perhaps both things are happening here, i.e. we are getting false stones and real stones from gallbladder and/or liver...maybe? the ducts don't seem to be flacid and large enough for 1'' stones but smaller stones could get through...also can liver stones float even though Gallstones may not? I tried this flush out of curiosity and I found big green floaters and small blondish facited sinkers...I have kept some and will see if a lab can tell us what they are...until then...chaio!
