Abstract:
Objective To investigate the probability of assessment of hepatic fibrosis for liver transplantation using model for end-stage liver disease(MELD) by comparing the correlation of MELD score with Ishak pathological grading method. Methods Fifty-eight patients who underwent liver transplantation because of end-stage liver disease from February 2006 to September 2006 were performed quantitative hepatic fibrosis evaluation using computer-assisted digital image analysis. Pathological diagnosis according to the Ishak modified score was also performed. MELD scores were calculated using the original formula based on the clinical examination data collected on the admission days. The correlations among the image analysis method, Ishak grading and MELD scoring method were analyzed using the Spearman's rank correlation analysis. The linear relationship between the MELD scores and the degree of hepatic fibrosis shown from linear regression analysis was used to define the reference criterion. Results The hepatic fibrosis area ratios of the 58 patients were between 23.2 % and 88.4 % with average of 56.7% by computer-assisted digital image analysis. The MELD scores on the admission clays were between 11 and 38 with average of 22.85±9.32. The semi-quantitative Ishak classification showed that there were 0, 2, 7, 12, 18, 12, and 7 cases in each of the 7 grades respectively, the higher the grade the higher the hepatic fibrosis area ratio and the higher the MELD scores. Spearman rank correlation test indicated that there was significant correlation among these three methods(P ＜ 0.01). Linear regression analysis showed that there was a linear relationship between the MELD scores and the degree of hepatic fibrosis. Conclusions Computer-assisted digital image analysis can evaluate objectively the hepatic fibrosis degree and it is significantly correlated to the MELD system. Hepatic fibrosis degree can be evaluated by MELD scores.
