Roux-en-Y Gastric Bypass (RYGB)

Roux-en-Y gastric bypass (RYGB) is a weight-loss surgery that reduces the size of the stomach and restricts the amount of food a person can eat. This surgery also changes the way the body absorbs food and turns it into energy (metabolism). Fellowship-trained surgeons at our Bariatric and Metabolic Surgery Center have performed hundreds of these procedures. RYGB has changed the lives of many people who were unable to reach a healthy weight through nonsurgical methods.

Our surgeons use minimally invasive laparoscopic techniques whenever possible. As a result, patients recover faster and have reduced scarring after surgery.

What Is Roux-en-Y Gastric Bypass?

RYGB is a procedure in which doctors reduce the size of the stomach to a pouch about the size of an egg and attach it to the intestine. It is the most common surgical weight-loss procedure in the U.S. People typically lose 50 to 75 percent of their excess weight in the first 12 to 18 months after this surgery.

Because RYGB greatly reduces stomach size, you will need to eat smaller meals to prevent the pouch from stretching. However, you may find that hunger is greatly reduced because creating a smaller stomach helps regulate ghrelin, an appetite-stimulating hormone. In addition, because food now empties directly into the stomach, the way the body metabolizes food is different, and you may need to take vitamin supplements regularly.

To perform this surgery, one of our highly skilled surgeons:

  • Removes most of the stomach, leaving a pouch the size of an egg.
  • Brings up the roux limb of the small intestine and connects it to the pouch.

The surgery takes about 1 to 2 hours, and you can expect to spend about two and a half days in the hospital. The procedure is difficult to reverse.

A Minimally Invasive Approach

Our surgeons use laparoscopy, a minimally invasive surgical technique, in nearly all patients undergoing RYGB to reduce the risk of complications. To perform laparoscopic surgery, doctors make several small incisions in the abdomen, rather than the large incision used in open surgery. These small incisions provide access for surgical tools, including a laparoscope, a thin tube with a small camera to view the procedure.

Minimally invasive surgery promotes:

  • Faster healing
  • Faster return to normal activities
  • Less scarring
  • Lower risk of surgical complications
