Background EBUS-guided transbronchial needle aspiration (TBNA) is important in the evaluation of thoracic lymphadenopathy. Reliably providing excellent diagnostic yield for malignancy, its diagnosis of sarcoidosis is inconsistent. Furthermore, when larger “core” biopsy samples of malignant tissue are required, TBNA may not suffice. The primary objective of this study was to determine if the sequential use of TBNA and a novel technique called cautery-assisted transbronchial forceps biopsies (ca-TBFB) was safe. Secondary outcomes included sensitivity and successful acquisition of tissue. Methods Fifty unselected patients undergoing convex probe EBUS were prospectively enrolled. Under EBUS guidance, all lymph nodes ≥ 1 cm were sequentially biopsied using TBNA and ca-TBFB. Safety and sensitivity were assessed at the nodal level for 111 nodes. Results of each technique were also reported on a per-patient basis. Results There were no significant adverse events. In nodes determined to be malignant, TBNA provided higher sensitivity (100%) than ca-TBFB (78%). However, among nodes with granulomatous inflammation, ca-TBFB exhibited higher sensitivity (90%) than TBNA (33%). For analysis based on patients rather than nodes, 6 of the 31 patients with malignancy would have been missed or understaged if the diagnosis was based on samples obtained by ca-TBFB. On the other hand, 3 of 8 patients with sarcoidosis would have been missed if analysis was based only on TBNA samples. In some cases only ca-TBFB acquired sufficient tissue for the core samples needed in clinical trials of malignancy. Conclusions The sequential use of TBNA and ca-TBFB appears to be safe. The larger samples obtained from ca-TBFB increased its sensitivity to detect granulomatous disease and provided specimens for clinical trials of malignancy when needle biopsies were insufficient. For thoracic surgeons and advanced bronchoscopists, we advocate ca-TBFB as an alternative to TBNA in select clinical scenarios.
Infection of the pleural space is an ancient and common clinical problem, the incidence which is on the rise. Advances in therapy now present clinicians of varying disciplines with an array of therapeutic options ranging from thoracentesis and chest tube drainage (with or without intrapleural fibrinolytic therapies) to video-assisted thoracic surgery (VATS) or thoracotomy. A framework is provided to guide decision making, which involves weighing multiple factors (clinical history and presentation, imaging characteristics, comorbidities); multidisciplinary collaboration and active management are needed as the clinical course over a few days determines subsequent refinement. The initial choice of antibiotics depends on whether the empyema is community-acquired or nosocomial, and clinicians must recognize that culture results often do not reflect the full disease process. Antibiotics alone are rarely successful and can be justified only in specific circumstances. Early drainage with or without intrapleural fibrinolytics is usually required. This is successful in most patients; however, when surgical decortication is needed, clear benefit and low physiologic impact are more likely with early intervention, expeditious escalation of interventions, and care at a center experienced with VATS.
Background: Pleural effusions may be aspirated manually or via vacuum during thoracentesis. This study compares the safety, pain level, and time involved in these techniques. Methods: We randomized 100 patients receiving ultrasound-guided unilateral thoracentesis in an academic medical center from December 2015 through September 2017 to either vacuum or manual drainage. Without using pleural manometry, the effusion was drained completely or until the development of refractory symptoms. Measurements included self-reported pain before and during the procedure (from 0 to 10), time for completion of drainage, and volume removed. Primary outcomes were rates of all-cause complications and of early termination of the procedure with secondary outcomes of change in pain score, drainage time, volume removed, and inverse rate of removal. Results: Patient characteristics in the manual (n=49) and vacuum (n=51) groups were similar. Rate of all-cause complications was higher in the vacuum group (5 vs. 0; P=0.03): pneumothorax (n=3), surgically treated hemothorax with subsequent death (n=1) and reexpansion pulmonary edema causing respiratory failure (n=1), as was rate of early termination (8 vs. 1; P=0.018). The vacuum group exhibited greater pain during drainage (P<0.05), shorter drainage time (P<0.01), no association with volume removed (P>0.05), and lower inverse rate of removal (P≤0.01). Conclusion: Despite requiring less time, vacuum aspiration during thoracentesis was associated with higher rates of complication and of early termination of the procedure and greater pain. Although larger studies are needed, this pilot study suggests that manual aspiration provides greater safety and patient comfort.
