SIPS (stomach intestinal pylorus preserving surgery) is a modified version of the duodenal switch, which has been used for the treatment of morbid obesity for 30 years. SIPS combines the benefits of sleeve gastrectomy and intestinal bypass.
Sleeve gastrectomy removes 75% of the stomach resulting in a reduced capacity to eat and a reduced level of ghrelin, the hormone which causes hunger. Intestinal bypass involves dividing the top part of the small bowel (duodenum) just beyond the outlet of the stomach (pylorus), and joining the lower part of the small bowel (ileum) to this top part.
This results in food bypassing part of the small intestine which causes a reduction in the absorption of fats, sugar and calories that are consumed. The amount of the small bowel bypassed can be varied depending on the desired weight loss.
Advantages of the SIPS procedure
Studies show SIPS can provide greater weight loss than either a standard sleeve gastrectomy or gastric bypass. Some other advantages of SIPS includes:
- Combines benefits of sleeve and bypass
- Less risk of dumping and diarrhoea than other bypasses
- Less risk of internal hernia
Disadvantages of the SIPS procedure
- Increased risk of leak as there are two staple lines, one for the sleeve and one for the bypass
- Longer operation and anaesthetic time.
How does Dr Kevin Dolan perform the SIPS procedure?
The SIPS procedure is a three-step process:
- Create sleeve gastrectomy.
- Transect top of small bowel just beyond outlet value of stomach.
- Connect a loop of the lower part of small bowel to the top end of small bowel.
Following your surgery, you will spend two or three days in hospital, and will be administered pain controlling medications to keep you comfortable. For the first two weeks following your surgery, you will be kept on a liquid diet. Your surgeon and dietician will give you a specific diet plan and instructions to follow after this. It is important to drink plenty of fluids throughout the day to avoid dehydration.
What are the Costs and Funding Options for SIPS Surgery?
There are a number of factors which may influence the final cost of surgery. Dr Dolan will be able to provide a more detailed quote after consultation.
Medicare rebates are available for this procedure and our surgery offers payment plans for patients.
Stomach Intestinal Pylorus Preserving Surgery FAQs
Stomach intestinal pylorus preserving surgery, or SIPS as it is commonly known, is a modified version of the duodenal switch procedure. SIPS combines the benefits of both intestinal bypass and sleeve gastrectomy to effectively treat morbid obesity. During the procedure, a large portion of the stomach is removed in order to reduce one’s capacity to eat and to reduce one’s level of ghrelin (the hunger hormone), while the top part of the small bowel is divided so that food bypasses part of the small intestine. This works by reducing the amount of fats, sugar and calories that are absorbed by the body.
According to studies, the SIPS procedure is able to provide greater weight loss than either a standard sleeve gastrectomy or gastric bypass procedure. Because the surgery combines the benefits of sleeve and bypass operations, it is often a very effective treatment for those who are morbidly obese. The surgery also has less risk of dumping and diarrhoea than other forms of bypass, and there also tends to less risk of internal hernia when compared to other surgical weight loss options.
The SIPS procedure tends to be a much longer operation than the other surgical weight loss options that are currently available. As a result, the anaesthetic time is longer than the other procedures. There is also an increased risk of leakage with SIPS. This is because there are two staple lines — one for the sleeve and one for the bypass. Dr Dolan will advise you as to whether SIPS is the best option for you, depending on your particular circumstances and health condition. He will also let you know about any other options available to you.
