A retrospective study of 48 patients, living in the City of Cardiff, diagnosed as having achalasia between 1926 and 1977, was undertaken. The incidence of achalasia was 0.4/10(5)/year. One previous study in Rochester, Minn., of 11 patients had a comparable incidence of 0.6/10(5)/year. Our study failed to identify any aetiological factors.
对1926年至1977年间居住在加的夫市、被诊断患有贲门失弛缓症的48例患者进行了回顾性研究。贲门失弛缓症的发病率为0.4/10⁵/年。此前在明尼苏达州罗切斯特市对11例患者进行的一项研究，其发病率与之相当，为0.6/10⁵/年。我们的研究未能确定任何病因因素。
