Core Tip
Core tip: Pancreaticobiliary reflux (PBR) is an important pathologic state that can cause biliary malignancy. PBR can occur regardless of whether the patient has pancreaticobiliary maljunction (PBM) or not. Although it has long been possible to diagnose PBM by various imaging modalities, PBR without PBM has remained difficult to assess. Therefore, the pathological features of PBR without PBM have not been yet fully elucidated. Lately, a new method of diagnosing PBR without PBM has appeared, and the features of PBR without PBM should soon be better understood.
