【摘要】 [目的]探讨CT在食管异物X线等常规检查未能检出或不能明确诊断情况下的再检作用。[方法]2007年12月至2011年12月来笔者医院就诊的疑似食管异物77例患者中,取行X线平片诊断6例、钡棉检查诊断23例,共29例为本研究病例,将其检查结果与CT结果和食管镜、手术等临床治疗结果作比对。[结果]X线平片诊断5例食管异物,1例可疑,可疑病例被食管镜排除有异物;食管吞钡挂棉检查有23例诊断有阳性异物,其中4例最后经食管镜排除有异物;29例CT检查24例有食管异物,其余5例CT显示为阴性,经过随访排除食管异物的可能,CT未有假阳性及假阴性结果,CT检查结果均与食管镜或手术结果吻合。检出率比较:X线平片为(83.33%)、钡棉检查为(82.61%)、CT检查为(100.00%),CT较X线平片、钡棉检查检出率高,有统计学意义(P<0.05)。此外,以上影像检查比较,CT显示清楚(能明确食管异物的位置、异物与食管周围组织的关系)。[结论]CT在食管异物诊断中检出率高并显像清楚,在食管异物X线等常规检查未能检出或显像欠清楚,诊断无法明确的情况下再予CT,有助临床避免漏诊、误诊,提高诊断率。更多还原

【Abstract】 [Objective] To discuss the re-check for those esophagus foreign article can’t be checked or definitely by CT or X-ray.[Method] 77 cases of patients with suspected esophageal foreign body need to be checked by CT within 48 hours.Then,the diagnostic result is compared with the results of the surgery,and esophagoscopy.[Result] The cases were definitely diagnosed as esophageal foreign body by surgery or esophagoscope.CT has proved them all and shown the location of esophageal foreign body and correlation with its periphery.CT scan can not only make sure the existence of foreign body and the shape of that,but also can ascertain the relation of foreign matters and organization surrounded and whether there is a complication or not.[Conclusion] For the high detection rate,CT should be the first selected method to examine esophageal foreign body.更多还原
