Background: Tracheal strictures are known to recur after dilatation, so they need stenting to prevent recurrence. The objective was to study role of air way stenting (Duman- silica stent) in benign stricture trachea management.
Methods: A hospital based prospective study was carried out among 15 cases (as these cases are very rare, author could study only 15 cases) presented with various clinical features suggestive of tracheal strictures. They were examined and managed by putting tracheal stent for up to eight months period. All cases were followed at regular intervals till 14months after the stent was placed. The outcome was studied.
Results: The tracheal strictures have been found to be more in the age group of 25-30 years. The male to female ratio was 4:1 i.e. for everyone female case there were four male cases. Thus, the tracheal strictures have been more common among the males compared to the females. All of the patients presented with severe stridor, breathing difficulty, and poor exercise tolerance. Most common cause of tracheal stricture was prolonged mechanical ventilatory support >8 days due to organo phosphorus poisoning in past 3months and all of them were males. All cases had good outcome at the end of 14months of follow up. All cases had normal findings. No one developed foreign body reaction, nor did no one develop granuloma formation at the stent site. After stent removal flexible bronchoscopy repeated after 3rd month and 6th month.
Conclusions: Tracheal stenting is very useful procedure in the management of air way strictures.
