Swallowing function in the eldaly

我们对65岁及以上的吞咽困难或咽喉感觉异常的患者进行了修订后的测压法和修订后的咽食管x线图的研究，得到以下结果：我们将12例接受测压的患者分为两组；6例有神经肌肉疾病，6例无疾病。但两组在吞咽压力传导曲线的模式和吞咽压力传导速度上似乎没有差异。并将54例行咽-食管x线透视的患者分为3组；第1组有神经肌肉疾病患者18例，第2组无吞咽困难疾病患者20例，第3组有杂因吞咽困难患者16例。过早流进咽和喉部的透视阳性检出率分别为15例（81%）、8例（40%）和8例（50%）。2组20例无吞咽困难的患者，在一系列的透视检查中，我们未发现吞咽相关解剖部件的共同病理运动。本研究对上述几点进行了探讨，以阐明吞咽反射启动障碍被认为是老年人吞咽困难的主要原因。我们得到的事实是，吞咽反射延迟启动的发生率在老年人中上升，但未能得到这一现象的确切原因。

We have got the following results through the investigations of a revised manometry and a revised pharyngo-esophageal fluorography applied to the patients with dysphagia or abnormal sensations in the throat who are 65 years old or older. We divided the 12 patients who underwent the manometry into two groups ; 6 patients with neuromuscular disease and 6 without disease. But there seems no difference between two groups as to both the patterns of conduction curves of swallowing pressure and also the conduction velocity of the swallowing pressure. And we also divided the 54 patients who underwent the pharyngo-esophageal fluorograpgy into 3 groups ; group 1 of 18 patients with neuromuscular disease, group 2 of 20 patients without any dysphagic disease, and group 3 of 16 patients with dysphagia of miscellaneous causes. The percentages of positive fluoroscopic findings of premature flow into the pharynx and the larynx are 15 cases (81%), 8 cases (40%), and 8 cases (50%) respectively. We could not find any common pathological movements of anatomical components involved in swallowing in the series of fluoroscopic examination of group 2 of 20 patients without any dysphagic disease.In this study, several points mentioned above were investigated in order to clarify the disorder of swallowing reflex initiation which are thought to be the main cause of dysphagia in the elderly. We got the facts that the incidence of delayd swallowing reflex initiation goes up in elder generations but failed to get the precise cause of that phenomena.
