Can you explain what biliary dyskinesia is?

Yes: The gall bladder stores and concentrates bile made by the liver to help digest and absorb fats. The gallbladder has nerves which control ejection of the bile when needed. In biliary dyskinesia the contraction of the gallbladder is abnormal. The duct cointracts first and then the gallbladder. So the gallbladder is trying to eject bile through a closed tight opening. This causes pain without stones.

Biliary dyskinesia: Biliary dyskinesia refers to altered tone of the sphincter of oddi. It causes the coordination of contracture of the biliary ducts or the emptying of the biliary tree. It is often a symptomof of gall stones, acute or chronic pancreatitis, chronic inflammation or other GI disorders.
