Abstract
INTRODUCTION Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) can be limited by the inadequacy of intact tissues, especially in patients with lymphoma, sarcoidosis, and lymph node tuberculosis. A novel technique called transbronchial node biopsy (TBNB) by forceps or cryoprobe has been proposed and studied to improve specimen quality and diagnostic yield. We performed a systematic review of studies describing the safety and sensitivity of EBUS-TBNB versus EBUS-TBNA in diagnosing intrathoracic lymphadenopathy/masses. METHODS We systematically searched MEDLINE, Embase, Cochrane, and China National Knowledge Infrastructure to identify studies focusing on the application of EBUS-TBNB for diagnosis of intrathoracic lymphadenopathy. The quality of each study was evaluated using the QUADAS-2 tool. Using inverse-variance (I-V) weighting, we performed a meta-analysis of diagnostic yield estimations. We also reviewed the complications related to the procedure. RESULTS Thirteen studies were included in the final analysis. The meta-analysis yielded a pooled overall diagnostic yield of 77.80% (939/1,207) for EBUS-TBNA and 86.01% (834/958) for EBUS-TBNB, with an inverse-variance-weighted odds ratio of 3.13 (95% confidence interval [CI], 1.61-6.01; p = 0.0008) and I2 of 82%. The pooled diagnostic yield of EBUS-TBNB versus EBUS-TBNA for the diagnosis of malignancy (including primary lung cancer and extrapulmonary malignancy) was 84.53% (590/698) for EBUS-TBNA and 90.84% (476/524) for EBUS-TBNB, with an I-V-weighted OR of 2.33 (95% CI, 1.15-4.74; p = 0.02) and I2 of 64%. The pooled diagnostic yield of EBUS-TBNB versus EBUS-TBNA for the diagnosis of benignancy was 71.19% (252/354) for EBUS-TBNA and 86.62% (233/269) for EBUS-TBNB, with an I-V-weighted OR of 4.39 (95% CI, 2.00-9.65; p = 0.002) and I2 of 59%. The overall complications included bleeding (n = 11, 0.90%), pneumomediastinum (n = 6, 0.49%), pneumothorax (n = 6, 0.49%), pneumonia (n = 4, 0.33%), respiratory failure (n = 1, 0.08%), and haemoptysis (n = 1, 0.08%). The funnel plot analysis illustrated no major publication bias. CONCLUSIONS EBUS-TBNB improves the overall diagnostic yield of sampling intrathoracic lymphadenopathy and mass lesions relative to EBUS-TBNA. The complication rate of EBUS-TBNB is higher than that of EBUS-TBNA but reportedly lower than that of surgical biopsies.

J Cardiothorac Surg 2024; 19:69. [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.

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.

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
RATIONALE Amyloidosis is a rare disease characterized by the misfolding of autologous proteins and extracellular deposition of fibrils, which can involve 1 or more vital organs in the body. Nodular pulmonary amyloidosis with extensive pulmonary cysts is even less common. This study discusses the diagnosis and treatment of a case of pulmonary nodular amyloidosis with extensive pulmonary cysts and calcification in the middle of the cysts on chest computed tomography, and reviews the related literature. We hope that this rare case will raise awareness of this disease among clinicians. PATIENT CONCERNS Multiple pulmonary nodules and cysts were found on computed tomography of the chest, and the patient was eager to further clarify the nature of the nodules and the next treatment plan. DIAGNOSES Amyloidosis of pulmonary nodules. INTERVENTIONS AND OUTCOMES Since the patient's primary lesion was outside the bronchial lumen near the hilum, we opted for endobronchial ultrasound-guided tunnel biopsy to obtain pathological specimens, and confirmed the diagnosis of nodular pulmonary amyloidosis. After a definite diagnosis, the patient was regularly followed without any specific treatment. LESSONS For patients with multiple pulmonary nodules combined with extensive pulmonary cysts, we also need to be alert to the possibility of pulmonary nodule amyloidosis. Secondly, when the main lesion is located outside the bronchial cavity near the hilum of the lung, the method of pathological tissue biopsy should also consider endobronchial ultrasound-guided tunnel biopsy.

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.

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
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.

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
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
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
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
PURPOSE Interventional pulmonology is a growing subspecialty of pulmonary medicine with flexible and rigid bronchoscopies increasingly used by interventional pulmonologists for advanced diagnostic and therapeutic purposes. This review discusses different technical aspects of anesthesia for interventional pulmonary procedures with an emphasis placed on pharmacologic combinations, airway management, ventilation techniques, and common complications. SOURCE Relevant medical literature was identified by searching the PubMed and Google Scholar databases for publications on different anesthesia topics applicable to interventional pulmonary procedures. Cited literature included case reports, original research articles, review articles, meta-analyses, guidelines, and official society statements. PRINCIPAL FINDINGS Interventional pulmonology is a rapidly growing area of medicine. Anesthesiologists need to be familiar with different considerations required for every procedure, particularly as airway access is a shared responsibility with pulmonologists. Depending on the individual case characteristics, a different selection of airway method, ventilation mode, and pharmacologic combination may be required. Most commonly, airways are managed with supraglottic devices or endotracheal tubes. Nevertheless, patients with central airway obstruction or tracheal stenosis may require rigid bronchoscopy and jet ventilation. Although anesthetic approaches may vary depending on factors such as the length, complexity, and acuity of the procedure, the majority of patients are anesthetized using a total intravenous anesthetic technique. CONCLUSIONS It is fundamental for the anesthesia provider to be updated on interventional pulmonology procedures in this rapidly growing area of medicine.

Abstract
The diagnosis and staging of patients with lung cancer has relied on tissue sampling. Endobronchial ultrasound (EBUS) is a minimally invasive procedure for the rapid and safe acquisition of tissue and can be done easily and repeatedly. EBUS transbronchial needle aspiration (TBNA) is now the standard for diagnosis of mediastinal and hilar lymphadenopathy and should be considered in patients who have a high probability of lymph node metastases without systemic involvement. EBUS also provides guidance for biopsy of peripheral lung lesions. Recent advances of EBUS with new techniques help to improve the diagnostic yield and decrease the complication rate and total procedure time.

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
OBJECTIVES This study aimed to investigate the additional diagnostic value of endobronchial biopsy (EBB) in the diagnosis of pulmonary sarcoidosis. MATERIALS AND METHODS This retrospective cross-sectional study included 59 patients with a preliminary diagnosis of sarcoidosis who were admitted to the Pulmonary Diseases Outpatient Clinic of a tertiary healthcare center between January 2005 and October 2012. The socio-demographic characteristics of the patients as well as clinical and radiological findings were recorded. All patients, irrespective of the presence of an endobronchial lesion (EBL), underwent fiberoptic bronchoscopy (FOB); two to four specimens were taken using EBB from the carina of the right middle lobe in the patients with EBL. RESULTS Of the patients, 39 (66.1%) had normal bronchoscopic findings, while 5 had EBL. Diagnosis was based on EBB in 11 patients (18.6%). Six patients (15.3%) with normal bronchial mucosae were pathologically diagnosed by EBB. There was no statistically significant relationship between the diagnostic ratio of EBB and disease stage, extrapulmonary involvement, FOB findings, elevated lymphocyte rate in bronchoalveolar lavage (≥ 13%), a CD4/CD8 ratio of ≥ 3.5, and serum angiotensin-converting enzyme (ACE) level (p> 0.05). CONCLUSION EBB not only offers the advantage of a high diagnostic ratio in patients with mucosal abnormalities but also contributes to pathological diagnosis in patients with normal mucosa. We recommend using EBB to support diagnosis with a low complication rate for patients undergoing FOB with a preliminary diagnosis of sarcoidosis in healthcare centers, where endobronchial ultrasound (EBUS) is unavailable.

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 is the leading cause of cancer-related mortality worldwide. Standard bronchoscopy has limited ability to accurately localise and biopsy pulmonary lesions that cannot be directly visualised. The field of advanced diagnostic bronchoscopy is rapidly evolving due to advances in electronics and miniaturisation. Bronchoscopes with smaller outer working diameters, coupled with miniature radial and convex ultrasound probes, allow accurate central and peripheral pulmonary lesion localisation and biopsy while at the same time avoiding vascular structures. Increases in computational processing power allow three-dimensional reconstruction of computed tomographic raw data to enable virtual bronchoscopy (VB), providing the bronchoscopist with a preview of the bronchoscopy prior to the procedure. Navigational bronchoscopy enables targeting of peripheral pulmonary lesions (PPLs) via a "roadmap", similar to in-car global positioning systems. Analysis of lesions on a cellular level is now possible with techniques such as optical coherence tomography (OCT) and confocal microscopy (CM). All these tools will hopefully allow earlier and safer lung cancer diagnosis and in turn better patient outcomes. This article describes these new bronchoscopic techniques and reviews the relevant literature.

Abstract
The high diagnostic yield and favorable safety profile of endobronchial ultrasound-guided transbronchial forceps biopsy of the mediastinal lymph nodes have been recently demonstrated. We report an unusual technical problem during endobronchial ultrasound-guided transbronchial forceps biopsy that could be a prerequisite for severe complications. A rupture of the steering band precluded closure of the forceps jaws opened in the subcarinal lymph node. A solution to the problem is presented, together with other procedure-related complications reported in the literature. The report emphasizes that a dysfunction of the forceps steering band can result in severe complications when it occurs during transbronchial sampling of mediastinal lesions.

Abstract
This paper develops a new bronchoscopic ultrasound navigation system that fuses multimodal sensory information including preoperative images, bronchoscopic video sequences, ultrasound images, and external position sensor measurements. To construct such a system, we must align these information coordinate systems. We use hand-eye calibration to align the video camera and its attached external sensor and introduce a phantom-free method to calibrate the ultrasonic probe and its fixed external sensor. More importantly, we propose a marker-free registration method that uses the bronchoscope and the bronchial tree center information to register the sensor and the pre-operative coordinate systems. We constructed a bronchial phantom to validate our system, whose navigation accuracy was about 2.6 mm. Furthermore, compared to the current navigated bronchoscopy, the main advantage of our system is that it navigates the bronchoscope and the ultrasonic mini probe simultaneously and provides bronchial structures inside and outside the bronchial walls, particularly lymph node structures in ultrasonic images.

Abstract
INTRODUCTION Endobronchial ultrasonography (EBUS)-guided fine-needle aspiration (FNA) is increasingly used to sample central lung lesions and mediastinal lymphadenopathy. We investigate the utility of EBUS-guided FNA and concomitant rapid on-site evaluation (ROSE) to diagnose granulomas, the morphologic characteristics of granulomas on ROSE, and how the diagnosis of granulomas changed the clinical impression. MATERIALS AND METHODS All pathologic reports and associated clinical records of patients who had EBUS-guided FNA of the lungs or mediastinal lymph nodes that yielded granulomas were reviewed with at least a 1-year follow-up after EBUS-guided FNA. All ROSE slides were rereviewed to evaluate granulomas for quantity, necrosis, and cohesion. RESULTS Over a 3-year period, 882 EBUS-guided FNAs were performed. One hundred and twelve patients (49% male, average age 50.8 years, range 16-83) had 161 EBUS-guided FNAs that yielded granulomas (18%). The etiologies of the granulomas were as follows: sarcoidosis (54%), infection (12%), malignancy (5%), inflammatory bowel disease-related lymphadenopathy (1%), and no specific clinical etiology (28%). Of the patients with EBUS-guided FNAs, 98 had ROSE performed (87.5%) and granulomas were seen in 70 of these patients (71%). Granulomas associated with sarcoidosis were mostly well-formed and non-necrotizing (90%). The results of the EBUS-guided FNA changed or redefined the clinical diagnosis in 79 patients (71%). CONCLUSIONS EBUS-guided FNA with concurrent ROSE is a useful technique for the diagnosis of granulomas. The quality and quantity of granulomas detected during ROSE may suggest an etiology and help direct ancillary testing.

Abstract
As an evolving technique, linear endobronchial ultrasound is becoming the first choice and standard of care not only to diagnose the malignant and benign mediastinal lesions but also to stage non-small cell lung cancer. Lung cancer is the leading cause of cancer-related mortality in both men and women. The disease causes more death compared with colorectal, breast, and prostate cancers combined in the United States. Staging of lung cancer determines the prognosis. The type of lung cancer has changed in the past few decades. The frequency of adenocarcinoma has increased, whereas squamous cell carcinoma now is less frequent. Determining the cell type and its molecular characteristics allow targeted treatments in adenocarcinoma. The diagnosis of indeterminate mediastinal lymph nodes or masses and staging lung cancer might be challenging. This article will review the principles and clinical utility of endobronchial ultrasound in mediastinal lesions.

Abstract
BACKGROUND/PURPOSE Isolated intrathoracic lymphadenopathy (IT-LAP) is clinically challenging because of the difficult anatomic location and wide range of associated diseases, including tuberculosis (TB). Although sampling via endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) for histopathology is a major development, there is still room for improvement. This study aimed to investigate an algorithmic approach driven by EBUS-TBNA and conventional bronchoscopy to streamline the management of IT-LAP. METHODS Eighty-three prospectively enrolled patients with IT-LAP were subjected to an EBUS-TBNA diagnostic panel test (histopathology, cytology, and microbiology) and underwent conventional bronchoscopy for bronchoalveolar lavage. The results were structured into an algorithmic approach to direct patient treatment, workup, or follow-up. RESULTS The diagnostic yields of EBUS-TBNA based on histopathology were similar for each disease entity: 77.8% for malignancy, 70.0% for TB, 75.0% for sarcoidosis, 80.0% for anthracosis, and 70.0% for lymphoid hyperplasia (p = 0.96). The incidence of malignancy was 10.8% for total IT-LAP patients, and 12.0% and 33.7% for patients with TB and sarcoidosis, respectively. Thirty-five (42.2%) patients were symptomatic. The leading diagnosis was sarcoidosis (60%), followed by TB (20%), malignancy (11.4%), lymphoid hyperplasia (5.7%), and anthracosis (2.9%). By logistic regression analysis, granulomatous disease (odds ratio: 13.45; 95% confidence interval: 4.45-40.67, p < 0.001) was an independent predictor of symptoms. Seven (8.4%) and three (3.6%) IT-LAP patients diagnosed active TB and suggestive of TB with household contact history, respectively, were all placed on anti-TB treatment. CONCLUSION The algorithmic approach streamlines patient management. It enables early detection of malignancy, correctly places nonmalignant patients on an appropriate treatment regimen, and particularly identifies candidates at high risk of TB reactivation for anti-TB chemoprophylaxis.

Abstract
The term "interventional pulmonology" (IP) supersedes the previously used term "thoracic endoscopy," a change that reflects the evolution of a specialty devoted to performing highly sophisticated and technologically advanced procedures in the lungs and chest. Continuing advances in technology promise to further expand IP's diagnostic and therapeutic frontiers. However, standardized educational programs to train and test IP physicians will be essential to maintain a high standard of practice in the field.

Abstract
Endobronchial ultrasound (EBUS) has emerged as a routinely performed procedure in diagnostic bronchoscopy. Extending the view beyond the airway wall, EBUS provides evaluation of tumor involvement of tracheobronchial wall and mediastinum and plays an essential role as a guidance technique for peripheral pulmonary diseases. The latest development is the EBUS-transbronchial needle aspiration (TBNA) scope that allows performing real-time EBUS-TBNA of enlargerd hilar and mediastinal lymph nodes.
