Optimizing antithrombotic therapy in patients with coexisting cardiovascular and gastrointestinal disease.

Balancing the safety and efficacy of antithrombotic agents in patients with gastrointestinal disorders is challenging because of the potential for interference with the absorption of antithrombotic drugs and for an increased risk of bleeding. In this Review, we address considerations for enteral antithrombotic therapy in patients with cardiovascular disease and gastrointestinal comorbidities. For those with gastrointestinal bleeding (GIB), we summarize a general scheme for risk stratification and clinical evidence on risk reduction approaches, such as limiting the use of concomitant medications that increase the risk of GIB and the potential utility of gastrointestinal protection strategies (such as proton pump inhibitors or histamine type 2 receptor antagonists). Furthermore, we summarize the best available evidence and potential gaps in our knowledge on tailoring antithrombotic therapy in patients with active or recent GIB and in those at high risk of GIB but without active or recent GIB. Finally, we review the recommendations provided by major medical societies, highlighting the crucial role of teamwork and multidisciplinary discussions to customize the antithrombotic regimen in patients with coexisting cardiovascular and gastrointestinal diseases.

Current recommendations for procedure selection in class I and II obesity developed by an expert modified Delphi consensus.

Metabolic and bariatric surgery (MBS) is widely considered the most effective option for treating obesity, a chronic, relapsing, and progressive disease. Recently, the American Society of Metabolic and Bariatric Surgery (ASMBS) and the International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) issued new guidelines on the indications for MBS, which have superseded the previous 1991 National Institutes of Health guidelines. The aim of this study is to establish the first set of consensus guidelines for selecting procedures in Class I and II obesity, using an Expert Modified Delphi Method. In this study, 78 experienced bariatric surgeons from 32 countries participated in a two-round Modified Delphi consensus voting process. The threshold for consensus was set at an agreement or disagreement of ≥ 70.0% among the experts. The experts reached a consensus on 54 statements. The committee of experts reached a consensus that MBS is a cost-effective treatment option for Class II obesity and for patients with Class I obesity who have not achieved significant weight loss through non-surgical methods. MBS was also considered suitable for patients with Type 2 diabetes mellitus (T2DM) and a body mass index (BMI) of 30 kg/m2 or higher. The committee identified intra-gastric balloon (IGB) as a treatment option for patients with class I obesity and endoscopic sleeve gastroplasty (ESG) as an option for patients with class I and II obesity, as well as for patients with T2DM and a BMI of ≥ 30 kg/m2. Sleeve gastrectomy (1) and Roux-en-Y gastric bypass (RYGB) were also recognized as viable treatment options for these patient groups. The committee also agreed that one anastomosis gastric bypass (OAGB) is a suitable option for patients with Class II obesity and T2DM, regardless of the presence or severity of obesity-related medical problems. The recommendations for selecting procedures in Class I and II obesity, developed through an Expert Modified Delphi Consensus, suggest that the use of standard primary bariatric endoscopic (IGB, ESG) and surgical procedures (SG, RYGB, OAGB) are acceptable in these patient groups, as consensus was reached regarding these procedures. However, randomized controlled trials are still needed in Class I and II Obesity to identify the best treatment approach for these patients in the future.

Long-Term Outcomes of Medical Management vs Bariatric Surgery in Type 2 Diabetes.

Importance: Randomized clinical trials of bariatric surgery have been limited in size, type of surgical procedure, and follow-up duration. Objective: To determine long-term glycemic control and safety of bariatric surgery compared with medical/lifestyle management of type 2 diabetes. Design, Setting, and Participants: ARMMS-T2D (Alliance of Randomized Trials of Medicine vs Metabolic Surgery in Type 2 Diabetes) is a pooled analysis from 4 US single-center randomized trials conducted between May 2007 and August 2013, with observational follow-up through July 2022. Intervention: Participants were originally randomized to undergo either medical/lifestyle management or 1 of the following 3 bariatric surgical procedures: Roux-en-Y gastric bypass, sleeve gastrectomy, or adjustable gastric banding. Main Outcome and Measures: The primary outcome was change in hemoglobin A1c (HbA1c) from baseline to 7 years for all participants. Data are reported for up to 12 years. Results: A total of 262 of 305 eligible participants (86%) enrolled in long-term follow-up for this pooled analysis. The mean (SD) age of participants was 49.9 (8.3) years, mean (SD) body mass index was 36.4 (3.5), 68.3% were women, 31% were Black, and 67.2% were White. During follow-up, 25% of participants randomized to undergo medical/lifestyle management underwent bariatric surgery. The median follow-up was 11 years. At 7 years, HbA1c decreased by 0.2% (95% CI, -0.5% to 0.2%), from a baseline of 8.2%, in the medical/lifestyle group and by 1.6% (95% CI, -1.8% to -1.3%), from a baseline of 8.7%, in the bariatric surgery group. The between-group difference was -1.4% (95% CI, -1.8% to -1.0%; P < .001) at 7 years and -1.1% (95% CI, -1.7% to -0.5%; P = .002) at 12 years. Fewer antidiabetes medications were used in the bariatric surgery group. Diabetes remission was greater after bariatric surgery (6.2% in the medical/lifestyle group vs 18.2% in the bariatric surgery group; P = .02) at 7 years and at 12 years (0.0% in the medical/lifestyle group vs 12.7% in the bariatric surgery group; P < .001). There were 4 deaths (2.2%), 2 in each group, and no differences in major cardiovascular adverse events. Anemia, fractures, and gastrointestinal adverse events were more common after bariatric surgery. Conclusion and Relevance: After 7 to 12 years of follow-up, individuals originally randomized to undergo bariatric surgery compared with medical/lifestyle intervention had superior glycemic control with less diabetes medication use and higher rates of diabetes remission. Trial Registration: ClinicalTrials.gov Identifier: NCT02328599.

Metabolic and Bariatric Surgery in Patients with Obesity Class V (BMI > 60 kg/m2): a Modified Delphi Study.

BACKGROUND: Metabolic and bariatric surgery (MBS) is the preferred method to achieve significant weight loss in patients with Obesity Class V (BMI > 60 kg/m2). However, there is no consensus regarding the best procedure(s) for this population. Additionally, these patients will likely have a higher risk of complications and mortality. The aim of this study was to achieve a consensus among a global panel of expert bariatric surgeons using a modified Delphi methodology. METHODS: A total of 36 recognized opinion-makers and highly experienced metabolic and bariatric surgeons participated in the present Delphi consensus. 81 statements on preoperative management, selection of the procedure, perioperative management, weight loss parameters, follow-up, and metabolic outcomes were voted on in two rounds. A consensus was considered reached when an agreement of ≥ 70% of experts' votes was achieved. RESULTS: A total of 54 out of 81 statements reached consensus. Remarkably, more than 90% of the experts agreed that patients should be notified of the greater risk of complications, the possibility of modifications to the surgical procedure, and the early start of chemical thromboprophylaxis. Regarding the choice of the procedure, SADI-S, RYGB, and OAGB were the top 3 preferred operations. However, no consensus was reached on the limb length in these operations. CONCLUSION: This study represents the first attempt to reach consensus on the choice of procedures as well as perioperative management in patients with obesity class V. Although overall consensus was reached in different areas, more research is needed to better serve this high-risk population.

Trends and Outcomes Associated With Bariatric Surgery and Pharmacotherapies With Weight Loss Effects Among Patients With Heart Failure and Obesity.

BACKGROUND: Utilization patterns of bariatric surgery among older patients with heart failure (HF), and the associations with cardiovascular outcomes, are not well known. METHODS: Medicare beneficiaries with HF and at least class II obesity from 2013 to 2020 were identified with Medicare Provider Analysis and Review 100% inpatient files and Medicare 5% outpatient files. Patients who underwent bariatric surgery were matched to controls in a 1:2 ratio (matched on exact age, sex, race, body mass index, HF encounter year, and HF hospitalization rate pre-surgery/matched period). In an exploratory analysis, patients prescribed pharmacotherapies with weight loss effects (semaglutide, liraglutide, naltrexone-bupropion, or orlistat) were identified and matched to controls with a similar strategy in addition to HF medical therapy data. Cox models evaluated associations between weight loss therapies (as a time-varying covariate) and mortality risk and HF hospitalization rate (calculated as the rate of HF hospitalizations following index HF encounter per 100 person-months) during follow-up. RESULTS: Of 298 101 patients with HF and body mass index ≥35 kg/m2, 2594 (0.9%) underwent bariatric surgery (45% men; mean age, 56.2 years; mean body mass index, 51.5 kg/m2). In propensity-matched analyses over a median follow-up of 4.7 years, bariatric surgery was associated with lower risk of all-cause mortality (HR, 0.55 [95% CI, 0.49-0.63]; P<0.001), greater reduction in HF hospitalization rate (rate ratio, 0.72 [95% CI, 0.67-0.77]; P<0.001), and lower atrial fibrillation risk (HR, 0.78 [95% CI, 0.65-0.93]; P=0.006). Use of pharmacotherapies with weight loss effects was low (4.8%), with 96.3% prescribed GLP-1 (glucagon-like peptide-1) agonists (semaglutide, 23.6%; liraglutide, 72.7%). In propensity-matched analysis over a median follow-up of 2.8 years, patients receiving pharmacotherapies with weight loss effects (versus matched controls) had a lower risk of all-cause mortality (HR, 0.82 [95% CI, 0.71-0.95]; P=0.007) and HF hospitalization rate (rate ratio, 0.87 [95% CI, 0.77-0.99]; P=0.04). CONCLUSIONS: Bariatric surgery and pharmacotherapies with weight loss effects are associated with a lower risk of adverse outcomes among older patients with HF and obesity; however, overall utilization remains low.

Can Nonalcoholic Steatohepatitis Be Surgically Cured?: Liver Histologic Comparison After Metabolic Surgery Versus Usual Care.

OBJECTIVE: To compare histologic outcomes in patients with fibrotic nonalcoholic steatohepatitis (NASH) and obesity after metabolic surgery versus nonsurgical care. BACKGROUND: There are no published data comparing the effects of metabolic surgery versus nonsurgical care on histologic progression of NASH. METHODS: Repeat liver biopsies were performed in patients with body mass index >30 kg/m 2 at a US health system whose baseline liver biopsy between 2004 and 2016 confirmed a histologic diagnosis of NASH including the presence of liver fibrosis, but without cirrhosis. Baseline characteristics of liver histology for patients who underwent simultaneous liver biopsy at the time of metabolic surgery were balanced with a nonsurgical control group using overlap weighting methods. The primary composite endpoint required both resolution of NASH and improvement of at least 1 fibrosis stage in the repeat liver biopsy. RESULTS: A total of 133 patients (42 metabolic surgery and 91 nonsurgical controls) had a repeat liver biopsy with a median interval of 2 years. Overlap weighting provided balance for baseline histologic disease activity, fibrosis stage, and time interval between liver biopsies. In overlap-weighted patients, 50.1% in the surgical and 12.1% in the nonsurgical group met the primary endpoint (odds ratio=7.3; 95% CI, 2.8-19.2, P <0.001). NASH resolution and fibrosis improvement occurred in 68.5% and 64.1% of surgical patients, respectively. Surgical and nonsurgical patients who met the primary endpoint lost more weight than their counterparts who did not meet the primary endpoint [mean weight loss difference in the surgical group: 12.2% (95% CI, 7.3%-17.2%) and in the nonsurgical group: 11.6% (95% CI, 6.2%-16.9%)]. CONCLUSIONS: Among patients with fibrotic noncirrhotic NASH, metabolic surgery resulted in simultaneous NASH resolution and fibrosis improvement in half of patients.

IFSO Consensus on Definitions and Clinical Practice Guidelines for Obesity Management-an International Delphi Study.

INTRODUCTION: This survey of international experts in obesity management was conducted to achieve consensus on standardized definitions and to identify areas of consensus and non-consensus in metabolic bariatric surgery (MBS) to assist in an algorithm of clinical practice guidelines for the management of obesity. METHODS: A three-round Delphi survey with 136 statements was conducted by 43 experts in obesity management comprising 26 bariatric surgeons, 4 endoscopists, 8 endocrinologists, 2 nutritionists, 2 counsellors, an internist, and a pediatrician spanning six continents over a 2-day meeting in Hamburg, Germany. To reduce bias, voting was unanimous, and the statements were neither favorable nor unfavorable to the issue voted or evenly balanced between favorable and unfavorable. Consensus was defined as ≥ 70% inter-voter agreement. RESULTS: Consensus was reached on all 15 essential definitional and reporting statements, including initial suboptimal clinical response, baseline weight, recurrent weight gain, conversion, and revision surgery. Consensus was reached on 95/121 statements on the type of surgical procedures favoring Roux-en-Y gastric bypass, sleeve gastrectomy, and endoscopic sleeve gastroplasty. Moderate consensus was reached for sleeve gastrectomy single-anastomosis duodenoileostomy and none on the role of intra-gastric balloons. Consensus was reached for MBS in patients > 65 and < 18 years old, with a BMI > 50 kg/m2, and with various obesity-related complications such as type 2 diabetes, liver, and kidney disease. CONCLUSIONS: In this survey of 43 multi-disciplinary experts, consensus was reached on standardized definitions and reporting standards applicable to the whole medical community. An algorithm for treating patients with obesity was explored utilizing a thoughtful multimodal approach.

Impact of Bariatric Surgery on Left Ventricular Structure and Function.

BACKGROUND: Obesity leads to an increased risk of cardiovascular disease morbidity and death, including heart failure. Bariatric surgery has been proven to be the most effective long-term weight management treatment. This study investigated the changes in cardiac structure and function after bariatric surgery, including left ventricular global longitudinal strain. METHODS AND RESULTS: There were 398 consecutive patients who underwent bariatric surgery with pre- and postoperative transthoracic echocardiographic imaging at a US health system between 2004 and 2019. We compared cardiovascular risk factors and echocardiographic parameters between baseline and follow-up at least 6 months postoperatively. Along with decreases in weight postoperatively, there were significant improvements in cardiovascular risk factors, including reduction in systolic blood pressure levels from 132 mm Hg (25th-75th percentile: 120-148 mm Hg) to 127 mm Hg (115-140 mm Hg; P=0.003), glycated hemoglobin levels from 6.5% (5.9%-7.6%) to 5.7% (5.4%-6.3%; P<0.001), and low-density lipoprotein levels from 97 mg/dL (74-121 mg/dL) to 86 mg/dL (63-106 mg/dL; P<0.001). Left ventricular mass decreased from 205 g (165-261 g) to 190 g (151-236 g; P<0.001), left ventricular ejection fraction increased from 58% (55%-61%) to 60% (55%-64%; P<0.001), and left ventricular global longitudinal strain improved from -15.7% (-14.3% to -17.5%) to -18.6% (-16.0% to -20.3%; P<0.001) postoperatively. CONCLUSIONS: This study has shown the long-term impact of bariatric surgery on cardiac structure and function, with reductions in left ventricular mass and improvement in left ventricular global longitudinal strain. These findings support the cardiovascular benefits of bariatric surgery.

Diagnosis and management of post-bariatric surgery hypoglycemia.

INTRODUCTION: While bariatric surgery remains the most effective treatment for obesity that allows substantial weight loss with improvement and possibly remission of obesity-associated comorbidities, some postoperative complications may occur. Managing physicians need to be familiar with the common problems to ensure timely and effective management. Of these complications, postoperative hypoglycemia is an increasingly recognized complication of bariatric surgery that remains underreported and underdiagnosed. AREA COVERED: This article highlights the importance of identifying hypoglycemia in patients with a history of bariatric surgery, reviews pathophysiology and addresses available nutritional, pharmacological and surgical management options. Systemic evaluation including careful history taking, confirmation of hypoglycemia and biochemical assessment is essential to establish accurate diagnosis. Understanding the weight-dependent and weight-independent mechanisms of improved postoperative glycemic control can provide better insight into the causes of the exaggerated responses that lead to postoperative hypoglycemia. EXPERT OPINION: Management of post-operative hypoglycemia can be challenging and requires a multidisciplinary approach. While dietary modification is the mainstay of treatment for most patients, some patients may benefit from pharmacotherapy (e.g. GLP-1 receptor antagonist); Surgery (e.g. reversal of gastric bypass) is reserved for unresponsive severe cases. Additional research is needed to understand the underlying pathophysiology with a primary aim in optimizing diagnostics and treatment options.

Does one-anastomosis gastric bypass provide better outcomes than sleeve gastrectomy in patients with BMI greater than 50? A systematic review and meta-analysis.

In patients with BMI greater than 50, sleeve gastrectomy (SG) may not be adequate to treat obesity. To determine whether one-anastomosis gastric bypass (OAGB) can provide better outcomes compared with SG in patients with BMI greater than 50, a systematic review and meta-analysis was conducted, including a total of nine retrospective studies with a total of 2332 participants. There was a significant difference in the percentage of excess weight loss [weighted mean difference (WMD): 8.52; 95% CI: 5.81-11.22; P<0.001) and percentage of total weight loss (WMD: 6.65; 95% CI: 5.05-8.24; P<0.001). No significant differences were seen in operative time (WMD: 1.91; 95% CI: -11.24 to 15.07; P=0.77) and length of stay in hospital (WMD: -0.41; 95% CI: -1.18 to 0.37; P=0.30) between the two groups. There were no significant differences between OAGB with SG in Clavien-Dindo grades I-III [odds ratio (OR): 1.56; 95% CI: 0.80-3.05], or grade IV complications (OR: 0.72; 95% CI: 0.18-2.94). The meta-analysis on remission of type 2 diabetes indicated a comparable effect between SG and OAGB (OR: 0.77; 95% CI: 0.28-2.16). The OAGB group had a significantly higher rate of remission of hypertension compared with the SG group (OR: 1.63; 95% CI: 1.06-2.50). The findings of this meta-analysis suggest that the OAGB accomplished a higher percentage of total weight loss and percentage of excess weight loss at short-term and mid-term follow-up but, there was no major difference between the OAGB and SG operations in terms of perioperative outcomes, complications, and diabetes remission.

Mapping the Unseen: In Vivo CEST-MRI of Creatine Reveals Improved Cardiac Energetics in Subjects with Obesity Following Bariatric Surgery.

BACKGROUND: Obesity is associated with derangement of cardiac metabolism and the development of subclinical cardiovascular disease. This prospective study examined the impact of bariatric surgery on cardiac function and metabolism. METHODS: Subjects with obesity underwent cardiac magnetic resonance imaging (CMR) at Massachusetts General Hospital before and after bariatric surgery between 2019 and 2021. The imaging protocol included Cine for global cardiac function assessment and creatine chemical exchange saturation transfer (CEST) CMR for myocardial creatine mapping. RESULTS: Thirteen subjects were enrolled, and 6 subjects [mean BMI 40.5 ± 2.6] had completed the second CMR (i.e. post-surgery), with a median follow-up of 10 months. The median age was 46.5 years, 67% were female, and 16.67% had diabetes. Bariatric surgery led to significant weight loss, with achieved mean BMI of 31.0 ± 2.0. Additionally, bariatric surgery resulted in significant reduction in left ventricular (LV) mass, LV mass index, and epicardial adipose tissue (EAT) volume. This was accompanied by slight improvement in LV ejection fraction compared to baseline. Following bariatric surgery, there was a significant increase in creatine CEST contrast. Subjects with obesity had significantly lower CEST contrast compared to subjects with normal BMI (n = 10), but this contrast was normalized after the surgery, and statistically similar to non-obese cohort, indicating an improvement in myocardial energetics. CONCLUSIONS: CEST-CMR has the ability to identify and characterize myocardial metabolism in vivo non-invasively. These results demonstrate that in addition to reducing BMI, bariatric surgery may favorably affect cardiac function and metabolism.

Obesity-associated cancer risk reduction after metabolic surgery: insights from the SPLENDID study and the path forward.

Obesity incidence continues to rise globally along with obesity-associated conditions, which heavily burden individuals' quality of life and healthcare systems. Evidence regarding the power of metabolic and bariatric surgery to treat obesity has, fortunately, brought to light how substantial and sustained weight loss can mitigate adverse clinical outcomes of obesity and metabolic disease. Obesity-associated cancer has been an important focus of studies in recent decades to further elucidate what impact metabolic surgery could have on incidence of cancer and cancer-related mortality. The SPLENDID (Surgical Procedures and Long-term Effectiveness in Neoplastic Disease Incidence and Death) study is one of the recent large cohort studies that highlights the power of substantial weight loss and the long-term benefits to patients with obesity in preventing cancer. This review of SPLENDID aims to highlight both consistency of results with prior studies and new findings unexplored previously.

Best practice approach for redo-surgeries after sleeve gastrectomy, an expert's modified Delphi consensus.

BACKGROUND: Sleeve gastrectomy (SG) is the most common metabolic and bariatric surgical (MBS) procedure worldwide. Despite the desired effect of SG on weight loss and remission of obesity-associated medical problems, there are some concerns regarding the need to do revisional/conversional surgeries after SG. This study aims to make an algorithmic clinical approach based on an expert-modified Delphi consensus regarding redo-surgeries after SG, to give bariatric and metabolic surgeons a guideline that might help for the best clinical decision. METHODS: Forty-six recognized bariatric and metabolic surgeons from 25 different countries participated in this Delphi consensus study in two rounds to develop a consensus on redo-surgeries after SG. An agreement/disagreement ≥ 70.0% on statements was considered to indicate a consensus. RESULTS: Consensus was reached for 62 of 72 statements and experts did not achieve consensus on 10 statements after two rounds of online voting. Most of the experts believed that multi-disciplinary team evaluation should be done in all redo-procedures after SG and there should be at least 12 months of medical and supportive management before performing redo-surgeries after SG for insufficient weight loss, weight regain, and gastroesophageal reflux disease (GERD). Also, experts agreed that in case of symptomatic GERD in the presence of adequate weight loss, medical treatment for at least 1 to 2 years is an acceptable option and agreed that Roux-en Y gastric bypass is an appropriate option in this situation. There was disagreement consensus on efficacy of omentopexy in rotation and efficacy of fundoplication in the presence of a dilated fundus and GERD. CONCLUSION: Redo-surgeries after SG is still an important issue among bariatric and metabolic surgeons. The proper time and procedure selection for redo-surgery need careful considerations. Although multi-disciplinary team evaluation plays a key role to evaluate best options in these situations, an algorithmic clinical approach based on the expert's consensus as a guideline can help for the best clinical decision-making.

2022 American Society of Metabolic and Bariatric Surgery (ASMBS) and International Federation for the Surgery of Obesity and Metabolic Disorders (IFSO) Indications for Metabolic and Bariatric Surgery.

MAJOR UPDATES TO 1991 NATIONAL INSTITUTES OF HEALTH GUIDELINES FOR BARIATRIC SURGERY: Metabolic and bariatric surgery (MBS) is recommended for individuals with a body mass index (BMI) >35 kg/m2, regardless of presence, absence, or severity of co-morbidities.MBS should be considered for individuals with metabolic disease and BMI of 30-34.9 kg/m2.BMI thresholds should be adjusted in the Asian population such that a BMI >25 kg/m2 suggests clinical obesity, and individuals with BMI >27.5 kg/m2 should be offered MBS.Long-term results of MBS consistently demonstrate safety and efficacy.Appropriately selected children and adolescents should be considered for MBS.(Surg Obes Relat Dis 2022; https://doi.org/10.1016/j.soard.2022.08.013 ) © 2022 American Society for Metabolic and Bariatric Surgery.

How much narcotics are really needed after bariatric surgery: results of a prospective study.

BACKGROUND: To mitigate the opioid crisis, physicians are reevaluating opioid prescribing patterns. OBJECTIVES: To evaluate outcomes of maximal opioid reduction on top of an existing Enhanced Recovery after Surgery (ERAS) pathway in our The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program-accredited bariatric surgery program. SETTING: Academic tertiary care hospital, United States. METHODS: Patients undergoing primary bariatric operation were studied from July 2017 to April 2019, (standard ERAS cohort), and compared to patients from April 2019 to February 2021 (standard ERAS with Sparing Opioid Use Postoperatively protocol) (SOUP cohort). The primary endpoint was reduction of perioperative opioid use. RESULTS: Of 367 patients, 212 (57.8%) and 155 (42.2%) were in the ERAS and SOUP cohorts, respectively. Roux-en-Y gastric bypass was 48.6% (n = 103) versus 54.2% (n = 84) and sleeve gastrectomy was 51.4% (n = 109) versus 45.8% (n = 71) for ERAS versus SOUP, respectively (P = .29). The SOUP cohort of patients required a low median inpatient morphine equivalent dose of 4 mg [0-6.2]. The ERAS cohort was discharged on a higher morphine equivalent dose than the SOUP cohort at 186.7 mg ± 92.9 versus 37.6 ± 32.3 (P < .05), and median consumption of the standard 5 mg oxycodone tablet was 1.5 tablets [0-4]. The SOUP cohort patients rated their pain satisfaction score on a scale of 1 to 10 at 9.1 points (standard deviation ± 1.8). The SOUP cohort had a shorter length of stay (P < .05), with comparable readmission rates. CONCLUSIONS: An opioid-sparing protocol can be implemented after bariatric surgery with high overall satisfaction with pain control.

Bariatric surgery is as safe as other common operations: an analysis of the ACS-NSQIP.

BACKGROUND: Metabolic and Bariatric Surgery (MBS) is the most effective management for patients with obesity and weight-related medical conditions. Nonetheless, some primary care physicians (PCPs) and surgeons from other specialties are reluctant to refer patients for MBS due to safety concerns. OBJECTIVES: To compare the outcomes of patients who underwent MBS with those who underwent other common operations. SETTING: American College of Surgeons-National Surgical Quality Improvement Program (ACS-NSQIP). METHODS: Patients who underwent laparoscopic sleeve gastrectomy and Roux-en-Y gastric bypass (RYGB), classified as MBS, were compared to nine frequently performed procedures including hip arthroplasty and laparoscopic cholecystectomy, appendectomy, colectomy, hysterectomy, and hernia repairs, among others. A multivariable logistic regression was constructed to compare outcomes including readmission, reoperation, extended length of stay (ELOS) (>75th percentile or ≥3 days) and mortality. RESULTS: A total of 1.6 million patients were included, with 11.1% undergoing MBS. The odds of readmission were marginally lower in the cholecystectomy (adjusted odds ratio [aOR] = .88, 95% confidence interval (CI) [.85, .90]) and appendectomy (aOR = .88, 95% CI [.85, .90]) cohorts. Similarly, odds of ELOS were among the lowest, surpassed only by same-day procedures such as cholecystectomies and appendectomies. The MBS group had significantly low odds of mortality, comparable to safe anatomical procedures such as hernia repairs. Infectious and thrombotic complications were exceedingly rare and amongst the lowest after MBS. CONCLUSIONS: MBS demonstrates a remarkably promising safety profile and compares favorably to other common procedures in the short-term. PCPs and surgeons from other specialties can confidently refer patients for these low-risk, lifesaving operations.
