食管穿孔是消化道严重而致命的损伤,一般食管穿孔的造影检查都把水溶性碘制剂作为首选的对比剂。但当检查结果为阴性时,是否需用钡剂进一步检查?为明确此问题,研究了67例怀疑食管穿孔的患者,先用水溶性碘剂作食管检查,49例为阳性。18例阴性者,进一步以钡剂(100％wt/vol)作食管检查。结果,其中4例可见钡剂外漏,检查后进行患者随访未见并发症发生。该组资料显示食管穿孔水溶性碘剂造影的漏诊率为22％。
Esophageal perforation is a serious and fatal gastrointestinal injury, the general esophageal perforation of the contrast examination of water-soluble iodine preparations as the preferred contrast agent. However, when the test result is negative, is it necessary to use barium for further examination? To clarify this problem, the study of 67 patients suspected esophageal perforation, first with water-soluble iodine for esophageal examination, 49 cases were positive. 18 patients were negative, further barium (100% wt / vol) for esophageal examination. Results, of which 4 cases of barium leakage can be seen, after the follow-up examination no complications occurred. The data show that the rate of missed diagnosis of esophageal perforation of water-soluble iodine contrast agent was 22%.
