Gastric Bypass Beats Banding for Weight Loss

By    |   Friday, 26 September 2014 02:25 PM

Gastric bypass surgery is more effective than gastric banding for long-term weight loss, controlling Type 2 diabetes, and lowering blood pressure and cholesterol levels, according to a new review of studies.
 
The analysis, by the University of Texas Southwestern Medical Center surgeons, examined nearly 30 long-term studies comparing the two types of bariatric weight-loss surgeries.
 
The review, published in the Journal of the American Medical Association, found individuals undergoing gastric bypass operations lost more weight — an average of 66 percent of their excess weight — compared to 45 percent for those undergoing gastric banding procedures.
 
In addition, more than two-thirds of bypass patients with Type 2 diabetes saw remission of the disease, compared to less than a third of gastric band patients. Nearly half of patients (48 percent) with hypertension reported remission after two years with bypass, compared to less than a fifth (17 percent) for those undergoing gastric band procedures. And bypass also improved hyperlipidemia, characterized by high levels of cholesterol, triglycerides, and lipoproteins in the blood. About 60 percent of bypass patients reported remission in the studies, compared to about 23 percent of gastric band patients.
 
“We know gastric bypass brings more weight loss success and relief of commonly associated illness versus gastric band at one year after surgery,” said Nancy Puzziferri, M.D. “We now have the best evidence available telling us this outcome continues to be true even up to five years after surgery. We also know these procedures maintain their safety profile long-term.”
 
An estimated 120,000 bariatric procedures are performed annually in the U.S. Worldwide, gastric bypass accounts for about 47 percent of weight loss procedures, while gastric bands account for about 18 percent.
 
Gastric bypass, known as Roux-en-Y surgery, is the gold standard of weight-loss procedures. Surgeons create a smaller stomach pouch and reroute food to bypass part of the small intestine.

Gastric band procedures install an inflatable band around a portion of the stomach that can be adjusted to limit food intake.
 
After both procedures, patients feel fuller more quickly, and therefore eat less and consume fewer calories.
