Stomach Intestinal Pylorus Sparing Surgery (SIPS)
What Is It?
The single-anastomosis duodenal switch, also called stomach intestinal pylorus sparing surgery (SIPS).
- Similar to the standard duodenal switch operation, except that the small intestine is only transected at the duodeum.
- The majority of the most stretchable portion of the stomach is permanently removed (as in a standard sleeve) but basic stomach function remains the same.
- Roughly half of the small intestine is bypassed, resulting in a moderate decrease in calorie absorption.
Weight loss is achieved both through restriction of food consumption and malabsorption, which results in very good long-term weight loss maintenance.
The SIPS procedure combines many of the benefits of both the gastric sleeve and the gastric bypass, including the following:
- Approximately 70% of excess weight loss
- Improvement/resolution in all major co-morbidities
- Little risk of “dumping” syndrome
- Provides predictable weight loss with great long-term success
- Minimal side effects typical of the duodenal switch
