"The following groups of biomarkers will be examined:~* standard panel of inflammation markers: CRP, PCT, IL-6, Leukocyte count, differential blood count~* microbiology cultures according to the clinical status~* serum biomarkers: sCD64, sTREM-1, calprotectin, pentraxin 3~* flow cytometry: HLA-DR, CD14, CD16, CD40, CD45, CD64, CD163 expression on granulocytes and monocytes~* cell function assay: IL-18 and IFN-γ~* hematology: ICIS, Neutrophil-to-lymphocyte ratio - examined together with conventional hematological parameters.~The schedule of blood sample taking will be as follows:~A. the study group: preoperatively (T-1), 1st postoperative day (T1), 3rd postoperative day (T2), 7th postoperative day (T3), 10th postoperative day (T4)~B. the control group: at admission or the next day (T1), 3rd day of hospital stay (T2), 7th day of hospital stay (T3), 10th day of hospital stay (T4)"
