BackgroundThis study aims to investigate the related factors for the retention time of tracheobronchial foreign bodies in infants and children, to provide help for the assessment of the disease, surgical risk, and prognosis.Materials And MethodsThe clinical data of 1060 patients with tracheobronchial foreign bodies from January 2015 to December 2015 were retrospectively studied, and the correlation of the retention time of foreign bodies with age, gender, preoperative complications, granulation formation, operation time, and hospital stay was analyzed.ResultsThe retention time of foreign bodies was not correlated with age (r = 0.041, P = 0.194) and gender (r = 0.039, P = 0.214) but was correlated with preoperative complications (r = 0.072, P = 0.023), granulation formation (r = 0.134, P < 0.001), operation time (r = 0.112, P < 0.001), and hospital stay (r = 0.189, P < 0.001).ConclusionsThe retention time of foreign bodies was closely correlated with granulation formation, preoperative complications, operation time, and hospital stay.Copyright © 2018 Elsevier Inc.
