Laparoscopic Roux en Y Gastric Bypass

 

 

How is it performed? 

Laparoscopically, the stomach is divided to create a small stomach pouch that restricts the amount of food or fluids consumed at any given time.  Next, the small intestine is attached to the stomach pouch to allow food to bypass the lower stomach, the duodenum (the first segment of the small intestine), and the first portion of the jejunum (the second segment of the small intestine) this bypass reduces the absorption of nutrients and thereby reduces the calorie intake.
