immune related diseases related to biliary tree (2)
Primary and secondary sclerosing cholangitis
what is primary sclerosing cholangitis
chronic inflammatory disease of entire biliary tree
t/f sclerosing cholangitis more common in men
true
what is commonly seen with primary sclerosing cholangitis? (1)
inflammatory bowel disease - colitis
80% of pts
T/F
the eitology is not known in primary sclerosing cholangitis, while it is known in secondary
true
what is cholangiocarcinoma
malignant growth in one of the ducts that carries bile from liver to small intestine
what is the classification based on in cholangiocarcinoma
anatomic location in liver
T/F prognosis is good with cholangiocarcinoma
false
most common to least common cholangiocarcinoma
60% - Hilar (Klatskin’s tumour)
30% - distal CBD
10% - peripheral
location of Klatkins tumour
porta hepatis
symptoms of Klatkins tumour (4)
- jaundice
- pruritis (itchy skin)
- increased LFTs
- nodes
what is the second most common primary malignancy of liver
intrahepatic cholangiocarcinoma
t/f
cholangiocarcinomas are generally hypovascular masses
true
how is intrahepatic cholangiocarcinoma differentiated from HCC
presence of ductal obstruction
polypoid masses characteristic of
distal cholangiocarcinoma
What can cholangiocarcinoma be confused with
mets
mets can affect which ducts
intrahepatic and extrahepatic
Mets to biliary tree primary sites (3)
breast
colon
melanoma
what is the HIDA scan
measures GB ejection fraction/tracks flow of bile from liver to small intestine
