Biliary Dyskinesia and Hyperkinesis.

Biliary dyskinesia refers to a group of functional and motility disorders of the biliary system in patients presenting with typical biliary pain, but without any visible structural abnormalities on standard imaging. The Rome IV Criteria establishes diagnostic criteria for functional gallbladder disorder (gallbladder dyskinesia and biliary hyperkinesia), functional biliary sphincter of Oddi disorder (biliary dyskinesia), and pancreatic sphincter of Oddi disorder. Many diagnostic adjuncts such as hepatobiliary scintigraphy and sphincter of Oddi manometry exist, although these results are supportive and not necessarily diagnostic for biliary dyskinesia. Surgical intervention is most successful when selecting for patients with typical biliary pain.
