Histological evaluation of the pancreatic stump to estimate the percentage of a parenchymal and interlobular (PI) area using ImageJ software. a. Loupe images of the pancreatic stump with hematoxylin and eosin staining and their binary images by ImageJ software. After the outer circumference of the entire cut surface (red line) is manually outlined, the entire cut surface area is measured by using ImageJ software. The black area is regarded as the PI area. The white area is regarded as the area including fatty tissue. Magnified pictures showed representative images according to the POPF low or high-risk groups in the soft pancreas. In a typical case with POPF low risk (upper picture of A), the percentage of PI area/entire surface area was 80.0% (252.1 / 315.8 × 100). On the other hand, in a typical case with POPF high risk (lower picture of A), the percentage of PI area/entire surface area was 52.6% (132.6 / 252.1 × 100). b. Box plot graph for the comparison of the percentage of PI area. It is significantly higher than in the POPF low-risk group than that of the high-risk group (p = 0.00002)
