One anastomosis duodeno-ileal switch (SADI-S) or Stomach Intestine Sparing Surgery – known as SIPS for short – is a procedure that involves a sleeve gastrectomy being performed along with surgery to reroute the small intestine.
SADI-S weight loss surgery produces malabsorption to effect weight loss. It also produces good control for diabetes – greater than 95% – and other obesity-related illnesses. This is a variation of the procedure called Duodenal switch surgery. Duodenal switch is a very effective technique to facilitate weight loss in obese patients. It has been performed globally for over two decades with good long-term outcomes.
The SIPS procedure on the other hand is relatively new. The SIPS procedure is like the mini- gastric bypass version of the duodenal switch. It is done with one anastomosis and relies on malabsorption with limited restrictive component. The restrictive aspect of this type of weight loss surgery involves the removal of more than two-thirds, roughly 70% of your stomach. This part of the surgery is irreversible since the stomach is being surgically removed unlike a gastric bypass where no part of the stomach is removed.
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.
Significant weight loss can be achieved using these procedures, in some cases in-excess of 80-90% of a person’s body weight can be lost if the correct lifestyle changes are adhered to post-surgery.
Patient’s suffering from diabetes can often see high remission rates.
There is very low incidence of dumping syndrome (see our blog on dumping syndrome).
Minimal risk of ulceration at the new joint (anastomosis).
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.
This procedure does require close, long term follow up.
Fat malabsorption can result in frequent loose stools, abdominal cramping, and foul-smelling flatulence.
