title: Blunt-tip coaxial introducer: a revisited tool for difficult CT-guided biopsy in the chest and abdomen.
abstract: OBJECTIVE
  We describe a coaxial introducer provided with an additional blunt-tip stylet that allows safe access to difficult-to-reach lymph nodes in the chest, abdomen, and pelvis under CT control.
  
  
  CONCLUSIONS
  Once the thoracic, abdominal, or pelvic wall is crossed by the introducer fitted with the sharp-tip stylet, the blunt-tip stylet replaces the sharp stylet for further progression in the fat toward the target. The soft-tip stylet carries a smaller risk of inadvertent perforation displacing vital structures.
