Gastric sleeve surgery, or gastric sleeve resection, is one of the newer types of bariatric surgery. This surgery can also be referred to as sleeve gastrectomy, vertical sleeve gastrectomy, tube gastrectomy and laparoscopic sleeve gastrectomy.
During this procedure a bariatric surgeon removes about 85 percent of the stomach so that it takes the shape of a tube or sleeve. This operation is performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large incision. He or she inserts a viewing tube with a small camera (laparoscope) and other tiny instruments into these small incisions to remove part of the stomach. The tube-shaped stomach that is left is sealed closed with staples.
In some cases, gastric sleeve surgery may be followed by a gastric bypass surgery or duodenal switch surgery after a person has lost a significant amount of weight. Called a "staged" approach to weight loss surgery, this makes the second procedure less risky than it would have been had it been the first and only procedure. The timing of the second surgery varies according to the degree of weight loss. It usually occurs within six to 18 months after the initial surgery.
