摘　　要：目的:研究干燥综合征(SS)腮腺造影排空时间。方法:所有资料分成非口干正常组、口干正常组及SS组,分别对各组15分钟及60分钟的腮腺造影排空像进行分析,并随机对部分患者进行长时间的追踪观察。结果:非口干正常组60分钟排空像显示大部分排空(9/12侧)和完全排空(3/12侧);口干正常组60分钟排空像未见大部分排空征象;干燥综合征组60分钟排空像多数显示为无明显排空(44/58侧),无口干症状的病例排空情况较好;在1.5小时～6个月的长时间追踪观察中,SS组及正常组中只分别有2侧显示完全排空像。结论:60分钟排空像显示无明显排空视为异常;绝大多数SS病例60分钟内的排空像是无明显排空的;口干症状的有无与排空时间密切相关;腮腺造影排空像对于诊断干燥综合征有较高的敏感性,而特异性相对较差。Objective： To study emptying time of contrast medium during parotid sialography with Sjogren＇s syndrome（SS）. Methods： The patients were divided into normal group without symptom of oral cavity dryness, normal group with symptom of oral cavity dryness and SS group. The images of parotid sialography at 15min and 60min were analyzed, and some of the patients were randomly selected for long term follow up observation. Results： In the normal group without symptom of oral cavity dryness, most of the contrast medium was excreted（9/12 sides）, completely excreted（3/12 sides） at 60min images. In the normal group with symptom of oral cavity dryness, contrast medium was not excreted in most cases at 60min images. In the SS group most cases showed no obvious excretion（44/58 sides）. In cases with no oral cavity dryness the emptying of contrast medium was well. In the follow up observation from 1.5 hours to 6 months only 2 sides of SS patient showed bilateral complete excretion. Conclusion： When there is no obvious excretion of contrast medium on the 60min film it is considered to be abnormal as seen in most of the SS patients. Excretion time is correlated with the symptom of oral cavity dryness. The emptying of contrast medium on parotid sialography has high sensitivity in the diagnosis of SS, but its specificity is relatively poor.
