Bronchoscopic Management As An Alternative Treatment In Non-Operable Benign Tracheal Stenosis

Background Endoluminal therapy either by dilatation, scar tissue resection or stent insertion is an established treatment for non-malignant airway stenosis although the surgical approach is still considered the "gold standard." No clear consensus exists on the structured role of each modality.Aims We aimed to investigate the role of bronchoscopic management in non-operable tracheal stenosis cases, evaluating the effectiveness and safety of each procedure based on a structured algorithmic approach.Patients and methods This prospective study was carried out on (40) consecutive patients diagnosed between March 2017 and March 2020 with tracheal stenosis not amenable to surgery. All strictures were first evaluated by flexible bronchoscopy and classified as simple or complex. Patients were treated following a standardised therapeutic algorithm approach based on published evidence and our own expertise.Results The mean age of the study population was 45.25 +/- 18.79; lesions were classified as simple (14) and complex (24), while two patients had mixed type stenosis. Long term success rate was 100% in simple stenosis and 87.5% in the complex ones. Stents were deployed in 24 cases, most of which were of the complex type and only two of the simple type. Post-procedural mild to moderate complications were detected overall in 70% of the patients. All complications were non-life threatening, mostly stent-related and were effectively managed.Conclusion We conclude that after accurate classification and a structured algorithmic approach, interventional bronchoscopic management may play a crucial role in the effective treatment of benign tracheal stenosis.
