BACKGROUND AND AIMS: Diagnostic tools for nonalcoholic fatty liver disease (NAFLD) detection and prognostication are limited, with histology remaining the criterion standard. We evaluated the feasibility and safety of EUS-guided liver biopsy (EUS-LB) sampling in NAFLD staging.METHODS: In a prospective cohort of NAFLD patients with steatohepatitis and early liver fibrosis based on magnetic resonance elastography (MRE), EUS-LB sampling procedures were performed using a 22-gauge fork-tip core biopsy needle. Samples were evaluated by a blinded pathologist. Total aggregate sample length (TASL), number of complete portal triads, ability to calculate NAFLD activity score, ability to stage liver fibrosis, and ability to provide enough core liver tissue for lipidomics analysis were evaluated. Performance of EUS-LB sampling was compared with MRE.RESULTS: Forty-one EUS-LB samples were obtained. The median TASL was 2.4 cm (interquartile range, 2.00-2.75). The median number of complete portal triads per TASL was 26 (interquartile range, 7-62). Of the samples, 100% were adequate to convey NAFLD activity score and fibrosis stage. All samples provided enough core liver tissue to allow the application of lipidomics testing. A significant positive linear association between EUS-LB sampling-detected fibrosis and MRE-detected fibrosis was observed (r = .469, P < .005). Compared with MRE, EUS-LB sampling established early fibrosis in 13 cases that MRE classified as normal. EUS-LB sampling-related adverse events occurred in 7% and were restricted to postprocedural pain.CONCLUSIONS: EUS-LB sampling is a viable technique for full NAFLD evaluation and may be superior to MRE in establishing the diagnosis of nonalcoholic steatohepatitis with early fibrosis.
