Primary sclerosing cholangitis, the biliary tree, and ulcerative colitis.

This is the authors' abstract. We don't add key points for this paper.

EDITORIAL COMMENT It is well known that ulcerative colitis may be associated with a number of different diseases of the liver. This paper records sclerosing cholangitis as one possible mechanism of intrahepatic cholestasis. Sclerosing cholangitis is a general disease of the biliary system involving intra-and extrahepatic ducts and also the gall bladder. The diagnosis can only be made by laparotomy. The prognosis seems to be better that was originally thought.
