Single Anatomosis Duodenal Switch
What Is Single Anastomosis Duodenal Switch (SADI-S)?
Single Anastomosis Duodenal Switch (SADI-S) is an advanced bariatric procedure that combines the benefits of a sleeve gastrectomy with an intestinal bypass to promote substantial weight loss and metabolic improvement. The procedure is considered one of the most effective surgical options for treating severe obesity and obesity-related diseases, particularly Type 2 diabetes.
At Chicago Metabolic & Digestive Surgery Center, Dr. Jihad Kudsi offers SADI-S as part of a comprehensive bariatric surgery program designed to help patients achieve meaningful, long-term weight loss and improved overall health.
How SADI-S Works
The procedure consists of two important components:
Sleeve Gastrectomy
The first step involves removing approximately 75–80% of the stomach, creating a smaller sleeve-shaped stomach that helps patients feel satisfied with smaller meals.
Intestinal Bypass
The second step involves connecting the duodenum to a lower portion of the small intestine using a single anastomosis (connection). This reduces calorie absorption and creates powerful hormonal changes that support weight loss and metabolic improvement.
Together, these mechanisms help patients:
- Eat less
- Feel full sooner
- Experience reduced hunger
- Absorb fewer calories
- Improve blood sugar regulation
Benefits of SADI-S
SADI-S has become an increasingly popular bariatric procedure because it combines excellent weight loss outcomes with a simplified surgical design.
Potential benefits include:
- Significant long-term weight loss
- Powerful metabolic effects
- Improvement or remission of Type 2 diabetes
- Improvement in high blood pressure
- Improvement in sleep apnea
- Improvement in high cholesterol
- Reduced hunger and appetite
- Enhanced quality of life
Many patients achieve substantial excess weight loss and experience improvement in obesity-related medical conditions within the first year after surgery.
Who May Be a Candidate?
SADI-S may be appropriate for patients who:
- Have severe obesity
- Have a BMI of 40 or greater
- Have a BMI of 35 or greater with obesity-related health conditions
- Have Type 2 diabetes or metabolic syndrome
- Have struggled to achieve lasting weight loss through non-surgical methods
- Are committed to lifelong follow-up and nutritional management
A comprehensive consultation with Dr. Kudsi helps determine whether SADI-S is the most appropriate procedure based on individual health goals and medical history.
SADI-S vs. Other Bariatric Procedures
Compared to gastric sleeve surgery, SADI-S generally produces greater weight loss and stronger metabolic effects because it includes both stomach reduction and intestinal bypass.
Compared to gastric bypass, SADI-S may provide:
- Greater long-term weight loss for selected patients
- Excellent diabetes control
- A single intestinal connection
- Preservation of the stomach's natural outlet valve (pylorus)
Dr. Kudsi works closely with each patient to determine which bariatric procedure best aligns with their health goals and medical needs.
Recovery After SADI-S
Most patients undergo surgery using advanced minimally invasive laparoscopic or robotic techniques.
Benefits of minimally invasive surgery may include:
- Smaller incisions
- Reduced postoperative discomfort
- Faster recovery
- Shorter hospital stay
- Reduced scarring
Patients follow a carefully structured postoperative nutrition plan and receive ongoing support throughout their weight loss journey.
Long-Term Nutritional Considerations
Because SADI-S affects nutrient absorption, lifelong vitamin and mineral supplementation is essential.
Patients require regular follow-up visits and laboratory monitoring to help ensure adequate nutrition and maintain long-term health after surgery.
