2015年5月23日 · Chapter 16 EBUS-TBNA of Right Lower Paratracheal Lymph Node (Station 4R) This chapter emphasizes the following elements of the Four Box Approach: patient’s significant comorbidities; patient preferences and expectations (also includes family); risk-benefit analyses and therapeutic alternatives; techniques and instrumentation; and follow-up ...

By withdrawing the endoscope just beyond the main carina and by turning it to the 3 o’clock position, lymph node station 4R (Lower paratracheal nodes) can be found. LN4R is close to the vena cava and azygos vein.

2015年6月15日 · 在过去的 40 年间，多种淋巴结分布情况通过采用解剖学分布（如右下支气管旁）或数量（如 4R）对胸内淋巴结进行标记来明确肺癌患者是否存在临床和病理性淋巴结受累。 这些淋巴结受累的评估标准包括来自 Naruke、美国胸科学会（ATS）、Mountain Dressler-ATS (MD-ATS) 所制定的标准，以及改良 ATS 标准。 Naruke 分布被日本的外科医生和肿瘤科医生广泛采纳，而 MD-ATS 则在北美地区应用更广。 国际肺癌研究协会（IASLC）提出了 TNM 分期的改 …

Currently, EBUS-TBNA/EUS-FNA is the preferred modality for sampling mediastinal lymph nodes because of its minimally invasive nature and high diagnostic yield. In this review, we discuss the utility of endosonographic procedures in mediastinal lymph node staging of NSCLC.

2019年2月13日 · Surgical staging by mediastinoscopy has been considered the gold standard for staging of the mediastinum in non–small cell lung cancer for many years; however, more recently, minimally invasive endosonographic procedures using combined endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS) have replaced mediastinoscopy as the method ...

2014年4月23日 · Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a minimally invasive technique for evaluating the mediastinum and staging patients with lung cancer. In the hands of an experienced operator, the procedure is safe and provides excellent sensitivity, specificity, and predictive diagnostic values.

2010年5月7日 · eus（2r、4r、4l、7区和左肾上腺）比ebus多发现12枚恶性淋巴结。 提示EBUS是获取气管前、10区和11区淋巴结的唯一方式；反之，EUS是获取8区（2例）、9区（1例）和肾上腺区域淋巴结的唯一方式。

2012年10月23日 · Planning EBUS-TBNA of right lower paratracheal lymph node (station 4R). Define the borders of station 4R and justify this definition. Describe how sagittal view of a computed tomography scan is used to plan EBUS-TBNA at station 4R.

2015年5月23日 · Station 4R sampling should be accompanied by a complete sonographic mediastinal and hilar nodal assessment because the tumor may be upstaged to N3 (stage IIIB), in case EBUS identifies contralateral lymph nodes from which aspirates are positive for malignancy. 20 The lymph nodes would be systematically visualized by starting with N1 lymph nodes ...
