摘　　要：经支气管腔内超声（endobronchial ultrasonograghy，EBUS）是将微型超声探头经支气管镜的操作通道送入气管-支气管腔，通过对病变部位的超声扫描，获得管壁、管周结构的超声图像，从而提高诊断效率的方法。研究表明EBUS有助于鉴别管壁内病变的良恶性，可以准确判断早期中央性肺癌的侵犯深度以指导支气管内治疗，显著提高肺癌N、T分期的准确性，并改善支气管镜对纵隔、肺周边良恶性病变的诊断效率，是一项值得推广的检查手段.Endobronchial ultrasonograghy（EBUS） can get the ultrasonic imaging of endoluminal, intramural and extraluminal lesions by introducing ultrasound micro-probe into bronchus through the working channel of bronchoscope. The evaluation of depth of early central lung cancer would be more accurate through EBUS. EBU,S-guided transbronchial needle aspiration improved the results of N-staging of lung cancer,especially in difficult lumph node levels without any clear endoscopic landmarks, EBUS is also useful for biopsying peripheral lesions or solitary pulmonary nodules instead of fluoroscopic guidance.
