The mini-gastric bypass is a novel surgical procedure that creates a tube stomach, which is long and narrow and has a small exit point, so it empties at a slower rate. A lower loop of the small intestine is brought up and joined to this tube stomach. This means the stomach empties directly into a lower part of the small intestine. The largest part of the stomach and the first section of the small intestine are completely bypassed. They are, however, connected lower down, ensuring that gastric juices, gall and digestive enzymes from the pancreas do reach the small intestine, where they are needed to ensure the food is properly digested.
