目的探讨螺旋CT虚拟内诊镜(CTVE)在小儿气管、支气管异物诊断上的应用价值。方法回顾性分析东南大学医学院附属徐州医院1998年1月至2004年12月收治的121例术前经CTVE诊断为气管支气管异物,并行支气管镜探查术患儿的诊疗情况,并分析CTVE诊断在临床应用上的意义及诊断的阳性符合率。结果121例经CTVE诊断并行支气管镜探查证实并取除异物者115例,诊断符合率95.04%。结论CTVE检查是目前无创非侵入性诊断小儿气管支气管异物的较理想方法。

Application of helical CT virtual endoscopy to the diagnosis of foreign bodies in the trachea and bronchi of children

Objective To probe into the value of helical CT virtual endoscopy in the diagnosis of foreign bodies in the trachea and bronchi of children.Methods From Jan.1998 to Dec.2004,121 patients with foreign bodies in the trachea and bronchi confirmed by helical CT virtual endoscopy were extracted by fibreoptic bronchoscope.The data of all cases were retrospectively analyzed,especially the value of helical CT virtual endoscopy in the diagnosis,and false positive and false negative result were studied.Results Among 121 cases with foreign bodies in the trachea and bronchi confirmed by helical CT virtual endoscopy,there were 115 cases in which foreign bodies were found and extracted by fibreoptic bronchoscope.Compared with helical CT virtual endoscopy,the rate of conformed diagnosis was 95.04%.Conclusion Helical CT virtual endoscopy is the most ideal invasive method in the diagnosis of foreign bodies at present.
