Embolization of Arterial Gastric Supply in Obesity (EMBARGO): an Endovascular Approach in the Management of Morbid Obesity. Proof of the Concept in the Porcine Model

摘要

Background Embolization of the left gastric artery (LGA) reduces circulating levels of ghrelin, but might prevent from further obesity surgery, particularly sleeve gastrectomy (SG), since the gastroesophageal junction (GEJ), depending on LGA, would be devascularized. Our aim was to evaluate, in an experimental animal study, an endovascular approach targeting arteries of the gastroepiploic arcade aiming to modulate ghrelin levels and to generate an increased vascular supply of the GEJ to reduce the risks of staple-line leaks after SG.
