Although most of them have not been used due to various problems, with the advancement of medical technology, some previously abandoned procedures may have new opportunities to be realized. One of them is the “resurrection” of the jejunostomy through the fusion of procedures. The jejunostomy is known as the original weight loss surgery, simple jejunostomy can effectively reduce the absorption of the body, but because it has been impossible to control the length of the part of the intestine that is left open, the result of this surgery is either the distance is too short to achieve weight loss, and the distance is too long to cause serious malnutrition, which is dangerous to health. Therefore, simple jejunostomy is generally not recommended, until someone later combined sleeve gastric surgery with jejunostomy, and the weight loss results obtained were better than the results of the single procedure before the combination, and from then on, sleeve gastric jejunostomy emerged. Although sleeve gastrojejunostomy has excellent results, it is relatively more difficult to perform the surgery. According to the data of domestic bariatric surgery cases, sleeve gastric surgery is basically the most popular choice, because a single gastric reduction surgery is the simpler of the many procedures. Therefore, in order to do the sleeve gastrojejunostomy with better results, it is necessary to find a better hospital and doctor, because weight loss surgery can affect the safety and results of the surgery due to the experience and skills of the doctor, which is more prominent for difficult surgeries.
