Bariatric Surgery for the Reduction of cArdioVascular Events Feasibility Trial

Although there may be slight variation by centre, Gastric Bypass generally involves creation of a 30-50 cc stomach pouch, which is anastamosed with a Roux limb of jejunum 75-100 cm in length and a biliary limb of 20-30 cm in length. The operation creates a small gastric pouch, with nutrients bypassing the duodenum and proximal jejunum. Sleeve Gastrectomy involves decreasing the size of the stomach to approximately 15% of its original size by resecting a large portion of the stomach along the greater curvature.
