Does an elevated preoperative neutrophil-to-lymphocyte ratio predict major perioperative complications in patients undergoing colorectal surgery?
A preoperative neutrophil-to-lymphocyte ratio ≥ 2.3 may serve as a simple, accessible biomarker to predict major surgical complications following colorectal resection.
