Roux-en-Y Gastric Bypass
The Roux-en-Y (RNY Gastric bypass) procedure is one of the best-understood bypass surgeries we have. It is performed now using keyhole surgery, so there is minimal scarring and a faster recovery time.
However, as with all surgeries, there are important side effects to consider, including the resulting malabsorption of nutrients afterwards. This means that careful lifestyle choices must be maintained to ensure good health for the years after surgery.
What is a Roux-en-Y Gastric Bypass?
A Roux-En-Y Gastric Bypass (RNY Gastric Bypass) is considered the gold standard operation in bariatric surgery. It has been performed by open surgery for fifty years and by keyhole surgery for thirty years.
As a result of this long history, we understand how the operation works very well. This includes the possible short, medium and long term risks, and its performance over an extended period of time.

Benefits of Roux-en-Y gastric bypass surgery?
The RNY Gastric Bypass surgery is extremely beneficial for controlling GERD (gastroesophageal reflux disease). It is arguably the best operation we have for this condition.
It leads to slightly better weight loss than a sleeve gastrectomy and has a much greater impact on diabetes.
The small bowel, in the area where it transitions from the duodenum to the jejunum, is dissected. The jejunum end of this dissection is attached to the bottom of the small gastric pouch, and then the duodenum end of the dissection is attached further down into the jejunum. This leads to a “Y” shaped configuration.
One end of the “Y” is sewn to the pouch, and the other end drains the digestive enzymes made by the pancreas and liver directly into the jejunum. This is where they are required for the digestion of food once it leaves the gastric pouch.
Disadvantages of a Roux-en-Y gastric bypass surgery?
The RNY Gastric Bypass, like any weight loss surgery, has a small failure rate when measured over an extended period of time. Weight gain may occur.
Our Perth patients often wonder if roux-en-y is reversible. It’s not, and the revision surgery options for the RNY Gastric Bypass are difficult and not as effective as we would like them to be.
One of the other disadvantages of the RNY Gastric Bypass is the resulting nutrient malabsorption. There is a reduced capacity of the remaining intestine to absorb nutrients from the food consumed. This may cause issues in people over an extended period of time, and can lead to other serious health concerns.
All patients who have had a bypass MUST take multivitamins and have regular follow up blood tests with their doctor, to monitor the levels of these micronutrients in your body.

About Obesity Surgery WA: Our 6 commitments
Taking surgery seriouslyWe know that entering into an operation is a big deal and we are very serious in getting the best outcome for you. We practice what is considered to be a world class standard. Our staff regularly attend national and international conferences and bring back what is the latest research and technology.
Running on timeOur Surgeons and all of our staff try their best to run on time. Although it's not always possible, our commitment is that we do our best. Your time is valuable and we respect that.
Readily availableOur surgeons (or at least one of them) are always available in a crisis. Some of them may provide you with a direct contact, but all are available through the hospital switchboard and happy to chat any time if there is a crisis.
An obsessive attention to detailWe do our best to not miss anything. Every stitch, every staple and every clip is applied to exactly where it needs to be with the greatest care possible.
Commitment to performing the best operation possibleNot all operations are the same and there a few extras that we do to make things better. We know that our results are better with the minimiser ring so we offer it to everyone. We know that reflux can be an issue so we try to tighten every oesophageal hiatus to make reflux control as good as possibly can be.
A commitment to new technologies
- We have brought in STRETTA into Western Australia, which we believe will revolutionise reflux management. (Have a look at the Stretta page for more information).
- SJOG Murdoch has just purchased a new DaVinci robot and we believe that this will allow us to do operations with keyhole surgery that previously needed a major laparotomy incision. Lynx is on the horizon and promises to also help manage reflux, we hope to have access to this in early 2020.
