    This article presents a case report of a patient suffering from bullous emphysema and chronic obstructive pulmonary disease, who was diagnosed with tension pneumothorax after undergoing endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). Tension pneumothorax is a severe but rare complication of EBUS-TBNA. It can result from lung injury caused by the biopsy needle or, in patients suffering from bullous emphysema, from spontaneous rupture of an emphysematous bulla resulting from increased pressure in the chest cavity during cough caused by bronchofiberoscope insertion. The authors emphasize that patients should be carefully monitored after the biopsy, and, in the case of complications, provided with treatment immediately in proper hospital conditions. Patients burdened with a high risk of complications should be identified before the procedure and monitored with extreme care after its completion

    Telepathology is an emerging form of diagnostic process introducing digitalization of slides prepared from formalin-fixed paraffin-embedded materials and stained cytological smears. The use of whole slide imaging (WSI) systems could accelerate and improve the diagnosis of malignant neoplasms without the need of on-site pathologist or transporting diagnostic material in-between different locations. The implementation of endobronchial ultrasound (EBUS) and endoscopic ultrasound (EUS) with fine needle aspiration (FNA) in diagnostic process of advanced lung cancer creates a new field for telepathology utilization. In selected patients, pathomorphological and genetic diagnosis may take less than a week and therapeutic decisions can be made in a short time. There are several important issues that concern the use of telepathology and WSI in everyday clinical environment. This short review presents the pros and cons of this technology and its applicability in rapid diagnosis of lung cancer, its utilization in connection with novel sampling methods and molecular analysis.Telepatologia to nowa forma procesu diagnostycznego wprowadzaj─ůca cyfryzacj─Ö preparat├│w przygotowanych z bloczk├│w parafinowych lub wybarwionych rozmaz├│w cytologicznych.

    The aim of the study was to assess the diagnostic yield of transbronchial lung biopsy (TBLB) without fluoroscopicguidanceinperipherallesionsofdiameter2,5-6cm.TBLBwasperformedin65consecutivepatientswithout abnormalities in bronchial tree in standard bronchofiberoscopyandprecededbycomputedtomography(CT). The CT guidance helped to select the segment of lung to be biopsied. In 39 patients (60%) TBLB enabled to diagnose 36 cases of lung cancer, 2 cases of carcinoid and 1 case of malignant lymphoma. There were 26 cases (including 21 cases of lung cancer) undiagnosed by means of TBLB. In 24 patients the diagnosis was established by means of other methods like transbronchial needle aspiration (TBNA) ÔÇô 5 cases, thin needle biopsy (TNB) ÔÇô 12 cases, open lung biopsy (OLB) ÔÇô 7 cases and in the remaining 2 patients a regression of clinical and radiological features was observed. Transbronchial lung biopsy was found to be efficientdiagnosticmethodinperipherallesionshigher than 2,5cm. However, in 40% of cases this technique doesnÔÇÖt allow to establish a diagnosis. This, in turn implicates the necessity for further diagnostic procedures including TBNA, TNB or even OLB

    Transbronchial lung cryobiopsy guided by radial mini-probe endobronchial ultrasound in interstitial lung diseases ÔÇö a multicenter prospective study

    Introduction: Transbronchial lung cryobiopsy (TBLC) is commonly used in diagnosing interstitial lung diseases (ILDs). A┬ágeneral anesthesia with endotracheal intubation, balloon blockers and fluoroscopy control is the most common modality. Simplifying the procedure without decreasing itÔÇÖs safety could result in wider use.Prospective, observational study was conducted in three Polish pulmonology centers to evaluate safety and diagnostic yield of TBLC under conscious sedation, without intubation and bronchial blockers and with radial-EBUS guidance instead of fluoroscopy. Material and methods: In patients suspected of ILD, in accordance with high resolution computer tomography (HRCT) selected lung segments were examined with radial-EBUS mini probe without a┬águide sheath. If the lung infiltrations were visible this locations were preferred. If not, specimens were taken from two different segments of the same lobe. Two to five biopsies with freezing time 5ÔÇô8 seconds were performed. Moreover ultrasound examination was used to avoid injury of lung vessels.Results: From March 2017 to September 2019 ÔÇö 114 patients (M: 59, F: 55) of mean (SD) age 54 (14) years were included to the study on the basis of medical history and HRCT. Histopathology was conclusive in 90 (79%) patients and included 16 different diagnoses (sarcoidosis, EAA, COP predominantly). 24 inconclusive biopsies of unclassifiable pulmonary fibrosis were followed up. Complications included five cases (4.4%) of pneumothorax requiring a┬áchest tube drainage and a┬áminor and moderate bleeding in few cases. There was no need for use of balloon bronchial blockers.Conclusions: TBLC under conscious sedation guided by radial EBUS mini-probe is novel, reasonable and safe technique for histological diagnosis of ILDs
