Videofluoroscopic swallowing studies do not routinely obtain images of the esophagus. We incorporated a single esophageal screening swallow into our videofluoroscopic swallowing study protocol. The purpose of this study was to compare findings from "esophageal screening" with the results of full esophagram.
Patients undergoing videofluoroscopic swallowing studies with an esophageal screen followed by full esophagram between January 1, 2009, and October 1, 2009, were retrospectively reviewed. Comparison of esophageal screening and esophagram results were undertaken, with esophagram used as the gold standard.
Seventy-four patients underwent esophageal screening and esophagram. Sensitivity of esophageal screening is 63% (CI 50%-73%); specificity is 100% (CI 39%-100%). Positive and negative predictive values of esophageal screening were 100% and 13%, respectively.
Esophageal screening identified 44/70 (63%) patients with esophageal disease. Esophageal screening is a simple tool that may guide further esophageal investigation. The sensitivity of esophageal screening is limited (63%). If clinical suspicion is high, formal esophagram should be considered.
荧光透视吞咽研究通常不会对食管进行成像。我们在荧光透视吞咽研究方案中纳入了单次食管筛查吞咽。本研究的目的是比较“食管筛查”与全食管造影的结果。
回顾性分析 2009 年 1 月 1 日至 2009 年 10 月 1 日期间行荧光透视吞咽研究并进行食管筛查和全食管造影的患者。以食管造影为金标准，比较食管筛查和食管造影的结果。
74 例患者进行了食管筛查和食管造影。食管筛查的敏感性为 63%（置信区间 50%-73%）；特异性为 100%（置信区间 39%-100%）。食管筛查的阳性预测值和阴性预测值分别为 100%和 13%。
食管筛查发现 70 例食管疾病患者中的 44 例（63%）。食管筛查是一种简单的工具，可能有助于进一步进行食管检查。食管筛查的敏感性有限（63%）。如果临床怀疑很高，应考虑进行正式的食管造影。
