I couldnt do it either.They requested it prior to my surgery.I have seizures and when they started placing the tube in my nose i had an aura and knew i was going to have a convulsion so we stopped i got my barrings and left.i called my g.i and he said ok. I had the surgery without the manometry however it is a very important part of pre op. I prayed every day & nite asking god please let my esphagus be my soldier and hold me up. i have no swallowing issues as of yet, just a few dumb spasms fro the dumb organ
take care
