Surgical Weight Loss Procedure Descriptions and Nutritional Guidelines

There are three procedures we offer patients through the Surgical Weight Loss Program at Sunrise Hospital. Each surgical weight loss procedure has a specially developed set of nutritional guidelines.

Sleeve Gastrectomy (VSG)

The sleeve gastrectomy is a restrictive procedure in which two-thirds of the stomach is removed, which provides for quicker satiety (sense of fullness) and decreased appetite. The remaining stomach looks like a long tube, hence the name sleeve, which restricts food intake by allowing only a small amount of food to be consumed at one time. Weight loss is achieved by both a reduction in stomach capacity and the production of the hormone ghrelin, which is associated with hunger and appetite. This procedure is also performed laparoscopically. This procedure works by restricting food intake without involving bypass of the intestinal track of a foreign object being placed around the stomach

Laparoscopic Adjustable Gastric Banding (LAGB)

The LAP-BAND® System is an adjustable silicone band that is inserted laparoscopically and placed (like a belt) around the upper part of the stomach. An access port allows the surgeon to adjust the inner surface by adding or removing saline. This creates a new, smaller upper stomach pouch and leaves the larger part of the stomach below. This new upper pouch can only hold a small amount of food, so patients will feel full sooner and are not hungry between meals.

Roux-en-Y Gastric Bypass (RYGBP)

A small stomach pouch is created which restricts food intake resulting in feelings of satiety following even small meals. Therefore, as gastric bypass implies, food is rerouted past most of the stomach and the first part of the small intestine. RYGBP achieves weight loss through both gastric restriction and malabsorption.
