So how could you define these people like expert in this field?

That is a really good question, um, because we often ask ourself, "How do you define a surgical expert in any kind of field?" So you can use the years of experience, either in open or minimally invasive surgery.

You can use the volume of surgeries that they operate.

You can use whether they are just upper GI surgeons or, for example, like in Germany, we don't have s- subspecialties like, um, upper GI surgery, but, uh, we have general surgeon who, um, perform a lot of, um, upper GI procedures.

So that was also not one criteria that we took when defining experts, so we took all of it basically, and we took of course in consideration their international and national recognition in the field of upper GI surgery.

Um, so yeah, we took the volume of the hospital, volume of the surgeon, and the international recognition in upper GI surgery.

And you're right, there are two, um, experts that haveThree to five years, uh, experience in minimally invasive surgery.

Is there anything you would like to share or, um, promote in, uh, through this episode?
