SADI-⁠S Surgery in Toronto

SADI-⁠S: a sleeve and a new route

SADI-⁠S starts with a gastric sleeve, then adds a single connection that sends food to a lower loop of the intestine. Food and digestive juices meet later, which can affect hunger and blood sugar more than a sleeve alone. Results vary.

The route of food and digestive juices, before and after SADI-S Before surgery, bile and digestive juices join food in the duodenum, and both travel the whole small intestine together. After SADI-⁠S, food goes from the sleeve through a single new connection straight to a lower loop of intestine; the juices travel the long loop alone and meet the food only for the last stretch before the large intestine.

Six steps, one connection

Scroll through the operation as Dr. Schofield explains it: first a sleeve, then the duodenum is divided and joined to a loop of intestine. Scroll back to see any step again.

  1. 01

    Your stomach and intestine

    Food passes from the stomach into the duodenum, where bile and digestive juices join it.

  2. 02

    First, a sleeve

    SADI-⁠S starts with a sleeve gastrectomy: the outer 80% of the stomach is removed.

  3. 03

    The duodenum is divided

    Just past the pylorus, the duodenum is divided and its lower end closed.

  4. 04

    A loop of intestine

    A loop of the lower small intestine is brought up to meet the duodenum.

  5. 05

    One single connection

    A single connection joins them. Food bypasses a long stretch of intestine, which can affect hunger and blood sugar.

  6. 06

    The new path

    Food travels through the sleeve straight into the loop, and meets digestive juices further down.

Vitamins and checks, for life

Because food meets the digestive juices later, the body absorbs less of some nutrients. That is part of how SADI-⁠S works, and why your follow-⁠up matters even more.

Your dietitian sets your supplements, and bloodwork at 6 months and then every year shows how you are doing. The 360 SmartTrack app reminds you, and your nurse is your first call with any question.

Questions about SADI-⁠S

What people ask before choosing SADI-⁠S. Dr. Schofield goes through all of it with you at your consultation.

Still wondering? , or ask the assistant in the corner.

  • 01What does SADI-⁠S stand for?

    Single anastomosis duodeno-ileal bypass with sleeve gastrectomy. In plain words: a sleeve, plus one connection between the duodenum and a lower loop of the small intestine.

  • 02How is SADI-⁠S different from a gastric bypass?

    In a gastric bypass, a small pouch is made at the top of the stomach and joined to the intestine, and the pylorus is bypassed. In SADI-⁠S, the stomach becomes a sleeve, the pylorus is kept, and there is one connection instead of two.

  • 03Can a sleeve be converted to SADI-⁠S later?

    Sometimes. If you already have a sleeve, SADI-⁠S can be done as a second step. Your surgeon reviews your history and your health first.

  • 04Will I need more vitamins than after a sleeve?

    Usually, yes. SADI-⁠S reduces how much of some nutrients the body absorbs, especially the fat-soluble vitamins A, D, E and K. Daily supplements and regular bloodwork are part of your plan for life.

  • 05Does SADI-⁠S help with type 2 diabetes?

    SADI-⁠S is often discussed for people with type 2 diabetes because it can affect blood sugar more than a sleeve alone. How it affects you depends on your health, and your surgeon explains what is realistic for you.

  • 06Will my digestion change?

    Some people have more frequent or looser bowel movements, especially after fatty foods. Your dietitian helps you adjust what you eat, and your team checks in regularly.
