00:20:56 TODD D. TILLMANNS, M.D.: We have another question here that was sent in. It asks who can have robotic surgery. Do you want to address that? Okay, well I think we don't generally put limits on patients that can have robotic surgery. I think they're pretty much the same as standard laparoscopy, but one of the things we actually have found is that we are able to push the limits in more obese patients, people that are a little bit heavier than others, because your visualization is so good, because you can see so well, and the instruments allow you to do things that you normally could not do even with standard laparoscopy I think. So you don't have to many limits. 00:21:33 DILJEET K. SINGH, M.D.: Yeah, and I think even -- here's where comparing the robotic surgery to open surgery is the most interesting. So I guess we're getting a quick peek at the anesthetic team. That's for Johnny, who has that questions, I think. But getting back to this question of who's eligible. In a lot of ways, the things that limit us in terms of standard open surgeries, it's long been known that it's sometimes difficult to access lymph nodes in patients who are heavy enough that we can't reach them, so to speak, in an open surgery. We know that for endometrial cancer, the main risk factor is being overweight, so this is a common situation that gynecologic oncologists and our patients find ourselves in talking about. So robotics has, I think, really opened the door to providing people who are overweight and so at risk for this cancer with what we'd consider the best possible care where we can do things like check lymph nodes and make the best treatment decisions. 00:22:31 TODD D. TILLMANNS, M.D.: Yeah, I think it's very true. One of the things that we wanted to bring up as well is to look -- I'm not sure if we can do this in the other room, if we can look below it, at Dr. Lowe's feet while he's operating. I'm not sure that's even possible. There's a set of pedals that he's using -- there you can see them right there. At his right feet right there, he's using what's called a monopolar cautery and he's pushing down on that right now with a scissors, and then the bipolar cautery which is right next to that and that runs through the instruments that you see in his left hand, the one that's not moving, and he can use bipolar cautery just as he did just now. Just to the left of that bipolar cautery pedal is the focus where he can focus the camera in and out if he needs to. 00:23:22 DILJEET K. SINGH, M.D.: I guess we can't get a view of it. 00:23:23 TODD D. TILLMANNS, M.D.: Yeah. And then just to the left of that there are two other pedals. Those pedals -- one of them allows him -- it's called a clutch pedal -- allows him to keep his inside the robot in the same place while he moves his hands outside where he's at the surgeon's console. So if he's in a place where he's moved his hands as far as he can move them, he pushes down on that pedal, you can see the clutch pedal on the farthest level right there. What he can do is actually he can -- it freezes the instruments inside the patient, he can move them wherever he wants. The pedal right next to that is the camera pedal, so he can move the camera around. As you can see, he can move it wherever he wants. There he just did it just there. So that's kind of how he controls a lot of the fine movements that you see. 00:24:07 DILJEET K. SINGH, M.D.: You know, and I think looking at those pedals sort of reminds us again what are the things we really appreciate about robotics and how that allows us to treat patients. The ability to constantly focus and move the camera is something we don't even think
