Objective:To summarize the diagnosis and treatment of pediatric tracheobronchial foreign body

and to reduce its complication and mortality.Methods:Retrospective analysis was carried out among the clinical data of the diagnosis and treatment of 721 cases of tracheobronchial foreign body from 1997 to 2007 in our hospital.Results:In 721 patients

471(65.3%)were males and the other(34.7%) were females.35 patients in critical condition underwent directly bronchoscopy.686 patients had undergone chest roentgenoscopy and X-ray film or CT scanning.721 cases of tracheobranchial foreign body were identified

with 66 cases in the trachea or both bronchus

371 cases in right main bronchus

and 284 cases in left main bronchus.There had been pulmonary closure in 42 cases

11 of which with consolidation of lung were healed by endotracheal irrigation

3 of which with bronchiectasis were not improved after the removed of the foreign body by conservative treatment and bad lobes of lung had to resected.2 patients died of respiratory and circulatory failure.Fist time brochoscopy and removed of foreign body were achieved in 716 cases(99.3%)

which second time were brochoscopy and removed of foreign body was 3 cases.Most of the foreign bodies were peanut

melon seeds and beans.Conclusions Pediatric tracheobronchial foreign body was rapidly diagnosed and treated.The delay of pathogenetic condition can be avoided and the incidence of complication and mortality cut down effectively.
