SADI-S

The single anastomosis duodenal-ileal bypass with sleeve gastrectomy, referred to as the "SADI-S", is the most recent procedure to be endorsed by the American Society for Metabolic and Bariatric Surgery (ASMBS). While similar to the biliopancreatic diversion with duodenal switch, is technically simpler and takes less time to perform as there is only one surgical bowel connection.

​

The operation starts the same way as the sleeve gastrectomy, making a smaller tube-shaped stomach. The first part of the small intestine is divided just after the stomach. A loop of intestine is measured several feet from its end and is then connected to the stomach (this is the only intestinal connection performed in this procedure).

​

How does it work?

​

When the patient eats, food goes through the pouch and directly into the latter portion of the small intestine. The food then mixes with digestive juices from the first part of the small intestine. This allows enough absorption of vitamins and minerals to maintain healthy levels of nutrition. This surgery offers good weight loss along with less hunger, more fullness, blood sugar control and diabetes improvement.

​

Advantages

​

• Highly effective for long-term weight loss and remission of type 2 diabetes.

• Simpler and faster to perform than gastric bypass or biliopancreatic diversion with duodenal switch.

• It is an alternative as an alone surgical procedure for morbidly obese patients and an adequate option as a first step for high-risk patients.

• Highly effective as a revisional procedure for patients who already had a sleeve gastrectomy and is seeking further weight loss, and may be an excellent option after other failed bariatric procedures.

​

What to expect?

• Weight loss ranges from around 20% (excess weight) in the first 3 months up to nearly 100% after 2 years.

• Metabolic results are excellent, allowing remission of related diseases such as diabetes, dyslipidemia and hypertension.
