研究设计:

非随机对照试验 

Study design:

Non randomized control 

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.

3.预计生存期>6 个月,可配合 6 个月随访。

Inclusion criteria

1.Thin-section CT indicates peripheral solitary pulmonary nodules (diameter < 30mm), with negative results from conventional bronchoscopy (without navigation/ultrasound guidance);
2.The patient or their legal representative has signed the informed consent form;
3.The expected survival period is more than 6 months, and the patient can cooperate with the 6-month follow-up.

2.严重心律失常(如未控制的室性心动过速);
3.凝血功能障碍(INR>1.5 或血小板<50×10?/L)或活动性大咯血(24h 咯血量>100ml);
4.结节紧邻大血管(距离<5mm)或胸膜(距离<2mm),经多学科会诊评估活检风险极高;
5.合并严重感染、免疫缺陷或恶性肿瘤晚期。

Exclusion criteria:

1.Intolerance to intravenous anesthesia or bronchoscopic procedures (e.g., severe cardiopulmonary insufficiency);
2.severe arrhythmia (e.g., uncontrolled ventricular tachycardia);
3.Coagulation disorders (INR > 1.5 or platelets < 50×10?/L) or active massive hemoptysis (hemoptysis volume > 100 ml within 24 hours);
4.Nodules adjacent to large blood vessels (distance < 5 mm) or pleura (distance < 2 mm), with extremely high biopsy risk evaluated by multidisciplinary consultation (MDC);
5.Complicated with severe infection, immunodeficiency, or advanced malignant tumors.
