CT imaging in congenital esophageal atresia, tracheo-esophageal fistula (TEF ) comparing with surgical results

SUMMARY:

Purpose: To review some CT signs in congenital esophageal atresia, tracheo-esophageal fistula (TEF) and compare the CT findings with surgical results.

Materials and Methods: Images, CT diagnostic results were collected and compared with the surgical descriptions in 7 cases TEF from 12/2007-11/2010 at Binh Dinh hospital.

Results: Direct signs: atresis image of esophageal was visualized in 100% cases. The image of fistula between proximal esophagus-trachea: true positive is 2/3 cases, true negative is 3/4. The image of fistula distal esophagus-trachea: true positive is 3/6 cases, true negative are 1/1. Indirect signs: pneumonia and esophageal dilatation were visualized in 100% cases. Gaseous distention of the stomach and bowel was visualized in 3/4 cases which exist only lower fistula and 2/2 cases which exist both upper and lower fistula.

Conclusion: Between CT with surgery is concordantly in 5/7 cases, nonconcordantly in 2/7. Key words: esophageal atresia, tracheoesophageal fistula, congenital tracheoesophagus
