Gastric bypass surgery

Roux-en-Y gastric bypass (referred to as RYGB) is a surgery that changes the structure of the intestine and closes most stomach functions. Surgery divides the patient's stomach into upper and lower parts. Only 1 / 6-1 / 10 of the original stomach is used to hold food, and then a "fork" is opened at the incision of the small stomach, followed by a section of the small intestine that is rearranged. The position of the small intestine changes the way that food passes through the digestive tract, slows the rate of gastric emptying, shortens the small intestine, reduces absorption, and thus achieves the purpose of weight loss. Since the operation has good results and relatively few complications, it has been respected as one of the most effective procedures for the treatment of obesity since the 1990s, and it is also the most popular operation method of diabetes surgery. The laparoscopic Roux-en-Y gastric bypass surgery (LRYGB for short) has less trauma, faster recovery, lower perioperative complication rate, and is safe and effective. It has gradually replaced the traditional open surgery and is now commonly used in bariatric surgery in the United States. One of the techniques.
