机器人支气管镜在周围型肺结节活检中的临床应用

Clinical Application of Robotic Assisted Bronchoscopy in Peripheral Pulmonary Nodule Biopsy

随着胸部电子计算机断层扫描(computed tomography,CT)肺癌筛查的普及,周围型肺结节的检出率日益提高。部分患者通过获取活检标本明确诊断并及早治疗。经支气管肺活检是周围型肺结节非手术活检的方式之一,相较于经皮肺穿刺活检创伤小、并发症发生率低。然而,经支气管肺活检的诊断率约为70%,与经皮肺穿刺活检约90%的诊断率相比仍显逊色。2018年以来,机器人辅助支气管镜系统相继应用于临床,本文对其进一步提高周围型肺结节经支气管肺活检的诊断率加以综述。

With the popularization of chest computed tomography(CT)lung cancer screening,the detection rate of peripheral pulmonary nodules is increasing day by day.Some patients could make clear diagnoses and receive early treatment by obtaining biopsy specimens.Transbronchial lung biopsy(TBLB)is one of the non-surgical biopsy methods for peripheral pulmonary nodules,which has less trauma and lower incidence of complications compared to percutaneous thoracic needle biopsy(PTNB).However,the diagnostic rate of TBLB is about 70%,which is still inferior to that of PTNB,which is about 90%.Since 2018,robot assisted bronchoscopy systems have been applied in clinical practice.This article reviews their application in further improving the diagnostic rate of peripheral pulmonary nodules by TBLB.
