Changes in respiratory track microbial characteristics after airway stent placement

Abstract

Airway stenting is an important clinical intervention applied in patients with airway disorders, but it may change the microbial composition of the airways. Before the placement of stents for benign and malignant airway stenosis, the predominant microbiota in the airway is Staphylococcus aureus, while after stent placement, the microbial spectrum change to gram-negative bacteria. Additionally, there is a close relationship between stent-related infection and granulation tissue growth with Staphylococcus aureus and Pseudomonas aeruginosa.
