Motility disorders of the esophagus can cause a variety of esophageal complaints. Radiographic evaluation of the esophagus using multiple single swallows of barium provides an accurate assessment of esophageal function. Primary esophageal motility disorders that can be diagnosed include achalasia, diffuse esophageal spasm, and nonspecific esophageal motility disorder. Secondary esophageal motility disorders, especially those related to collagen disease, are also well detected. Manometric and clinical correlations in recent years have clarified the role of radiology in evaluating normal and abnormal esophageal function.
食管动力障碍可引发多种食管相关症状。通过多次吞咽少量钡剂对食管进行放射学评估，能够准确地评估食管功能。可诊断出的原发性食管动力障碍包括贲门失弛缓症、弥漫性食管痉挛和非特异性食管动力障碍。继发性食管动力障碍，尤其是与胶原病相关的，也能被很好地检测出来。近年来的测压与临床相关性研究明确了放射学在评估正常和异常食管功能中的作用。
