SADI-S Surgery

Single anastomosis duodenal-illeal bypass with sleeve gastrectomy (SADI-S) is a surgical procedure that can help treat those who have weight-related disease. This is one of the bariatric surgery options available at The University of Kansas Health System to help you lose weight and reach your health goals.

Single anastomosis duodenal-illeal 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. While similar to BPD-DS, the SADI-S is simpler and takes less time to perform as it requires only 1 surgical bowel connection.

SADI-S is a type of bariatric weight-loss surgery for people who need to reduce their weight and improve obesity-related health problems.

You will receive an evaluation to determine if SADI-S surgery is right for you. To be a candidate, you must be morbidly obese and be healthy enough to tolerate surgery. Those who have comorbid conditions like diabetes, are good candidates as well. Your physician will talk to you about which type of bariatric surgery is right for you.

After surgery, any food eaten goes through a smaller tube-shaped stomach 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.

Benefits include:

• Highly effective for long-term weight loss and remission of type 2 diabetes
• Simpler and faster to perform (1 intestinal connection) than gastric bypass or BPD-DS
• By shortening the path that food travels through in the intestine, fewer calories are absorbed. This combination of restriction and malabsorption creates a rapid weight loss.
• Excellent option for someone who already had sleeve gastrectomy and is seeking further weight loss

Risks include:

• Not reversible and may results in post-surgery complications for some people
• Requires strict compliance with your physician and care team’s recommended diet and vitamin supplementation since vitamins and minerals are not absorbed as well as after sleeve gastrectomy
• Newer surgery with only short-term outcome data
• Potential to worsen or develop new-onset reflux
• Risk of looser and more frequent bowel movements

The operation starts the same way as the sleeve gastrectomy, making a smaller tube-shaped stomach pouch. The first part of the small intestine is divided just after the stomach. A loop of the 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.

SADI-S surgery requires general anesthesia. After the surgery, you will spend 1 night in the hospital. Your diet will start with liquids, and you will then transition to soft foods until your body can adjust to solid foods again. Initially, you will feel full very quickly after eating a small amount of food.
