bariatric surgery by examining the recent evidence in the literature. In addition, we investigate the predisposing predictors of bariatric surgery response. Finally, we offer the best strategies in the clinic to explain the potential benefits of bariatric surgery to patients. EXPERT OPINION Bariatric surgery is an effective obesity management approach. Despite its efficacy, considerable variation of individual response exists. Thus, it is important to recognize patients that will benefit most, but at present very few predictors are available which can be clinically useful.

Abstract
Bariatric surgery (BS) is the most effective treatment in reducing weight and the burden of comorbidities in patients with severe obesity. Despite the overall low mortality rate, intra- and post-operative complications remains quite common. Weight loss before BS reduces surgical risk, but studies are inconclusive regarding which is the best approach to apply. In this review, we summarize the current evidence on the effect of a ketogenic diet (KD) before BS. All studies agree that KD leads to considerable weight loss and important improvements in terms of surgical risk, but populations, interventions and outcomes are very heterogeneous. KD appears to be a safe and effective approach to induce weight loss before BS. However, randomized controlled trials with better-defined dietary protocols and homogeneous outcomes are necessary in order to draw firm conclusions.

Abstract
BACKGROUND Laparoscopic sleeve gastrectomy (LSG) is a commonly performed bariatric surgery. Gastric stenosis and leaks are 2 major complications associated with LSG and revision surgery might be needed. Herein, we report our experience of intraoperative endoscopy (IOE) to evaluate stenosis and leaks during LSG. METHODS LSG was performed by three surgeons. Patients who underwent LSG and IOE between January 2016 and March 2020 were enrolled and assigned to two groups: group 1 (1st-30th LSG case for each surgeon) and group 2 (> 30th LSG for each surgeon). Patients' anthropometric and biochemical data pre- and post-LSG, as well as IOE findings and follow-up esophagogastroduodenoscopy records were reviewed. RESULTS In total, 352 patients were enrolled including 90 patients in group 1 and 262 patients in group 2. Three out of 352 patients (0.9%) were found to have stenosis by IOE, which was related to tightly gastropexy stitch or reinforcement stitch, all of which were in group 1. Stenosis was resolved after removal of the stitch during LSG. The incidence of gastric stenosis detected by IOE was 3.3% (3/90) and 0% (0/262) in group 1 and group 2, respectively (P = 0.003). No leakage was found in this study and no patient developed clinical or endoscopic stenosis after LSG. CONCLUSIONS The existing evidence showed that IOE can help detect gastric stenosis during LSG, especially for novice surgeons, and the stenosis could be resolved during operation.

Transition from a circular to a linear stapling protocol in laparoscopic Roux-en-Y gastric bypass surgery and its impact on quality of life: a 5-year outcome study. Langenbecks Arch Surg 2022; 407:3341-3348. [PMID: 35947218 DOI: 10.1007/s00423-022-02635-0] [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: 03/31/2022] [Accepted: 07/29/2022] [Indexed: 10/15/2022]
Abstract
PURPOSE Surgical technique in bariatric surgery has been refined over the past decades. This study analysed the effect of changing the stapling protocol on the quality of life (QoL) at a midterm follow-up. METHODS The retrospective cohort study included patients undergoing Roux-en-Y gastric bypass between June 2012 and March 2016. Patients were stratified into the circular stapling protocol (CSP, n = 117) or the linear stapling protocol (LSP, n = 118). QoL was quantified by the Moorehead score at 12, 24 and 60 months. Multivariate testing was used to identify confounders. RESULTS The age was 42.8 ± 11.5 years and the body mass index (BMI) was 43.8 ± 6.2 kg/m2, with no baseline intergroup differences. Overall baseline Moorehead score was 0.42 ± 1.1 and improved in both groups after 12 months (1.97 ± 0.74, p < 0.001), 24 months (1.86 ± 0.79, p < 0.001) and 60 months (1.71 ± 0.9, p < 0.001). LSP was associated with improved Moorehead score after 60 months (odds ratio [OR] 1.251, 95% confidence interval [CI] 1.06-1.48, p = 0.010). Overall, a drop of mean BMI occurred and this effect lasted throughout the observation period (- 12.48 kg/m2, p < 0.001). More profound BMI reduction was further positively associated with Moorehead scores after 24 and after 60 months (OR 0.97, p = 0.028; OR 0.96, p = 0.007). Complications, rehospitalisations and reoperations were more frequent in the CSP group (50% vs 23.7%, p < 0.001; 39.7% vs 22.9%, p = 0.009; 37.1% vs 18.6%, p = 0.003). CONCLUSION The CSP and LSP achieve a long-lasting increase in QoL, although the LSP is associated with fewer complications, persistent weight loss and improved Moorehead score. Therefore, the LSP might be considered the favourable protocol in Roux-en-Y gastric bypass.

Is development in bariatric surgery in Germany compatible with international standards? A review of 16 years of data. Updates Surg 2022; 74:1571-1579.

Abstract
Bariatric surgery has expanded tremendously internationally over the past decade. In recent years, bariatric surgery has experienced a significant growth in Germany. However, the question arises as to whether this development is in line with international developments or whether there is still room for improvement that could be challenged. 63,990 primary bariatric procedures recorded in the German Bariatric Surgery Registry (GBSR) were analyzed from 2005 to April 2021. The distribution of procedures according to different variants was analyzed and presented. In the last 16 years, 17 different procedures have been performed. The most common surgical procedure was sleeve gastrectomy (SG), followed by Roux-Y gastric bypass (RYGB) (42%). Adjustable gastric banding (AGB) has declined over time, from 23.5% in the first 5 years to 0.2% in recent years. In comparison, omega-loop gastric bypass has increased over the past 5 years (from 0.4% in the first 5 years to 5.9% in the last 5 years). Laparoscopic procedures have accounted for 96.4% of all bariatric surgeries in recent years. The frequency of some procedures has decreased and some bariatric procedures have lost significance. Overall, bariatric surgery in Germany has developed positively compared to the international trend. Nevertheless, there is one area that needs to be optimized: the development of robotic bariatric surgery, which crawls behind in Germany compared to other countries. To establish the technology in bariatric surgery in a timely manner, a balance must be found between cost neutrality and patient-oriented applications.

Acceptability and feasibility of the TELEhealth BARIatric behavioural intervention to increase physical ACTIVity (TELE-BariACTIV): A single-case experimental study protocol (Preprint). JMIR Res Protoc 2022; 11:e39633.

Abstract
Background Regular physical activity (PA) is recommended to optimize weight and health outcomes in patients who have undergone metabolic and bariatric surgery (MBS). However, >70% of patients have low PA levels before MBS that persist after MBS. Although behavioral interventions delivered face-to-face have shown promise for increasing PA among patients who have undergone MBS, many may experience barriers, preventing enrollment into and adherence to such interventions. Delivering PA behavior change interventions via telehealth to patients who have undergone MBS may be an effective strategy to increase accessibility and reach, as well as adherence. Objective This paper reports the protocol for a study that aims to assess the feasibility and acceptability of the protocol or methods and the Telehealth Bariatric Behavioral Intervention (TELE-BariACTIV). The intervention is designed to increase moderate-to-vigorous intensity PA (MVPA) in patients awaiting bariatric surgery and is guided by a multitheory approach and a patient perspective. Another objective is to estimate the effect of the TELE-BariACTIV intervention on presurgical MVPA to determine the appropriate sample size for a multicenter trial. Methods This study is a multicenter trial using a repeated (ABAB’A) single-case experimental design. The A phases are observational phases without intervention (A1=pre-MBS phase; A2=length personalized according to the MBS date; A3=7 months post-MBS phase). The B phases are interventional phases with PA counseling (B1=6 weekly pre-MBS sessions; B2=3 monthly sessions starting 3 months after MBS). The target sample size is set to 12. Participants are inactive adults awaiting sleeve gastrectomy who have access to a computer with internet and an interface with a camera. The participants are randomly allocated to a 1- or 2-week baseline period (A1). Protocol and intervention feasibility and acceptability (primary outcomes) will be assessed by recording missing data, refusal, recruitment, retention, attendance, and attrition rates, as well as via web-based acceptability questionnaires and semistructured interviews. Data collected via accelerometry (7-14 days) on 8 occasions and via questionnaires on 10 occasions will be analyzed to estimate the effect of the intervention on MVPA. Generalization measures assessing the quality of life, anxiety and depressive symptoms, and theory-based constructs (ie, motivational regulations for PA, self-efficacy to overcome barriers to PA, basic psychological needs satisfaction and frustration, PA enjoyment, and social support for PA; secondary outcomes for a future large-scale trial) will be completed via web-based questionnaires on 6-10 occasions. The institutional review board provided ethics approval for the study in June 2021. Results Recruitment began in September 2021, and all the participants were enrolled (n=12). Data collection is expected to end in fall 2023, depending on the MBS date of the recruited participants. Conclusions The TELE-BariACTIV intervention has the potential for implementation across multiple settings owing to its collaborative construction that can be offered remotely.

Abstract
INTRODUCTION Advanced liver disease and portal hypertension (PH) are seen as a relative contraindication for bariatric and metabolic surgery. Several studies have shown significant improvement in liver function and liver histology after bariatric surgery. There are very few studies describing bariatric surgery in patients with PH. The purpose of this retrospective study is to evaluate the feasibility and results of laparoscopic sleeve gastrectomy (SG) in patients with PH. MATERIAL AND METHODS We present our experience of performing laparoscopic SG in 15 patients with evidence of PH. All the patients were Childs Pugh Criteria A. PH was confirmed by the presence of dilated esophageal varices on endoscopy. RESULTS The mean operative time was 77.33 ± 15.22 min and mean blood loss was 80.67 ± 37.12 ml. The mean length of stay was 2.73 ± 0.59 days. There were no intraoperative or immediate postoperative complications. None of the patients required blood transfusion in the postoperative period. The weight, BMI, Excess body weight loss% (EBWL%), Total weight loss (TWL) and TWL% at 1 year were 86.05 ± 14.40 kg, 31.16 kg/m2 ± 3.82, 63.84% ± 15.24, 31.49 ± 9.54 kg and 26.50 ± 5.42%, respectively. Diabetes and hypertension resolution at 1 year was 80% and 72.72%, respectively. All the patients were followed up for mean 3 ± 1.5 years. There were no immediate or long-term morbidity and mortality noted. CONCLUSION SG is a feasible and safe option for the treatment of obesity in carefully selected patients with PH with good weight loss and comorbidity resolution.

Abstract
Patients who undergo bariatric surgery (BS) have an increased risk of falls. Our aim was to determine if a multicomponent exercise intervention after BS improves balance. Eighty-four patients with obesity enrolled for BS were recruited and 1 month after BS randomly allocated to a control (CG; standard medical care) or exercise group (EG; exercise plus standard medical care) consisting of a supervised multicomponent training program (3d/week; 75 min/session; 5 months). Anthropometry, lower limb muscle strength (isokinetic dynamometer), vitamin D (ELISA) and balance in bipedal stance (force platform) were assessed pre-BS, 1 month and 6 months post-BS. One month post-BS, significant balance improvements were observed, namely in antero-posterior center of gravity (CoG) displacement and velocity, and medio-lateral and total CoG velocity. Between 1- and 6-months post-BS, improvements in balance were observed only in the EG, with a significant treatment effect on CoG displacement area and antero-posterior CoG displacement. No significant differences were observed between EG and CG over time in any of the anthropometric, muscle strength, and vitamin D variables assayed. In conclusion, a multicomponent exercise intervention program improves some balance parameters in patients with severe obesity following BS and therefore should be part of post-BS follow-up care as a potential strategy to reduce falls and associated injuries.

Comparative risk of anemia and related micronutrient deficiencies after Roux-en-Y gastric bypass and sleeve gastrectomy in patients with obesity: An updated meta-analysis of randomized controlled trials. Obes Rev 2022; 23:e13419. [PMID: 35048495 DOI: 10.1111/obr.13419] [Citation(s) in RCA: 13] [Impact Index Per Article: 6.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 12/21/2021] [Accepted: 12/22/2021] [Indexed: 12/12/2022]
Abstract
Although Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are the most prevalent bariatric surgical procedures, high-level evidence is scarce regarding the assessment of postoperative nutritional risk in RYGB versus SG. Therefore, we performed a systematic review and meta-analysis to compare the risk of anemia and related micronutrient deficiencies after RYGB and SG. We analyzed 10 randomized controlled trials that compared RYGB and SG with reported incidence of postoperative anemia and/or anemia-related micronutrient deficiencies (iron, vitamin B12 , or folate). There were no significant differences in the risk of postoperative anemia (moderate level of evidence), iron deficiency (high level of evidence), or folate deficiency (moderate level of evidence). Patients undergoing RYGB had a higher risk of postoperative vitamin B12 deficiency than those undergoing SG (relative risk, 1.86; 95% confidence interval, 1.15-3.02; p = 0.012; high level of evidence). Our findings imply that patients undergoing RYGB require more stringent vitamin B12 supplementation and surveillance than those undergoing SG. Additionally, our results may aid patients with high concern for anemia and related micronutrient deficiencies in making informed decisions regarding surgical methods based on nutritional risk.

Awareness and Attitude of Surgeons regarding Dental Erosion on Patients Who Underwent Bariatric Surgery. Int J Dent 2022; 2022:1812715. [PMID: 35237328 PMCID: PMC8885246 DOI: 10.1155/2022/1812715] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/18/2021] [Revised: 01/08/2022] [Accepted: 02/01/2022] [Indexed: 11/18/2022] Open
Abstract
Background The obesity epidemic is considered one of the main challenges for modern medicine. It has been proven that bariatric surgery is more effective than nonsurgical interventions to manage weight-related comorbidities. The general surgeon needs to understand how tooth erosion advances in gastroesophageal reflux in people who have had bariatric surgery. Dental erosion caused due to gastric reflux begins with the enamel, which is the tough, protective coating that covers our teeth. While it is tough, it is prone to an extremely acidic environment with a low pH, where it begins to soften and demineralize, gradually wearing away and exposing the more sensitive areas of the tooth. Because of the growing popularity of this subspecialty, general surgeons should develop a basic clinical and surgical understanding of these standard procedures and complications, regardless of their interest in obesity surgery. Aim This cross-sectional study aimed to assess the awareness and attitude of surgeons regarding dental erosion on patients who underwent bariatric surgery. Materials and Methods This cross-sectional study was conducted on general surgeons from different regions of Saudi Arabia who perform bariatric surgeries. Data collection was done by sending the questionnaire to the general surgeons by different means of social media (WhatsApp, e-mail, Facebook, etc.), and it was also distributed through the Saudi Arabia Society of Metabolic and Bariatric Surgery. Results A total of 25 general surgeons responded to the survey. Half of the respondents know what dental erosion is, 52%. Most of them, 72%, are not aware of the relationship between dental erosion and acid reflux or vomiting. They reported that 52% of patients complain of gastroesophageal reflux disorder. Conclusion The general surgeons had inadequate awareness and attitude regarding dental erosion on bariatric surgery patients. Our findings suggest that a lack of adequate awareness and a negative attitude among general surgeons are grounds for concern and that more should be done to avoid oral health complications.

Abstract
Of the women who gave birth in Australia in 2018, 47% had overweight or obesity, with obesity being associated with both maternal and fetal complications. Bariatric surgery improves fertility and some pregnancy‐related outcomes. Following bariatric surgery, pregnancy should be delayed by at least 12–18 months due to adverse pregnancy outcomes associated with rapid weight loss. Contraception should be prescribed after bariatric surgery, although the effectiveness of the oral contraceptive pill may be reduced due to malabsorption and contraceptive devices such as intrauterine devices should be considered as first line therapy. After bariatric surgery, women should undergo close monitoring for nutritional insufficiencies before, during and after pregnancy. Expert opinion recommends these women undergo dietary assessment and supplementation to prevent micronutrient deficiencies. Bariatric surgeons, bariatric medical practitioners, bariatric dieticians, the patient’s usual general practitioner, obstetricians, and maternity specialists should be involved to assist in the multidisciplinary management of these complex patients.

Abstract
Purpose We aimed to estimate the total cost of bariatric surgery in Denmark. Materials and Methods The study population included all Danish citizens ≥ 18 years who had received bariatric surgery, identified in the Danish National Patient Register in the period from 2002 to 2018. Patients who had received bariatric surgery were matched with three controls on gender, year of birth, and region of residence. A difference-in-difference approach was used to estimate the healthcare costs attributable to bariatric surgery from 3 years before to 5 years after surgery. Results Total healthcare costs for cases receiving bariatric surgery during the first 5 years following surgery amounted to EUR 32,899, and EUR 16,651 for their matched controls. Thereby, the difference in total healthcare costs (EUR 16,248) between persons receiving bariatric surgery and their matched controls was 2.2 times the DRG rate for the surgery itself (EUR 7387). Moreover, the results suggest that receiving bariatric surgery led to a total increase in gross earnings of EUR 5970 (5%) and a total reduction in receipt of transfer payments of EUR 4488 (12%) in the period up until 5 years after surgery. Conclusion The results showed a significant and persistent increase in healthcare costs for people with obesity receiving bariatric surgery during the first 5 years after surgery. We also found that bariatric surgery was associated with increased attachment to the labor market. Graphical abstract ![]()
