Image-Guided Percutaneous Biopsies with a Biopsy Gun
Abstract
- PURPOSE
We report the results of image-guided percutaneous biopsies with a biopsy gun and evaluate the
clinical usefullness.
MATERIALS AND METHODS
One hundred and five biopsies under ultrasonographic or fiuoroscopic guidance
were performed. Various anatomic sites were targeted (liver;50, chest;22, kidney;12, pancreas;8, intraperitoneum;7,
retroperitoneum; ).
RESULTS
Obtained tissue was diagnostic in 98 of the 105 biopsies(93%). In each instance, representative
core tissue specimens were obtained. Evaluation of the core tissue by pathologist revealed consistent, uniform
specimens that contained significant crush artifact in no case. Five biopsies yielded inadeguate tissues which
were too small for histopathologic interpretation or were composed of necrotic debris. Two biopsies yielded
adequate tissues, but tissues were not of the target. The diagnoses were malignancy in 77 biopsies and benign
disease in 21 biopsies. No complications other than mild, localized discomfort were encountered except a
transient hemoptysis and pneumothorax which was observed in two patients.
CONCLUSION
Cutting biopsy with a biopsy gun provided sufficient amount of target tissue for an accurate
diagnosis of malignant and benign disease. It was a safe and useful procedure for percutaneous biopsy.
