简要总结
The purpose of this research is to investigate the combined effects of fundic ablation (FA) and endoscopic sleeve gastroplasty on circulating plasma ghrelin, satiation, and total body weight loss, as well as the incidence of adverse events. This procedure will be carried out with the HybridAPC (ERBE Elektromedizin GmbH, Tübingen, Germany). The HybridAPC instrument creates an electric current to deliver a safe amount of thermal injury to a portion of the stomach known as the gastric fundus. This thermal injury will target a hormone called ghrelin which is the only known hormone linked to increasing appetite, calorie intake, and weight gain. This procedure is designed to target the bodily effects of appetite control and gastric sensory and motor functions which cause the feeling of fullness and satiation. When fundic mucosal ablation is paired with endoscopic sleeve gastroplasty (ESG), this combined investigational approach may lead to decreased fasting ghrelin levels, improved satiation, and greater total body weight loss than traditional ESG. This study will help determine if the combined impact of FA with ESG within the same endoscopic session should be made available to patients as part of a comprehensive weight loss strategy.
详细描述
Obesity is a chronic disease state driven by the imbalance of caloric intake and expenditure and mediated by multiple central and peripheral pathways that may serve as targets for therapeutic interventions. The endoscopic sleeve gastroplasty (ESG) is a per oral gastric remodeling technique that employs full-thickness suturing to imbricate the stomach along the greater curvature to achieve a restricted, sleeve-like configuration. While the ESG recapitulates the configuration of a gastric sleeve, it has not yet been shown to achieve as robust weight loss outcomes compared to the laparoscopic sleeve gastrectomy (LSG). A major difference between ESG and LSG is that the former does not involve the gastric fundus. The proximal stomach, and the fundus in particular, produces ghrelin, the only known orexigenic hormone, which has been linked to increased calorie intake and weight gain. Studies have observed reduced levels of ghrelin along multiple timepoints following LSG, and this has been attributed to targeting of the fundus, as bariatric surgeries that did not involve the fundus did not see a decrease in circulating plasma ghrelin. In contrast, in a small comparative study of ESG and LSG, patients who had undergone ESG did not show any decrease in fasting ghrelin levels, 8 ostensibly due to fundic-sparing. In this study, the investigators propose to investigate the effects of fundic ablation (FA-ESG) on total body weight loss (TBWL) as well as the incidence of adverse events. Fundic ablation will be followed with ESG, to evaluate the combined impact of FA and ESG (FA-ESG). This study hypothesizes that the combined endoscopic intervention (FA-ESG) will result in significant weight loss while maintaining an acceptable safety profile
