Abstract Background: Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a standard method for obtaining specimens of mediastinal and hilar lesions, and several types of needle of various sizes and materials are available. This study aimed to compare the utility and safety of two needles, cobalt chromium (CC) and stainless steel (SS), for EBUS-TBNA. Methods: This retrospective study included data of patients who underwent EBUS-TBNA with a 22-gauge needle made from either SS (38 patients, 121 punctures) or CC (39 patients, 145 punctures), and procedure time, histological data, complication rates were compared. Results: There were no significant differences between the groups in the baseline characteristics of the patients or lesions or in the complication rates. Although diagnostic yields in each patient who underwent EBUS-TBNA with the two needle types were similar, significantly shorter procedure time (22 min vs. 26 min, p = 0.007), diagnostic histologic sampling yield in each sample (71.0% vs. 58.7%, p = 0.039), fewer samples with cartilage alone (1.4% vs. 6.6%, p = 0.047) and fewer samples containing cartilage (7.6% vs. 16.5%, p = 0.034) were seen in the CC group compared with that in SS needle group. Conclusion: Compared with SS needles, CC needle for EBUS-TBNA showed significant shorter procedure time and higher ratio of getting diagnostic histological specimens in each sample. This might be because of better ability of CC needle to puncture through the trachea and bronchial cartilage to get appropriate lymph node sampling.

Abstract Background Endobronchial ultrasound-guided transbronchial needle aspiration is a standard method for obtaining specimens of mediastinal and hilar lesions. Several types of needles of various sizes and materials are available. This study aimed to compare the quality of specimens collected using two needles, cobalt chromium and stainless steel for endobronchial ultrasound-guided transbronchial needle aspiration. Methods This retrospective study included data of patients who underwent EBUS-TBNA with a 22-gauge needle made from either stainless steel (41 lesions, 121 punctures) or cobalt chromium (47 lesions, 145 punctures). Histological data per puncture, diagnostic yield per lesion, procedure time and complication rates were compared. Results There were no significant differences between the groups in the baseline characteristics of the patients or lesions or in the complication rates. The rate of diagnostic histological specimens in each sample (71.0% vs. 58.7%, P = 0.039), fewer samples with cartilage alone (1.4% vs. 6.6%, P = 0.047) and fewer samples containing cartilage (7.6% vs. 16.5%, P = 0.034) were seen in the cobalt chromium needle group than in the stainless steel needle group. In both groups, the rate of specimens that only contained blood clots in each sample and diagnostic yield per lesion were similar, but the procedure time was significantly shorter (22 min vs. 26 min, P = 0.007) in the cobalt chromium needle group. Conclusion Compared with stainless steel needles, cobalt chromium needle for EBUS-TBNA showed lower cartilage contamination and a higher ratio of obtaining diagnostic specimens in each sample. Bronchoscopists should consider using the optimal needle gauges and materials for collecting adequate specimens.

The purpose of this study was to assess the efficacy of using rapid on-site evaluation (ROSE) for samples taken during endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) at Austin Health, Victoria. This was compared to data collected for cases performed without ROSE. A retrospective analysis was conducted on 188 consecutive patients who underwent EBUS-TBNA from May 2012 to July 2014 whose data was collected prospectively at the time of the procedure. The presence of a cytologist during ROSE resulted in a significant reduction in the number of lesions sampled [mean: 1.5 ± 0.7 (1, 4) versus 1.9 ± 0.8 (1, 4), P = 0.0020] and the number of TBNAs required per case [mean: 3.6 ± 1.4 (1, 8) versus 4.2 ± 1.5 (1, 8), P = 0.0017]. This could potentially result in a shorter procedure time and, ultimately, a reduction in complication rate. The quality of the samples obtained during EBUS-TBNA with ROSE was higher. A larger proportion of samples yielded a satisfactory cell block allowing the potential benefit of additional pathology testing including immunohistochemistry and molecular pathology. In summary, the use of ROSE during EBUS-TBNA was superior to off-site cytological assessment of bronchoscopy specimens.

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.

Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is now a standard of care to sample mediastinal lymph nodes and masses with high diagnostic accuracy and low complication rates. However, the procedure has potential complications that might be life-threatening. Here, we present the first case of Propionobacterium acnes (P. acnes) causing mediastinitis following EBUS-TBNA of a subcarinal lymph node.

A 27-year-old man was diagnosed with inflammatory myofibroblastic tumor, and multiple lymph node and subcutaneous metastases. After several administrations of anti-tumor therapy, he underwent mediastinal lymph node biopsy using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) to confirm tumor relapse. Five weeks later, he complained of chest pain, then rapidly developed shock due to acute pericarditis. Although he was treated with antibiotics for anaerobic bacterial infection and cardiac drainage, mediastinal lymph node abscess and pericarditis did not improve. After the surgical procedure, his physical condition dramatically improved and he was treated with another molecularly targeted therapy. Pericarditis associated with EBUS-TBNA is extremely rare. In this case, salvage was achieved by surgical drainage of the lymph node abscess and pericarditis, and long survival was obtained with further administration of anti-tumor treatment.
