Banded Roux-en-Y Gastric Bypass (BRYGB) is a surgical procedure that can be performed by a miniinvasive (Video)surgical method. The procedure reduces food intake AND reduces the absorption of nutrients from the food. Absorption of nutrients is limited because part of the intestines is bypassed and not used. The volume of the stomach pouch by LBRYGB is between 15 and 25 ml. The junction between the stomach pouch and small bowel is controlled by a (restricted by a?) silastic ring (GaBP Ring). The alimentary limb (AL, green in the image) in LBRYGB is 120 – 150cm long, the biliopancreatic limb (BPL, pink in the image) consists of 50 cm of small intestine.
