SADI-S surgery

Result

SADI-S surgery, or Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy, is a weight loss surgery designed for the treatment of obesity. It combines two surgical techniques: a sleeve gastrectomy and a duodeno-ileal bypass. This procedure is considered for individuals who have not achieved significant weight loss or have experienced complications from other forms of bariatric surgery, such as the Roux-en-Y gastric bypass or the gastric band. The SADI-S aims to reduce the stomach size and alter the digestive process, thereby facilitating significant weight loss and improving obesity-related conditions.

Procedure

The SADI-S surgery involves two main steps. First, a sleeve gastrectomy is performed, where approximately 80% of the stomach is removed, leaving a tube-shaped stomach about the size and shape of a banana. This part of the procedure reduces the amount of food the stomach can hold, leading to a feeling of fullness after eating only a small amount.

The second step involves bypassing a significant portion of the small intestine by connecting the end of the stomach (the duodenum) directly to a lower part of the small intestine (the ileum). This bypass reduces the amount of time the body has to absorb calories and nutrients from food, further aiding in weight loss.

Benefits

The SADI-S surgery offers several benefits, including significant and sustained weight loss, improvement or resolution of obesity-related comorbidities such as type 2 diabetes, hypertension, obstructive sleep apnea, and hyperlipidemia. The procedure is also noted for its simplicity and the reduced risk of nutritional deficiencies compared to other bariatric procedures, due to the preservation of the pyloric valve and a portion of the small intestine's absorptive capacity.

Risks and Complications

As with any surgical procedure, SADI-S surgery carries risks and potential complications. These may include leakage at the surgical site, infection, nutritional deficiencies, and the need for revision surgery. Long-term risks include the possibility of weight regain and complications related to malabsorption.

Candidates

Ideal candidates for SADI-S surgery are individuals with a Body Mass Index (BMI) of 40 or higher, or those with a BMI of 35 or higher who also have serious obesity-related health conditions. Candidates should have previously attempted to lose weight through diet and exercise. A thorough evaluation by a bariatric surgeon and a multidisciplinary team is necessary to determine if SADI-S surgery is the most appropriate option.

Recovery and Lifestyle Changes

Recovery from SADI-S surgery requires a commitment to lifestyle changes, including a diet high in protein and low in carbohydrates, regular exercise, and lifelong vitamin and mineral supplementation to prevent deficiencies. Patients will also need to undergo regular follow-up appointments to monitor their health and weight loss progress.

Conclusion

SADI-S surgery is a relatively new but promising option for individuals struggling with severe obesity and its related health conditions. While it offers significant benefits, it also requires a lifelong commitment to dietary and lifestyle changes. Patients considering this procedure should discuss the potential risks and benefits with a qualified bariatric surgeon.
