There are several names to describe this procedure — vertical gastrectomy, sleeve gastrectomy or vertical sleeve gastrectomy. This is a newer laparoscopic procedure being performed for weight loss.
The sleeve gastrectomy involves removing the portion of the stomach that functions mainly as a storage receptacle for food. You are left with a small tube shaped stomach and it doesn’t take much food to make you feel full. This is similar in concept to the adjustable gastric banding procedure as it is a restrictive procedure, limiting the amount of food that you can consume.
Most studies show that the amount of weight loss with the sleeve gastrectomy is slightly less than with a gastric bypass but slightly more than with adjustable gastric banding.
The average hospital stay is 1-2 days. The estimated weight loss is 60-70% of excess weight typically within the first year.
