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.
