Laparoscopic Gastric Bypass
The stomach is divided into two parts while the smaller part is only around 30ml which is anastomosed to a loop of small bowel that has bypassed the digestive juices for around 75-150cm. Weight loss is achieved by reducing the amount of food intake and bypassing part of the intestine in which nutrients are absorbed. The average weight loss and DM control is superior compared to the sleeve gastrectomy. On the other hand, complication rate including leakage is also higher which can go up to 2%. Patients are also required to take life-long vitamins and mineral supplements after the surgery. The expected weight loss at 2 years is around 70%.
