原发性食管运动障碍是指食管本身或全身不存在会影响食管运动的器质性疾病时所出现的食管运动异常.现将文献上报道较多的几种分述于下.食管上端括约肌紊乱食管上端括约肌可能由食管上端的环形平滑肌参与构成,用测压方法测出的长度约为2～4cm,比环咽肌的解剖长度为长.食管上端的原发性运动障碍比较少见,主要表现为静息时张力异常和环咽肌的放松与开放异常.前者表现为咽部有被某种东西堵塞的感觉,其时括约肌静息压力可升 Esophageal motility disorder refers to the esophagus itself or the body does not exist or affect the esophageal organic diseases will occur when the esophageal motility abnormalities are now reported in the literature several more points in the next upper esophageal sphincter disorders Upper esophageal sphincter may be composed of the upper smooth muscle of the esophagus, measured by pressure measurement of the length of about 2 ~ 4cm, longer than the anatomical length of the cricopharyngeal muscle. The upper esophageal primary dyskinesia is rare, the main performance Resting tension and anomalies of the relaxation and opening of the anomalies of the cricopharyngeal pharynx, the former manifested as something blocked by the feeling of the throat, when the resting pressure of the sphincter can rise
