Banded Sleeve Gastrectomy is a surgical procedure that can be performed by miniinvasive (Video)surgery. The procedure reduces the size of the stomach to about 10% of its original volume and results in a limited capacity of food intake. Patients feel full after eating a very small amount of food. The volume of the stomach after LCSG is between 80 and 120 ml. In sleeve gastrectomy, the left side of the stomach is surgically removed by cutting and stapling. This results in a new stomach which is roughly the size and shape of a 20 cm tube. A silastic ring is implanted in upper part of the sleeve. This operation does not involve any “rerouting” or reconnecting of the intestines, it is a simpler operation than the gastric bypass. Also very important is the fact that the operation preserves the pylorus, the muscle that regulates emptying of the stomach. This acts as “natures own functional gastric band” and allows food to remain in the stomach for a while, making the person feel full while the food trickles out. Coupled with the fact that there is no rearrangement of the bowel, it also means dumping and marginal ulcers are not a problem. The normal satiety mechanism is almost always regained by the operation.
