RESUMO
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for the Surgery of Obesity and Metabolic Disorders (IFSO) issued new guidelines on the indications for MBS, which have superseded the previous 1991 National Institutes of Health guidelines.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.

BACKGROUND: Vertical sleeve gastrectomy is the most performed bariatric operation in the US; however, a significant number of patients suffer from persistent or new-onset reflux. No consensus for objective preoperative evaluation in these patients exists. We compared capsule-based pH testing vs GERD symptom scoring to determine extent of preoperative GERD to aid in procedure selection for bariatric surgery. STUDY DESIGN: An IRB-approved retrospective review of consecutive patients at a single institution was performed from April 2021 to December 2022. During initial consultation for bariatric surgery, a validated GERD symptom subjective survey was administered. All patients demonstrating interest in sleeve gastrectomy or had a history of reflux underwent upper endoscopy with capsule-based pH testing. RESULTS: Sixty-two patients underwent preoperative endoscopy with capsule-based pH testing and completed GERD symptom assessment survey(s). Median BMI was 43.4 kg/m 2 and 66.1% of patients were not taking a proton-pump inhibitor before performance of pH testing. There was negligible linear association between the objective DeMeester score obtained by capsule-based pH probe and GERD symptom survey scores. Median GERD symptom survey scores did not differ between patients with and without a diagnosis of GERD based on pH testing (all p values >0.11). CONCLUSIONS: An objective method for identifying severe GERD in the preoperative assessment may aid in the decision tree for procedure selection and informed consent process. Patients with significant preoperative GERD may be at higher risk for future GERD-related sleeve complications. Capsule-based pH testing may prove to be superior to subjective symptom scoring systems in this patient population.

BACKGROUND: The American Society of Metabolic and Bariatric Surgeons (ASMBS) Leadership Academy is conducted at the ASMBS Weekend to prepare surgeons for practice, while in their fellowship. OBJECTIVES: The aim of this analysis is to gather the views of current fellows in training on issues regarding practice patterns and career development. SETTING: Survey at ASMBS Fellows Leadership Academy. METHODS: An online survey was conducted at the last 2 ASMBS Leadership Academy Meetings at the ASMBS Weekend. There were 14 questions. There were 61 respondents. Twenty-three respondents had incomplete surveys and were not included in the final analysis. There were 24 fellows surveyed at the Leadership Academy in November 2022, in San Antonio, TX and 37 in January 2022, in Las Vegas, NV. RESULTS: Fifty-eight percent of attendees were interviewing for employment after their fellowship with 3.64% already employed. Eighteen percent had employment secured upon completion of their fellowship. Of the academic fellows, 29.1% believe that private practice will no longer exist in 2030 and 10.9% of attendees believe that we will have Medicare for all by 2030. Fellows in academic programs ranked their fellowship as either "best decision of my life" or "great" (96.4%) and 3.6% ranked it as "useless (not good/not bad)." Ninety-three percent of attendees said they would do a bariatric fellowship again. Of those that said they would not, all were from a robotic fellowship program. Of those that would do a bariatric fellowship again, 80% stated they would do so at the same institution. CONCLUSIONS: The fellows that attended the ASMBS Leadership Academy overall were very pleased with their fellowship experience, and most would choose to do a MIS/bariatric fellowship again.

Bariatric surgeries are often complicated by de-novo gastroesophageal reflux disease (GERD) or worsening of pre-existing GERD. The growing rates of obesity and bariatric surgeries worldwide are paralleled by an increase in the number of patients requiring post-surgical GERD evaluation. However, there is currently no standardized approach for the assessment of GERD in these patients. In this review, we delineate the relationship between GERD and the most common bariatric surgeries: sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB), with a focus on pathophysiology, objective assessment, and underlying anatomical and motility disturbances. We suggest a stepwise algorithm to help diagnose GERD after SG and RYGB, determine the underlying cause, and guide the management and treatment.
RESUMO
BACKGROUND: COVID-19 has disrupted life and put a spotlight on obesity as a risk factor for severe COVID-19 outcomes. Five years ago, we performed a survey exploring ways Americans view obesity and its treatment. We repeated the survey in the COVID-19 era to explore the impact of this once-in-a-century public health crisis on public perception and behavior surrounding obesity. OBJECTIVE: To explore if America's views on obesity have changed after more than 2 years of living through COVID-19. SETTING: The national survey was conducted by the National Opinion Research Center (NORC) from December 10 to 28, 2021. METHODS: We revisited some of the questions posed in a survey 5 years ago and added questions asking whether COVID-19 has changed views on obesity. We surveyed 1714 Americans sampled from a probability-based, nationally representative panel. Responses of Americans to questions about obesity were compared with the same or similar questions asked 5 years ago. RESULTS: COVID-19 has led to a change in how Americans view risks of obesity and benefits of treatment. Nearly one third (29%) of Americans became more worried about having obesity, and this is more pervasive among Black and Hispanic Americans (45%). This heightened concern led an estimated 28 million people to explore treatments not considered before the pandemic, including 6.4 million who thought about bariatric surgery or taking prescription obesity drugs. CONCLUSIONS: COVID-19 may have heightened Americans' worry about obesity. This may present an opportunity for conversations about treatments, including metabolic surgery.

Gastroesophageal reflux disease (GERD) is a common condition that is on the rise. Obesity is one risk factor that has increased in parallel with the rise of GERD. Typical symptoms include heartburn, regurgitation, dysphagia, cough, and chest pain. Patients with typical symptoms are empirically treated with proton pump inhibitors (PPIs). If the diagnosis is not clear, further evaluation is performed with endoscopy, pH monitoring, and esophageal manometry. Untreated GERD increases the risk of esophagitis, esophageal stricture, Barrett's esophagus, and esophageal adenocarcinoma. Treatment begins with lifestyle modification and medical therapy. If these fail, surgical and endoscopic surgical techniques are available, to provide treatment, symptom relief, and reduce long-term PPI use.

BACKGROUND: There is no evidence that insurance-mandated weight loss before bariatric surgery affects outcomes. OBJECTIVE: This retrospective study evaluated the relationship between insurance-mandated weight management program (WMP) completion before primary bariatric surgery and postoperative outcomes. SETTING: Suburban academic medical center. METHODS: Patients who underwent laparoscopic Roux-en-Y gastric bypass (LRYGB, n = 572) or sleeve gastrectomy (SG, n = 484) from 2014 to 2019 were dichotomized to presence (LRYGB n = 431, SG n = 348) or absence (LRYGB n = 141, SG n = 136) of insurance-mandated WMP completion. Primary endpoints included follow-up rate, percent total weight loss (%TWL), and percent excess weight loss (%EWL) through 60 months after surgery. The Mann-Whitney U test compared between-group means with significance at P < .05. RESULTS: Follow-up rate, %TWL, and %EWL were not different (P = NS) up to 60 months postoperation between groups for either surgery. Both LRYGB and SG patients without WMP completion maintained greater %TWL (LRYGB: 34.4 ± 11.1% versus 29.8 ± 11.0%, P = .159; SG: 21.4 ± 10.0% versus 18.2 ± 10.5%, P = .456) and %EWL (LRYGB: 71.3 ± 26.3% versus 67.6 ± 26.5%, P = .618; SG: 49.2 ± 18.8% versus 47.5 ± 28.8%, P = .753) at 36 months after surgery. Secondarily, duration of time to get to surgery was significantly greater among yes-WMP patients (LRYGB: 178 days versus 121 days, P < .001; SG: 169 days versus 95 days, P < .001). CONCLUSION: Insurance-mandated WMP completion before bariatric surgery delays patient access to surgery without improving postoperative weight loss potential and must be abandoned.

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.

BACKGROUND: Hiatal hernias are a common finding in patients who undergo bariatric surgery with an incidence of about 20% of all bariatric patients. Controversy exists on the utility of a biosynthetic tissue matrix (BTM) usage in combination with crural repair. This study was designed to explore the safety and benefits of the use of a BTM during concomitant hiatal hernia repair with bariatric surgical procedures. METHODS: This was a retrospective chart review of bariatric surgical patients who underwent a concomitant hiatal hernia repair at a single practice at a tertiary academic medical center from January 2014 to February 2019. RESULTS: A total of 420 patients were reviewed. Hiatal BTM reinforcement, recurrence, and postoperative proton pump inhibitor use were reported by type of operation. Recurrence was higher in gastric bypass patients who underwent hiatal hernia repair with suture cruroplasty alone vs. those who also underwent hiatal BTM reinforcement (7.1% vs. 3.7%, P = .52) and significantly higher in gastric sleeve patients who underwent hiatal hernia repair with suture cruroplasty alone vs. those who also underwent hiatal BTM reinforcement (7.1% vs. .5%, P = .01). No patient required reoperation for hiatal hernia recurrence. DISCUSSION: Performing Roux-en-Y gastric bypass or vertical sleeve gastrectomy with concomitant hiatal hernia repair is safe and durable. Employing crural reinforcement with BTM may be of benefit in reducing recurrence rates of hiatal hernia, particularly in sleeve gastrectomy patients.

BACKGOUND: The purpose of our study was to evaluate the use of minimally invasive Marshmallow Swallow Study (MSS) as a preoperative screening technique for patients and correlate marshmallow results with High Resolution Manometry (HRM) results and post-operative dysphagia following antireflux surgery. METHODS: A retrospective electronic chart review of data on 61 adult patients undergoing MSS was completed. Patients were included if they completed the MSS as well as: HRM and/or antireflux surgery. RESULTS: Sixty-one patients completed MSS. Of the 37 patients that completed HRM, 27 had abnormal results. 23 of these 27 patients who had abnormal results also failed MSS. The NPV for a failure on the MSS and abnormal HRM results is 0.767(p-value = 0.360). The PPV for a pass on the MSS and no post-operative dysphagia is 0.833 (p-value = 0.656). CONCLUSIONS: MSS is an effective screening tool for ruling out major esophageal motility disorders and can prevent need for invasive HRM.

BACKGROUND: Patients suspected of syncope frequently undergo laboratory and imaging studies to determine the etiology of the syncope. Variability exists in these workups across institutions. The purpose of this study was to evaluate the utilization and diagnostic yield of these workups and the patient characteristics associated with syncopal falls. METHODS: A multi-institutional retrospective review was performed on adult patients admitted after a fall between 1/2017-12/2018. Syncopal falls were compared to non-syncopal falls. RESULTS: 4478 patients were included. There were 795 (18%) patients with a syncopal fall. Electrocardiogram, troponin, echocardiogram, CT angiography (CTA), and carotid ultrasound were more frequently tested in syncope patients compared to non-syncope patients. Syncope patients had higher rates of positive telemetry/Holter monitoring, CTAs, and electroencephalograms. CONCLUSION: Patients who sustain syncopal falls frequently undergo diagnostic testing without a higher yield to determine the etiology of syncope.
