Endobronchial ultrasonography using a guide sheath (EBUS-GS) is a novel method used for collecting peripheral pulmonary lesion (PPL) samples. EBUS-GS is performed by introducing a guide sheath-covered miniprobe into the target bronchus and then withdrawing the miniprobe after lesion detection, leaving the guide sheath in situ as a working channel for obtaining lesion samples. EBUS-GS can improve PPL diagnosis rates and be used for obtaining specimens for molecular analysis. In this review, we discuss the clinical applications of EBUS-GS, the factors that affect its diagnostic sensitivity, and potential complications. We also compare EBUS-GS with other available diagnostic techniques and discuss the strengths and limitations of this method.
使用引导鞘的支气管内超声检查(EBUS-GS)是一种用于采集周围型肺病变(PPL)样本的新方法。EBUS-GS的操作是将一个覆盖引导鞘的微型探头插入目标支气管,在检测到病变后撤回微型探头,将引导鞘留在原位作为获取病变样本的工作通道。EBUS-GS可以提高PPL的诊断率,并用于获取分子分析的标本。在本综述中,我们讨论了EBUS-GS的临床应用、影响其诊断敏感性的因素以及潜在并发症。我们还将EBUS-GS与其他可用的诊断技术进行比较,并讨论该方法的优缺点。
