How common is it to remove a gallbladder with sludge? I have a lot of pain and high ALT/AST although these levels seem to be coming down. Pain is still very intense. No gallstones. I have had this pain for a very long time. "Attacks" in upper abdomen after eating in evening mostly. I am underweight, not able to eat a lot, and really struggling. I don't want to have a whole bunch more tests but just get the gallbladder out.
