  • Title: Comparison of natural and Dumon airway stents for the management of benign tracheobronchial stenoses.
    Author: Ryu YJ, Kim H, Yu CM, Choi JC, Kwon YS, Kim J, Suh SW.
    Journal: Respirology; 2006 Nov; 11(6):748-54. PubMed ID: 17052303.
    Abstract:
    OBJECTIVE AND BACKGROUND: To investigate the utility and safety of the 'Natural stent', a newly designed silicone airway stent, the authors compared clinical outcomes and complications in patients who underwent silicone airway stenting for the management of benign airway stenosis. METHODS: The medical records of 94 patients requiring the placement of 100 airway stents (43 Dumon and 57 Natural) were retrospectively reviewed in a tertiary referral hospital. RESULTS: Post-tuberculous stenosis was the leading indication for airway stenting (74%), followed by post-intubation stenosis (21%). After intervention, dyspnoea improved in patients who underwent Dumon (90%) and Natural (86%) stenting. After stabilizing dyspnoea, stents could be successfully removed in half of the patients who underwent Dumon (54%) or Natural (49%) stenting. During a 42-month follow-up period, complication rates were similar in patients who underwent Dumon or Natural stenting. CONCLUSION: Natural airway stent was as effective and safe as Dumon stent for the management of benign tracheobronchial stenoses.
