Percutaneous liver biopsy - What is the current approach? Results of a questionnaire survey

The technique of performing liver biopsy varies among physicians, even with in the same practice. In an attempt to determine whether gastroenterologist s/hepatologists differ in their approach compared to radiologists, we surve yed a nearly equal number of physicians in the Washington, DC, USA, metropo litan area with respect to 26 variables. While the technique can vary consi derably, relatively few differences were seen between the groups. Only abou t half of gastroenterologists and hepatologists use ultrasound guidance, a biopsy, gun, and conscious sedation; radiologists routinely used a biopsy g un and conscious sedation and rarely require an overnight stay.
