Slow-pull capillary technique versus suction technique in endobronchial ultrasound-guided transbronchial needle aspiration for diagnosing diseases involving hilar and mediastinal lymph node enlargement.

ABSTRACT: BACKGROUND:Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a widely used, safe, and accurate technique for obtaining pathological specimens to be used in the diagnosis of diseases involving lung hilar and mediastinal lymph node (LN) enlargement. However, application of the suction technique during EBUS-TBNA remains controversial. In addition, the effectiveness of the slow-pull capillary technique for the diagnosis of pancreatic masses was recently reported. The aim of this study was to compare the diagnostic accuracy of EBUS-TBNA using these two techniques. METHODS:The accuracy, sensitivity, specificity, negative predictive value (NPV), positive predictive value (PPV), and availability of tissue cores of the suction and slow-pull capillary techniques were studied retrospectively in patients who underwent EBUS-TBNA for the diagnosis of diseases involving lung hilar and mediastinal LN enlargement. RESULTS:A total of 97 patients with hilar and mediastinal LN enlargement underwent EBUS-TBNA; 30 patients underwent the suction technique, 56 patients underwent the slow-pull capillary technique, 5 patients underwent both techniques, and 6 patients had failed operations. The accuracy, sensitivity, specificity, NPV, PPV, and the number of tissue cores obtained with the suction and slow-pull capillary techniques were 66.67% versus 85.71% (p?=?0.039), 43.75% versus 85.42% (p??0.05), 59.09% versus 50% (p?>?0.05), 87.5% versus 97.62% (p?>?0.05), and 19 versus 50 (p?=?0.004), respectively. In both univariate and multivariate analyses, the acquisition of tissue core was significantly associated with the diagnostic accuracy of EBUS-TBNA. Moreover, the slow-pull capillary technique was significantly associated with the acquisition of tissue core in EBUS-TBNA. There were no significant differences between the two groups in the blood contamination of samples. CONCLUSIONS:Use of the slow-pull capillary technique in EBUS-TBNA can significantly increase the accuracy related to the diagnosis of diseases involving hilar and mediastinal LN enlargement by improving the acquisition of tissue core.

Project description:ObjectiveEndobronchial ultrasound-guided transbronchial needle aspiration is of diagnostic value in hilar/mediastinal (N1/N2) lymph node staging. We assessed the utility of endobronchial ultrasound-guided transbronchial needle aspiration in lung cancer patients with N1/N2 lymph nodes detected on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography.MethodsFifty lung cancer patients with N1/N2 disease on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography underwent endobronchial ultrasound-guided transbronchial needle aspiration for pathological lymph nodes between November 2012 and April 2015. The diagnostic performance of endobronchial ultrasound-guided transbronchial needle aspiration, lymph node site and size, number of needle passes and complications were evaluated retrospectively from patients' medical records. Malignancy was defined as a maximum standardized uptake value (SUVmax) >2.5.ResultsThe median longest diameter of the 61 lymph nodes (29 subcarinal, 21 right lower paratracheal, 6 left lower paratracheal, 4 right hilar and 1 upper paratracheal) was 23.4 mm (range: 10.4-45.7); the median number of needle passes was 2 (range: 1-5). There were no severe complications. A definitive diagnosis was made by endobronchial ultrasound-guided transbronchial needle aspiration in 39 patients (31 adenocarcinomas, 3 small-cell carcinomas, 2 squamous-cell carcinomas, 3 large-cell neuroendocrine carcinomas). In the remaining 11 patients, the diagnosis was indefinite: insufficient endobronchial ultrasound-guided transbronchial needle aspiration material was collected in two patients and non-specific lymphadenopathy was confirmed by endobronchial ultrasound-guided transbronchial needle aspiration or thoracotomy in the other nine patients. The mean lymph node SUVmax was 7.09 (range: 2.90-26.9) and was significantly higher in true-positive than in false-positive nodes (P < 0.05, t-test). Non-specific lymphadenopathy was diagnosed by expert visual interpretation of (18)F-fluorodeoxyglucose positron emission tomography/computed tomography images in five of the nine patients.ConclusionEndobronchial ultrasound-guided transbronchial needle aspiration accurately diagnoses N1/N2 disease detected on (18)F-fluorodeoxyglucose positron emission tomography/computed tomography.

Project description:BackgroundEndobronchial ultrasound (EBUS)-guided mediastinal/hilar cryobiopsy (MedCryoBx) is a relatively new modality, being combined with EBUS-transbronchial needle aspiration (TBNA) to improve yield in the diagnosis of intrathoracic adenopathy. This meta-analysis aims to investigate the diagnostic yield of MedCryoBx versus EBUS-TBNA for intrathoracic adenopathy.MethodsWe conducted a systematic search using Google Scholar, Embase, and PubMed/MEDLINE for studies about a diagnosis of intrathoracic adenopathy using MedCryoBx and EBUS-TBNA. Two authors separately reviewed studies for inherent bias using the Quality Assessment Data Abstraction and Synthesis-2 (QUADAS-2) tool. Inverse Variance weighting for random effects methodology was used for meta-analysis. Pooled diagnostic yields overall and for subgroups were estimated. Complications of MedCryoBx were reviewed.ResultsTen studies with 844 patients undergoing either biopsy procedure were in the final analysis. A total of 554 patients underwent MedCryoBx and 704 patients EBUS-TBNA. Meta-analysis showed a pooled diagnostic yield of 91% (504 of 554) for MedCryoBx and 81% (567 of 704) for EBUS-TBNA, with odds ratio (OR) of 2.5 [95% confidence interval (CI): 1.6 to 3.91; P<0.001], with I2 of 20%. Subgroup analysis for benign conditions showed increased diagnostic yield with OR of 7.95 (91% MedCryoBx versus 58% EBUS-TBNA, P<0.001) with an I2 of 25%. Subgroup analysis for lymphoma showed a statistically significant increase in pooled diagnostic yield with OR of 11.48 (87% MedCryoBx versus 29% EBUS-TBNA, P=0.001). Mild bleeding (36.5%) without any intervention was the most common complication. Bleeding requiring intervention (0.7%) was noted in patients. Pneumothorax (0.4%) and pneumomediastinum (0.4%) were less common in this analysis.ConclusionsMedCryoBx is a very promising tool for the diagnosis of intrathoracic adenopathy. It has improved diagnostic yield over EBUS-TBNA in benign and possibly lymphoproliferative diseases, but less so in lung cancer. The complication rates with MedCryoBx are comparable to EBUS-TBNA.
