Vertical Sleeve Gastrectomy
Vertical Gastrectomy, or VG, involves the creation of a long, narrow vertical pouch measuring 2-4 oz. and is identical to the duodenal switch pouch but smaller and with no intestinal bypass.
VG significantly restricts the volume of food that may be consumed, with no malabsorption and no dumping. Patients are usually hospitalized for 1-2 days and return to work after 1-2 weeks.
Lifetime nutritional supplements required after this procedure include a multivitamin and calcium. Following surgery, patients must consume a very low calorie diet for the first 12-24 months. While the procedure results in no dumping or diarrhea, weight regain may be more likely than in other procedures if strict dietary modifications are not followed throughout the patient’s lifetime.
This weight loss surgery is used for high-risk or very heavy (BMI >60 kg/m2) patients as a “first stage” procedure. It is associated with a very low rate of complications because patients spend less time in the operating room and intestinal bypass is not performed.
