[Pneumological aspects of bronchial foreign bodies in children. Experience with 100 cases].

100 cases of bronchial foreign body seen over a period of 4 years represent 1.2% of the admissions of a paediatric pneumology unit; 73% of the children were aged between 6 months and 3 years. The foreign body was vegetable in 61% of cases (a peanut in 44% of cases). The time between the inhalation and the endoscopic diagnosis was greater than 7 days in 70% of cases and greater than 30 days in 37% of cases. Removal of the foreign body was possible in all but one case. In particular, the authors studied the pneumological implications of a foreign body: the value of a quantitative bacteriological study of the bronchial secretions, which was significant in 43% of cases, and detection of the sequelae by prospective clinical and functional surveillance with a follow-up of 3 to 24 months. After 6 months, persistent radiological abnormalities were found in 40% of cases, perfusion disorders were found in 35% and ventilation disorders were found in 64%. A surgical operation was performed in 7 cases: one case of bronchotomy for extraction of the foreign body and 6 cases of parenchymal excision, including 2 total pneumonectomy for a destroyed lung. These were no death. The pathophysiology of the complications of functional disorders and of dilatation of the bronchi is discussed in the context of the experience gained from this series.
