Preoperative platelet-to-lymphocyte ratio and post-hepatectomy hemorrhage risk after elective hepatectomy: a single-center cohort study with exploratory calendar-time assessment of a candidate cutoff

Post-hepatectomy hemorrhage (PHH) is clinically important after liver resection, yet simple preoperative bleeding risk markers remain limited. We assessed whether preoperative platelet-to-lymphocyte ratio (PLR) was associated with PHH and derived an ROC-based threshold. In this a...
