Case ReportsNeedle assembly malfunction: an unusual complication related to endobronchial ultrasound-guided transbronchial needle aspiration.
Endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration has become an invaluable tool for thoracic physicians. Along with medical complications, it is also important to understand the equipment-related malfunctions. ⋯ We report 2 rare cases of Olympus EBUS needle assembly malfunction (model NA-201SX-4021/4022). The first case describes needle breakage and the second case reports the separation of shaft of sheath-sliding mechanism.

Pleural pressure swing and lung expansion after malignant pleural effusion drainage: the benefits of high-temporal resolution pleural manometry.
Malignant pleural effusion is a common complication in end-stage cancer patients and can cause severe dyspnea. Therapeutic thoracentesis is often limited to 1 to 1.5 L. Pleural manometry can be used to recognize a not-expanded lung. ⋯ We demonstrated that a high pleural pressure swing after removal of only 200 mL was related to incomplete lung expansion. We confirmed the association between pleural elastance and lung expansion.

The safety of medical thoracoscopy in a group at high risk for complications.
The use of medical thoracoscopy (MT) for the diagnosis and/or palliative treatment of pleural effusions is expected to become more widespread in the coming years. The aims of the present study were to establish the safety of MT in a group of patients at high risk for complications and to determine the factors that affect the development of complications. ⋯ MT is a safe method for the diagnosis of patients with pleural effusion, even in patients at high risk for complications. However, complications, found in approximately half of the patients, should also be examined in terms of cost.

Endobronchial ultrasound-guided transbronchial needle aspiration in an unselected cohort.
Endobronchial ultrasound (EBUS) with transbronchial needle aspiration (TBNA) is widely used as a diagnostic tool. The aim of this study was to evaluate the sensitivity and diagnostic accuracy of EBUS-TBNA for detecting malignant cells or sarcoidosis in mediastinal, hilar, and lobar lymph nodes. ⋯ EBUS-TBNA is a very sensitive examination in regards to carcinoma in locations accessible from the airways, but it is not suitable for the diagnosis of lymphoma. It also adds pathologic information to make the diagnosis of sarcoidosis.

Diagnostic yield of EBUS-TBNA for the evaluation of centrally located peribronchial pulmonary lesions.
The purpose of this study was to evaluate the diagnostic yield of endobronchial ultrasound with real-time-guided transbronchial needle aspiration (EBUS-TBNA), endobronchial forceps biopsy (EBBx), and 2D fluoroscopic-guided transbronchial forceps biopsy (TBLBx) for centrally located peribronchial lung lesions. ⋯ Where available, EBUS-TBNA of centrally located peribronchial lung lesions should be given a strong consideration given its high diagnostic yield.
