Clinical Comparison of Airway Stent Placement in Intervention Room and Operating Room / 中国肺癌杂志

BACKGROUND@#Airway stent placement is the effective regimen for central airway obstruction (CAO), while its application scenarios varied. This study aimed to make clinical comparison of airway stent placement in the intervention room and operating room.@*METHODS@#Patients underwent airway stent placement between 2014 and 2018 were included in this retrospective case-control study. Clinical performance of airway stent placement in intervention room and operating room were compared.@*RESULTS@#82 patients were included in this study, including 39 in the intervention room and 43 in the operating room. Patients treated in the intervention room had lower Charlson comorbidity index (CCI) (P=0.018) and received less Y-shaped stents (P<0.001). Better clinical response (P=0.026), more stents placed (P<0.001) and longer length of stent (P<0.001) were observed in operating room, while there was no significantly statistical difference of stent-related complications and post-stent survival rate between the two groups. Extracorporeal membrane oxygenation (ECMO) supported airway stent placement procedures were performed in the operating room, which provided definitive safety support for high-risk intervention.@*CONCLUSIONS@#Patients with CAO could benefit from the operating room scenario, and airway stent placement in the operating room is more suitable for patients with higher CCI scores and receiving more complicated procedures.

Changes and treatment of cough and expectoration in the patients with lung cancer after airway stent placements / 第三军医大学学报

Objective To evaluate the changes and clinic countermeasures of cough and expectoration in the patients with lung cancer after airway stent placements. Methods With the fibrobronchoscope, metal stents were placed in tracheas, main bronchia or right intermediary bronchia. It was compared that the degrees of cough and expectoration difficulties, the volumes and mucin content of sputa and lung functions before the placements, within 3 d and 1 to 2 months after operation. Results Within postoperative 3 days, the patients coughed more frequently, but VC, FEV_(1) and PEF were improved significantly. In postoperative 1 to 2 months, the degrees of cough were close to preoperative degrees, lung functions kept on improved conditions, but expectoration difficulties, volumes and mucin contents of sputa increased markedly, especially in the patients with tectorial membrane stents. Proper stents and reasonable treatment including use of antitussive, apophlegmatisant and antibiotics could decrease the degrees of cough within postoperative 3 days, and expectoration difficulties, volumes and mucin contents of sputa in postoperative 1 to 2 months. Conclusion To the patients with malignant central airway constriction, metal stent placement would improve ventilative functions but bring difficulties for cough and expectoration. The side complications would be relieved through corresponding treatments.
