The efficacy and safety of a biopsy gun was evaluated for performance of the imaged-guided percutaneous biopsy.
Recently, an automated biopsy gun has been introduced. Using this device and 18 Gauge Tru-cut needle, 100 biopsies of variable anatomic sites were performed with ultrasonic and computed tomographic guidance, 55 & 45 patients respectively.
The positive diagnostic rate of the biopsies was 88% : Diagnostic tissue was obtained in 80 of the 100 biopsies, and suggestive tissue was obtained in eight.
No case of the significant complication occurred, except only one case of minimal pneumothorax with spontaneous resolution.
Imaged-guided percutaneous biopsy using the automated biopsy gun could reduced the patient's discomfort and total procedure time compared with the conventional aspiration biopsies.
Based on the above results, imaged-guided percutaneous biopsy using the automated biopsy gun is a simple, safe and accurate method of obtaining adiquate specimen for the histopathologic diagnosis.
