All it means is that your doc is saying you're having pain in the upper right quadrant that resembles the pain and discomfort felt when one has gallbladder issues or perhaps stones. I don't know if you've been tested already or are going to be tested, but this is typical 'medical shorthand' for pain/discomfort, and he's indicating the possible location - gallbladder area.
What report is it on?? I believe it is pain caused by bile reflux. But I think it can also be a general term to mean pain caused by a biliary problem?? So what type of tests have you had, what are your symptoms and did it say more then just biliary colic??
