Single anastomosis stomach-ileal bypass with sleeve gastrectomy (SASI-S)

What is SASI-S?

A single anastomosis stomach-ileal bypass with sleeve gastrectomy (SASI-S) combines the benefits of a gastric sleeve (where a section of the stomach pouch is removed) and a gastric bypass.

 

Here’s what the lengthy name means:

How is SASI-S different from a gastric sleeve?

SASI-S involves a gastric sleeve operation but the food stream is only partially diverted from the proximal small bowel. The remaining part of your stomach is completely removed in a SASI-S whereas it remains in place (though sealed off) after a gastric sleeve.

What are the benefits of SASI-S?

A SASI-S combines two different approaches to surgical weight loss. You’re reducing the size of your stomach and reducing your calorie absorption.

 

You’re also less likely to be hungry because your body reduces intestinal brake hormones when undigested food hits the distal small bowel.

 

That makes SASI-S both a restrictive treatment and a hormonal one – the best of both worlds.

 

Studies show that, when compared to other weight loss surgeries, SASI-S:

A recent retrospective study of over 600 SASI-S patients in 7 countries found that, after 12 months:

What are the disadvantages of SASI-S?

There are risks involved with any surgery, such as bleeding, clotting, reacting to the anaesthetic or developing an infection.

Will a SASI-S help me lose weight and keep it off?

A SASI-S aims to help you lose weight by making your stomach smaller so you can’t eat as much and by changing the way your hormones regulate your sense of being hungry or full. When followed up after 12 months, many patients have lost a significant amount of excess weight.

 

We can expect that, like the gastric sleeve and gastric bypass procedures a SASI-S is based on, you’re likely to maintain long-term weight loss if you’re able to make lasting lifestyle changes after your operation.
