question: I have had MRCP scan and got gallstones. But also found mildly dilated intraheptic biliary ducts in segment 8 and 4a returning into normal calibre of the right hepatic duct and some hypertrophy of left lobe of liver. What does this mean? I have pain in right area under the ribs and back / shoulder pain. But also gas / lower abdomen pain and floating stools. What could be the cause?
