Duodenal Switch Operation and Stomach Intestine Sparing Surgery (SIPS)

What Is It?

These procedures involves a sleeve gastrectomy being performed and the small intestine re-routed to produce malabsorption to effect weight loss. It produces a very good control of diabetes (>95%) and other obesity-related diseases.

The duodenal switch operation is very effective in creating weight loss.  This procedure has been performed for more than 10 years with good long term outcomes.

The SIPS procedure is like the mini- gastric bypass version of the duodenal switch. It is done with one anastomosis and relies on malabsorption as well.

This procedure is relatively new with not much long term data.

Advantage :

Excess weight loss of >80 to 90%

High diabetes remission rate

No or very low incidence of dumping syndrome

Minimal risk of ulceration at the new joint (anastomosis)

Disadvantage:

Increased malabsorption

Increased requirement of vitamin supplements

Needs close long term follow up

2 to 5% chance of needing revisional surgery for malabsorption

Internal hernia and bowel obstruction risk 2-4%

Fat malabsorption can result in frequent loose stools, abdominal cramping, and foul-smelling flatulence
