Sleeve gastrectomy and the band procedure, just like LAP-BAND or the REALIZE band, these are considered restrictive operations, meaning that basically, the procedure creates a smaller stomach and just reduces the amount of calorie the patient can get. Malabsorptive operation, like the biliopancreatic diversion that some people may be familiar with, or gastric bypass, involves bypassing a segment of small intestine. Therefore, less of what the patient eats gets absorbed. Therefore, you have a possibility of vitamin deficiency; iron deficiency is common in people who take gastric bypass procedure, and in these operations, it’s important for the patient to be on multivitamins, not as much under restrictive operations, not as much under band operation, not as important for the sleeve gastrectomy. And it’s important in the sleeve gastrectomy to mention that not only the patient has less space to eat, also because the stomach is removed, we know that the ghrelin hormone, which is also known as the hunger hormone, is remarkably reduced. So, there’s the second effect from this operation that my patients are just not hungry, and that’s why I think we have superior results compared to other banding procedures. I would like to emphasize that also I have a lot of experience with this. Not every program offers the sleeve gastrectomy. Because I work closely with hospitals like Tri-City hospital and Cedars Sinai, we have been able to do close to a hundred of these operations, and we’ve had great results.
