Hi, I had my band done here in the states and have had 3 fills, none of which were done via fluoroscopy (spelling?). My Doctor does it in his office exactly as you described and it hasn't been a big deal, as long as he finds the port, which, shouldn't be a problem... you can feel them... i can feel mine anyway. It's no worse then drawing blood. You should be ok...
good luck !! Merideth
