对７０例下咽癌患者进行了钡透检查，结果阳性率为７８．６％，假阴性率为２１．４％。手术证实癌肿累及颈段食管者２６例，其食管钡透阳性率为６９．２％，假阴性率为３０．８％。结合手术所见，探讨了食管钡透在下咽癌诊断中的临床意义；认为其方法简单、易行，对累及颈段食管者有助于明确病变下限。
A total of 70 hypopharyngeal cancer patients underwent barium-based examination. The positive rate was 78.6% and the false-negative rate was 21.4%. Surgery confirmed 26 cases of cancer involving the cervical esophagus, the positive rate of esophageal barium penetration was 69.2%, false negative rate was 30.8%. Combined with the surgical findings, explore the clinical significance of esophageal barium in the diagnosis of hypopharyngeal carcinoma; that the method is simple and easy to carry out on the involvement of the cervical esophagus will help clear the lower limit of the lesion.
