Many people may be hearing about it for the first time. For a long time, when it comes to the treatment of diabetes, the concept of “five horses” going hand in hand has been deeply rooted in people’s minds, and the concept that diabetes requires lifelong medication and insulin is also deeply rooted in the minds of many “sugar lovers”. However, with the advancement of medicine, the effectiveness of surgery in treating diabetes has been proven. Currently, international literature reports that bariatric surgery has a complete remission rate of about 80% for type 2 diabetes, with an effective rate of over 95% and a follow-up period of 10-15 years. Tracing back the history, metabolic surgery can actually treat type 2 diabetes for a hundred years. As early as 1925, The Lancet published an article describing a case of gastrointestinal surgery on a patient with peptic ulcer, in which doctors found that gastrointestinal surgery had a therapeutic effect on diabetes. Similar reports followed. In 1982, Pories, a surgeon at the University of North Carolina, discovered by chance that bariatric surgery was effective in treating type 2 diabetes while reducing weight, and in 1995, after 14 years of clinical follow-up, Pories published his findings that bariatric surgery had a “cure rate” of 83% for obese type 2 diabetes. In 1995, after 14 years of clinical follow-up, Pories published his findings that bariatric surgery had an 83% “cure rate” for obesity and type 2 diabetes, thus creating a new way to treat type 2 diabetes with surgery. In 2016, the world’s first joint guideline on metabolic surgery for type 2 diabetes, developed with the participation of several international diabetes organizations, was released, and Nature published a simultaneous review of this landmark guideline, which will The landmark guideline will have a significant impact on the global treatment of diabetes. The Joint Guideline on Metabolic Surgery for Type 2 Diabetes states that diabetes is a disease of the gastrointestinal tract, the largest endocrine organ in the body, rather than a disease caused by islet cell dysfunction in the traditional sense. Then, diabetes can be treated through gastric bypass surgery, the most common of metabolic surgeries, which is another example of treating a functional disease through surgery. In summary, surgery has become a new option in the treatment of diabetes. With the widespread implementation of minimally invasive techniques nationwide, we believe that surgery will benefit more and more diabetic patients.
