Roux-en-y gastric bypass is a restrictive-malabsorptive operation for weight loss. It is the second most common procedure in Australia, and around the world, and in some countries, it is the most common type of weight loss surgery.
Gastric bypass is usually performed via laparoscopic (Keyhole or robotic techniques. The general steps of Roux-en-Y-gastric bypass (RYGB) include 1) gastric pouch creation, 2) creation of biliopancreatic limb, 3) jejunojejunostomy creation, and 4) creation of gastrojejunostomy. This procedure induces weight loss through multiple mechanisms. The expected weight loss can be up to 80-85% of excess body weight, though individual results can vary. This procedure has a higher risk of diarrhoea, malnutrition and vitamin deficiencies. Therefore, patients must follow all of our team's instructions.
