Gastric bypass procedures (GBP) are any of a group of similar operations that first divides the stomach into a small upper pouch and a much larger lower "remnant" pouch and then re-arranges the small intestine to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different GBP names.
