Pen Cap Aspirations: Maneuvering for Successful Extraction

Area of Science:

• Pediatric Pulmonology
• Interventional Pulmonology

Background:

• Foreign body aspiration is a common cause of airway obstruction in children.
• Pen cap aspiration presents unique challenges due to its shape and tendency to lodge in the bronchi.

Purpose of the Study:

• To evaluate the efficacy of bronchoscopic extraction for pen cap aspirations.
• To identify factors contributing to successful removal and to refine the technique.

Main Methods:

• Retrospective analysis of 8 cases of pen cap aspiration treated between 2000 and 2014.
• Review of bronchoscopic procedures, patient demographics, foreign body location, and extraction techniques.

Main Results:

• Bronchoscopic extraction was successful in 7 out of 8 pediatric patients (all males, aged 5-11 years).
• A specific technique involving 90-degree rotation of optical forceps to align the pen cap with vocal cords was highly effective.
• One patient required thoracotomy and bronchotomy for removal.

Conclusions:

• Pen cap aspiration is a significant risk in school-aged children.
• The described bronchoscopic technique enhances successful foreign body removal, potentially preventing the need for more invasive surgical procedures like tracheostomy or thoracotomy.
