Automatic Endoscopic Gastroplasty For The Treatment of Obesity: Results from A Prospective Multicenter Study.

BACKGROUND AND AIMS: EndoZipTM is a fully automated operator independent robotic endoscopic suturing device developed for gastric volume reduction and treatment of obesity. We aim to assess the efficacy and safety of EndoZipTM to treat patients with obesity. METHODS: We conducted a prospective multicenter study and recruited 45 patients with a BMI of 30-40 kg/m2. Our primary outcome was to assess the percentage total body weight loss (%TBWL) at 12 months. The secondary outcome was to determine the safety and change in quality of life using the IWQOL questionnaire at 1 year. RESULTS: The mean ±SD age was 44.2 ± 8.8 years, and the mean ±SD BMI was 34.5 ± 2.9 Kg/m2. A majority (90.7%) were female. The procedure was technically successful in all patients (100%). A median of 4 (range, 3-5) full-thickness sutures were placed, and the mean procedure time was 30.8 ± 15.8 minutes. At 12-months, the mean %TBWL was 13.21 (95% CI: 10.11- 16.31%) and 76.6% of patients achieved >5% TBWL. We observed significant reduction in waist circumference, HbA1C, and ALT levels at 12 months (p<0.001). We found a significant improvement in quality of life at 12 months (51.28 ±16.22 vs. 35.8±11.9, p<0.001). Serious adverse events occurred in 2 patients (4.4%). The average length of stay was 1 day. CONCLUSION: Our first-in-human study showed that the EndozipTM device is safe and effective in treating obesity. The weight loss led to comorbid changes and improvement in quality of life (Clinicaltrials.gov, NCT04773795).

Endoscopic sleeve gastroplasty for metabolic dysfunction-associated steatotic liver disease.

INTRODUCTION: Metabolic dysfunction-associated steatotic liver disease (MASLD, formerly nonalcoholic fatty liver disease - NAFLD) is a chronic liver condition linked to obesity and metabolic syndrome. It affects one-third of people globally and, in some cases, can lead to metabolic dysfunction-associated steatohepatitis (MASH, formerly nonalcoholic steatohepatitis, NASH) and fibrosis. Weight loss is crucial for the treatment of MASLD, but diet and lifestyle modifications often fail. AREAS COVERED: In recent years, endoscopic sleeve gastroplasty (ESG) has gained popularity as an effective and minimally invasive option for obesity treatment, with widespread use worldwide. We present a current overview of the most significant studies conducted on ESG for the management of obesity and MASLD. Our report includes data from published studies that have evaluated the impact of ESG on noninvasive hepatic parameters used to estimate steatosis and fibrosis. However, at present, there are no data available on liver histology. EXPERT OPINION: ESG has shown promising results in treating MASLD evaluated by noninvasive tests, but current data is limited to small, nonrandomized studies. More research is needed, particularly on the effects of ESG on histologically proven MASH. If future research confirms its efficacy, ESG may be incorporated into treatment guidelines in the future.

Management of fistulas in the upper gastrointestinal tract.

Fistulas in the upper gastrointestinal (GI) tract are complex conditions associated with elevated morbidity and mortality. They may arise as a result of inflammatory or malignant processes or following medical procedures, including endoscopic and surgical interventions. The management of upper GI is often challenging and requires a multidisciplinary approach. Accurate diagnosis, including endoscopic and radiological evaluations, is crucial to build a proper and personalized therapeutic plan, that should take into account patient's clinical conditions, time of onset, size, and anatomical characteristics of the defect. In recent years, several endoscopic techniques have been introduced for the minimally invasive management of upper GI fistulas, including through-the-scope and over-the-scope clips, stents, endoscopic suturing, endoluminal vacuum therapy (EVT), tissue adhesives, endoscopic internal drainage. This review aims to discuss and detail the current available endoscopic techniques for the treatment of upper GI fistulas.

The evolution and current state of bariatric endoscopy in Western countries.

With the alarmingly increasing prevalence of obesity in the Western world, it has become necessary to provide more acceptable treatment options for patients with obesity. Minimally invasive endoscopic techniques are continuously evolving. Currently, metabolic and bariatric endoscopies encompass several different techniques that can offer significant weight loss and improvement in comorbidities with a favorable safety profile. Restrictive bariatric procedures include the use of intragastric balloons and gastric remodeling techniques with different suturing devices. Several studies have demonstrated the efficacy and safety of these techniques that are widely used in clinical practice. Small intestine-targeted metabolic endoscopy is an intriguing and rapidly evolving field of research, although it is not widespread in routine practice. These techniques include duodenal-jejunal bypass liners, duodenal mucosal resurfacing, and incisionless anastomoses. The aim of this review article is to provide a detailed update on the currently available bariatric endoscopy techniques in Western countries.

Success Predictors of Endoscopic Sleeve Gastroplasty.

OBJECTIVE: Endoscopic sleeve gastroplasty (ESG) is a minimally invasive procedure that proved to be safe and effective in obesity treatment. However, not all subjects respond to treatment in the same way, and, with a view to personalized care, it is essential to identify predictors of success or failure. METHODS: A retrospective 2-year followed-up cohort of ESG subjects was analyzed to investigate the presence of any baseline or early indicators of long-term optimal or suboptimal ESG outcomes. RESULTS: A total of 315 subjects (73% women) were included, with 73% of patients exhibiting an Excess weight loss percentage (%EWL) >25% at the 24 months. Neither demographic parameters (age and sex), smoking habits, and menopause in women nor the presence of comorbidities proved potential predictive value. Interestingly, the %EWL at 1 month after ESG was the strongest predictor of 24-month therapeutic success. Subsequently, we estimated an "early threshold for success" for 1 month-%EWL by employing Youden's index method. CONCLUSIONS: ESG is a safe and effective bariatric treatment that can be offered to a wide range of subjects. Early weight loss seems to impact long-term ESG results significantly and may allow proper early post-operative care optimization.
