BMC Gastroenterol 2023; 23:375. [PMID: 37915010 PMCID: PMC10621135 DOI: 10.1186/s12876-023-03000-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/15/2022] [Accepted: 10/15/2023] [Indexed: 11/03/2023] Open
Abstract
BACKGROUND Natural orifice transluminal endoscopy surgery (NOTES) gastrojejunal anastomosis (GJA) with duodenal exclusion (DE) could be used as a less invasive alternative to surgical gastric bypass. The aim of this study was to compare the efficacy and safety of both methods for bariatric purpose. METHODS This was a prospective, experimental and comparative study on 27 obese living pigs, comparing 4 groups: GJA alone (group 1, G1), GJA + DE (group 2, G2), surgical gastric bypass (group 3, G3), control group (group 4, G4). GJA was endoscopically performed, using NOTES technic and LAMS, while DE was performed surgically for limb length selection. Animals were followed for 3 months. Primary outcome included technical success and weight change, while secondary endpoints included the rate of perioperative mortality and morbidity, histological anastomosis analysis and biological analysis. RESULTS Technical success was 100% in each intervention group. No death related to endoscopic procedures occurred in the endoscopic groups, while early mortality (< 1 month) was 57,1% in the surgical group, all due to anastomotic dehiscence. At 3 months, compared to baseline, mean weight change was + 3,1% in G1 (p = 0,46); -14,9% in G2 (p = 0,17); +5,6% in G3 (p = 0,38) and + 25% in G4 (p = 0,029). Histopathological analysis of endoscopic GJA showed complete fusion of different layers without leak or abscess. CONCLUSIONS Endoscopic GJA with DE provides the efficacy of bypass on weight control in an animal model. Next steps consist of the development of devices to perform exclusively endoscopically limb length selection and DE.

Abstract
Obesity poses a significant health care concern in the United States, with 39.8% of adults being classified as obese. Several different methods have been introduced to combat obesity, from medical therapy to surgical options. Bariatric surgery has been demonstrated to be superior to medical therapy alone for weight loss in obese patients. Despite this information, only about 1% of eligible patients undergo bariatric surgery per year. The reason for this treatment gap is multifactorial, but patient apprehension to undergo surgery is a major driving force. Many patients perceive bariatric surgery as dangerous, and believe that living with their current weight is safer than undergoing surgery. To combat this treatment gap, endoscopic therapies have been developed to reach more patients in a less invasive way. This article will review endoscopic treatment options currently available and approved by the Food and Drug Administration, as well as other treatment modalities that are currently in development.

Abstract
BACKGROUND The healthcare impact of obesity is enormous, and there have been calls for new approaches to containing the epidemic worldwide. Minimally invasive procedures have become more popular, with one of the most widely used being endoscopic sleeve gastroplasty (ESG). Although major adverse events after ESG are rare, some can cause considerable mortality. To our knowledge, there has been no previous report of biliary ascites after ESG. CASE SUMMARY A 48-year-old female with obesity refractory to lifestyle changes and prior gastric balloon placement underwent uncomplicated ESG and was discharged on the following day. On postoperative day 3, she developed abdominal pain, which led to an emergency department visit the following day. She was readmitted to the hospital, with poor general health status and signs of peritoneal irritation. Computed tomography imaging showed fluid in the abdominal cavity. Laparoscopy revealed biliary ascites and showed that the gallbladder was sutured to the gastric wall. The patient underwent cholecystectomy and lavage of the abdominal cavity and was admitted to the intensive care unit post-operatively. After 7 d of antibiotic therapy and 20 d of hospitalization, she was discharged. Fortunately, 6 mo later, she presented in excellent general condition and with a 20.2% weight loss. CONCLUSION ESG is a safe procedure. However, adverse events can still occur, and precautions should be taken by the endoscopist. In general, patient position, depth of tissue acquisition, location of stitch placement, and endoscopist experience are all important factors to consider to mitigate procedural risk.

Abstract
BACKGROUND Obesity is a disease that is highly prevalent in Brazil, and the associated comorbidities represent a major global public health challenge. Botulinum toxin type A (BTX-A) is a potent neurotoxin and inhibitor of gastric smooth muscle activity. In theory, BTX-A administration should promote early satiety and weight loss because it delays gastric emptying by inhibiting acetylcholine-mediated peristalsis, which is primarily responsible for gastric motility. Because results in the literature are discrepant, the efficacy of intragastric injections of BTX-A as a primary treatment for obesity remains unknown. The objective of this prospective, double-blind, single-center randomized study was to evaluate the effects of endoscopic ultrasound-guided intragastric BTX-A injections, as a bridge to bariatric surgery, in super-obese patients. METHODS Thirty-two super-obese patients were randomized to one of two groups: BTX-A, in which 200 units of BTX-A were injected into the gastric antrum and body; and control, in which the same injections were performed with 0.9% saline. Weight, body mass index (BMI), and loss of excess weight were measured monthly over a 6-month period. Gastric emptying scintigraphy was performed before and after the procedure. RESULTS The patients in both groups showed significant weight loss over the course of the study (p < 0.001). There were no statistically significant differences between the groups regarding weight loss, excess weight, total loss of excess weight, total weight loss, or change in BMI. CONCLUSIONS Intragastric injection of BTX-A does not appear to be an effective method of achieving preoperative weight loss in super-obese patients.

Abstract
BACKGROUND AND AIMS Obesity is a pandemic affecting approximately 700 million adults worldwide, with an additional 2 billion overweight. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive endoscopic bariatric therapy that involves remodeling of the greater curvature in an effort to reduce gastric capacity and delay gastric emptying. A variety of ESG suture patterns has been reported. This study is the first to use a uniform "U" stitch pattern across all centers to simplify technical aspects of the procedure and limit cost. This also uniquely assessed outcomes in all body mass index (BMI) categories and changes in metabolic rate, lean body mass, and adipose tissue composition. METHODS This is a multicenter analysis of prospectively collected data from 7 centers including patients with overweight and obesity who underwent ESG. Primary outcomes included absolute weight loss, percent total body weight loss (%TWL), change in BMI, and percent excess weight loss (%EWL) at 6 and 12 months in overweight and obese classes I, II, and III. Secondary outcomes included adipose tissue, lean body mass reduction, and metabolic rate analyzed by bioimpedance. Additionally, immediate or delayed adverse events (AEs) were analyzed. Clinical success was defined as achieving ≥25% EWL at 1 year with ≤5% serious AE (SAE) rate following the American Society for Gastrointestinal Endoscopy (ASGE)/American Society for Metabolic and Bariatric Surgery (ASMBS) threshold. RESULTS A total of 193 patients underwent ESG during the study period. All groups had >10% TWL and >25% EWL at 6 months of follow-up. On average, %TWL was 14.25% ± 5.26% and 15.06% ± 5.22% and the %EWL 56.15% ± 22.93% and 59.41% ± 25.69% at 6 months and 1 year of follow-up, respectively. %TWL was 8.91% ± .3%, 13.92% ± 5.76%, 16.22% ± 7.69%, and 19.01% ± .95% and %EWL 56.21% ± 2.0%, 62.03% ± 27.63%, 54.13% ± 23.46%, and 46.78% ± 2.43% for overweight and obesity classes I, II, and III, respectively, at 1 year. Male sex, age <41 years, and higher BMI were predictors of achieving a TWL ≥10% at 1-year follow-up. There was a significant reduction in adipose tissue from baseline. SAEs occurred in 1.03%, including 2 perigastric collections needing surgery. CONCLUSIONS ESG appears to be feasible, safe, and effective in the treatment of patients with overweight and obesity according to ASGE/ASMBS thresholds.

Abstract
A gastrointestinal (GI) transmural defect is defined as total rupture of the GI wall, and these defects can be divided into three categories: perforations, leaks, and fistulas. Surgical management of these defects is usually challenging and may be associated with high morbidity and mortality rates. Recently, several novel endoscopic techniques have been developed, and endoscopy has become a first-line approach for therapy of these conditions. The use of endoscopic vacuum therapy (EVT) is increasing with favorable results. This technique involves endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. This promotes healing via five mechanisms, including macrodeformation, microdeformation, changes in perfusion, exudate control, and bacterial clearance, which is similar to the mechanisms in which skin wounds are treated with commonly employed wound vacuums. EVT can be used in the upper GI tract, small bowel, biliopancreatic regions, and lower GI tract, with variable success rates and a satisfactory safety profile. In this article, we review and discuss the mechanism of action, materials, techniques, efficacy, and safety of EVT in the management of patients with GI transmural defects.

Abstract
The most effective and durable treatment for obesity is bariatric surgery. However, less than 2% of eligible patients who fulfill the criteria for bariatric surgery undergo the procedure. As a result, there is a drive to develop less invasive therapies to combat obesity. Endoscopic bariatric therapies (EBT) for weight loss are important since they are more effective than pharmacological treatments and lifestyle changes and present lower adverse event rates compared to bariatric surgery. Endoscopic sleeve gastroplasty (ESG) is a minimally invasive EBT that involves remodeling of the greater curvature. ESG demonstrated favorable outcomes in several centers, with up to 20.9% total body weight loss and 60.4% excess weight loss (EWL) on 2-year follow-up, with a low rate of severe adverse events (SAE). As such, it could be considered safe and effective in light of ASGE/ASMBS thresholds of > 25% EWL and ≤ 5% SAE, although there are no comparative trials to support this. Additionally, ESG showed improvement in diabetes mellitus type 2, hypertension, and other obesity-related comorbidities. As this procedure continues to develop there are several areas that can be addressed to improve outcomes, including device improvements, technique standardization, patient selection, personalized medicine, combination therapies, and training standardization. In this editorial we discuss the origins of the ESG, current data, and future developments.

Abstract
INTRODUCTION With the cumulative increase in the number of patients undergoing bariatric surgery, postoperative weight regain has become a considerable challenge. Mechanisms for weight regain are not fully understood and the process is likely multifactorial in many cases. Endoluminal revisions that reduce gastric pouch size and diameter of the gastrojejunal anastomosis may offer an effective and less invasive management strategy for this population. AREAS COVERED We critically review data from case series, retrospective and prospective studies, and meta-analyses pertaining to weight regain after gastric bypass. A variety of endoscopic revision approaches are reviewed, including technique details, procedural safety and efficacy, and post-procedure care. EXPERT COMMENTARY Given the proliferation of endoluminal therapies with evidence showing safety and efficacy in the treatment of weight regain, it is likely that endoscopic revision will be the gold standard to treat weight regain in patients with gastric bypass.

Abstract
Background and study aims Obesity is a serious disease, resulting in significant morbidity and mortality. Intragastric balloons (IGBs) have been in use since the 1980s. After the insertion of an IGB, complications such as migration of the device and even severe gastric perforation can occur, requiring laparoscopic surgery. Here, we report three cases of gastric perforation after IGB insertion. In all three cases, the perforation was successfully repaired through an exclusively endoscopic approach.
