Abstract
OBJECTIVE. The purpose of this study was to compare the outcome of sonographically guided core biopsies performed with the 14-gauge automated gun with the outcome of those performed with the 11-gauge vacuum-assisted device. Outcome was defined in terms of missed tumors, the need (both immediate and delayed) for a second biopsy, histologic underestimation, and complication rates.MATERIALS AND METHODS. We retrospectively reviewed all sonographically guided core biopsies performed between January 1997 and August 2001. Before February 2000, biopsies were performed using the 14-gauge automated gun and after that time, with either the 14-gauge automated gun or the 11-gauge vacuum-assisted device. During the study period, 181 biopsies were performed with the 14-gauge automated gun and 100 with the 11-gauge vacuum-assisted device.RESULTS. The histologic results of the core biopsies were similar for the group who underwent biopsy with the 14-gauge automated gun and the group who underwent biopsy with the 11-gauge ...
