Sensitivity and Specificity of the Platelet-Lymphocyte Ratio and the Neutrophil-Lymphocyte Ratio in Diagnosing Acute Mesenteric Ischemia in Patients Operated on for the Diagnosis of Mesenteric Ischemia: A Retrospective Case-Control Study.

ABSTRACT

Aim: The present study aims to determine whether various hematological parameters and ratios of patients could be used to diagnose AMI. Materials and Methods: The subjects of the study are the patients who were hospitalized with an acute mesenteric ischemia (AMI) pre-diagnosis and underwent surgery as a consequence. The patients who were determined to have the diagnosis of AMI intraoperatively are categorized in the AMI Group. The patients whose operations do not reveal AMI (negative exploration) are categorized in the Control Group. These two groups are compared in terms of hematological parameters and rates. Results: In the study, the PLR (p = 0.017), NLR (p = 0.33), PDW (0.023), RDW (p = 0.025) values are significantly higher in the AMI group compared to the control group while the LYMP (p = 0.023) count is significantly lower. Conclusions: For the patients admitted to the emergency clinics with suspected AMI, the increased PLR, NLR, PDW, and RDW values together with the reduced lymphocyte count can be used to support the diagnosis.
