Study design:

Cohort study 

研究目的:

1.分析腰椎管狭窄症患者行单侧双通道内镜腰椎减压术后功能改善较慢的相关因素,筛选独立危险因素,并构建风险预测模型。 2.以术后3个月 ODI 是否达到最小临床重要差异值为结局指标,评估临床及影像学参数对术后恢复的预测价值。  

Objectives of Study:

1.To analyze the factors associated with slow functional improvement in patients with lumbar spinal stenosis after unilateral biportal endoscopic lumbar decompression, screen for independent risk factors, and establish a risk prediction model. 2.Using whether the Oswestry Disability Index (ODI) at 3 months postoperatively achieved the minimal clinically important difference (MCID) as the outcome measure, to evaluate the predictive value of clinical and radiological parameters for postoperative recovery.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.年龄≥18岁; 2.明确诊断为腰椎管狭窄症,且经规范保守治疗无效,仍存在手术指征; 3.术前磁共振成像(MRI)及计算机断层扫描(CT)检查结果与临床症状、体征相符; 4.接受单侧双通道内镜腰椎减压术(UBELD)治疗; 5.术后随访时间不少于3个月,且临床资料、影像学资料及随访资料完整。

Inclusion criteria

1.Age >=18 years; 2.Definitive diagnosis of lumbar spinal stenosis with failure of standardized conservative treatment and remaining surgical indications; 3.Preoperative magnetic resonance imaging (MRI) and computed tomography (CT) findings consistent with clinical symptoms and signs; 4.Undergoing unilateral bilateral endoscopic lumbar decompression surgery (UBELD); 5.Postoperative follow-up duration of no less than 3 months with complete clinical data, imaging data, and follow-up records.

排除标准:

1.存在峡部裂性脊柱滑脱Ⅲ度及以上、冠状位 Cobb 角≥20°或其他明显腰椎不稳者; 2.既往同节段行腰椎手术并需再次翻修者; 3.合并腰椎骨折、感染、肿瘤或强直性脊柱炎等其他严重脊柱疾病者; 4.合并阿尔茨海默病、帕金森病等神经退行性疾病者; 5.随访不足或临床资料不完整者。

Exclusion criteria:

1.Patients with grade III or higher pars interarticularis fissure-related spondylolisthesis, coronal Cobb angle ≥20°, or other significant lumbar instability; 2.Previous lumbar surgery at the same segment requiring revision; 3.Concurrent severe spinal conditions such as lumbar fractures, infections, tumors, or ankylosing spondylitis; 4.Associated neurodegenerative disorders including Alzheimer's disease or Parkinson's disease; 5.Inadequate follow-up or incomplete clinical data. According to the original study, during outcome evaluation, cases of structural failure due to recurrent stenosis or insufficient decompression, as well as those failing to meet minimal clinically important differences (MCID) due to preoperative overly low objective disability index (ODI), were excluded from the slow functional improvement assessment to minimize bias and enhance study population homogeneity.

数据采集和管理(说明:数据采集和管理由两部分组成,一为病例记录表(Case Record Form, CRF),二为电子采集和管理系统(Electronic Data Capture, EDC),如ResMan即为一种基于互联网的EDC:

本研究数据采集采用病例记录表(CRF)结合电子数据库管理的方式进行。首先依据研究方案设计统一的CRF表,由经过培训的研究人员从住院病历系统、手术记录、影像资料及随访记录中提取受试者资料,内容包括一般人口学信息、临床资料、影像学参数、围手术期资料及结局指标。采集完成后,由专人将数据录入电子数据管理系统(EDC)或Excel/R数据库,实行双人核对和逻辑校验,发现疑问后及时回溯原始资料进行修正。所有受试者资料均采用唯一编码进行去标识化管理,源数据、CRF表及电子数据库由专人保管,未经授权不得修改、复制或外传,以保证数据真实、完整、准确和可追溯。

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Data collection in this study was performed using a case report form (CRF) combined with electronic database management. First, the researchers developed a standardized CRF in accordance with the study protocol. Trained investigators extracted participant data from the inpatient medical record system, operative records, imaging documents and follow-up records, including general demographic information, clinical data, imaging parameters, perioperative data and outcome measures. After collection, dedicated personnel entered the data into an Electronic Data Capture (EDC) system or Excel/R database. Double data entry and logical verification were conducted; any discrepancies were resolved by tracing back to the original records for correction in a timely manner. All participant data were managed in a de-identified manner with unique coding. Source data, CRFs and electronic databases were kept by dedicated staff, and no unauthorized modification, duplication or external transmission was allowed, so as to ensure the authenticity, integrity, accuracy and traceability of all data.
