  • Procedure Overview

    • There are two steps during gastric bypass surgery:
    • The first step makes your stomach smaller
    • Roux-en-Y gastric bypass (RYGB) is a type of weight-loss surgery that reduces the size of your stomach to a small pouch – about the size of an egg. It does this by stapling off a section of it. This reduces the amount of food you can take in at meals.
    • With such a small stomach, people feel full quickly and eat less. This strategy is also called "restrictive," since the new stomach size restricts how much food it can hold.
    The second step is the bypass
    • The surgeon then attaches this pouch directly to the small intestine, bypassing most of the rest of the stomach and the upper part of the small intestine. This surgical technique is called a "Roux-en-Y.
    • The food you eat will now travel from the pouch into this new opening into your small intestine. Because of this, your body will absorb fewer calories. This weight loss method is called "mal absorptive."
    • Stomach stapling and Roux-en-Y are typically done during the same surgery and together are called a "Roux-en-Y gastric bypass."
    • Usually, surgeons do both laparoscopically (using tools inserted through small cuts in the belly). Whenlaparoscopy isn’t possible, surgeons may do a laparotomy (involving a large cut in the middle of the belly).
    • Advantages of laparoscopy over open surgery include:
    • Shorter hospital stay and quicker recovery
    • Less pain
    • Smaller scars and a lower risk of getting a hernia or infection
