ABSTRACT

Purpose：To probe into the technological advantage and the complication of US-guided automatic biopsy (US-GAB).

Methods：3560 patients who performed USGAB were analysed retrospectively. The relations between sampling suc-cessful rate with lesions’character , position and operating doctors were obtained. And the ratio of complications was studied.

Results：The biopsy successful rate was 97.8%. The biopsy successful rate was independent of lesions’character , positionand operating doctors. The ratio of the severity complication was only 0.12%.

Conclusion：US-guided automatic biopsywas a good sampling method with high sampling successful rate , operating facility , high histological diagnostic accuracy and low ratio of complication.
