TJLB, transjugular liver biopsy; G, gauge; PT, portal tracts.

G, gauge (translation of gauge (G) to external diameter of needle in millimetre (mm): 14 G = 2.1 mm; 15 G = 1.83 mm; 16 G = 1.65 mm; 17 G = 1.47 mm; 18 G = 1.24 mm; 19 G = 1.06 mm).

*In 14 patients with cirrhosis.

†Length per core.

‡1.2‐mm needle diameter.
