Overview

SADI-S surgery in Arizona is a newer, improved duodenal switch surgery for bariatric weight loss patients.

Opting for the SADI-S procedure provides a safer route when compared to the traditional duodenal switch, as it diminishes the likelihood of leaks and malnutrition through its single intestinal connection. The SADI-S avoids bowel division, thereby reducing the risks.

Benefits of SADI-S Surgery:

Benefits of SADI-S surgery compared to other bariatric surgeries:

75–90% excess weight loss

Performed laparoscopically

SADI-S is both restrictive and malabsorptive

Decreased appetite and increased feeling of satisfaction

Reduced risk: One intestinal connection is made instead of two, meaning less surgical time and risk of intestinal leakage.

How SADI-S Works

SADI-S (loop DS) combines two bariatric surgeries: Singe Anastomosis Duodenoileostomy + Sleeve Gastrectomy = The Single Anastomosis Duodenal Switch-Sleeve (SADI-S).

Step 1

Sleeve Gastrectomy

The first step of the SADI-S procedure involves performing a sleeve gastrectomy. This entails removing a large portion of the stomach, typically around 80-85%. The remaining portion of the stomach is reshaped into a narrow tube or sleeve-like structure. This reduction in stomach size restricts the amount of food you can eat, leading to a feeling of fullness with smaller meals.

Step 2

Intestinal Rerouting

After the sleeve gastrectomy, the surgeon performs an intestinal rerouting. The surgeon divides the upper part of the intestines below the sleeve, then measures the amount of intestine to be bypassed and attaches it to the duodenum. This allows food to pass directly from the stomach into the lower part of the small intestine, bypassing a significant portion of the upper small intestine.

The switch reroutes food. This prevents the body from absorbing as much fat and calories. This combination of surgeries results in dramatic weight loss in a short amount of time.

Restrictive and Malabsorptive Effects

The SADI-S procedure combines both restrictive and malabsorptive mechanisms to promote weight loss. The reduced stomach size limits the amount of food that can be consumed, causing reduced calorie intake. Additionally, by bypassing a portion of the small intestine where nutrient absorption typically occurs, the SADI-S procedure reduces the number of calories and nutrients absorbed from the food you eat.

Am I A Good Candidate?

Candidates for switch procedures typically have a Body Mass Index (BMI) above 40, or have over 100 pounds of excess weight. Gastric bypass may be an option for people with a BMI between 35-40 who suffer from chronic conditions or life-threatening complications associated with obesity.

Switch procedures can also be done after a prior sleeve gastrectomy to further weight loss in those suffering from extreme obesity.

Pros

Cons

Excellent Outcomes

The duodenal switch is one of the most potent weight loss surgeries available, typically resulting in patients shedding 70-90% of their excess weight within the initial 2 years post-surgery.

Improve Weight-Related Conditions

Most patients experience significant improvement or resolution of weight-related conditions such as type 2 diabetes, hypertension, sleep apnea, and heart disease.

Long-Term Success

Higher success rates, with patients maintaining a significant amount of weight loss for many years post surgery.

Potential for Revision:

In cases of inadequate weight loss or complications, the SADI-S procedure can be revised or converted to other bariatric procedures like the Roux-en-Y gastric bypass or traditional duodenal switch.

Irreversible

A duodenal switch procedure is irreversible and permanent, similar to gastric sleeve.

Patients must commit to making lifelong improvements and change to ensure the long-term success.

Complex Procedure

The SADI is a technically complex and intricate procedure, which makes it important to choose an experienced surgeon who performs the procedure on a regular basis.

Vitamin Deficiency

As this is a malabsorption procedure, vitamin deficiencies may happen. An experienced registered dietitan will provide specific recommendations while closely monitoring for adequate protein intake, signs of malnutrition and other vitamin deficiencies.

Take 60-second assessment

After SADI.

When used appropriately, the SADI-S can significantly improve health and result in dramatic weight loss. Approximately 95% of patients experience an improvement in quality of life and resolve obesity-related health conditions.

Because of the significant malabsorption, nutrition status must be monitored closely. Labs will be ordered frequently, and you will be encouraged to follow up with your dietitian often. Vitamin supplementation is required to avoid nutritional deficiency. Fat and carbohydrate digestion will be significantly altered, so a low-fat and low-sugar diet should be followed after this surgery.

Recovery After the SADI-S

Recovery after SADI-S may be done outpatient, or require an overnight stay in the hospital. Patients usually return to work within 1-2 weeks after the procedure. Because the procedure significantly shortens the digestive tract and reduces the body’s ability to absorb calories, it is important that patients follow all post-operative recommendations for nutrition and vitamin supplementation to avoid possible life-threatening deficiencies.

FAQ

What is SADI Surgery?

The SADI is a two-step procedure that promotes weight loss by restriction and malabsorption.

How does SADI help with weight loss?

SADI promotes weight loss by restricting the amount of food that can be eaten and causing significant fat and carbohydrate malabsorption. The smaller stomach pouch created limits the amount of food that can be consumed at one time, while the rerouting of the intestines causes food to be digested faster before it's fully absorbed.

Is SADI reversible?

Yes and No. The sleeve that is created in step 1 of the SADI cannot be reversed. However, the length of intestines can be changed if needed for weight loss or medical purposes.

What is the recovery period for SADI?

The recovery period after the SADI-S is similar to other bariatric procedures. Most patients can return to normal activities within 1 - 2 weeks after the surgery. However, it's important to follow post-operative guidelines provided by your healthcare team for a smooth recovery.

Will I need to make changes to my eating habits after surgery?

Yes, nutrition changes are necessary after SADI. You will be advised to follow a specific post-operative diet plan that includes gradual progression from liquids to solid foods. You will also need to adopt long-term changes, such as smaller portion sizes and nutritious food choices, to support weight loss and overall health.

How long does it take to see weight loss?

Weight loss results vary among individuals, however the SADI typically results in rapid weight loss. Some patients may lose up to 80% of their excess weight within one year after surgery.

Are there any potential risks or complications associated with SADI?

All surgery has risks, however the SADI has a low reported complication rate. Regular follow-up visits with your bariatric team are important to monitor for and address any potential issues.

Will I be able to eat normally after SADI?

While you will be able to eat solid foods after recovery, but portion sizes will be significantly smaller. Because of the malabsorption component of the procedure, a low-fat and low-sugar diet should be followed. The goal is to promote healthy eating habits and portion control for long-term weight management.
