Vertical sleeve gastrectomy (VSG) is a weight loss surgery that consists of removing a majority of the stomach and creating a new stomach about the size and shape of a banana. Bariatric surgeons at the Massachusetts General Hospital Weight Center typically perform vertical sleeve gastrectomy as a minimally invasive procedure for patients with obesity.VSG is recommended for patients based on the following benefits:
To qualify for this procedure, patients must have a Body Mass Index (BMI) of 40 or greater, or a BMI of 35 or greater plus a medical condition such as type 2 diabetes, high blood pressure or sleep apnea. Patients must also have tried other weight loss approaches that did not lead to significant and sustainable weight loss.
During VSG, the surgeon removes a majority of the stomach, creating a new banana-shaped stomach from the remaining component. This procedure decreases the production of ghrelin, the hunger hormone, so patients are less hungry. Additionally, the new stomach processes food faster, creating early feelings of fullness. At Mass General, VSG is usually performed laparoscopically with a few small incisions. Surgeons use narrow cylindrical tubes called trocars to access the abdominal cavity through small incisions in the upper abdominal wall. The duration of this procedure ranges from 30 to 60 minutes. After the procedure, you will stay at the hospital for one or two nights. We recommend taking off three to four weeks from work.
You may be required to enroll in the Mass General Weight Center’s pre-surgery nutrition program before you can undergo vertical sleeve gastrectomy. All patients scheduled for weight loss surgery are required to lose some weight prior to surgery. Weight loss before bariatric surgery results in a decrease of the size of the liver, commonly known as “shrink the liver” diet. This size decrease in the liver makes the surgery less difficult and faster, reducing postoperative complications. Your Mass General dietitian will create a meal plan specifically tailored to your weight loss goals. Learn more about preparation for bariatric and metabolic surgery
At the Mass General Weight Center, your care team develops an individualized postoperative program to monitor, guide and support you after the vertical sleeve gastrectomy.
