Both the Miami-criteria⁶ and Paris-criteria⁷ for pCLE evaluation in the pancreatobiliary system

Criteria suggestive for malignancy	Criteria suggestive for benign lesions/strictures	Inflammatory conditions
Thick, dark bands (>40 µm)	Thin, dark bands (branching)	Vascular congestion
Thick, white bands (>20 µm)	Thin, white bands	Dark granular patterns with scales
Dark clumps		Increased interglandular space
Epithelium (villi, glands)		Thickened reticular structure
Fluorescein leakage
