Abstract
Purpose of Review
EUS-guided liver biopsy (EUS-LB) is being used with increased frequency to perform parenchymal liver biopsy. Evolution of the technique can now achieve excellent liver tissue cores. This review covers important developments in this procedure.
Recent Findings
Clinical studies have recently demonstrated that the 19G EUS core biopsy needle is superior to non-core needles for liver tissue acquisition. In addition, wet suction provides more robust tissue samples than dry suction. Heparin priming of the needle (instead of saline) can prevent blood clogging within the needle lumen. A 1-hour recovery time after the EUS-LB is sufficient in almost all cases. The EUS-LB can deliver bilobar biopsies, which can decrease sampling error. Patients who need a liver biopsy in addition to an endoscopy or EUS are best served by the EUS-LB, as the combination procedure saves time and cost.
Summary
The EUS-LB is a safe and effective means for procuring good liver core biopsies. Incremental improvements in technique have increased quality of the resulting specimen. Future directions of this technique are discussed.
