Endoscopic ultrasound guided liver biopsy for parenchymal liver disease

Table 2 Comparison of percutaneous liver biopsy with endoscopic ultrasound guided liver biopsy

	PC-LB	EUS-LB
Anatomical definition	Likely improved with ultrasound guidance	Better than PC-LB and the addition of Doppler reduces complications
Imaging resolution	Lower	Higher
Diagnostic yield/accuracy	Comparable
Sampling error	Higher	Lower
Access to liver lobes	Predominantly right lobe sampling	Can easily sample both right and left lobes
Average recovery time	10 h	4 h
Technical difficulty	Lower	High
Cost	Low	High

PC-LB: Percutaneous liver biopsy; EUS-LB: Endoscopic ultrasound guided liver biopsy.
