Abstract

BACKGROUND AND AIM: The Baveno VI Consensus recommends repeating examination in patients with high liver stiffness measurement (LSM) by transient elastography to reduce false-positive diagnosis of advanced liver disease. We tested whether repeating transient elastography can increase the overall diagnostic accuracy. METHODS: Ninety-seven patients with non-alcoholic fatty liver disease who underwent two FibroScan examinations within 6 months prior to liver biopsy were evaluated. An LSM cut-off of 7.9 kPa was used to exclude F3-4 fibrosis. RESULTS: Seventy-eight patients had high LSM at baseline, among whom 27 had low LSM on repeated testing; only four had F3 and none had cirrhosis. In contrast, 31 of 51 patients with high LSM at both examinations had F3-4. Nineteen patients had low LSM at baseline; none of them had F3-4 regardless of the second LSM results. If we took LSM <7.9 kPa at either examination as sufficient to exclude F3-4, the negative predictive value remained high at 91%. The positive predictive value for F3-4 increased from 45% in patients with high LSM at baseline to 61% in those with high LSM at both examinations. Sensitivity analysis using different cut-offs yielded similar results, with 76% of patients with LSM >12 kPa at both examinations having F3-4. CONCLUSIONS: Transient elastography is a highly sensitive screening test to exclude F3-4 fibrosis in non-alcoholic fatty liver disease patients. One-third of patients with high LSM may have normal results on repeated examination. By repeating examination in cases with high LSM, one may spare patients from unnecessary liver biopsy.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
