Also called vertical gastrectomy, vertical sleeve gastrectomy, or greater curvature gastrectomy, this procedure is restrictive and performed laparoscopically. The patient is required to stay in the hospital for two or three days.
The stomach is formed into one long tube by removing 85% of the stomach. The remaining stomach is banana shaped and can hold from 30-150 cc of food. The portion of the stomach removed is responsible for secreting Ghrelin which is the hormone that causes a feeling of hunger. This portion of the stomach also has the ability to stretch. The remaining portion does not have the same elasticity.
This procedure produces a loss of about 3-4 pounds per week.
