What is cholangitis?
Inflammation of the billiary tree
What is hepatitis?
Presence of inflammatory cells
What is cholecystitis?
Inflammation of the gall bladder
What is cholangiohepatitis?
Inflammation centred on the billiary tract and extending into the parenchyma
What is chronic hepatitis in dogs?
COMMD1 mutation in bedlington terriors, impaired copper excretion
* autosomal recessive presents with progressive liver failure
* can develop into a haemolytic crisis if copper is released into systemic circulation
What is lobular dissecting hepatitis?
Sinusoidal inflammation and fibrosis in young dogs, aetiology is unknown
What commonly causes cholecystitis
uncommon, most likely due to a bacterial reflux from the gut via bile ducts or haematogenous
What is cholangiohepatitis?
ascending bacterial infection from gut, rarely descending
rapidly causes death via septicaemia
Chronic leads to fibrosis and billiary proliferation
What is neutrophillic cholangitis in cats?
Common, a part of triaditis
What is lymphocytic cholangitis in cats?
Slowly progressive, lymphoid ifiltrates and portal fibrosis
believed to be immune mediated
