Abstract

Bronchoscopic cryotherapy has been considered as one of the optional interventions for unresectable malignant central airway obstruction (CAO). And it provides high safety and effectiveness in airway patency re-establishment. This report describes the interventional bronchoscopic cryotherapy for a patient with CAO caused by squamous cell carcinoma of the esophagus. We display a series of dramatic change of chest radiographs before and after the intervention. A 70-year-old man with squamous cell carcinoma of the middle third of the esophagus (initial staging, pT2N0M0; stage IIB; in January 2017) underwent Video-assisted esophagectomy and reconstruction with a gastric conduit via a substernal route. Following Chest computed tomography and positron emission tomography revealed disease progression with paratracheal metastases. Progressive dyspnea and chest pain lasted for a month, and he was admitted to the ER. Blood gas analysis revealed type I respiratory failure (pH, 7.445; PaO2, 69.4 mmHg; PaCO2, 40.6 mmHg). Other laboratory data were grossly normal. Chest radiography revealed a total left lung collapse. Chest CT identified a tumor blocking the left mainstem bronchus with the consolidation of the left lung. Dexamethasone and ep...Continue Reading
