Objective: To emphasize the need of an accurate diagnosis of congenital esophageal stenosis due to tracheobronchial remnants, since its treatment differs from other types of congenital narrowing. Case description: Four cases of lower congenital esophageal stenosis due to tracheobronchial remnants, whose definitive diagnosis was made by histopathology. Except for the last case, in which a concom...

UNLABELLED The established endoscopic treatment of web-like tracheobronchial stenosis is laser vaporization, but the appearance on the market of a new cutting mode with a lower coagulation effect has been proposed as an alternative to laser due to less injury to the tissue. OBJECTIVES To study the clinical and functional consequences, as well as the side effects of this technique. Afterwards,...

Silicone tracheobronchial stents are being increasingly used in a large number of patients for the treatment of tracheal stenosis. One very rare complication due to tracheobronchial stenting is bronchoesophageal fistula (BEF), which has been associated with the use of metallic stents. We report intraoperative management of a patient undergoing repair of a BEF, following previous insertion of a ...

Endobronchial tuberculosis refers to tuberculous infection of the tracheobronchial tree. Diagnosis requires a high index of suspicion since symptoms are attributed to co-existing pulmonary tuberculosis and airway lesions are not detectable on chest radiograph. While computed tomography and bronchoscopy are useful for the evaluation of tracheobronchial stenosis or obstruction, goals of treatment...

Double lumen tubes (DLT) are a cornerstone in thoracic anaesthesia to achieve onelung ventilation. Due to the shape and size of these devices, airway injuries might occur. The reported incidence of tracheobronchial ruptures caused by a DLT is very low (0.005% for single-lumen tubes and 0.05% for double-lumen intubations), but the outcome can be life-threatening (1, 2). In the past, treatment of...

We tested the hypothesis that oxidant-injured cells upregulate thioredoxin, whereas oxidant-stressed, but not injured, cells upregulate interleukin (IL)-8 after injury. We exposed primary human tracheobronchial epithelial cells and transformed human bronchial epithelial cells (BEAS-2B S.6) to 0, 200, 400, or 600 microM H(2)O(2) for 1 h followed by an additional 7 h of incubation. Subsequently, ...
