Efficacy and Safety of Percutaneous Liver Biopsy With Needle Tract Plugging on Outpatient Basis

Overview

A prospective, randomized, two-arm, single-center study to compare efficacy and safety of percutaneous ultrasound-guided liver biopsy of conventional method (multiple liver punctures) versus coaxial method followed by needle tract plugging.

Adult patients who are referred for the ultrasound-guided percutaneous biopsy of focal liver lesion (larger than 1cm) to obtain three or more tissue cores are eligible for this study. Exclusion criteria are as follows: 1) unable to approach a target lesion under ultrasound-guidance; 2) severe coagulopathy; 3) unable to discontinue anticoagulant/antiplatelet medications for the duration proposed by 2019 Society of Interventional Radiology guidelines; 4) co-presence of amyloidosis, large amount of ascites, or acute hepatobiliary infections. All enrolled patients will be randomized into either the conventional group or coaxial/plugging group. The conventional group will undergo percutaneous liver biopsy for multiple tissue cores through multiple punctures of the liver capsule. The coaxial/plugging group will undergo percutaneous liver biopsy using a coaxial needle (single puncture of the liver capsule), which will be plugged by gelatin particles after obtaining multiple tissue cores. The biopsy will be performed on outpatient basis regardless of the randomized group, and the patients will be discharged after two hours of observation. The rate of biopsy-related complications including bleeding (minor and major) and diagnostic yield will be compared between the two groups.
