Types of bariatric surgery

Prevea bariatric surgeons perform two kinds of bariatric surgery procedures—the Roux-en-Y gastric bypass and vertical sleeve gastrectomy. Both weight loss surgery procedures have their own benefits and risks. Below is a summary of the two procedures.

 

Roux-en-Y gastric bypass surgery


Commonly referred to as gastric bypass, this weight loss surgery reduces the stomach to a small pouch about the size of your thumb or a small egg. The pouch is reattached to the lower portion of your small intestine, bypassing approximately one-third of the small intestine. This reduces the amount of fat and calories you absorb from foods you are able to eat for even greater weight loss. This procedure works in two ways, restriction and malabsorption. The restriction comes from the tiny stomach pouch, which is only about 5 percent of your stomach. Malabsorption means less absorption of nutrients, which is a result of the intestinal bypass.

The surgery can be performed by either a laparoscopic, robotic or open approach. The average weight loss of patients who undergo this type of surgery is about 70 to 80 percent of excess body weight.

Vertical sleeve gastrectomy


The gastric sleeve or vertical sleeve gastrectomy (VSG) is also referred to as sleeve gastrectomy, vertical sleeve, or simply sleeve. This weight loss surgery removes about 85 percent of your stomach, leaving a thin tube or sleeve. Think of a banana, but only as wide as your index finger. There is no intestinal bypass, so this method is purely restrictive, meaning it restricts the amount of food that can be eaten at once.

The surgery can be performed by either a laparoscopic, robotic or open approach and average weight loss is 65 to 75 percent of excess body weight.

Prevea does not perform the lap band surgery. While the lap band surgery popular many years ago it doesn’t result in the weight loss or improvement in medical problems that the other forms of bariatric surgery have proven to show. In addition, the band can slip and/or erode, requiring another surgery to fix.
 
Bariatric surgery is a serious decision with life changing-results. Undergoing surgical treatment for weight loss requires a great deal of commitment from you, your family, friends and health care team.
