Biliary dyskinesia usually relates to the sphincter of oddi and gallbladder dysfunction. This is the muscular valve that regulates the flow of bile into the duodenum.
Acalculous cholecystopathy is often called biliary dyskinesia particularly by surgeons. The characteristics of Acalculous cholecystopathy is pain in the right upper quadrant 30-60 minutes after meals, usually lasts 1-4 hours, typically does not radiate, and is often exacerbated by greasy and spicy foods.
Biliary dyskinesia has the typical symptoms of gallbladder pain. Pain in the centre of your abdomen, below your breastbone and above your bellybutton and the upper right of your abdomen, with the pain travelling towards your shoulder blade. The pain is constant, dull and is not relieved when you go to the toilet, pass wind or are sick. The pain can be triggered by eating fatty foods and it may wake you up during the night.
Gallbladder removal doesn't always cure these problems and is less effective than for gallbladder disease.
