I really appreciate the fact that I got to see Dr. Liu in consultation for my Zenker's diverticulum instead of a NP. Dr. Liu did a really good job in explaining and showing me what the Zenker's is and how he "fixes" it. The only thing I feel that should have been addressed was "do you have any other medical problems that may have an effect on the outcome of the Zenker's. I also have Barrett's esophagus and Schatzki's ring which has been dilated several times as well as gastric polyps. I brought paper copies of all my medical reports and my swallow tests where the Zenker's was documented AND a CD of the Images of my swallow tests and he just looked at the EGD report that documented that I do have a Zenker's and briefly at the swallow test written report that mentions the size. I thought that he probably would have liked to look at the actual Images to see the Zenker's for himself. Maybe these are not something he should be concerned about. Overall I am really happy with Dr. Liu as I was referred to him from another facility to take out what ended up being a much larger than thought, 50 mm, polyp from my colon and I did really well following this. I am looking forward to getting this Zenker's "fixed" in November.
