### input:
Tan colored stools and diarrhea for 6 weeks. I have been on Vicoden for 5 months until the last 2 weeks due to cutting off 2 fingers, so also a couple of antiobitics during that time. Cipro and Amox. What I have had done: metabolic panel, so ALP,  ALT, AST, Lytes, Glucose, BUN, GFR, CBC, food allergy testing, H Pylori, C Difficile toxins, O&P ( X2 - 2 weeks apart, Giardia Elisa, Stool culture X2 , 2 weeks apart - all normal. Then a normal CT scan just completed. I am craving dairy and fat - and I am usually on a low fat diet, fish, vegetables etc. So I have an appt on Monday but I am at a loss. Questions; Would the CT scan show a gall bladder obstruction? Am I missing something? Something in the liver that the enzymes are not showing nor the  CT scan? Thanks I would like an opinion on what I am maybe not seeing before I go to the Doctors.

### output:

Hi.to answer your question, the test with the highest sensitivity in showing gallbladder or any hepaticopancreaticobiliary tree obstruction if your primary consideration are stones, is ultrasound; MRCP if tumor lesion is considered. But prior to doing so, it is best if you consult with a doctor first, preferably a general surgeon or a gastroenterologist, for physical examination and clinical evaluation. Other diagnostics (such as bilirubin, liver function tests, etc.) and management (medical and/or surgical if indications are found) will be directed accordingly. Hope this helps. Good day!!~ Chat Doctor.
