Hey Meka, how are you feeling? I am dealing with the same thing. I hope you are well.
Hello and hope you are doing well.
The bile duct is dilated if there is a distal obstruction to the duct. This can happen with gall stones or tumors. To determine the cause a ERCP (endoscopic retrograde cholangio-pancreatiogram) may be needed. During this test, stones can be removed from the bile duct, tumors can be biopsied and the obstruction can be relieved. Alternatively, an MRI scan of the bile ducts can further determine the cause of dilated bile duct.
Hope this helped and do keep us posted.
