Loop Duodenal Switch (SIPS Procedure)

The loop duodenal switch, also called the SIPS Procedure, is a modification of the standard duodenal switch operation designed to provide equivalent weight loss with less risk.

SIPS stands for Stomach Intestinal Pylorus Sparing, which means that ingested food still passes through the pylorus after a SIPS procedure.  The pylorus is the valve at the bottom of the stomach that controls the rate of emptying of food into the small intestine.  Preserving the pylorus has numerous advantages over a traditional duodenal switch, such as bile reflux gastritis, ulcers, and hypoglycemia/dumping syndrome.  Also, using a loop of intestine to connect the stomach to rather than a traditional Roux limb, only one connection needs to be made which could potentially reduce the leak rate.

SIPS procedure is based on duodenal switch

Standard Duodenal Switch

Most long term studies on weight loss surgeries show that duodenal switch has the best long term weight loss and highest diabetes remission rates.  It has never gained wide acceptance though because of its higher short-and-long-term complication rates.  SIPS has the potential to provide equivalent long-term results with a much lower complication rate.  Our surgeons are the only in the region to offer this innovative procedure!
