The Vertical Sleeve Gastrectomy is a restrictive bariatric operation.  It generates weight loss by restricting the amount of food that can be eaten without any bypass of the intestines or malabsorption.  The stomach is divided vertically and more than 85 percent is removed.  The remaining stomach is shaped like a thin banana and measures from 2-5 ounces.

Previously performed for only those who are high risk or super-super-obese - today it is being performed on patients who are interested in avoiding a foreign body and/or do not want to maintain follow-up care through routine adjustments of a gastric band. 

Advantages

No dumping syndrome

• Minimizes chance of ulcer occurring
• Chance of nutritional deficiences are almost eliminated
• Eliminates the portion of the stomach that produces the hormones that stimulates hunger

Disadvantages

• Non-reversible
• Considered investigational by some surgeons and insurance companies
• Potential leaks and other complications related to stapling may occur

Ultimately, there are various appropriate treatment modalities for each patient, and surgeons must use their judgment in selecting from among the different feasible treatment options.
