Might be worth a discussion with the docs to be sure they image / assess her gallbladder in the process, especially since she has had hepatic involvement.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6082629/
describes the imaging efficacy in acute gallbladder attacks and suggests Ultrasound if CT is non-diagnostic, and vice versa
BUTT ... other causes MUST be ruled out, as many issues which cause pain are not severe acute gallbladder attacks.
Biliary sludging and gallstones are two distinct but related syndromes and while all of our cancer "docs" are looking for cancer related issues ....
Just because we are cancer patients dose not mean that every pain is cancer related !" You miss more for not looking ... than not knowing !"
PLEASE ensure the docs keep looking !!
