- Abstract: BACKGROUND: The clinical results of a Natural stent in patients with a benign tracheobronchial stenosis were examined by comparing the clinical outcomes and complications of those patients who underwent Dumon and Natural stenting in the management of benign airway stenosis. METHODS: The medical records of 94 patients (39 Dumon and 55 Natural stent) with a benign tracheobronchial stenosis were reviewed and analyzed. RESULTS: Post-tuberculous stenosis was the leading indication for airway stenting (74%), which was followed by post-intubation stenosis (21%). After intervention, the dyspnea had improved among those patients who underwent Dumon (90%) and Natural (86%) stenting. After stabilizing the dyspnea, the stent could be successfully removed in half of the patients who underwent both Dumon (54%) and Natural (49%) stenting. During the 42 month follow-up period, the complication rate was similar in those patients who underwent Dumon and Natural stenting: migration (46% vs 53%), granulation tissue formation (36% vs 49%), mucostasis (21% vs 16%) and restenosis (51% vs 36%). CONCLUSION: The clinical results of Natural airway stent was similar to those of Dumon stent in the management of benign tracheobronchial stenosis.
