: Oblique Lateral Interbody Fusion (OLIF) is a widely performed, minimally invasive technique to achieve lumbar lateral interbody fusion. However, some complications can arise due to constraints posed by the limited surgical space and visual field. The purpose of this study was to assess the short-term postoperative clinical outcomes of microendoscopy-assisted OLIF (ME-OLIF) compared to conventional OLIF. : We retrospectively investigated 75 consecutive patients who underwent OLIF or ME-OLIF. The age, sex, diagnosis, and number of fused levels were obtained from medical records. Operation time, estimated blood loss (EBL), and intraoperative complications were also collected. Operation time and EBL were only measured per level required for the lateral procedure, excluding the posterior fixation surgery. The primary outcome measure was assessed using the Japanese Orthopedic Association Back Pain Evaluation Questionnaire (JOABPEQ). The secondary outcome measure was assessed using the Oswestry Disability Index (ODI) and the European Quality of Life-5 Dimensions (EQ-5D), measured preoperatively and 1-year postoperatively. : This case series consisted of 14 patients in the OLIF group and 61 patients in the ME-OLIF group. There was no significant difference between the two groups in terms of the mean operative time and EBL ( = 0.90 and = 0.50, respectively). The perioperative complication rate was 21.4% in the OLIF group and 21.3% in the ME-OLIF group ( = 0.99). In both groups, the postoperative JOABPEQ, EQ-5D, and ODI scores improved significantly ( < 0.001). : Although there was no significant difference in clinical results between the two surgical methods, the results suggest that both are safe surgical methods and that microendoscopy-assisted OLIF could serve as a potential alternative to the conventional OLIF procedure.
: 斜外侧腰椎间融合术（OLIF）是一种广泛应用的微创技术，用于实现腰椎侧方椎间融合。然而，由于手术空间和视野的限制，可能会出现一些并发症。本研究旨在评估与传统 OLIF 相比，微创辅助 OLIF（ME-OLIF）的短期术后临床结果。 : 我们回顾性调查了 75 例连续接受 OLIF 或 ME-OLIF 治疗的患者。从病历中获得了年龄、性别、诊断和融合节段数。还收集了手术时间、估计失血量（EBL）和术中并发症。手术时间和 EBL 仅按侧方手术所需的节段测量，不包括后路固定手术。主要观察指标采用日本矫形协会腰痛评估问卷（JOABPEQ）评估。次要观察指标采用 Oswestry 残疾指数（ODI）和欧洲生活质量 5 维问卷（EQ-5D）评估，术前和术后 1 年进行评估。 : 本病例系列包括 OLIF 组 14 例和 ME-OLIF 组 61 例。两组间平均手术时间和 EBL 无显著差异（=0.90 和=0.50）。OLIF 组围手术期并发症发生率为 21.4%，ME-OLIF 组为 21.3%（=0.99）。两组术后 JOABPEQ、EQ-5D 和 ODI 评分均显著改善（<0.001）。 : 虽然两种手术方法的临床结果无显著差异，但结果表明两种方法均安全，微创辅助 OLIF 可能是传统 OLIF 术式的一种潜在替代方法。
