About This Surgery

First described in Spain in 2007 this has been made popular by surgeons Dan Cottam and Mitch Roslin from the USA who modelled their procedure on the original.

It’s considered similar to the most powerful weight loss operation the Duodenal Switch but with lower rates of diarrhoea and protein malabsorption. It is suggested for high BMI patients and or when Type 2 Diabetes Mellitus/Metabolic Syndrome control is indicated or weight regain after primary surgery.

Advantages

  • Effective Weight Loss: Significant weight loss with patients often experiencing around 80% excess weight loss.
  • Improvement of Metabolic Conditions: Improvement/resolution of obesity-related problems eg. type 2 diabetes, high blood pressure and high cholesterol.
  • Simplicity: SADI-S/SIPS combines sleeve gastrectomy with a single anastomosis duodenal-ileal bypass, making it technically simpler than an RNYGB.
  • Reduced Risk of Dumping Syndrome: Unlike RNYGB, SADI-S has a lower risk of dumping syndrome.
  • SADI-S/SIPS offers the best rates of Type 2 Diabetes Mellitus control of all weight loss operations

Disadvantages

  • Risk of Nutritional Deficiencies: Malabsorption of vitamins and minerals eg. iron, calcium, vitamin B12, and fat-soluble vitamins (A, D, E, K).
  • Long-Term Risks: Malnutrition, osteoporosis, and gastrointestinal issues may arise.
  • Limited Long-Term Data: SADI-S/SIPS is a newer procedure compared to RNYGB so limited long-term data on its safety and effectiveness exists.
  • Potential for Complications: Risks exist but are less common than RNYGB
  • Requires Skilled Surgeon: SADI-S/SIPS needs expertise in both sleeve gastrectomy and intestinal bypass techniques.

Is this right for me?

  • BMI: SIPS is offered as a primary operation to high BMI patients and as a revisional option after weight regain.
  • Health conditions: Obesity-related conditions like DM Type 2, high blood pressure, sleep apnoea can improve.
  • Previous weight loss attempts: Tried and failed to lose weight through diet, exercise, medications and previous surgery.
  • Commitment to Lifestyle changes: SADI-S/SIPS is a tool, it requires a commitment to long-term lifestyle changes including dietary changes and regular physical activity.
  • Medical/Surgical History: You will be evaluated to determine if you're a suitable candidate.
  • Risks and Benefits: Risks and benefits and alternative treatment options will be discussed.

It’s crucial to have an open and honest discussion with your New Me Surgeon to determine if SADI-S/SIPS is the right choice for you based on your circumstances, preferences and goals.

Surgery FAQs

What is SADI-S/SIPS?

SADI-S/SIPS is a weight loss surgery that combines sleeve gastrectomy with a single anastomosis duodenal-ileal bypass, reducing stomach size and rerouting part of the small intestine to limit food absorption.

How does SADI-S/SIPS differ from other bariatric surgeries like gastric bypass or sleeve gastrectomy?

SADI-S differs from other bariatric surgeries like gastric bypass by disconnecting the duodenum and joining it to the small bowel. The join is below the pylorus muscle which helps reduce dumping.

What are the potential benefits of undergoing SADI-S/SIPS surgery for weight loss?

Potential benefits of undergoing SADI-S/SIPS surgery for weight loss include significant and sustained weight loss, improvement or resolution of obesity-related health conditions such as type 2 diabetes and hypertension, and reduced risk of dumping syndrome compared to gastric bypass.

What are the risks and complications associated with SADI-S/SIPS surgery?

Risks and complications associated with SADI-S/SIPS surgery include nutritional deficiencies, malabsorption issues, risk of leaks, ulcers, bleeds or strictures at the bowel join site, and potential long-term complications such as osteoporosis and vitamin deficiencies.

What dietary and lifestyle changes are necessary after undergoing SADI-S/SIPS surgery?

Dietary and lifestyle changes after SADI-S/SIPS surgery typically involve consuming small, nutrient-dense meals, avoiding high-calorie and high-sugar foods, and incorporating regular physical activity to support weight loss and maintain nutritional balance.

How long is the recovery period following SADI-S/SIPS surgery?

The recovery period following SADI-S/SIPS surgery usually ranges from several weeks to months, with patients gradually resuming normal activities under New Me Surgery guidance.

Are there any long-term effects or considerations to be aware of after SADI-S/SIPS surgery?

Long-term effects or considerations after SADI-S/SIPS surgery may include the risk of nutritional deficiencies, osteoporosis, and gastrointestinal issues due to the malabsorptive nature of the procedure.

Who is an ideal candidate for SADI-S/SIPS surgery?

Ideal candidates for SADI-S/SIPS surgery are individuals with severe obesity (BMI ≥ 40)  with obesity-related health conditions, who have not achieved weight loss with other methods and are committed to making lifelong dietary and lifestyle changes.

How does SADI-S/SIPS surgery affect co-morbid conditions like type 2 diabetes or high blood pressure?

SADI-S/SIPS surgery can lead to significant improvement or resolution of co-morbid conditions like type 2 diabetes and high blood pressure, often even before significant weight loss occurs, due to changes in gut hormone levels and metabolic function.

What is the success rate of SADI-S/SIPS surgery in terms of sustained weight loss and improvement in health outcomes?

The success rate of SADI-S surgery in terms of sustained weight loss and improvement in health outcomes varies, but many patients experience significant and long-lasting weight loss, improvement or resolution of co-morbidities, and enhanced quality of life with proper adherence to post-operative guidelines.
