Cholélithiase



Définition

Formation de calculs dans la vésicule biliaire. Il est le trouble le plus commun des voies
biliaires.

Physiopathologie

Survient lorsque l’équilibre entre le cholestérol, les sels biliaires et le calcium en
solution est modifié créant la précipitation de ces substances. certains facteurs comme
l’infection ou les troubles du métabolisme du cholestérol perturbent l’équilibre. La bile
sécrétée par le foie lors de cholélithiases est sursaturée de cholestérol entraînant la
précipitation de celui-ci. Il est à noter que c’est le passage des calculs dans les canaux
qui cause la DLR. La stase biliaire peut donc entraîner une cholécystite.

La cause véritable de cette pathologie est inconnue.
