Bariatric surgery is the most efficacious treatment of obesity and type 2 diabetes mellitus. Novel endoscopic methods based on the principles of bariatric surgery are also highly effective. No direct randomized comparison of both types of treatment has been performed to date and the mechanisms of action of both procedures are still only partially clarified. The aim of the project is to perform a randomized trial comparing efficacy and safety of three treatment options in patients with obesity: laparoscopic sleeve gastrectomy, endoscopic gastric plication and conservative treatment. A further aim is to characterize the influence of the three treatments on subclinical inflammation, gut microbiota composition and changes of gastrointestinal hormones. The results of the project will describe the efficacy and safety of these procedures as compared to conservative therapy and clarify the mechanisms of action of these treatments. The project will also contribute to more precise indications of bariatric or endoscopic methods in clinical practice and enable personalized choice of therapy for particular patient.
