MGB Gastric Bypass:
The MGB (Single Anastamosis Gastric Bypass) was first used in America 16 years ago. It was deemed to be a safe, rapid and effective bariatric operation that yielded excellent results. As it has grown in popularity the worldwide number of procedures has increased significantly.
REY Gastric Bypass:
The Roux-en-Y gastric bypass procedure involves creating a stomach pouch from a small portion of the stomach and attaching it directly to the small intestine, bypassing a large part of the stomach and duodenum. Not only is the stomach pouch too small to hold large amounts of food, but by skipping the duodenum, fat absorption is substantially reduced.
