気管支異物症例の検討

Abstract

The aspiration of foreign bodies into the bronchus frequently occurs in children as well as in elderly people. Foreign bodies in the airway not only cause chronic cough and pneumonia, but also result in life-threatening conditions, such as dyspnea and cyanosis. This report presents the clinical characteristics of 6 patients with bronchial foreign bodies who were treated between 2006 and 2010, including 4 male and 2 female patients. The age of the patients ranged from 8 to 83 years old. Foreign bodies were located in the right bronchial tree in all the patients. Chest X-rays showed pneumonia or atelectasis in 5 out of 6 patients. The foreign bodies were an artificial teeth or a tooth in 5 patients, and a fish bone in 1 patient. Five patients had fiberoptic bronchoscopy under local anesthesia, although an 8-year-old girl required general anesthesia with a laryngeal mask. Surgery was needed in only one case. Bronchial foreign bodies present a large range of symptoms, from trivial symptoms to irreversible damage to the bronchus and the lung, which can be life threatening. Nonspecific respiratory symptoms may be mistakenly attributed to other medical diagnoses unless there is a clear history of aspiration. However, an early diagnosis is very important, because inflammatory granulation due to long-term impaction of foreign bodies makes its removal difficult.
