Single Anastomosis Duodeno-Ileal Bypass with Sleeve Gastrectomy (SADI-S)
Single Anastomosis Duodeno-Ileal Bypass (SADI-S), also known as Stomach Intestinal Pylorus-Sparing Surgery (SIPS) is a newer modified version of the duodenal switch bariatric surgery. SADI-S surgery combines the benefits of sleeve gastrectomy and intestinal bypass.
The benefit of SADI-S is that only one bypass is made instead of two, which has its benefits.
The sleeve gastrectomy removes 75% of the stomach, which is excellent for weight loss patients as they benefit from less hunger due to lower ghrelin (hunger hormone) levels, and ultimately eat less.
What is SADI-S Weight Loss Surgery?
The SADI-S weight loss surgery is a two-step procedure, beginning with a sleeve gastrectomy. The stomach is reduced to a small portion of its original size by surgically removing up to 75% of the stomach.
The next step is the intestinal bypass, which involves joining the small bowel (duodenum) to the distal section of the small intestine, the ileum. Using the duodenum as the connection point preserves the pylorus. Bypass length of the small bowel will be determined by the amount of weight loss that is required.
The result is that food will bypass the first part of the small intestine, which will ultimately cause a reduction in the amount of fats, calories and sugars absorbed.
You will also experience less hunger due to slower digestion of food, also triggering the release of intestinal hormones earlier to tell you to stop eating.
What are the advantages of SADI-S?
- Combines the benefits of the sleeve and bypass surgeries
- One anastomosis, instead of two bypasses
- Reduced risk of internal hernia
- Reduced risk of dumping and diarrhoea over other bypass surgeries
- Maintains good weight loss
- Acts as a good revision surgery
- Preserves the pylorus, which means less gut interference
What are the disadvantages of SADI-S?
- Increased risk of leakage, as there are two staple lines (bypass and sleeve)
- May produce a bowel obstruction in the long term
- Malabsorption of vitamins and minerals
- More frequent bowel movements
- May suffer from dumping syndrome
Is SADI-S weight loss surgery safe?
As with any invasive surgical procedures, there are the usual associated risks such as bleeding, infection and others.
However, with the SADI-S surgery, there are also risks associated with weight loss surgery such as infection, leaking and malabsorption (dietary supplements will be required).
Dr Stephen Watson and his team will cover all of the risks during an initial consultation.
How much weight can be lost from the SADI-S surgery?
The results of the SADI-S procedure differ per patient; however, you may be able to lose up to 80-90% excess weight if you follow the instructions of your surgeon and dietician.
Recovery after SADI-S surgery
After your surgery, you will have to spend time recovering and a few days in the hospital. You can expect some pain; however, we will administer pain medication to help you.
For the first weeks post-surgery, you will have to follow a liquid-only diet as well as take vitamin and mineral supplements, as outlined by your diet plan.
