背景和目的:支气管内超声(EBUS)和电磁导航支气管镜检查(ENB)提高了支气管镜诊断肺外周病变的诊断率,但联合应用上述技术能否克服各自的局限性,进一步提高诊断率,尚未得到临床验证。该研究是一项前瞻性随机对照试验,设3个诊断组:单独 EBUS 组、单独 ENB 组、EBUS 和ENB 联合组。全部操作均通过可弯曲支气管镜进行,经支气管活检钳活检没有使用荧光透视导引。联合诊断组进行电 BACKGROUND & OBJECTIVE: Endobronchial ultrasound (EBUS) and electromagnetic navigation bronchoscopy (ENB) improve the diagnostic rate of bronchoscopy in the diagnosis of peripheral lung disease. However, the combined use of the above techniques can overcome their respective limitations and further improve the diagnostic rate. Get clinical validation. This is a prospective randomized controlled trial of three diagnostic groups: EBUS alone, ENB alone, EBUS and ENB combined. All operations were performed with a flexible bronchoscope, and fluoroscopic guidance was not used for the biopsy of the bronchial biopsy forceps. Joint diagnostic group for electricity
