A total of 661 esophageal motility studies were performed in 568 patients over a five year period in a tertiary care hospital. Patients referred for investigation generally presented with one of three symptoms: dysphagia, reflux or chest pain. Dysphagia was more closely identified with organic esophageal dysfunction than other symptoms. Normal studies were recorded in 201 instances (30%). Studies demonstrating either a major or minor non-specific motor disorder were found in 380 cases (58%). Achalasia was found in 48 patients who underwent 65 procedures (10%). Scleroderma was diagnosed in 7 patients (1%). Elderly patients were not found to have diminished esophageal function when compared to a young group.
在一家三级护理医院的五年时间里，共对568名患者进行了661次食管动力研究。因调查而转诊的患者通常表现出三种症状之一：吞咽困难、反流或胸痛。与其他症状相比，吞咽困难与器质性食管功能障碍的关联更为密切。201例（30%）研究结果正常。380例（58%）研究显示存在主要或次要的非特异性运动障碍。48例患者（10%）接受了65次手术，被诊断为贲门失弛缓症。7例患者（1%）被诊断为硬皮病。与年轻组相比，未发现老年患者食管功能减退。
