Acid Reflux after Total Gastrectomy?

My father had total gastrectomy in 2003 for stomach cancer.  He's recently been having chronic throat discomfort/pain.  He's trying to find an ENT who takes medicare/medical.  In the meantime, he's only seen general family doctors.  They all have different theories, mostly acid reflux.  Can you have acid reflux if you don't have a stomach?  If so, they tell him to take antacid.  But if he is producing some acid, would it be harmful to get rid of what little acid he does produce?  Does he not need it for aiding digestion?  Any help would be appreciated.  Thank you.

If he had a total gastrectomy, there will not be any remaining acid producing cells in his reconstructed system. It's possible he may be having bile reflux, which can produce many of the same systems as acid reflux.
