Bariatric surgery is established as a highly effective treatment for obesity and related metabolic complications. Although once seen as a last resort for patients with obesity, given the data demonstrating the profound weight loss, improvement in comorbidity and safety, perceptions have since shifted. There is evidence from 12 RCTs demonstrating its safety and efficacy in terms of weight loss which is sustained in the long term with a resultant improvement in co-morbidity. Clinicians are increasingly recognising the importance of timely intervention to maximise the effects of bariatric surgery, particularly in light of the low likelihood of being able to adequately manage patients with medication or lifestyle interventions alone. The inclusion of bariatric surgery in the standard treatment algorithm has been a step forward in the approach to treating patients with obesity. What remains challenging for clinicians is knowing which procedure is most beneficial to patients. There is no level one data demonstrating the superiority of one procedure over another. Head to head RCTs are ongoing which may shed light on this question; however, it is likely that there is no single procedure that will be demonstrated to be the gold standard. Herein we review the most commonly performed procedures along with the evidence available to support their effects with regards to weight loss and metabolic changes along with their limitations and recognised risks. The aim is to provide a general framework to allow clinicians to take advantage of the variety of operative approaches to tailor their treatment strategy to the individual patient.

Nutritional Studies

There are few long-term nutritional studies in subjects undergoing bariatric surgery that have assessed weight regain and nutritional deficiencies. In this study, we report data 8 years after surgery on weight loss, use of dietary supplements and deficit of micronutrients in a cohort of patients from five centres in central and northern Italy. The study group consisted of 52 subjects (age: 38.1 ± 10.6 y, 42 females): 16 patients had Roux-en-Y gastric bypass (RYGB), 25 patients had sleeve gastrectomy (SG) and 11 subjects had adjustable gastric banding (AGB). All three bariatric procedures led to sustained weight loss: the average percentage excess weight loss, defined as weight loss divided by excess weight based on ideal body weight, was 60.6% ± 32.3. Despite good adherence to prescribed supplements, 80.7% of subjects (72.7%, AGB; 76.7%, SG; 93.8 %, RYGB) reported at least one nutritional deficiency: iron (F 64.3% vs. M 30%), vitamin B12 (F 16.6% vs. M 10%), calcium (F 33.3% vs. M 0%) and vitamin D (F 38.1% vs. M 60%). Long-term nutritional deficiencies were greater than the general population among men for iron and among women for vitamin B12.

AbstractObesity is a growing worldwide epidemic with significant economic burden that carries with it impacts on every physiologic system including the cardiovascular system. Specifically, the risk of heart failure has been shown to increase dramatically in obese individuals. The purpose of this review is to provide background on the individual burdens of heart failure and obesity, followed by exploring proposed physiologic mechanisms that interconnect these conditions, and furthermore introduce treatment strategies for weight loss focusing on bariatric surgery. Review of the existing literature on patients with obesity and heart failure who have undergone bariatric surgery is presented, compared, and contrasted.

Obesity is an epidemic in our society, and rates continue to rise, along with comorbid conditions associated with obesity. Unfortunately, obesity remains refractory to behavioral and drug therapy but has shown response to bariatric surgery. Not only can long-term weight loss be achieved, but a majority of patients have also shown improvement of the comorbid conditions associated with obesity. A rise in the use of surgical therapy for management of obesity presents a challenge with an increased number of patients with problems after bariatric surgery. It is important to be familiar with symptoms following bariatric surgery, such as nausea/vomiting, abdominal pain, dysphagia, and upper gastrointestinal bleeding and to utilize appropriate available tests for upper gastrointestinal tract pathology in the postoperative period.

In the general population, bariatric surgery facilitates sustained weight loss and remission of comorbidities (e.g., CVD). The effectiveness among Medicaid beneficiaries, a population with a disproportionately high burden of obesity, remains unclear. We sought to determine if patterns of weight change following bariatric surgery differed in patients with Medicaid compared to commercial insurance. Data were obtained from the Longitudinal Assessment of Bariatric Surgery, an observational cohort study of adults undergoing bariatric surgery (2006-2009) at one of 6 geographically diverse centers. We used group-based trajectory models (PROC TRAJ, SAS) to identify discrete groups of individuals with similar weight trajectories over 5-years; we considered cubic trajectory models with between 1 and 6 groups. We selected the 6-group model based on Bayesian Information Criteria, visual fit and statistical significance of parameter estimates. We tested demographic predictors against trajectory group membership; Medicaid (n=174) vs. Commercial (n=991) was our primary predictor of interest. Medicaid participants had higher mean weight at baseline compared to the commercially insured (307.9 vs. 291.2 lbs), but lost a similar amount of weight over time (74.8 vs 85.0 lbs). All groups experienced the most weight loss in year 1 (Figure). Group 6 was the heaviest at baseline and began to regain weight after year 1; groups 1-5 continued to lose weight through year 2. Group’s 1 & 2 weight remained stable over 5 years while groups 3-6 began to slowly regain weight. Medicaid beneficiaries were more likely to be in group 4 (OR 3.2, 95% CI: 1.2, 8.6), group 5 (OR 5.7, 95% CI: 2.0, 16.1) and group 6 (OR 7.9, 95% CI: 2.5, 25.1) compared to group 1. Medicaid beneficiaries experience substantial long term weight loss. However, they had higher baseline weight and tended to be in groups with less long-term weight loss compared to the commercially insured. Focusing on tailored interventions to specific patient groups could help maintain weight loss.

<b><i>Objectives:</i></b> The growing prevalence of obesity rates worldwide is associated with an upsurge in its comorbidities, particularly type 2 diabetes mellitus (T2DM). Bariatric surgery is a proven treatment modality for producing sustained weight loss and resolution of associated T2DM providing marked improvement in quality of life with rapid recovery. This study aims to investigate the effects of laparoscopic sleeve gastrectomy (LSG), Roux-en-Y gastric bypass (RYGB), and mini-gastric bypass (MGB) on obese patients suffering from T2DM in the Indian population and their long-term association with regard to diabetes remission, resolution of comorbidities, and percentage EWL. <b><i>Methods:</i></b> Retrospective data of obese patients with T2DM (preoperative BMI 45.37 ± 8.1) who underwent bariatric surgery (RYGB, LSG, and MGB) were analyzed in this study over a period of 9 years. The mean follow-up period was 2.2 years. Following surgery, the clinical outcome on BMI, resolution of percentage weight loss, and T2DM were studied. The predictive factors of diabetic remission after surgery were determined. Student’s <i>t</i> test and ANOVA and McNemar’s test were applied. <b><i>Results:</i></b> Out of a total of 274 patients, complete remission of T2DM was achieved in 52.9% (<i>n</i> = 145) with mean fasting blood glucose and glycated hemoglobin values being 6.1 ± 0.769 (<i>p</i> = 0.00) at 1 year after surgery. The independent predictive factors of remission were age, gender, BMI, preoperative comorbidities, and % EWL. Gender had no correlation with the chance of achieving disease remission. <b><i>Conclusion:</i></b> Based on our results, bariatric surgery proves to be a successful treatment option resulting in sustained weight loss in obese patients suffering from T2DM. It is found to be beneficial for the long-term resolution of T2DM and improving comorbidities such as hypertension and dyslipidemia. The outcome of the different surgical methods is found to be similar for all patients irrespective of the independent predictors of complete remission.

Abstract Background Bariatric surgery, such as Roux-en-Y gastric bypass [RYGB] has been shown to be an effective intervention for weight management in select patients. After surgery, different patients respond differently even to the same surgery and have differing weight-change trajectories . The present analysis explores how improving a patient’s post-surgical weight change could impact co‑morbidity prevalence, treatment and associated costs in the Canadian setting. Methods Published data were used to derive statistical models to predict weight loss and co‑morbidity evolution after RYGB. Burden in the form of patient-years of co-morbidity treatment and associated costs was estimated for a 100-patient cohort on one of 6 weight trajectories, and for real-world simulations of mixed patient cohorts where patients experience multiple weight loss outcomes over a 10-year time horizon after RYGB surgery. Costs (2018 Canadian dollars) were considered from the Canadian public payer perspective for diabetes, hypertension and dyslipidaemia. Robustness of results was assessed using probabilistic sensitivity analyses using the R language. Results Models fitted to patient data for total weight loss and co-morbidity evolution (resolution and new onset) demonstrated good fitting. Improvement of 100 patients from the worst to the best weight loss trajectory was associated with a 50% reduction in 10-year co-morbidity treatment costs, decreasing to a 27% reduction for an intermediate improvement. Results applied to mixed trajectory cohorts revealed that broad improvements by one trajectory group for all patients were associated with 602, 1,710 and 966 patient-years of treatment of type 2 diabetes, hypertension and dyslipidaemia respectively in Ontario, the province of highest RYGB volume, corresponding to a cost difference of $3.9 million. Conclusions Post-surgical weight trajectory, even for patients receiving the same surgery, can have a considerable impact on subsequent co-morbidity burden. Given the potential for alleviated burden associated with improving patient trajectory after RYGB, health care systems may wish to consider investments based on local needs and available resources to ensure that more patients achieve a good long-term weight trajectory.
