Stomach Intestinal Pylorus- Sparing (SIPS) Surgery
By Daniel Cottam, M.D.
About SIPS
The SIPS procedure is simple a modification of the duodenal switch surgery that has been around for over 20 years. In the SIPS procedure, the intestine is not divided (no distal anastomosis and avoids a roux limb) and less of the intestine is bypassed than in a traditional DS so there is less protein and vitamin malnutrition. According to Dr. Daniel Cottam, the modifications make it easier to perform than the traditional duodenal switch and also reduces nutritional deficiencies and diarrhea while still helping patients achieve impressive levels of weight loss.
The potential advantages
-
By preserving three meters of intestine there are less nutritional needs for almost all patients compared to the traditional DS.
-
By preserving the pyloric valve, it does not cause an abrupt rise and fall of blood glucose. No Dumping like in gastric bypass surgery.
-
By not dividing the intestine with a distal anastomosis or a roux limb, it could potentially reduce risk of gastrointestinal symptoms and intestinal obstruction, and reduce the chance for surgical complications. This means that there is almost no chance for internal hernia formation.
-
By placing attachment after pyloric valve, it does not increase risk of bile reflux gastritits.
