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.
Currently, liver biopsy is the gold standard for determining the index of liver fibrosis in a patient with chronic liver disease, and whether the patient has progressed to cirrhosis. These biopsies are predominantly performed percutaneously. However, there are several complications related to liver biopsy, the most common of which are pain and bleeding.
There has been significant movement over the past several years to assess the utility of alternative techniques and approaches for the evaluation of liver disease. Endoscopic ultrasound (EUS) is a well-established technique for diagnostic and therapeutic evaluation of gastrointestinal and pancreaticobiliary disorders. EUS-guided liver biopsy (EUS-LB) has shown to be technically simple, safe, and provides adequate diagnostic yield for evaluation of liver disease in both children and adults. There are several advantages to EUS-LB. First, it would theoretically be less painful than the percutaneous approach, as it does not require skin puncture and also offers the comfort of sedation and analgesia. It also eliminates the need for breath hold. Furthermore, it is an image-guided approach which allows visualization and avoidance of blood vessels even 1 mm in size. Additionally, it provides an access area to a much wider segment of liver parenchyma as the entire left lobe, and the majority of the right lobe can be evaluated for possible needle puncture sites from the stomach and duodenal bulb, respectively. In addition to obtaining tissue, EUS-LB also offers the benefit of evaluating the biliary tree, gallbladder, pancreas, lymph nodes, and vascular anatomy for a more comprehensive evaluation in the same setting. Finally, in patients ultimately found to have biopsy-proven cirrhosis, it simultaneously provides the necessary variceal screening which would otherwise require an additional procedure.
The aim of this study is to prospectively perform EUS-guided liver biopsies in patients who are otherwise candidates for percutaneous biopsy. We 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 transjugular liver biopsies.

Exclusion Criteria:
Participants will be referred for liver biopsy by their hepatologist/gastroenterologist. The intervention is that these participants will undergo a percutaneous liver biopsy per standard protocol.
Procedure: Percutaneous liver biopsy
Participants will be referred for liver biopsy by their hepatologist/gastroenterologist. The intervention is that these participants will undergo an endoscopic ultrasound procedure per standard protocol. The liver will be identified, and Color Doppler imaging prior to needle puncture will confirm lack of significant vascular structures within the needle path. Liver biopsies using up to 1-2 passes from the left hepatic lobe using a transgastric approach and up to 1-2 passes from the right hepatic lobe using a transduodenal bulb approach will be performed. The participant will be observed in the recovery unit for up to 60 minutes after the EUS-LB, and discharged if no pain or signs of complication.
Procedure: Endoscopic ultrasound-guided liver biopsy
Participants will undergo endoscopic ultrasound per standard technique, with liver biopsy performed at that time.
Participants will undergo percutaneous liver biopsy per standard protocol.
