Duodenal Switch

This procedure offers the ability to eat larger portions foods than sleeve gastrectomy, gastric bypass or adjustable gastric banding and has reliable and long lasting weight loss.  You may experience more bowel movements and need to closely monitor your vitamin, protein and mineral levels.

The stomach is reduced in size to a long, tube like vertical pouch, 4-5 ounces in size with moderate restriction of food intake.  The small intestine is divided to separate food from the digestive juices, causing significant malabsorption.  This surgery is best for patients with BMI of 50 kg/m2 and above if performed.

Dr. Feng no longer recommends this procedure due to long term concerns about side effects and complications.  Fewer than 2% of all patients in the world request or undergo this procedure.
