Why would a doctor give my Dad a EGD, without using a feeding tube?

Once they put in in his throat at midnight... he pulled it out. They said it was to help him with a feeding tube, but my dad is with hospice, and I don't see them doing this. He cannot swallow anymore, not even water. Are they looking for something? He is bleeding and they have taken him off of pradaxa, with a pradaxa bind? The doctors and hospital are not very forthcoming with their answers. We have to wait for a answer, then they go ahead while we are gone to perform procedures, to me are invasive. The doctor told me they would never do an invasive procedure without calling or telling us first. But, last night at midnight, they tried twice to insert the tubing. Help!.... are they just leading us around in a circle? Also, his family dr who is in charge of hospice in this county, is always gone on vacation, or is in his room at 6:00am, knowing we are not there.
