Agreement on definition of biliary microlithiasis

Biliary microlithiasis	Literature-based findings	Expert agreement	Audience agreement
Concrement size	≤5 mm	11.54%
	≤3 mm	46.15%	–
	≥3 mm ≤5 mm	46.15%	65.3%
Imaging method of choice	EUS*	93%	–
	Bile sample centrifugation and examination by phase-contrast and polarising light microscopy	16%	–
Sonomorphology	With acoustic shadowing	96.15%

*There is an obvious bias in this voting as first, mainly EUS experts were involved in the questionaire and second we did not discriminate between findings in the CBD and the gallbladder. Transabdominal ultrasound might be the method of choice for gallbladder findings.

CBD, common bile duct; EUS, endoscopic ultrasound; GB, Gallbladder.
