ABSTRACT
BACKGROUND/PURPOSE: Endoscopic ultrasound-guided liver biopsy (EUS-LB) is a novel liver biopsy technique. We aimed to evaluate the efficacy and safety of EUS-LB in comparison with percutaneous liver biopsy (PLB).
METHODS: This retrospective study evaluated the safety and efficacy of EUS-LB using a 19-gauge fine needle biopsy (FNB) needle compared with PLB using a spring-loaded 16-gauge needle in patients with diffuse liver disease at our hospital from April 2017 to December 2020. The primary outcomes included the total hepatic tissue surface area and the total number of portal tracts. Secondary outcomes included the success and adverse event rates.
RESULTS: Twenty patients each underwent EUS-LB and PLB. There was no statistical difference in the sum of liver tissue surface area (22 mm2 vs. 22.6 mm2 , P = 0.910) and the total number of portal tracts (29 vs. 25, P = 0.916). The success rate was 95% (19/20) for EUS-LB and 100% (20/20) for PLB (P = 1). There were two adverse events in the PLB group but none in the EUS-LB group (P = 0.487).
CONCLUSIONS: EUS-LB using FNB has an optimal tissue yield and success rate and is safe compared to PLB. Thus, EUS-LB may be a new alternative to PLB.
