“…However, newer techniques, such as EBUS‐IFB and EBUS‐cryo as well as newer EBUS‐TBNA needles with fabricated needle tips for core tissue sampling and 19‐gauge EBUS‐TBNA needles, may create a firmer and larger tract than the standard 21‐gauge or 22‐gauge EBUS‐TBNA needle. 18 , 19 , 20 There are currently no TS reports with newer techniques or needles for EBUS‐TA. Although newer techniques and needles may be advantageous in tissue sampling, bronchoscopists should be aware of the possibility of tumor invasion through the tract created with EBUS‐TA.…”

Airway stenosis complicated by endobronchial ultrasound‐guided tissue acquisition: A case report

et al. 2022

Endobronchial ultrasound (EBUS)‐guided tissue acquisition (TA) performed by transbronchial needle aspiration (TBNA) is the main diagnostic procedure in mediastinal and hilar lymph node (LN) biopsy. EBUS‐guided intranodal forceps biopsy (EBUS‐IFB) and EBUS‐guided cryobiopsy can achieve higher diagnostic yield of lymphomas, uncommon tumors, and benign diseases. However, these techniques require the creation of a tract to insert biopsy devices, which may result in critical complications. Here, we report a rare case of airway stenosis (AS) that occurred after EBUS‐TA for mediastinal LN biopsy. An 80‐year‐old man had multiple pulmonary nodules and an enlarged mediastinal LN. EBUS‐TBNA and EBUS‐IFB were performed for histological diagnosis. Cutaneous adnexal carcinoma (CAC) was diagnosed. The patient underwent chemotherapy. Four months later, he was hospitalized for AS due to a tracheal tumor with dyspnea. Chest computed tomography and bronchoscopy revealed that the tracheal tumor was caused by invasion from the biopsied LN into the tracheal lumen by tract seeding (TS) caused by EBUS‐TA. Cryotherapy was performed. The tracheal tumor was pathologically consistent with CAC and is currently under control with radiotherapy. TS‐associated EBUS‐TA is rare but may increase in frequency with aggressive tissue sampling techniques. Bronchoscopists should perform EBUS‐TA with awareness of the potentially serious complications.

“…Shen et al showed that EBUS-TBNA compared with conventional TBNA has a greater diagnostic yield both for granulomatous and non-granulomatous benign lymphadenopathy, especially when the diameter of the lymph node sampled was lower than 20 mm [ 52 ]. In a single centre study conducted on 100 patients, the use of EBUS-transbronchial fine needle biopsy (TBNB) with Fransen needle had a diagnostic yield of 97% [ 53 ].…”

Role of EBUS-TBNA in Non-Neoplastic Mediastinal Lymphadenopathy: Review of Literature

et al. 2022

Mediastinal lymphadenopathy is a condition in which one or more mediastinal lymph nodes are enlarged for malignant or benign causes, generally more than 10 mm. For a long time, the only way to approach the mediastinum was surgery, while in last decades endoscopic techniques gained their role in neoplastic diseases. At the present time, EBUS is the technique of choice for studying the mediastinum in the suspicion of cancer, while there are not strong indications in guidelines for the study of benign mediastinal lymphadenopathy. We reviewed the literature, looking for evidence of the role of EBUS in the diagnostics of non-neoplastic mediastinal lymphadenopathy, with special regard for granulomatous disease, both infectious and non-infectious. EBUS is a reliable alternative to surgery in non-neoplastic mediastinal lymphadenopathy, even if more evidence is needed for granulomatous diseases other than tuberculosis and sarcoidosis.

“…In a retrospective analysis of the first 100 patients undergoing EBUS with FNB, Balwan et al showed that core biopsy was seen in 87% of patients, the pathological diagnosis was established in 97%, and the diagnostic yield for granulomatous lymphadenopathy was obtained in 95.6%. No patient-related adverse events were noted [ 23 ].…”

Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration (EBUS-TBNA): Technical Updates and Pathological Yield

et al. 2021

View full text Add to dashboard Cite

Since the endobronchial ultrasound bronchoscope was introduced to clinical practice, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become the procedure of choice to sample hilar and mediastinal adenopathy. Multiple studies have been conducted in the last two decades to look at the different technical aspects of the procedure and their effects on the final cytopathological yield. In addition, newer modes of ultrasound scanning and newer tools with the potential to optimize the selection and sampling of the target lymph node have been introduced. These have the potential to reduce the number of passes, reduce the procedure time, and increase the diagnostic yield, especially in rare tumors and benign diseases. Herein, we review the latest updates related to the technical aspects of EBUS-TBNA and their effects on the final cytopathological yield in malignant and benign diseases.
