Roux-N-Y-Gastric Bypass

What is a Roux-N-Y-Gastric Bypass?
Gastric bypass is a restrictive and malabsorptive procedure that is used to treat morbid obesity by making the stomach smaller and allowing food to bypass a part of the small intestine.



What is a Roux-en-Y Gastric Bypass?
Gastric bypass is a restrictive and malabsorptive procedure that is used to treat morbid obesity by making the stomach smaller and allowing food to bypass a part of the small intestine. Because of these changes, you will feel fuller more quickly and consume fewer calories. You will also absorb fewer calories, leading to overall weight loss.

How is a Laparoscopic Roux-en-Y Gastric Bypass performed?
Laparoscopic surgery uses a thin, telescope-like instrument called a laparoscope which is inserted through a small incision in the umbilicus. The laparoscope is connected to a tiny video camera which projects a video image of the operative site onto video monitors in the operating room. The abdomen is inflated with carbon dioxide, a gas, to allow your surgeon a better view of the operative area. A total of six incisions will be made with an umbilical incision, two incisions on each side of the upper abdomen and one just below the breast bone. Instruments are inserted through these incisions.

In a Roux-en-Y gastric bypass, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples or sutures. The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum). The old stomach remains intact and functional, secreting necessary enzymes for digestion into the small intestine.

Why Laparoscopic?

  • ___Six tiny scars instead of one large abdominal scar.
  • ___Shorter hospital stay in uncomplicated cases.
  • __ Reduced post-operative pain.
  • ___Shorter recovery time and quicker return to daily activities, including work.
  • What can I expect after surgery?
    It is important to follow your doctor’s instructions after surgery. An x-ray swallow study is done the day after surgery to evaluate the stomach pouch. If the stomach pouch looks good, you will be started on a liquid diet. It is very important that you follow a strict dietary protocol. If you are able to tolerate your liquid protocol, you should be discharged the second day after surgery. You will be on liquids for two weeks followed by a pureed diet eventually progressing to regular food after approximately a month’s time. It is important for patients to adhere to a vitamin regimen and close follow up with their surgeon.
