Background/purpose: The aim in the present study was to elucidate the diagnostic ability of presepsin for postoperative infectious complications following major hepato-biliary-pancreatic (HBP) surgery.
Methods: Between 2017 and 2019, 50 patients with major hepatectomy and 55 patients with pancreatoduodenectomy were enrolled. Presepsin, the neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP), and procalcitonin (PCT) were prospectively measured for the first 2 weeks after surgery. The diagnostic abilities of these biomarkers were compared multidirectionally.
Results: All biomarkers returned to normal ranges within 2 weeks after surgery. However, presepsin, unlike the other biomarkers, showed less nonspecific elevation in response to the invasiveness of the surgical procedure immediately after surgery. Receiver operating characteristic curve analysis revealed that presepsin (area under the curve (AUC), 0.959) had a greater ability to discriminate bacterial infection than PCT (AUC, 0.723), CRP (AUC, 0.800), and the NLR (AUC, 0.804). A very high sensitivity of 93.3% and a specificity of 89.2% were achieved at the cutoff value of 620 pg/mL. Multivariable analysis revealed that presepsin on day 3 (P = .013) independently predicted bacterial infection after HBP surgery.
Conclusions: Presepsin may have a better predictive ability than existing biomarkers for infection following major HBP surgery, which may help us achieve faster and more accurate detection of bacterial infections.
