Feasibility of Fibroscan in Assessment of Hepatic Steatosis and Fibrosis in Obese Patients: Report From a General Internal Medicine Clinic.

Background In metabolic associated fatty liver disease (MAFLD) vibration controlled transient elastography (VCTE) by Fibroscan has emerged as a non-invasive diagnostic tool for the measurement of controlled attenuation parameter (CAP) and liver stiffness measurement (LSM), which are surrogate markers for hepatic steatosis and fibrosis, respectively. However, obesity constitutes a limitation in terms of creating unreliable examinations due to increased skin to liver capsule distance. Here, we aimed to investigate the feasibility of VCTE in the evaluation of hepatic steatosis and fibrosis in obese individuals. Methods A total of 126 consecutive obese patients (body mass index ≥30 kg/m2) without a known history of MAFLD enrolled in the study. We performed CAP and LSM measurements and calculated Fibrosis-4 Index for each patient and included data of those patients to the analysis, from whom valid measurements were able to be taken. Results Reliable VCTE measurements were able to be obtained in 122 patients (97%), from those in 34 patients with M and 88 patients in XL probe (median age: 50 [18-75], 45 males and 77 females). In 1 patient VCTE failed to take any measurements and in 3 the measurements were classified as unreliable. The mean CAP value was 323 ± 48 dB/m and the median LSM value 5.3 [1.8-34.3] kPa. Conclusion CAP and LSM assessments by Fibroscan are reliable diagnostic tools for the early diagnosis of hepatic steatosis and fibrosis in obese individuals.
