Widdly my son has had two scopes and they are just as Mother Goose has explained, no one likes their child to go under but the test itself is not too hard. The worst part for them is the gas mask so you could practice if you have a puffer and basically they put that on till they go to sleep.

I would definately ask for biopsys while you are there to rule out esinophilic osophagitis and celiac, if he is responding to the losec then this is most likely the culprit.

How much losec is he on and how do you administer it (tablet or suspension). My son is three and still refluxing and I too thought all kids grow out of it, and it is now always the case.

Good luck, if you have any questions please write back!
