Overview
Biliary dyskinesia is a failure of proper movement of the sphincter of Oddi.
Failure of the biliary sphincter can be distinguished from the pancreatic sphincter.
Diagnosis
History and Symptoms
Physical Examination
Laboratory Findings
The initial laboratory work-up should include: liver function tests (AST, ALT and, total bilirubin), amylase, and lipase.
CT
CT scan is not helpful in gallbladder or biliary diseases.[1]
Ultrasound
Ultrasound is required in these patients in order to exclude structural conditions such as gallstone disease or cancer. Ultrasound may be used in order to diagnose sphincter of oddi (SOD) disorders by measuring the common bile duct (CBD) diameter.
