【摘要】目的：探讨超声小探头引导下经支气管镜活检在周围型肺部病变中的应用效果，为其临床应用提供理论依据。方法：选取74例接受超声小探头引导下支气管镜活检的周围型肺部病变的患者。分析患者的最终诊断结果；分析超声小探头引导下经支气管镜活检诊断周围型肺部病变的诊断准确性；分析病变大小、位置对诊断准确性的影响；分析周围型肺部病变的超声表现及超声探头位置对诊断准确性的影响。结果：周围型肺部病变中，%，其次为肺炎，%。肺癌患者以腺癌（%）最常见，其次为非小细胞癌（%）。%。66例（%）患者经超声小探头准确识别和定位。%，显著低于良性病变的诊断成功率（P＜）；%，%，两者对比，差异没有统计学意义（P＞）。病灶直径＞%，显著高于病灶直径
≤20mm的诊断成功率（P＜）；肺部中/%，显著高于肺部上叶病灶的诊断成功率（P＜）。%，显著高于超声小探头偏离病灶的诊断成功率（P＜）。结论：超声小探头引导下经支气管镜活检诊断周围型肺部病变的成功率较高，安全性良好。病灶大小和位置、探头与病灶的位置关系等因素可对诊断成功率产生影响。

Application of transbronchoscopic biopsy guided by small ultrasonic probe in peripheral lesions
[Abstract] Objective: To explore the application effect of transbronchoscopic biopsy guided by small ultrasonic probe in peripheral pulmonary lesions, and to provide theoretical basis for its clinical application. Methods: 74 patients with peripheral pulmonary lesions were selected for bronchoscopy biopsy under the guidance of small ultrasonic probe. To analyze the final diagnosis results of patients; to analyze the accuracy of diagnosis of peripheral pulmonary diseases by bronchoscopy biopsy under the guidance of small ultrasonic probe; to analyze the
