In fact, over the 60 years of development of bariatric surgery, dozens of procedures have been tried clinically, and only a few procedures with excellent results and safety have been summarized with the accumulated experience. Even though several common procedures have become increasingly popular worldwide, the field of bariatric and diabetic surgery has never ceased to explore new procedures. Some of these procedures have already received industry recognition and have begun intensive clinical research. Perhaps, this will be a major change in bariatric surgery. Mini-gastric bypass, which was first proposed in 2001, is a simplified version of gastric bypass surgery. However, it has not been widely used because of the high incidence of postoperative complications such as diarrhea and malnutrition. Some time ago, a French scientist conducted a study showing that mini-gastric bypass was as effective as conventional gastric bypass in weight loss and glucose reduction, and felt that the procedure had great promise for development. This news has attracted attention in the field of bariatric surgery and is now a hot topic of research at home and abroad, and it is believed that it will be gradually carried out in the near future. The intragastric balloon was developed in the United States in 1984, but the quality of the balloon was not guaranteed due to the material problem, which could easily lead to postoperative complications such as ulceration, perforation and obstruction, so it was not promoted. After improvement, the gastric hydrosphere appeared in 1990, and there was a new breakthrough in the sphere content as well as the material, but it could only stay in the stomach for 6 months, but the innovation of the gastric hydrosphere procedure made many scientists see that this direction is feasible. Currently, the American Society for Diabetes and Obesity Surgery has included this procedure as one of the recommended procedures for weight loss, and although it is not yet approved for clinical use in China, related clinical studies have already begun. The future of bariatric surgery will be easier, more effective and safer.
