RationalThe bronchoscope is a preferential method used to remove airway foreign bodies, but for those located in the distal lumen of bronchus with long-time retention, how to remove them remains an intractable problem.Patient ConcernsA 57-year-old male presented with 2-week history of intermittent hemoptysis. Chest CT upon admission revealed a high-density opacity incarcerated in the distal basal segment of the left lower lobe, along with obstructive pneumonia.DiagnosesThe patient was diagnosed as foreign body aspiration.InterventionsWe firstly used a manual navigating method to draw a bronchoscopic map according to the thin-section CT. Then we adopted ultrathin bronchoscope (UTB) to remove the peripherally located foreign body.OutcomesUTB successfully found the foreign body incarcerated in LB10ciiβ under the guidance of manual navigation, but it was too tender to be extracted completely by forceps, and it was even pushed further away. Then 1.1 mm ultrathin cryoprobe was used, with an activation time of 4 seconds, the chili was frozen and completely removed.LessonsThis first combined application of manual navigating method, UTB and ultrathin cryoprobe, successfully extracted foreign bodies lodged in the distal airways and thus avoided thoracic surgery.Copyright © 2022 the Author(s).
