Patients who don’t want to have a long-term implanted medical device now have another option with the sleeve gastrectomy.
Through five small incisions, each between one and two inches long, the surgeon removes approximately 70 percent of the stomach. This new stomach has a total capacity of just three to five ounces, which means patients feel full or satisfied after eating only two to four ounces of food.
The laparoscopic sleeve gastrectomy has several advantages over the bypass:
- Because the normal flow of food through the GI tract is not altered, your risk of nutritional deficiencies is greatly reduced.
- When the outer portion of the stomach is removed, so is the hunger hormone, Ghrelin. This significantly reduces your desire to eat.
- According to published medical data, weight loss with the laparoscopic sleeve gastrectomy can be 60 to 70 percent of excess weight at two years.
- Research shows 60 to 70 percent of laparoscopic sleeve gastrectomy patients maintain their weight loss six years following surgery.
- No long-term risk of gastric ulcers and internal hernias with the sleeve, yet those risks remain with gastric bypass.
Sleeve Gastrectomy Advantages
- Reduces stomach capacity but tends to allow the stomach 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 (Grehlin).
- “Dumping syndrome” is avoided or minimized because the pylorus is preserved.
- Minimizes chance of an ulcer occurring.
- By avoiding the intestinal bypass, almost eliminates the chance of intestinal obstruction (blockage), marginal ulcers, anemia, osteoporosis, protein deficiency and vitamin deficiency.
- Appealing option for people who are concerned about the complications of intestinal bypass procedures or who have existing anemia, Crohn’s disease and numerous other conditions that make them too high risk for intestinal bypass procedures.
- Appealing option for people who are concerned about the foreign body aspect of the Banding procedures.
- Can be done laparoscopically thereby providing all the advantages of minimally invasive surgery: fewer wound and lung problems, less pain, and faster recovery.
