Utility of preoperative systemic inflammatory biomarkers in predicting postoperative complications after pancreaticoduodenectomy: Literature review and single center experience

Table 3 Statistical significance of preoperative inflammatory biomarkers

	Overall complications	Abdominal collection	PPH
NLR > 1.65	Ns	Ns	P = 0.016
dNLR > 1.47	Ns	P = 0.021
CRP > 881 mg/L	P = 0.0037	P = 0.016	Ns

CRP: C-reactive protein; dNLR: Derived neutrophil-to-lymphocyte ratio; NLR: Neutrophil-to-lymphocyte ratio; Ns: Not significant; PPH: Postoperative hemorrhage.
