Portal hypertension has been regarded as an uncommon and late complication of primary biliary cirrhosis (PBC). 24 patients with PBC were investigated for portal hypertension. Esophageal varices were present in 20, 50, and 90 % of the patients 1, 3, and 9 years, respectively, after the onset of pruritus and/or jaundice. Portal hypertension was responsible for gastrointestinal bleedings in 11 patients; bleeding was the first clinical manifestation of PBC in two of them. Wedged hepatic venous pressure was increased in all the patients with portal hypertension whether regenerative nodules were present or absent. Portacaval shunt was performed in five patients and was well tolerated in three of them. It is concluded that (a) portal hypertension is common in PBC; (b) the intrahepatic block is of the so-called postsinusoidal type, even in patients without regenerative nodules; (c) gastrointestinal bleeding due to portal hypertension occurs in about half of the patients and may be the first manifestation of PBC; (d) portacaval shunt seems to be indicated when gastrointestinal bleeding occurs in earlier stage of the disease.
