Implication

Cohort study reveals higher symptom relief but increased complications with self-expandable metallic stents in benign airway obstruction, indicating differences driven by follow-up and disease nature.

Key Points

Evaluate the clinical outcomes, symptom relief, and long-term complication profiles of self-expandable metallic stents (SEMSs) in patients with benign versus malignant central airway obstruction.
Retrospective cohort study of N=149 patients (72 benign, 77 malignant tracheobronchial disease) who received 211 Ultraflex SEMSs (116 benign, 95 malignant) at a tertiary hospital.
Evaluated patient demographics, baseline spirometry (FEV1), symptom resolution, and post-implantation complications across median follow-up times of 429 days (benign) versus 57 days (malignant).
Patients with benign conditions experienced significantly greater symptom improvement following stent placement than those with malignant conditions (76.7% vs. 51.6%; p < 0.0001).
Overall complication rates were significantly higher in benign cases compared to malignant cases (42.2% vs. 21.1%; p = 0.001).
Interventional management was successful for 100% of stent migrations, 81.25% of granulation tissue formations, and 85% of stent fractures.
