Emergency repair of complete right main bronchial transection after blunt chest trauma: a case report.
Article in International journal of surgery case reports, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Tracheobronchial injury following blunt chest trauma is an uncommon but potentially fatal condition that is frequently underrecognized because of nonspecific early findings. Right main bronchial injuries are particularly important because they often occur near the carina and may present with persistent pneumothorax, pneumomediastinum, extensive subcutaneous emphysema, and failure of lung re-expansion after tube thoracostomy. Case presentation: We report the case of a 16-year-old, previously healthy male who sustained blunt chest trauma after a wall collapsed onto him. He presented with severe respiratory distress, agitation, chest pain, cyanosis, and profound hypoxemia. Chest radiography demonstrated a complete right-sided pneumothorax with a fallen lung sign. Emergency computed tomography confirmed a complete right-sided pneumothorax, marked pneumomediastinum, and a contralateral pulmonary contusion. Despite right-sided chest tube insertion, a massive, continuous air leak persisted, and the right lung failed to re-expand adequately. Case discussion: Emergency right thoracotomy revealed bulging mediastinal pleura and complete transection of the right main bronchus just proximal to its bifurcation. The proximal and distal bronchial stumps were mobilized and repaired using an interrupted end-to-end bronchial anastomosis, followed by pleural flap reinforcement. Intraoperative air-leak testing was negative, and complete right lung re-expansion was achieved. This case highlights the classic but often overlooked diagnostic clues of major tracheobronchial injury and supports early lung-preserving repair when viable tissue is present. Conclusion: Complete right main bronchial transection should be suspected following blunt chest trauma when a pneumothorax is associated with pneumomediastinum, a massive, persistent air leak, and failure of lung re-expansion after tube thoracostomy. Prompt recognition and emergency primary repair can restore airway continuity, preserve the lung, and result in satisfactory clinical respiratory recovery.
