Just got back from my Gastro visit. He said what's needed is the florescent light not the dye. He said as Endo units replace scopes they are getting them but of course, they're more expensive so not every hospital will be getting them right away. He did say the flat ones are alot harder to see with a normal scope but in my case he thinks the other parts of the picture that he uses to make his diagnosis do not point to my being concerned. I just hope that when I have it re-done next year they have the new ones.
