Core Tip

Core tip: This is a retrospective study to demonstrate the usefulness of the neutrophil-lymphocyte ratio in predicting the manifestation of severe acute pancreatitis and organ failure in the early stages in patients with acute pancreatitis. The neutrophil-lymphocyte ratio is cost-effective and easy to use, utilizing tests already routinely performed. This study found the neutrophil-lymphocyte ratio to be a reliable predictor of adverse outcomes in patients with acute pancreatitis and established the optimal cut-off value of the neutrophil-lymphocyte ratio for predicting these outcomes.
