Laparoscopic gastric sleeve resection, known as laparoscopic gastric reduction surgery, is a procedure that uses a laparoscope to cut out the large curvature of the stomach vertically, mainly for weight loss and treatment of type 2 diabetes. So what are the advantages? The full name is laparoscopic gastric reduction surgery, also known as sleeve gastrectomy. The principle of gastric reduction surgery is to use the laparoscope to cut out the greater curvature of the stomach vertically, so that a small gastric sac of about 150cc is formed in the stomach, which can hold about 4-5 ounces of food. It has the advantage of not requiring the placement of foreign objects in the body and the procedure is remarkably effective for weight loss. Method: 2-6 cm of the sinus above the pylorus is preserved in the direction of the greater curvature of the stomach, and the larger part of the stomach is removed along the long axis of the stomach, and the entire fundus is removed, leaving a “banana-shaped” stomach with a volume of about 60-80 ml. Principle: To reduce the volume of the stomach and decrease the secretion of hormones that stimulate the production of hunger. Advantages: It does not change the physiological state of the gastrointestinal tract and does not interfere with the normal process of digestion and absorption of food. Evaluation: Sleeve gastrectomy has a good therapeutic effect on type 2 diabetes and is a widely used surgery for weight reduction and diabetes in Europe at present. This surgery can reduce more than 70% of overweight weight in the first year after surgery, (about 60 pounds or more for 200 pounds, for example), and the remission rate of diabetes is more than 75%. Of the three, adjustable gastric banding for weight loss (LAGB) and diversion (By-pass), the treatment effect and postoperative complications are in the middle, so it is the most popular. Advantages of sleeve gastric surgery: 1. Bariatric results are similar to gastric bypass surgery and higher than gastric banding. 2. There is no foreign body implanted and no risk of rupture or abrasion. 3. No adjustment is required. 4. The quality of eating is higher than that of the gastric band. 5. Higher safety than gastric bypass surgery. 6. Does not affect the absorption of vitamins and minerals. 7. Fewer long-term side effects. 8. Quicker recovery from surgery. 9. If weight loss is not satisfactory, it can be converted to gastric bypass surgery.
