Sherry,
I had a PEG and I probably would again. To be honest, I can't even imagine how uncomfortable a naso-gastric tube would be. I would strongly suggest you have your dotor stick that horrible thing in his nose and see how much he prefers it then.
Not to muddy the water too bad but I read a study (can't remember which voume of ANNALS it was in) about more issues with the naso-gastric versus the PEG. Besides, who wants to walk around with a tube hanging out of their nose for a few weeks/months?
