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 0.92 ± 0.78 1.32 ± 0.78 0.030
Retention of appropriate architecture 0.97 ± 0.75 1.42 ± 0.72 0.010
Degree of cellular degeneration 1.37 ± 0.75 1.61 ± 0.60 0.132
Degree of cellular trauma 1.26 ± 0.72 1.47 ± 0.60 0.173
Background blood or clot 1.11 ± 0.69 1.24 ± 0.71 0.416
Total score 5.63 ± 3.32 7.05 ± 3.00 0.054
  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
