The incidence of achalasia in the Nottingham area between 1966 and 1983 has been examined using hospital diagnostic indices supplemented by personal endoscopy files. All patients were traced and the date of death recorded where relevant. A total of 53 cases was confirmed and the incidence was 0.51 cases/10(5)/year and the prevalence on 31 December 1983, was 8/10(5). The age-specific incidence of the disease increased in older groups. The duration of dysphagia before diagnosis was no less with greater availability of manometry and endoscopy.
利用医院诊断指标并辅以个人内镜检查档案，对1966年至1983年诺丁汉地区贲门失弛缓症的发病率进行了调查。对所有患者进行了追踪，并在相关情况下记录了死亡日期。共确诊53例，发病率为0.51例/10⁵/年，1983年12月31日的患病率为8/10⁵。该病的年龄特异性发病率在老年组中有所增加。随着测压法和内镜检查的可及性提高，诊断前吞咽困难的持续时间并未缩短。
