Abstract

Objective: Foreign body aspiration is a life-threatening emergency for children. Fried chicken is commonly available all over the world, but no cases have previously been reported addressing this food as a tracheobronchial foreign body. We report an extremely rare case of tracheobronchial aspiration of fried chicken complicated by severe bronchitis and postoperative atelectasis. To clarify predisposing factors related to bronchopulmonary complications, we also reviewed paediatric cases of tracheobronchial foreign bodies treated in our department over the past 14 years. Methods: We retrospectively reviewed a total of 77 cases of tracheobronchial foreign bodies from 1988 to 2011. The main outcome measure was duration of hospitalisation, reflecting postoperative therapy. Logistic regression analyses were conducted to determine risk factors for longer hospitalisation. Results: Age, sex, and interval between the aspiration episode and bronchoscopy were not significantly associated with longer hospitalisation. Regarding kinds of foreign bodies, higher rates of longer hospitalisation were noted for patients who had aspirated peanut or animal material, as compared to patients who had aspirated non-organic material (odds ratio, 5.80; 95% confidence interval, 1.12-30.43). Conclusions: In terms of predicting the risk of pulmonary complications, the type of foreign body aspirated offers a more meaningful factor than the interval between aspiration and operation. Specifically, peanuts or animal material containing oils appear to be associated with a more prolonged pulmonary recovery even after retrieval of the foreign body.
