About Roux-en-Y Gastric Bypass

A Roux-en-Y Gastric Bypass involves a surgical procedure for weight loss, performed under general anaesthesia and through a keyhole procedure. Roux-en-Y surgery was named after César Roux, the Surgeon who first described it. The  Y relates to the diagrammatical shape of the anastomosis (the technique to make a new connection when the Surgeon bypasses the gastrointestinal tract). So when the term Roux en Y (or Roux-en-Y) is used, we are referring to a Gastric Bypass Surgery.

When is a Roux-en-Y Gastric Bypass Used?

Gastric bypass surgery has been used as a common weight loss procedure for more than 40 years. In Australia, and also at Advance Surgical in Perth, it has become a more popular choice in recent years, particularly for patients with diabetes.

Your GP and your Bariatric Surgeon will determine if you are a candidate for weight loss surgery. Weight loss or bariatric surgery is known to significantly reduce other adverse health effects of obesity, such as high blood pressure, sleep apnea, and Diabetes Type 2.

How Does a Roux-en-Y Gastric Bypass Work?

The procedure is performed through keyhole surgery (Laparoscopy) and takes place under general anaesthesia. Your Surgeon will use the keyhole surgery instruments to staple the top of the stomach so it forms a small pouch: your new, smaller stomach separated from the rest of the stomach. The pouch is then joined to the small intestine, bypassing the first part of the intestine. A Roux-en-Y Gastric Bypass surgery generally takes 2-3 hours. 

Gastric Bypass or Sleeve Gastrectomy?

To determine the most suitable obesity surgery option for your circumstances, your Surgeon will discuss your options and your weight loss goals. To make use of weight loss surgery services you will also need a current GP referral.

In your consultation, our multidisciplinary team will advise you on the available options, on what to expect and how to prepare, and on potential risks and requirements post-surgery. As a team we will do everything we can to assist you on your weight loss journey.
