Abstract
Type 2 diabetes mellitus (T2DM) in youth is invading the communities because, if not controlled on time, the long-term complications include cardiovascular diseases, nephropathy, neuropathy, and retinopathy that cause immense mortality and morbidity. Lifestyle changes and antidiabetic drugs are considered the foundation of T2DM therapy. However, these adjustments usually do not effectively produce long-term glycemic regulation, especially in patients with obesity of the third and fourth degrees. Bariatric surgery has also been identified as an efficacious intervention for obesity and obesity-related complications such as T2DM. Roux-en-Y gastric bypass (RYGB) has proven to be one of the most effective procedures in causing considerable weight loss and enhancing glycemic changes. This review provides a comprehensive analysis of RYGB in patients with young-onset T2DM regarding the improvement of glycemic control, weight loss, and diabetes comorbidities. RYGB has been established as a practice in the treatment of T2DM and severe obesity. This narrative review underscores the various effects of RYGB, such as enhanced glycemic control, considerable and long-term weight loss, and reduced cardiovascular disease risks. However, the review also points toward the directions and the adverse effects of RYGB regarding metabolic and skeletal health. There are risks of nutritional deficiencies, increased fracture rates, and even relapse to diabetes, which make patient selection, proper pre and postoperative investigation, and critical monitoring.

Chalmers KA, Cousins SE, Blazeby JM. Randomized controlled trials comparing gastric bypass, gastric band, and sleeve gastrectomy: A systematic review examining validity and applicability to wider clinical practice. Obes Rev 2024; 25:e13718. [PMID: 38346786 DOI: 10.1111/obr.13718] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/15/2023] [Revised: 01/17/2024] [Accepted: 01/17/2024] [Indexed: 04/18/2024]
Abstract
Consideration of how applicable the results of surgical trials are to clinical practice is important to inform decision-making. Randomized controlled trials comparing at least two surgical interventions (of gastric bypass, gastric band, and sleeve gastrectomy) for severe and complex obesity were examined using the PRagmatic Explanatory Continuum Indicator Summary-2 tool, to consider how applicable the trial results are to clinical practice, and the Risk of Bias 2 tool, to examine validity. MEDLINE, Embase, and CENTRAL databases were searched for studies published between November 2013 and June 2021, and 15 were identified. Using the PRagmatic Explanatory Continuum Indicator Summary-2 tool, three were classified as pragmatic, with good applicability to clinical practice. Ten had more explanatory domains but did include some pragmatic characteristics, and two were predominantly explanatory. This was due to some trial design features that would not be considered applicable to the wider clinical setting, including being single-centered, having prescribed intervention delivery methods, and intensive follow-up regimens. Only two trials had low risk of bias, of which one was considered pragmatic. Three had high risk of bias. Overall, few trials in bariatric surgery are pragmatic with low risk of bias. Well-designed pragmatic trials are needed to inform practice and reduce research waste.

Safety and Efficacy of LSG Versus LRYGB on Patients with Obesity: a Systematic Review and Meta-analysis from RCTs. Obes Surg 2024; 34:1138-1151. [PMID: 38351200 DOI: 10.1007/s11695-024-07076-w] [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: 10/02/2023] [Revised: 01/18/2024] [Accepted: 01/22/2024] [Indexed: 04/19/2024]
Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are the two most frequently performed techniques in treating obesity and its related comorbidities. We aimed to compare the clinical efficacy and safety of LSG with LRYGB in terms of short- and mid-term outcomes of weight loss, obesity-related comorbidities, and post-operative complications via a meta-analysis of RCTs. METHODS Clinical comparative RCTs on LSG and LRYGB were searched through PubMed, MEDLINE, and Web of Science databases from inception to August 2022. Pooled outcomes from the selected studies were discussed by the random-effect meta-analysis method. Quality assessment and risk of bias for selected RCTs were implemented, and all the statistical analyses were performed. RESULTS Twenty studies, including 1270 patients, were enrolled. Meta-analysis results indicated the great superior efficacy of LRYGB to LSG in BMI loss at 6 (MD -1.35 kg/m2, 95% CI: -2.07 to -0.62, p = 0.0003), 12 months (MD -1.09 kg/m2, 95% CI: -1.86 to -0.33, p = 0.005), and 36 months (MD -1.47 kg/m2, 95% CI: -2.77 to -0.16, p = 0.03) as well as %EWL gaining at 36 months. Significantly higher remission rates of T2DM and dyslipidemia were achieved by LRYGB at 12 months. Besides, better improvements for T2DM-related and lipid biochemical parameters were found favoring LRYGB. However, LSG resulted in a lower post-operative complication rate and shorter operating time. CONCLUSIONS Present meta-analysis results suggested that LRYGB was superior to LSG concerning short- and mid-term weight loss, short-term T2DM remission efficacy, and related biochemical parameters. LSG is favored for obviously fewer complications and shorter operating time.

Abstract
Sleeve gastrectomy (SG) has historically evolved from gastroplasty and anti-reflux procedures into one of the most commonly performed primary metabolic surgeries in the United States and worldwide. Initially initiated in the 1980s as part of the duodenal switch procedure, its standalone effectiveness and simplicity have led to increasing popularity globally. The rise in obesity rates transcends age boundaries, alarmingly affecting not only adults but also the younger demographic. This escalating trend is concerning, as it predisposes these populations to numerous future health complications, as well as highlighting the critical necessity for a safe and potent weight loss strategy. Although sleeve gastrectomy carries a higher risk for gastroesophageal reflux disease (GERD) compared to other bariatric procedures, it stands out as a reliable, safe and effective surgical solution for obesity. It is particularly beneficial for adolescents and patients with complex medical comorbidities, including, but not limited to, heart failure and immunocompromisation. It has also served as a bridge for transplants in morbidly obese patients with end-stage heart, liver and kidney disease due to its favorable safety profile.

Comparing Safety and Efficacy Outcomes of Gastric Bypass and Sleeve Gastrectomy in Patients With Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis. Cureus 2024; 16:e52796. [PMID: 38389648 PMCID: PMC10883263 DOI: 10.7759/cureus.52796] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/23/2024] [Indexed: 02/24/2024] Open
Abstract
Sleeve Gastrectomy (SG) could be done by the removal of a big portion of the stomach, leading to reduced amounts of food taken as a result of the smaller stomach size. In contrast, Roux-en-Y Gastric Bypass (RYGB) can be done by creating a small stomach pouch and rerouting a part of the small intestine, employing combined mechanisms of restriction and malabsorption to limit food intake and modify nutrient absorption. Our aim is to identify the most effective and safest surgical intervention for individuals with both Type 2 Diabetes Mellitus (T2DM) and obesity, considering both short and long-term outcomes. We will assess participants undergoing either SG or RYGB to determine the optimal surgical approach. We made a thorough search of PubMed, Cochrane Library, Scopus, and Web of Science databases up to November 2023. Our focus was on randomized controlled trials (RCTs) comparing the safety and efficacy of RYGB and SG in T2DM regarding any extractable data. We excluded studies of other designs, such as cohorts, case reports, case series, reviews, in vitro studies, postmortem analyses, and conference abstracts. Utilizing Review Manager 5.4, we performed a meta-analysis, combining risk ratios (RR) with a 95% confidence interval (CI) conducted for binary outcomes, while mean with SD and 95% CI are pooled for the continuous ones. The total number of participants in our study is 4,148 patients. Our analysis indicates superior outcomes in the group undergoing RYGB surgery compared to the SG group (RR = 0.76, 95% (CI) (0.66 to 0.88), P = 0.0002). The pooled data exhibited homogeneity (P = 0.51, I2 = 0%) after employing the leave-one-out method. For the 1-3 year period, six studies involving 332 patients with T2DM yielded non-significant results (RR = 0.83, 95% CI (0.66 to 1.06), P = 0.14) with homogeneity (P = 0.24, I2 = 28%). Conversely, the 5-10 year period, with six studies comprising 728 DM patients, demonstrated significant results (RR = 0.69, 95% CI (0.56 to 0.85), P = 0.14) and homogeneity (P = 0.84, I2 = 0%). In terms of total body weight loss, our findings indicate significantly higher weight loss with RYGB (mean difference (MD) = -6.13, 95% CI (-8.65 to -3.6), P > 0.00001). However, pooled data exhibited considerable heterogeneity (P > 0.00001, I2 = 93%). Subgroup analyses for the 1-3 year period (five studies, 364 DM patients) and 5-10 year period (six studies, 985 DM patients) also revealed significant differences favoring RYGB, with heterogeneity observed in both periods (1-3 years: P > 0.00001, I2 = 95%; 5-10 years: P = 0.001, I2 = 75%). RYGB demonstrated significant long-term improvement in diabetes remission and superior total body weight loss compared to SG. While no notable differences were observed in other efficacy outcomes, safety parameters require further investigation. no significant distinctions were found in any of the safety outcomes: hypertension (HTN), high-density lipoprotein (HDL), hyperlipidemia, fasting blood glucose, vomiting, low-density lipoprotein (LDL), and total cholesterol. Further research is essential to comprehensively assess safety outcomes for both surgical approaches.

Abstract
BACKGROUND Various prediction models of type 2 diabetes (T2D) remission have been externally verified internationally. However, long-term validated results after Roux-en-Y gastric bypass (RYGB) surgery are lacking. The best model for the Chinese population is also unknown. OBJECTIVES To evaluate the prediction effect of various prediction models on the long-term diabetes remission after RYGB in the Chinese population and to provide reference for clinical use. SETTING A retrospective clinical study at a university hospital. METHODS We retrospectively analyzed Chinese population data 5 years after RYGB and externally validated 11 predictive models to evaluate the predictive effect of each model on long-term T2D remission after RYGB. RESULTS We enrolled 84 patients. The mean body mass index was 41 kg/m2, and the percentage of excess weight loss (%EWL) was 72.3%. The mean glycated hemoglobin level was 8.4% preoperatively and decreased to 5.9% after 5 years. The 5-year postoperative complete and partial remission rates of T2D were 31% and 70.2%, respectively. The ABCD scoring model (sensitivity, 84%; specificity, 76%; area under the curve [AUC], .866) and the Panuzi et al. [34] study (sensitivity, 84%; specificity, 81%; AUC, .842) showed excellent results. In the Hosmer-Lemeshow goodness-of-fit test, calibration values for ABCD and Panuzi et al. [34] were .14 and .21, respectively. The predicted-to-observed ratios of ABCD and Panuzi et al. [34] were .83 and .88, respectively. CONCLUSIONS T2D was relieved to varying degrees 5 years after RYGB in patients with obesity. The prediction models in ABCD and the Panuzi et al. [34] studies showed the best prediction effects. ABCD was recommended for clinical use because of excellent predictive performance, good statistical test results, and simple and practical design features.

Abstract
Background Multidisciplinary screening of bariatric surgery candidates is recommended, and some centers provide an additional preparation program (APP) to optimize patients preoperatively. Objective To compare patients with APP to standard care 2 years after primary bariatric surgery regarding postoperative weight loss and resolution of obesity-related comorbidities. Methods A retrospective cohort study was conducted for patients undergoing primary Roux-en-Y gastric bypass and sleeve gastrectomy between September 2017 and March 2019. The first 12 months patients received an APP, after September 2018, the APP was no longer part of the weight loss trajectory. A multivariable linear regression model was built. Results Of the 384 patients receiving an APP advice, 50 were lost to follow up. In total, 192 (57%) received the APP and 142 (43%) received standard care. Percentage total weight loss after 2 years was significantly different, 28.8% for the APP group versus 32% for the standard group (p = 0.001). Postoperative weight loss after 2 years was increased in patients who had a gastric bypass, a higher baseline body mass index, and female gender in multivariable analysis. An APP was predictive for decreased postoperative weight. Diabetes mellitus was in remission significantly more often in the preparation group (84.1% of the cases) compared with the standard group (61.9%, p = 0.028). Conclusion A weight loss trajectory is at least as effective without additional preparation in terms of 2 years postoperative %TWL for primary gastric bypass and sleeve procedures. For comorbidities, diabetes mellitus was in remission more often in the APP group.

Abstract
AIM To systematically identify and appraise the international literature on the cost-effectiveness of metabolic surgery for the treatment of comorbid type 2 diabetes (T2D) and obesity. METHODS A systematic search was conducted in electronic databases and grey literature sources up to 20 January 2021. Economic evaluations in a T2D population or a subpopulation with T2D were eligible for inclusion. Screening, data extraction, critical appraisal of methodological quality (Consensus Health Economic Criteria list) and assessment of transferability (International Society for Pharmacoeconomics and Outcomes Research questionnaire) were undertaken in duplicate. The incremental cost-effectiveness ratio (ICER) was the main outcome. Costs were reported in 2020 Irish Euro. Cost-effectiveness was interpreted using willingness-to-pay (WTP) thresholds of €20,000 and €45,000/quality-adjusted life year (QALY). Due to heterogeneity arising from various sources, a narrative synthesis was undertaken. RESULTS Thirty studies across seventeen jurisdictions met the inclusion criteria; 16 specifically in a T2D population and 14 in a subpopulation with T2D. Overall, metabolic surgery was found to be cost-effective or cost-saving. Where undertaken, the results were robust to sensitivity and scenario analyses. Of the 30 studies included, 15 were considered high quality. Identified limitations included limited long-term follow-up data and uncertainty regarding the utility associated with T2D remission. CONCLUSION Published high-quality studies suggest metabolic surgery is a cost-effective or cost-saving intervention. As the prevalence of obesity and obesity-related diseases increases worldwide, significant investment and careful consideration of the resource requirements needed for metabolic surgery programmes will be necessary to ensure that service provision is adequate to meet demand.

Int J Obes (Lond) 2023:10.1038/s41366-023-01298-1. [PMID: 37005473 DOI: 10.1038/s41366-023-01298-1] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/08/2023] [Accepted: 03/14/2023] [Indexed: 04/04/2023]
Abstract
BACKGROUND Randomized controlled trials (RCTs) are regarded as high-level evidence, but the strength of their P values can be difficult to ascertain. The Fragility Index (FI) is a novel metric that evaluates the frailty of trial findings. It is defined as the minimum number of patients required to change from a non-event to event for the findings to lose statistical significance. This study aims to characterize the robustness of bariatric surgery RCTs by examining their FIs. METHODS A search was conducted in MEDLINE, EMBASE, and CENTRAL from January 2000 to February 2022 for RCTs comparing two bariatric surgeries with statistically significant dichotomous outcomes. Bivariate correlation was conducted to identify associations between FI and trial characteristics. RESULTS A total of 35 RCTs were included with a median sample size of 80 patients (Interquartile range [IQR] 58-109). The median FI was 2 (IQR 0-5), indicating that altering the status of two patients in one treatment arm would overturn the statistical significance of results. Subgroup analyses of RCTs evaluating diabetes-related outcomes produced a FI of 4 (IQR 2-6.5), while RCTs comparing Roux-en-Y gastric bypass and sleeve gastrectomy had an FI of 2 (IQR 0.5-5). Increasing FI was found to be correlated with decreasing P value, increasing sample size, increasing number of events, and increasing journal impact factor. CONCLUSION Bariatric surgery RCTs are fragile, with only a few patients required to change from non-events to events to reverse the statistical significance of most trials. Future research should examine the use of FI in trial design.

Abstract
Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) are the most commonly used bariatric procedures. There is an increasing awareness about a comorbidity-based indication for bariatric surgery regardless of weight (metabolic surgery). The best operation to mitigate obesity-associated comorbidities is a matter of controversy. This review is aimed at comparing LRYGB and LSG for the treatment of diabetes, hypertension, dyslipidemias, obstructive sleep apnea (OSA), and gastroesophageal reflux (GERD). We searched PubMed, MEDLINE, SCOPUS, Web of Science, and Cochrane library for articles comparing these two commonly used bariatric approaches. We identified 2,457 studies, 1,468 of which stood after the removal of duplications; from them, 81 full texts were screened and only 16 studies were included in the final meta-analysis. LRYGB was equal weight to LSG for diabetes (P-value = 0.10, odd ratio, 1.24, 95% CI, 0.96-1.61, I 2 for heterogeneity = 30%, P-value for heterogeneity, 0.14), and OSA (P-value = 0.38, odd ratio, 0.79, 95% CI, 0.47-1.33, I 2 for heterogeneity = 0.0%, P-value for heterogeneity, 0.98). However, LRYGB was superior to LSG regarding hypertension (P-value = 0.009, odd ratio, 1.55, 95% CI, 1.20-2.0, I 2 for heterogeneity = 0.0%, P-value for heterogeneity, 0.59), dyslipidemia (odd ratio, 2.18, 95% CI, 1.15-4.16, P-value for overall effect, 0.02), and GERD (P-value = 0.003, odd ratio, 3.16, 95% CI, 1.48-6.76). LRYGB was superior to LSG for gastroesophageal reflux, hypertension, and dyslipidemia remission. While the two procedures were equal regarding diabetes and obstructive sleep, further reviews comparing LSG, and one anastomosis gastric bypass are recommended.

Abstract
BACKGROUND Sleeve gastrectomy (SG) and Roux-en-Y Gastric Bypass (RYGB) are the two procedures used in the management of patient with obesity and type 2 diabetes mellitus (T2DM); however, it is still unclear which of the two is more efficient in the remission of type-2 diabetes mellitus. METHODS The aim of this study was to analyze the efficiency of RYGB and SG in the remission of type-2 diabetes mellitus after 1, 3 and 5 years of surgery. Three databases (i.e., PubMed, Scopus, Central and Web of Science) were searched. All randomized control trial studies with at least 12-year follow-up were selected with type-2 diabetes mellitus in patients undergoing Roux-en-Y Gastric Bypass or sleeve gastrectomy. The broad and the narrow criteria were lined with individual patients reported, being analyzed and pooled using the random-effects model. RESULTS The 15 selected articles, including 707 obese type 2 diabetes patients, met the eligibility criteria for this meta-analysis. RYGB when compared with SG shows increased broad remissions (RR=1.43, 95% CI: 1.13-1.80; P=0.003) and narrow remissions (RR=1.32, 95% CI: 1.15-1.58; P=0.003) after one year of surgery, and broad remissions 5 years after surgery (RR=1.58, 95% CI: 0.97-2.56; P=0.06). No significant difference was identified between the two groups in broad and narrow remissions 3 years after surgery and narrow remissions 5 years after surgery. CONCLUSIONS Our results suggest that RYGB was more effective in the remission of type-2 diabetes mellitus at 1 year and 5 years considering the broad and narrow criteria, while there was no difference found 3 years after surgery.

Abstract
Obesity is a chronic disease characterized by the abnormal or excessive accumulation of body fat, affecting more than 1 billion people worldwide. Obesity is commonly associated with other metabolic disorders, such as type 2 diabetes, non-alcoholic fatty liver disease, cardiovascular diseases, chronic kidney disease, and cancers. Factors such as a sedentary lifestyle, overnutrition, socioeconomic status, and other environmental and genetic conditions can cause obesity. Many molecules and signaling pathways are involved in the pathogenesis of obesity, such as nuclear factor (NF)-κB, Toll-like receptors (TLRs), adhesion molecules, G protein-coupled receptors (GPCRs), programmed cell death 1 (PD-1)/programmed death-ligand 1 (PD-L1), and sirtuin 1 (SIRT1). Commonly used strategies of obesity management and treatment include exercise and dietary change or restriction for the early stage of obesity, bariatric surgery for server obesity, and Food and Drug Administration (FDA)-approved medicines such as semaglutide and liraglutide that can be used as monotherapy or as a synergistic treatment. In addition, psychological management, especially for patients with obesity and distress, is a good option. Gut microbiota plays an important role in obesity and its comorbidities, and gut microbial reprogramming by fecal microbiota transplantation (FMT), probiotics, prebiotics, or synbiotics shows promising potential in obesity and metabolic syndrome. Many clinical trials are ongoing to evaluate the therapeutic effects of different treatments. Currently, prevention and early treatment of obesity are the best options to prevent its progression to many comorbidities.

Abstract
Obesity (BMI ≥ 30 kg/m2) with related comorbidities such as type 2 diabetes mellitus, cardiovascular disease, sleep apnea syndrome, and fatty liver disease is one of the most common preventable risk factors for cancer development worldwide. They are responsible for at least 40% of all newly diagnosed cancers, including colon, ovarian, uterine, breast, pancreatic, and esophageal cancer. Although various efforts are being made to reduce the incidence of obesity, its prevalence continues to spread in the Western world. Weight loss therapies such as lifestyle change, diets, drug therapies (GLP-1-receptor agonists) as well as bariatric and metabolic surgery are associated with an overall risk reduction of cancer. Therefore, these strategies should always be essential in therapeutical concepts in obese patients. This review discusses pre- and post-interventional aspects of bariatric and metabolic surgery and its potential benefit on cancer development in obese patients.

Abstract
OBJECTIVE This study aimed to determine which bariatric procedure allows patients to obtain the best weight-loss outcomes and a remission of type 2 diabetes. METHODS Databases were searched for randomized-controlled trials comparing Roux-en-Y gastric bypass (RYGB) with sleeve gastrectomy (SG) or one-anastomosis gastric bypass (OAGB). The mean difference (MD) or the relative risk was determined. RESULTS Twenty-five randomized-controlled trials were analyzed. Excess weight loss (EWL, percentage) was greater for RYGB patients at 3 years (MD: 11.93, p < 0.00001) and 5 years (MD: 13.11, p = 0.0004). Higher excess BMI loss (percentage) was found in RYGB at 1 year (MD: 11.66, p = 0.01). Total weight loss (percentage) was greater for RYGB patients after 3 months (MD: 2.41, p = 0.02), 6 months (MD: 3.83, p < 0.00001), 1 year (MD: 6.35, p < 0.00001), and 5 years (MD: 3.90, p = 0.005). No difference in terms of remission of type 2 diabetes was seen between RYGB and SG. EWL was significantly more important after OAGB than after RYGB after 1 year (MD: -10.82, p = 0.003). CONCLUSIONS RYGB is more efficient than SG in the midterm. OAGB offers greater EWL than RYGB after 1 year, but further evidence is needed to confirm this result.

Abstract
This study aims to explore the immediate effects of bariatric surgery on serum tryptophan–kynurenine pathway metabolites in individuals with type 2 diabetes and BMI > 30. With the goal of providing insight into the link between tryptophan pathway metabolites, type 2 diabetes, and chronic obesity-induced inflammation. This longitudinal study included 20 participants. Half were diagnosed with type 2 diabetes. 11 and 9 underwent RYGB and SG respectively. Blood samples were obtained at pre-operative and 3 months post-operative timepoints. Tryptophan and downstream metabolites of the kynurenine pathway were quantified with an ultrahigh-performance liquid chromatography tandem mass spectrometry with electrospray ionisation method. At 3 months post-operation, RYGB led to significant reductions in tryptophan, kynurenic acid and xanthurenic acid levels when compared to baseline. Significant reductions of the same metabolites after surgery were also observed in individuals with T2D irrespective of surgical procedure. These metabolites were significantly correlated with serum HbA1c levels and BMI. Bariatric surgery, in particular RYGB reduces serum levels of tryptophan and its downstream kynurenine metabolites. These metabolites are associated with T2D and thought to be potentially mechanistic in the systemic processes of obesity induced inflammation leading to insulin resistance. Its reduction after surgery is associated with an improvement in glycaemic control (HbA1c).

Abstract
The purpose of this systematic review was to study 4 different aspects of Roux-en-Y gastric bypass (RYBG) and sleeve gastrectomy (SG). Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) are two commonly performed bariatric procedures. This systematic review aims to compare RYGB with SG when it comes to weight changes, and cardiometabolic risk profile. Another aim was to evaluate laparoscopic and robotic techniques for both surgeries. PubMED, Cochrane Library, and JAMA Network were searched for articles evaluating RYGB and SG from 2005-2020. The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines were followed. Four different categories were analyzed comparing RYGB with SG as well as robotic versus laparoscopic approach. The Critical Appraisal Skills Program (CASP) checklist was used to assess the quality of evidence in the studies included in this systematic review. A total of 29 studies were included looking at different aspects of RYGB and SG. RYGB is superior to SG for weight loss, improved or complete remission of cholesterol and hypertensive medications. Consensus is lacking regarding decrease in BMI, total cholesterol, and triglycerides. There is lack of evidence regarding decrease of incidence of MI or stroke. For RYGB and SG, the majority of studies found that the robotic technique was more expensive and took longer. RYGB when compared with SG was associated with larger weight loss, decreased or cessation of cholesterol and hypertensive medications, and lower cholesterol. Decrease in BMI had varying results, with RYGB being superior in more studies, while there was no difference in other studies. There was a lack of evidence to support if RYGB or SG was superior to decreasing triglyceride levels. For both RYGB and SG, the robotic approach was costlier and took more operating time versus the laparoscopic approach.

Abstract
BACKGROUND Surgical quality assurance methods aim to ensure standardization and high quality of surgical techniques within multicenter randomized controlled trials (RCTs), thereby diminishing the heterogeneity of surgery and reducing biases due to surgical variation. This study aimed to establish the measures undertaken to ensure surgical quality within multicenter RCTs investigating bariatric and metabolic surgery, and their influence upon clinical outcomes. METHODS An electronic literature search was performed from the Embase, Medline, and Web of Science databases to identify multicenter RCTs investigating bariatric and metabolic surgery. Each RCT was evaluated against a checklist of surgical quality measures within 3 domain: (1) standardization of surgical techniques; (2) credentialing of surgical experience; and (3) monitoring of performance. Outcome measures were postoperative weight change and complications. RESULTS Nineteen multicenter RCTs were included in the analysis. Three studies undertook pretrial education of surgical standard. Fourteen studies described complete standardization of surgical techniques. Four studies credentialed surgeons by case volume prior to enrollment. Two studies used intraoperative or video evaluation of surgical technique prior to enrollment. Only two studies monitored performance during the study. Although there were limited quality assurance methods undertaken, utilization of these techniques was associated with reduced overall complications. Standardization of surgery was associated with reduced re-operation rates but did not influence postoperative weight loss. CONCLUSION The utilization of methods for surgical quality assurance are very limited within multicenter RCTs of bariatric and metabolic surgery. Future studies must implement surgical quality assurance methods to reduce variability of surgical performance and potential bias within RCTs.

Abstract
PURPOSE To determine whether sleeve gastrectomy (SG) or Roux-en-Y gastric bypass (RYGB) should be the optimal choice in patients stratified by diabetes duration and body mass index (BMI) level. METHODS Classification tree analysis was performed to identify the influential factors for surgical procedure selection in real setting. Meta-analyses stratified by influential factors were conducted to compare the complete diabetes remission rates between SG and RYGB. The cost-effectiveness analysis was performed when results from meta-analysis remain uncertain. RESULTS Among 3198 bariatric procedures in China, 824 (73%) SGs and 191 (17%) RYGBs were performed in patients with T2DM. Diabetes duration with a cutoff value of 5 years and BMI level with 35.5 kg/m2 were identified as the influential factors. For patients with diabetes duration > 5 years, RYGB showed a significant higher complete diabetes remission rate than SG at 1 year: 0.52 (95% confidence interval (CI): 0.46-0.58) versus 0.36 (95% CI: 0.30-0.42). For patients with diabetes duration ≤ 5 years and BMI ≥ 35.5 kg/m2, there was no significant difference between 2 procedures: 0.57 (95% CI: 0.43-0.71) for SG versus 0.66 (95% CI: 0.62-0.70) for RYGB. The cost-effectiveness ratios of SG and RYGB were 244.58 and 276.97 dollars per QALY, respectively. CONCLUSIONS For patients with diabetes duration > 5 years, RYGB was the optimal choice with regard to achieving complete diabetes remission at 1 year after surgery. However, for patients with diabetes duration ≤ 5 years and BMI ≥ 35.5 kg/m2, SG appeared to provide a cost-effective choice.

Abstract
Introduction Comparative data on long-term outcomes of mechanistically different bariatric operations are scarce. Methods In this prospective, observational study, consecutive patients with severe obesity were studied using a predefined reoperation algorithm to determine long-term health outcomes after bariatric surgery (BS): adjustable gastric banding (AGB), Roux-en-Y gastric bypass (RYGB), or biliopancreatic diversion (BPD). All patients were assessed for mortality, postoperative weight loss, rate of reoperation, comorbidities, and quality of life (QoL) 8 years after surgery. Results Between 1996 and 2008, 2364 Swiss patients, with a mean body mass index of 43 ± 7 kg/m2 (mean ± SD) underwent AGB (n = 1404), RYGB (n = 790), or BPD (n = 170). Two thousand two hundred twenty-eight (94%) were followed for 8 years after BS. Eight-year mortality of the whole study group was 34.3 per 104 person-years. Percent excessive weight loss at 8 years was 56.7 ± 1.4% (95% confidence interval) in AGB, 62.5 ± 2.4% in RYGB and 64.8+-3.0% in BPD. The rate of major reoperation was highest in AGB and significantly lower in RYGB and BPD (63.4 vs 54.3 vs 47.2 per 103 person-years, P < 0.001). Remission of comorbidities was observed across all 3 groups, with key improvement (P < 0.01) in esophagitis in the RYGB group, and type 2 diabetes (T2D) (>60%) in procedures involving duodenal exclusion. Total improvement in QoL was similar between the 3 types of operations but was strongly correlated with weight loss preservation (P < 0.001). Conclusions BS, at the expense of a high reoperation rate but low procedural mortality, considerably improves the QoL and results in sustained remission of comorbidities, especially T2D using a predefined reoperation algorithm developed to prevent weight regain and operation-specific complications.
