*3.1.2 Endoscopic sleeve gastroplasty (ESG)*

Another system to create a restrictive sleeve is the Overstitch system (Apollo Endosurgery, Austin, Texas, USA). Contrary to the TOGA system, it applies fullthickness running sutures alongside the greater curvature of the stomach. This results in a reduction of the functional capacity of the stomach by up to 70%, a size comparable to the reduction of the gastric lumen in laparoscopic sleeve gastrectomy (LSG) [19]. This device is currently commercially available in the United States.
