Why Isn't the Duodenal Switch More Popular?

my bariatric surgeon doesn't perform the duodenal switch and said that only 2-3% of patients get it. but when i read online it said it had fewer complications than bypass. is this true and if so, why do so few patients opt for it?

Duodenal Switch - when to consider.

The duodenal switch otherwise known as the DS, is an excellent operation in the well selected patient that carries an overall low complication rate. The complication rate in terms of leaks is comparable to that of gastric bypass.  Certain patients with severe metabolic syndrome will benefit greatly from this opeation. DS is better at achieving overall weight loss for patients with BMI > than 50 and helping those patients get to a more "normal BMI". Also the DS is more resistant to weight regain which is far more common in gastric bypass patients. DS has potential issues or complicaitons such as protein and vitamin deficiencies. If you are a patient with high triglycerides and insulin dependent diabetes, and a high BMI, a DS procedure may be the right fit for you.

Duodenal Switch vs. Gastric Bypass

There are higher complications with the duodenal switch as opposed to a gastric bypass or a laparoscopic sleeve gastrectomy or a lap band.  There is a higher risk of leak and a higher mortality with the duodenal switch versus the gastric bypass. Also, there are many more nutritional and vitamin deficiencies with the duodenal switch. Duodenal switch patients have a higher incidence of diarrhea after the procedure, as well.
