Biliary dyskinesia

Key points

Symptoms of biliary colic without gallstones

Controversial diagnosis in paediatric population

Cholecystokinin (CCK) stimulated HIDA scan

If 30 minute gallbladder ejection fraction is l<35-40% it can be suggestive of biliary dyskinesia

Cholecystectomy resolves symptoms in around 70% (large range of results)
