Roux-en-Y Surgery

Gastric bypass is both restrictive and malabsorptive surgery. In other words, it both reduces the size of your stomach and limits the amount of nutrients your intestines can absorb.

It is called “Roux-en-Y” because the two new connections form a Y.                                                            

The restrictive part of Roux-en-Y surgery involves making the stomach smaller. The surgeon will cut the stomach, leaving a pouch about the size of a small egg. This will make you feel full very quickly.

The malabsorptive part of the surgery involves rearranging the small intestine so that it absorbs fewer calories and nutrients. 

  1. The surgeon will cut the first section of
    the small intestine (the duodenum) loose from the second section (Roux).
  2. The surgeon will pull the Roux up and attach it to the new stomach pouch.
  3. Finally, the surgeon will attach the bottom of the duodenum to the small intestine.

From now on, nutrients will totally bypass both the larger stomach and duodenum. This means that the body absorbs fewer calories and nutrients than before.

Advantages

  • People who have gastric bypass have a higher initial weight loss than those who have purely restrictive procedures like LAP-BAND® Surgery.  However, studies show that over time weight loss for these procedures tends to even out. 
  • Gastric bypass does not involve placing a foreign object (like a gastric band) inside your body, so you do not have to worry about having a reaction to the object or being allergic to it.
  • You will not need additional adjustments to make your stomach smaller, as with LAP-BAND®, in order to lose more weight.
  • You can maintain good health as long as you:
    • Eat a healthy diet and take the right vitamin and mineral supplements
    • Work with our dietitian to develop a healthy eating plan
    • Continue your follow-up diet, exercise and behavioral program.

Risks

  • Anytime you have anesthesia or surgery, there is a risk of bleeding, blood clots, other complications or death.
  • Gastro-intestinal surgery can cause leaks, ulcers, perforations and internal hernia, bowel obstruction and fistulas.
  • Gastric surgery puts you at higher than normal risk of developing gallstones and gallbladder disease.
  • Do not smoke. Smoking would put you at high risk for infection, blood clots, slow healing and other life-threatening complications.
  • You will have to eat differently for the rest of your life.
    • Foods that you eat now may cause discomfort, nausea or vomiting after your surgery.
    • If you eat sugars and sweets, you can trigger dumping syndrome -- symptoms can include nausea, weakness, sweating, anxiety and heart palpitations after eating. This is not usually a serious health risk, but it can be painful.
    • Bypassing part of your intestine limits your body’s absorption of some important vitamins and minerals: iron, calcium, Vitamin B12 and folic acid. You will need to take daily supplements for the rest of your life.
      If you over eat, you can stretch your stomach opening (stoma) or pouch.
  • You will not lose weight or maintain your weight loss unless you eat a healthy diet and exercise regularly. This is the reason we stress long-term follow-up with our center and your doctor.
