What Is Laparoscopic Roux en Y Gastric Bypass?

This procedure is also done via the laparoscopic or keyhole technique. A small pouch of upper stomach is created and separated from the rest of the stomach using specially designed surgical staplers. This decreases the stomach capacity such that the patient eats a smaller amount.

Food is then directed further down the path of the small intestine. The length of intestines left to absorb calories is shorter causing a certain degree of malabsorption and reducing the amount of calories and nutrients absorbed.

Why Laparoscopic Roux en Y Gastric Bypass?

This is recommended for long-term weight loss and improvement of obesity-related medical problems such as diabetes, hypertension and high cholesterol (also known as the metabolic syndrome). If you have problems with the amount of food eaten, Laparoscopic Roux en Y Bypass may be a good option for you.
