NJ Gastric Bypass (Roux-en-Y Gastric Bypass)

New Jersey Gastric Bypass

One of the most well-known surgical weight loss procedures is gastric bypass, also referred to as Roux-en-Y. Designed to reduce the amount of food you consume by removing a part of the stomach, gastric bypass is a procedure that helps patients achieve and maintain weight loss goals.

When gastric bypass is performed using the “open” approach, an incision is made in the abdomen extending from just below the sternum to an area slightly below the belly button. A stapling device is then used to create a tiny stomach pouch by partitioning the existing stomach, essentially changing its size and preventing too much food to be consumed. The “laparoscopic,” or minimally-invasive, approach follows the same guidelines as the “open surgery,” but is performed internally. Using five small keyhole-sized incisions, the surgeon relies on a camera that is inserted into one of the incisions to see inside the body, while using several small instruments inserted through the other incisions to perform the procedure. Part of our team approach includes strategic placement of some of these ports to be used later and to minimize your abdominal scarring.

Benefits of Gastric Bypass

Gastric bypass surgery offers many potential benefits. Typically, patients experience a shorter recovery and less scarring with laparoscopic surgery than with traditional open surgery. However, it is important to remember that laparoscopic surgery is not appropriate for every patient, and, in some cases, surgeons will not know if they can perform the procedure laparoscopically until the surgery is underway. Various medical conditions may make laparoscopic surgery unsafe for certain patients.

Risks and Considerations

Gastric bypass patients may experience dumping syndrome, a very uncomfortable result of consuming high fat and high sugar foods.

In some patients, if the pouch opening begins to enlarge after surgery an outpatient procedure may be necessary to reduce the opening

Staple line failure


Narrowing/blockage of the stomach

Vomiting if food is not properly chewed or if food is eaten to quickly

Weight re-gain is known to happen if dietary changes are not followed long term

Gastric bypass is major surgery and carries all the risks of a surgical procedure. Please contact us for more information on these risks.
