Endoscopic Gastric Mucosal Devitalization (GMD) as a Primary Obesity Therapy

During routine laparoscopic sleeve gastrectomy surgery, once the greater curvature of the stomach is excised as per normal surgical technique, the investigators will take the specimen out and perform an ablation ex-vivo, with the intention of performing selective mucosal devitalization. This specimen will then be transported to pathology lab for analysis.
