64层螺旋CT对食管异物的诊断价值

Diagnostic value of 64-slices spiral CT scanning in esophageal foreign body

目的评价64层螺旋CT对食管异物的诊断价值。方法回顾性分析37例食道异物的64层螺旋CT资料;全部病例均经内窥镜或手术证实。结果 37例食道异物位于颈段30例,胸段7例。其中CT检出35例(鱼刺20例,禽畜类碎骨13例,硬币1例,肉团1例),漏诊2例;另外,CT还发现8例(鱼刺7例、禽类碎骨1例)食管壁肿胀及周围渗出,其中2例伴咽食管右后壁脓肿。结论 64层螺旋CT能清晰地显示食管异物的大小、形态、位置、周围关系及有无并发症,且检查安全、便捷、无痛苦,可作为食管异物最有效的检查手段之一。

Objective To evaluate the diagnostic value of 64-slices spiral CT scanning in the esophageal foreign body.Methods 37 cases with esophageal foreign body,confirmed by endoscopy and surgical operation,underwent 64-slices spiral CT scan and retro-analyzed statistically.Results 30 cases with esophageal foreign body was located at cervical esophagus,7 cases at thoracic esophagus.35 cases with esophageal foreign body in 37 were discovered by 64-slices spiral CT scan,include 20 cases with fishbone;13 bird and animal bone;1 coin;1 meatball,the other was undiscovered.Swelling and exude of esophageal wall in 7 cases with fishbone and 1 case with bird bone,in which,2 cases accompanied by abscess at right-rear esophageal wall.Conclusion The 64-slices spiral CT scan can show the size,shape,location of esophageal foreign body and its periphery and complications,and has an important value for clinical treatment and effect judgement,with the safety,convenience and no-pain,and is one of the most effective method to examine esophageal foreign body.
