Candybia - Even though I can't really speak Italian, google translate does an ok job
I have had Manometry test done, It's not the nicest thing but not as bad as people make out, you will be fine.
I would like to ask if you have looked into the LINX device/magnetic ring that prof bonavina has used. Are you considering it? I have been offered the device and am looking for as much info as possible. Anything that you can advise me on that I may have missed on an italian site would be a great help to me.
Anything I can help you with just ask.
