Comparison of EUS-Guided Liver Biopsy With Percutaneous Liver Biopsy

There are several ways to perform liver biopsies, including the percutaneous route (historical gold standard) and via endoscopic ultrasound (EUS) guidance. The primary aim of this study is to prospectively compare patients undergoing EUS-guided liver biopsies to patients undergoing percutaneous biopsy. The investigators hypothesize that (1) patients who are randomized to undergo EUS-guided liver biopsy will rate themselves as having less pain in the 48 hours following the procedure, and (2) will have comparable histologic yield to a 2:1 matched cohort of patients undergoing percutaneous liver biopsies.
