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

摘要

BACKGROUND The role of preoperative inflammatory biomarkers(PIBs)in predicting postoperative morbidity has been assessed in colorectal and otorhinolaryngeal surgery.However,data regarding the role that preoperative inflammatory biomarkers have on morbidity after pancreaticoduodenectomiy(PD)are less consistent.AIM To assess the utility of PIBs in predicting postoperative complications after pancreaticoduodenectomy.METHODS A database of 317 consecutive pancreaticoduodenectomies performed from April 2003 to November 2018 has been retrospectively analyzed.Data regarding preoperative neutrophil-to-lymphocyte ratio(NLR),derived NLR and C-reactive protein(CRP),and postoperative complications of 238 cases have been evaluated.Exclusion criteria were:age8.81 mg/dL were at higher risk of both overall complications and abdominal collections(respectively P=0.0037,PPV=0.95,negative predictive value[NPV]=0.27 and P=0.016,PPV=0.59,NPV=0.68).Preoperative derived neutrophil-to-lymphocyte ratio(dNLR)(cut off>1.47)was also a predictor of abdominal collection(P=0.021,PPV=0.48,NPV=0.71).Combining CRP and dNLR,PPV increased to 0.67.NLR(cut off>1.65)was significantly associated with postoperative hemorrhage(P=0.016,PPV=0.17,NPV=0.98).CONCLUSION PIBs may predict complications after PD.During postoperative care,PIB levels could influence decisions regarding the timing of drains removal and the selection of patients who might benefit from second level diagnostic exams.
