Procedures Performed by the Brooklyn Bariatric Group

The Roux-en-Y gastric bypass surgery (RYGB), commonly called gastric bypass, is a popular weight loss surgery that has been referred to as the gold standard of bariatric surgery.

RYGB works by restricting food intake and by decreasing the absorption of food. In laparoscopic gastric bypass surgery, the surgeon cuts across the top of your stomach, sealing it off from the rest of your stomach. This new stomach pouch is then attached to a piece of cut small intestine that is connected directly to the pouch. When you eat after a gastric bypass, food enters into this small pouch of the stomach and then passes directly into your small intestine. Food bypasses most of your stomach and the first section of your small intestine, and instead enters directly into the middle part of your small intestine. This results in fewer amounts of food intake and less absorption of calories leading to weight loss.  The gastric bypass essentially creates two channels in the intestinal tract - one for the food and a second for the digestive juices.

In Laparoscopic Sleeve Gastrectomy a small gastric reservoir is created that reduces the stomach size to 60-150 ml. 

The operation involves the removal of the upper rounded part of your stomach called the fundus.  The fundus is one of the parts of the stomach that produces ghrelin, the hormone that controls your appetite. While not yet completely understood, the removal of the fundus during sleeve gastrectomy seems to be one of the reasons why a sleeve gastrectomy is not just a restrictive procedure. Sleeve Gastrectomy preserves many of your natural anatomic structures and connections including the antrum and pylorus along with vagus nerve innervation. Approximately 75%–80% of the greater curvature is excised, leaving a narrow stomach tube.

This minimally-invasive procedure commonly called LAP-BAND® that involves placing an adjustable silicone band around the upper portion of the stomach, making a narrow opening through which food travels. The band works by restricting the amount of food a person can eat. The band can be tightened or loosened as needed.
