Keyhole Gastric Bypass for Weight Loss

California rates for HCPCS 43644

A weight-loss operation done through small abdominal incisions with a camera, in which the stomach is divided to leave a small pouch and that pouch is joined directly to a loop of small intestine. Food then bypasses most of the stomach and the first stretch of the small bowel, so people feel full on much less and absorb fewer calories. A second connection is made further down so digestive juices rejoin the food stream.
