研究目的: |
遵循 PICO 原则,明确: 目标人群(P):经薄层 CT 导航联合 R-EBUS 检查的肺外周孤立性结节(直径<30mm)患者; 干预措施(I):径向超声引导下超细支气管镜 + 测距法 + 1.1mm 冷冻探针活检(1-3 次取材); 对照措施(C):径向超声引导下导向鞘 + 钳夹活检(8 次取材); 临床结局(O):主要结局为两组诊断率(明确病理诊断例数 / 总例数),次要结局为并发症发生率(出血、气胸)、操作时间、标本量满足后续检测比例。 最终目标:验证冷冻活检诊断率非劣效于钳夹活检,且并发症无显著增加,为 SPNs 诊断提供更优技术选择。 |
||||||||||||||||||||||
|
Objectives of Study: |
In accordance with the PICO principle, specify the following: Population (P): Patients with small peripheral pulmonary nodules (SPNs, diameter < 30mm) undergoing thin-section CT-guided combined radial endobronchial ultrasound (R-EBUS) examination. Intervention (I): Radial ultrasound-guided ultra-thin bronchoscope + distance measurement + 1.1mm cryoprobe biopsy (3 sampling attempts). Comparison (C): Radial ultrasound-guided guide sheath + forceps biopsy (8 sampling attempts). Outcomes (O): Primary outcome: Diagnostic rate in both groups (number of cases with definite pathological diagnosis / total number of cases). Secondary outcomes: Incidence of complications (bleeding, pneumothorax), procedure time, and proportion of specimens sufficient for subsequent testing. Ultimate Objective: Verify that the diagnostic rate of cryobiopsy is non-inferior to that of forceps biopsy, with no significant increase in complications, thereby providing a more optimal technical option for the diagnosis of SPNs. |
