Infantile hypertrophic pyloric stenosis: Long-term audit from a general surgical unit

This article describes a 22 year experience of a general surgical unit in the treatment of infantile hypertrophic pyloric stenosis (I HPS). The hospital course of 229 IHPS patients is reviewed. The male:female ratio was 3.6:1, median age 6 weeks (range 2-26 weeks) with a positive family history in 8.3%. The diagnosis of IHPS was established clinically by palpation of a “pyloric tumour” during a pre operative test meal/clinical examination in 92.6%; in the remainder, the diagnosis was made radiologically.
