The Clinical and Subclinical Features of Patients with Airway Foreign Body at the Endoscopy Department, National Otorhinolaryngology Hospital of Vietnam from 08/2018 to 02/2020

This study describes clinical and subclinical features of 30 patients with airway foreign body at the Endoscopy Department, National Otorhinolaryngology Hospital of Vietnam from August 2018 to February 2020. The study results show that airway foreign body was commonly found in patients aged over 18 (43.33%); male-female ratio was 1.7:1; cough and shortness of breath were two common symptoms with 96.67% and 73.33%, respectively; penetration syndrome was the common clinical symptom with 93.33%; 20% of the airway foreign body cases were detected by X-ray; 100% of the airway foreign body cases were diagnosed by endoscopy; 53.33% of the cases were cured in one day; and 93.33% of the cases showed good treatment results. The study concludes that airway foreign bodies can be detected in all ages with more men than women; penetration syndrome with cough and shortness of breath suggests symptoms of airway foreign bodies; and endoscopy of bronchial airways is the leading method to diagnose and remove airway foreign bodies.
