Active clinical trials for "Lymphadenopathy"

To examine whether EBUS with transbronchial needle aspiration (TBNA) can accurately and safely diagnose enlarged lymph nodes in the chest in patients without suspected malignancy

Participants who are scheduled to have an endo bronchial ultrasound (EBUS) trans bronchial needle aspiration (TBNA) will provide additional samples. These samples will then be sent to Imperial College London to see whether a cell line can be grown. If growth is successful then the samples will be returned to our pathology department to see if grading is possible and then to compare these results with the previous diagnostic samples. The cell line samples will not be used for patient diagnosis.

Endoscopic ultrasound-guided fine-needle aspiration biopsy (EUS-FNA) is a reliable, safe, and effective technique for obtaining samples from the GI wall lesions and from organs adjacent to the GI tract (pancreas, nodes...).Needles available for EUS-FNA include 25G, 22G and 19G. Some studies have suggested that the 25G needle could be equal or even better than the 22G needle. The BXN system and neddles are is a newly developed for EUS-FNA. This trial is developed for testing the accuracy of the new neddle system for EUS-FNA and for comparing the two needles types, 25G and 22G.

A prospective diagnostic clinical study randomising patients undergoing endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) of enlarged mediastinal and hilar lymph nodes to have sampling using the usual EBUS-TBNA needle or a novel biopsy forceps (EBUS-TBNB). The study aims to establish whether the use of EBUS-TBNB can significantly increase the diagnostic yield over EBUS-TBNA, without an increase in complication rates.

Video-assisted thoracic surgery (VATS) is usually performed with general anesthesia and single lung ventilation. However, performing thoracic surgery under awake regional anesthesia has several potential advantages including avoidance of airway trauma and ventilator dependence associated with endotracheal intubation, besides promoting enhanced recovery after surgery and shorter mean hospital stay.

Lymphadenopathy is defined as an abnormality in the size or character of lymph nodes caused by the invasion or propagation of either inflammatory or neoplastic cells into the nodes Accurate lymph node characterization is important for a wide number of clinical situations, including prognosis, prediction, selecting and monitoring treatment, beyond the diagnosis itself (cancer, lymphoma, or inflammatory nodes)

The investigaotors want to establish a real-time and computerized score reporting system based on the significant predictors of the measured sonographic parameters and demographic data.

This is a study of routine neck ultrasound performed by respiratory physicians in patients with mediastinal lymphadenopathy and suspected lung cancer

EUS-FNA is the recommended diagnostic examination of choice when patients present with suspected lower mediastinal lymph nodes on imaging. EUS-FNA is minimal invasive and low in costs, and although it has a good record in detecting diseases (eg confirm a nodal metastasis or granulomas) it has limitations in excluding diseases (missing metastases/ or granulomas) resulting in a false negative rate of 15-20%. Substantial limitations that most likely can be attributed to areas within the node that are not sampled during EUS-FNA tissue acquisition. Improved needle based EBUS/ EUS guided nodal diagnostics might result in improved quality of the fine needle aspirations, reduce in surgical diagnostic procedures , reduced costs and result in a shorter timebefore-treatment interval.

The study is aimed at verifying if a pulmonologist in training can reliably assess the adequacy of EBUS-TBNA samples from intrathoracic lymphadenopathy after a period of training provided by an experienced pathologist.
