Application of Coaxial Core Biopsy Needle in CT Guided Percutaneous Abdominal Biopsy

Objective:To evaluate the clinical application of coaxial core biopsy needle in CT-guided percutaneous abdominal biopsy.(Methods:)CT-guided coaxial core needle biopsy was performed in 41 lesions in 40 patients of abdominal(diseases.)The lesions located in liver(n=13),retroperitoneum(n=24),abdominal cavity(n=2),pelvis(n=2).The sizes of the lesions ranged from 1.0cm×1.0cm to 10.1cm×12.3cm.Results:Successful biopsies were achieved in all 41 lesions.Cytological and pathological examinations were performed in 41 and 40 lesions respectively.As compared with the results of surgery and clinical followup,the diagnostic accuracy of pathological examinations was 92%(23/25) for malignant lesions,86.7%(13/15) for benign lesions,with a total accuracy of 90.0%(36/40).No severe complications were happened in all patients.Conclusion:CT-guided percutaneous biopsy with coaxial core biopsy needle is a simple,safe and accurate method for diagnosis of abdominal diseases.
