INTRODUCTION TO SLEEVE GASTRECTOMY
This operation is a "Restrictive" surgical weight loss procedure that limits the amount of food you can eat and helps you feel full sooner thereby reducing your overall caloric intake. Food consumed passes through the digestive tract in the usual manner and allows for normal digestion.
In this procedure, a narrow vertical "sleeve" of stomach is created resembling a long tube-shaped pouch. Approximately 75-80% of the stomach called the "Greater Curvature" is removed. It has been thought that this portion of stomach removed has the greatest concentration of cells producing the hormone "Ghrelin". This is the main hormone responsible for stimulating hunger and appetite!! Essentially, this procedure reduces the overall volume capacity of the stomach and also reduces the stimulus trigger for hunger, therefore causing a loss of appetite. These two combined effects result in significant weight loss similar to gastric bypass but without all of the side effects of the gastric bypass.
Benefits include natural food digestion and absorption without the side effects of malabsorption or "dumping syndrome", leading to possible nutritional deficiencies such as iron-deficienty anemia or calcium depletion leading to osteoporosis/osteopenia. The stomach is reduced in volume but tends to function normally. In addition, there is no intestinal re-routing as in the gastric bypass which may increase the risk of future intestinal obstruction/blockage, or complicate future intestinal surgeries. Overall, the sleeve gastrectomy is considered a safer operation compared to the gastric bypass.
Advantages of this procedure compared to Lap Band is the fact that there are no "Foreign Device" implanted, so there are no concerns for band slippage or erosions, no frequent adjustments, or potential implant/device infections.
