Gastric bypass is a combination procedure using both restrictive and malabsorptive elements. With this surgery, first the stomach is stapled to make a smaller pouch. Then most of the stomach and part of the intestines are bypassed by attaching (usually stapling) a part of the intestine to the small stomach pouch. The result is that you cannot eat as much and you absorb fewer nutrients and calories.
Advantages of gastric bypass
Rapid initial weight loss
Minimally invasive approach is possible
Longer experience in the United States
Higher total average weight loss reported than with LAP-BAND or VBG
Disadvantages of gastric bypass
Cutting and stapling of stomach and bowel are required
The LAP-BAND system adjustable gastric banding procedure restricts the amount of food the stomach can hold by placing an inflatable silicone band around the upper part of the stomach. The new, small upper stomach pouch limits the amount of food that can be consumed at one time, and a narrowed stomach outlet increases the time it takes for the stomach to empty. The subsequent reduction in food intake results in weight loss.
Advantages of adjustable gastric banding
Lowest mortality rate
Least invasive surgical approach
No stomach stapling or cutting, or intestinal re-routing
