Duodenal Switch Operation/Stomach Intestine Sparing Surgery (SIPS) / SADI-S

Explained: Sips bariatric surgery Perth

What is SIPS surgery?

In the duodenal switch operation a sleeve gastrectomy is done and the small intestine re-routed to produce malabsorption to effect weight loss. It produces very good control of diabetes (>95%) and other obesity-related diseases as well as very good weight loss.

The SIPS bariatric surgery procedure is like the mini-gastric bypass version of the duodenal switch. It is done with one anastomosis. This procedure is relatively new with not much long term data however is suitable for a certain select group of patients.
