Table_1_v1_Clinical comparison of three-dimensional exoscope vs. operative microscope in transforaminal lumbar interbody fusion: A retrospective case-control study.xls

PurposeHere, we sought to determine the safety and feasibility of three-dimensional exoscope (3D EX). We compared data on surgery, complications, postoperative drainage, hematology, and clinical outcomes in the group that underwent transforaminal lumbar interbody fusion (TLIF) using an operative microscope (OM) relative to those treated using 3D EX.MethodsWe retrospectively reviewed records on 74 patients who underwent one- or two-level TLIF from August 2019 to October 2020. Repeated measures analysis of variance was used to compare pre- and post-operative visual analogue scale (VAS) scores and oswestry disability index (ODI). We used analysis of covariance to compare pre- and post-operative erythrocyte count (RBC), hemoglobin (Hb), and hematocrit (Hct). Independent sample t-tests was used to compare postoperative drainage volume, total blood loss (TBL), visible blood loss (VBL) and hidden blood loss (HBL).ResultsThere were no significant differences in VAS and ODI scores between the two groups at all time points (all p > 0.05). RBC and HBL did not differ significantly between the two groups (all p > 0.05). There were significant differences in postoperative drainage volume,TBL, Hb, and Hct values when using 3D EX relative to OM in two-level TLIF (all p  0.05). The two groups differed significantly with regards to VBL when used for one- or two-level TLIF (all p

在此研究中，我们旨在探讨三维腹腔镜（3D EX）的安全性及可行性。我们对比分析了采用手术显微镜（OM）与3D EX治疗的经椎间孔腰椎椎体融合术（TLIF）患者在手术、并发症、术后引流、血液学指标及临床疗效方面的数据。方法上，我们对2019年8月至2020年10月期间接受一或两节段TLIF的74名患者进行了回顾性病历审查。通过重复测量方差分析比较了术前和术后的视觉模拟评分（VAS）和奥斯维斯特里功能障碍指数（ODI）。采用协方差分析比较了术前和术后的红细胞计数（RBC）、血红蛋白（Hb）和血细胞比容（Hct）。独立样本t检验用于比较术后引流量、总失血量（TBL）、明显失血量（VBL）和隐匿失血量（HBL）。结果显示，两组患者在所有时间点VAS和ODI评分之间均无显著差异（所有p>0.05）。两组患者的RBC和HBL无显著差异（所有p>0.05）。在两节段TLIF中，使用3D EX相对于OM，术后引流量、TBL、Hb和Hct值存在显著差异（所有p<0.05）。在用于一或两节段TLIF时，两组患者的VBL存在显著差异（所有p<0.05）。
