Foreign body aspiration with iatrogenic right bronchus perforation - A case report and literature review.

INTRODUCTION AND IMPORTANCE: Evacuation of obstructed trachea foreign body (FB) can be challenging and may have several life-threatening complications. Iatrogenic tracheobronchial injury (TBI) is a rare and devastating complication which need prompt diagnosis and management.

CASE PRESENTATION: An 11-year-old child was brought to the emergency with a history of cough and chest discomfort for the last 15 days. Chest x-ray and computed tomography (CT) chest were done which showed the presence of a FB in the right main bronchus. After all pre-operative investigations, rigid bronchoscopy and removal of the foreign body under general anesthesia was performed. After several attempts, the foreign body couldn't be removed and there was massive surgical emphysema of the chest. Immediately bilateral chest tube was inserted. A repeat CT chest was done which revealed a ruptured of the right main bronchus with migration of the foreign body to the right pleural cavity. Right thoracotomy was performed under general anesthesia. The foreign body was removed and the bronchus ruptured was repaired. The child's vital signs were normal throughout the procedure and she was discharged on the seventh post-operative day.

CLINICAL DISCUSSION: TBI can have devastating scenarios in the absence of quick diagnosis and treatment. Around 80 % of patients with TBI due to accidents have been found to have fatal outcomes before reaching the hospital, probably due to tension pneumothorax, hypoxia, or respiratory failure.

CONCLUSION: Prompt diagnosis and management of complications with definitive repair of the injury were key elements in saving lives after TBI.
