RESUMEN
Rapid on- site evaluation (ROSE) had gradually become an essential tool in interventional section, especially in pulmonary diseases. People were no longer limited to routine endoscopic operation. ROSE combined with fine-needle aspiration (FNA) enhanced the diagnostic efficiency and diagnostic accuracy of routine bronchoscopes, endobronchial ultrasound- guided transbronchial needle aspiration (EBUS-TBNA) and percutaneous lung biopsy. ROSE can read out the specimen on site , give preliminary diagnosis, and provide help for next operation. The ROSE included cytological ROSE (C-ROSE) and microbiological ROSE (M-ROSE). Now in clinic, C-ROSE was used more broadly. C-ROSE expanded the check range of routine endoscopic operation, and it had been proven to be safe and useful tools.
RESUMEN
Objective To investigate the feasibility and primary therapeutic effect of Dumon Y-shaped airway stent for complex airway disease (stenosis or fistula). Methods Seven patients with complex airway disease underwent placement of Dumon Y-shaped airway stent via rigid bronchoscope, and selected stent depend on carefully measuring the diameter and length of the stenosis or fistula. We retrospectively analyzed the therapeutic efficacy of the patients placed Dumon Y-shaped airway stent. Results All the Dumon Y-shaped airway stent placed successfully. The diameter of the narrowest tracheal stenosis under the carina was improved significantly from (8.03 ± 5.45) mm to (13.08 ± 3.41) mm after the operation. Medical Research Council dyspnea grade improved significantly from Ⅲ~Ⅳ to Ⅰ~Ⅱ and the oxygen saturation improved significantly from (93.86 ± 1.07) % to (98.14 ± 1.07) %. There is no treatment-related complication and death in the seven patients. Conclusion As a new choice, the technique of Dumon Y-shaped airway stent is feasible and safety for the complex airway disease (stenosis or fistula), and worthy of widely promoting.
RESUMEN
Objective To investigate the feasibility and therapeutic efficacy of inverted Y-shaped silicone airway stent for complex airway diseases (stenosis or fistula). Methods According to the particular anatomic structure and the pathological changes of complex airway diseases, the inverted Y-shaped silicone airway stents were designed. 7 stents were implanted in 7 cases of airway complex diseases with the guidance of interventional rigid bronchoscope under general anesthesia. Results The Y-shaped silicone stents were placed successfully followed with the result of immediate relieves of the symptoms. Dyspnea grade was improved significantly from Ⅲ~Ⅳ to 0 ~Ⅱ , and oxygen saturation elevated from ( 84.1 ± 4.5 ) % in inspiring high concentration oxygen to ( 94.1 ± 2.9 ) % in breathing ambient air (P = 0.000). The main complications were cough, foreign body sensation, chest pain, granulation, sputum retention, et al. Conclusion Placement of Y-shaped silicone airway stent is a feasible and safe treatment for complex airway disease, the recent curative effect is reliable, it is worth further promoting.
