[PMID: 38326810 PMCID: PMC10848468 DOI: 10.1186/s13019-024-02560-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2023] [Accepted: 01/30/2024] [Indexed: 02/09/2024] Open
Abstract
BACKGROUND Differential diagnosis of mediastinal lymphadenopathy is an issue of debate. Lymph nodes may be enlarged due to a variety of inflammatory, infectious, or malignant reasons. Therefore, obtaining samples from the affected nodes is crucial for the diagnosis. Usually, these patients are subjected to TBNA (EBUS or conventional) or mediastinoscopy if TBNA is not conclusive. This study evaluated the safety and feasibility of this new technique of transbronchial forceps biopsy for the diagnosis of mediastinal lymphadenopathy. METHODS The study included 18 patients with confirmed mediastinal lymphadenopathy who were admitted in Chest Department, Cairo University in the period from December 2019 to December 2020. All patients were subjected to flexible bronchoscopy with conventional transbronchial needle aspiration (C-TBNA) and transbronchial forceps biopsy (LN-TBFB) from the enlarged mediastinal lymph node in the same procedure. RESULTS we found the technique of LN-TBFB safe with no serious complications. We were able to reach a diagnosis in 7/7 (100%) cases of sarcoidosis, 6/7 (85.7%) cases of malignant lymph nodes. We had three cases where the histopathology showed hyperactive follicular hyperplasia, and a single case of tuberculous lymphadenitis. C-TBNA was diagnostic in 71.4% of sarcoidosis cases, 42.9% of malignant cases, but failed to diagnose the one patient with tuberculous lymphadenitis. CONCLUSION Lymph node transbronchial forceps biopsy (LN-TBFB) was found to be safe and effective in the diagnosis of mediastinal lymphadenopathy. We strongly advocate the use of this minimally invasive technique for diagnosing pathologically enlarged mediastinal lymph nodes, as a last step before mediastinoscopy.

Comparison of cryobiopsy and forceps biopsy for the diagnosis of mediastinal lesions: A randomised clinical trial. Pulmonology 2024:S2531-0437(23)00240-4. [PMID: 38182469 DOI: 10.1016/j.pulmoe.2023.12.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Revised: 12/12/2023] [Accepted: 12/12/2023] [Indexed: 01/07/2024] Open
Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the standard approach for lung cancer staging. However, its diagnostic utility for other mediastinal diseases might be hampered by the limited tissue retrieved. Recent evidence suggests the novel sampling strategies of forceps biopsy and cryobiopsy as auxiliary techniques to EBUS-TBNA, considering their capacity for larger diagnostic samples. METHODS This study determined the added value of forceps biopsy and cryobiopsy for the diagnosis of mediastinal diseases. Consecutive patients with mediastinal lesions of 1 cm or more in the short axis were enrolled. Following completion of needle aspiration, three forceps biopsies and one cryobiopsy were performed in a randomised pattern. Primary endpoints included diagnostic yield defined as the percentage of patients for whom mediastinal biopsy led to a definite diagnosis, and procedure-related complications. RESULTS In total, 155 patients were recruited and randomly assigned. Supplementing EBUS-TBNA with either forceps biopsy or cryobiopsy increased diagnostic yield, with no significant difference between EBUS-TBNA plus forceps biopsy and EBUS-TBNA plus cryobiopsy (85.7 % versus 91.6 %, P = 0.106). Yet, samples obtained by additional cryobiopsies were more qualified for lung cancer molecular testing than those from forceps biopsies (100.0 % versus 89.5 %, P = 0.036). When compared directly, the overall diagnostic yield of cryobiopsy was superior to forceps biopsy (85.7 % versus 70.8 %, P = 0.001). Cryobiopsies produced greater samples in shorter procedural time than forceps biopsies. Two (1.3 %) cases of postprocedural pneumothorax were detected. CONCLUSIONS Transbronchial mediastinal cryobiopsy might be a promising complementary tool to supplement traditional needle biopsy for increased diagnostic yield and tissue harvesting.

Concordance between transbronchial lung cryobiopsy and surgical lung biopsy in patients with idiopathic multicentric Castleman disease: A report of four cases. Respir Investig 2024; 62:1-8. [PMID: 37925882 DOI: 10.1016/j.resinv.2023.09.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 08/02/2023] [Accepted: 09/07/2023] [Indexed: 11/07/2023]
Abstract
BACKGROUND Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disease often associated with pulmonary involvement. Recently, transbronchial lung cryobiopsy (TBLC) has been reported to be useful for the diagnosis of diffuse interstitial lung disease. However, there have been no reports of pathological assessment of TBLC for iMCD. METHOD To clarify the efficacy of TBLC in the diagnosis of iMCD, we retrospectively reviewed four iMCD patients who had undergone both TBLC and surgical lung biopsy (SLB). RESULTS The median age was 44 years; 2 males and 2 females. Two or three TBLC specimens were taken from each patient. All patients had no complications other than minimal bleeding. The size of the TBLC specimens was approximately 5-6 × 3-4 mm, and the alveolar region, and centrilobular and perilobular areas were adequately sampled. As with SLB, the extent of lung lesions and inflammatory cell infiltration could be sufficiently evaluated by TBLC. The presence of lymphoid follicles could also be assessed by TBLC; however, the germinal centers with lymphoid follicles were difficult to evaluate. The TBLC specimens could also be evaluated for immunostaining, especially IgG4 immunostaining, to rule out IgG4-related lung disease. Pulmonary pathological grading showed a high concordance rate between major pathological findings of TBLC and SLB. The pathologist's confidence level of TBLC for the diagnosis of iMCD was high in all cases. CONCLUSIONS TBLC exhibits a high concordance rate with SLB in the pathological evaluation of iMCD, which may be useful for the diagnosis of iMCD.

Abstract
Over the past decade, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has become an indispensable tool in the diagnostic armamentarium of the pulmonologist. As the expertise with EBUS-TBNA has evolved and several innovations have occurred, the indications for its use have expanded. However, several aspects of EBUS-TBNA are still not standardized. Hence, evidence-based guidelines are needed to optimize the diagnostic yield and safety of EBUS-TBNA. For this purpose, a working group of experts from India was constituted. A detailed and systematic search was performed to extract relevant literature pertaining to various aspects of EBUS-TBNA. The modified GRADE system was used for evaluating the level of evidence and assigning the strength of recommendations. The final recommendations were framed with the consensus of the working group after several rounds of online discussions and a two-day in-person meeting. These guidelines provide evidence-based recommendations encompassing indications of EBUS-TBNA, pre-procedure evaluation, sedation and anesthesia, technical and procedural aspects, sample processing, EBUS-TBNA in special situations, and training for EBUS-TBNA.

Respir Med 2023; 208:107131. [PMID: 36720322 DOI: 10.1016/j.rmed.2023.107131] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/19/2022] [Revised: 12/30/2022] [Accepted: 01/26/2023] [Indexed: 01/31/2023]
Abstract
BACKGROUND The Franseen fine needle biopsy tool (Acquire®, Boston Scientific, Boston, MA) may provide better quality specimens than current endobronchial ultrasound-transbronchial needle aspiration (EBUS-TNBA) needles. We performed a comparative retrospective study evaluating the diagnostic yield of the Franseen fine needle biopsy (FNB) versus standard fine needle aspiration (FNA) for benign lymphadenopathy and tissue acquisition for next generation sequencing (NGS) in non-small cell carcinoma (NSCLC). METHODS All EBUS-TBNA procedures performed between January 1st, 2019 to January 1st, 2020 where both the FNB needle and the FNA needle were used were analyzed. All demographic, procedural, and diagnostic data were recorded. The median tumor surface area, tumor cellularity and adequacy for NGS was evaluated for NSCLC specimens. RESULTS A total of 69 target lesions in 66 patients were biopsied with both the FNB and FNA needles. The mean (SD) size of target biopsied was 1.8 cm (0.8); The most common stations were 7 (54%) and 4R (26%). The mean (SD) needle passes were 6 (2.2) and 4 (1.8) with FNA and FNB needles, respectively (p < 0.0001). Benign lymphadenopathy was diagnosed with FNA needle in 46% and in 82% with FNB (p < 0.0001). NGS tissue adequacy was 47% with FNA needle versus 76% with FNB (p = 0.02). Median tumor surface area and tumor cellularity were greater with FNB needle than FNA needle (80 mm2 versus 9 mm2, p = 0.002, and 81% versus 45%, p = 0.0004). CONCLUSION The FNB needle demonstrated higher diagnostic yield in benign lymphadenopathy and higher quality for NGS than standard FNA needle.

Transbronchial needle aspiration combined with cryobiopsy in the diagnosis of mediastinal diseases: a multicentre, open-label, randomised trial. THE LANCET. RESPIRATORY MEDICINE 2023; 11:256-264. [PMID: 36279880 DOI: 10.1016/s2213-2600(22)00392-7] [Citation(s) in RCA: 13] [Impact Index Per Article: 13.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/28/2022] [Revised: 09/09/2022] [Accepted: 09/15/2022] [Indexed: 11/07/2022]
Abstract
BACKGROUND Transbronchial mediastinal cryobiopsy is a novel sampling technique for mediastinal disease. Despite the possibility of lung cancer misdiagnosis, the improved diagnostic yield of this approach for non-lung-cancer lesions compared with standard endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) highlights its diagnostic potential as a complementary technique to conventional biopsy. We aimed to evaluate the safety profile and added value of the combined use of transbronchial mediastinal cryobiopsy and standard EBUS-TBNA for the diagnosis of mediastinal diseases. METHODS We conducted an open-label, randomised trial at three hospital sites in Europe and Asia. Eligible patients were aged 15 years or older, with at least one mediastinal lesion of 1 cm or longer in the short axis that required diagnostic bronchoscopy. Participants were randomly assigned (1:1) using a block randomisation scheme generated by a computer (block size of four participants based on a random table from an independent statistician) to the combined use of EBUS-TBNA and transbronchial mediastinal cryobiopsy (combined group) or EBUS-TBNA alone (control group). Because of the nature of the intervention, neither participants nor investigators were masked to group assignment. The coprimary outcomes were differences in procedure-related complications and diagnostic yield (defined as the proportion of participants for whom mediastinal biopsy led to a definitive diagnosis), assessed in the full analysis set, including all the patients who met the eligibility criteria and had a biopsy. A fully paired, intraindividual diagnostic analysis in participants who had both needle aspiration and mediastinal cryobiopsy was conducted, in addition to interindividual comparisons. This trial is now complete and is registered with ClinicalTrials.gov, NCT04572984. FINDINGS Between Oct 12, 2020, and Sept 9, 2021, 297 consecutive patients were assessed for eligibility and 271 were enrolled and randomly assigned to the combined group (n=136) or the control group (n=135). The addition of cryobiopsy to standard sampling significantly increased the overall diagnostic yield for mediastinal lesions, as shown by both interindividual (126 [93%] of 136 participants in the combined group vs 109 [81%] of 135 in the control group; risk ratio [RR] 1·15 [95% CI 1·04-1·26]; p=0·0039) and intraindividual (126 [94%] of 134 vs 110 [82%] of 134; RR 1·15 [95% CI 1·05-1·25]; p=0·0026) analyses. In subgroup analyses in the intraindividual population, diagnostic yields were similar for mediastinal metastasis (68 [99%] of 69 participants in the combined group vs 68 [99%] of 69 in the control group; RR 1·00 [95% CI 0·96-1·04]; p=1·00), whereas the combined approach was more sensitive than standard needle aspiration in benign disorders (45 [94%] of 48 vs 32 [67%] of 48; RR 1·41 [95% CI 1·14-1·74]; p=0·0009). The combined approach also resulted in an improved suitability of tissue samples for molecular and immunological analyses of non-small-cell lung cancer. The incidence of adverse events related to the biopsy procedure did not differ between trial groups, as grade 3-4 airway bleeding occurred in three (2%) patients in the combined group and two (1%) in the control group (RR 0·67 [95% CI 0·11-3·96]; p=1·00). There were no severe complications causing death or disability. INTERPRETATION The addition of mediastinal cryobiopsy to standard EBUS-TBNA resulted in a significant improvement in diagnostic yield for mediastinal lesions, with a good safety profile. These data suggest that this combined approach is a valid first-line diagnostic tool for mediastinal diseases. FUNDING National Natural Science Foundation of China.

Abstract
OBJECTIVE The diagnostic accuracy and yield of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is not well established in lymphoma and other mediastinal-related diseases. The objective of this study was to examine the yield of a combined technique of EBUS-TBNA and endobronchial ultrasound-guided transbronchial forceps biopsies (EBUS-TBFB) compared with each modality alone in lymphoma and other mediastinal-related diseases. METHODS This was a retrospective review of cases of mediastinal lymphadenopathy of unknown etiology accessed using TBNA and TBFB. The McNemar test was used to compare the diagnostic yield of TBNA, TBFB, and the combined technique. RESULTS The combined approach yielded a definitive diagnosis in 31/35 cases (88.6%). In 9/10 cases (90%), Hodgkin's and non-Hodgkin's lymphomas were diagnosed and subtyped without further need for invasive testing. All of the granulomatous inflammation cases were confirmed using the combined technique. Two cases led to adequate whole-genome sequencing of lung cancer, and one patient was diagnosed as having dedifferentiated liposarcoma despite a nondiagnostic preprocedural mediastinoscopy. There was only one procedure-related complication, a pneumomediastinum that required no further intervention. There were no significant adverse events. CONCLUSIONS The combination of EBUS-TBFB and EBUS-TBNA is safe and provides a high yield in the diagnosis of mediastinal adenopathy of unknown etiology, especially lymphoma. Furthermore, the larger samples obtained from TBFB increased its sensitivity to detect granulomatous disease and provided specimens for clinical trials of malignancy when needle aspirates were insufficient.

Abstract
INTRODUCTION Endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) is a standard procedure in cases of enlarged mediastinal lymph nodes. Recently, new tools were developed aiming to improve the diagnostic yield. A novel crown-cut needle is considered to obtain tissue cores which can be beneficial for the evaluation by the pathologist. This study aimed to compare the novel 22G crown-cut needle with a conventional 22G needle with EBUS guidance in the diagnosis of sarcoidosis. METHODS We designed a single-center prospective randomized clinical trial between March 2020 and January 2021 with 30 patients with mediastinal lymphadenopathy and suspected sarcoidosis. RESULTS 24 patients (mean age 49.5 vs 54.1, mean FVC 73.7% vs 86.7%, mean DLCO 72.4% vs 72.5% for crown-cut needle vs conventional needle, respectively) were diagnosed with sarcoidosis. In the remaining six patients, sarcoidosis was reasonably excluded. The diagnostic yield for sarcoidosis was 77% with the crown-cut needle vs. 82% with the conventional needle (p > 0.05). In patients with histopathologic hallmarks typical of sarcoidosis (n = 19), the crown-cut needle was superior in detecting granulomas (8.3 vs 3.8 per cytoblock, p < 0.05) and histiocytes (502 vs 186 per cytoblock, p < 0.05). Four of seven bronchoscopists experienced difficulties passing through the bronchial wall with the crown-cut needle and one episode of bleeding occurred in this group which made interventions necessary. CONCLUSIONS Despite equivalence in diagnostic accuracy, the crown-cut needle was superior to the conventional needle in detecting granulomas and histiocytes. This indicates greater potential for obtaining higher quality sample material with the crown-cut needle in cases of granulomatous inflammation.

Endobronchial Ultrasound-Guided Transbronchial Forceps Biopsy: A Retrospective Bicentric Study Using the Olympus 1.5 mm Mini-Forceps. J Clin Med 2022; 11:jcm11164700. [PMID: 36012940 PMCID: PMC9410050 DOI: 10.3390/jcm11164700] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 07/31/2022] [Accepted: 08/09/2022] [Indexed: 11/17/2022] Open
Abstract
When evaluating mediastinal/hilar lymphadenopathy (LAD) or masses, guidelines recommend endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) as an initial technique for tissue analysis and diagnosis. However, owing to the small sample size obtained by needle aspiration, its diagnostic yield (DY) is limited. EBUS transbronchial forceps biopsy (TBFB) used as a complimentary technique to EBUS-TBNA might allow for better histopathological evaluation, thus improving DY. In this retrospective bicentric study, we assessed the DY and safety of an EBUS-guided 1.5 mm mini-forceps biopsy combined with EBUS-TBNA for the diagnosis of mediastinal/hilar LAD or masses compared to EBUS-TBNA alone. In total, 105 patients were enrolled. The overall DY was 61.9% and 85.7% for TBNA alone and EBUS-TBNA combined with EBUS-TBFB, respectively (p < 0.001). While the combined approach was associated with a significantly higher DY for lung cancer diagnosis (97.1% vs. 76.5%, p = 0.016) and sarcoidosis (85.2% vs. 44.4%, p = 0.001), no significant differences in DY were calculated for subgroups with smaller sample sizes such as lymphoma. No major adverse events were observed. Using a 1.5 mm mini-forceps is a safe and feasible technique for biopsy of mediastinal or hilar LAD or masses with superior overall DY compared to EBUS-TBNA as a standalone technique.

Abstract
Endobronchial ultrasound (EBUS) bronchoscopy is an established minimally-invasive modality for visualization, characterization, and guidance of sampling of paratracheal and parabronchial structures and tissues. In the intensive care unit (ICU), rapidly obtaining an accurate diagnosis is paramount to the management of critically ill patients. In some instances, diagnosing and confirming terminal illness in a critically ill patient provides needed closure for patients and their loved ones. Currently available data on feasibility, safety, and yield of EBUS bronchoscopy in critically ill patients is based on single center experiences. These data suggest that in select ICU patients convex and radial probe-EBUS bronchoscopy can serve as useful tools in the evaluation of mediastinal lymphadenopathy, central airway obstruction, pulmonary embolism, and peripheral lung lesions. Barriers to the use of EBUS bronchoscopy in the ICU include: (I) requirement for dedicated equipment, prolonged procedure time, and bronchoscopy team expertise that may not be available; (II) applicability to a limited number of patients and conditions in the ICU; and (III) technical difficulty related to the relatively large outer diameter of the convex probe-EBUS bronchoscope and an increased risk for adverse cardiopulmonary consequences due to intermittent obstruction of the artificial airway. While the prospects for EBUS bronchoscopy in critically ill patients appear promising, judicious patient selection in combination with bronchoscopy team expertise are of utmost importance when considering performance of EBUS bronchoscopy in the ICU setting.

Abstract
Background:
Flexible bronchoscopy is essential in diagnosing many pathologic conditions,
and tools such as lavage and biopsies using brushes, forceps, and needles are paramount to
success.
Introduction:
Bronchoscopists worldwide are routinely confronted with questions about such tools
regarding the type, size, utility, costs, safety, anticipated yield, and others. Does the underlying suspected
condition matter to the choice of instruments used? What is the anticipated outcome for benign
versus malignant diseases? These and other questions are raised daily by bronchoscopists.
Methods:
Pubmed was reviewed for research in the English language pertaining to diagnostic bronchoscopy.
The literature is conflicting on the benefits of the types of tools available. The success of
brush biopsies, forceps, and transbronchial needle aspiration is only partially dependent on the size
of the instrument used or its other characteristics. Multiple biopsies are needed, and different approaches
may be complementary in some circumstances.
Results:
By understanding the factors that involve in a biopsy, the bronchoscopist is more likely to
be successful when a crucial diagnosis is mandatory.
Conclusion:
This review aims to be a reference to bronchoscopists everywhere as they contemplate
their approach to flexible diagnostic bronchoscopy.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is preferred for evaluating malignant lymph nodes and staging of lung cancer. Nevertheless, larger tissue samples are increasingly needed, particularly for molecular analysis. We describe the feasibility, technical details, and complications of EBUS-guided transbronchial cryo-node biopsy (TBCNB) in four patients with mediastinal adenopathy. The samples obtained by EBUS-TBCNB in all cases were adequate for histopathological examination (HPE) and immunohistochemistry (IHC) staining. In case 1, HPE showed non-caseating epithelioid granuloma with giant cells and fibrosis consistent with sarcoidosis. Case 2 was diagnosed with adenocarcinoma with positivity for ROS1(D4D6). Case 3 showed features of metastatic adenocarcinoma from the breast (positive for Her2, ER, and GATA3). Case 4 was diagnosed with tuberculosis (necrotizing granuloma in histopathology, stain with Ziehl-Neelsen that showed few rod-shaped bacilli). Only one patient had minimal bleeding at the puncture site controlled with cold saline. There were no adverse events such as major bleeding, pneumomediastinum, or pneumothorax.

Abstract
BACKGROUND Guidelines recommend endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) as an initial investigation technique for mediastinal nodal staging in lung cancer. However, EBUS-TBNA can be limited by the inadequacy of intact tissues, which might restrict its diagnostic yield in mediastinal lesions of certain etiologies. We have previously shown that EBUS-guided transbronchial mediastinal cryobiopsy can provide intact samples with greater volume. METHODS This randomised study determined the diagnostic yield and safety of transbronchial mediastinal cryobiopsy monitored by endosonography for the diagnosis of mediastinal lesions. Patients with mediastinal lesion of 1 cm or more in the short axis were recruited. Following identification of the mediastinal lesion by linear EBUS, fine-needle aspiration and cryobiopsy were sequently performed in a randomised order. Primary endpoints were diagnostic yield defined as the percentage of patients for whom mediastinal biopsy provided a definite diagnosis, and procedure-related adverse events. RESULTS One hundred and ninety-seven patients were enrolled and randomly allocated. The overall diagnostic yield was 79.9% and 91.8% for TBNA and transbronchial mediastinal cryobiopsy, respectively (p=0.001). Diagnostic yields were similar for metastatic lymphadenopathy (94.1% versus 95.6%, p=0.58), while cryobiopsy was more sensitive than TBNA in uncommon tumors (91.7% versus 25.0%, p=0.001) and benign disorders (80.9% versus 53.2%, p=0.004). No significant differences in diagnostic yield were detected between TBNA first and cryobiopsy first groups. We observed 2 cases of pneumothorax and 1 case of pneumomediastinum. CONCLUSIONS Transbronchial cryobiopsy performed under EBUS guidance is a safe and useful approach that offers diagnostic histological samples of mediastinal lesions.

Abstract
BACKGROUND Interventional pulmonology is a rapidly evolving subspecialty of pulmonary medicine that offers advanced consultative and procedural services to patients with airway diseases, pleural diseases, as well as in the diagnosis and management of patients with thoracic malignancy. AREAS OF UNCERTAINTY The institution of lung cancer screening modalities as well as the search of additional minimally invasive diagnostic and treatment modalities for lung cancer and other chronic lung diseases has led to an increased focus on the field of interventional pulmonology. Rapid advancements in the field over the last 2 decades has led to development of various new minimally invasive bronchoscopic approaches and techniques for patients with cancer as well as for patients with chronic lung diseases. DATA SOURCES A review of literature was performed using PubMed database to identify all articles published up till October 2020 relevant to the field of interventional pulmonology and bronchoscopy. The reference list of each article was searched to look for additional articles, and all relevant articles were included in the article. THERAPEUTIC ADVANCES Newer technologies are now available such navigation platforms to diagnose and possibly treat peripheral pulmonary nodules, endobronchial ultrasound in diagnosis of mediastinal and hilar adenopathy as well as cryobiopsy in the diagnosis of diffuse lung diseases. In addition, flexible and rigid bronchoscopy continues to provide new and expanding ability to manage patients with benign and malignant central airway obstruction. Interventions are also available for diseases such as asthma, chronic bronchitis, chronic obstructive pulmonary disease, and emphysema that were traditionally treated with medical management alone. CONCLUSIONS With continued high quality research and an increasing body of evidence, interventional bronchoscopy has enormous potential to provide both safe and effective options for patients with a variety of lung diseases.

Abstract
BACKGROUND Endobronchial ultrasound (EBUS) guided intranodal forceps biopsy (IFB) is considered complimentary to EBUS-TBNA for patients with intrathoracic lymphadenopathy when either additional tissue is requested for comprehensive molecular testing, or for suspected lymphoma and sarcoidosis. This is a systematic review and meta-analysis to investigate the diagnostic yield and complications of combined EBUS-IFB and EBUS-TBNA compared to EBUS-TBNA alone. METHODS We performed a systematic search of MEDLINE, Embase, and Google Scholar for studies evaluating the use of EBUS-IFB for diagnosis of intrathoracic adenopathy, assessing the quality of each study using the QUADAS-2 tool. Using inverse-variance weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed the complications related to the procedure. RESULTS Six observational studies with 443 patients undergoing 467 biopsies were included in the final analysis. Meta-analysis yielded a pooled overall diagnostic yield of 67% (312/467) for EBUS-TBNA and 92% (428/467) for EBUS-TBNA + EBUS-IFB, with an inverse variance - weighted OR of 5.87 (95% CI, 3081 to 9.04, p<0.00001) and an I 2of 15%. The overall complications included pnuemomediastinum (1%), bleeding (0.8%) and respiratory failure (0.6%). The funnel plot analysis illustrated no major publication bias. Subgroup analysis showed increased diagnostic yield for lymphoma (86% vs 30%, p=0.03) and sarcoidosis (93% vs 58%, p<0.00001). CONCLUSIONS The addition of EBUS-IFB to EBUS-TBNA improves the overall diagnostic yield of sampling intrathoracic adenopathy when compared to EBUS-TBNA alone. The complication rates of the combined approach are higher than with EBUS-TBNA, but are reportedly lower than with transbronchial or surgical biopsies.

Abstract
Background Transbronchial needle aspiration (TBNA) is a minimally invasive procedure performed to diagnose lymph node (LN) adenopathy. TBNA with and without endobronchial ultrasound (EBUS) guidance has a high diagnostic yield for malignant LN enlargement, but the value for diagnosing benign LN enlargement has been less thoroughly investigated. Methods We retrospectively evaluated 3540 patients with mediastinal LN enlargement who received TBNA. One hundred sixty-six patients with benign mediastinal lymphadenopathy were included and 293 LNs were biopsied. A positive result was defined as a specific histological abnormality. Conventional TBNA (cTBNA) and EBUS-TBNA, as well as cTBNA and transbronchial forceps biopsy (TBFB), were compared. The subgroup analysis was stratified by disease type and LN size. Results A diagnosis was made in 76.84% of the EBUS-TBNA and 61.31% of the cTBNA (P < 0.05). EBUS-TBNA was superior to cTBNA for both granulomatous (65.18% vs. 45.45%, P < 0.05) and non-granulomatous disease (96.92% vs. 84.06%, P < 0.05). In contrast, the diagnostic yield of EBUS-TBNA was higher than that of cTBNA for LNs < 20 mm (79.44% vs. 64.29%, P < 0.05), but for LNs > 20 mm the difference was marginal. These findings were confirmed in a group of independent patients who received cTBNA plus EBUS-TBNA. The diagnostic yield did not differ between cTBNA and TBFB, but significantly increased to 76.67% when both modalities were employed. Conclusions EBUS-TBNA is the preferred minimally invasive diagnostic method for benign mediastinal LN disease. Combined cTBNA and TBFB is a safe and feasible alternative when EBUS is unavailable.

Abstract
INTRODUCTION Endobronchial biopsy using forceps is generally performed with a standard bronchoscope, while a needle is used with an endobronchial ultrasound (EBUS) bronchoscope. An EBUS video bronchoscope, such as the EB-530US instrument (Fujifilm, Tokyo, Japan), provides good visibility and may, therefore, enable both forceps biopsies and needle aspirations to be performed. OBJECTIVES The aim of this study was to investigate the feasibility of performing forceps biopsies and needle aspirations using the EBUS video bronchoscope for diagnosing endobronchial lesions. METHODS Seventy patients with suspected endobronchial lesions based on a computed tomography scan were recruited and underwent forceps biopsy using the EB-530US EBUS bronchoscope. If the result of a rapid on-site cytological evaluation was negative, an additional needle aspiration of the same lesion or other target lesions was performed. The primary outcome was the completion rate of bronchoscopy, using only the EBUS bronchoscope without removal. RESULTS In the 70 patients, forceps biopsies and/or needle aspirations using the EBUS video bronchoscope were performed and completed without removing the EBUS bronchoscope in 67 patients (95.7%). The remaining three patients required the removal of the EBUS bronchoscope from the trachea (blood clot obstruction of the working channel in one patient and change to a thin bronchoscope to sample an EBUS bronchoscope-inaccessible lesion in two others). The EBUS bronchoscope provided diagnostic material in 66 patients (94.3%). One case each of bleeding and pneumonia were observed (1.4%). CONCLUSION Both forceps biopsy and needle aspiration are feasible using a Fujifilm EB-530US EBUS video bronchoscope.

Endobronchial ultrasound-guided mediastinal lymph node forceps biopsy in patients with negative rapid-on-site-evaluation: A new step in the diagnostic algorithm. CLINICAL RESPIRATORY JOURNAL 2019; 14:314-319. [PMID: 31845474 DOI: 10.1111/crj.13133] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/03/2018] [Revised: 10/07/2019] [Accepted: 12/09/2019] [Indexed: 01/24/2023]
Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) provides a high diagnostic yield in lung cancer, but the yield for benign conditions and lymphoma is lower. The material obtained by EBUS-TBNA is limited by the lack of histopathological samples in some cases. The current 'expanded' aims of mediastinal lymph node (MLN) sampling are both an accurate diagnosis and adequate material for 'targeted' processing in malignant and benign disease. The sample obtained with the 21/22G EBUS needle may not be sufficient in all situations. OBJECTIVES The aim of the study was to evaluate the role of a novel technique for EBUS-guided MLN forceps biopsy (EBUS-TBFB) when EBUS-TBNA with rapid on-site-evaluation (ROSE) failed to provide a diagnosis. In addition, the technical aspects and safety of EBUS-TBFB were studied. METHODS About 30 consecutive patients with enlarged MLN, with a negative EBUS-TBNA ROSE were included. EBUS-TBFB was done by the method described below. The histopathology and complications were recorded. RESULTS Adequate samples for analysis were obtained in all the patients with both EBUS-TBNA and EBUS-TBFB. In patients with a non-diagnostic EBUS-ROSE, EBUS-TBFB led to positive diagnostic results in an additional 8/30 patients (27%). Mild bleeding was noted in two patients who underwent EBUS-TBFB, which resolved with conservative management. The procedure was safe with no major complications. CONCLUSION In patients with a negative EBUS-ROSE, EBUS-TBFB using this technique is safe and augments the diagnostic yield. EBUS-TBFB adds to the armamentarium of EBUS, especially in benign aetiologies of MLN enlargement.

Abstract
RATIONALE Endobronchial ultrasound and transbronchial needle aspiration (EBUS-TBNA) are commonly used for the diagnosis and mediastinal staging of lung cancer. Molecular markers are becoming increasingly important in patients with lung cancer to define targetable mutations suitable for personalized therapy, such as epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK), reactive oxygen species proto-oncogene (ROS1), and programmed death-ligand 1 (PD-L1). OBJECTIVES To evaluate the adequacy of EBUS-TBNA-derived tissue for molecular analysis. METHODS We searched the MEDLINE, LILACS, www.clinicaltrials.gov , and Epistemonikos databases through January 2018. DATA EXTRACTION Two independent reviewers performed the data search, quality assessment, and data extraction. We included both prospective and retrospective studies; risk of bias was evaluated using the ROBINS-I tool. The primary outcome was the proportion of adequate samples obtained by EBUS-TBNA for molecular analysis. Data were pooled by using a binary random effects model. Finally, evidence was rated by using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. RESULTS A total of 33 studies including 2,698 participants were analyzed. In 28 studies that evaluated EBUS-TBNA for the identification of EGFR mutations, the pooled probability of obtaining a sufficient sample was 94.5% (95% confidence interval CI], 93.2-96.4%). For identification of ALK mutations, the pooled probability was 94.9% (95% CI, 89.4-98.8%). Finally, the prevalence of EGFR mutation was 15.8% (95% CI, 12.1-19.4%), and the prevalence of ALK mutation was 2.77% (95% CI, 1.0-4.8%). Data for ROS1 and PD-L1 mutations were not suitable for meta-analysis. CONCLUSIONS EBUS-TBNA has a high yield for molecular analysis of both EGFR and ALK mutations. However, the suitability of TBNA samples for next-generation sequencing is uncertain and should be explored in further studies. Clinical trial registered with PROSPERO (CRD42017080008).

Abstract
Endobronchial ultrasound (EBUS) and transbronchial needle aspiration (TBNA) have changed the landscape of pulmonology. Mediastinal structures beyond the confines of airway walls are visualized in real-time with EBUS, leading to improved accuracy of tissue sampling and diagnostic yield. With the development of various needle sizes ranging from 25-G to 19-G, the sampling of lymph nodes is becoming easier and more commonplace. Yet, certain conditions such as sarcoidosis and lymphoma may still be difficult to diagnose via EBUS-TBNA. Furthermore, in the age of targeted therapy, there are more demands on EBUS-TBNA samples for molecular marker testing and next-generation sequencing. Here, we present a complementary methodology, EBUS-guided intranodal forceps biopsy (EBUS-IFB), for tissue acquisition that may help address these deficiencies. Specifically, we aim to propose indications, contraindications, outline approaches in performing IFB, and provide an overview of the data for this complementary technique.

Abstract
Due to the increasing role of endosonography [endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) and esophageal ultrasound-guided fine needle aspiration (EUS-FNA)] in the diagnosis of several lung diseases, the knowledge of technical aspects is mandatory to optimize the success of the procedure. Among those technicalities related to the procedure, the choice of a needle over another one-either in terms of dimension and type-may have a role in the diagnostic process, especially in some diseases such as lymphoproliferative disorders. In this review, we analyze the current knowledge about the biopsy needle for endosonography, providing also some hints for the future.

Abstract
OBJECTIVE The ProCore ultrasound biopsy needle, used primarily to obtain intra-abdominal tissue core biopsies, has not been widely used for endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this pilot study we evaluated the utility of the ProCore needle for sampling mediastinal or hilar lymph nodes during EBUS-TBNA. DESIGN Thirty-two patients were identified using both ProCore and conventional fine-needle aspiration (FNA) needles for sampling mediastinal or hilar lymph nodes (the study group). Another 33 patients underwent EBUS-TBNA using an FNA needle only (the control group). Specimen satisfactory rates were compared between the study and control groups. Aspirate smears and cell blocks were evaluated for the cellularity of lesional cells and bronchial contamination in a subset of patients in the study group. RESULTS Overall, the ProCore needle did not show additive value to specimen adequacy when comparing the satisfactory rates of the study and control groups (94 vs. 89%). The ProCore needle also did not procure significantly more lesional cells than the FNA needle. CONCLUSION Our experience shows that the ProCore needle does not provide additive value when performing an FNA of mediastinal or hilar lymph nodes. The evaluation of more cases with this new technique is necessary to better determine the clinical utility of using ProCore during EBUS-TBNA.

Abstract
Endobronchial ultrasound has become the first choice standard of care procedure to diagnose benign or malignant lesions involving mediastinum and lung parenchyma adjacent to the airways owing to its characteristics of being real-time and minimally invasive. Although the incidence of lung cancer has been decreasing, it is and will be the leading cause of cancer-related mortality in the next few decades. When compared to other cancers, lung cancer kills more females than breast and colon cancers combined and more males than colon and prostate cancers combined. The type of lung cancer has changed in recent decades and adenocarcinoma has become the most frequent cell type. Prognosis of lung cancer depends upon the cell type and the staging at the time of diagnosis. The cell type and molecular characteristics of adenocarcinoma may allow individualized targeted treatment. Other malignant conditions in the mediastinum and lung (eg, metastatic lung cancers and lymphoma) can be biopsied using endobronchial ultrasound needles. Endobronchial ultrasound needle biopsies provides mostly cytology specimens due to its small sizes of needles (22 gauge or larger) which may not give enough tissue to make a definitive diagnosis in malignant (eg, lymphoma) or benign conditions (eg, sarcoidosis). EchoTip ProCore endobronchial needle released in early 2014 provides histologic biopsy material. Larger tissue biopsies may potentially provide a higher diagnostic yield and it eliminates mediastinoscopy or other surgical interventions. Here we aim to review bronchoscopic approach in the diagnosis of mediastinal lesions with emphasis of EchoTip ProCore needles.

Abstract
BACKGROUND Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration (TBNA) is important in the evaluation of thoracic lymphadenopathy. Reliably providing excellent diagnostic yield for malignancy, its diagnosis of sarcoidosis is inconsistent. Furthermore, TBNA may not suffice when larger "core biopsy" samples of malignant tissue are required. The primary objective of this study was to determine if the sequential use of TBNA and a novel technique called cautery-assisted transbronchial forceps biopsy (ca-TBFB) was safe. Secondary outcomes included sensitivity and successful acquisition of tissue. METHODS The study prospectively enrolled 50 unselected patients undergoing convex-probe EBUS. All lymph nodes exceeding 1 cm were sequentially biopsied under EBUS guidance using TBNA and ca-TBFB. Safety and sensitivity were assessed at the nodal level for 111 nodes. Results of each technique were also reported for each patient. RESULTS There were no significant adverse events. In nodes determined to be malignant, TBNA provided higher sensitivity (100%) than ca-TBFB (78%). However, among nodes with granulomatous inflammation, ca-TBFB exhibited higher sensitivity (90%) than TBNA (33%). On the one hand, for analysis based on patients rather than nodes, 6 of the 31 patients with malignancy would have been missed or understaged if the diagnosis were based on samples obtained by ca-TBFB. On the other hand, 3 of 8 patients with sarcoidosis would have been missed if analysis were based only on TBNA samples. In some patients, only ca-TBFB acquired sufficient tissue for the core samples needed in clinical trials of malignancy. CONCLUSIONS The sequential use of TBNA and ca-TBFB appears to be safe. The larger samples obtained from ca-TBFB increased its sensitivity to detect granulomatous disease and provided adequate specimens for clinical trials of malignancy when specimens from needle biopsies were insufficient. For thoracic surgeons and advanced bronchoscopists, we advocate ca-TBFB as an alternative to TBNA in select clinical scenarios.

Abstract
BACKGROUND Ground-glass opacity (GGO) lesions are difficult to diagnose by transbronchial biopsy (TBB). OBJECTIVES We attempted to diagnose solitary peripheral GGO predominant-type lesions by TBB using endobronchial ultrasonography with a guide sheath (EBUS-GS) under X-ray fluoroscopic guidance, and to evaluate several factors associated with diagnostic yield. METHODS The medical records of 67 patients with GGO predominant-type lesions who underwent TBB using EBUS-GS under X-ray fluoroscopic guidance were retrospectively reviewed. RESULTS Of the 67 lesions, 38 (57%) were successfully diagnosed by EBUS-GS (5/11 pure GGO lesions and 33/56 mixed GGO lesions). The diagnosable lesions were significantly larger than the nondiagnosable lesions (24 vs. 17 mm, respectively; p < 0.01). Regarding the diagnostic yield by signs on computed tomography, the lesions with a bronchus leading directly to a lesion had a significantly higher diagnostic yield than the others (p < 0.05). When GGO lesions were confirmed under X-ray fluoroscopic guidance, the diagnostic yield was 79% (vs. 40% in lesions not visible on X-ray fluoroscopy; p < 0.05). CONCLUSIONS EBUS-GS is a useful and valuable diagnostic modality, even for GGO predominant-type lesions located at the lung periphery.

Abstract
RATIONALE Conventional transbronchial needle aspiration (TBNA) and endobronchial ultrasound (EBUS)-TBNA are widely accepted tools for the diagnosis and staging of lung cancer and the initial procedure of choice for staging. Obtaining adequate specimens is key to provide a specific histologic and molecular diagnosis of lung cancer. OBJECTIVES To develop practice guidelines on the acquisition and preparation of conventional TBNA and EBUS-TBNA specimens for the diagnosis and molecular testing of (suspected) lung cancer. We hope to improve the global unification of procedure standards, maximize the yield and identify areas for research. METHODS Systematic electronic database searches were conducted to identify relevant studies for inclusion in the guideline [PubMed and the Cochrane Library (including the Cochrane Database of Systematic Reviews)]. MAIN RESULTS The number of needle aspirations with both conventional TBNA and EBUS-TBNA was found to impact the diagnostic yield, with at least 3 passes needed for optimal performance. Neither needle gauge nor the use of miniforceps, the use of suction or the type of sedation/anesthesia has been found to improve the diagnostic yield for lung cancer. The use of rapid on-site cytology examination does not increase the diagnostic yield. Molecular analysis (i.e. EGFR, KRAS and ALK) can be routinely performed on the majority of cytological samples obtained by EBUS-TBNA and conventional TBNA. There does not appear to be a superior method for specimen preparation (i.e. slide staining, cell blocks or core tissue). It is likely that optimal specimen preparation may vary between institutions depending on the expertise of pathology colleagues.

Abstract
Lung cancer still remains the leading cause of cancer death among males. Several new methodologies are being used in the everyday practise for diagnosis and staging. Novel targeted therapies are being used and others are being investigated. However; early diagnosis still remains the cornerstone for efficient treatment and disease management. Lung cancer patients requires in many situations intensive care unit (ICU) admission, either due to the necessity for supportive care until efficient disease symptom control (respiratory distress due to malignant pleural effusion) or disease adverse effect management (massive pulmonary embolism). In any case guidelines indicating the patient that has to be intubated have not yet been issued. In the current review we will present current data and finally present an algorithm based on the current published information for lung cancer patients that will probably benefit from admission to the ICU.
