Overview
Brief Summary
This study is to evaluate and directly compare the technical success, tissue quality, diagnostic efficacy and safety profile of Percutaneous and Endoscopic Ultrasound-guided Liver Biopsy.
Detailed Description
Liver biopsy (LB) is essential for the diagnosis and evaluation of a variety of hepatic conditions, such as grading/staging of chronic liver disease secondary to alcohol, non-alcoholic steatohepatitis, viral hepatitis, hemochromatosis, Wilson's disease, cholestatic liver disease, as well as in elucidating the etiology of elevation in liver tests.1 Since it was first performed in 1883, percutaneous (PC) liver biopsy has become routine practice and is usually performed under the guidance of real-time imaging using transabdominal ultrasound (US) or computed tomography (CT).1,2 However, in recent times, liver biopsy has been increasingly performed via transgastric or transduodenal routes under endoscopic ultrasound (EUS) guidance. The perceived advantages of performing EUS-LB compared to PC-LB are the ability to simultaneously assess other organs such as common bile duct and pancreas, access to both left and right lobes of the liver and the routine use of conscious sedation during EUS procedures.3 Although single arm cohort studies and retrospective comparative studies assessing the technical success, tissue quality and safety of these different liver biopsy modalities exist, currently there are no randomized trials comparing PC and EUS-guided LB.4-7

Outcomes
Primary Outcomes
Diagnostic adequacy of the tissue sample
Time Frame: 24 hours
The primary outcome of the randomized trial is to compare between EUS-LB and PC-LB, the rate of procurement of diagnostically adequate specimens, defined as the presence of both maximum specimen length ≥ 25mm AND total no. of complete portal tracts ≥ 11.
Secondary Outcomes
- Pain scores(24 hours, 1 week, 30 days)
- Procedure duration(24 hours)
- Rate of adverse events(24 hours, 1 week, 30 days)
- Procedural costs(30 days)
- Specimen length(24 hours)
- Portal tracts(24 hours)
- Rates of specimen adequacy(24 hours)
- Cross over(1 week, 30 days)
