[X-ray VTR analysis of esophagocardiac motion in cases of cervical dysphagia].

Using X-ray VTR motion analysis to diagnose a total of 103 cervical dysphagial cases, we obtained the following conclusions. Among these dysphagial cases, there were only 32 cases (31%) of clear organic or functional disease which we commonly considered to be the cause of dysphagia, and there were no less than 71 cases (69%) in which we could not identify the cause of the dysphagia. In 29 of these 71 cases, recording conditions of whole esophageal systole and diastole through the passage of contrast medium (Barium) were insufficient. We compared the remaining 42 cases with 42 normal cases, focussing on the lower esophagocardiac movement. In these dysphagial cases, angle of barium inflow tended to steepen statistically, and Barium discharge of the ampulla was tended towards incomplete discharge. In conclusion, this method is thought to contribute to the diagnosis of dysphagial cases except clear organic or functional diseases which we commonly consider to be the cause of the dysphagia.
