Abstract: Bariatric and metabolic surgery originated in the 1950s. After continuous verifications and improvements by bariatric and metabolic surgeons all over the world, bariatric surgery has been recognized as the ‘gold standard’ for the treatment of metabolic diseases such as obesity. In the development of more than half a century, bariatric and metabolic surgery have formed a variety of classic surgical methods. At the same time, the new methods of bariatric surgery are emerging. Among them, the additional surgery based on sleeve gastrectomy has become a research hotspot. In the process of clinical applications of various new bariatric surgery methods, bariatric and metabolic surgeons should be objective, accurate, realistic, and move forward on the basis of criticizing and absorbing. The authors investigate the influence of new surgical methods on the development of bariatric and metabolic surgery.
