Lymphadenopathy
Conditions
Brief summary
Several benign and malignant diseases are associated with hilar and mediastinal lymphadenopathy. Endobronchial elastography that is an imaging procedure used for the visualization of tissue elasticity and Tissue Harmonic Imaging (THI) might be useful for the differentiation of benign and malignant lymph nodes.
Detailed description
Patient enrolment and data acquisition is to be carried out on a prospective basis. Patients with hilar and/or mediastinal lymphadenopathy and indication for EBUS-TBNA are enroled. It is planned to evaluate 100 lymph nodes by elastography and THI. All patients will undergo diagnostic bronchoscopy at one study centre in Heidelberg.
Interventions
Patients with enlarged hilar and/or mediastinal lymph nodes and indication for EBUS-TBNA undergo diagnostic bronchoscopy. For characterisation of the enlarged lymph nodes endobronchial ultrasound with elastography and Tissue Harmonic Imaging (THI) are used. Afterwards, EBUS-TBNA is performed. The results of elastography and THI are correlated with the cytological result obtained by EBUS-TBNA.
