ObjectiveTracheobronchial foreign bodies (TFBs) aspiration is rare in adults,although it can occur at any age. This study aimed to report our experience in airway foreign body removal by flexible bronchoscopy in adult patients of central south China. MethodsA total of 244 patients with TFBs over the age of 14 years were reviewed retrospectively from January 1997 to February 2012. The incidence,risk factors,clinical manifestations,radiological findings,types and locations of TFBs were analyzed. ResultsAmong the 27719 patients,TFBs were found only in 0.88%(244) cases. The prevalence of TFB aspiration increased steadily with age beginning in the fifth decade. The incidence of TFBs was 0.62% among people aged 70 to 80 years. Risk factors such as cerebrovascular diseases and neural degenerative disease were found among 32 (6.6%) patients. Among 153 patients with clear history of foreign body aspiration,135 patients (88.2%) were addicted to the hot pepper. Paroxysmal cough (81.1%) was the most common clinical manifestations of TFBs. Only 12 cases (4.9%) were found with non-opaque foreign bodies by chest X-ray but 106 cases (43.4%) were found with opaque foreign bodies by chest CT. The most common indirect chest imaging findings were recurrent infections and consolidation of the same area.Bone fragments of animals was the most common type in foreign bodies (47.2%). The most common position of foreign bodies was the right bronchial (65.6%). Total foreign bodies of 234 patients (95.9%) had been successfully removed by flexible bronchoscopy. ConclusionAlthough TFBs is rare in adults in south China,but yield by flexible bronchoscopy (0.88%) is much higher than that is reported in western countries (0.32%-0.33%). Addiction to the hot pepper and speaking loudly when having dinner may be the major risk factor for high incidence in central south China.
目的 探讨64层螺旋CT最小密度投影（MinIP）结合CT仿真内窥镜（CTVE）对小儿支气管异物的应用价值。 方法 对2010年6月－2012年1月临床拟诊为气管支气管异物的48例患儿行64层螺旋CT检查同期行纤维支气管镜检查，分析64层螺旋CT MinIP结合CTVE等多种重建技术对小儿支气管异物显示情况，并与纤维支气管镜检查结果对照。 结果 MinIP结合CTVE技术诊断气管支气管异物28例，以纤维支气管镜为标准，敏感性93.33%，特异性94.44%，诊断准确率93.76%；两种方法对支气管异物的检出率比较其差异无统计学意义（χ2=0.174，P＞0.05）。 结论 MinIP结合CTVE技术是一种快速无创的检出方法，大大提高了小儿气管支气管异物的敏感性、特异性和检出率，对小儿气管支气管异物纤维支气管镜取出治疗有重要价值。
The specificity of the clinical characteristics and examination results of adult tracheobronchial foreign bodies may not be obvious, which may lead to delay in diagnosis, thereby reducing patients’ quality of life and even life-threatening. However, the current clinicians’ understanding of the disease is still insufficient. Based on the current status of relevant research at home and abroad, this article introduces the medical history collection, clinical features and examination methods (including chest X-ray, chest CT and bronchoscopy), and the treatment and precautions of adult tracheobronchial foreign bodies, and aims to deepen doctors’ understanding of the disease, so as to minimize missed diagnosis and misdiagnosis.
ObjectiveTo highlight the characteristics of bronchial foreign body in Adults. MethodsThe clinical data of three patients with bronchial foreign body were analyzed and related literatures were reviewed. ResultsForeign bodies in three patients were all located in right bronchi. Their initial diagnoses were tumor, pneumonia and foreign body, respectively. They all didn't offer a definite history of foreign body aspiration. Foreign bodies in three patients were diagnosed and treated by bronchoscopy. Through reviewing 978 related literatures, we found 2920 cases of bronchial foreign body in adults. 75.00% of them didn't offer a history of foreign body aspiration. 80.13% of them were misdiagnosed as other diseases before bronchoscopy, such as pneumonia(31.23%), lung cancer(25.21%), tuberculosis(5.81%), bronchiectasis(6.58%) and asthma(12.47%). Some of them were misdiagnosed for over 30 years. ConclusionsBronchial foreign bodies in adults are easily misdiagnosed. Bronchoscopy plays an important role in diagnosis and treatment of bronchial foreign body.
