在食管无器质性病变的患者,吞咽困难常被认为系食管运动功能紊乱所致。但当吞钡检查正常,食管测压正常,反流诊断试验阴性时,便难以确诊。由于吞咽困难常于进食固体食物时出现,因此作者用闪烁造影术观察固体食团通过食管的情况。对象及方法:共16例,吞咽困难平均病程4年(范围0.5～11年),均属间或发生。除2例外,14例吞钡透视至少4次,均正常。所有患者均作食管测压、pH反流试验、酸灌注试验及酸清除试验,未发现异常。闪烁摄影方法:患者仰卧于连有电脑的γ照相机下,给予含有过~(99m)锝酸盐75MBq的固态胶块4 ml。喝一口水后,将此胶块和水15ml同时一次咽下。咽下前不准咀嚼,每次试验前30秒禁止自发性吞咽。用一连接电脑的标绘仪记录食团从环状软骨水平至胃的传输图像,据
In patients with esophageal non-organic disease, dysphagia is often considered as a result of dysfunction of esophageal motility. However, when barium swallowed normal, normal esophageal manometry, reflux diagnostic test negative, it is difficult to diagnose. Because dysphagia often occurs when eating solid foods, the authors used scintigraphy to observe the passage of solid boluses through the esophagus. Subjects and Methods: A total of 16 cases, the average duration of dysphagia for 4 years (range 0.5 to 11 years), are between or occur. In addition to 2 cases, 14 cases of barium swallow at least 4 times, were normal. All patients were esophageal manometry, pH reflux test, acid perfusion test and acid removal test, found no abnormalities. Blinking Photographs: The patient was supine on a computer-mounted gamma camera and given 4 ml of a solid gel patch containing 75 MBq of ~ (99m) pertechnetate. Drink a saliva, this gel and water 15ml at the same time swallowed. Do not chew before swallowing. Do not swallow spontaneously 30 seconds before each test. With a computer connected to the plotter records the mass from the annular cartilage to the stomach transmission image, according to
