The sleeve gastrectomy is a restrictive procedure. It involves only the stomach, no intestine is involved. Sleeve gastrectomy has also been called partial gastrectomy and vertical sleeve gastrectomy. It consists of making the stomach, that looks like a pouch, into a long tube, or “sleeve”. Two thirds of the stomach is removed. This provides quicker satiety, or feeling of fullness, and a decreased appetite. The smaller stomach pouch restricts food intake by allowing only a small amount of food to be eaten at one time. After the separation of the stomach into a smaller tube, the remainder of the stomach is removed. The valve at the outlet of the stomach remains, this provides for the normal process of stomach emptying to continue which allows for the feeling of fullness.
This procedure is typically referred to as a “2 Stage Procedure” as it is designed for initial weight loss in the Superobese and will usually be followed with a second surgical procedure such as a Gastric Bypass or Duodenal Switch.
