Liver biopsies were carried out using three different needles, a Vim‐Silverman needle 2.5 mm in outer caliber, an 18‐Gauge (18G) Majima needle, and a 17‐Gauge (17G) Majima needle. The biopsies were obtained from nearby locations on the liver surface under laparoscopic observation, to ascertain differences in histological diagnosis according to the size of the biopsy specimen. The biopsy specimens obtained with the Vim‐Silverman needle were wider than those obtained with the other two needles. The agreement in histological diagnoses of the liver, obtained with the Vim‐Silverman needle versus the 18G Majima needle, was 26.0%, while that between the Vim‐Silverman needle and the 17G Majima needle was 40.0%. Histological diagnosis tended to be underestimated in small biopsy specimens in advanced chronic liver diseases. A questionnaire survey, conducted in 92 hospitals affiliated with Okayama University Medical School, revealed US‐guided liver biopsy to be the practice of choice in 57 of 92 (62.0%) hospitals, and 18G needles were used in US‐guided liver biopsy in 35 of 78 (45.2%) hospitals.
