食管壁内气管软骨异位症(附7例报告)

Cartilaginous Tracheobronchial Ectopia in the Esophageal Wall: Report of 7 Cases

目的：探讨食管壁内气管软骨异位症（ＣＴＥ）的诊断依据。材料与方法：１９９１年以来７例ＣＴＥ作钡餐检查，４例于首次检查建立诊断，２例经复查明确诊断。７例均经手术和病理检查证实。结果：食管下段重度向心性恒定狭窄７例；狭窄段下“钟摆样”钡滞留５例；狭窄段食管壁内细管道征２例。结论：ＣＴＥ的Ｘ线改变具有特征性，可作为术前诊断的依据。

Objective: To study the diagnostic criterion of cartilaginous tracheobronchial ectopia (CTE) in the esophageal wall.Materials and Methods:Since 1991, 7 cases of CTE have performed barium meal study. The diagnosis was made in 4 with first exam and in 2 with successive exam. All the 7 cases were confirmed operatively and pathologically.Results:All the 7 cases showed severe constant concentric stenosis in the lower part of the esophagus. The “pendulum like”sign below the stenosis was seen in 5 cases. The intramural canaliculus sign of the stenotic region was seen in 2 cases.Conclusion: The radiologic manifestations of CTE are characteristic, and the correct diagnosis may be established preoperatively.
