Pathogenesis of biliary pancreatitisPathogenesis of biliary pancreatitis

Acute biliary pancreatitis (ABP)is triggered by obstruction of the ampulla of Vater

by migrating or impacted stones

Diagnosis of ABPDiagnosis of ABP

Diagnosis of ABPDiagnosis of ABP

o Paino Elevated enzymes

- lipase better than amylase- no specific cut-off, 2-3 x N ?

o Imaging studies- usually not necessary- US not perfect (intestinal gas)- CT should not be done within 72h if not for differential diagnosis

Determination of biliary etiologyDetermination of biliary etiology


o Elevated liver function tests (~ 2 x N)o Gallstones or sludge (?)o Dilated CBD (> 8 mm)o ERCP (added value):

- small CBD stones in non-dilated CBD- endoscopic signs of stone passage- biliary microlithiasis

CBD imaging in ABPCBD imaging in ABP

o Abdominal US not sensitive enougho MRCP

- small (especially impacted) stones may be missed- air bubbles may give false+ results- fluid collections may obscure CDB in severe cases

o EUS- may be not readily available 24/24h (ES delay?)- perfect when ERCP fails
