Perth Weight Loss Surgery
Weight loss surgery, otherwise known as bariatric surgery, are a group of individual procedures, that, as stand-alone surgical procedures, help obese patients achieve a certain degree of weight loss. Many studies indicate that these procedures can be the catalyst for significant long-term weight loss. This is particularly the case with individuals considered to be ‘morbidly obese’
The types of procedures that fall under bariatric, or weight loss surgeries, are gastric band procedures; which involve surgically reducing the size of the stomach. Sleeve gastrectomy’s – the surgical removal of a section of the stomach or gastric bypass surgeries, where the small intestine is re-routed.
All of these procedures promote weight loss because they reduce the sensation of feeling ‘hungry’ by shrinking the volume of the stomach in some way. This triggers messages to the brain, making it ‘think’ you are full (because you are) when you have in fact consumed less food than you normally would.
The resultant ‘less intake’ of energy from your body’s perspective means, that with some basic lifestyle modifications, (like low-intensity walking each day) you will burn more energy than you ingest – and thus lose weight as the body seeks to burn its fat stores to provide you that energy.
This was the most common bariatric operation done in Australia a few years back. This has gradually declined in use due to high long term revision surgery and complication rate. This still has some role for certain patients.

The gastric bypass can be the traditional Roux en Y gastric bypass or the Single anastomosis gastric bypass also know as Omega loop/ mini gastric bypass. The decision to choose one surgery over the other depends on various factors including presence of reflux, previous surgery etc. The Roux en Y gastric bypass has been around for a long time and has good data of long term outcomes as compared to the Mini gastric bypass.
This procedure permanently reduces the volume of the stomach to approximately 15% of its original size. The traditional shape of the stomach is altered by removing the curved area, resulting in a more tubular shape.
This decrease in volume causes feelings of satiety to occur after less food has been consumed by the patient.
What is it?
An adjustable silicon band that sits around the upper part of your stomach forming a small pouch. This restricts the amount you can eat and produces early satiety.
- Doesn’t involve dividing or removing any part of your stomach or intestine
- 40 to 60% excess weight loss
- 15 to 30% patients will need some form of revisional surgery
- Reduced quality of eating
- Band slippage or erosion
- Access port flipping
- Oesophageal dilatation
What is it?
A weight loss procedure that has been tried and tested for over 40 years. It’s a procedure where the stomach is partitioned to a smaller size and small bowel is re-routed to this new gastric pouch. In the banded gastric bypass a fixed silastic ring is placed around the gastric pouch.
- Long standing information and results
- 80 to 90% excess weight loss
- Up to 90% diabetes control
- Good control of reflux
- Risk of ulcer in the anastomosis
- Dumping syndrome
- Internal hernia risk
A procedure where the stomach is formed into a narrow tube and remainder of the stomach is removed.
- Provides good quality of eating
- 50 to 60% excess weight loss in the long run
- 70 to 80% diabetes control
- Continuity of gastrointestinal tract is maintained
- if complication like a leak from staple line occurs its difficult to manage
- Gastric sleeve dilatation over time
- May cause reflux
This is when a previous bariatric operation such as a band needs to be revised due to complication or intolerance or weight regain.
A comprehensive assessment is done to assess the problem and various treatment options to address it will be provided. For example conversion of a gastric band to gastric bypass or sleeve gastrectomy based on underlying problem.
The SIPS procedure is like the mini- gastric bypass version of the duodenal switch. It is done with one anastomosis and relies on malabsorption as well.
This procedure is relatively new with not much long term data.
