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. It is a restrictive form of bariatric surgery that helps with weight loss by limiting foot intake and controlling hunger sensations. After surgery the amount of food that can be eaten at any one time is greatly reduced. The surgery also helps to control hunger, because the upper portion of the stomach that produces the hunger stimulating hormone ghrelin is removed during surgery.
During this procedure, a bariatric surgeon removes about 85 percent of the stomach so that it takes the shape of a tube or sleeve. It does not involve cutting or rerouting the small intestine and it does not require an implanted weight loss device.This operation is performed laparoscopically, meaning that the surgeon makes small incisions as opposed to one large incision, or open. 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 after a person has lost a significant amount of weight. Some individuals are either extremely obese or have health problems which disqualifies them from having gastric bypass surgery or gastric banding. In these cases, the gastric sleeve may be recommended, either as an alternative method or as the first step in a two step bariatric process. It can be 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.
The gastric sleeve procedure will restrict the amount of food that can be eaten at any one time, but it does not restrict any certain foods from the diet as the digestive system still functions normally. It is up to the patient to adopt the healthy diet and active lifestyle that will promote weight loss. The average amount of weight loss is typically 30 to 50 percent of excess weight in the first eighteen months after surgery.
