Area of Science:

  • Pulmonology
  • Interventional Bronchoscopy
  • Oncology

Background:

  • Airway obstruction, whether benign or malignant, causes significant distress.
  • Intraluminal stenting is a recognized safe and effective palliative treatment.

Purpose of the Study:

  • To review the experience with airway stenting in Hong Kong.
  • To evaluate the safety and efficacy of silicone stents in managing airway stenosis.

Main Methods:

  • A retrospective review of 33 silicone stent placements in 23 patients over 19 months.
  • Analysis of stent locations, patient demographics, and etiologies of airway obstruction.

Main Results:

  • No procedural mortality; 17% stent migration rate requiring adjustment.

  • Significant symptom improvement in all patients, as measured by visual analogue scale.
  • Common indications included esophageal and bronchial carcinoma, and benign strictures (e.g., tuberculosis).

    • Conclusions:

    • Airway stenting is a safe and effective intervention for selected patients with critical airway stenosis.
    • The prevalence of esophageal carcinoma and tuberculosis in Hong Kong influences patient selection.
    • Operators, patients, and families must be aware of potential complications.
