When do you need surgery for an enlarged bile duct?

Surgery for an enlarged bile duct is typically indicated when there is an obstruction causing significant symptoms, such as jaundice, abdominal pain, or infections like cholangitis. Surgical intervention may also be necessary if there is a suspicion of malignancy, or if non-invasive treatments have failed to relieve the condition. Additionally, if complications arise, such as bile duct stones or strictures, surgery may be required to restore normal bile flow.
