Laparoscopic Gastric Bypass Long Island, NY

The American Society for Metabolic and Bariatric Surgery considers the gastric bypass surgery the “gold standard” for operations that focus on weight loss. Gastric bypass helps to reduce the number of calories that an individual can consume and process. This approach reroutes the digestive tract and creates a small pouch from the duodenum that then acts like the stomach.

The Laparoscopic Approach

Laparoscopic gastric bypass has quickly become the preferred way to complete this procedure. Laparoscopic surgeries typically make several small incisions rather than one large cut. The instruments and imaging equipment are then inserted through these small cuts to perform the operation. Reducing the overall size of the incision helps to reduce the potential for infection, and also allows patients to heal more quickly.

How the Surgery Works

During a laparoscopic gastric bypass, your surgeon will enter into the stomach area through the small incisions, and will then staple the top portion of the stomach. This reduces the amount of space that is available in the stomach. The portion of the stomach that is still available to hold food while it is processed is then referred to as a “pouch.”

A section of the intestine is then attached to this pouch, allowing food to bypass the lower stomach. Removing the lower stomach from the equation cuts down on the time your food spends in your body. This reduces the number of calories that your body can extract from the food.

​​​​​​​Once the operation has been completed, your physician will suture all of the incisions, and then you will be released after an observation period.

Benefits of Gastric Bypass

When patients strictly adhere to their physician’s instructions, weight loss is typically more rapid than any of the other bariatric surgical procedures. In fact, after a single year, patients report an average of 77 percent of excess body weight is lost.

After more than a decade, patients have between a 50 and 60 percent rate of keeping off excess body weight.

​​​​​​​In addition to the weight loss, patients also saw improvements with their ability to sleep, stopped snoring, reduced blood pressure, diabetes, and a decrease in the number of patients with depression.

Other Considerations

Gastric bypass surgery, laparoscopic, or the standard approach, both bypass the duodenum, which results in less ability of the body to take up calories and nutrients. While the reduction in the body’s ability to process calories can lead to positive changes, like weight loss, it can also mean that the body is less able to take up important nutrients, like vitamin B12.

For this reason, many patients who have had a gastric bypass surgery find that they will then need to take some supplements or injections to ensure that they are receiving proper nutrition.

While many patients have long-term success and their weight loss goals are realized, some patients will continue with poor nutritional habits and consistent overeating. Over time, this can cause a small pouch to become more stretched and allow for the storage and consumption of more food. Some patients will find that their weight is either maintained, or they can sometimes gain weight if poor eating habits continue.

​​​​​​​Finally, the stomach becomes more difficult to x-ray and interpret following the procedure. This means that the diagnosis of ulcers, bleeding, or malignancy occurs, that it can be difficult for doctors to identify and diagnose.
