I might need an endoscopy (tube down throat), can the doctor do that without getting an unfill or will I have to get a complete unfill for this procedure?

Call your band doctor on this!

I agree; ask your banding surgeon.

I had to be completely unfilled.

You will need to be unfilled it they need to see more than your esophagus or pouch. Lower stomach would definitely require an unfill.

had 2 endoscopes in the last 2 months - no unfill needed.

I had 2 endoscopys and did not need an unfill............
