A 41-year-old female asked:

what causes your common bile duct to be dilated 12mm when you don't have a gallbladder.

Sphincter muscle : At the end of the duct, just at it's entry to the intestine. There is a circular muscle that closes off the duct when bile is not needed to digest foods. Since the liver never stops making bile, it will build up inside the bile ducts and stretch them out when a gallbladder has been removed. A stone could block the duct but will produce symptoms. The stretched open ducts happen without symptoms.

Common bile duct dilation from 10-12mm is commonly seen in those who have had cholecystectomy, especially older patients.
