Single Anastomosis Duodeno Ileostomy + Sleeve (SADI-S)
Struggling to lose weight?
SADI-S might be the breakthrough you’ve been waiting for.
What is SADI-S?
SADI-S combines two proven bariatric procedures: the duodenal switch and the vertical sleeve gastrectomy. Here’s how it works and why it offers powerful benefits for long-term weight loss and improved health.
1. Duodenal Switch
This procedure removes a portion of the stomach and reroutes the small intestine to reduce calorie and nutrient absorption. Unlike standard gastric bypass, it bypasses a larger section of the intestine, resulting in greater malabsorption and enhanced weight loss.
2. Sleeve Gastrectomy
In this surgery, a large part of the stomach is removed, creating a smaller, sleeve-shaped stomach that limits how much you can eat and helps reduce calorie intake.
3. Combining Both for Greater Results
SADI-S merges these two procedures into one streamlined solution, delivering enhanced weight loss outcomes, the combined benefits of restriction and malabsorption, and a more effective, long-term solution for treating obesity.
Health Benefits Beyond Weight Loss
SADIS doesn’t just support weight loss — it also helps improve other health issues. Studies show it can lead to better outcomes for conditions like type 2 diabetes, high blood pressure, and sleep apnea.

Type 2 Diabetes: Improved blood sugar control.

High Blood Pressure: Many patients see reduced levels.

Sleep Apnea: Breathing during sleep often improves.
Considerations and Potential Risks
- While SADI-S is a promising weight loss solution, it’s important to note that it’s not without risks. As with any surgery, there are potential complications, such as bleeding, infection, and intestinal obstruction.
- Additionally, SADI-S can lead to malabsorption of nutrients, which can result in vitamin and mineral deficiencies. Patients who undergo SADI-S will need to take vitamin and mineral supplements for the rest of their lives to prevent deficiencies.
Is SADI-S right for you?
SADI-S is a promising weight loss procedure designed for people struggling with obesity and related health conditions.
Why It Works
This one-stage surgery combines the benefits of a sleeve gastrectomy and a duodenal switch to enhance weight loss results and overall health.
What to Consider
While there are potential risks and complications, many patients experience significant, lasting results—making SADI-S a powerful option when guided by medical advice.
Who is a Suitable Candidate?
The best candidates for Single Anastomosis Duodeno-ileostomy with Sleeve are those battling morbid obesity. It is ideal for those who want a better weight-loss method than a gastric bypass and sleeve.
Among its benefits are better long-term weight loss, diabetes treatment, lower chance of weight regain, less acid reflux, and reduced risk of stomach ulcer than those provided by bypass and sleeve.
SADI-S has proven to be an effective solution to obesity and its negative effects on patients’ health. It is also a good option for those who have undergone a restrictive bariatric procedure and have had trouble with keeping the weight off. Generally, good candidates of SADI-S include:
- BMI of 50 and Over
Obesity-related diseases including hypertension, high fasting plasma glucose, and a high body mass index are considered three out of the four biggest global health threats today (smoking is the fourth). In the United States, more than one-quarter of patients interested in bariatric surgery are super obese. The prevalence of comorbidities in those with a BMI greater than 50 includes a significant increase in cardiovascular mortality. SADI-S can help patients with super obesity reduce these associated risks. Previous Bariatric Surgery
With the right support and care, SADI-S can be a life-changing procedure that helps you achieve your weight loss goals and improve your overall health and wellbeing.Patients who have undergone options like gastric sleeve or gastric band surgery in the past who failed to shed excess weight can benefit from SADI-S revision surgery. Similarly, patients who lost weight initially but then regained substantial weight after gastric band or gastric sleeve surgery can benefit from SADI-S revision surgery. Unfortunately, since this method uses a similar malabsorption method, patients who have received a duodenal switch are not eligible for this procedure.
