Endobronchial ultrasound convex probe for lymphoma, sarcoidosis, lung cancer and other thoracic entities. A case series.

Endobronchial ultrasound endoscopy is a state of the art diagnostic endoscopic procedure for the thorax. Firstly it was designed mainly for the staging of lung cancer and of course for the diagnosis of suspicious findings in large central airways. The main limitation of the equipment is the diameter of the instrument and therefore it can only be guided through large airways. However; the diameter of the working channel also provides a large tissue sample nowadays with the 19G biopsy needle. We will provide our experience with the 22G needle of the endobronchial convex-probe in several medical situations of the thorax.
