We reviewed the incidence rates of infantile hypertrophic pyloric stenosis (IHPS) and pylorospasm in Saskatchewan from 1970 to 1985 and found a marked decrease in the rates after 1976. As expected, there was a preponderance of males among those with IHPS and among those with pylorospasm discharged from hospital between 1 and 3 months of age. No seasonal pattern was observed. We believe that the decrease in incidence rates was related to environmental influences, such as changes in the methods of feeding observed since 1977.
我们回顾了1970年至1985年萨斯喀彻温省婴儿肥厚性幽门狭窄(IHPS)和幽门痉挛的发病率,发现1976年后发病率显著下降。正如预期的那样,1至3个月大出院的患有IHPS和幽门痉挛的婴儿中男性占多数。未观察到季节性模式。我们认为发病率的下降与环境影响有关,比如自1977年以来观察到的喂养方式的变化。
