The Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S) is an advanced bariatric surgery designed to promote significant weight loss and metabolic improvements. This procedure combines two key components: a sleeve gastrectomy, which reduces stomach size, and a duodeno-ileal bypass, which alters the digestive process to limit calorie absorption. The SADI-S shares similarities with the standard duodenal switch but is a more streamlined procedure, requiring less time to complete since it involves only one surgical bowel connection.

How Its Done
The SADI-S procedure begins similarly to a sleeve gastrectomy, where a large portion of the stomach is removed, leaving behind a smaller, tube-shaped stomach. Next, the upper section of the small intestine is separated just beyond the stomach. A segment of the lower small intestine is then measured and connected directly to the stomach, creating a single connection point, which simplifies the procedure compared to other bypass surgeries.
After surgery, food moves from the newly shaped stomach directly into the lower part of the small intestine, bypassing a portion of the digestive tract. Once there, it combines with digestive enzymes from the bypassed section, ensuring adequate absorption of essential vitamins and minerals. This procedure not only supports significant weight loss but also helps reduce hunger, increase feelings of fullness, regulate blood sugar, and improve or even resolve type 2 diabetes.
SADI-S is an effective procedure for long-term weight loss and type 2 diabetes remission. It is simpler and faster than gastric bypass or BPD-DS, making it a good option for those needing additional weight loss after a sleeve gastrectomy. However, it requires lifelong vitamin supplementation due to reduced nutrient absorption. As a newer procedure, long-term data is limited, yet some patients may experience acid reflux or more frequent bowel movements.

Potential Risks
Before considering the SADI-S, it is important to become familiar with the potential risks of bariatric procedures. Risks vary based on the health of the patient.
- Minor Complications
- Major Complications
Minor Complications
UNCOMMON AND CAN BE MANAGED FAIRLY EASILY
- Minor wound or skin infection
- Excess / loose skin
- Vomiting or nausea
- Acid reflux (heartburn)
- Changes in bowel habits like constipation, diarrhea, bloating, cramping, or gas
- Development of gallstones or gallbladder disease
- Nutritional deficiencies as a result of food bypassing the stomach
Major Complications
COMPLICATIONS COULD RESULT IN RE-OPERATION
- Internal bleeding
- Intestinal obstruction
- Blood clots in the legs or lungs
- Internal hernia
- Perforation of stomach/intestine or leakage
SADI-S FAQs
Should I get the SADI-S or the duodenal switch?
The best choice depends on your individual health goals, medical history, and your surgeon’s recommendation. The SADI-S is a simpler procedure with one intestinal connection, reducing surgical risks while still providing significant weight loss and metabolic benefits. The traditional Duodenal Switch (BPD-DS) may lead to slightly greater weight loss but comes with a higher risk of nutritional deficiencies due to increased malabsorption. Your surgeon can help determine which option is best for you.
How much weight will I lose after SADI-S surgery?
Weight loss after SADI-S varies by individual, but on average, patients can expect to lose 70-85% of their excess body weight within the first 12-18 months after surgery. Factors such as adherence to dietary guidelines, exercise, and overall health can influence results. One study compared the SADI-S and sleeve gastrectomy and found that SADI-S resulted in significantly more weight loss, with an average excess weight loss of 88% compared to 65% for sleeve gastrectomy.
Who is a good candidate for SADI-S surgery?
SADI-S is typically recommended for individuals with a BMI of 40 or higher, or those with a BMI of 35 and above who have obesity-related health conditions such as type 2 diabetes. It may also be an option for patients who previously had a sleeve gastrectomy and need additional weight loss. Your surgeon will assess your overall health and weight to determine if SADI-S is the right choice for you.
