| 摘 要： | 目的探讨CT图像在气管支气管异物性质鉴别中的价值。方法收集2014年8月~2019年4月诊断为气管支气管异物的患者69例，并将其根据异物种类分为花生组（n=36）与非花生组（n=33）。花生组男25例，女11例；非花生组男21例，女12例。分析两组间在临床（异物呛咳史、年龄、性别及居住地），纤维支气管镜下（异物部位、肉芽形成），胸部CT图像上（异物CT值、异物边界清晰度、支气管闭塞、异物长径、异物宽径、肺气肿、支气管狭窄、肺炎、纵隔偏移、纵隔气肿、肺不张及支气管扩张）的特征差异。结果花生组的异物呛咳史较非花生组多见，两组间的异物呛咳史差异有统计学意义（P=0.044）；两组年龄、性别、居住地差异无统计学意义（P>0.05）；纤维支气管镜下，两组间的异物部位（P=0.361）和肉芽形成（P=0.543）差异均无统计学意义；胸部CT图像下，花生组CT值较非花生组低（P < 0.001），异物边界更模糊（P=0.005），支气管闭塞（P < 0.001）更多见，其余CT图像上的特征差异均无统计学意义（P>0.05）。结论结合临床异物呛咳史，胸部CT图像可鉴别气管支气管异物的性质。

| Abstract: | ObjectiveTo explore the value of CT images in identifying the properties of tracheobronchial foreign bodies.MethodsSixty-nine patients with tracheobronchial foreign bodies diagnosed from August 2014 to April 2019 were collected. The patients were divided into peanut group(n=36) and non-peanut group (n=33) according to the type of foreign bodies. Peanut group includes 25 males and 11 females. The differences of clinical characteristics (the history of foreign body aspiration, age, gender and place of residence), features of fiberoptic bronchoscope (location of foreign bodies, granulation formation) and chest CT images(CT value, boundary definition of foreign bodies, bronchial occlusion, length and width of foreign bodies, emphysema, bronchoconstriction, pneumonia, mediastinal displacement, mediastinal emphysema, atelectasis, and bronchiectasis) between the two groups were compared.ResultsFor clinical characteristics, the history of foreign body aspiration in the peanut group was more common than that in the non-peanut group. The difference of the history of foreign body aspiration between the two groups was significant(P=0.044). The age, sex and place of residence were not found significant differences between both groups (P>0.05). For the fiberoptic bronchoscope, the differences of the location of foreign bodies (P=0.361) and granuloma formation (P=0.543) between the two groups were not significant. For the chest CT images, the CT value of the peanut group was lower than that of the non-peanut group (P < 0.001). The boundary of foreign bodies in the peanut group was more blurred than that in the non-peanut group (P=0.005). The bronchial occlusion was more common in the peanut group than that in the non-peanut group (P < 0.001). There were no significant differences in other features (P>0.05) on CT images.ConclusionCombined with the clinical history of foreign body aspiration, chest CT images can identify the properties of tracheobronchial foreign bodies. |
