|
| A good effective procedure as a sole choice of procedure in patients who are |
| • |
Volume eaters |
| • |
Stomach volume is reduced, but it tends to function normally so most food items can be consumed in small amounts. |
| • |
Eliminates the portion of the stomach that produces the hormones that stimulates hunger (Ghrelin). |
| • |
No dumping syndrome because the pylorus is preserved. |
| • |
Minimizes the chance of an ulcer occurring. |
| • |
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). |
| • |
Limited results appear promising as a single stage procedure for low BMI patients (BMI 35-45 kg/m2). |
| • |
Appealing option for people with existing anemia, Crohn's disease and numerous other conditions that make them too high risk for intestinal bypass procedures. |
| • |
Can be done laparoscopically in patients weighing more than 500 pounds | | |
| Absolute Contraindications |
| • |
Gastric outlet obstruction |
| • |
Large Hiatus Hernia |
| • |
Manometry showing a lax esophageal sphincter | | |
| Disadvantages of LSG |
| • |
Potential for inadequate weight loss or weight regain. While true for all procedures, it is theoretically more possible with procedures without intestinal bypass. |
| • |
Higher BMI patients may need to have a second stage procedure later to help lose all of their excess weight. Two stages may ultimately be safer and more effective than one operation for high BMI patients. This is an active point of discussion for bariatric surgeons. |
| • |
Soft calories from ice cream, milk shakes, etc., can be absorbed and may slow weight loss. |
| • |
This procedure does involve stomach stapling and therefore leaks and other complications related to stapling may occur. |
| • |
Because the stomach is removed, it is not reversible. It can be converted to almost any other weight loss procedure. |
| • |
Considered investigational by some surgeons and insurance companies. | | | |
