I don't know if this will help you, but it's typical to have biopsies done whenever you have an endoscopy. In fact, your doctor would be considered incompetent if he/she did not send out biopsies for evaluation. It does usually take a week or so before biopsies come back. I'm surprised, though, that your doctor did not even mention anything to you briefly after the procedure. both times I've had an endoscopy, the doctor came to see me briefly after I got dressed. I was wacked out on drugs both times, but my husband was there too, so he usually got the whole story.
Call your doctor again. don't give up until you get a response back from him.
