Roux-en-Y Gastric Bypass

In the Roux-en-Y Gastric Bypass a small stomach pouch is created. The small intestine is then divided near its beginning. The distal segment is brought up and connected to the pouch. This is called the Roux limb. The other half contains the digestive juices, and is hooked back into the intestine downstream. It containes some of the malabsorptive properties of the Biliopancreatic Diversion, but not to the same extreme.

This operation has had very good long term results (~70% excess weight loss), and this has led to the gastric bypass being the most commonly done operation for weight loss in the United States. (In Europe, the lap-band is more common.)

Dr. Farkas is a laparoscopic surgeon, and does this operation through a minimally invasive technique. The same operation is done, but through small incisions, using a telescopic camera and long thin instruments. There are several advantages to having this done laparoscopically, including:

  • Less noticable scars
  • Less pain
  • Earlier return to normal activities
  • Less wound infections
  • Less incisional hernias
