The aetiology of the aforementioned diseases is not always recognisable. The diagnosis of these dismal diseases is a vivid challenge for the physicians. Through the intervening years different diagnostic algorithms have been implemented towards more accurate outcome. Different types of ILD’s demand diverse diagnostic approaches. In the latest years a novel diagnostic mini invasive approach seems to gain continuously terrain towards the diagnosis of ILD’s. Transbronchial cryobiopsy may be the Holy Grail in the diagnosis of these diseases or a misleading diagnostic tool in this challenging field.展开更多

Convex probe endobronchial ultrasound （CP-EBUS） has allowed for performing real-time transbronchial needle aspiration （TBNA） of enlarged hilar and mediastinal lymph nodes and therefore could also be used as a means of diagnosing proximal peribronchial lesions. Methods： We retrospectively analyzed the results related to 72 patients who underwent CP-EBUS for peribronchial lesions without endobronchial involvement and adjacent to three-grade bronchi based on chest computed tomography （CT） scan. We recorded the images during EBUS as well as the diagnostic results of TBNA and conventional-transbronchial lung biopsy/brush （C-TBLB/b）, and final diagnoses were based on pathologic analysis and follow-up. Results： In all cases, the mass was able to be identified using EBUS in 97.2% patients （70/72） who were performed with EBUS-TBNA ＋ C-TBLB/b. Sixty-six patients had a final diagnosis, 80.0% patients （56/70） had malignancies, and 14.3% patients （10/70） had benign disease. In malignancies, the diagnostic yield of C-TBLB/b was 57.1% （32/56） and in EBUS-TBNA was 85.7% （48/56）, whereas pathologic diagnosis reached 94.6% when EBUS-TBNA was combined with C-TBLB/b. C-TBLB/b ＋ EBUS-TBNA also exhibited stronger potency of histolytic diagnosis for malignancies than either EBUS-TBNA or C-TBLB/b alone. Furthermore, there are data supporting the value of EBUS-TBNA for the diagnosis of benign lung disease. Conclusion： The combined endoscopic approach with EBUS-TBNA and C-TBLB/b is an accurate and effective method for the evaluation of peribronchial lesions, with better results than using each technique alone.展开更多
