Application of a single needle type for all image-guided biopsies: results of 100 consecutive core biopsies in various organs using a novel tri-axial, end-cut needle
Abstract
Purpose:
To assess feasibility, results and complications in image-guided
biopsies using a single needle design in various organs.
Materials and methods:
100 consecutive percutaneous biopsies were performed in 54
females and 46 males aged 24--87 years (mean age/standard
deviation: 64.5 +/- 12 years) using a full-core end-cut
tri-axial full-automatic biopsy needle (18 gauge BioPince TM,
InterV-MDTech, Gainesville, Florida) under CT (n = 45) or
ultrasound (n = 55) guidance. In 63 biopsies a coaxial technique
was used.
Results:
Biopsies were obtained of liver (n = 32), lymph nodes (n = 17),
thyroid (n = 11), lung (n = 9), adrenal (n = 9), pelvis (n = 6),
chest wall/pleura (n = 6), mediastinum (n = 4), lytic bone
lesions (n = 2), retroperitoneum (n = 1), muscle (n = 1),
pancreas (n = 1), peritoneum (n = 1). Between 1 and 6 (mean/SD
2.83 +/- 0.92) needle passes were performed. In 77 cases a
malignant (40 metastases, 37 primary tumours) and in 23 a benign
lesion was diagnosed. Of the 23 benign lesions a specific
diagnosis was possible in 22. In one case necrosis and
haemorrhage was diagnosed. In this patient surgery and autopsy
both revealed a mediastinal haematoma of unknown origin. Eight
minor complications (mild pain/local haematoma requiring no
therapy) and three major complications (three pneumothoraces in
nine lung biopsies requiring two aspirations and one drainage)
were observed. There was no mortality.
Conclusion:
Percutaneous image-guided biopsy using the described full-core
end-cut needle resulted in a specific diagnosis in 99/100
consecutive biopsies in various organs with a low complication
rate. We use this needle type for all CT- or US-guided biopsies
in all organs except for solid bone.
