SASI-S Surgery

What is SASI-S surgery?

Single Anastomosis Stomach-Ileal Bypass (or SASI-S Bypass) is a combination of a sleeve gastrectomy and an intestinal bypass. To begin with, a sleeve gastrectomy is performed, followed by the joining of the bottom part of the stomach to the distal part of the small intestine. The length of the bypass is determined by the required amount of weight-loss.

After this procedure, roughly half of the food will bypass the first part of the small intestine, which will then causes a reduction in the absorption of fats and sugars. Along with this, the slow digestion of the food In the small intestine stimulates the release of intestinal hormones, which tell the brain to stop eating. This means you eat less, resulting in weight loss.

ADVANTAGES OF SASI-S SURGERY

Many studies show that SASI-S bariatric surgery can provide greater weight loss when compared to a standard sleeve gastrectomy, or a traditional gastric bypass.

Reduces hunger
Less risk of nutritional deficiencies
Benefits of the gastric sleeve and gastric bypass
- Good quality eating
- Continuity of gastrointestinal tract is maintained
- 70 – 90% diabetes control
Access to bile duct remains (if in the future gallstones need to be removed)
Less risk of an internal hernia

DISADVANTAGES OF SASI-S SURGERY

Increased risk of bile reflux into the stomach
Weight loss may be less than SADI-S or One anastomosis gastric bypass
Risk of an ulcer forming at the join between the stomach and the small intestine
Relatively new operation with limited long term outcomes

This procedure can be reversed back to a gastric sleeve simply by stapling across the join.

Frequently Asked Questions

Is SASI-S surgery right for me?

It is recommended that a consultation with Mr Siva Gounder at one of our surgeries based in Perth be the first step should you be considering this type of surgery.

Mr Gounder has performed many of these surgeries and can explain in detail the advantages and the disadvantages of such a surgical procedure.
Is SASI-S surgery safe?

There are risks with any type of surgery, these include infection, risk of leaks, and malabsorption.

There is a natural increase in malabsorption since this is the intention of the procedure. The body is limited in the amount of vitamins, minerals and calories it can absorb from food. So whilst it limits the ‘bad’ absorption, it also limits the ‘good’ too.

Because of this fact, there is an increased requirement of dietary supplements, such as vitamins and proteins that need to be taken to reduce long term nutritional deficiencies.

Fat malabsorption can result in frequent loose stools, abdominal cramping, and foul-smelling flatulence.
How much weight can you lose with SASI-S surgery?

It is possible to achieve a loss of up to 80-90% excess weight, however specific results will differ for each individual. Please contact Mr Gounder for a consultation to find out how much weight you could lose.
Preparing for SASI-S surgery

It is important follow the specific guidelines provided to you prior to your surgery, this includes not eating or drinking anything the night before so the stomach is empty to minimalise surgical risks.

You will be advised of any specific changes to medication and diet in the days or weeks before surgery if necessary.
What to expect after SASI-S surgery?

Following your surgery you will spend some time recovering, and be administered pain medication. For the first few weeks you will follow a liquid diet. You will be given a specific diet plan to follow and it is important you follow this closely.

You will need to take vitamin and mineral supplements post surgery.
Clinic follow up

You will need to have a follow up after your procedure to monitor your specific individual health needs and progress.
