先天性食管闭锁与食管气管瘘的X线、CT表现

X-ray and CT Findings of Congenital Esophageal Atresia and Tracheoesophageal Fistula

目的探讨先天性食管闭锁与食管气管瘘的X线、CT诊断价值。资料与方法回顾性分析7例先天性食管闭锁与食管气管瘘的影像学表现,7例均行X线平片和食管造影,其中3例进行了CT检查。结果7例中Ⅰ型2例、Ⅱ型1例、Ⅲ型4例(Ⅲa型1例,Ⅲb型3例)。X线胸腹平片显示胃肠积气4例、吸入性肺炎6例及右上肺不张2例;食管造影显示近端呈盲端6例、近端食管气管瘘1例;CT检查显示远端食管气管瘘3例。结论综合应用X线、CT检查对先天性食管闭锁与食管气管瘘的确诊及分型具有重要意义。

Objective To explore the value of X ray and CT in diagnosis of congenital esophageal atresia and tracheoesophageal fistula. Materials and Methods 7 cases of congenital esophageal atresia and tracheoesophageal fistula were evaluated. 7 cases were examined by the plain film and esophagography, 3 cases were examined by CT. Results There were 2 cases of type Ⅰ , 1 cases of type Ⅱ ,4 cases of type Ⅲ. Routine chest and abdominal plain film could show gastric intestinal distension （4 cases）, aspirated pneumonia （ 6 cases） and atelectasis of right upper lobe （ 2 cases ）, Esophagography could show the upper esophageal cecum （6 cases ） , the esophageal cecum and tracheoesophageal fistula were well revealed in CT（3 cases）. Conclusion X ray and CT play an important role in diagnosis and classification of congenital esophageal atresia and tracheoesophageal fistula.
