SADI-S (Single Anastomosis Duodenal-Ileal Switch) is an advanced type of bariatric surgery that combines a sleeve gastrectomy with a duodenal-ideal bypass.
In the first part of the procedure, a sleeve gastrectomy is performed by removing a large part of the stomach, leaving a smaller, tube-like stomach. The stomach sleeve is then connected to the end of the small intestine bypassing most of the small intestine which cuts down on calorie absorption.
The benefits of SADI-S
The many benefits of SADI-S are as follows :
- Significant Weight Loss: SADI-S offers substantial long-term weight loss by combining a reduction in stomach size with a rerouting of the intestines, limiting calorie absorption.
- Improved Metabolic Health: The procedure is effective in improving or resolving conditions such as type-2 diabetes, high blood pressure, and high cholesterol.
- Better Nutrient Absorption: Compared to other malabsorption surgeries, SADI-S carries a lower risk of nutritional deficiencies, as more of the small intestine remains intact.
- Single Anastomosis: The surgery involves only one connection, or anastomosis, between the stomach and intestines, which reduces the risk of complications.
- Durable Results: SADI-S provides durable and sustained weight loss results with a lower likelihood of regaining weight compared to other bariatric procedures.
Candidates for SADI-S
Ideal candidates for SADI-S are people :
- With a Body Mass Index (BMI) of 40 or higher.
- With a BMI of 35 or above with obesity related serious health conditions such as type-2 diabetes or heart disease.
- Who have tried and failed to lose weight through diet and exercise alone.
- Who are ready to commit to lifelong lifestyle changes such as healthy diet and physical activity.
As with all surgical procedures, SADI-S is not without risks such as nutritional deficiencies and surgical problems. A proper assessment by a healthcare provider is necessary.

Our Surgeons
The steps involved in a SADI-S (Single Anastomosis Duodenal-Ileal Switch) bariatric surgery are as follows:
- Anesthesia: The patient is placed under general anesthesia to ensure they are unconscious and pain-free during the surgery
- Laparoscopic Access: Small incisions are made in the abdomen, and a laparoscope (a thin tube with a camera) along with surgical instruments are inserted.
- Sleeve Gastrectomy: The surgeon removes about 80% of the stomach, creating s smaller sleeve-shaped stomach that limits food intake.
- Duodenal Transection: the duodenum (the first part of the small intestine) is cut just below the stomach, leaving a small portion connected to the stomach.
- Intestinal Rerouting: The lower part of the small intestine (ileum) is brought up and connected to the remaining duodenum creating a single anastomosis (connection). This reduces the amount of intestine where calories are absorbed.
- Closure: The surgeon removes the laparoscopic instruments and closes the incisions.
- Recovery: The patient is moved to a recovery area to be monitored as they wake up from anesthesia. The hospital stay is typically 2-3 days followed by a recovery period with a specific diet and lifestyle adjustments.
