多层CT在下咽及食管异物中的诊断价值

Value of multi-slice CT in diagnosis of hypopharyngeal and esophageal foreign bodies

目的探讨多层CT在下咽及食管异物中的应用和价值。方法回顾分析26例经内镜、手术证实的下咽及食管异物患者的资料,所有患者均行多层CT平扫,分析异物的大小、形态、位置,并观察下咽及食管损伤情况及有无穿孔等并发症。结果多层CT检出异物25例,其中12例可见局部食管壁增厚,3例见异物穿出管壁外,3例有脓肿形成,2例异物游离出食管。1例患者未检出。结论多层CT能直观显示多数异物的大小、形态、位置及有无穿孔等并发症,其在下咽及食管异物诊断中具有重要价值。
