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 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 over 500 pounds.

Disadvantages of the Sleeve Gastrectomy Weight Loss Surgery

• Potential for inadequate weight loss or weight regain. While this is true for all procedures, it is theoretically more possible with procedures that do not have an intestinal bypass.

• Soft calories such as 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.
