Learn about SASI surgery, its advantages, drawbacks, who qualifies, expected weight loss, and the full truth about vitamin supplementation after SASI. SASI surgery is one of the latest bariatric procedures, combining more than one technique to effectively treat morbid obesity and support significant weight loss.
What Is SASI Surgery?
SASI stands for Single Anastomosis Sleeve Ileal bypass — a bariatric procedure that combines sleeve gastrectomy with a partial intestinal bypass. During the procedure, the surgeon reduces the stomach (as in a sleeve gastrectomy), then connects part of the stomach directly to the small intestine, allowing food to travel via two pathways:
- The natural route through the stomach and intestines
- A shortcut directly to a portion of the small intestine
Who Are the Candidates for SASI Surgery?
- Patients with morbid obesity
- Those with a high BMI
- Those suffering from obesity-related conditions such as: Type 2 diabetes, hypertension, high cholesterol
- Individuals who have not achieved weight loss through diet or exercise
SASI Surgery Duration and Recovery Time:
The procedure typically takes 1 to 2 hours depending on the patient's condition. It is performed in two stages:
- Stage 1: Removal of up to 80% of the stomach
- Stage 2: Direct connection of the stomach to the small intestine
Recovery:
- Hospital discharge within 24–48 hours
- Return to light daily activities within approximately one week
- Full return to normal life within several weeks per doctor's instructions
Advantages of SASI Surgery:
- Effective weight loss with minimal impact on vitamin and mineral absorption
- Improvement of obesity-related conditions
- Combines the benefits of two procedures
- Reduces hunger due to reduced stomach size
Challenges of SASI Surgery:
- Requires post-operative dietary compliance
- Vitamin and nutrient monitoring is necessary
- Some patients may experience acid reflux
- Regular medical follow-up is required
The Vitamin Myth Surrounding SASI:
SASI is often marketed as the only bariatric procedure after which patients don't need vitamin supplements. In reality, vitamins are required after SASI just like after any other bariatric procedure, potentially for one to two years. Dr. Mohamed Tawfik makes sure to inform all patients of this reality so they are fully aware of every advantage and limitation before surgery.
Expected Weight Loss After SASI:
On average, patients may lose 60% to 80% of their excess weight within 12 to 18 months.
Signs of Successful SASI Surgery:
- Gradual and steady weight loss
- Improvement of obesity-related diseases
- Feeling full with smaller portions
- Improved daily energy and activity
- Weight stabilization upon reaching the goal
