During routine endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) procedures, especially with biopsy of lymph nodes in or around the left upper lobe, frequent reports have noted the loss of ultrasound image and needle angulation leading to an inability to biopsy nodes visualised by EBUS. The aim of this research was to investigate and compare this loss of angulation with commercially available scopes. Bench-top experiments and a clinical case study demonstrated the varying loss of scope angulation, flexibility and manoeuvrability with different scopes and biopsy instruments leading to procedural implications. Improvements in both the EBUS scope and needle characteristics are required to overcome this limitation which has implications in bronchoscope navigation and the diagnostic yield of EBUS-TBNA.
在常规的支气管内超声引导下经支气管针吸活检（EBUS-TBNA）操作过程中，尤其是对左上叶内或其周围淋巴结进行活检时，常有报告指出超声图像和针角度丢失，导致无法对EBUS显示的淋巴结进行活检。本研究的目的是调查和比较不同商用支气管镜这种角度丢失情况。台式实验和临床病例研究表明，不同的支气管镜和活检器械在角度、灵活性和可操作性方面存在不同程度的丢失，从而产生操作上的影响。需要改进EBUS支气管镜和针的特性，以克服这一限制，这对支气管镜导航和EBUS-TBNA的诊断率都有影响。
