Core Tip	This retrospective study of 146 patients explored hidden blood loss (HBL) during dual-media spinal endoscopy (DME) for lumbar spinal stenosis. HBL was calculated using Nadler’s formula and hematocrit (Hct) changes, and risk factors were analyzed by correlation and regression methods. HBL accounted for the majority of total blood loss (TBL) in DME. Operating time, TBL, preoperative Hct and hemoglobin were independent risk factors for HBL. Activated partial thromboplastin time and fibrinogen were also correlated with HBL. Clarifying these factors aids perioperative blood management.
