ABSTRACT: Inhalation of foreign body in children is a serious accident that may compromise the vital prognosis of the child. The diagnostic was difficult in the absence of a recognizable penetration syndrome. Bronchoscopy is still recommended as the appropriate diagnostic and treatment of foreign bodies. The purpose of this study was to analyze the diagnostic and the treatment result of bronchoscopy and discuss its indications. MATERIEL AND METHODS: A retrospective study analyzing data related to 223 children undergoing bronchoscopy due to suspicion of foreign body aspiration over a period of 10 years (2000-2009). The average age of the children was 29 months (range: one month-13 years). Approximately, two thirds of these patients were boys. The penetration syndrome was reported in 79.8% of cases.
During bronchoscopy, the foreign body was confirmed only in 57.4%. Foreign bodies were found in the bronchus in 79.7% of cases. Among the foreign bodies, 78.1% were of vegetal origin. The average time of stay of the foreign body was of 16.1 days. Penetration syndrome and abnormal physical exam were the most sensitive parameters (79.7% and 82.8%, respectively) but with low specificity (24.2% and 35.8%, respectively). The combination of clinical and radiological signs suggestive of foreign body was the most specific sign (74.7%). Similarly, we found a statistically significant correlation between positive bronchoscopy and simultaneous suggestive clinical and radiological signs (P=0.03). The multivariate study showed that predictors factors of positivity of the bronchoscopy were: abnormal physical exam (P=0.016), abnormal radiological exam (P=0.003) and type of indication (P=0.005).
The diagnosis of laryngotracheobronchial foreign body recures an array of arguments. It is suspected on the clinical interview specially penetration syndrome and on the clinical and radiological presentation. Any suspicion should lead to a bronchoscopy.
