Bile passes out of the liver through the bile ducts and is stored in the gallbladder. After a meal, it is released into the small intestine. When the bile ducts become blocked, bile builds up in the liver, and jaundice (yellow color of the skin) develops due to the increasing levels of bilirubin in the blood. The possible causes of a blocked bile duct include: Cysts of the common bile duct. Enlarged lymp nodes in the porta hepatis.
If a gallstone blocks either of these ducts, the normal flow of bile into the intestine is disrupted. The muscle cells in the bile duct contract vigorously to try to move the stone, causing the pain of biliary colic. A stricture of the bile duct or a tumor also can block bile flow and cause biliary colic.
