“…Therefore, it is necessary to develop equipment for increasing the diagnostic yield in the future. Fortunately, updated C-TBNA techniques as well as new types of puncture needles for different puncture sites are now available, which have promoted renewal of C-TBNA 20, 21. In addition, new advanced navigation systems, such as virtual bronchoscopic navigation (VBN) system could be used to evaluate the peribronchial lesions, guide the needle puncture site, angle and depth, as well as reconstruct the large blood vessels around bronchi, and the VBN system offers a more comprehensive and three-dimensional identification, especially in the adjacent relationship between peripheral blood vessels surrounding the lesion as well as the important organs.…”

Background: The diagnosis of peribronchial pulmonary lesions located in the tertiary bronchi, also known as segmental bronchi, as well as, the 4th order and 5th order segmental bronchi is very difficult. Histopathological specimens cannot be easily obtained by endobronchial biopsies (EBBX) due to the patent but small segmental bronchial lumen. The aim of the present study was to evaluate the diagnostic accuracy and safety of the novel technique with radial probe endobronchial ultrasound (R-EBUS) assisted conventional transbronchial needle aspiration (C-TBNA) in the diagnosis of solitary peribronchial pulmonary lesions located in segmental bronchi from 3th to 5th order.Methods: From December 2014 to December 2015, 16 patients with solitary peribronchial pulmonary lesions in the segmental bronchi from 3th to 5th order confirmed by computed tomography (CT) were enrolled. The lesions were located using radial probe endobronchial ultrasound (R-EBUS) to determine the sites of conventional transbronchial needle aspiration (C-TBNA), then, histopathological specimens were obtained using the technique of C-TBNA. The final pathological diagnosis was made based on the findings from the surgical specimens. Statistical analyses were performed for specimen results and complications.Results: On pathological evaluation, 14 of the 16 specimens were malignant, including 8 adenocarcinomas, 4 squamous cell carcinomas, and 2 small cell carcinomas, while 2 were non-malignant diseases. The diagnostic accuracy rate, sensitivity and missed diagnosis rates were 87.5%, 87.5% and 12.5%, respectively. When Combined the results of cytology with histologic samples obtained from C-TBNA the total diagnostic accuracy rate, sensitivity and missed diagnosis rate were 93.75%, 93.75% and 6.25%, respectively. There were 2 cases of bleeding complications >5 mL after C-TBNA, and both were resolved with endobronchial management.Conclusions: The combination of R-EBUS with C-TBNA was advantageous and safe for the diagnosis of solitary peribronchial pulmonary lesions located in the segmental bronchi. However, possible bleeding complications should be anticipated with needle aspiration. Further verification of this combined application should be investigated in larger clinical trials.

“…If we had larger case mix of tumor patients (including lymphoma) this study might have shown a significant advantage of 19 G needle use. 4 In future we may send part of core tissue fragment for AFB culture and it remains to be seen if this improves the accuracy of diagnosis in suspected TB and sarcoidosis. We may also try to adapt our 19 G needle as shown by Wang in his HYBRID EBUS TBNA study published in 2015.…”

Introdution: As the practice of TBNA becomes more widely accepted, it has also revived a longstanding question on the optimum size of needle and whether larger needle with core biopsy is of any additional benefit. In routine practice 19G needle is rarely used even in large nodes as it is perceived to be technically difficult and likely to give a poor yield of representative tissue. We report our experience with yield and safety using 19G needle for Conventional TBNA. Material and methods: Eighteen patients with large mediastinal nodes (short axis > 25 mm) underwent 19G Conventional TBNA and station 4R and/or stations 7 were punctured respectively. Results: Out of Eighteen patients, core biopsy material was inadequate or unrepresentative in 14 / 18 cases and cytology material was unrepresentative in 2 patients. A diagnosis was reached in 16 of 18 patients by smear cytology and in 14 cases by histology. Out of eighteen patients, 12 patients had Granulomatous etiology, 2 had poorly differentiated adenocarcinoma, 1 had Malignant Round Cell Tumor, and one patient had reactive lymphadenitis. Conclusion: The 19G TBNA procedure is effective and safe, and can be a cost-saving alternative to surgical mediastinal exploration. It should be performed after careful case selection during initial diagnostic bronchoscopy and familiarization with the technique should not be neglected in training programmes and workshops.
