Insights
A child ingested a lithium battery, causing esophageal perforation and mediastinal injury. Rare complications, including tension pneumothorax, arose during retrieval, leading to mediastinitis and a complex recovery.
Area of Science:
- Pediatric Gastroenterology
- Thoracic Surgery
- Emergency Medicine
Background:
- Esophageal perforation is a critical condition often resulting from foreign body ingestion.
- Lithium battery ingestion poses unique risks due to corrosive injury potential.
Observation:
- A pediatric case involving esophageal perforation and mediastinal injury secondary to lithium battery ingestion.
- Complications during endoscopic retrieval included subcutaneous emphysema, tension pneumothorax, and pneumomediastinum due to excessive air insufflation.
Findings:
- The patient developed mediastinitis following the initial injury and iatrogenic complications.
- The case highlights the potential for rare, life-threatening events during foreign body removal procedures.
Implications:
- Emphasizes the need for careful endoscopic techniques and prompt management of airway complications in pediatric foreign body ingestion.
- Highlights the severe consequences of esophageal battery ingestion and the importance of timely intervention.
Abstract:
We present a case of a child with an ingested lithium battery causing esophageal perforation with mediastinal injury extending to the pleural cavity. During the endoscopic retrieval of the battery, the child developed the rare complication of subcutaneous emphysema, tension pneumothorax, and pneumomediastinum from excessive iatrogenic air insufflation. The patient developed mediastinitis and had a complicated postoperative course.

Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
