Prospective Study of the Impact of Liver Biopsy Core Size on Specimen Adequacy and Procedural Complications

An American Association for the Study of Liver Diseases (AASLD) consensus document stressed the importance of obtaining sufficient liver biopsy specimens to minimize sampling errors. Many centers continue to use smaller-diameter core systems to minimize perceived complication risks. The objective of this study was to assess the impact of core gauge (18- vs 16-gauge) on specimen adequacy and procedural complications.One hundred fifty patients...
