Esophageal motility was studied in 21 patients with Sjögren's syndrome, and in 25 normal volunteers, in order to record the prevalence and type of esophageal motor abnormalities. Esophageal motor abnormalities were detected in seven of the 21 patients (33.3%). These esophageal abnormalities did not correlate with the presence of dysphagia, the extraglandular involvement, or the presence of autoantibodies.
对21例干燥综合征患者和25名正常志愿者进行了食管动力研究，以记录食管运动异常的发生率和类型。21例患者中有7例（33.3%）检测到食管运动异常。这些食管异常与吞咽困难的存在、腺外受累情况或自身抗体的存在均无相关性。
