Surgical procedures have become the only long-term effective treatment for obesity. Laparoscopic gastric diversion can effectively treat type II diabetes, and patients no longer need insulin after surgery. Reducing “sugar” After surgery, no longer take hypoglycemic drugs In China, there are about 90 million diabetic patients, of which more than 90% are type II diabetes. “These patients rely on medication or insulin injections to maintain their blood sugar for a long time, which greatly reduces their quality of life, and it is difficult to avoid possible complications caused by diabetes even if they maintain normal blood sugar, so there is an urgent need for new and effective ways to treat diabetes.” In the 1950s, foreign doctors found after performing bariatric surgery that some obese patients with diabetes had significantly reduced insulin dosage after bariatric surgery, and that the glucose-lowering effect appeared before weight loss. In addition, it was also found clinically that some diabetic patients who underwent major distal gastric resection also experienced a decrease in blood glucose after surgery, which led to a boom in research on surgical treatment of type II diabetes. One reason why gastric diversion surgery can treat type II diabetes is that, on the one hand, in the upper digestive tract, there are a large number of K cells distributed on the mucosa, which secrete a large amount of insulin resistance factor once stimulated by food, causing the body to develop insulin resistance, which is the initial cause of diabetes formation. After the digestive tract is surgically modified, the upper digestive tract no longer receives food stimulation and K cells no longer secrete insulin resistance factor. On the other hand, after the surgery, the incompletely digested food can enter the middle and lower digestive tract earlier and stimulate a large number of L cells in the mucosa of the middle and lower digestive tract, which then secrete certain cytokines that directly lower blood sugar and stimulate the proliferation of pancreatic islet cells, thus helping patients to improve their islet function. Weight loss can effectively control obesity complications “In addition to diabetes, obesity can lead to a variety of complications such as hypertension, hyperlipidemia, fatty liver, obstructive sleep apnea, gastroesophageal reflux disease, depression, menstrual disorders, asthma and osteoarthritis or degenerative lesions.” The number and severity of concomitant diseases increases significantly with the course and age of obese patients. Obesity in adults can cause diseases directly related to life expectancy, shortening life expectancy by an average of about seven years. ”Laparoscopic adjustable gastric banding”, “laparoscopic gastric diversion” and “laparoscopic sleeve gastrectomy”, three of the most advanced and popular international surgical techniques for weight loss On the premise of minimally invasive surgery, they limit the excessive intake of obese patients on the one hand and the excessive absorption of obese patients on the other. Years of clinical practice shows that laparoscopic minimally invasive surgical gastric reduction surgery for obesity and type II diabetes has an effective satisfaction rate of 85% to 97% in the medium and long term, and reduces overweight weight by 70-80% after surgery, which has now become the only long-term effective method for treating obesity. Laparoscopic surgery has the advantages of small incision, less bleeding, less pain, faster recovery and fewer complications, and can be completed within 2 hours. Patients are usually able to eat 3 days after surgery and can be discharged in 1 week.
