Abstract

Background and aims: There is limited literature on endoscopic ultrasound-guided liver biopsy (EUS-LB), a new method of obtaining liver biopsy (LB).

Methods: We conducted a retrospective study of the efficacy and safety of EUS-LB compared to percutaneous liver biopsy (PC-LB) in patients with chronic liver disease at our center between January 2018 and August 2019.

Results: Thirty patients underwent EUS-LB and 60 patients underwent PC-LB were identified (median follow-up post-LB was 8 days; interquartile range (IQR), 3-5 days). The median number of portal tracts was significantly higher in the PC-LB group (13 vs. 5; P < 0.0001). A histologic diagnosis was established in 93% of the EUS-LB group, compared to 100% in the PC-LB group (P = 0.841). Patients in EUS-LB group had significantly shorter hospital stay (median time of hospital stay was 3 vs. 4.2 h in the EUS-LB vs. PC-LB group, respectively; P = 0.004) and reported less pain compared to PC-LB group (median pain score was 0 vs. 3.5; P = 0.0009). EUS-LB were performed using a 19-gauge (n = 27) or 22-gauge (n = 3); there was a tendency towards higher number of portal tracts in the 22- vs. the 19-gauge needle group (6 vs. 5; P = 0.501). No patient in either group had significant adverse events such as bleeding or death.

Conclusion: EUS-LB is safe and is associated with less pain, shorter hospital stay, and high diagnostic yield (93%) compared to PC-LB. Randomized trials are needed to standardize the utility of EUS-LB.
