VEGA-BRICENO, Luis Enrique et al. Endoscopic findings in children with recurrent pneumonia. Rev. chil. pediatr. [online]. 2004, vol.75, suppl.1, pp.51-58. ISSN 0370-4106.

Introduction: Recurrent pneumonia (RP) is a respiratory condition which is a regular consult at reference centers. The probable causes involved in its pathogenesis are numerous; however, insufficient data is available on the endoscopic findings in children. Materials and Methods: Retrospective review of all fiberbronchoscopies (FB) carried out in the Hospital Clínico de la Pontificia Universidad Católica between March 1993 and February 2004. Results: A total of 65 children with RP (mean age: 42 months, 52% male) were admitted for endoscopic evaluation (91% unifocal). The most frequent associated basal medical conditions were: Recurrent Bronchial Obstructive Syndrome (27), gastroesophageal reflux (11), immunodeficiencies (10), asthma (8) and neurologic damage (6). Fourteen patients presented more than one endoscopic finding, the most frequent being: Bronchomalacia (36%), supernumerary bronchi (36%), bronchial stenosis (33%) and tracheal bronchus (10%). The findings were more frequent in the right lung (63% vs. 17%), this difference being statistically significant (p < 0,01). Twenty-four children had a completely normal endoscopic evaluation. Regression analysis demonstrated a close relationship between male sex and the presence of an abnormal airway (p = 0,008). Lastly, a relationship could not be established between the number of endoscopic defects and the number or location of pneumonias (p = 0,67 and 0,64, respectively). Conclusions: It is concluded that children with RP, primarily unifocal, present a high incidence of endoscopic findings which may correspond to normal or pathologic anatomic variants based on the clinical manifestations
