[Primary sclerosing cholangitis].

A case of intermittent cholostatic icterus has been observed at the Civil Hospital of Castellamonte. Clinical and laboratory examinations did not permit precise diagnosis, hence the decision to carry out exploratory surgery. The finding was hepato-choledochic fibrosis with severe stenosis of the lumen and patency of Vater's tubercle, with no calculosis or previous bile way operations. Transcholedochic and transpapillary biliary drainage was therefore performed with a T tube. The patient is in good condition about two years after the operation and cholangiocarcinoma can be excluded. It is therefore considered that the case can be classified as a "primary sclerosing cholangitis".
