Learning curve analysis of endoscopic sleeve gastroplasty in standardized Bama miniature pigs:an animal experiment

To the Editor:Endoscopic sleeve gastroplasty(ESG)is a recently developed incisionless transoral gastroscopic bariatric procedure that can shrink the gastric cavity into a tubular structure similar to the capacity of surgical sleeve gastrectomy by means of endoscopic full-thickness sutures.Clinical practice has proven its safety,durability,minimal invasiveness,and long-term weight loss effects,which are close to those of bariatric surgery.
