The Vertical Sleeve Gastrectomy (VSG) or Laparoscopic Sleeve Gastrectomy (LSG) is an emerging weight loss procedure. It involves reducing the size of the stomach only, without any intestinal bypass or artificial device. Sleeve Gastrectomy OR Vertical Sleeve Gastrectomy OR Partial Gastrectomy This procedure involves surgery on the stomach only (it is only a restrictive procedure) and does not involve the intestine (which would make it malabsorptive). It basically consists of making a stomach that (before surgery) looks like a pouch into a long tube, or "sleeve". The sleeve gastrectomy procedure removes approximately 2/3 of the stomach, which provides for quicker satiety (sense of fullness) and decreased appetite. The smaller stomach sleeve restricts food intake by allowing only a small amount of food to be consumed in a single sitting. Surgical Procedure and Hospital Stay Over 98% of sleeve gastrectomies are performed laparoscopically, with an average of 5 small incisions.They all require full general anesthesia and about 1 to 1½ hours of surgical time. Most patients stay one or possibly two nights in the hospital. How Much weight loss is achieved? The vast majority of patients lose 50 to 80% of their excess weight in the first 12 months. . However,in the past, purely restrictive operations have led to LESS long term weight loss than the gastric bypass. The recent advances have advantage over the older procedures in that they eliminate most Ghrelin hormone production and help to reduce the sensation of hunger that people have. Advantages of the Vertical Gastrectomy Weight Loss Surgery The stomach is reduced in volume but tends to function normally so most food items can be consumed, albeit in small amounts. Eliminates the portion of the stomach that produces the hormone that stimulates hunger (Ghrelin). No dumping syndrome By avoiding the intestinal bypass, the chance of intestinal obstruction (blockage), anemia, osteoporosis, protein deficiency and vitamin deficiency are almost eliminated. Very effective as a first stage procedure for high BMI patients (BMI>55 kg/m2). Can be done laparoscopically in patients weighing over 500 pounds.
