Summary
A pediatric patient with a persistent cough due to a pistachio nut foreign body obstructing the airway was successfully treated with a Nd:YAG laser. This minimally invasive endoscopic approach restored bronchial patency without major surgery.
Area of Science:
- Pediatric Pulmonology
- Laser Endoscopy
- Foreign Body Aspiration
Background:
- Foreign body aspiration is a common cause of airway obstruction in children.
- Persistent airway obstruction can lead to chronic cough and significant morbidity.
- Traditional management may involve invasive thoracic surgery.
Observation:
- A 7-year-old boy presented with an 18-month history of nonproductive cough after a choking episode.
- Bronchoscopy revealed a left mainstem bronchial obstruction caused by granulation tissue.
- An embedded pistachio nut shell was identified as the underlying foreign body.
Findings:
- Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser fiber was advanced through a ventilating bronchoscope.
- The laser effectively vaporized granulation tissue, enabling foreign body retrieval.
- Complete bronchial patency was restored post-retrieval.
Implications:
- Endoscopic Nd:YAG laser treatment offers a precise, minimally invasive option for central airway lesions in children.
- This technique obviates the need for major thoracic surgery in select cases.
- Successful management highlights the utility of laser bronchoscopy for pediatric airway foreign bodies.
