Change of the hilar periportal space in the patients with chronic hepatitis B and liver cirrhosis after hepatitis B / 重庆医学

ABSTRACT

Objective To investigate thickness of the hilar periportal space and caudate-right lobe ratio in the patients with chro-nic hepatitis B and liver cirrhosis after hepatitis B .Methods Eighty-four patients who were clinically and histologically diagnosed with chronic hepatitis B or cirrhosis and 18 healthy subjects without history of liver disease underwent abdominal MRI .The rela-tionship among liver fibrosis degree ,hilar periportal space and caudate-right lobe ratio were observed .Results There was signifi-cant correlation between the hilar periportal space and hepatic fibrosis for chronic hepatitis and cirrhosis (rs = 0 .546 ,P< 0 .01) . There was significant difference between S2 and S3 for thicknesses of the hilar periportal space(P<0 .01) ,and no significant differ-ence among S3 ,S4 and cirrhosis(P=0 .188) .A cutoff value of 9 mm for the hilar periportal space had a sensitivity of 85 .37% and a specificity of 76 .79% for a diagnosis of hepatic fibrosis with S3 or higher .There was no significant correlation between the caudate-right lobe ratio and hepatic fibrosis(rs = -0 .155 ,P=0 .119) .Conclusion Thicknesses of the hilar periportal space increase gradu-ally with hepatic fibrosis in patients with chronic hepatitis B and cirrhosis ,with a high sensitivity and specificity for a diagnosis of hepatic fibrosis with S3 or higher .
