Brief Answer:
further liver testing
Detailed Answer:
Hi, i am sorry that you are in so much discomfort without an obvious source.
The fact that you have Crohn's and an elevated alk phos makes me think right off the bat about
Primary Sclerosing Cholangitis. An
ultrasound would not pick this up, and a
CT scan may, but it's not the best test. I would suggest an "MRCP" (special type of MRI) to take a good image of the liver and bile ducts.
However keep in mind that your alk phos was very minimally elevated, and it could just be a fluctuation of your labs.
I would suggest you getting checked for all types of liver diseases related to Crohn's such as PSC mentioned above, also
autoimmune hepatitis (by blood testing).
Pain not necessarily is from the liver, even though it is in the RUQ area. People with Crohn's can become "hypersensitive", and it is common to get "irritable bowel syndrome" as well. There are many anti-spasmodics and medications for
neuropathic pain that can be tried if nothing is found on further testing.
Another option is what is called "biliary dyskinesia", where the
gallbladder does not function properly, however looks normal on CT or ultrasound. A functional study of the gallbladder can be performed to evaluate for this (test is called Hepatobiliary scan with
CCK injection). Removing the gallbladder would solve this particular problem.
Hope that helps. let me know if you have any further questions or concerns
