The Vertical Sleeve Gastrectomy (VSG) has some advantages over the AGB, as there is no foreign body placed around the stomach and over the gastric bypass, as there is no bypass. It is not reversible, as 85 percent of the stomach is permanently removed from the body, but this surgery can be converted to other weight loss operations.
With less than 14 years of data, long-term results on weight and nutrition are not known. However, we estimate the VSG to be slightly less effective than the GBP but more effective than the AGB. It still may be the procedure of choice in certain circumstances.
For example, when a patient has had multiple previous intestinal operations, has the need for optimal absorption of medication, or has intrinsic bowel problems, this procedure may be the best option.
