Yes. The stents are uncomfortable, and they will move. I had several migrate into my stomach. I passed one and didn’t know it. I went to Mayo in Phoenix. My GI doctor in Ft. Wayne was very familiar with it but the hospital he was associated with could not provide the dilator. If you decide to move forward with Mayo in Phoenix contact Dr. Allon Kahn. He is the director and an outstanding doctor and just a great person all around.
