Stomach Intestinal Pylorus Preserving Surgery

SIPS, also known as SADI, stands for Stomach Intestinal Pylorus Preserving Surgery.  This is a new bariatric procedure which is a variation of Biliopancreatic Diversion with Duodenal Switch (DS for short).  It is also known as sleeve gastrectomy (sleeve gastric or gastric sleeve) with loop duodeno-ileal anastomosis, or loop DS.

SIPS was designed by surgeons Daniel Cottam (Utah, USA) and Mitch Roslin (New York) modelled closely on the SADI-S procedure published by Dr Torres (Spain). 

SIPS is essentially a “super-charged” Sleeve Gastrectomy.  The first part of the operation is to create a Sleeve Gastrectomy as per usual procedure.  The second part is to bypass some of the small bowel from just beyond the stomach to reduce the body’s uptake of calories from food consumed.

The SIPS Procedure as an alternative to Gastric Bypass



SIPS is thought to be…

  1. A more powerful (but more complex) form of sleeve gastrectomy surgery
  2. An alternative to gastric bypass which gives similar results with less long term adverse effects than bypass
  3. A relatively simple and effective revision procedure for sleeve gastrectomy patients who have regained weight or not done well with their initial weight loss.

Early results from the USA and overseas have shown excellent weight loss with much less nutritional problems and diarrhea compared to other malabsorption-type procedures such as conventional Biliopancreatic Diversion with Duodenal Switch.

SIPS has potential advantages over the gastric bypass procedure including the following:

  1. Reduced ulcer formation
  2. Reduced internal hernia (twisted bowel) rates
  3. Reduced dumping syndrome and problems related to low blood sugar related
  4. Less food intolerances

Mr Clough will be offering SIPS surgery through the Epworth Hospital in Melbourne.

If you have regained weight or are unhappy with your outcomes after sleeve gastrectomy surgery it may be worth having a consultation with Mr Clough about the role of SIPS in this setting.
