Roux-en-y - RNY

This operation is the most common gastric bypass procedure. With this procedure a portion of the stomach is sectioned off, creating a small pouch for reduced food intake. The pouch will usually hold about one ounce of food or less, which causes the feeling of fullness after just a few bites. The size of the pouch varies with different doctors.

ADVANTAGES

• greatly controls food intake
• dumping syndrome -  dumping conditions to control intake of sweets
• reversible in an emergency - though this procedure should be thought of as a permanent

DISADVANTAGES

• staple line failure
• ulcers
• narrowing/blockage of the stoma
• vomiting if food is not properly chewed or if food is eaten to quickly
