ABSTRACT
BACKGROUND: Traditionally, liver biopsy has been the gold standard for fibrosis staging. However, it is an invasive, expensive and uncomfortable procedure that is associated with the risk of complications. Thus, non-invasive methods such as shear wave elastography (SWE) have been developed as potential alternatives to liver biopsy. The aim of this study is to evaluate the diagnostic performance of SWE in pediatric patients with liver fibrosis, specifically in a group of Algerian children and to determine whether this method can be a reliable alternative to liver biopsy.
METHODS: This prospective, descriptive, monocentric study evaluated the non-invasive diagnostic performance of 2D-SWE in assessing liver fibrosis in pediatric patients. The assessment was carried out using various statistical methods, including Spearman’s correlation coefficient, Kappa concordance coefficients, regression analysis, as well as the calculation of area under the receiver operating characteristic (AUROC) values and corresponding cut-off points based on the receiver operating characteristic (ROC) curve.
RESULTS: Our study found that 2D-SWE is strongly correlated with liver biopsy in estimating liver fibrosis in children, with a correlation coefficient greater than 0.8. Furthermore, the Kappa correlation coefficients exceeded 0.8, indicating a strong agreement between 2D-SWE and liver biopsy results. The AUROC value was not less than 0.9 for significant fibrosis and above (≥ F2), indicating that it has satisfactory diagnostic performance in detecting liver fibrosis in children.
CONCLUSION: 2D-SWE shows promise as a non-invasive method for evaluating liver fibrosis in children, offering a potential alternative to liver biopsy. Larger studies are needed to substantiate the findings of this study and to confirm the accuracy and reliability of 2D-SWE for assessing liver fibrosis in children.
