Rome IV Diagnostic Criteria for Functional Gallbladder Disorder
Use in patients with symptoms characteristic of typical biliary pain as defined by Rome IV criteria with gallbladder present.
Supportive criteria such as low ejection fraction on gallbladder scintigraphy (<40%) and normal liver enzymes, conjugated bilirubin, and amylase/lipase can aid in diagnosis.
Do NOT use these criteria in patients with:
Atypical symptoms for biliary colic (mild, transient, constant, daily).
Visualized cholelithiasis or microlithiasis/sludge on ultrasound or endoscopic ultrasound (EUS).
Structural abnormalities, especially biliary dilation or liver enzymes not explained by other cause: should consider EUS or magnetic resonance cholangiopancreaticography (MRCP).
