Methods A total of 64 patients, who underwent tracheobronchial metallic stent removal, were included in this case-control study. The patients were divided into two groups: ≤3 types of stent removal methods(n=40)and >3 types of stent removal methods(n=24). The study aimed to compare the demographic characteristics, type of tracheobronchial metallic stents, duration of stent retention, stent-related complications, and other relevant factors between the two groups. Results There were 40 patients, who underwent at most three types of stent removal methods. Meanwhile, there were 24 patients, who underwent more than three types of stent removal methods. No significant statistical differences were observed between the two groups in terms of gender, age, etiology of stent implantation, duration of stent retention, and structural integrity of the stent. There were statistically significant differences between the two groups in terms of the coverage of the stent, stent migration, the stent-related granulation tissue or tumor tissue formation score, and the stent-related cicatricial tissue score. Based on the multivariate analysis, the stent-related cicatricial tissue score(OR=1.354, 95%CI:1.100-1.667, P=0.004)significantly influenced the number of tracheobronchial metallic stent removal methods. Conclusion In this study, the stent-related cicatricial tissue score significantly influenced the number of tracheobronchial metallic stent removal methods, and is the positive correlation relationship.
