| Abstract |
Purpose
: Although the diagnosis of foreign bodies in the airway can be made early, retained and neglected foreign bodies are a common occurrence. The objective of this study was to characterize the clinical features of children diagnosed beyond 14 days following inhalation of a foreign body, long-standing foreign body in airway(LFB).
Methods
: We reviewed the records of 180 cases of airway foreign body, noting the age, symptoms and signs, types and location of foreign body, chest radiographs, and lung perfusion scan findings, and compared these findings of children diagnosed within 14 day(short-term foreign body in airway : SFB, n=130) with those of LFB(n=50).
Results
: Of chief complaints on admission, sputum was more frequent in LFB(24.0%) than in SFB(6.9%). The age distribution was similar, but the proportion of patients aged 3 to 6 years was higher in LFB(16.0%) compared with SFB(3.9%). Of the types of foreign body, plastic was more common in LFB. Abnormal chest radiographic findings were more frequent in LFB(94.0%) than in SFB(80.6%), while the location within the bronchial tree was similar. Hypoperfusion on lung scan was noted in all patients except one in LFB(93.8%).
Conclusion
: There was some difference in age distribution, sputum production, type of foreign body, and abnormal radiographic and perfusion scan findings between SFB and LFB. This suggests that retained foreign bodies may present atypical clinical manifestation and physicians should be alert to the possibility of airway foreign body in children with chronic respiratory symptoms or signs. |
