[Surgical problems of the primary sclerosing cholangitis (author's transl)].

: The characteristics of the primary sclerosing cholangitis are a diffuse inflammation with fibrous thickening and narrowing of the biliar ducts. Two observations replying to strict characteristics are related. From attacks of angiocholitis, the disease generally progresses till a parmanent icterus and death occurs in a state of biliar cirrhosis. In the liver, the micro pathology consists in fibrous rings constricting the segmentary interlobular ducts. The diagnostic is mainly difficult and the prognostic is fatal in average time of 4 years of evolution althought we used corticoids that were administrated by local method as well as in the classical general way.
