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.

It has gradually replaced the traditional open surgery and is now commonly used in bariatric surgery in the United States. One of the techniques.
