The most common liver disease crossover with UC is Primary Sclerosing Cholangitis. I have heard of AI Hep too. Worst case scenario is liver transplant. No biggie :). Just like changing the oil on your car. I have been suspected for PSC for some years now. Been down the biopsy path and a whole lot of other stuff. Hope you don't have any of the above. Do your reasearch on AI Hep and how to dx etc before getting a liver biopsy. These are rare diseases and most Dr's only see them on a very limited basis. If you end up having it I would coordinate care with a place like Mayo Clinic etc. Best!
