Roux-en-Y Gastric Bypass Surgery

Roux-en-Y gastric bypass is the most commonly performed weight loss surgery. This form of bariatric surgery helps many patients successfully address obesity and obesity-related health issues.

The Roux-en-Y procedure is both restrictive and malabsorptive. This means that a smaller stomach pouch is created to restrict the amount of food consumed, creating the sensation of fullness sooner than a person otherwise might. The malabsorptive aspect of the procedure means fewer calories are absorbed through the small intestine. This two-pronged approach helps many people lose weight and keep it off for the rest of their lives.

How the Roux-en-Y Procedure Works

After the necessary steps are taken in preparation for bariatric surgery, the surgeon begins the procedure and sections off a portion of the stomach with special surgical staples. This section will create the new stomach pouch, which is about the size of one's thumb. This restrictive approach allows patients to consume less food while still experiencing the sensation of fullness.

After the stomach pouch is created, the small intestine is bisected. The lower part of the small intestine is then attached to the new stomach pouch. Taking this step means food passed through the stomach pouch will bypass both the lower stomach and the top of the small intestine, known as the duodenum. This malabsorptive approach is highly effective as the majority of the calories absorbed by the body are absorbed through the duodenum, and that is bypassed.

In order to deliver essential digestive fluids produced in the top part of small intestine (which is now bypassed in the digestive process), this section of small intestine is then reattached to the lower part of the small intestine. The connection resembles a "Y," which is the basis for the unique name given this procedure.

All surgeries pose some risk, and Roux-en-Y gastric bypass is no exception. Even when performed by a competent surgeon, the possible risks associated with Roux-en-Y surgery can be serious and life threatening. Your surgeon will help you carefully weigh potential risks with potential benefits of Roux-en-Y surgery so you can make the decision that is right for you.

Laparoscopic Roux-en-Y Gastric Bypass Surgery

In some cases, Roux-en-Y gastric bypass surgery can be performed laparoscopically. As a minimally invasive technique, laparoscopic Roux-en-Y surgery involves the use of a number of very small incisions. A surgical instrument called a laparoscope, which is equipped with a small video camera, is inserted through one of these incisions. The other necessary surgical instruments are inserted through the other small incisions. Images from the camera are then displayed on a monitor and are used by the surgeon to navigate during the surgery. The laparoscopic method of Roux-en-Y gastric bypass surgery is not right for everyone. Some may learn that the "open" Roux-en-Y technique, although more invasive, maybe be better suited for them. Your surgeon will help you determine your weight loss surgery options.
