From: Endoscopic ultrasound-guided sampling of solid pancreatic masses: 22-gauge aspiration versus 25-gauge biopsy needles

  22-gauge FNA (n = 38) 25-gauge FNB (n = 38) P value
Amount of cellular material 1.26 ± 0.72 1.55 ± 0.72 0.085
Retention of appropriate architecture 1.39 ± 0.68 1.63 ± 0.67 0.132
Degree of cellular degeneration 1.42 ± 0.60 1.58 ± 0.64 0.271
Degree of cellular trauma 1.26 ± 0.55 1.53 ± 0.65 0.061
Background blood or clot 1.29 ± 0.70 1.53 ± 0.73 0.150
Total score 6.63 ± 2.90 7.82 ± 3.14 0.092
  1. FNA fine needle aspiration, FNB fine needle biopsy
  2. Continuous variables are expressed as the mean ± standard deviation
  3. a The scoring system reported by Mair et al. [19] was used for the assessment of sample quality
