Abstract
Transient elastography (TE) has received increasing attention as a means to evaluate disease progression in chronic liver disease patients. In this study, we assessed the value of TE for the prediction of fibrosis stage in a cohort of pediatric patients with nonalcoholic steatohepatitis. Furthermore, TE interobserver agreement was evaluated. TE was performed in 52 consecutive biopsy‐proven nonalcoholic steatohepatitis patients (32 males, 20 females, age 13.6 ± 2.44 years). The area under the receiver operating characteristic curves for the prediction of “any” (≥1), significant (≥2), or advanced fibrosis (≥3) were 0.977, 0.992, and 1, respectively. Calculation of multilevel likelihood ratios showed that TE values Conclusion: TE is an accurate and reproducible methodology to identify pediatric subjects without fibrosis or significant fibrosis, or with advanced fibrosis. In patients in which likelihood ratios are not optimal to provide a reliable indication of the disease stage, liver biopsy should be considered when clinically indicated. (HEPATOLOGY 2008.)
