Estimation of pancreatic histology and likelihood of postoperative pancreatic fistula using extracellular volume fraction from contrast-enhanced computed tomography

Figure 5 Comparison between non-postoperative pancreatic fistula group and postoperative pancreatic fistula group in the imaging and histopathological findings. A: Main pancreatic duct diameter (4 mm vs 2 mm; P < 0.001); B: Computed tomography value in equilibrium phase (110.5 HU vs 94.3 HU; P = 0.001); C: Extracellular volume fraction (37.2% vs 30.5%; P = 0.003); D: Area of acini (0.802 mm²vs 0.880 mm²; P = 0.127); E: Area of fibrosis (0.041 mm² vs 0.026 mm²; P = 0.110). ^aP < 0.001; ^bP < 0.01. POPF: Postoperative pancreatic fistula; MPD: Main pancreatic duct; CT: Computed tomography; ECVf: Extracellular volume fraction.
