Abstract

Purpose

The goal of this study was to compare the diagnostic accuracy, complication rate between 11 and 8 gauge Mammotome probe during ultrasound-guided Mammotome biopsy.

Methods

Sixty eight patients who showed breast mass in sonography were included in this study. Statistical comparisons between the 11 and 8 gauge group were done.

Results

75 biopsies were performed using the Mammotome biopsy system guided by sonography. 63 LESIONS(84.0%) had benign pathology and 12 lesions(16.0%) were malignant. 49(65.3%) of these biopsies were performend with the 11-gauge Mammotome probe, and 26(34.7%) with the 8-gauge probe. Complications such as pain, bleeding , hematoma and skin discoloration were compared between 11 and 8 gauge group. There were nostatistically significant differences in complications such as pain, bleeding, hematoma and skin discoloration. All complications had no significant difference between 11 gauge group and 8 gauge group.

Conclusion

The ultrasound-guided 8 gauge Mammotome biopsy system is as safe as ultrasound-guided 11 gauge Mammotome biopsy system.
