This is a case of a left lower bronchial foreign body in a 11 years old boy. This boy was admitted to E.N.T. clinic, Chonnam University Hospital with the complaints of paroxysmal attack of cough and dyspnea for 45 days. He had been treated at a local clinic under the diagnosis of active pulmonary tuberculosis, however, no significant response was achieved by the treatment. The chest X-ray film showed atelectatic shadow, however, no density of suspicious foreign body was observed. On the clinical points of view and the patient's history, bronchoscopy was carried out under the general anesthesia and a plastic gun bullet was removed from the left main bronchus. The boy was discharged from the hospital with good aeration of the left entire lung field and good recovery.

Purpose : Childhood accidents have been increasing recently. Accidents rank as the leading cause of childhood mortality and morbidity. We performed this study to evaluate the causes of childhood accidents. Methods : The authors analysed retrospectively the medical records of 6,410 cases of childhood accidental injuries who visited the emergency room of Asan Medical Center from January 1990 to December 1999. Results : The most common type of accidents was trauma which accounted for 5,038 cases of the total accidents, followed by falls, burns, foreign body aspiration, and poisoning. The most common age of foreign body aspiration was under two years old and the male to female ratio was 2 to 1. The most common site of foreign body aspiration was the esophagus and the stomach, followed by the respiratory tract. In airways, the right and left main bronchus were the most common site for foreign body aspiration and were accompanied by the highest mortality. The most common foreign body in the gastrointestinal tract and respiratory tract were coins and peanuts, respectively. Conclusion : The most common cause of accidents was trauma, followed by falls, burns, foreign body aspiration, and poisoning. The incidence of foreign body aspiration and poisoning is increasing in infants. In cases of foreign bodies in airways, proper management is needed because of the high mortality rate.

Endobronchial foreign bodies are difficult to diagnose as the cause of obstructive pneumonia and atelectasis, However, once discovered, they can generally be removed, leading to an immediate and dramatic resolution of the symptoms. Occasionally, small foreign bodies that lodge in the peripheral airway are often initially asymptomatic but become symptomatic several years later. We reported a case of obstructive pneumonia and massive hemoptysis caused by a foreign metallic body. The patient knew that the foreign body was lodged in the peripheral airway on the chest X-ray, but did not want treatment. Several years later, he had a massive hemoptysis and obstructive pneumonia. Removal with a flexible bronchoscope failed, but the metallic foreign body was self-expectorated by coughing after the procedure. The pneumonia was resolved after removing the foreign body. The patient improved and was discharged without any sequela.

Background: We wanted to examine the clinical characteristics of adult patients with tracheobronchial foreign bodies (FBs) according to the risk of aspiration and the outcomes of intervention with using a fiberoptic bronchoscope. Methods: From December 1994 through December 2004 at Kyung Hee Medical Center, we retrospectively analyzed the medical records of 29 adult patients with FBs that were identified by using a fiberoptic bronchoscope. Results: 14 patients were not at risk of aspiration, whereas 15 had cerebrovascular diseases and they were at a high risk of aspiration. No history suggestive of FB aspiration was noted in 7 (24.1%) patients. Respiratory symptom(s) were noted in 22 patients, and these symptoms were cough (62.0%), dyspnea (44.8%), fever (20.7%), wheezing (13.8%), chest pain (10.3%) and hemoptysis (0.4%). Only 60% of those patients at a high risk of aspiration had symptom(s) (92.8% of those patients without a risk of aspiration had symptoms, p=0.005). Those patients at risk for aspiration had a longer duration of symptoms (median: 4 days vs. 2 days for those patients not at risk for aspiration, p=0.007) before diagnosis. Acute respiratory symptom(s) within 3 days after aspiration were more frequent in the patients without a risk of aspiration (9 vs. 4, respectively p=0.048). Chest x-ray revealed radiological abnormalities in 23 patients, and these were opacities suspicious of FB (n=11), pneumonia (n=8), air trapping (n=5) and atelectasis (n=3). There were no differences in radiological findings according to the risk of aspiration. FB aspiration developed most commonly during medical procedures (57.1% for the patients at risk) and during eating (35.7% for the patients without risk). The most common FB materials were teeth (n = 11). Alligator jaw biopsy forceps (n = 23) was the most commonly used equipment. All of the FBs were removed without significant complications. Conclusion: This study underlines that a tracheobronchial FB in the patients who are at a high risk of aspiration are more likely to overlooked because of the more gradual onset of symptoms and the symptoms develop iatrogenically in many cases.

The authors have been performed a statistical survey for 228 cases with foreign bodies in the food and air passages who had visited the department of Otolaryngology, National Medical Center and removed endoscopically during the period of last 10 years from 1966 to 1975. The following results were obtained: 1. The total numbers of foreign bodies in the food and the air passages were 228 cases, and among of them 181 cases were foreign bodies in the food passage and 47 cases were foreign bodies in the air passage. The ratio between the food and the air passages was about 3.7 : 1. 2. The prevalent foreign bodies in the esophagus were coin, meat and food particles and bone in order of frequency. In air passage, bean and peanut were most prevalent foreign bodies and the next were metalic substances, fish bone in order of frequency. 3. In the age incidence, 65.4% of the esophageal foreign bodies and 67.6% of foreign bodies in the air passage were under 5 years of age especially coin, 92.9%. 4. In sex distribution, 99 cases were female, and the ratio between male and female was 1.3:1. There was no significant difference between male and female in the foreign bodies of the esophagus but the foreign bodies in the air passage were more prevalent in male as the ratio of 2.1:1. 5. The most prevalent site of lodgement in esophagus was first physiologic narrowing of the esophagus as the count of 83.8%. In foreign bodies of the air passage, bronchial foreign bodies were most frequent. And bronchial foreign bodies were more frequent in the right side as the ratio of 3.7:1. 6. In duration of lodgement, 56.0% of foreign bodies of the food passage were removed within 24 hours and almost of them were removed within 5 days. In foreign bodies in the air passage, only 32.4% were removed within 24 hours but 29.7% were removed within more than 1 week in the air passage. 7. Under the esophagoscope, granulation tissue were noted in the 5 cases of the foreign bodies in the esophagus due to foreign bodies. In foreign bodies of the air passage, complication were encountered in the 4 cases and also removed surgically and among of them, 2 patients were expired due to complications during post operative course.
