Laparoscopic vertical sleeve gastrectomy (VSG) is a restrictive procedure that can be an alternative to gastric banding, with no foreign body implantation. It can be done as a standalone procedure, or as a stage procedure for high risk patients. Typically, the expected weight loss is approximately 45 â 70% of excess body weight, which is comparable to the gastric banding (Lap Band). Though the degree of weight loss is more rapid and consistent within the first year. Laparoscopic Sleeve Gastrectomy (VSG) versus Lap Band. The advantages of the VSG over the Lap Band are: It does not require the implantation of a foreign body such as a silastic ring used in gastric banding.
