Gallstones disappeared?!

Hi friends,

So I’m currently at my second admission to the ER for suspected gallstones and pancreatitis.

I was admitted a month ago for pancreatitis and was told my gallbladder was full of stones and needed to be removed.

Today I’ve just been told that there is no evidence of gallstones anywhere. The thickening and fluid I had also gone. I had an ultrasound and a ct with contrast.

Can gallstones just disappear?! I’m confused?
