Abstract
The escalating obesity pandemic and its comorbidities necessitate adaptable and versatile treatment strategies. Endobariatric and metabolic therapies (EBMTs) can be strategically employed in a multipronged approach to obesity management, analogous to the way chess systems are employed to seize opportunities and thwart threats. In this review, we explore the spectrum of established and developing EBMTs, examining their efficacy in weight loss and metabolic improvement and their importance for a tailored, patient-centric approach. The complexity of obesity management mirrors the intricate nature of a chess game, with an array of tactics and strategies available to address the opponent's moves. Similarly, the bariatric endoscopist employs a range of EBMTs to alter the gastrointestinal tract landscape, targeting critical anatomical regions to modify physiological reactions to food consumption and nutrient assimilation. Gastric-focused EBMTs aim to reduce stomach capacity and induce satiety. Intestinal-focused EBMTs target hormonal regulation and nutrient absorption to improve metabolic profiles. EBMTs offer unique advantages of reversibility, adjustability and minimal invasiveness, allowing them to be used as primary treatments, adjuncts to pharmacotherapy or tools to address post-bariatric surgery weight recidivism. However, sub-optimal adoption of EBMTs due to lack of awareness, perceived costs and limited training opportunities hinders their integration into standard obesity management practices. By strategically integrating EBMTs into the broader landscape of obesity care, leveraging their unique advantages to enhance outcomes, clinicians can offer a more dynamic and personalized treatment paradigm. This approach, akin to employing chess systems to adapt to evolving challenges, allows for a comprehensive, patient-centric management of obesity as a chronic, complex and relapsing disease.

Berardo A, Polese L, Carniel EL, Toniolo I. How does sutures pattern influence stomach motility after endoscopic sleeve gastroplasty? A computational study. Updates Surg 2024:10.1007/s13304-024-01917-0. [PMID: 38954375 DOI: 10.1007/s13304-024-01917-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Accepted: 06/18/2024] [Indexed: 07/04/2024]
Abstract
The relatively recent adoption of Endoscopic Sleeve Gastroplasty (ESG) amongst obese patients has gained approval within the surgical community due to its notable benefits, including significant weight loss, safety, feasibility, repeatability, and potential reversibility. However, despite its promising clinical outcomes and reduced invasiveness, there is still a lack of standardised procedures for performing ESG. Multiple suture patterns and stitching methods have been proposed over time, yet rational tools to quantify and compare their effects on gastric tissues are absent. To address this gap, this study proposed a computational approach. The research involved a case study analyzing three distinct suture patterns (C-shaped, U-shaped and Z-shaped) using a patient-specific computational stomach model generated from magnetic resonance imaging. Simulations mimicked food intake by placing wire features in the intragastric cavity to replicate sutures, followed by applying a linearly increasing internal pressure up to 15 mmHg. The outcomes facilitated comparisons between suture configurations based on pressure-volume behaviours and the distribution of maximum stress on biological tissues, revealing the U-shaped as the more effective in terms of volume reduction, even if with reduced elongation strains and increased tissues stresses, whereas the Z-shaped is responsible of the greatest stomach shortness after ESG. In summary, computational biomechanics methods serve as potent tools in clinical and surgical settings, offering insights into aspects that are challenging to explore in vivo, such as tissue elongation and stress. These methods allow for mechanical comparisons between different configurations, although they might not encompass crucial clinical outcomes.

Abstract
PURPOSE Global obesity rates have surged, necessitating effective interventions beyond traditional bariatric and metabolic surgery (BMS). Endoscopic Sleeve Gastroplasty (ESG) has emerged as a minimally invasive alternative, addressing limitations of eligibility criteria and patient reluctance associated with BMS. This study aims to present a 3-year experience with ESG, focusing on its mid-term efficacy in weight loss. MATERIALS AND METHODS A retrospective, single-center study included 143 consecutive ESG patients (BMI > 30 kg/m2 or > 25 kg/m2 with obesity associated-diseases) from February 2019 to March 2023. Data on demographics, comorbidities, operative details, and follow-up outcomes were collected. The primary outcome was %TWL ≥ 15% at 12 months. Secondary outcomes were an optimal clinical response (OCR) at 24 and 36 months defined by %TWL ≥ 10% or %EWL ≥ 25%. RESULTS ESG demonstrated a mean %TWL of 14.37% at 12 months, aligning with previous studies. Early postoperative complications were minimal (2.1%), with no mortality. Follow-up revealed a peak in weight loss at 9 months, but mid-term OCR was achieved in 41.2% at 3 years. The learning curve showed efficiency improvements after 26 procedures. CONCLUSION ESG proves effective at one year, with a %TWL of 14.37%. However, mid-term efficacy beyond 12 months remains challenging, raising questions about the durability of weight loss. Despite a low complication rate, strategies for maintaining a long-term OCR, including potential repeat ESG, warrant further investigation.

COMPUTER METHODS AND PROGRAMS IN BIOMEDICINE 2024; 243:107889. [PMID: 37944398 DOI: 10.1016/j.cmpb.2023.107889] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Revised: 10/25/2023] [Accepted: 10/25/2023] [Indexed: 11/12/2023]
Abstract
BACKGROUND AND OBJECTIVES Within the framework of computational biomechanics, finite element models of the gastric district could be seen as a potential clinical tool not only to study the effects apported by bariatric surgery, but also to compare different surgical techniques such as the new emerging Endoscopic Sleeve Gastroplasty (ESG) with respect to well-established ones (such as the Laparoscopic Sleeve Gastrectomy, LSG). METHODS This work realized a fully computational comparison between the outcomes obtained from 10 patient-specific stomach models, which were used to simulate ESG, and the complementary results obtained from models representing the post-LSG of the same subjects. Specifically, once the ESG was simulated, a mechanical stimulus was applied by increasing an intragastric pressure up to a maximum of 5 kPa, in order to replicate the process of food intake, as well as for post-LSG models. RESULTS Results revealed non negligible differences between the techniques also within the same subject. In particular, not only LSG could lead to a greater reduction in the stomach volume (about 77 % at baseline, which is strictly linked to weight loss), but also influence the gastric distension (12 % less than pre-operative models). On the contrary, if ESG would be performed, a more similar pre-operative mechanical stimulation of the gastric walls may be seen (difference of about 1 %), thus preserving the mechanosensation, but the detriment of the volume reduction (about 56 % at baseline, and even decreases with increasing pressure). Moreover, since results suggested ESG may be more influenced by the pre-operative gastric cavity than LSG, a predictive model was proposed to support the surgical planning and the estimation of the volume reduction after ESG. CONCLUSIONS ESG and LSG have substantial differences in their protocols and post-surgical effects. This work pointed out that variations between the two procedures may be observed also from a computational point of view, especially when including patient-specific geometries. These insights support gastric modelling as a valuable tool to evaluate, design and critically compare emerging bariatric surgical procedures, not only from empirical aspects and clinical outcomes, but also from a mechanical point of view.

Abstract
This systematic review and meta-analysis aimed to determine the short- and medium-term weight loss outcomes and comorbidity resolution following endoscopic sleeve gastroplasty. Our search identified 35 relevant studies containing data from 7525 patients. Overall, pooled short-term (12 months) total weight loss (TWL) was 16.2% (95% CI 13.1-19.4%) in 23 studies (n = 5659). Pooled medium-term TWL was 15.4% (95% CI 13.7-17.2%) in 10 studies (n = 4040). Diabetes resolution was 55.4% (95% CI 46-64%), hypertension resolution was 62.8% (95% CI 43-82%), dyslipidaemia resolution was 56.3% (95% CI 49-63%), and obstructive sleep apnoea resolution was 51.7% (95% CI 16.2-87.3%) in four studies (n = 480). This pooled analysis demonstrates that ESG can induce durable weight loss and resolution of obesity-associated comorbidities in patients with moderate obesity.

Abstract
We are currently in a worldwide obesity pandemic, which is one of the most significant health problems of the 21st century. As the prevalence of obesity continues to rise, new and innovate treatments are becoming available. Metabolic and bariatric endoscopic procedures are exciting new areas of gastroenterology that have been developed as a direct response to the obesity crisis. These novel interventions offer a potentially reversible, less invasive, safer, and more cost-effective method of tackling obesity compared to traditional bariatric surgery. Minimally invasive endoscopic treatments are not entirely novel, but as technology has rapidly improved, many of the procedures have been proven to be extremely effective for weight loss and metabolic health, based on high-quality clinical trial data. This mini-review examines the existing evidence for the most prominent metabolic and bariatric procedures, followed by a discussion on the future trajectory of this emerging subspecialty.

Abstract
BACKGROUND Endoscopic sleeve gastroplasty is an example of endoscopic sutured plications being used to remodel a gastrointestinal organ. With per-oral plication of the esophagus (POPE), similar plications are used to remodel the dilated and redundant megaesophagus of end-stage achalasia. Redundancies and dilations can also develop in the neoesophagus of a patient with prior esophagectomy. Megaesophagus and a redundant neoesophagus can both lead to debilitating dysphagia, regurgitation, and recurrent aspiration pneumonia. Traditionally, this anatomic problem requires complex revisional or excisional surgery, to which POPE offers an incisionless alternative. METHODS This is a dynamic manuscript with video demonstration of POPE, as well as review of five cases performed in 1 year. Data were collected in a prospectively maintained database, and the institutional review board approved retrospective review for this publication. The procedure is performed using a dual-channel upper endoscope fixed with an endoscopic suturing device, with the patient supine under general anesthesia. RESULTS POPE was technically completed in all cases with no serious complications, and patients either went home the same day or spent one night for observation. Most patients reported immediate and substantial symptomatic improvement. Objective pre- and post-measures include esophagram and nuclear gastric emptying studies. CONCLUSION This article discusses early experience at one institution with POPE, with detailed description of the procedure and technical considerations. An accompanying video reviews two cases, one with megaesophagus and one with a gastric conduit. While this novel procedure has limited and rare indications, it offers a low-morbidity solution to a challenging anatomic problem that traditionally requires invasive surgery.

Abstract
The obesity epidemic in the USA and worldwide is well documented and continues to grow. Endoscopic metabolic and bariatric therapies may offer a less invasive approach than surgical intervention. This article will review advances in endobariatrics over the last several decades, addressing the past and current state of bariatric and metabolic endoscopy. Food and Drug Administration-cleared devices and interventions currently under investigation are described including gastric devices, gastric remodeling procedures, small-bowel devices, duodenal ablation, as well as procedures to address weight regain after bariatric surgery. Future studies evaluating gastric and duodenal combination therapy, adjunctive pharmacotherapy, as well as individualized precision-health algorithms are underway.

Abstract
Background Endoscopic sleeve gastroplasty (ESG) has emerged as an effective endoscopic bariatric procedure over the past decade. Data comparing short-term outcomes of ESG based on operator specialty is scarce. We aimed to assess the impact of operator specialization on patient outcomes using a large bariatric-specific database. Methods We identified a retrospective cohort of patients who underwent ESG by gastroenterologists using the Metabolic and Bariatric Surgery Accreditation Quality Improvement Program database (2020-2021). A matched comparison cohort of patients who underwent ESG by surgeons was identified and underwent 1:1 propensity score matching based on age, race, gender, American Society of Anesthesiologists physical status classification, and preoperative body mass index. Results After matching, 154 patients were included in the final analysis. Of these, 77 patients underwent ESG by surgeons and 77 by gastroenterologists. In the matched cohort, the median operation time was lower in ESG by surgeons compared to gastroenterologists (P < 0.001). The median percent body mass index decrease was higher in the gastroenterologist cohort compared to the surgeon cohort (4.9% vs 3.8%, P = 0.04). The median percent weight loss after ESG was 4.8% in the surgeon cohort and 5.9% in the gastroenterologist cohort (P = 0.09). There was no statistically significant difference in postoperative emergency department visits (P = 0.65), reoperations (P = 0.15), or reinterventions within 30 days (P = 0.87) between the cohorts. There was no difference in major adverse effects between the groups (0% each). Conclusions Operator choice does not affect ESG-related adverse events or 30-day outcomes in patients undergoing ESG.

Abstract
The aim of this study was to evaluate the safety and efficacy of the endoscopic sleeve gastroplasty (ESG) procedure. Patients ineligible for bariatric surgery due to comorbidities or low Body Mass Index (BMI) were offered ESG. Gastric tubularization was carried out via multiple multi-bite sutures across the greater curvature of the stomach. The patients underwent a water-soluble swallow test on post-operative day 1 (POD-1) to assess gastric emptying and were placed on a soft diet if upper GI tract function was confirmed. From January 2019 to March 2022, 27 patients underwent ESG: 14 for severe obesity with comorbidities, including liver transplant, end-stage kidney disease, severe cardiovascular and respiratory diseases. The mean BMI before treatment was 36 ± 9 kg/m2. Two patients (7%) who developed gastric bleeding were successfully treated with packed red blood cells (PRBC) transfusions. After a mean follow-up of 18 months, the percentage of total body weight loss (%TBWL) and the percentage of excess weight (%EWL) were 11 ± 7 and 39 ± 27, respectively. The latter was significantly higher in the patients with an initial BMI < 40 kg/m2 (50 vs 22, p < 0.05). The patients whose gastric sleeve extended for more than a third of the length of the stomach (p < 0.05) had better results. ESG was found to be effective and safe in high-risk surgical patients whose initial BMI was (< 40). Studies characterized by larger number of patients and longer follow-up periods will be able to confirm these results.

Abstract
Background and study aims This was a single-blind, single-center, prospective randomized controlled trial aimed at comparing the efficacy of three different suture patterns for endoscopic sleeve gastroplasty using Endomina (E-ESG). Patients and methods The suture patterns aimed to modify gastric accommodation by increasing the fundus distention ability (Group A), to reduce gastric volume (Group B) or to interrupt gastric emptying (Group C). Patients were randomized 1:1:1 and underwent clinical follow-up, gastric emptying scintigraphy, and satiety tests at baseline and 6 and 12 months post-procedure. The primary outcome was total body weight loss (TBWL) and excess weight loss (EWL) at 12 months post-procedure. Secondary outcomes included the impact of the suture patterns on gastric emptying and satiety. Results Overall, 48 patients (40 [83.3 %] female, aged 41.9 ± 9.5 years, body mass indexI 33.8 ± 2.7 kg/m 2 ) were randomized (16 in each group). In the entire cohort, mean (95 % confidence interval [CI]) TBWL and EWL at the end of the follow-up were 10.11 % (7.1-13.12) and 42.56 (28.23-56.9), respectively. There was no difference among the three study groups in terms of TBWL (95 %CI) (9.13 % [2.16-16.11] vs. 11.29 % [5.79-16.80] vs. 9.96 % [4.58-15.35]; P = 0.589) and EWL (95 %CI) (34.54 % [6.09-62.99] vs. 44.75 % [23.63-65.88] vs. 46.94 % [16.72-77.15]; P = 0.888) at 12 months post-procedure. The three groups did not differ in terms of mean gastric emptying time or in terms of satiety tests at the end of the follow-up. No serious adverse events occurred. Conclusions Three different suture patterns during E-ESG demonstrated comparable efficacy in terms of weight loss, with an overall EWL of > 25 % and TBWL of > 10 % at 12 months.

Persistence of Sutures and Gastric Reduction After Endoscopic Sleeve Gastroplasty: Radiological and Endoscopic Assessment. Obes Surg 2022; 32:1969-1979. [PMID: 35353330 DOI: 10.1007/s11695-022-06039-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2021] [Revised: 03/19/2022] [Accepted: 03/22/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND Endoscopic sleeve gastroplasty (ESG) is an effective medium-term procedure for obesity treatment. There are no consistent studies confirming persistence of maintained gastric tubular configuration. We determined sleeve duration, gastric reduction degree, and suture persistence at 12-month follow-up. PATIENTS AND METHODS This is a prospective, single-center study, including patients with obesity undergoing ESG with at least 1-year follow-up, who underwent the following: (1) Barium X-ray study (BS) prior and at 6 months, assessing degree of gastric reduction (severe, moderate, or mild), and (2) gastroscopy at 12 months, accounting the number of persistent sutures (tense, lax, or absent). Secondary outcomes were weight loss data and procedure safety profile. RESULTS Thirty-eight patients (30 women), median age of 47.0 [40.0-51.0] years, and average baseline BMI of 37.6 [35.5-41.5] kg/m2 were included. Median %TWL of 17.1% [16.1-22.3%] with TWL > 10% in 94.7% of patients was obtained at 1 year. No major AEs were observed. Six months BS was performed on 30 patients: 12 (40.0%), 14 (46.7%), and 4 (13.3%) patients showed severe, moderate, and mild gastric reduction, respectively. Twelve months gastroscopy was performed on 22 patients with 83.64% of sutures persisting (92 of 110, mean 4.2 of 5.0 sutures/patient) and 70.9% with adequate tension. We found intact sutures in 12 patients (54.5%), and 10 patients (45.5%) had some suture detached (average 1.8, r = 1-3). There were no differences in %TWL according to BS reduction (p = 0.662) or number of persistent sutures (p = 0.678). CONCLUSIONS ESG is an effective and safe weight loss strategy at 12-month follow-up with persistence of most sutures and maintenance of notable gastric reduction and remodeling.

Abstract
Since its first description in 2013, robust evidence supporting the efficacy and safety of the endoscopic sleeve gastroplasty (ESG) has been on the rise. A large case series and meta-analysis report supported results up to 24 months, while some other studies already described 5-year data. If associated with pharmacotherapy, the ESG may help one to achieve weight loss similar to that of surgical sleeve gastrectomy. Though the results of the ongoing randomized trials on ESG are awaited, currently available data support the clinical use of the ESG, especially for patients who are refusing or unfit for bariatric surgery.

Abstract
The field of endoscopic bariatric and metabolic therapy has rapidly evolved from offering endoscopic treatment of weight regain following bariatric surgery to providing primary weight loss options as alternatives to pharmacologic and surgical interventions. Gastric devices and remodeling procedures were initially designed to work through a mechanism of volume restriction, leading to earlier satiety and reduced caloric intake. As the field continues to grow, small bowel interventions are evolving that may have some effect on weight loss but focus on the treatment of obesity-related comorbidities. Future implementation of combination therapy that utilizes both gastric and small bowel interventions offers an exciting option to further augment weight loss and alleviate metabolic disease. This review considers gastric devices and techniques including space-occupying intragastric balloons, aspiration therapy, endoscopic tissue suturing, and plication interventions, followed by a review of small bowel interventions including endoluminal bypass liners, duodenal mucosal resurfacing, and endoscopically delivered devices to create incisionless anastomoses. Expected final online publication date for the Annual Review of Medicine, Volume 73 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Abstract
PURPOSE OF REVIEW To provide updated evidence on the endoscopic procedures for weight loss and to bring personal insights on the future of endobariatrics. RECENT FINDINGS Intragastric balloons promote significant improvement in histologic and radiologic aspects of non-alcoholic steatohepatitis; the endoscopic sleeve gastroplasty is effective up to 5 years and seems particularly beneficial to patients with BMI≤40kg/m2; distal POSE is a promising technique but still lacks adequate clinical data; aspiration therapy triggers remarkable weight loss, but data on weight trends after removal of the device are still lacking; the satiety-inducing device, the sleeveballoon, the gastric mucosal devitalization, and the endoscopic magnetic partial jejunal diversion are promising procedures still under study and refinements. Several therapeutic options are necessary during obesity's natural history. Therefore, endobariatrics should act in harmony with lifestyle interventions, diet modification, psychological treatment, pharmacotherapy, and bariatric surgery seeking the best outcome in the long term.

Abstract
Endoscopic sleeve gastroplasty (ESG) is a therapeutic endoscopic technique for reducing the size of the gastric reservoir in obese patients, using a full-thickness endoscopic suturing device. The effectiveness of ESG in weight loss is significantly greater than that of high-intensity diet and lifestyle therapy and lower than that of laparoscopic sleeve gastrectomy (LSG). The efficacy at 12 months after ESG in terms of percentage of total body weight loss and excess body weight loss was approximately 16% and 60%, respectively. The well-known predictive factors for increased weight loss by ESG are good compliance with regular monitoring and post-procedure care involving a multidisciplinary team approach. Although the underlying mechanism of weight loss induced by ESG is debatable, delayed gastric emptying and early satiation are some of the proposed mechanisms. The pooled rate of adverse events after ESG reported in several meta-analysis studies ranged from 1.5% to 2.3% and the incidence of new-onset gastroesophageal reflux disease after ESG was negligible, indicating that ESG has a superior safety profile to LSG. Moreover, ESG reduced the risk of obesity-related metabolic comorbidities, evidenced by the reduction in HbA1c level, systolic blood pressure, triglyceride level, and risk of hepatic steatosis and fibrosis; it even improved the quality of life. ESG could be considered safe and qualify as an alternative treatment to LSG.
