Single Anastomosis Duodeno-ileostomy (SADI) is an advanced weight loss surgery designed to help individuals struggling with severe obesity and related metabolic conditions. SADI is a modern, minimally invasive procedure that combines stomach size reduction with intestinal rerouting to deliver significant, long-lasting weight loss results.
This procedure is a variation of the Duodenal Switch (BPD/DS) surgery but uses only a single intestinal connection instead of two, simplifying the operation while still providing the same metabolic benefits. At the heart of the SADI procedure is its ability to not only help patients lose weight but also significantly improve diabetes, hypertension, and other obesity-related conditions.
SADI is typically recommended for patients who are severely obese and have not had success with traditional weight loss methods. Ideal candidates generally have a BMI of 40 or higher, or a BMI of 35 or higher accompanied by obesity-related conditions, such as type 2 diabetes or hypertension. For individuals who have struggled to achieve or maintain weight loss through diet, exercise, or other surgical options, SADI offers a more permanent solution that targets both weight loss and metabolic improvement.
Candidates must be in good overall health, with a willingness to adhere to dietary guidelines and regular medical checkups. Not everyone is a fit for the surgery.
SADI combines two steps: sleeve gastrectomy, where most of the stomach is removed, and intestinal rerouting, connecting the duodenum to a loop of the ileum. This restricts food intake and reduces calorie absorption, leading to weight loss.
The single anastomosis minimizes risks and recovery time compared to traditional duodenal switch surgery while still improving metabolic health. This combination of stomach restriction and bypass helps improve diabetes, high blood pressure, and other related conditions.
The Single Anastomosis Duodeno-ileostomy (SADI) procedure offers numerous benefits for patients seeking a long-term solution to obesity. One of the most significant advantages is its ability to deliver sustained weight loss, with patients typically losing 70-80% of their excess weight within 18-24 months after surgery. This is due to the combined effect of stomach reduction and intestinal bypass, which limits calorie intake and absorption.
Another key benefit of SADI is its positive impact on metabolic health. Many patients experience significant improvements in type 2 diabetes, sleep apnea, and high blood pressure following surgery.
After SADI surgery, patients stay in the hospital for 1-3 days and follow a liquid diet for 1-2 weeks, gradually moving to solid foods. Most can return to light activities in 4-6 weeks, with full recovery taking a few months. Avoiding strenuous activities and following the surgeon’s diet guidelines is key during this time.
Post-surgery, patients need lifelong vitamin supplements and a high-protein, low-carb diet. Regular follow-up visits ensure progress monitoring and proper nutrition, with light exercise encouraged to maintain weight loss. Blood tests are essential to check vitamin and mineral levels.
