RESUMO
BACKGROUND & AIMS: The Primary Obesity Surgery Endoluminal (POSE) 2.0 procedure involves a novel pattern of full-thickness gastric body plications to shorten and narrow the stomach using durable suture anchor pairs. Our prospective, multicenter trial examined the safety, efficacy, durability, and physiologic effects of POSE 2.0 in adults with obesity. METHODS: Adults with obesity underwent POSE 2.0 at 3 centers. Primary outcomes were percent total body weight loss (%TBWL) and proportion of patients achieving >5% TBWL at 12 months. Secondary outcomes included change in obesity comorbidities, satiety, quality of life at 6 months, and durability of plications at 12 and 24 months. Subjects were followed for adverse events throughout the study duration. RESULTS: 44 patients (61% female; mean age, 45 ± 9.7 years; mean body mass index, 37 ± 2.1 kg/m2) were enrolled. This procedure used an average of 19 suture anchor pairs, with a mean duration of 37 ± 11 minutes, and was technically successful in all subjects. Mean %TBWL at 12 months was 15.7% ± 6.8%. At 12 months, %TBWL >5%, >10%, and >15% was achieved in 98%, 86%, and 58% of patients, respectively. Improvements in lipid profile, liver biochemistries, and hepatic steatosis were seen at 6 months. Improvements in hepatic steatosis persisted for 24 months in a subgroup of patients (P < .01). POSE 2.0 reduced maximum tolerated meal volume (P = .03) and was associated with increased fullness (P < .01) and improved eating behavior (P < .01) at 6 months. Impact of weight on quality-of-life questionnaire improved at 6 months (2.23 vs 1.23; P < .01). Repeat assessment at 24 months (n = 26) showed fully intact plications. No serious adverse events occurred. CONCLUSION: POSE 2.0 is an effective and durable endoscopic bariatric therapy which may influence physiologic pathways impacting satiety. Larger comparative studies are needed to further elucidate these initial findings. CLINICALTRIALS: gov Identifier: NCT03721731.

Background: Bariatric endoscopy has emerged for non-surgical treatment of obesity, providing a treatment option for weight loss and associated comorbidities. Outcomes of endoscopic sleeve gastroplasty (ESG) of 12 months have been published by our team and there is a need for longer follow-up period understanding the effects of ESG techniques. Aim: This report emphasises on weight loss pattern in follow-up time points and monitors the post-procedure improvement in comorbidities with minimum 4-year follow-up of patients undergoing ESG at a single academic centre in India. Subjects and Methods: This was a prospective cohort study. All procedures were performed by the same surgeon. Patients with a body mass index of >30 kg/m2 (or >27 with comorbidities) underwent ESG for treatment of obesity. Patients were systematically followed yearly after their procedure. Data collected on the primary outcome and secondary outcomes were analysed and presented. Results: 612 patients (69.3% female) with a mean age of 40.70 ± 12.66 years and mean body mass index of 34.30 ± 5.05 kg/m2 underwent ESG. Out of 612 patients, follow-up rates for a 1-2-3 and 4 years were 93.1%, 90.2%, 81.7% and 81.9%, respectively. The mean percentage total body weight loss was 18.19% (95% confidence interval [CI]: 17.72-18.57) and %EWL was 49.30% (95% CI: 48.91-49.68) with 90% of participants-maintaining a percentage of total weight loss of ≥5% and 70% of patients maintaining an EWL of ≥25% at 4 years, respectively. Resolution/improvement of comorbidities was 51.2% cases of T2DM, 65.8% cases of hypertension, 73.6% cases of dyslipidaemia and 89.9% remission were in obstructive sleep apnoea. No patient required an emergency intervention, and there was no mortality or significant morbidity. Conclusions: This study shows acceptable results with ESG at 4 years in our unit. Regular monitoring by a multidisciplinary nurtures weight loss, resolution or improvement of comorbidities and improvement of quality of life with low perioperative complications. There is a need for more reports with this approach to determine the amount and duration of weight loss outcome and medical intervention.
RESUMO
The intragastric balloon is a temporary and minimally invasive therapy for weight loss, currently being the main choice for mild obesity. As a space-occupying device, it reduces stomach capacity, resulting in decreased hunger and food intake. There are different balloon models, filled with liquid or air. The most used is the non-adjustable liquid-filled balloon, due to its lower rate of complications. The mechanism of action is multifactorial, involving physiological and neurohormonal changes. The device functions as an artificial bezoar, filling the stomach and leading to early satiety. In the Brazilian Intragastric Balloon Consensus Statement, there was a mean excess weight loss of 18.4%, showing effective weight loss and good safety profile. It is a valid option for overweight and obese patients unresponsive to clinical therapy or who are either not candidates for surgery or who do not wish to undergo a definitive procedure. Besides weight loss, recent studies have shown a positive effect on metabolic parameters. New devices have been developed, such as procedureless and adjustable balloons, with promising results.

BACKGROUND AND AIMS: Laparoscopic sleeve gastrectomy (LSG) facilitates significant and durable weight loss; however, weight recidivism and need for revisional surgery occur in a subset of patients. Reduction of a dilated LSG using the revisional endoscopic sleeve gastroplasty (R-ESG) approach is an appealing and minimally invasive alternative to surgical revision that is congruent with obesity as a chronic relapsing disease model. In this study, we examine the safety and efficacy of the technique in a large multicenter international cohort. METHODS: Prospectively collected data from 9 centers for 82 consecutive adults who underwent R-ESG for weight regain after LSG using the OverStitch device (Apollo Endosurgery, Austin, Tex, USA) from March 2014 to November 2019 were reviewed. Total body weight loss (TBWL) and adverse events were reported up to 12 months. Univariable logistic regression was used to identify predictors of response at 12 months. RESULTS: Eighty-two adults (92.7% female) experienced 27.9 ± 20.7 kg weight regain from post-LSG nadir weight, prompting R-ESG (mean age, 42.8 ± 10.4 years) at a mean weight of 128.2 ± 57.5 kg. Mean R-ESG procedure duration was 48.3 ± 20.5 minutes, and the median number of sutures used was 4 (interquartile range, 3-4). After R-ESG, TBWL (follow-up %) was 6.6% ± 3.2% at 1 month (81.7%), 10.6% ± 4.4% at 3 months (74.4%), 13.2% ± 10.1% at 6 months (63.4%), and 15.7% ± 7.6% at 12 months (51.2%). In a per-protocol analysis, ≥10% TBWL was achieved by 37 of 51 patients (72.5%) at 6 months and 34 of 42 patients (81.0%) at 12 months; ≥15% TBWL was achieved by 20 of 46 patients (43.5%) at 6 months and 22 of 42 patients (52.4%) at 12 months. Only 1 moderate adverse event occurred in the form of a narrowed gastroesophageal junction, which resolved after a single endoscopic dilation. CONCLUSIONS: R-ESG is a safe and effective means of facilitating weight loss for weight recidivism after LSG, with sustained results at 1 year. R-ESG should be considered before pursuing more-invasive surgical revisional options.

BACKGROUND AND AIMS: Endoscopic sleeve gastroplasty (ESG) has been shown to be effective for inducing weight loss. The efficacy of liraglutide, a glucagon-like peptide-1 agonist, to augment weight loss after ESG is unknown. This study aims to evaluate the efficacy of ESG and liraglutide (ESG-L) compared with ESG alone. METHODS: This was a retrospective study of prospectively collected data from patients undergoing ESG at 3 outpatient clinics in Brazil between November 2017 and July 2018. Liraglutide was offered to all patients 5 months after ESG. Patients who opted to take liraglutide (ESG-L) were matched 1:1 to patients who declined it (ESG). The primary outcome was percent total body weight loss (%TBWL), and percent excess weight loss (%EWL) 7 months after initiation of liraglutide (12 months after ESG). The secondary outcome was change in percent body fat 12 months after ESG. ESG technique and postprocedure follow-up were identical at all 3 sites. RESULTS: Propensity score matching yielded 26 matched pairs. Adjusted comparisons between the 2 groups showed that patients who opted to take liraglutide had a superior mean %TBWL 7 months after initiation of liraglutide (ESG-L) compared with those who declined it (ESG) (24.72% ± 2.12% vs 20.51% ± 1.68%, respectively; P < .001). ESG-L had a statistically greater reduction in percent body fat compared with ESG (7.85% ± 1.26% vs 10.54% ± 1.88%, respectively; P < .001) at 12 months. CONCLUSIONS: Addition of liraglutide at 5 months results in superior weight loss and improved efficacy as demonstrated by decreased body fat 12 months after ESG. Further studies are imperative to determine optimal dose, timing, and duration of liraglutide.

BACKGROUND & AIMS: Bariatric surgery is the most successful treatment for obesity. However, many patients avoid surgery due to its perceived invasive nature and fear of complications. Endoscopic sleeve gastroplasty (ESG) is a seemingly less invasive option for patients with obesity. We performed a systematic review and meta-analysis to evaluate the efficacy and safety of ESG in adults. METHODS: We searched MEDLINE, Embase, Web of Science, and Cochrane Library through July 2019. Investigated outcomes included the percent total body weight loss (TBWL), body mass index reduction, percent excess weight loss (EWL), and adverse events. RESULTS: We extracted data from 8 original studies, published from 2016 through 2019, which included a total of 1772 patients. At 6 months, mean TBWL was 15.1% (95% CI, 14.3-16.0), mean decrease in body mass index was 5.65 kg/m2 (95% CI, 5.07-6.22), and mean excess weight loss was 57.7% (95% CI, 52.0-63.4). Weight loss was sustained at 12 months and 18-24 months with a TBWL of 16.5% (95% CI, 15.2-17.8) and 17.2% (95% CI, 14.6-19.7), respectively. The pooled post-ESG rate of severe adverse events was 2.2% (95% CI, 1.6%-3.1%), including pain or nausea requiring hospitalization (n = 18, 1.08%), upper gastrointestinal bleeding (n=9, 0.56%), and peri-gastric leak or fluid collection (n = 8, 0.48%). CONCLUSIONS: In a systematic review and meta-analysis, we found ESG to produce clinically significant weight loss that was reproducible among independent centers and to have a low rate of severe adverse events. ESG appears to be an effective intervention for patients with obesity, although comparative studies and randomized controlled trials are necessary. PROSPERO Identifier: CRD42019121921.

BACKGROUND: Endoscopic sleeve gastroplasty (ESG) is an option for patients with Class I and II obesity or patients who refuse to undergo a laparoscopic bariatric surgery. The aims of this study are as follows: (1) to demonstrate a short-term outcome after primary ESG and (2) to compare the effectiveness of weight loss between Class I and Class II obesity patients. METHODS: Patients undergoing ESG at four bariatric centers in Brazil between April 1, 2017 and December 31, 2018 were prospectively enrolled in the study (BMI 30.0-39.9 kg/m2). ESG was performed using Overstitch (Apollo Endosurgery, Austin, TX). Descriptive analysis, t test, Chi-square test, and Mann-Whitney test were used to present the results. RESULTS: A total of 233 patients underwent primary ESG. The mean age and BMI of the patients were 41.1 years and 34.7 kg/m2, respectively. Following ESG, the mean percentage of total weight loss (TWL) was 17.1% at 6 months and 19.7% at 12 months. Percentage of excess BMI loss (EBMIL) was 47.3% at 6 months and 54.8% at 12 months after ESG. The mean EBMIL was significantly greater among patients with Class I obesity than those with Class II obesity at 6 (51.1% vs. 43.7%) and 12 months (60.2% vs. 49.2%). One patient experienced bleeding during the procedure that was managed with sclerotherapy. CONCLUSION: Short-term results suggest that ESG is a safe and effective option for patients with Class I and II obesity.

BACKGROUND AND AIM: Endoscopic sleeve gastroplasty (ESG) is gaining acceptance as a non-surgical option for the treatment of obesity. However, its role is still not consolidated for all populations and the ideal indications are yet to be determined. We aimed to study the efficacy and safety of ESG in Indian patients. METHODS: We conducted a single-center retrospective study of obese patients who underwent consecutive ESG at our tertiary care center. Data on weight loss and adverse events at 1, 3, 6, and 12 months were collected and analyzed. RESULTS: Fifty-three patients underwent ESG from March 2017 to October 2018. Eighty one percent of patients were female (43/53). Mean baseline age and body mass index were 40.54â±â13.79 years and 34.78â±â5.20 kg/m2 , respectively. Mean duration of procedure was 68.96 ± 11.19 min. Immediate postoperative complications included mainly epigastric pain (45.2%) and nausea (22.6%) but there was no serious adverse event. Average percentage of total weight loss (%TWL) was 8.26%, 11.96%, 14.25%, and 19.94% at 1, 3, 6, and 12 months, respectively. Eighty-eight percent of patients achieved >15% TWL at 12 months. Younger patients (<30 years old) and female patients had greater %TWL at 12 months (P = 0.01 and P = 0.021, respectively). Last 18 procedures were significantly faster than the first 35 cases (P = 0.01). CONCLUSIONS: Endoscopic sleeve gastroplasty is effective and safe at promoting weight loss in the Indian population. Young age and female gender are related to better outcomes.

BACKGROUND AND AIMS: Many patients who undergo bariatric surgery will experience weight regain and effective strategies are needed to help these patients. A dilated gastrojejunal anastomosis (GJA) has been associated with weight recidivism after Roux-en-Y gastric bypass surgery (RYGB). Endoscopic transoral outlet reduction (TORe) with a full thickness endoscopic suturing device (Overstitch, Apollo Endosurgery, Austin, TX) is a minimally invasive therapeutic option. The primary aim of this project was to examine the safety and long-term efficacy data from three bariatric surgery centers and to conduct a systematic review and meta-analysis of the existing literature. METHODS: Patients who underwent TORe with the Overstitch device from Jan 2013 to Nov 2016 at 3 participating bariatric surgery centers were included in the multicenter analysis. For the systematic review and meta-analysis, a comprehensive search of multiple English databases was conducted. Random effects model was used. RESULTS: 130 consecutive patients across three centers underwent TORe with an endolumenal suturing device. These patients (mean age 47; mean BMI 36.8) had experienced 24.6% weight regain from nadir weight after RYGB. Average weight lost at 6, 12, and 18 months after TORe was 9.31 ± 6.7 kg (N = 84), 7.75 ± 8.4 kg (N = 70), 8 ± 8.8 kg (N = 46) (p < 0.01 for all three time points), respectively. The meta-analysis included 330 patients. The pooled weight lost at 12 months was 8.4 kg (95% CI 6.5-10.3) with no significant heterogeneity across included studies (p = 0.07). Overall, 14% of patients experienced nausea, 18% had pain and 8% required a repeat EGD. No serious adverse events reported. CONCLUSION: When implemented as part of a multidisciplinary intervention, TORe using endolumenal suturing is safe, reproducible, and effective approach to manage weight recidivism after RYGB and should be utilized early in the management algorithm of these patients.

BACKGROUND AND STUDY AIMS: Ring complications after a banded Roux-en-Y gastric bypass (RYGB) are usually managed surgically. The aim of this study was to analyze the safety and effectiveness of endoscopic removal of noneroded rings after banded-RYGB, by inducing intragastric erosion of the ring using a self-expandable plastic stent (SEPS). PATIENTS AND METHODS: A total of 41 patients with banded RYGB who had noneroded rings and food intolerance were prospectively enrolled. Patients were treated with endoscopic SEPS placement and ring removal. Data from time of stenting, resolution of symptoms, need for endoscopic dilation, and complications were recorded. RESULTS: Successful ring removal was possible in all patients. In 21 cases, the SEPS induced complete erosion, and in 17 cases the ring was removed a month later because of incomplete erosion at the time of SEPS removal. Nine patients (22.0â%) needed endoscopic dilation after stent removal in order to treat fibrotic strictures. Food tolerance was observed in 32 patients (78.0â%) after the procedure. No patient needed surgery and there were no deaths. CONCLUSIONS: Endoscopic removal of the ring using SEPS appeared to be safe and effective after a banded RYGB.

BACKGROUND: Gastric fistula after bariatric surgery has high morbi-mortality, and treatment is a challenge due to persistent abscess and/or distal stenosis. The present study evaluated the efficacy and safety of stricturotomy/internal drainage, a novel endoscopic procedure that can avoid re-operation and allow early oral feeding. METHODS: This prospective, non-randomized study, with no control or sham group, included 27 patients (74.07% were female), approved by the local IRB, who underwent the following bariatric surgeries: Roux-en-Y gastric bypass (RYGB; n = 14, 51.85%), laparoscopic sleeve gastrectomy (LSG; n = 9, 33.33%) and duodenal switch (DS; n = 4, 14.81%). The patients presented with gastric fistulas which were treated by internal drainage/stricturotomy. The mean patient age was 42.67 years, and the mean pre-operative BMI was 40.69 kg/m(2). Balloon dilation was performed if distal stenosis and/or axis deviation was present. The first endoscopic procedure was applied on the 15th day after RYGB and the 30th day after LSG and DS. RESULTS: All patients presented with His angle fistula. Eight patients (57.1%) had stenosis of the anastomosis after RYGB and were treated with balloon dilatation (20 mm). The patients submitted to LSG and DS had stenosis at the angularis incisure and were treated with achalasia balloon dilation (30 mm). The number of endoscopic sessions for stricturotomy ranged from 1 to 6. Two patients experienced bleeding after dilation, and one had perforation. The mean time to achieve fistula closure was 18.11 days (range, 1-72 days) without mortality. All the fistulas closed. CONCLUSIONS: This novel endoscopic procedure is safe, feasible, and effective, avoiding re-operation, allowing early oral feeding and discharge.

BACKGROUND: Obesity is a significant public health issue; new therapies and pharmaceutical approaches to weight management are needed. OBJECTIVE: This study assesses weight reduction efficacy in the novel swallow balloon procedure and semaglutide, both promising non-surgical and pharmaceutical options, addressing obesity's critical public health challenge. METHODS: This was a computer-generated, blocked randomisation, double-blind, single-centre study. Fifty-seven participants were assigned to swallow balloon therapy group I (with semaglutide), and 58 were assigned to swallow balloon therapy group II (without semaglutide). All treatment doses were orally administered once daily (3 mg for the 1st month, 7 mg for the 2nd month, and 14 mg for the 3rd and 4th months after the placement of the swallow balloon). All the data were statistically analysed. RESULTS: The groups were highly well-matched. The %TWL in group I was 7.9%, 12.5%, 15.2%, and 17.6% and in group II was 6.1%, 10.5%, 12.8%, and 13.7% at 1, 2, 3, and 4 months, respectively. The most common adverse events (AEs) were nausea and vomiting, observed within the week. The resolution of T2DM, HTN, and OSA was 64.7% vs 55.5%, 64.3% vs 58.8%, and 72.0 vs 57.8% in groups I vs II, respectively. QoL significantly improved 4 months postoperatively in both groups. No major late complications occurred in either of the groups. CONCLUSION: The study supports the efficacy of swallow balloon therapy combined with semaglutide oral formulation in promoting weight loss and improving comorbid conditions. The findings highlight the potential of this combined approach in managing obesity and its associated health issues.

PURPOSE OF REVIEW: The approval of resmetirom brings great hope to patients with metabolic dysfunction-associated steatohepatitis (MASH). The purpose of this review is to explore its impact on the global health environment. The implementation of multidisciplinary management MASH is proposed. RECENT FINDINGS: Resmetirom has benefits in the treatment of MASH, and its safety and effectiveness have been studied. The adverse events (AEs) need to be noticed. To improve patient outcomes, a multimodal approach with medication such as resmetirom, combined with metabolic and bariatric surgery (MBS) and lifestyle interventions can be conducted. MASH, a liver disease linked with obesity, is a challenging global healthcare burden compounded by the absence of any approved pharmacotherapy. The recent conditional approval by the Food and Drug Administration (FDA) in the United States of resmetirom, an oral, liver-directed, thyroid hormone receptor beta-selective agonist, marks a significant milestone, offering a treatment option for adults with non-cirrhotic MASH and who have moderate to advanced liver fibrosis. This narrative review discusses the efficacy and safety of resmetirom and its role in the therapeutic landscape of MASH treatment. Despite the promising hepatoprotective effect of resmetirom on histological liver endpoints, its use need further research, particularly regarding ethnic differences, effectiveness and cost-effectiveness, production scalability, social acceptance and accessibility. In addition, integrating resmetirom with other multidisciplinary therapeutic approaches, including lifestyle changes and MBS, might further improve clinical liver-related and cardiometabolic outcomes of individuals with MASH. This review highlights the importance of a comprehensive treatment strategy, supporting continued innovation and collaborative research to refine treatment guidelines and consensus for managing MASH, thereby improving clinical patient outcomes in the growing global epidemic of MASH. Studies done to date have been relatively short and ongoing, the course of the disease is highly variable, the conditions of various patients vary, and given this complex clinical phenotype, it may take many years of clinical trials to show long-term benefits.
RESUMO
PURPOSE: There is a lack of evidence for treatment of some conditions including complication management, suboptimal initial weight loss, recurrent weight gain, or worsening of a significant obesity complication after one anastomosis gastric bypass (OAGB). This study was designed to respond to the existing lack of agreement and to provide a valuable resource for clinicians by employing an expert-modified Delphi consensus method. METHODS: Forty-eight recognized bariatric surgeons from 28 countries participated in the modified Delphi consensus to vote on 64 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. RESULTS: A consensus was achieved for 46 statements. For recurrent weight gain or worsening of a significant obesity complication after OAGB, more than 85% of experts reached a consensus that elongation of the biliopancreatic limb (BPL) is an acceptable option and the total bowel length measurement is mandatory during BPL elongation to preserve at least 300-400 cm of common channel limb length to avoid nutritional deficiencies. Also, more than 85% of experts reached a consensus on conversion to Roux-en-Y gastric bypass (RYGB) with or without pouch downsizing as an acceptable option for the treatment of persistent bile reflux after OAGB and recommend detecting and repairing any size of hiatal hernia during conversion to RYGB. CONCLUSION: While the experts reached a consensus on several aspects regarding revision/conversion surgeries after OAGB, there are still lingering areas of disagreement. This highlights the importance of conducting further studies in the future to address these unresolved issues.

PURPOSE: With the global epidemic of obesity, the importance of metabolic and bariatric surgery (MBS) is greater than ever before. Performing these surgeries requires academic training and the completion of a dedicated fellowship training program. This study aimed to develop guidelines based on expert consensus using a modified Delphi method to create the criteria for metabolic and bariatric surgeons that must be mastered before obtaining privileges to perform MBS. METHODS: Eighty-nine recognized MBS surgeons from 42 countries participated in the Modified Delphi consensus to vote on 30 statements in two rounds. An agreement/disagreement among ≥ 70.0% of the experts was regarded to indicate a consensus. RESULTS: Consensus was reached on 29 out of 30 statements. Most experts agreed that before getting privileges to perform MBS, surgeons must hold a general surgery degree and complete or have completed a dedicated fellowship training program. The experts agreed that the learning curves for the various operative procedures are approximately 25-50 operations for the LSG, 50-75 for the OAGB, and 75-100 for the RYGB. 93.1% of experts agreed that MBS surgeons should diligently record patients' data in their National or Global database. CONCLUSION: MBS surgeons should have a degree in general surgery and have been enrolled in a dedicated fellowship training program with a structured curriculum. The learning curve of MBS procedures is procedure dependent. MBS surgeons must demonstrate proficiency in managing postoperative complications, collaborate within a multidisciplinary team, commit to a minimum 2-year patient follow-up, and actively engage in national and international MBS societies.
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: This study performed a meta-analysis to compare the safety and efficacy of argon plasma coagulation (APC) concerning suture (SUT) and surgery (SUR). METHODS: The One-Way tests were applied, with p <0.05 significant. The value of R2 was analyzed (heterogeneity), and the risk of bias of articles was evaluated. RESULTS: A total of 34 studies were found, eight about APC, twenty about SUT, and six about SUR. For the percentage of Weight Loss Regained (%WLR), the means for APC, SUT, and SUR were 19.39 ± 10.94, 26.06 ± 16.71, and 17.05 ± 9.85, and for success rate (%SR), the means were 89.75 ± 16.75, 86.80 ± 11.44, and 76.00 ± 21.57, respectively with p >0.05, with R2 ≥ 50%. CONCLUSION: The APC proved to be efficient and safe like the other techniques.
