Abstract:
Airway stents provide symptomatic relief in malignant central airway stenosis, but carry the risk of migration, which may result in potentially lethal stent ingestion. A 22-year-old man underwent hybrid stent placement for tracheobronchial stenosis caused by an undiagnosed large mediastinal mass. Within 3 weeks after placement, following initial chemotherapy for provisionally diagnosed B-cell lymphoma, the stent migrated and was ingested. The stent was successfully retrieved endoscopically. This is the first reported case of hybrid tracheal stent ingestion. Early surveillance is warranted in patients with anticipated tumour regression.
