Benefits of metabolic surgery on macrovascular outcomes in adult patients with type 2 diabetes: a systematic review and meta-analysis. Surg Obes Relat Dis 2024; 20:202-212. [PMID: 37845131 DOI: 10.1016/j.soard.2023.08.016] [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: 03/21/2023] [Revised: 08/02/2023] [Accepted: 08/28/2023] [Indexed: 10/18/2023]
Abstract
Type 2 diabetes (T2D) is a chronic metabolic disorder that affects millions of individuals associated with an increased risk of mortality and macrovascular complications. We aimed to synthesize the benefit of metabolic surgery (MS) on macrovascular outcomes in adult patients with T2D.We included both cohort studies and randomized controlled trials (RCTs) that evaluated MS added to medical therapy compared with medical therapy alone in the treatment of adult patients with T2D. Studies must have evaluated the incidence of any macrovascular complication of the disease for a period of at least 6 months. We performed our search using PubMed, Scopus, EMBASE, Web of Science, and COCHRANE Central database which was performed from inception date until March 2022. The trial protocol was previously registered at PROSPERO (CRD42021243739). A total of 6338 references were screened throughout the selection process from which 16 studies involving 179,246 participants fulfilled inclusion criteria. MS reduced the risk of any cardiovascular event by 44% (relative risk .56 [95% CI, .42-.75]; P = < .001), myocardial infarction by 54% (.46 [95% CI, .26-.83]; P = .009), coronary artery disease by 40% (.60 [95% CI, .42-.85]; P = .004) and heart failure by 71% (.29 [95% CI, .14-.61]; P = .001). It also provided a risk reduction of stroke by 29% (.71 [95% CI, .51-.99]; P = .04) and 38% (.62 [95% CI, .46-.85]; P = .001) for cerebrovascular events. On mortality, MS yields a risk reduction of 55% (.45 [95% CI, .36-.57]; P <.001) in overall mortality and 69% in cardiovascular mortality (relative risk .31 [95% CI, .22-.42]; P < .001). Peripheral vascular disease risk was also reduced. MS in adult patients with T2D can reduce the risk of mortality and of any macrovascular outcomes. However, there is a need for the planning of randomized clinical trials to further analyze and confirm the results.

Abstract
Obesity is an increasingly widespread disease worldwide because of lifestyle changes. It is associated with an increased risk of cardiovascular disease, primarily type 2 diabetes mellitus, with an increase in major cardiovascular adverse events. Bariatric surgery has been shown to be able to reduce the incidence of obesity-related cardiovascular disease and thus overall mortality. This result has been shown to be the result of hormonal and metabolic effects induced by post-surgical anatomical changes, with important effects on multiple hormonal and molecular axes that make this treatment more effective than conservative therapy in determining a marked improvement in the patient's cardiovascular risk profile. This review, therefore, aimed to examine the surgical techniques currently available and how these might be responsible not only for weight loss but also for metabolic improvement and cardiovascular benefits in patients undergoing such procedures.

Abstract
PURPOSE Metabolic and bariatric surgery (MBS) can exert effective function on glycemic control. The present study aimed to estimate the risk of MACE among obese patients with diabetes after MBS. MATERIALS AND METHODS Systematic search of PubMed, Embase, Medline, and Web of Science was performed for studies published before 20th February 2023. The odds ratio (OR) corresponding to the 95% confidence interval (95% CI) was used to assess the outcome. The statistical heterogeneity among studies was assessed with the Q-test and I2 statistics. RESULTS Fifteen cohort studies with 122,361 obese patients with diabetes were available for analysis. Our meta-analysis found significantly decreased morbidity and mortality of MACE (OR = 0.65, 95% CI = 0.59-0.72, I2 = 62.8% for morbidity, OR = 0.49, 95% CI = 0.36-0.67, I2 = 68.7% for mortality). Subgroup analysis revealed MBS decreased cerebrovascular disease, coronary artery disease, atrial fibrillation, heart failure, myocardial infarction, and stroke risk. CONCLUSION Our meta-analysis indicated that MBS for obese patients with diabetes is beneficial to decreasing MACE risk. Moreover, further studies estimating the functional effect may eventually provide a better and comprehensive understanding of the effect on different populations.

Abstract
Obesity is a major public health problem that is associated with serious comorbidities and premature mortality. Cardiovascular disease (CVD) is the major cause of morbidity and mortality associated with obesity. Lifestyle modifications, pharmacological therapy, and weight reduction surgery are the major interventions to date available for obesity management. Bariatric surgery has been increasingly utilized as a therapeutic option for obesity. In this meta-analysis, we aim to assess the effects of bariatric surgery on CVD outcomes and cardiovascular mortality. This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. PubMed, Embase, Cochrane Library, Google Scholar, and Web of Science were searched until 03/01/2022. Our search included three types of bariatric surgery: Roux-en-Y gastric bypass (RYGB), sleeve gastrectomy, and gastric banding (GB). All were searched in conjunction with "coronary artery disease," "ischemic heart disease," "myocardial infarction," "cerebrovascular accident," "stroke," "atrial fibrillation," "heart failure," "arrhythmias," and "mortality." We included 49 studies meeting the study criteria. Bariatric surgery showed a beneficial effect on coronary artery disease (CAD) (hazard ratio (HR) of 0.68 {95% confidence interval (CI): 0.52-0.91}, p = 0.008), myocardial infarction (MI) (HR of 0.53 {95% CI: 0.44-0.64}, p < 0.01) heart failure (HF) (HR of 0.45 {95% CI: 0.37-0.55}, p < 0.01), cerebrovascular accident (CVA) (HR of 0.68 {95% CI: 0.59-0.78}, p < 0.01), and cardiovascular mortality (HR of 0.48 {95% CI: 0.40-0.57}, p < 0.01). The effect on atrial fibrillation (AF) did not reach statistical significance: HR of 0.81 (95% CI: 0.65-1.01), p = 0.07. Our study, that is, an updated meta-analysis, including the three types of procedure, confirms beneficial effects on the major CVD outcomes, including coronary artery disease, myocardial infarction, cerebrovascular accident, and heart failure, and on CVD mortality. This study provides updated insights into the long-term CV effects of bariatric surgery, an increasingly common intervention for obesity.

Nutritional Outcomes One Year after One Anastomosis Gastric Bypass Compared to Sleeve Gastrectomy. Nutrients 2022; 14:nu14132597. [PMID: 35807778 PMCID: PMC9268580 DOI: 10.3390/nu14132597] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2022] [Revised: 06/10/2022] [Accepted: 06/20/2022] [Indexed: 02/06/2023] Open
Abstract
One Anastomosis Gastric Bypass (OAGB) and Sleeve Gastrectomy (SG) are the most common bariatric procedures performed worldwide. SG is a restrictive procedure whereas OAGB involves malabsorption as well, supposing a risk of deficiency development post OAGB. The aim of the study was to compare nutritional deficiencies and metabolic markers one year after the procedures, while adhering to the current protocols. Retrospective analysis was performed for data on 60 adults undergoing primary OAGB, compared to 60 undergoing primary SG. Mean pre-surgery BMI for SG was 42.7 kg/m2 and 43.3 kg/m2 for OAGB. A multidisciplinary team followed up with the patients at least 3 times during the first year. Mean weight loss was 39.0 kg for SG and 44.1 kg for OAGB. The OAGB group presented a significantly sharper decline in T.Chol and a trend for sharper LDL decrease; a higher increase in folate and a trend for a greater decrease in albumin and hemoglobin were observed in OAGB. For vitamin B12, D, iron and ferritin, no difference was observed between the treatment groups, although there were some in-group differences. Nutritional recommendations and adopted supplement plans minimize the risk of deficiencies and result in improvement in metabolic biomarkers one year after OAGB, which was comparable to SG.

Abstract
Aims Obesity is a global health problem, associated with significant morbidity and mortality, often due to cardiovascular (CV) diseases. While bariatric surgery is increasingly performed in patients with obesity and reduces CV risk factors, its effect on CV disease is not established. We conducted a systematic review and meta-analysis to evaluate the effect of bariatric surgery on CV outcomes, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline. Methods and results PubMed and Embase were searched for literature until August 2021 which compared bariatric surgery patients to non-surgical controls. Outcomes of interest were all-cause and CV mortality, atrial fibrillation (AF), heart failure (HF), myocardial infarction, and stroke. We included 39 studies, all prospective or retrospective cohort studies, but randomized outcome trials were not available. Bariatric surgery was associated with a beneficial effect on all-cause mortality [pooled hazard ratio (HR) of 0.55; 95% confidence interval (CI) 0.49–0.62, P < 0.001 vs. controls], and CV mortality (HR 0.59, 95% CI 0.47–0.73, P < 0.001). In addition, bariatric surgery was also associated with a reduced incidence of HF (HR 0.50, 95% CI 0.38–0.66, P < 0.001), myocardial infarction (HR 0.58, 95% CI 0.43–0.76, P < 0.001), and stroke (HR 0.64, 95% CI 0.53–0.77, P < 0.001), while its association with AF was not statistically significant (HR 0.82, 95% CI 0.64–1.06, P = 0.12). Conclusion The present systematic review and meta-analysis suggests that bariatric surgery is associated with reduced all-cause and CV mortality, and lowered incidence of several CV diseases in patients with obesity. Bariatric surgery should therefore be considered in these patients.

Impact of Bariatric Surgery on Pulse Wave Velocity as a Measure of Arterial Stiffness: a Systematic Review and Meta-analysis. Obes Surg 2021; 31:4461-4469. [PMID: 34319469 DOI: 10.1007/s11695-021-05611-7] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2021] [Revised: 07/17/2021] [Accepted: 07/20/2021] [Indexed: 12/28/2022]
Abstract
PURPOSE Weight loss during post-bariatric surgery period has been linked to both reduced ASCVD mortality and overall mortality. Atherosclerosis causes arteries to lose their elasticity and become more stiff resulting in increased pulse wave velocity (PWV). It has been revealed that PWV favorably predicts subsequent ASCVDs. The goal of this systematic review and meta-analysis was to see how bariatric surgery affected PWV, an index of arterial stiffness. MATERIALS AND METHODS A systematic literature search in four databases was performed. Also, Cochrane guidelines were reviewed to determine bias possibility in the related studies. Comprehensive Meta-Analysis (CMA) V2 software is used to conduct the meta-analysis. Studies were evaluated regarding heterogeneity in design, populations under investigation, and treatment duration using random-effects model and the generic inverse variance weighting approach. A random-effect meta-regression approach was used to investigate the association with the estimated effect size. Evaluation of funnel plot, Egger's weighted regression, and Begg's rank correlation tests were utilized to estimate the presence of publication bias in the meta-analysis. RESULTS The results of meta-analysis on 13 trials including 1426 individuals demonstrated a remarkable decline of PWV after bariatric surgery (WMD: -0.652, 95% CI: -1.004, -0.301, p<0.001). The random-effects meta-regression revealed no evidence of significant correlation between the changes in PWV and initial BMI, BMI changes, or duration of follow-up. CONCLUSION The decrease of PWV might be utilized as an independent surrogate marker of improvement of ASCVD risk after bariatric surgery.

Abstract
OBJECTIVES To assess completeness and validity of bariatric surgery codes in the UK Clinical Practice Research Datalink (CPRD) GOLD compared with Hospital Episodes Statistics (HES). METHODS We conducted a validation study among patients in the UK-based CPRD GOLD with linkage to HES (1998 to 2017). Since the same surgery codes are used for bariatric and other gastrointestinal surgery we assessed code distribution patterns used in patients with bariatric versus other gastrointestinal surgery by presence of other conditions such as obesity and gastrointestinal cancer. We developed algorithms to identify bariatric surgery and calculated validity measures (ie, positive/negative predictive value [PPV/NPV], sensitivity, and specificity) of each in CPRD GOLD compared with HES (gold standard). RESULTS Among 7 357 007 available patients we identified 10 190 patients who had a total of 14 046 potential bariatric surgery codes in CPRD GOLD and/or HES. Surgery code patterns differed between bariatric surgery and assumed other gastrointestinal surgery. The sensitivity of CPRD GOLD bariatric surgery coding improved from an overall of 56% to 69-71% when applying stricter algorithms (ie, in obese patients or obese, gastrointestinal disease/complication free patients) but PPVs remained at 53%-55%. NPVs and specificities of CPRD GOLD bariatric surgery coding achieved ≥99.8% for all algorithms. CONCLUSION Our results suggest that using CPRD GOLD and HES data and a wide selection of surgery codes will result in the most complete and accurate capture of bariatric surgery events. Validity measures of CPRD GOLD bariatric surgery codes were identical in obese patients and more restrictive populations.

Abstract
Weight reduction continues to be first-line therapy in the treatment of hypertension (HTN). However, the long-term effect of bariatric malabsorptive surgical techniques such as Roux-en-Y Gastric Bypass (RYGB) surgery in the management of hypertension (HTN) is less clear. African Americans (AA) are disproportionately affected by obesity and hypertension and have inconsistent outcomes after bariatric surgery (BS). Despite a plethora of bariatric literature, data about characteristics of a predominantly AA bariatric hypertensive cohort including hypertension in obese (HIO) are scarce and underreported. The aims of this study were, (1) to describe the preoperative clinical characteristics of HIO with respect to HTN status and age, and (2) to identify predictors of HTN resolution one year after RYGB surgery in an AA bariatric cohort enrolled at the Howard University Center for Wellness and Weight Loss Surgery (HUCWWS). In the review of 169 AA bariatric patients, the average BMI was 48.50 kg/m2 and the average age was 43.86 years. Obese hypertensive patients were older (46 years vs. 37.89 years; p < .0001); had higher prevalence of diabetes mellitus (DM, 43.09% vs. 10.87%; p < .0001) and dyslipidemia (38.2% vs. 13.04%; p 0.002). Hypertensive AA who were taking ≥ 2 antihypertensive medications prior to RYGB were 18 times less likely to experience HTN resolution compared to hypertensive AA taking 0-1 medications, who showed full or partial response. Also, HIO was less likely to resolve after RYGB surgery in patients who needed ≥ 2 antihypertensive medications prior to surgical intervention.

The Impact of Bariatric Surgery on Incident Microvascular Complications in Patients With Type 2 Diabetes: A Matched Controlled Population-Based Retrospective Cohort Study. Diabetes Care 2021; 44:116-124. [PMID: 33444160 PMCID: PMC7783931 DOI: 10.2337/dc20-0571] [Citation(s) in RCA: 12] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2020] [Accepted: 10/07/2020] [Indexed: 02/03/2023]
Abstract
OBJECTIVE To assess the impact of bariatric surgery (BS) on incident microvascular complications of diabetes-related foot disease (DFD), sight-threatening diabetic retinopathy (STDR), and chronic kidney disease (CKD) in patients with type 2 diabetes and obesity. RESEARCH DESIGN AND METHODS A retrospective matched, controlled population-based cohort study was conducted of adults with type 2 diabetes between 1 January 1990 and 31 January 2018 using IQVIA Medical Research Data (IMRD), a database of primary care electronic records. Each patient with type 2 diabetes who subsequently had BS (surgical group) was matched on the index date with up to two patients with type 2 diabetes who did not have BS (nonsurgical group) within the same general practice by age, sex, preindex BMI, and diabetes duration. RESULTS Included were 1,126 surgical and 2,219 nonsurgical participants. In the study population 2,261 (68%) were women. Mean (SD) age was 49.87 (9.3) years vs. 50.12 (9.3) years and BMI was 46.76 (7.96) kg/m2 vs. 46.14 (7.49) kg/m2 in the surgical versus nonsurgical group, respectively. In the surgical group, 22.1%, 22.7%, 52.2%, and 1.1% of patients had gastric band, sleeve gastrectomy, Roux-en-Y gastric bypass (RYGB), and duodenal switch, respectively. Over a median follow-up of 3.9 years (interquartile range 1.8-6.4), BS was associated with reduction in incident combined microvascular complications (adjusted hazard ratio 0.53, 95% CI 0.43-0.66, P < 0.001), DFD (0.61, 0.50-0.75, P < 0.001), STDR (0.66, 0.44-1.00, P = 0.048), and CKD (0.63, 0.51-0.78, P < 0.001). Analysis based on the type of surgery showed that all types of surgery were associated with a favorable impact on the incidence of composite microvascular complications, with the greatest reduction for RYGB. CONCLUSIONS BS was associated with a significant reduction in incident diabetes-related microvascular complications.

Chen TY, Liu CT, Chung CH, Hung SL, Chien WC, Chen JH. Bariatric surgery may provide better protection than uvulopalatopharyngoplasty against major adverse cardiovascular events in obese patients with obstructive sleep apnea. Surg Obes Relat Dis 2020; 17:780-791. [PMID: 33423961 DOI: 10.1016/j.soard.2020.11.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2020] [Revised: 11/13/2020] [Accepted: 11/20/2020] [Indexed: 12/26/2022]
Abstract
BACKGROUND The major adverse cardiovascular events (MACE) risk is unclear among Asian obese patients with obstructive sleep apnea (OSA) who undergo bariatric surgery (BS) or uvulopalatopharyngoplasty (UPPP). OBJECTIVES We aimed to evaluate differences between Asian obese patients with OSA who underwent BS or UPPP regarding MACE. SETTING The Longitudinal Health Insurance Database, a subset of the NHI Research Database (NHIRD) originated from the National Health Insurance (NHI) program in Taiwan, which comprises information from 2 million randomly sampled individuals between 2000 and 2015. METHODS Participants aged 18-55 years whose diagnoses corresponded with codes in the International Classification of Diseases, Ninth Revision, Clinical Modification for BS, UPPP, obesity, and OSA were included in this population-based, matched cohort study of Taiwan's insurance claims data gathered between 2000 and 2015. Obese patients with OSA who underwent BS or UPPP were propensity score matched; the study's outcome was MACE. RESULTS A total of 1336 patients, comprising 668 in each of the BS and UPPP cohorts, were enrolled. After a mean follow-up period of 8.51 years, 166 patients, comprising 52 in the BS cohort and 114 in the UPPP cohort, experienced MACE. The adjusted hazard ratio (aHR) for MACE was .592 (95% confidence interval [CI] = .324-.789; P < .001). The BS cohort had lower risks of stroke (aHR = .663; 95% CI = .312-.890; P < .001), myocardial infarction (aHR = .116; 95% CI = .052-.135; P < .001), and mortality (aHR = .779; 95% CI = .423-.948; P = .001) than the UPPP cohort. CONCLUSION BS may provide greater protection against MACE than UPPP in Asian obese patients with OSA. Additional mechanistic research is needed to clarify differences between BS and UPPP in these patients.

Abstract
PURPOSE OF REVIEW Knowledge regarding postoperative outcomes after bariatric and metabolic surgery continues to evolve. This review highlights key findings in outcomes research over the last 5 years related to weight loss, remission of obesity-related disease, reflux, revisional surgery, robotic-assisted surgical platforms, and adolescent populations. RECENT FINDINGS Sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) produce similar weight loss patterns at 5 years, while duodenal switch (BPD/DS) and related procedures are associated with maximal weight loss overall and optimal resolution of obesity-related comorbidities. Remission of type 2 diabetes mellitus (T2DM) following surgery is more likely in patients who are not insulin dependent prior to surgery. Bariatric and metabolic surgery offers a significant protective effect against coronary artery disease (CAD) and associated interventions in both diabetic and nondiabetic patients, as well as heart failure (HF). Gastroesophageal reflux disease (GERD) and dysphagia following SG are common, and routine endoscopic surveillance for Barrett's esophagus may be of significant utility. Robotic-assisted laparoscopic platforms concur similar outcomes to laparoscopic intervention, with a potential benefit in high BMI patients. Revisional surgery is most commonly performed for weight regain and/or inadequate weight loss following an index procedure, or reflux, and generally characterized by higher postoperative complication rates and longer inpatient lengths of stay (LOS). Surgical intervention in adolescent populations has similar weight loss and postoperative complication profiles to those seen in adult populations, with improved outcomes related to T2DM. Bariatric and metabolic surgery continues to evolve as a treatment for obesity and obesity-related comorbidities. While effective for weight loss and remission of obesity-related disease, SG is associated with high rates of postoperative GERD.
