SADI-S

SADI-S is short for Single Anastomosis Duodenal-Ileal Bypass with Sleeve Gastrectomy.   It is the latest bariatric procedure to be endorsed by the American Society for Metabolic and Bariatric Surgery.  SADI-S is a simpler version of the Biliopancreatic Diversion with Duodenal Switch, with only one surgical bowel connection instead of two.  Sage Bariatric Institute surgeons have been performing SADI-S successfully for over 5 years.

The SADI-S Bariatric Procedure

1. A sleeve gastrectomy is performed, removing about 80% of the stomach to create a smaller tube or sleeve-shaped stomach.
2. Just after the stomach, the first part of the small intestine is divided.
3. A loop of intestine, at a point approximately 2/3 of the way down, is then connected to the stomach.

How it Works

• Food passes through the sleeve directly into the small intestine, bypassing approximately 2/3 of the small intestine.  Digestive juices/enzymes from the first part of the small intestine mix with the food for digestion as it continues down the gastrointestinal tract, allowing for absorption of nutrients.
• The smaller stomach decreases how much food you can eat at a time, and bypassing much of the small intestine significantly reduces your absorption of calories.
• The changed food pathway alters hormones in the gastrointestinal tract that decrease hunger and increase fullness.   SADI-S thus promotes significant weight loss.
• SADI-S also results in significantly improved blood sugar control and diabetes improvement, and in many patients may result in remission of type II diabetes.

Advantages

• Highly effective for long-term weight loss and remission of type 2 diabetes
• Simpler and faster to perform (one intestinal connection) than gastric bypass or BPD-DS (biliopancreatic diversion with duodenal switch)
• Lower risk of ulcers and bile reflux than some procedures
• Excellent option for a patient who already had a sleeve gastrectomy and is seeking further weight loss

Disadvantages

• Newer procedures have less long-term data.  Many published studies demonstrate SADI-S as a safe and very effective weight loss surgery, but more data is needed.
• Advanced technical experience is required. Sage Bariatric surgeons have been performing this procedure for over five years, and they have performed over 18,000 bariatric surgeries.  They are experts in this field and in the modification of this complex anatomical area.

Weight Loss and Return to Work

The SADI-S is accomplished laparoscopically (minimally invasive) in most cases. Patients usually go home after 1-2 nights in the hospital, and usually go back to work around 2 weeks after surgery. Results vary from patient to patient, but on average patients lose 87% of their excess weight (38% of total body weight).

Vitamins and Supplements

Long term bariatric follow up and long term supplement intake are important for all bariatric operations, but vitamins are especially important with the SADI-S. Patients who don’t take the right supplements incur significant risk of medically serious conditions due to vitamin deficiencies.  These are easily avoided by taking bariatric-specific vitamins and having your vitamin levels checked with us once a year.

As with all bariatric surgeries, it is important to choose a surgeon at a high-volume program with extensive experience in both surgical technique as well as long-term management and support of patients.
