Changes in the blood test values of (a) WBC, (b) ALP, and (c) γ-GTP at the onset of post-PD cholangitis and after starting the initial treatment. Blood test results showed changes in the (a) white blood cell (WBC) counts, (b) alkaline phosphatase (ALP) levels, and (c) gamma-glutamyl transpeptidase (γ-GTP) values at the onset of post-pancreaticoduodenectomy cholangitis (PPDC) and after starting the initial treatment. For WBC counts, the median at the onset of PPDC and first blood test after starting treatment were 10,385 (range: 4120‒21,690) and 6000 (range: 2570‒17,260), respectively (a). The Wilcoxon signed-rank sum test for the two corresponding groups showed a statistically significant difference with P = 1.2 × 10^–6 (a). For ALP level, the median at the onset of PPDC and first blood test after starting treatment were 614 (range: 204‒2890) and 516 (range: 135‒2706), respectively (b). A statistically significant difference was noted among the two corresponding groups, with P = 3.2 × 10^–3 (b). For γ-GTP values, the median at the onset of PPDC and first blood test after starting treatment were 160 (range: 9‒1693) and 184 (range: 9‒1042), respectively (c). A statistically significant difference was noted among the two corresponding groups, with P = 0.016 (c)
