Background and objective: By analyzing morpholoy and edge of endobronchial ultrasound (EBUS) images in 47 patients with pulmonary malignant lesions. The aim of this study is to explore the role of EBUS in the diagnosis of pulmonary malignant lesions.
Methods: From June 1, 2005 to June 30, 2006, EBUS analysis was performed in a proportion of patients with malignant or benign lesions.
Results: In total 78 patients of confirmed diagnosis, 47 cases were confirmed malignant lesions, and 31 were benign lesions, male 56 cases, female 22 cases, age span from 21-80 years (58.01 +/- 13.20). The statistics of the lesion edge imaging in 78 patients showed that different position and angle did not affect the morphous of the edge; analysis of the relationship between the size of the lesion and the morphous of the edge shows that the size of the lesion does not affect the morphous of the edge; the comparison between lesions of benign and malignant shows that a clear edge is the major feature of malignant lesions, indicating certain value in diagnosis; comparison between the shape of the lesion and the property of the lesion shows no relationship between them; compared to conventional bronchoscopy operations, the EBUS operation consumes approximately 10 min, and no related complication was found.
Conclusion: Clear morphous of the edge in EBUS is a feature of the malignant lesion, and EBUS has certain value in the diagnosis of the malignant lesions.
背景与目的: 本研究旨在通过分析支气管内超声（endobronchial ultrasound, EBUS）边缘形态的图像，探索EBUS图像的边缘形态对恶性肺部病变的诊断作用。
方法: 收集从2005年6月1日-2006年6月30日期间就诊的部分良恶性病例进行EBUS图像分析。
结果: 共确诊了47例恶性病变，另外还确诊了31例良性病变，共78例病灶良恶性诊断明确者，男56例，女22例，年龄21岁-80岁，平均（58.01±13.20）岁；78例患者的病灶部位和病变的边缘统计结果显示，不同部位和角度对超声的边缘形态没有影响；病灶的大小和病灶的边缘形态的关系分析显示病灶的大小与病灶的边缘形态无影响；恶性病变与良性病变边缘形态的比较显示，边缘清晰是恶性病变的重要表现，同时显示一定的诊断价值；根据病灶的外形与病变的性质比较，未发现超声图像的外形与病变性质的相关关系；与正常的支气管镜操作相比，EBUS的操作约进行10 min左右，未发现有关的并发症。
结论: EBUS图像边缘清晰是恶性病变的一个特征，对恶性病变有一定的诊断价值。
