Silicone stent were implanted in 74%, metallic autoexpandible in 20% and a combination of both in 6%. See table for microbiological results. Wilcoxon test shows that there are significant statistical differences in the prevalence of PPM colonization (25.6% vs 71.8%, p<0.05) and the type of germ (p<0.05) in the first control (34 days of median)Subsequent analysis between consecutive controls doesn't find any statistical difference. The incidence density is 42 cases per 100 person-month (25 new cases during follow-up 59.4 months).View this table:Prevalence of PPM colonization/Type of germConclusions: Tracheobronchial stents are associated with a high, increasing and irreversible colonization of PPM, with a prevalence of 87.5% after 12 months. Incidence density is high. The main colonizing PPM are P. aeruginosa and S. aureus. ER -
