Sleeve Revision to Single Anastomosis Duodenal Switch (SADI)

Maximize Your Weight Loss & Metabolic Health

If you previously had a gastric sleeve (sleeve gastrectomy) but have regained weight or have persistent diabetes or other metabolic conditions such as high cholesterol, a revision to single anastomosis duodenal switch (SADI) could be the answer.This transition is often considered for individuals who have a Body Mass Index (BMI) above 35 and facing obesity-related co-morbidities such as type 2 diabetes or hypertension that have not improved despite lifestyle changes.

Dr. Bonnor, a double board-certified surgeon, has the expertise and experience to see if you are a candidate for advanced revisional bariatric surgery, offering the duodenal switch as a powerful second step for lasting weight loss and metabolic health.

What Is a Sleeve to Duodenal Switch Revision?

This revisional bariatric surgery is designed for patients who:

✔ Regained weight or didn’t reach their goal after a sleeve gastrectomy
✔ Have metabolic conditions like diabetes
✔ Want a more powerful weight-loss tool than the gastric sleeve alone
✔ Are committed to long-term lifestyle changes for success

The duodenal switch (DS) is one of the most effective weight loss surgeries, combining:

  • Restriction – The stomach remains smaller, limiting food intake

  • Malabsorption – A significant portion of the small intestine is bypassed, reducing calorie absorption

  • Metabolic Impact – Alters gut hormones to enhance diabetes control, appetite suppression, and fat metabolism.

This makes DS is considered the powerful option for long-term weight loss and improving obesity-related health conditions.

Who Should Consider a Sleeve to DS Revision?

✔ You regained weight after a sleeve gastrectomy
✔ You need better diabetes or metabolic syndrome control
✔ You require additional malabsorption to maintain long-term results
✔ You have a BMI of 35+ with significant health conditions
✔ You are committed to post-op nutrition and lifestyle changes

If your gastric sleeve is no longer delivering the weight loss or health improvements you need, a DS revision can help you regain control.

Frequently Asked Questions About Revision Sleeve to Duodenal Switch

1. What is a revision sleeve to duodenal switch procedure?
A revision of a sleeve gastrectomy to a (SADI) is a surgical intervention designed to modify a previously performed sleeve gastrectomy to a more metabolically intense weight loss surgery. This procedure maintains the previous sleeve gastrectomy while creating an intestinal bypass, facilitating significant weight loss and improving metabolic health. This is an intestinal bypass not a gastric bypass which is an important difference as it relates to the construction and the subsequent potential complications that may occur on the SADI versus the gastric bypass.

2. Why would someone consider a revision from sleeve to duodenal switch?
Patients may opt for this revision if they have experienced insufficient weight loss, weight regain, or complications from the sleeve gastrectomy or intolerance to semaglutide (GLP-1). The SADI enhances the malabsorptive components of weight loss surgery.

3. Who is a suitable candidate for this revision?
Ideal candidates typically include individuals with a body mass index (BMI) over 35 who have not achieved desired weight loss goals after sleeve gastrectomy or those facing obesity-related health issues.

4. What are the potential risks associated with this revision surgery?
As with any surgical procedure, there are risks involved, including postoperative complications such as infection, bleeding, nutritional deficiencies, or bowel obstruction.

5. How does the nutritional approach differ after a duodenal switch compared to a sleeve gastrectomy?
After a duodenal switch, patients must adhere to a more rigorous nutritional plan due to the malabsorptive nature of the procedure. This includes monitoring protein intake, vitamin and mineral supplementation, and dietary adjustments to prevent deficiencies.

6. How does the duodenal switch compare to other weight loss surgeries?
The single anastomosis duodenal switch (SADI) is considered one of the most effective weigh loss surgery procedures for significant weight loss and resolving obesity-related co-morbidities, particularly in patients with higher BMIs. However, without proper nutritional and vitamin supplementation, it carries a higher risk for nutritional deficiencies as compared to a purely restrictive operation such as sleeve gastrectomy.
