Esophageal manometry is considered the gold standard in the diagnosis of esophageal motility disorders. Cine-esophagogram using barium is also a good investigation to screen patients for motor disorders of the esophagus. Comparison between these two investigations has not often been reported in patients with progressive systemic sclerosis (PSS).
To determine relative merits of cine-esophagogram and esophageal manometry in detecting esophageal motor dysfunction in PSS patients.
Thirty-five patients with PSS irrespective of esophageal symptoms underwent esophageal manometry and cine-esophagogram, results and their were compared.
Sensitivity and specificity of cine-esophagogram as compared to manometry were 96.1% (95% CI 88.7%-100%) and 55.5% (95% CI 23%-87.9%) respectively. Its positive predictive value was 86%.
While esophageal manometry can identify esophageal motor disorder in PSS, cine-esophagogram can be resorted to in doubtful situations, for confirmation of diagnosis.
食管测压被认为是诊断食管动力障碍的金标准。使用钡剂的食管动态造影也是筛查食管动力障碍患者的一项很好的检查。这两种检查方法在进行性系统性硬化症（PSS）患者中的比较报道并不常见。
确定食管动态造影和食管测压在检测PSS患者食管运动功能障碍方面的相对优点。
35例无论有无食管症状的PSS患者接受了食管测压和食管动态造影，并对结果进行了比较。
与测压相比，食管动态造影的敏感性和特异性分别为96.1%（95%可信区间88.7%-100%）和55.5%（95%可信区间23%-87.9%）。其阳性预测值为86%。
虽然食管测压可以识别PSS患者的食管动力障碍，但在诊断存疑的情况下，可以采用食管动态造影来确诊。
