The field of obesity or localized obesity surgeries is characterized by continuous development and the emergence of new operations and their replacement by old ones when their ineffectiveness was proven by medical studies. In the eighties, the process of stapling the stomach appeared, then it was replaced by the process of the stomach belt or ring, then the process of folding and ruffles the stomach appeared, and lately the process of sleeve gastrectomy .
