Unilateral biportal endoscopic (UBE) spine surgery is a minimally invasive procedure for treating lumbar disorders. Hidden blood loss (HBL) is easily ignored by surgeons because blood loss is less visible. However, there are limited studies on HBL in UBE spine surgery. This study aimed to evaluate HBL and its possible risk factors in patients undergoing UBE spine surgery.
Patients with lumbar disc herniation or lumbar spinal stenosis who underwent unilateral biportal endoscopic surgery between December 2020 and February 2022 at our hospital were retrospectively analyzed. Patient demographics, blood loss-related parameters, and surgical and radiological information were also collected. Pearson or Spearman correlation analysis was conducted to determine the association between clinical characteristics and HBL. Multivariate linear regression analysis was used to determine the independent risk factors for HBL.
Fifty-two patients (17 males and 35 females) were retrospectively enrolled in this study. The mean total blood loss (TBL) volume was 434 ± 212 ml, and the mean HBL volume was 361 ± 217 ml, accounting for 77.9% of the TBL in patients who underwent UBE surgery. Multivariate linear regression analysis revealed that HBL was positively associated with operation time ( = 0.040) and paraspinal muscle thickness at the target level ( = 0.033).
The amount of HBL in patients undergoing UBE surgery should not be neglected. Operation time and paraspinal muscle thickness at the target level may be independent risk factors for HBL.
单侧双通道内镜（UBE）脊柱手术是治疗腰椎疾病的一种微创手术。隐匿性失血（HBL）容易被外科医生忽视，因为失血不太明显。然而，关于UBE脊柱手术中HBL的研究有限。本研究旨在评估接受UBE脊柱手术患者的HBL及其可能的危险因素。
回顾性分析2020年12月至2022年2月在我院接受单侧双通道内镜手术的腰椎间盘突出症或腰椎管狭窄症患者。还收集了患者的人口统计学资料、失血相关参数以及手术和影像学信息。采用Pearson或Spearman相关性分析来确定临床特征与HBL之间的关联。采用多元线性回归分析来确定HBL的独立危险因素。
本研究共回顾性纳入52例患者（17例男性，35例女性）。平均总失血量（TBL）为434±212ml，平均HBL量为361±217ml，占接受UBE手术患者TBL的77.9%。多元线性回归分析显示，HBL与手术时间（=0.040）和目标节段椎旁肌厚度（=0.033）呈正相关。
接受UBE手术患者的HBL量不应被忽视。手术时间和目标节段椎旁肌厚度可能是HBL的独立危险因素。
