Abstract
INTRODUCTION Transbronchial needle aspiration guided by endobronchial ultrasonography (EBUSTBNA) has the disadvantage of sometimes offering samples of an unsuitable size for an accurate histo-molecular diagnosis. Transbronchial mediastinal cryobiopsy (CRYOEBUS) is a very novel and additional technique to EBUS-TBNA that allows us to obtain larger and quality samples, improving diagnostic performance. MATERIAL AND METHODS Descriptive study of 110 patients with lesions and/or mediastinal lymphadenopathy who underwent EBUS-TBNA and CRYO-EBUS in a single procedure. Our objective was to analyze the diagnostic profitability and safety of the technique. RESULTS CRYO-EBUS obtained samples of 0.42cm on average compared to 0.14cm obtained by EBUS-TBNA. The overall diagnostic performance of the techniques was 60% for EBUS-TBNA and 94.5% for CRYO-EBUS. Furthermore, the latter was more sensitive for the diagnosis of both malignant and benign diseases. With a very high security profile. CONCLUSIONS The CRYO-EBUS technique is cost-effective and safe, and is superior to EBUS-TBNA. Future studies may confirm our findings.

Abstract
EBUS-guided transbronchial mediastinal cryobiopsy (TBMC) has emerged as a promising biopsy tool for diagnosing hilar and mediastinal pathologies. However, several fundamental technical aspects of TBMC remain unexplored. This study aims to determine the optimal number of cryo-passes and freezing time of the ultrathin cryoprobe in EBUS-TBMC concerning specimen size and procedural diagnostic yield. We conducted a retrospective chart review of patients with mediastinal and hilar lesions who underwent EBUS-TBMC between January 2021 and April 2023 across three hospitals in Malaysia. A total of 129 EBUS-TBMC procedures were successfully completed, achieving an overall diagnostic yield of 88.4%. Conclusive TBMC procedures were associated with larger specimen sizes (7.0 vs. 5.0 mm, p < 0.01). Specimen size demonstrated a positive correlation with diagnostic yield (p < 0.01), plateauing at specimen size of 4.1-6.0 mm. A significant positive correlation was also observed between the number of cryo-passes and both specimen size (p < 0.01) and diagnostic yield (p < 0.05). Diagnostic yield plateaued after 2-3 cryo-passes. In contrast, longer freezing times trended towards smaller specimens and lower diagnostic yield, though not reaching statistical significance. The highest diagnostic yield was recorded at the 3.1-4.0 s freezing time. The safety profile of TBMC remains favourable, with one case (0.8%) of pneumothorax and nine cases (7%) of self-limiting bleeding. In our cohort, TBMC performance with 2-3 cryo-passes and a 3.1-4.0 s freezing time to achieve a total aggregate specimen size of 4.1-6.0 mm appeared optimal. Further prospective studies are needed to validate these findings.

Abstract
BACKGROUND Modalities to improve tissue acquisition during endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) have been investigated. Endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC) is a modality to obtain larger histological samples by inserting a cryoprobe into the mediastinal lesion. We aimed to study the diagnostic yield and safety of EBUS-TMC. METHODS We performed a systematic search of the PubMed and Embase databases to extract the relevant studies. We then performed a meta-analysis to calculate the diagnostic yield of EBUS-TMC and compare it with EBUS-TBNA. RESULTS Following a systematic search, we identified 14 relevant studies (869 patients undergoing EBUS-TMC and EBUS-TBNA). We then performed a meta-analysis of the diagnostic yield of EBUS-TMC and EBUS-TBNA from studies wherein both procedures were performed. The pooled diagnostic yield of EBUS-TMC was 92% (95% confidence interval [CI], 89%-95%). The pooled diagnostic yield of EBUS-TBNA was 81% (95% CI, 77%-85%). The risk difference in yield was 11% (95% CI, 6%-15%, I2 = 0%) when EBUS-TMC and EBUS-TBNA were compared. The only complication reported commonly with EBUS-TMC was minor bleeding. The complication rate was comparable with EBUS-TBNA. CONCLUSION EBUS-TMC provides a greater diagnostic yield with a similar risk of adverse events compared to EBUS-TBNA. Future studies are required to clearly establish which patients are most likely to benefit from this modality.

Abstract
The increasing incidence of incidental pulmonary nodules necessitates effective biopsy techniques for accurate diagnosis and treatment planning. This paper reviews the widely used advanced bronchoscopic techniques, such as radial endobronchial ultrasound-guided transbronchial lung biopsy, electromagnetic navigation bronchoscopy, and the cutting-edge robotic-assisted bronchoscopy. In addition, the cryobiopsy technique, which can enhance diagnostic yield by combination with conventional biopsy tools, is described for application to peripheral pulmonary lesions and mediastinal lesions, respectively.

Abstract
Schwannomas are classified as neurogenic tumors and are the most frequent nerve sheath tumors in the paravertebral mediastinum. Recently, the addition of endobronchial ultrasound-guided intranodal forceps biopsy (EBUS-IFB) using standard-sized biopsy forceps (SBFs) to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for metastatic lymph nodes in lung cancer patients reportedly improved the quality and quantity of the obtained specimens without significant complications. However, reports on the usefulness of this technique for benign diseases remain scarce. Here we report a case of schwannoma in the middle mediastinum, which was diagnosed by EBUS-IFB using SBFs, despite inadequate specimens obtained via EBUS-TBNA. An 80-year-old woman presented with dyspnea and a 5-cm sized middle mediastinal tumor. EBUS-TBNA and EBUS-IFB using SBFs were performed for histological diagnosis. No complications were associated with the bronchoscopy procedure, and schwannoma was solely diagnosed using the EBUS-IFB specimens. EBUS-IFB using SBFs is potentially useful for diagnosing benign diseases, including schwannomas, which are often difficult to diagnose with EBUS-TBNA.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is the gold standard in the diagnosis of mediastinal and hilar lesions. For certain purposes, such as the diagnosis and subtyping of lymphoproliferative disorders or molecular pathology, a larger amount of intact sample material is required. EBUS cryobiopsy is a new and efficient tool for this purpose. As it is a new approach, there is still no standardised workflow. In this review, we present the procedure step by step as it is performed at the Ruhrlandklinik in Essen.

Abstract
A 65-year-old man with dyspnea and hemoptysis presented with a right upper lobe mass associated with enlarged mediastinal lymph nodes and bilateral pulmonary nodules on chest computed tomography (CT), suspected lung cancer. Bronchial and CT-guided biopsies revealed poorly differentiated carcinoma. His condition deteriorated rapidly before a definitive diagnosis could be made. Autopsy revealed primary mediastinal choriocarcinoma. Primary mediastinal choriocarcinomas are rare, difficult to diagnose early and have a poor prognosis. In patients with a tumor expanding across the lung and mediastinum and exhibiting pathologic findings of a pooly differentiated carcinoma, we should consider choriocarcinoma, evaluating the serum β-human chorionic gonadotropin levels.

Abstract
Benign and malignant mediastinal lesions are not infrequently encountered in clinical practice. Mediastinoscopy has long been considered the gold standard in evaluating mediastinal pathology. Since its introduction into clinical practice, endobronchial-ultrasonography-guided transbronchial fine needle aspiration (EBUS-TBNA) has replaced mediastinoscopy as the initial procedure of choice to evaluate mediastinal lesions and to stage lung cancer. Its diagnostic yield in benign mediastinal lesions and less common malignancies, however, has remained limited. This has led different proceduralists to investigate additional procedures to improve the diagnostic yield of EBUS-TBNA. In recent years, different published reports concluded that the addition of EBUS-guided intranodal forceps biopsy (IFB) and transbronchial cryobiopsy (TBCB) to EBUS-TBNA increases the diagnostic yield especially in benign mediastinal lesions and uncommon mediastinal malignancies. The purpose of this review is to describe how EBUS-IFB and EBUS-TBCB are performed, to compare their diagnostic yields, and to discuss their limitations and their potential complications. In addition, the review will conclude with a proposed algorithm on how to incorporate EBUS-IFB and EBUS-TBCB into clinical practice.

Abstract
EBUS-TBNA has represented a revolution in the diagnosis of intrathoracic pathologies, particularly in lung cancer staging, replacing more invasive methods such as mediastinoscopy. However, its role in diagnosing rare benign or malignant mediastinal disorders is still a matter of debate. Over the past few years, the role of EBUS-guided cryobiopsy has been increasingly emerging as an innovative and minimally invasive technique in diagnosing these disorders, with an excellent safety profile. In this case report, we present the case of a young man brought to our attention after already undergoing a non-diagnostic trans thoracic needle aspiration (TTNA) procedure for lung consolidations. In our department, he underwent an initial EBUS-TBNA procedure with inconclusive rapid on-site evaluation (ROSE), leading to the decision to perform an EBUS-guided cryobiopsy, which yielded a diagnosis of granulomatosis with polyangiitis without complications. This clinical case demonstrates that in specific contexts, EBUS-cryobiopsy represents an excellent diagnostic tool.

Abstract
BACKGROUND AND OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a diagnostic procedure with adequate performance; however, its ability to provide specimens of sufficient quality and quantity for treatment decision-making in advanced-stage lung cancer may be limited, primarily due to blood contamination. The use of a 0.96-mm miniforceps biopsy (MFB) permits true histological sampling, but the resulting small specimens are unsuitable for the intended applications. Therefore, we introduced a 1.9-mm standard-sized forceps biopsy (SFB) and compared its utility to that of MFB. METHODS We prospectively enrolled patients from three institutions who presented with hilar/mediastinal lymphadenopathy and suspected advanced-stage lung cancer, or those who were already diagnosed but required additional tissue specimens for biomarker analysis. Each patient underwent MFB followed by SFB three or four times through the tract created by TBNA using a 22-gauge needle on the same lymph node (LN). Two pathologists assessed the quality and size of each specimen using a virtual slide system, and diagnostic performance was compared between the MFB and SFB groups. RESULTS Among the 60 enrolled patients, 70.0% were diagnosed with adenocarcinoma. The most frequently targeted sites were the lower paratracheal LNs, followed by the interlobar LNs. The diagnostic yields of TBNA, MFB and SFB were 91.7%, 93.3% and 96.7%, respectively. The sampling rate of high-quality specimens was significantly higher in the SFB group. Moreover, the mean specimen size for SFB was three times larger than for MFB. CONCLUSION SFB is useful for obtaining sufficient qualitative and quantitative specimens.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial cryobiopsy (EBUS-cryobiopsy) is advantageous for collecting larger specimens with minimal crushing; however, it has not been widely used for mediastinal tumors. CASE PRESENTATION A 73-year-old woman with a history of left breast cancer underwent surgery followed by radiotherapy. Computed tomography showed a mass in the anterior mediastinum that was in extensive contact with the sternum on the ventral side and partly with the trachea on the dorsal side. Two computed tomography-guided needle biopsies (CTNBs) were performed on the mass; however, a definitive diagnosis was not made because of severe crush artifacts. Subsequently, we performed EBUS-cryobiopsy and safely obtained sufficient specimen volume with minimal crushing. The histopathological diagnosis was adenocarcinoma, with immunobiological features distinct from those of previous breast cancers. Her overall diagnosis was a rare tumor originating in the anterior mediastinum. CONCLUSIONS EBUS-cryobiopsy can be safely performed in narrow areas surrounded by major blood vessels, and the obtained specimens may be superior to CTNBs for histopathological diagnosis.

Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-TMC), a novel technique, has been reported to improve the diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for mediastinal lesions in recent studies. Current literature suggests that this procedure has greater diagnostic efficacy compared to conventional EBUS-TBNA. This systematic review and meta-analysis aimed to evaluate the diagnostic yield and complications associated with EBUS-TMC in comparison to EBUS-TBNA, thereby exploring the potential of this novel technique in enhancing the diagnostic utility for mediastinal lesions. METHODS A comprehensive literature review was conducted by searching the PubMed, Embase, and Google Scholar databases for articles published from inception to December 31, 2023. The objective of this review was to evaluate the utilization of EBUS-TMC in diagnosing mediastinal disease, while also assessing the quality of each study using the QUADAS-2 tool. The diagnostic yield estimates were subjected to a meta-analysis utilizing inverse variance weighting. Furthermore, a comprehensive analysis of the complications associated with this procedure was performed. RESULTS The meta-analysis included 10 studies involving a total of 538 patients. The findings of the meta-analysis demonstrated that EBUS-TMC yielded an overall diagnostic rate of 89.59% (482/538), while EBUS-TBNA yielded a rate of 77.13% (415/538). The calculated inverse variance-weighted odds ratio was 2.63 (95% confidence interval, 1.86-3.72; p < 0.0001), and I2 value was 11%, indicating a statistically significant difference between the two techniques. The associated complications consisted of pneumothorax, pneumomediastinum, mediastinitis, and bleeding, with an incidence of 0.74% (4/538), 0.37% (2/538), 0.0% (0/538), and 1.12% (6/538), respectively. Moreover, the funnel plot displayed no discernible publication bias. Further subgroup analysis revealed a notable improvement in the diagnosis value for lymphoma (86.36% vs. 27.27%, p = 0.0006) and benign disorder (87.62% vs. 60.00%, p < 0.0001). CONCLUSION This review of the current available studies indicated that EBUS-TMC enhanced overall diagnostic yields compared to EBUS-TBNA, particularly for diagnosing benign disease and lymphoma. This procedure was not associated with any serious complications.

Abstract
Endobronchial ultrasound (EBUS) guided mediastinal cryobiopsy, and intranodal forceps biopsy are newer modalities for sampling mediastinal lymph nodes. The data regarding the diagnostic yield of both modalities is scarce. Patients were recruited retrospectively from our existing database. Patients who had undergone both an EBUS guided mediastinal cryobiopsy and an intranodal forceps biopsy were enrolled in the study. The final diagnosis was made with a clinical-pathological-radiological assessment and clinico-radiological follow-up after one month. A total of 34 patients were enrolled in the study who had undergone both EBUS guided mediastinal cryobiopsy and intranodal forceps biopsy and had complete data available, including 1-month follow-up data. The sample adequacy rate of EBUS-transbronchial needle aspiration (EBUS-TBNA), EBUS-TBNA with mediastinal cryobiopsy, and EBUS-TBNA with intranodal forceps biopsy was 94.11%, 97.05%, and 94.11%, respectively (p=0.56). The diagnostic yield achieved in EBUS-TBNA, EBUS-TBNA with mediastinal cryobiopsy, and EBUS-TBNA with intranodal forceps biopsy was 73.52%, 82.35%, and 79.41%, respectively (p=0.38). No major complications were seen in any patient. To conclude, adding EBUS guided mediastinal cryobiopsy and intranodal forceps biopsy to EBUS-TBNA may not be superior to routine EBUS-TBNA.

Abstract
BACKGROUND Endobronchial Ultrasound (EBUS) has emerged as a crucial tool for diagnosing intrathoracic disorders, particularly in the staging of lung cancer. However, its diagnostic capabilities in the context of benign and rare diseases remain a subject of debate. AIM to investigate the diagnostic yield and safety of EBUS-transbronchial mediastinal cryobiopsy (EBUS-TMC) in comparison to EBUS-transbronchial needle aspiration (TBNA) for a broad spectrum of intrathoracic diseases. METHODS a single-centre retrospective observational study conducted on 48 patients who underwent both EBUS-TBNA and endobronchial ultrasound-transbronchial mediastinal cryobiopsy (EBUS-TMC) in the same procedure between August 2021 and October 2023. RESULTS The overall diagnostic yield of EBUS-TMC surpassed that of EBUS-TBNA (95.8% vs 54.1 %), notably excelling in the diagnosis of sarcoidosis (92.8% vs 78.5 %), rare mediastinal disorders (100% vs 0 %), hyperplastic lymphadenopathy (100% vs 0 %), and lymphoproliferative disease (100% vs 0 %). No significant differences were observed in the diagnosis of NSCLC and SCLC. Samples obtained through EBUS-TMC facilitated the acquisition of NGS and immunohistochemical analyses more readily. CONCLUSION EBUS-TMC may contribute to the precise diagnosis and subtyping of mediastinal diseases, especially lymphomas and rare mediastinal tumors, thereby reducing the number of non-diagnostic procedures.

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.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is considered the investigation of choice for sampling mediastinal nodes. A major drawback of EBUS-TBNA is its lower diagnostic yield for lymphoma and benign diseases. EBUS-guided mediastinal cryobiopsy (EBUS-MCB) is a novel technique that provides larger nodal biopsy samples, with an acceptable safety profile. In this study, we aimed to evaluate the diagnostic yield of EBUS-MCB in patients with an inconclusive rapid on-site evaluation (ROSE). METHODS This is a prospective study of patients who underwent EBUS-TBNA for undiagnosed mediastinal lymphadenopathy. Patients in whom ROSE did not yield a diagnosis (nondiagnostic ROSE) or ROSE revealed scanty atypical cells (inadequate ROSE) were subjected to EBUS-MCB. The diagnostic yield, adequacy, and complications of EBUS-MCB were analyzed. RESULTS Of the 196 patients undergoing EBUS-TBNA, 46 patients underwent EBUS-MCB. Thirty-two cases underwent EBUS-MCB for a nondiagnostic ROSE. EBUS-MCB confirmed the diagnosis in 19/32 (59.3%) cases. The additive diagnostic yield of EBUS-MCB over EBUS-TBNA was 43.7% (14/32 cases). In all 14 cases where EBUS-MCB was performed for an inadequate ROSE, the material obtained by EBUS-MCB was adequate for ancillary studies. The most common complication observed was a minor bleed in 13 cases. CONCLUSION EBUS-MCB has a diagnostic yield of 59.3% when performed in cases with a nondiagnostic EBUS-ROSE. The tissue obtained by EBUS-MCB is adequate for ancillary studies. We propose EBUS-MCB as an additional diagnostic step in cases with an inconclusive ROSE while performing EBUS-TBNA. Larger studies are, however, needed before EBUS-MCB can be incorporated in the diagnostic algorithm for the evaluation of mediastinal lesions.

Abstract
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an established minimally invasive method for the diagnosis of benign and malignant conditions. Continuous efforts are underway to improve the material adequacy of EBUS-TBNA, including the introduction of a new technique called EBUS-guided transbronchial nodal cryobiopsy (EBUS-TBNC). This method allows for the retrieval of larger and well-preserved histologic samples from the mediastinum. We present a case series of four patients who underwent combined EBUS-TBNA and EBUS-TBNC procedures in our centre. All procedures were performed under general anaesthesia using a convex probe EBUS scope (Pentax EB-1970UK). Two patients were diagnosed with malignancy and two with benign disorders (silicosis and tuberculosis). In the malignant cases, both EBUS-TBNA/cell block and cryobiopsy provided a diagnosis but cryobiopsy yielded more material for ancillary tests in one patient. However, in the benign cases, there was discordance between EBUS-TBNA/cell block and cryobiopsy. Only cryobiopsy detected granuloma in the patient with TB (tuberculosis), and in the patient with silicosis, TBNC provided a better overall histological evaluation, leading to a definitive diagnosis. No complications were observed. This case series supports the potential diagnostic value of combining EBUS-TBNA and EBUS-TBNC, particularly in benign mediastinal lesions (granulomatous diseases), and in cases requiring additional molecular tests in cancer diagnosis.

Abstract
PURPOSE OF REVIEW Appropriate staging is of utmost importance in nonsmall cell lung cancer (NSCLC), as the pathologic stage dictates both overall prognosis and appropriate therapeutic pathways. This article seeks to review the current recommendations for mediastinal staging of NSCLC and available modalities to achieve this. Landmark publications pertaining to recent advancements in NSCLC treatments are also highlighted and the role of specific bronchoscopic modalities for tissue acquisition are reviewed. RECENT FINDINGS Recent advancements in the treatment of NSCLC have made accurate mediastinal staging more important than ever. Guidelines and recommendations outlining patients that warrant invasive mediastinal staging are available and a systematic approach should be utilized when sampling is performed. Ensuring the adequacy of tissue for the growing number of molecular biomarkers that must be tested has been the focus of many recent studies. SUMMARY Appropriate mediastinal staging is crucial for the management of patients with NSCLC as is obtaining adequate tissue for diagnostic and therapeutic purposes. EBUS-TBNA is sufficient for the diagnosis of nonsmall cell and small cell lung carcinomas, but EBUS-guided intranodal forceps and cryobiopsy may provide more optimal specimen for patients with benign disease, such as sarcoidosis, or in cases of lymphoma. Further studies are necessary to better delineate the role of these techniques in the diagnosis and staging of mediastinal diseases before they become the primary diagnostic modalities.

The Contribution of Mediastinal Transbronchial Nodal Cryobiopsy to Morpho-Histological and Molecular Diagnosis. Diagnostics (Basel) 2023; 13:3476. [PMID: 37998611 PMCID: PMC10670691 DOI: 10.3390/diagnostics13223476] [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: 10/10/2023] [Revised: 11/15/2023] [Accepted: 11/16/2023] [Indexed: 11/25/2023] Open
Abstract
(1) Background: endobronchial ultrasound-guided mediastinal transbronchial cryo-node biopsy, previously assisted by fine-needle aspiration, is a novel technique of particular interest in the field of lung cancer diagnosis and is of great utility for extrathoracic tumor metastases, lymphomas, and granulomatous diseases. An integrated histological and molecular diagnosis of small samples implies additional difficulty for the pathologist. Additionally, emerging tumor biomarkers create the need to search for new approaches to better manage the tissue sample; (2) Methods: An analytical observational study of 32 mediastinal node cryobiopsies is carried out in 27 patients (n = 27). Statistical analysis using the t-student and Wilcoxon signed-rank tests for paired data is performed with SPSS 26 and R Statistical software. The significance level is established at p < 0.05; (3) Results: cryobiopsies were valid for diagnosis in 25 of 27 patients, with a maximum average size of 3.5 ± 0.7 mm. A total of 18 samples (66.67%) were positive for malignancy and 9 (33.33%) were benign. The tumor percentage measured in all neoplastic samples was greater than 30%. The average DNA and RNA extracted in nine non-small cell lung cancer cases was 97.2 ± 22.4 ng/µL and 26.6 ± 4.9 ng/µL, respectively; (4) Conclusions: the sample size obtained from an endobronchial ultrasound-guided mediastinal transbronchial cryo-node biopsy facilitates the morphological and histo-architectural assessment of inflammatory and neoplastic pathology. It optimizes molecular tests in the latter due to more tumor cells, DNA, and RNA.

Is the diagnostic yield of mediastinal lymph node cryobiopsy (cryoEBUS) better for diagnosing mediastinal node involvement compared to endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)? A systematic review. Respir Med 2023; 218:107389. [PMID: 37579981 DOI: 10.1016/j.rmed.2023.107389] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2023] [Revised: 06/12/2023] [Accepted: 08/11/2023] [Indexed: 08/16/2023]
Abstract
INTRODUCTION New tools such as cryobiopsy of mediastinal lymph nodes (cryoEBUS) have been described to improve the diagnostic usefulness of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). The literature suggests that this novel procedure could be associated with greater diagnostic usefulness than conventional EBUS-TBNA. METHODS To develop a systematic analysis and meta-analysis on the diagnostic diagnostic yield and safety of cryobiopsy of hilar and mediastinal adenopathies compared to EBUS-TBNA. RESULTS Seven studies that had included a total of 555 patients were considered in this review, with 365 (65.7%) of these patients having an etiology of malignant lymph node involvement. The overall diagnostic usefulness of cryoEBUS was higher compared to EBUS-TBNA (92% vs. 80%). However, when the results were analysed according to the specific aetiologies of the adenopathies, cryoEBUS was especially useful in cases of lymphomas or non-pulmonary carcinomas (83% vs. 42%) and in cases that were benign (87% vs. 60.1%), with no significant differences being found in specific cases of lung cancer. For lymphoma, cryoEBUS was diagnostic in 87% of cases compared to 12% for EBUS-TBNA and in addition, also allowed the characterisation of every lymphoma subtype. Genetic studies and immunohistochemical determination of PD-L1 was possible in almost all (97%) of the samples obtained by cryoEBUS, while this was only possible in 79% of those obtained by EBUS-TBNA. The most frequent complication was light bleeding, which was described in up to 85% of cases in some series. CONCLUSION CryoEBUS could represent a promising technique in the diagnostic algorithm used for mediastinal and hilar involvement. Although cryoEBUS did not significantly improve the diagnosis of lung cancer compared to EBUS-TBNA, the results were significantly better in patients with benign pathologies and other tumour types, including lymphomas. In addition, it seems that the samples obtained by cryoEBUS better defined the histological subtypes of lymphoma and allowed complete molecular characterisation in cases of lung cancer. The technique has proven to be safe and no serious complications were described after the procedure.

Cancer Sci 2023; 114:4401-4412. [PMID: 37732498 PMCID: PMC10637053 DOI: 10.1111/cas.15951] [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: 05/06/2023] [Revised: 08/07/2023] [Accepted: 08/21/2023] [Indexed: 09/22/2023] Open
Abstract
Comprehensive genomic profiling (CGP) is implemented to detect actionable gene aberrations and design matched therapies. Although malignant thoracic tumors are commonly detected through respiratory endoscopy, it is questionable whether the small specimens obtained thereof are sufficient for CGP. Therefore, this study aimed to investigate the suitability of respiratory endoscopy for sampling primary and metastatic thoracic tumors for CGP. Patients whose specimens were collected through respiratory endoscopy and assessed by pathologists to determine their suitability for CGP at our institution between June 2019 and May 2022 were reviewed retrospectively. The suitability of each procedure as a sampling technique for CGP and, in the cases actually analyzed, the distribution of the detected gene aberration were assessed. In total, 122 patients were eligible for analysis; the median age was 61 (range, 29-86) years, and 71 (58.2%) patients were male. Primary intrathoracic tumors were found in 91 (74.6%) cases, including 84 (68.9%) primary lung cancers; the remaining thoracic metastases of extrathoracic origin included various types. The suitability rates of specimens obtained using conventional bronchoscopy with and without cryobiopsy, endobronchial ultrasound-guided transbronchial needle aspiration, and medical thoracoscopy were 82.8% (24/29), 70.4% (19/27), 72.9% (35/48), and 100% (18/18), respectively. Of the 96 cases judged suitable, 83 were subjected to CGP, and all but one were successfully analyzed. Finally, 47 (56.6%) patients had at least one actionable gene aberration and eight (9.6%) were treated with the corresponding targeted therapies. In conclusion, specimens obtained through respiratory endoscopy are suitable for CGP; medical thoracoscopy and cryobiopsy in conventional bronchoscopy are particularly useful.

Abstract
INTRODUCTION Endobronchial ultrasonography-guided transbronchial fine-needle aspiration (EBUS-TBNA) has the drawback of providing small sample sizes for accurate diagnosis. Transbronchial mediastinal cryobiopsy (EBUS-TBCB), which allows for larger samples, could improve diagnostic yield. METHODS We prospectively studied 50 patients with mediastinal lymphadenopathy who underwent EBUS-TBNA and EBUS-TBCB in a single procedure. RESULTS EBUS-TBCB improved the diagnostic performance compared with EBUS-TBNA from a definite diagnosis of 32 (64%) patients to 45 (90%) patients [difference 26% (95% confidence interval: 14-40%, p<0.05). EBUS-TBCB was more sensitive to both malignant and inflammatory diseases. EBUS-TBCB produced 6 mild complications resolved during the same procedure. CONCLUSIONS EBUS-TBCB is a cost-effective and safe technique superior to EBUS-TBNA. Future studies could confirm our findings.

Abstract
Cryosurgical techniques are employed for diagnostic and therapeutic bronchoscopy and serve as important tools for the management of pulmonary diseases. The diagnosis of interstitial lung disease requires multidisciplinary team discussions after a thorough assessment of history, physical exam, computed tomography, and lung-function testing. However, histological diagnosis is required in selected patients. Surgical lung biopsy has been the gold standard but this can be associated with increased morbidity and mortality. Transbronchial lung cryobiopsy is an emerging technique and multiple studies have shown that it has a high diagnostic yield with a good safety profile. There is wide procedural variability and the optimal technique for cryobiopsy is still under investigation. There is emerging data that demonstrate that cryobiopsy is safe and highly accurate in the diagnosis of thoracic malignancies. Furthermore, cryorecanalization procedures are a useful adjunct for the palliation of tumors in patients with central airway obstruction. One should keep in mind that these procedures are not free from complications and should be carried out in a specialized center by a trained and experienced bronchoscopy team. We present a review of the literature on the diagnostic and therapeutic utility of bronchoscopy-guided cryosurgical procedures and their safety profile.

Abstract
Despite remarkable advances in tumor response and patient survival in the past decade, systemic immunotherapies for lung cancer result in an objective response in only around half of patients treated. On the basis of this limitation, combination strategies are being investigated to improve response rates. Cryoablation has been proposed as one such technique to induce immunogenic cell death and synergize with systemic immunotherapies, including immune checkpoint inhibitors. Cryoablation has been traditionally delivered percutaneously with imaging guidance although recent technological advances allow for bronchoscopic delivery. Herein, we review the pre-clinical and clinical evidence for the use of cryoablation in non-small cell lung cancer and potential induction of anti-tumor immunity. We highlight ongoing studies involving this approach and propose areas of future investigation.

Abstract
Endobronchial Ultrasound (EBUS) has been widely used to stage lung tumors and to diagnose mediastinal diseases. In the last decade, this procedure has evolved in several technical aspects, with new tools available to optimize tissue sampling and to increase its diagnostic yield, like elastography, different types of needles and, most recently, miniforceps and cryobiopsy. Accordingly, the indications for the use of the EBUS scope into the airways to perform the Endobronchial Ultrasound-TransBronchial Needle Aspiration (EBUS-TBNA) has also extended beyond the endobronchial and thoracic boundaries to sample lesions from the liver, left adrenal gland and retroperitoneal lymph nodes via the gastroesophageal tract, performing the Endoscopic UltraSound with Bronchoscope-guided Fine Needle Aspiration (EUS-B-FNA). In this review, we summarize and critically discuss the main indication for the use of the EBUS scope, even the more uncommon, to underline its utility and versatility in clinical practice.

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.

Abstract
Sedation techniques in interventional flexible bronchoscopy and endobronchial ultrasound-guided transbronchial-needle aspiration (EBUS-TBNA) are inconsistent and the evidence for required general anesthesia under full anesthesiologic involvement is scarce. Moreover, we faced the challenge of providing bronchoscopic care with limited personnel. Hence, we retrospectively identified 513 patients that underwent flexible interventional bronchoscopy and/or EBUS-TBNA out of our institution between January 2020 and August 2022 to evaluate our deep analgosedation approach based on pethidine/meperidine bolus plus continuous flow adjusted propofol, the bronchoscopist-directed continuous flow propofol based analgosedation (BDcfP) in a two-personnel setting. Consequently, 502 out of 513 patients received BDcfP for analgosedation. We identified cardiovascular comorbidities, chronic obstructive pulmonary disease, and arterial hypertension as risk factors for periprocedural hypotension. Propofol flow rate did not correlate with hypotension. Theodrenaline and cafedrine might be used to treat periprocedural hypotension. Moreover, midazolam might be used to support the sedative effect. In conclusion, BDcfP is a safe and feasible sedative approach during interventional flexible bronchoscopy and EBUS-TBNA. In general, after the implementation of safety measures, EBUS-TBNA and interventional flexible bronchoscopy via BDcfP might safely be performed even with limited personnel.

Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has been shown to have a high diagnostic yield for mediastinal and hilar lymph node sampling, particularly in diagnosing and staging non-small cell lung cancer. However, the diagnostic yield is lower in patients with granulomatous and lymphoproliferative disorders. We prospectively compared the feasibility, safety, and diagnostic yield of EBUS-guided lymph node forceps biopsy (EBUS-TBFB) with electrocautery knife compared to EBUS-TBNA of lymph nodes in patients with suspected granulomatous and lymphoproliferative disease. METHODS Patients over 18 years of age with mediastinal/hilar lymph node >10 mm in size in short axis (on CT chest) who had suspected sarcoidosis/lymphoma radiologically/clinically were included in the study. Patients had EBUS-TBNA first with 21 or 22G needles which were followed by biopsy of the node with small forceps (EBUS-TBFB) through the same aspiration site to obtain samples. Electrocautery knife at 20W was used in patients where mucosal penetration was difficult, followed by passage of forceps through that site. RESULTS A total of 30 patients were enrolled in the study, of which 25 patients underwent EBUS-TBFB. Eight patients had a history of lymphoma, one patient had history of squamous cell carcinoma, and one patient had history of chronic lymphocytic leukemia. A 22 gauge needle was used for aspiration in all the cases that were performed, and 1.5 mm or 1.8 mm forceps were used for the biopsy. The use of electrocautery knife at 20W (Olympus America Inc.) was required in 10/25 patients. The EC knife allowed all 10 of those to have successful entry of forceps into the lymph node. The cytology (aspiration from EBUS needle) and histopathology (from forceps) were concordant in 17 patients while it was discordant in eight patients. One patient developed pneumomediastinum after needle and forceps biopsy that required no intervention. CONCLUSION EBUS-guided forceps biopsy is a safe procedure. EC knife did successfully allow forceps entry into the lymph node in all EC knife procedures. The diagnostic yield was 73% (22/30) which improved to 86% (26/30) when both techniques were combined (TBNA and TBFB).

Abstract
Personalized treatment of metastatic non-squamous non-small cell lung cancer (NSCLC) requires detailed molecular characterization of the tumour including detection of predictive driver mutations and programmed death ligand 1 (PD-L1) expression. Complete detection is influenced by the amount of tumour cells sampled as well as their quality. Different sampling techniques may be necessary to provide sufficient tumour material for comprehensive molecular characterization. Missing the detection of targetable molecular genetic aberrations would have a serious impact on the quality of life and prognosis of a patient. This case report highlights the importance of biopsy technique in a patient with NSCLC. Several procedures—pleural puncture, transthoracic lung biopsy and endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA)—could not provide sufficient tumour material for precise tumour characterization. Only the addition of EBUS-guided transbronchial lymph node cryobiopsy (EBUS-TBLNC) enabled complete immunohistochemical and genetic tumour characterization, demonstrating PD-L1 expression in 100% of the tumour cells in the absence of actionable genetic alterations. Based on these results, immunotherapy was initiated.

Abstract
We present the case of a patient with severe complications from mediastinal bleeding after endosonographically guided transbronchial cryobiopsy (EBUS-TBKB) with suspected advanced lymphoma. The EBUS-TBKB is a new effective examination method in interventional pneumology for the diagnosis of diseases with mediastinal lymph node enlargement and intrathoracic tumors, with which large tissue cylinders in the mediastinum can be obtained. Due to the high diagnostic value of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for the clarification of lymphadenopathy, the examination should not be carried out as a routine application. Indications for a primary EBUS-TBKB arise when there is a suspicion of intrathoracic malignant lymphomas or other rare tumors in which extensive unfragmented tissue material is required for diagnosis. A rare complication that has not yet been described in the literature is a hematomediastinum, so that a careful risk assessment of possible bleeding complications should be carried out before intervention and the more invasive mediastinoscopy can be a safer examination method.

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: 23] [Impact Index Per Article: 23.0] [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
Thoracic SMARCA4-deficient undifferentiated tumors (SMARCA4-UT) have a poor prognosis and are often diagnosed at an inoperable advanced stage. Herein, we report a case of SMARCA4-UT diagnosed by endobronchial ultrasound-guided transbronchial cryobiopsy (EBUS-cryo). The patient was a 42-year-old man with a history of smoking. Chest computed tomography revealed a right upper lobe nodule and an enlarged #11s lymph node. Core tissues could not be obtained by EBUS-guided transbronchial needle aspiration (EBUS-TBNA) for diagnosis and mediastinal staging; hence, EBUS-guided intranodal forceps biopsy (EBUS-IFB) was performed. However, a detailed diagnosis beyond poorly differentiated carcinoma could not be obtained. Subsequent EBUS-cryo provided sufficient specimens for immunohistochemical and molecular evaluation and SMARCA4-UT was definitively diagnosed. Thus, EBUS-cryo could be of additional diagnostic value for uncommon tumors, such as SMARCA4-UT, conjointly with EBUS-IFB as well as EBUS-TBNA.

Abstract
The 55th SEPAR Congress was held in Pamplona from 2 to 4 of June 2022. Once again, it was the referral scientific meeting for specialists in pulmonology, thoracic surgery, nursing, physiotherapy, paediatric respiratory diseases and other disciplines involved in respiratory care. The Spanish Society of Pulmonology and Thoracic Surgery showed its national and international leadership in the management of respiratory diseases, which was reflected in a program with an excellent content and a high scientific level. In this review, we offer a summary of some notable aspects covered in six selected areas of interest: pulmonary vascular diseases, non-invasive mechanical ventilation and sleep disorders, asthma, chronic obstructive pulmonary disease (COPD), interstitial lung diseases (ILD), and interventional pulmonolgy and lung transplant.

Abstract
PURPOSE OF REVIEW In the history of bronchoscopy, the advent of flexible transbronchial needle aspiration (TBNA) before and, subsequently, of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA), have represented fundamental events, as they have significantly and definitively changed interventional pulmonology's role in diagnostic and therapeutic work-up of most of thoracic diseases.Purpose of this historical review is to retrace the main stages that have contributed to the development of these two techniques. RECENT FINDINGS TBNA allowed the bronchoscopists to overcome the barrier of the tracheobronchial wall and to obtain samples from hilar-mediastinal lesions. With this additional method, bronchoscopy has become an essential procedure for staging of lung cancer.The advent of echo-bronchoscopes, allowing to perform TBNA under direct ultrasound guidance in real time, further increased the diagnostic yield of this technique. Furthermore, the insertion of the echo-bronchoscope through the oesophagus allowed to extend the landscape of targets to sample, including also para-esophageal lesions, liver metastases, celiac nodes and left adrenal glands.EBUS-TBNA has shown its usefulness not only in the approach to mediastinal lesions, but also in other clinical conditions, such as lung nodules or masses adjacent to the tracheobronchial tree. SUMMARY Despite the obvious advantages of EBUS-TBNA, this technology is not yet available in many centres and countries worldwide. For this reason, TBNA remains a basic technique that must complete the technical background of bronchoscopists and it should not be forgotten.

Abstract
Background Localized inguinal lymphadenopathy often represents lower extremity pathogen infection, while normalized lymphadenopathy is associated with infection regression. We hypothesized that inguinal lymph nodes (LNs) were enlarged in Periprosthetic Joint Infection (PJI) patients and that normalized inguinal LNs would be a promising way to determine the timing of reimplantation. Methods We prospectively enrolled 176 patients undergoing primary and revision hip or knee arthroplasty. All patients underwent ultrasound examination of inguinal LNs preoperatively. The diagnostic value of inguinal LNs in PJI was evaluated by the receiver operating characteristic (ROC) curve. Results The median level of inguinal LNs was 26mm in the revision for PJI group compared with 12 mm in the aseptic revision group (p< 0.0001). The size of the inguinal LNs well distinguishes PJI from aseptic failure (AUC= 0.978) compare with ESR (AUC= 0.707) and CRP (AUC= 0.760). A size of 19mm was determined as the optimal threshold value of the inguinal LNs for the diagnosis of PJI, with a sensitivity of 92% and specificity of 96%. Conclusion Ultrasonic analysis of inguinal LNs is a valuable piece of evidence for the diagnosis of PJI and evaluation of persistent infection.

Abstract
OBJECTIVE To describe a novel transbronchial cryobiopsy technique for mediastinal lesions after initial ultrasound assessment and EBUS-TBNA. MATERIAL AND METHODS Transbronchial cryobiopsy (TBCB) was performed in 35 patients with suspicious mediastinal lesions between November 2020 and September 2022. Age of patients ranged from 22 to 75 years (median 50 [39; 62]). Men-to-women ratio was 13:22. RESULTS According to morphological data, patients with sarcoidosis (n=13), NSCLC (n=7) and metastases of other tumors (n=3) prevailed. There were patients with B-cell lymphoma (n=1), Castleman disease (n=1) and small cell lung cancer (n=2). Among 15 biopsies for immunohistochemical examination, samples were sufficient for final morphological conclusion in 11 (73.3%) cases (95% CI 48.5-89.1). In 4 (11.4%) cases (95% CI 4.5-26), examination was uninformative. Repeated biopsy was performed in 2 cases, and sarcoidosis of thoracic lymph nodes was confirmed. Sensitivity, specificity and accuracy of transbronchial cryobiopsy were 93.3, 100 and 94%, respectively. There were no clinically significant complications. In one case, chest X-ray revealed pneumomediastinum without need for additional treatment. CONCLUSION Transbronchial mediastinal cryobiopsy is a perspective method for diagnosis of mediastinal neoplasms. Apparently, this approach may be advisable in patients with suspected sarcoidosis or lymphoproliferative diseases.

Abstract
Since 2005, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has emerged as a standard pulmonological tool. The procedure is safe and well tolerated by patients, with minimal morbidity and almost no mortality. A previous review on the technique was published in 2012. However, over the last ten years, a number of new studies have been published on "benign" (sarcoidosis, tuberculosis…) as well as "malignant" diseases (lung cancer, metastases of extra-thoracic cancers, search for mutations and specific oncogenic markers…). These developments have led to expanded indications for EBUS-TBNA, with which it is indispensable to be familiar, in terms of "staging" as well as "diagnosis". In view of optimizing lymph node sampling, several publications have described and discussed EBUS exploration by means of newly available tools (biopsy forceps, larger needles…), and proposed interpretation of the images thereby produced. Given the ongoing evolution of linear EBUS, it seemed indispensable that information on this marvelous tool be updated. This review is aimed at summarizing the novel elements we have found the most important.

Abstract
Cryobiopsy is advantageous for collecting larger specimens with minimum crushing compared to forceps biopsy and transbronchial needle aspiration (TBNA), but it has not been widely used for mediastinal tumors. In this report, a leiomyoma of the thoracic esophagus was diagnosed with endobronchial ultrasound-guided transbronchial mediastinal cryobiopsy (EBUS-cryo). An asymptomatic 49-year-old woman had a 2.6-cm sized submucosal tumor (SMT) of the esophagus adjacent to the trachea and left main bronchus. EBUS-TBNA and EBUS-guided intranodal forceps biopsy were performed, followed by EBUS-cryo. The biopsy forceps could not be inserted into the tumor, but the cryoprobe was smoothly inserted. EBUS-TBNA could not obtain enough spindle-shaped tumor cells for immunohistochemical staining, but EBUS-cryo provided sufficient specimens for diagnosing the leiomyoma. Adding EBUS-cryo to EBUS-TBNA has recently been reported to achieve high diagnostic yields for lymphomas, uncommon tumors, and benign diseases. EBUS-cryo seems a valid diagnostic option for esophageal SMTs that are difficult to diagnose with needles and forceps.

Abstract
Etiological diagnosis of mediastinal lymphadenopathy represents a daily challenge. Endosonography (transesophageal and transbronchial ultrasound-guided needle aspiration) is the recommended technique in the first diagnostic work-up and in the mediastinal staging of lung cancer. Despite a good sensitivity, limited amount of collected tissue may hamper molecular assessment in advanced lung cancer and in the diagnosis of lymphoproliferative disorders, fibrotic sarcoidosis, and mycobacterial lymphadenitis. Cryobiopsy, a bronchoscopic technique based on cooling, crystallization, and subsequent collection of tissue, has been successfully employed in the diagnosis of interstitial lung diseases. Cryoprobes provide larger amount of tissue than conventional bronchoscopic sampling tools and might potentially prevent the need for invasive surgical procedures. New applications of the technique (e.g., bronchoscopic diagnosis of peripheral pulmonary lesions and mediastinal lymph nodes) have been recently described in few reports. In a recent issue of the Journal, Genova et al. described five patients who underwent endobronchial ultrasound transbronchial needle aspiration (EBUS-TBNA) followed by ultrasound-guided transbronchial cryobiopsy of mediastinal lymphadenopathy for a suspected malignancy. The authors discussed about the potential added value of mediastinal cryobiopsy on a correct histopathological and molecular assessment in patients with malignancies. EBUS-cryobiopsy could be a promising technique in the diagnostic pathway of mediastinal lymphadenitis. However, cryobiopsy is now available only in few selected centres. The learning curve of the technique adapted to mediastinal ultrasound-guided sampling, the optimal sampling strategy, its true diagnostic accuracy in patients with malignant and benign diseases, as well as its safety, are still largely unclear. Mediastinal cryobiopsy could be complementary rather than alternative to conventional endosonography. Rapid on-site evaluation of EBUS-TBNA could guide subsequent sampling with cryoprobes in case of poor collection of biological material or in case of suspected lymphoproliferative disorders. Further studies should investigate its diagnostic yield, in comparison or in combination with conventional endosonography, in large cohorts of patients with malignant or benign mediastinal lymphadenopthies.

Abstract
INTRODUCTION :Cryobiopsy is a novel diagnostic technique for thoracic diseases which has been extensively investigated over the past 20 years. It was originally proposed for the diagnosis of endobronchial lesions and diffuse parenchymal lung disease due to limitations of conventional sampling techniques including small size and presence of artifacts. AREAS COVERED :We will review recent evidence related to the expanding use of cryobiopsy in thoracic diseases. To identify references, the MEDLINE database was searched from database inception until May 2022 for case series, cohort studies, randomized controlled trials, systematic reviews and meta-analyses related to cryobiopsy. EXPERT OPINION Cryobiopsy has expanding applications in the field of thoracic diseases. Evidence to support transbronchial cryobiopsy as an alternative to surgical lung biopsy is increasing and was recently endorsed as a conditional recommendation by the latest American Thoracic Society guideline update for Idiopathic Pulmonary Fibrosis. Developments in technology and technique, in particular the availability of a 1.1 mm flexible cryoprobe, have extended applications to pulmonary diseases, including diagnosis of interstitial lung diseases, peripheral pulmonary lesions, and lung transplant rejection.

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)‐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.
