OMG that's horrible!! I am so sorry you guys had to go through all that just to get no useful information in the end.

Your doctor's office sounds really bad. There is no other place for healthcare?
I had a pretty awful time with my doctor's office today, too. I called them 3 times before work and got the answering service all 3 times. I called AFTER they were supposed to be open, too! Apparently they don't turn the phones on until they are darn good and ready, even after they are open. Then I called them repeatedly after I got off work and it took me over 2 hours to finally get the office. All I needed to know was what day my doctor's appointment is next week! If you miss an appointment they charge you $50 before they will see you again. I was pretty furious. What if I had been unable to get ahold of them and my appointment was on Monday morning? There is no way I would have paid them $50 for missing an appointment when it took me all day to even get through to their office. grrrr.
I hope the hospital can give you a much better explanation of your results on Monday. What if it's your gallbladder neck and not actually your gallbladder itself? Just saying it's working at 69% is not an answer. I just hate that you got the runaround over this.
