Abstract

PURPOSE:  To assess the usefulness and safety of silicone stents placement and to compare those between widely used Dumon stents and newly designed Natural silicone stents in the management of tracheobronchial stenosis due to tuberculosis.

METHODS:  The medical records of 69 patients (31 Dumon and 38 Natural) requiring the placement of 75 silicone stents (35 Dumon and 40 Natural) for airway stenosis due to tracheobronchial tuberculosis were reviewed and analyzed.

RESULTS:  Ballooning was the leading method of dilation before stenting (90%). Immediate and lasting relief of dyspnea or improvement of FEV1 was no difference between the Dumon and the Natural group. In both treatment groups, an equal proportion of patients (58% of the Dumon group and 61% of the Natural group) had successful stent removal with median 18 months vs 13 months of stent in situ, orderly. During follow-up, the occurrence of stent-related complications such as migration (39% vs 63%), granuloma formation (42% vs 58%), mucostasis (19% vs 18%) and restenosis (48% vs 37%) were not significant different between the Dumon and the Natural group, respectively. Natural stents and Dumon stents were equally easily inserted and removed. During follow up for median 32months, clinical outcome was stationary in all patients.Conclusion: The silicone stents replacement should be considered in treating tracheobronchial stenosis due to tuberculosis. Both of Dumon and Natural silicone stents seemed to be appropriate, since the efficacy and safety of Natural stent proved to be similar to those of Dumon stent in the management of airway stenosis due to tracheobronchial tuberculosis.

CONCLUSION:  Both of Dumon and Natural silicone stents seemed to be appropriate, since the efficacy and safety of Natural stent proved to be similar to those of Dumon stent in the management of airway stenosis due to tracheobronchial tuberculosis.

CLINICAL IMPLICATIONS:  The silicone stents replacement should be considered in treating tracheobronchial stenosis due to tuberculosis.
