Roux-en-Y Gastric Bypass
The Roux-en-Y gastric bypass is the most common form of weight-loss surgery and has been performed for almost 50 years. In a Roux-en-Y gastric bypass, a small pouch about the size of an egg is created at the top of the stomach using surgical staples or a plastic band. This pouch effectively acts as the patient’s “new” stomach.
The smaller stomach is connected directly to the middle portion of the small intestine, bypassing the rest of the stomach and the upper portion of the small intestine. No stomach or intestine is removed during surgery.
The new connection between stomach pouch and intestine restricts intake and changes the way food is digested. The new, smaller stomach pouch allows the patient to feel full with much smaller meals.
This procedure can be done by making an incision in the abdomen (an open procedure) or by making a smaller incision and using specialized instruments and a camera to guide the surgery (laparoscopic approach). Our surgeons use the laparoscopic approach whenever possible. This minimally invasive procedure allows for fewer surgical complications, a smaller chance of infection, and a shorter recovery time for patients.
The gastric bypass is a proven way for patients to achieve rapid and sustainable weight-loss. It’s not uncommon for patients to lose between 40 and 100 pounds during the first three months after surgery. Patients will often continue losing weight at a steady rate up to two years after surgery, until they have reached their ideal body weight that they can sustain for the rest of their life.
