Management of a Penetrating Gunshot Wound of the Trachea and Bullet Extraction Using Bronchoscopy
Bibliographic record
Abstract
A 34-year-old man presented with a gunshot wound fracturing the medial third of the left clavicle and penetrating the hemithorax. Chest x-ray demonstrated a metallic object suggestive of a bullet at the right hilar level. Computed tomography revealed bilateral subcutaneous emphysema, pneumomediastinum, and mild left pneumothorax. Initial exploration with flexible bronchoscopy revealed a left tracheal wall perforation in the superior third yet, no exiting orifice. The bullet location was confirmed to be at the right lower lobe bronchus. Considering that the diameter of the bullet was greater than that of the endotracheal tube, we extracted the bullet with a rigid bronchoscope. The tracheal repair was performed through a posterolateral thoracotomy. The patient recovered without any further complications. Combined use of flexible as well as rigid bronchoscopes was essential in the management of this patient.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
