Objective: To explore the clinical characteristics, diagnosis and perioperative management of bilateral bronchial foreign bodies in children, Reduce the missed diagnosis, misdiagnosis, increase the curative rate and reduce the complications. Method:The clinical data of 25 cases with bilateral bronchial foreign bodies were retrospectively analyzed, and The clinical features, surgical techniques and principles of diagnosis and treatment were summarized.Results: There was a definite history of foreign body aspiration in 22 of 25 cases , The history of foreign bodies in 3 cases was not clear.All 25 cases had paroxysmal cough and wheezing symptoms, There were 2 cases of dyspnea and purple lips,4 cases of vomiting.Signs included unilateral decreased breath sound(16cases).bilateral symmetry decreased Breath sound (9cases).Twenty-two cases had MDCT (multidetector CT) in which 10 were found to have bilateral bronchi abnormalities,and 12 were found to have unilateral bronchi abnormalities.3 cases had no pre-operative imageology. All operations were performed under general anesthesia by experienced doctors with rigid bronchoscopy, The foreign bodies were well removed and without complications. Conclusion:According to the child foreign body choking in a short period of time after the emergence of cough and asthma, dyspnea progressive aggravation,At auscultation, the decrease of respiratory sound in both lungs to the same degree or different degree and the preliminary diagnosis of bilateral bronchial foreign bodies with imaging examination can be made. Foreign bodies should be removed by bronchoscopy as soon as possible to reduce the incidence of death and complications.
